Autoresuscitation'' (AR) is the spontaneous recovery from hypoxic apnea by gasping. We examined aspects of heart function in two situations: 1) the maturationally acquired failure of AR that is characteristic of SWR, but not BALB/c, weanling mice and 2) AR failure in BALB/c mice induced by repeated exposures to anoxia. We determined maturational changes in heart and liver glycogen. Unlike liver glycogen levels, heart glycogen levels in SWR mice differed from those in BALB/c mice. They were consistently much lower throughout maturation and reached a nadir during the brief period when SWR weanling mice are vulnerable to AR failure. Also, rate of cardiac glycogen utilization in vulnerable SWR mice was lower than that of same-aged BALB/c mice and was nil during the latter one-half of the gasping stage when heart function is critical for AR success. Therefore, because glycogen utilization reflects cardiac work, heart failure could explain AR failure in SWR weanlings. Additionally, the increase in hypoxic heart rate that occurs with maturation is developmentally delayed in SWR mice, and this may contribute to their AR failure. Cardiac glycogen was not fully depleted in BALB/c mice during repeated anoxic exposures, indicating other reasons for AR failure. We view these findings as a potential model for the age-related peak inincidence of sudden infant death syndrome.

However, there is little information on how the interaction between zooplankton grazers and their phytoplankton food changes along an environmental gradient of lake depth. We contrasted resource availability for daphniid zooplankton populations living in two shallow, unstratified lakes and in two deep, stratified lakes using a novel growth bioassay. Stratified lakes had consistently lower resource richness than shallow unstratified lakes. To test whether resources were important in explaining differences in daphniid composition of shallow and deep lakes, we performed reciprocal transplant experiments. We raised daphniids typical of shallow (Ceriodaphnia reticulata) and deep (Daphnia dentifera) lakes in the resources from replicate shallow and deep lakes and monitored survival and reproduction. The two species exhibited a performance trade-off, measured by life table r and R-0, across a gradient in natural resource richness. D. dentifera had higher relative fitness than C. reticulata when raised in the poorest resource environment from a deep lake. However, under richer resource conditions typical of shallow lakes, C. reticulata outperformed D, dentifera. We further created a gradient in natural resource quantity (by dilution) to test whether this trade-off in species relative fitness involved aspects of resource quality. No trade-off in species performance was evident across the dilution gradient, indicating that resource quality was important to the trade-off. We conclude that shifts in daphniid species composition along a gradient of lake depth involve an adaptive tradeoff in ability to exploit rich versus poor resource quality.

However, the importance, origin, and significance of the mesenteric fat hypertrophy in this chronic inflammatory disease am unknown. Peroxisome proliferator-activated receptor gamma (PPAR gamma) is a crucial factor involved in the homeostasis of adipose tissue, a major source of biologically active mediators. Methods: Intraabdominal fat accumulation was quantified using a magnetic resonance imaging method in patients with Crohn's disease and controls. PPAR gamma and inflammatory cytokines synthesized by mesenteric adipose tissues were assessed by quantitative polymerase chain reaction, in situ hybridization, and immunohistochemistry. Results: In vivo, patients with Crohn's disease have an important accumulation of intra-abdominal fat. This mesenteric obesity, present from the onset of the disease, is associated with overexpression of PPAR gamma and tumor necrosis factor (TNF)-alpha, synthesized, at least in part, by adipocytes. Conclusions: These results suggest that confined increased PPAR gamma mesenteric concentrations could lead to the mesenteric fat hypertrophy, which could actively participate through the synthesis of TNF-alpha in the inflammatory response.

J Devincre, B; Veyssière, P; Saada, G Devincre, B; Veyssière, P; Saada, G Simulation of the plastic flow in Ni3Al:: work hardening and strain-rate sensitivity PHILOSOPHICAL MAGAZINE A-PHYSICS OF CONDENSED MATTER STRUCTURE DEFECTS AND MECHANICAL PROPERTIES English Article ORDERED ALLOYS; L1(2) ALLOYS; STRESS; DISLOCATIONS; TEMPERATURE; DYNAMICS; MOTION; MODEL The origin of the anomalous temperature dependence of the giant work-hardening rate and of the modest strain-rate sensitivity observed in many L1(2) alloys is investigated by means of an 'end-on' simulation of dislocation dynamics in Ni3Al. The present model reproduces most of the atypical mechanical properties observed experimentally. The study of the evolution of the distribution of the Kear-Wilsdorf locks during plastic deformation indicates that the order of magnitude of the work-hardening rate stems from a preferred exhaustion of the weakest locks. In addition, the low strain-rate sensitivity measured is found to rely on the absence of a correlation between the dislocation properties which provide the plastic strain and those which determine the flow stress level.

Design:Prospective, psychometric evaluation. Setting: Sixteen-bed surgical intensive care unit (SICU) of a 937-bed tertiary care, university-affiliated teaching hospital. Patients: Twenty-five randomly selected, adult, mechanically ventilated, nonneurosurgical patients who were admitted to the SICU greater than or equal to 12 hrs after surgery and were not receiving neuromuscular blockers. Intervention: Four hundred assessments (eight per patient) were completed consecutively but independently, in pairs, at standardized times (both day and night) by two nurses who were preselected for each assessment from a pool of 32 pretrained SICU nurses. Measurements and Main Results:To estimate validity, paired assessments (four/patient) compared the MAAS result with the subjective assessment using a 10-cm visual analog sedation scale, the percent change in blood pressure and heart rate from the previous 4-hr baselines, and the number of recent agitation-related sequelae. To estimate reliability, paired assessments (four/patient) measured correlation between assessments of the same type (e.g., MAAS-MAAS). Generalized estimating equations, which accounted for the four repeated measures in each patient, supported MAAS validity by finding a linear trend between MAAS and the visual analog scale (p < .001), blood pressure (p < .001), heart rate (p < .001), and agitation-related sequelae (p < .001) end points. The MAAS (kappa = 0.83 [95% confidence interval, 0.72 to 0.94]) was found to be more reliable than subjective assessment using the visual analog scale (intraclass correlation coefficient = 0.32 [95% confidence interval, 0.05 to 0.55]). Conclusions: The MAAS is a valid and reliable sedation scale for use with mechanically ventilated patients in the SICU.

J DeWoody, KL DeWoody, KL Use of matrix designs in stability studies: A simulation study DRUG INFORMATION JOURNAL English Article drug stability study; matrix designs; uniform matrix designs; expiration dating period A stability study is designed to study the degradation profile of a drug product over time. It is required that at least three batches of the drug product in its finished form be studied over time. Often it is desired to manufacture the product in various forms, using a variety of packaging options. If three batches of product are studied for each combination of these experimental conditions at each of the recommended sampling times, the cost of the study can be substantial. Simulation studies are used to examine the effect of matrix designs; it is shown that the performance of these reduced testing plans is similar to the full sampling plan in terms of power to detect slope differences and estimation. of the expiration dating period.

INTERNATIONAL JOURNAL OF FERTILITY AND WOMENS MEDICINE English Article fertility outcome; hysterosalpingography; fallopian tube disease; laparoscopy; prognostic significance TUBAL PATHOLOGY; INFERTILITY; LAPAROSCOPY; DIAGNOSIS; ACCURACY Objective-To assess the value of hysterosalpingography (HSG) in diagnosing tubal patency and peritubal adhesions. Patients and Methods-HSG was followed whenever possible by diagnostic laparoscopy with chromopertubation to give the final prognosis in cases of infertility. Results-Normal HSG findings were obtained in 669 women, and abnormal ones in 306. No significant correlation was found between age of patient, duration, type of infertility, and HSG findings. Tubal blockage was seen in 89.2% and uterine factor in 9.4% of cases. Peritubal adhesions were suggestive in 12.75% of cases. On laparoscopy, done in about half of these women, findings were in agreement with HSG in 59.87% of cases. Follow-up was carried out whether the woman conceived, had a laparotomy, or required further investigations. Conclusion-Although somewhat insensitive, the high specificity of hysterosalpingography makes it very helpful for ruling out tubal disease, even where endoscopic evaluation is available.

To perform stable transfections of human chondrocytes under conditions that allow the maintenance of the chondrocyte-specific phenotype, and to examine the effects of the stable transfection of a mutated type II procollagen gene (COL2A1) on the structure of the cartilaginous extracellular matrix produced in vitro. Methods. A type II procollagen minigene that lacks exons 16-27 was stably transfected into human fetal epiphyseal chondrocytes in vitro, Expression of the minigene was detected by reverse transcriptase polymerase chain reaction, and the encoded protein was identified by Western blot with a human type II collagen-specific antibody. The cartilaginous extracellular matrix produced by the cultured transfected chondrocytes was characterized using histochemical staining, polarized light microscopy analysis, and transmission electron microscopy, Results. A shortened type II collagen encoded by the transfected minigene was biosynthesized and produced in the cultures of transfected cells, Histologic analyses demonstrated a more dense, negatively charged cartilaginous matrix in control cultures. In contrast, COL2A1 minigene-transfected cultures were more cellular, were populated with cells of irregular shape and less-chondrocytic appearance, contained abundant intracellular dense granules, and were sur rounded by a less-dense matrix. Polarized light microscopy and transmission electron microscopy revealed a well-organized collagen fibrillar matrix in untransfected, control chondrocyte cultures, while the matrix in the transfected cultures was less birefringent and contained numerous truncated collagen fibrils, Conclusion. The findings illustrate the feasibility of gene transfer into human fetal chondrocytes under conditions that allow the preservation of their specific phenotype, and also shed light on the function of type II collagen in the maintenance of the structural integrity of articular cartilage matrix.

J Di Blasi, C; Signorelli, G; Portoricco, G Di Blasi, C; Signorelli, G; Portoricco, G Countercurrent fixed-bed gasification of biomass at laboratory scale INDUSTRIAL & ENGINEERING CHEMISTRY RESEARCH English Article FLUIDIZED-BED; FLASH PYROLYSIS; RAW GAS; STEAM A laboratory-scale countercurrent fixed-bed gasification plant has been designed and constructed to produce data for process modeling and to compare the gasification characteristics of several biomasses (beechwood, nutshells, olive husks, and grape residues). The composition of producer gas and spatial temperature profiles have been measured for biomass gasification at different air flow rates. The gas-heating value always attains a maximum as a function of this operating variable, associated with a decrease of the air-to-fuel ratio. Optimal gasification conditions of wood and agricultural residues give rise to comparable gas-heating values, comprised in the range 5-5.5 MJ/Nm(3) with 28-30% CO, 5-7% CO2, 6-8% Hz, 1-2% CH4, and small amounts of C-2- hydrocarbons (apart from nitrogen). However, gasification of agricultural residues is more difficult because of bed transport, partial ash sintering, nonuniform flow distribution, and the presence of a muddy phase in the effluents, so that proper pretreatments are needed for large-scale applications.

Prevalence estimates and costs of the definition procedure may vary depending on different screening strategies, We evaluated the impact of these different strategies on the overall diagnostic procedure and on stroke prevalence estimates in the Italian Longitudinal Study on Aging. A population sample of 5,632 individuals aged 65-84 years was screened for stroke by a simple question on previous stroke diagnosis, questions on possible stroke symptoms and a simple neurological examination. Those screened positive by any of these procedures were fully examined by a neurologist for conclusive diagnosis, We determined the positive predictive value of each procedure on the final stroke diagnosis and calculated prevalence as if each procedure had been used separately, Using the three procedures combined, the prevalence rate was 6.0% (95% confidence interval, 5.4-6.7%), If each procedure had been used as the unique screening tool, the rates would have been 5.1% (4.5-5.7%), 4.1% (3.6-4.7%) and 2.3% (1.9-2.7%), a nd positive predictive values 66.4, 55.2 and 45.1%, respectively, Different screening procedures can affect stroke prevalence estimates. Compared to more complex screening strategies, the use of a simple question about previous diagnosis as the unique screening tool leads to only a slight underestimation of stroke prevalence and avoids a 66% increase in the number of subjects to be examined in a second-level specialist evaluation, potentially reducing the costs of the overall diagnostic procedure.

Spectra obtained by analysing the plasma optical emission at various distances from the ablated graphite surface show how the composition and temperature vary within the plasma plume. The collected data allow the identification of various emitting species at different regions of the expanding plasma and estimation of their velocities. The further ahead in the plume, the more the ablated material is ionised. Temperatures are determined from the continuous broad background, while the plasma cools as it expands. The influence of substrate temperature on the resulting film structure is also studied through Raman scattering measurements. Optical microscope pictures are taken to evaluate surface quality. Plasma ionisation degree and kinetic energies are enough to grow diamond-like films, but high substrate temperatures favour graphitic order. (C) 1999 Elsevier Science S.A. All rights reserved.

Part of an unmodified 40 km(2) catchment within the South-west New Zealand World Heritage Area, the Hapuka Estuary, formed behind a 5-km long barrier beach, provides considerable ecological value as well as baseline, conservation advocacy and educative potentials both in a national and international context. Seventy-four quadrats were sampled randomly along five transects at right angles to the main Hapuka River. Eight plant communities comprising 141 native and thirteen exotic vascular species, were differentiated using multivariate analyses, from bare mud (mean elevation 1.23 +/- 0.24 m above Mean Low Water Spring (MLWS)), saltmarsh and shrubland associations through to the adjacent podocarp-broadleaved rain forest (4.53 +/- 0.74 m above MLWS). Bulk density of the upper 10 cm of substrate varied from a maximum of 1.15 g cm(-3) in the lowest elevation association to a minimum of 0.15 g cm(-3) in the rain forest. pH showed a similar trend with values of 6.97 and 4.31, respectively. The reverse pattern was evident with organic matter, with the highest content (53% ODWt) in the rain forest substrate. The water which irrigates the saltmarsh at high tide reaches 15-19 parts per thousand salinity on calm days but may be much less saline when moderate to strong southerly winds counter the tidal influence. Northerly winds, or a southern outlet through the barrier beach, intermittently evident in the past, are likely to enhance salinity of the tidal waters across the saltmarsh. Ordination of the vegetation samples indicated a very strong gradient associated with Axis 1 (eigenvalue=0.872) and Axis 2 (eigenvalue=0.461). Vector fitting of nine measured environmental factors indicated a strong positive correlation with Axis 1 of the ordination, of soil pH, sodium and conductivity, and negative correlations with elevation, soil water, organic matter and potassium contents.

A procedure is developed for extracting the chemical diffusion and surface exchange coefficients for oxygen by use of the asymptotic equations derived for the current response to a potential step at short and long times. It is shown that, while the formation of interfacial phases by reaction between the sample and the electrolyte may affect the surface exchange coefficient, the chemical diffusion coefficient data determined by the present approach are independent of such interfacial phenomena. The consistency of data obtained from several specimens with varying thickness and manner of interfacing with the electrolyte validates the diffusion model and the method used for data analysis. An oxygen permeation cell is also developed in this work as a modification of the diffusion cell. The new cell allows monitoring of the permeation rate by electrochemical means. The steady-state permeation data obtained by the permeation cell are consistent with the chemical-diffusion and surface-exchange coefficients measured by the blocked diffusion cell as long as the assumptions of the related theoretical models are satisfied. This is a further validation of the diffusion model and the related methodology developed here for obtaining the necessary data for characterizing oxygen exchange and transport in such materials.

J Diether, S; Schaeffel, F Diether, S; Schaeffel, F Long-term changes in retinal contrast sensitivity in chicks from frosted occluders and drugs: relations to myopia? VISION RESEARCH English Article contrast adaptation; myopia; chick; retina FORM-DEPRIVATION MYOPIA; EYE GROWTH; PATTERN ELECTRORETINOGRAM; CHROMATIC ABERRATION; 6-HYDROXY DOPAMINE; VISUAL EXPERIENCE; REFRACTIVE ERRORS; SPECTACLE LENSES; NERVE-SECTION; ACCOMMODATION Experiments in animal models have shown that the retina analyzes the image to identify the position of the plane of focus and fine-tunes the growth of the underlying sclera. It is fundamental to the understanding of the development of refractive errors to know which image features are processed. Since the position of the image plane fluctuates continuously with accommodative status and viewing distance, a meaningful control of refractive development can only occur by an averaging procedure with a long time constant. As a candidate for a retinal signal for enhanced eye growth and myopia we propose the level of contrast adaptation which varies with the average amount of defocus. Using a behavioural paradigm, we have found in chickens (1) that contrast adaptation (CA, here referred to as an increase in contrast sensitivity) occurs at low spatial frequencies (0.2 cyc/deg) already after 1.5 h of wearing frosted goggles which cause deprivation myopia, (2) that CA also occurs with negative lenses (- 7.4D) and positive lenses (+ 6.9D) after 1.5 h, at least if accommodation is paralyzed and, (3) that CA occurs at a retinal level or has, at least, a retinal component. Furthermore, we have studied the effects of atropine and reserpine, which both suppress myopia development, on CA. Quisqualate, which causes retinal degeneration but leaves emmetropization functional, was also tested. We found that both atropine and reserpine increase contrast sensitivity to a level where no further CA could be induced by frosted goggles. Quisqualate increased only the variability of refractive development and of contrast sensitivity. Taken together, CA occurring during extended periods of defocus is a possible candidate for a retinal error signal for myopia development. However, the situation is complicated by the fact that there must be a second image processing mode generating a powerful inhibitory growth signal if the image is in front of the retina, even with poor images (Diether, S., & Schaeffel, F.

Several alterations in growth hormone (GH) secretion have been reported in patients with chronic renal insufficiency. However, cholinergic modulation of somatotopic cell function has not been fully clarified in uraemic patients. To gain further insight into the disrupted mechanism of GH regulation in chronic renal failure, we investigated whether the blockade of cholinergic muscarinic receptor with pirenzepine could modify the response of GH to its physiological releasing hormone. Methods. Eight uraemic male patients on peritoneal dialysis and six normal controls were studied. All subjects underwent two endocrine tests in random order. In one of them placebo was administered 60 min before the injection of GH-releasing hormone (GHRH, 100 mu g, i.v. in bolus at 0 min). In another the muscarinic blocking agent pirenzepine, 100 mg p.o., was administered at that time. Blood samples for GH were collected at -60, 0, 15, 30, 45, 60 and 90 min. Results. Baseline plasma GH concentrations were similar in patients and controls. GH responses to GHRH were characterized by great interindividual variability in uraemic patients with regard to the amount and the time to maximal peak. In the placebo plus GHRH test, the maximum GH concentrations in patients (14.0+/-3.2 mu g/l) were similar to those reached by controls (18.0+/-3.1 mu g/l), although GH secretion was more sustained in patients. The area under the secretory curve (AUC) of GH secretion in patients was also similar to that found in controls (14.4+/-2.9 vs 15.4+/-3.3 mu g/h/l). When subjects were given pirenzepine before GHRH injection an abolishment of GHRH-induced GH release was observed in all controls and in all but one of the uraemic patients. The AUC of GH secretion was, therefore, significantly reduced both in uraemic patients (4.1+/-2.0 mu g/h/l, P<0.05) and in control subjects (2.0+/-0.3 mu g/h/l, P<0.05). Conclusion. These results suggest that GH secretion in uraemic patients is modulated, at least in part, by a cholinergic mechanism. The muscarinic blockade, possibly acting via an increase in somatosatin release, is able to inhibit GH release in response to direct pituitary stimulation with GHRH.

We examined radial growth trends in canopy and subcanopy sugar maple (Acer saccharum Marsh.) trees growing in gaps and non-gap areas in three second-growth, Allegheny northern hardwood forest stands in central New York. Our objective was to determine if a recent diffuse disturbance of the canopy caused by beech bark disease stimulated growth of sugar maple trees in gaps and throughout the forest. Annual radial growth (mm/yr) of canopy gap-edge trees and subcanopy trees in gaps was significantly greater than that of canopy trees and subcanopy trees in non-gap areas. During the period of beech bark disease-induced canopy decline, non-gap subcanopy trees exhibited an annual radial growth 30% higher and a radial growth rate (mm/yr/yr) four times greater than during the years prior to the disturbance. In contrast, canopy trees not adjacent to gaps showed no change in radial growth coincident with the disturbance. These results suggest that in forests with significant canopy deterioration, differences in tree growth between gap and nongap environments can be expected; however, positive growth responses among sub-canopy trees may not be limited to the area directly in gaps and instead may occur throughout the forest.

Their spectroscopic characteristics resemble that of the high-density quartz glass. In the meantime, the IR spectra of SiO2 glasses show that a small amount of water exists in SiO2 glasses in the form of OH-. It may be due simply to the small amount of water that contributes significantly to the amorphism of SiO2. The determination of refraction indices of SiO2 glasses shows that the refraction indices of SiO2 glasses and the high-density quartz glass are in good logarithmic relation with synthetic pressures.

J Ding, H; Lamb, RJ Ding, H; Lamb, RJ Oviposition and larval establishment of Sitodiplosis mosellana (Diptera: Cecidomyiidae) on wheat (Gramineae) at different growth stages CANADIAN ENTOMOLOGIST English Article GEHIN DIPTERA; SPRING WHEAT; MIDGE; SASKATCHEWAN; INFESTATION; CEREALS The wheat midge, Sitodiplosis mosellana (Gehin), infests wheat, Triticum aestivum L., heads only up to anthesis when pollination occurs. The termination of infestation might be due to a deterrence of oviposition or to a suppression of larval growth on developing seeds. These hypotheses were tested in the laboratory by measuring oviposition preference, larval development, and larval preference for plants at different growth stages. Females showed no preference for ovipositing on heads at any stage from the onset of heading up to and including anthesis, and continued to lay eggs at a reduced rate 10 days after anthesis. Survival of newly hatched larvae was reduced on seeds 3-4 days after anthesis and survival and development was greatly reduced on seeds 5 or 6 days after anthesis. Larvae moved away from older seeds and fed on younger seeds in a choice test. Given a hatching time of 5-6 days, a failure to infest wheat after anthesis is not due to oviposition deterrence at anthesis, but to suppression of larval growth and development which begins soon after anthesis.

The aim of this work was to study the effect of the timing of first cleavage on the cryosurvival of the resulting blastocysts, Following standard IVM and IVF, zygotes were cultured in modified synthetic oviduct fluid (SOF), with 10% fetal calf serum (FCS) added 48 hr post insemination, in a humidified atmosphere of 5% CO2, 5% O-2 and 90% N-2, Embryos which cleaved by 24, 27 30, 33, or 36 hr after insemination (IVF) were harvested and further cultured to the blastocyst stage (day 7 or day 8 post IVF), All developing blastocysts on days 7 and 8 were classified into three groups and were cryopreserved by vitrification. Group A consisted of blastocysts (<150 mu m, small blastocysts); group B consisted of expanded or hatching blastocysts (>150 mu m, large blastocysts); and group C consisted of morphologically poor quality blastocysts. The vitrification solution consisted of 6.5 M glycerol and 6% bovine serum albumin in PBS (VS3a). Thawed embryos were cultured further and survival was defined as the re-expansion and maintenance of the blastocoel over 24, 48, and 72 hr, respectively. Overall survival and hatching at 72 hr post-thawing was higher in blastocysts formed by day 7 than those formed by day 8 (60% vs, 40% survival; 63% vs. 45% hatching). Large blastocysts from day-7 and day-8 groups survived significantly better than small or poor quality blastocysts (76% vs. 63% and 31%; 72% vs. 30% and 26%, respectively; P < 0.05). Day-7 blastocysts from the 27- and 30-hr cleavage groups survived significantly better than those from the 36-hr group (63% and 66% vs. 25%, P < 0.05). Day-8 blastocysts from later cleaved (30 hr) zygotes had a higher survival than the 27-hr cleavage groups (52% vs. 26%, P < 0.05). These results indicate that the day of blastocyst appearance, developmental stage, and timing of the first cleavage post-insemination can influence the cryosurvival of bovine blastocysts following vitrification.

J Dirik, K; Göncüoglu, MC; Kozlu, H Dirik, K; Göncüoglu, MC; Kozlu, H Stratigraphy and pre-Miocene tectonic evolution of the southwestern part of the Sivas Basin, Central Anatolia, Turkey GEOLOGICAL JOURNAL English Article Sivas Basin; intracontinental basin; within-continental-plate eruptive setting; transpression; transtension BLOCK In central Anatolia there are several important basins developed mainly after closure of the northern branch of Neotethys. These are the Haymana, Tuzgolu, Ulukisla, Kizihrmak, Cankiri-Corum and Sivas basins. The Sivas Basin is located in the eastern part of central Anatolia between the Central Anatolian Crystalline Complex (CACC) in the north and Taurides in the south. The basement to the southeastern part of the basin consists of recrystallized limestone and clastics of the Permian-Lower Cretaceous Bunyan Metamorphics. These units are overlain by an Upper Cretaceous ophiolitic olistostrome that is overthrust by ophiolites and high pressure-low temperature metamorphic rocks. Lower Palaeocene cover units unconformably overlie this sequence. The basement to the northwestern part is constituted by CACC that includes a high temperature-low pressure polymetamorphic succession of Palaeozoic-Mesozoic age, overthrust by ophiolites and intruded by Upper Cretaceous post-collisional granitoids and syenitoids. The uppermost Maastrichtian-Palaeocene continental to shallow marine (lagoonal) unit unconformably overlies this unit. Upper Cretaceous-Palaeocene siltstone, shale, pelagic limestone, volcaniclastic rocks and basic volcanic rock intercalations of a within-continental-plate eruptive setting have also been developed on the basement unit. These sequences represent the products of an extensional episode during Late. Cretaceous-Palaeocene times in the region between the Taurides and CACC. The Middle Eocene is represented by a regional transgression which was followed by a compressional episode evidenced by thrust faults at the margins and continued regression in the central part of the basin. This compressional period continued up to the end of the Early Miocene. Units formed during this episode are overlain by Upper Miocene-Quaternary continental units intercalated with volcanic rocks formed in fault-controlled extensional basins. It is suggested that the palaeotectonic events were the result of terminal closure of the northern branch of Neotethys. However, the neotectonic events are the result of the collision of the Arabian Plate and Anatolides which causes a westward escape of the Anatolian Plate. Copyright (C) 1999 John Wiley & Sons, Ltd.

Because DC are efficient at Ag processing and could potentially present self Ags, we investigated the role of DC in the presentation of an encephalitogenic peptide from myelin basic protein (Ac1-11) in the induction of experimental autoimmune encephalomyelitis (EAE), To determine if DC could prime for EAE, we transferred DC pulsed with Ac1-11 or with medium alone into irradiated mice in combination with CD4(+) T cells isolated from a mouse transgenic for a TCR specific for Ac1-11 + I-A(u). Mice transferred with Ac1-11-pulsed DC developed EAE 7-10 days later, whereas mice receiving medium-pulsed DC did not. By day 15, all mice given peptide-loaded DC had signs of tail and hind limb paralysis, and by day 20 infiltration of Ac1-11-specific CD4(+) T cells was detected in the brain parenchyma, We also demonstrated interactions between Ac1-11-pulsed DC and Ac1-11-specific T cells in the lymph nodes 24 h following adoptive transfer of both cell populations.

In the years following the fall of the Berlin wall, 22 adults with uncorrected tetralogy presented to our center, mostly from former Eastern Block countries. Hypothesis: Our aim was to examine whether adults with tetralogy of Fallot benefit from late surgical repair. Nineteen patients underwent corrective surgery; hospital mortality was 16%. Follow-up examination 3.5 (0.3-9.7) years postoperatively consisted of chart review and a written questionnaire. Incidence of ventricular arrhythmias was 32% before surgery and increased to 50% 3.5 years after surgery. Clinical status and New York Heart Association classification were clearly improved. This was not reflected in an improvement of the patients' socioeconomic status, as none of the 9 patients in our group of 19, who were jobless before the surgery, experienced a change in employment status. Marital status did not change in any patient and, in particular, the number of single male patients remains high. Except for one nearly asymptomatic younger woman who had delivered four children, only one of the seven married women had delivered a child before and one of the younger women after cardiac repair, which we consider to be a positive effect of this surgery. Surgical correction of adult patients with tetralogy of Fallot carries a higher risk compared with correction in childhood. It improves quality of Life but does not change socioeconomic habits.

J Dixon, AFG; Kindlmann, P Dixon, AFG; Kindlmann, P Cost of flight apparatus and optimum body size of aphid migrants ECOLOGY English Article aphids; cost of flight apparatus; insects; migration; optimum body size WING-DIMORPHIC CRICKET; AFRICAN ARMYWORM MOTH; SPODOPTERA-EXEMPTA; REPRODUCTIVE INVESTMENT; ONCOPELTUS-FASCIATUS; MEGOURA-VICIAE; VETCH APHID; TRADE-OFF; MIGRATION; ALLOCATION The incorporation of aerodynamic considerations into an optimal energy partitioning model developed for aphids results in the prediction that migrants should be smaller and take longer to develop than nonmigrants. If individuals are structurally similar (i.e., the relative sizes of body parts and flight apparatus are similar), then both within and between species, aerodynamic considerations predict that biomass of wing muscles should scale relative to body mass with an exponent between 1 and 7/6, and wing beat frequency directly proportional to wing length for maximum power output to 1/2 power of wing length, when cruising. The empirical results for aphids indicate that within species, individuals of different sizes may not be structurally identical: large individuals appear to have proportionally smaller wings, and as theory predicts, appear to compensate for this by having proportionally larger wing muscles than small individuals. Interspecifically, aphids appear to be structurally identical both in terms of wing area, wing beat frequency, and in the relative size of the thorax. As predicted both intra- and interspecifically, large migrants, although having larger gonads, nevertheless have proportionally smaller gonads than small migrants. Empirical results also conform to the prediction that migrants should be smaller than nonmigrants, particularly so in large species. The prediction that the developmental time for migrants should be longer than for nonmigrants is supported by published data for aphids. The significance of these Endings is discussed in the context of Roff's hypothesis that insect migrants should be larger and develop faster than nonmigrants.

Sand samples collected from the reef flat were maintained over 7 d in triplicate cultures with N-enriched (100 mu M NO3), P-enriched (10 mu M PO4), and ambient seawater. A fourth experiment used a treatment of combined N and P enrichment. The sediment samples were assessed for chlorophyll a (Chl a) content and photosynthesis-irradiance (P-I) responses. P-I curves, constructed from area- and Chi a-specific metabolic rates, showed consistently higher maximal rates in the nutrient-enriched samples. Sediments exposed to enhanced levels of N exhibited the highest Chi a content while both N- and P-enriched samples showed increased photosynthetic yield. Very little depletion of nutrients in the water column was detected over time in the batch cultures except in the N+P-enriched treatments where nutrient values dropped to near-ambient levels.

The maximal effect of transurethral microwave thermotherapy (TUMT) for lower urinary tract symptoms (LUTS) of benign prostatic hyperplasia (BPH) occurs 3 to 6 months after treatment. In the acute period after TUMT, little change in symptoms, quality of life (QOL), and peak urinary flow rate (Qmax) is observed versus baseline. Some men may also develop acute urinary retention secondary to thermally induced edema. Recent reports suggest that early results of TUMT may be improved with concomitant use of either a temporary intraurethral prostatic bridge-catheter (PBC) or neoadjuvant and adjuvant alpha-blocker therapy. This report compares the results of these two adjunctive modalities directly. Methods. This nonrandomized retrospective comparison of results in 186 patients with LUTS of BPH is based on findings of three recently reported prospective clinical trials. All patients underwent targeted high-energy TUMT. Ninety-one patients received no further treatment (TUMT alone group), 54 an indwelling PBC for up to 1 month (TUMT + PBC group), and 41 neoadjuvant and adjuvant tamsulosin (0.4 mg daily) treatment (TUMT + tamsulosin group). The International Prostate Symptom Score (IPSS), QOL score, and Qmax were determined at baseline and 2 weeks after TUMT. Results. All three study groups experienced statistically significant improvements in mean IPSS and QOL score at 2 weeks versus baseline (P <0.0005). Nevertheless, the magnitude of improvement was greater in the TUMT + PBC group than the other two groups and greater in the TUMT + tamsulosin group than the TUMT alone group. A high proportion of the TUMT + PBC group (87.8%) attained a 50% or more IPSS improvement, compared with 4.5% of the TU MT alone group and none of the TU MT + tamsulosin group, and a similar pattern of between-group differences was noted with respect to the proportion of patients having 50% or more improvement in QOL score. The TUMT + PBC group was the only group to achieve significant Qmax improvement at 2 weeks compared with baseline. In the TUMT alone group, urinary retention 1 week or longer in duration occurred in 10 (11%) of 91 patients compared with 1 (2.4%) of 41 in the TUMT + tamsulosin group and none in the TUMT + PBC group. Early PBC removal was required in 11% of the TUMT + PBC group as a consequence of urinary retention secondary to clot formation or PBC migration. Conclusions. Both PBC placement and neoadjuvant and adjuvant alpha-blocker treatment are effective in alleviating symptoms and improving QOL during the acute period after TUMT. PBC usage also resulted in substantial early Qmax improvement. Either of these adjunctive modalities may be appropriate to consider in the treatment of TUMT patients during the early postprocedure recovery period. UROLOGY 54: 73-80, 1999.

J Do, JS; Her, AS Do, JS; Her, AS Mass transfer and current efficiency for the electrodeposition of silver in fluorosilicic acid solution JOURNAL OF APPLIED ELECTROCHEMISTRY English Article current efficiency; electrodeposition; fluorosilicic acid; mass transfer; silver POWDER The stripping and electrodeposition of silver in fluorosilicic acid solution are irreversible reactions as indicated by cyclic voltammetry. The rate constant for the intrinsic heterogeneous cathodic deposition of silver was obtained as k(C)(o) = 40.77 exp(1.88 - 29.43 E-C(o') and the diffusion coefficient of the silver ion in fluorosilicic acid solution as 5.17 x 10(-5) cm(2) s(-1). Theoretical calculations of the concentration of silver ion correlated well with experimental data. The relationship between the diffusion layer thickness and the stirring rate was also obtained. Increasing the stirring rate and temperature, and decreasing the current density and concentration of fluorosilicic acid, caused an increase in the current efficiency for silver deposition on graphite.

Hearts were perfused in the Langendorff mode and subjected to 23 min total global ischaemia and reperfused for 60 min. 2 Left ventricular function was assessed by means of an intra-ventricular balloon. High energy phosphates were measured by P-31-NMR spectroscopy. Intracellular levels of NAD were measured by capillary electrophoresis of perchloric acid extracts of hearts at the end of reperfusion. 3 Reperfusion in the presence of the PARS inhibitor 1,5 didroxyisoquinoline (ISO, 100 mu M) attenuated the mechanical dysfunction observed following 1 h of reperfusion; 27+/-13 and 65+/-8% recovery of preischaemic rate pressure product for control and 100 mu M ISO, respectively. 4 This cardioprotection was accompanied by a preservation of intracellular high-energy phosphates during reperfusion; 38+/-2 vs 58+/-4% (P<0.05) of preischaemic levels of phosphocreatine (PCr) for control and 100 mu M ISO respectively and 23 fl vs 31+/-3% (P<0.05) of preischaemic levels of ATP for control and 100 mu M ISO respectively. 5 Cellular levels of NAD were higher in ISO treated hearts at the end of reperfusion; 2.56+/-0.45 vs 4.76+/-1.12 mu moles g(-1) dry weight (P<0.05) for control and ISO treated. 6 These results demonstrate that the cardioprotection afforded by inhibition of PARS activity with ISO is accompanied by a preservation of high-energy phosphates and cellular NAD levels and suggest that the mechanism responsible for this cardioprotection may involve prevention of intracellular ATP depletion.

Children aged 0-14 years with leukaemia were matched on age and sex to controls selected from birth records. Case ascertainment was virtually complete and 121 (92%) of 131 eligible case families took part. The participation rate among the 303 first-choice eligible controls was 69%. Home interviews and serological tests were conducted. Adjusted relative risks were estimated by logistic regression. There was an increased risk of leukaemia in relation to reported influenza infection of the child during the first year of life (adjusted odds ratio 6.8, 95% confidence interval 1.8-25.7). This could be a chance finding due to multiple comparisons, and it should be tested elsewhere. Some key variables relevant to Greaves' hypothesis were not associated with B-cell precursor acute lymphoblastic leukaemia (numbers of infections and vaccinations, firstborn status, attendance at preschool groups), although a smalt effect could not be ruled out with a study of this size. Leukaemia risk was higher among children in poorer social circumstances, and this was true for all eligible children as well as for the participants.

Hybrid GPS plus GLONASS GPS SOLUTIONS English Article Data Processing; GNSS; Hybrid System; Frequency Diversity; Signal Frequency The hybridization of GPS with GLONASS has formed a first stage in GNSS development. We examine the performance of the hybrid system in the position domain for both code and carrier phase cases. Several major differences exist between GPS and GLONASS; most significant is GLONASS's signal frequency diversity, which can lead to measurement bias, particularly so when a pair of receivers are operating at different temperatures. Unless signal frequency diversity is addressed either on-receiver or at the data processing stage, positioning errors can occur at the centimeter level. We outline the difficulties of combining observations from the two systems and discuss how these may be overcome. (c) 1999 John Wiley & Sons, Inc.

J Donaghy, M; Kennett, R Donaghy, M; Kennett, R Varying occurrence of vocal cord paralysis in a family with autosomal dominant hereditary motor and sensory neuropathy JOURNAL OF NEUROLOGY English Article hereditary motor and sensory neuropathy type IIC; vocal cord paralysis; abducens nerve palsy CHARCOT; MARIE; TOOTH A white British family with the axonal form of hereditary motor and sensory neuropathy (HMSN, type II) contained one member who developed a recurrent laryngeal nerve palsy at the age of 41 years, in addition to 4 years of symptomatic polyneuropathy and an abducens nerve palsy. Neither of the other family members (the mother and sister) with electrophysiologically confirmed polyneuropathy had any neuropathic symptoms in the limbs or laryngeal or respiratory muscle involvement. An autosomal dominant pattern of inheritance is likely. This is a second report of this rare form of HMSN (type IIC) in which there is associated laryngeal or respiratory muscle weakness. This family differs from the two previously reported pedigrees in which laryngeal or diaphragm weakness had commenced within the first two decades. The discovery of asymptomatic family members attests to the diagnostic value of clinical and electrophysiological study of first-degree relatives when laryngeal or bulbar symptoms develop in the context of chronic axonal polyneuropathy. HMSN type IIC should be distinguished from the more common forms of HMSN - type IIA, in which axonal polyneuropathy is restricted to the limbs, and type IIB, which is of early onset and associated with foot ulceration.

The configuration considered is that of a circular ejector with single element primary nozzle. The Favre-filtered Navier-Stokes equations with a subgrid model are used to simulate the large scale structure. The high-order dispersion relation-preserving scheme is used to minimize dispersion and dissipation errors. Special boundary treatments are adopted for inflow, outflow, and solid walls to eliminate nonphysical reflections. Results show the growth of the disturbances, the formation of weak shock-cell structures, and the propagation of acoustic waves.

J Dorrance, HR; Oien, K; O'Dwyer, PJ Dorrance, HR; Oien, K; O'Dwyer, PJ Effects of laparoscopy on intraperitoneal tumor growth and distant metastases in an animal model SURGERY English Article ABDOMINAL-WALL METASTASES; ASSISTED COLECTOMY; SITE METASTASES; GALLBLADDER CANCER; SURGERY; ADENOCARCINOMA; RECURRENCE; COLON; LYMPHADENECTOMY; CHOLECYSTECTOMY Background and aims. Laparoscopic surgery for colorectal cancer is currently being evaluated in humans. The aim of this study was to examine the effect of laparoscopy on intraperitoneal tumor growth and distant metastases in an animal model. We also examined the effect of combining laparotomy with laparoscopy and on infusing the peritoneal cavity with normal saline solution (NaCl), crater; and sodium hypochlorite after laparoscopy on intraperitoneal tumor growth. Material and methods. Female Fischer rats were given MtLn3 adenocarcinoma cells by intraperitoneal injection to produce intraperitoneal tumor growth and by tail vein injection to produce lung metastases. A pneumoperitoneum was then induced to a pressure of 8 mm Hg with carbon dioxide (CO2), helium, or room air After this, animals were allowed to either recover or underwent laparotomy or infusion of NaCl, water, or sodium hypochlorite before recovery, depending on the experiment. At 21 days all animals were killed and intraperitoneal tumor growth was assessed by counting the number of peritoneal and serosal nodules and by weighing the omental pad of tumor Lung metastases were assessed by counting the number of metastases after fixation. Results. Laparoscopy caused a marked intraperitoneal dissemination of tumor with a median of 17 (10 to 20) peritoneal and serosal nodules for CO2, 19.5 (12.5 to 25) for helium, and 15.0 (9.9 to 1.77) for room air compared with 0 (0 to 1) for controls (P <.0001). The weight of omental tumor was also significantly increased (P <.02) in the CO2, helium, and room air groups. Infusion with NaCl, water, or sodium hypochlorite had no effect on tumor dissemination after laparoscopy. The combination of laparoscopy and laparotomy caused a significant reduction (P <.05) in the number of peritoneal nodules but had no significant effect on omental tumor growth. Laparoscopy also had no effect on the number of pulmonary metastases induced compared with controls. Conclusions. This study shows that laparoscopy promotes intraperitoneal dissemination of tumor. This effect is independent of the insufflating gas used and is not affected by use of a cytotoxic agent. The use of gasless laparoscopy should be encouraged by those undertaking curative laparoscopic surgery for colorectal cancer.

More than 100 hydrocarbons and oxygenated hydrocarbons were tentatively identified and quantified. Gasoline-vapor and whole-gasoline profiles could be distinguished from the other profiles by high concentrations of the C-5 and C-6 saturated hydrocarbons. The vehicle emission profile was similar to the whole-gasoline profile, with the exception of the unsaturated and aromatic hydrocarbons, which were present at higher concentrations in the vehicle emission profile. High levels of the C-2-C-4 saturated hydrocarbons, particularly n-butane, were characteristic features of the petroleum refinery emissions. The smelter and cast iron factory emissions were similar to the refinery emissions; however, the levels of benzene and toluene were greater in the former two sources. The LPG and natural gas emissions contained high concentrations of n-butane and ethane, respectively. The NMOC source profiles for Cairo were distinctly different from profiles for U.S. sources, indicating that NMOC source profiles are sensitive to the particular composition of petroleum fuels that are used in a location.

J Douglas, MR; Mallonee, S; Istre, GR Douglas, MR; Mallonee, S; Istre, GR Estimating the proportion of homes with functioning smoke alarms: A comparison of telephone survey and household survey results AMERICAN JOURNAL OF PUBLIC HEALTH English Article RESIDENTIAL-FIRE INJURIES; RISK-FACTORS; HEALTH; SURVEILLANCE Administering questionnaires by telephone has become an increasingly acceptable and widely used means of doing health research.(1) Telephone surveys have many advantages over in-person surveys. They are usually less expensive,(1-5) and they minimize sampling error when the sample is drawn from random-digit dialing.(1,6,7) Telephone surveys allow for timely data collection for states and subgroups of the population.(2-4,8) The main disadvantage of telephone surveys has been the potential for sampling bias(2,9) and variable estimates of behavioral factors caused by excluding households not accessible by telephone. According to the US census, 95% of US households and 91% of Oklahoma households had telephones in 1990. To determine the proportion of households with functioning smoke alarms in a low-income area of Oklahoma City with a high rate of residential fire-related injuries,(10) we conducted a targeted random telephone survey; to validate the telephone survey, we conducted a retrospective random household survey. The purpose of the survey was to establish a baseline rate for use in evaluating a large smoke-alarm giveaway program in this high-risk area.

The calculation is offerred as a particular application of a general technique developed earlier for obtaining heat-kernel coefficients on a bounded generalized cone which involves writing the sphere and ball xi-functions, and coefficients, in terms of Barnes xi-functions and generalized Bernoulli polynomials. Functional determinants are computed. Spinors are also treated by the general method.

The tropical N-cycle is traced from pre-disturbance conditions through the phases of disturbance, highlighting major differences between tropical and temperate systems that might influence development strategies in the tropics. Analyses suggest that tropical freshwaters are more frequently N-limited than temperate zones, while tropical marine systems may show more frequent P limitation. These analyses indicate that disturbances to pristine tropical lands will lead to greatly increased primary production in freshwaters and large changes in tropical freshwater communities. Increased freshwater nutrient flux will also lead to an expansion of the high production, N- and light-limited zones around river deltas, a switch from P- to N-limitation in calcareous marine systems, with large changes in the community composition of fragile mangrove and reef systems. Key information gaps are highlighted, including data on mechanisms of nutrient transport and atmospheric deposition in the tropics, nutrient and material retention capacities of tropical impoundments, and N/P coupling and stoichiometric impacts of nutrient supplies on tropical aquatic communities. The current base of biogeochemical data suggests that alterations in the N-cycle will have greater impacts on tropical aquatic ecosystems than those already observed in the temperate zone.

J Doyle, V; Virji, S; Crompton, M Doyle, V; Virji, S; Crompton, M Evidence that cyclophilin-A protects cells against oxidative stress BIOCHEMICAL JOURNAL English Article antisense oligodeoxynucleotides; cardiomyocytes; cyclosporin A MITOCHONDRIAL PERMEABILITY TRANSITION; CYCLOSPORINE-A; MESSENGER-RNA; INORGANIC-PHOSPHATE; REPERFUSION INJURY; INDUCED DAMAGE; PORE; HEPATOCYTES; INVOLVEMENT; CLONING Cyclophilin-A is the cytosolic isoform of a family of peptidyl-proline cis-rr uns-isomerases that bind cyclosporin A. This study investigates the role of cyclophilin-A in necrotic cell death, induced by chemical ischaemia and by t-butylhydroperoxide. An 18-mer antisense phosphorothioate oligodeoxynucleotide was used to target a translated region of cyclophilin-a mRNA in rat neonatal cardiomyocytes. After a 24 h exposure to the oligonucleotide, the amount of cyclophilin-A in the cells was decreased by at least 93% as judged bq immunological and enzymic criteria. For the enzyme assays, peptidyl proline cis-trans-isomerase activity was measured fluorimetrically in small (10 mu l) volumes of cell extract. Immunoblots were developed with a polyclonal anti-cyclophilin-A antibody after sample isoelectric focusing and SDS/PAGE. Cyclophilin-A suppression had no effect on cyanide-plus-3-deoxyglucose-induced cell death. However, cyclophilin-A-suppressed cells were markedly more sensitive to t-butylhydroperoxide. Cyclosporin A conferred some resistance to the peroxide in both types of cell, bur protection was greater in cyclophilin-A-suppressed cells, where cyclosporin A increased the survival time 2-fold. It is concluded that two cyclophilin isoforms are involved, in quite different ways, in peroxide-induced cell death. Cyclophilin-A has a protective role. Another isoform, possibly mitochondrial cyclophilin-D, has a deleterious cole, such that blockade by cyclosporin A leads to protection.

Design: National Diet and Nutrition Survey: cross-sectional survey of a nationally representative population of men and women aged 65y and over. Setting: Mainland Great Britain Subjects: 1268 participants (651 men and 617 women) who provided both dietary intake and blood biochemistry. 986 were living in private households and 282 were living in residential or nursing homes. Results: Intakes of alcohol, vitamin C, protein, haem and non-haem iron and fibre were positively associated with iron status. Consumption of meat, poultry and fish were positively associated with six measures of iron status, and vegetables and potatoes with four measures. Calcium, dairy foods and tea generally had a negative association with most measures of iron status. Conclusions: A varied diet containing meat, poultry and fish, vegetables and fruit, with a moderate intake of alcohol will make a positive contribution to the iron status of elderly people.

Differentiation induction is a new approach taking into account that malignant glioma cells share many features with immature glial progenitor cells that are capable of terminal differentiation. The concept of differentiation therapy is currently evaluated for several pediatric malignancies with or without multimodal standard therapy. Valproic acid (VPA) is a branched chain fatty acid that is able to inhibit proliferation of neuroectodermal cells and to induce these cells along neuronal or glial lineage. Preclinical studies have shown that VPA inhibits growth of human and rodent glial tumor cells in vitro and induces a distinct mature glial phenotype, In addition, growth of human neuroblastoma cells is inhibited in vitro and in vivo and exhibits marked evidence of differentiation. Treatment of neuroblastoma and glioma cells with VPA was accompanied by changes of surface molecule expression that enhance immunogenicity and reduce their capability to metastasize. The antitumoral effects observed in preclinical studies were reached at concentrations that are readily achieved in patients treated with VPA for epilepsy. Epilepsy patients receiving VPA have significantly enhanced hemoglobin F levels, supporting the hypothesis that nontoxic levels of VPA can induce cellular differentiation.

This correlation forms the basis for developing the PPCO method which, in principle, can determine spins, parities and multipolarities. The method is particularly useful when gamma rays are produced in heavy ion reactions, ensuring a high spin alignment. The paper presents an experimental test of the PPCO method and the results suggest, that this method can be applied with success in modern gamma-ray spectroscopy in which a large number of detectors are sensitive to the polarization (e.g. the CLOVER detectors). When this method is combined with an angular correlation analysis, the number of the possibilities concerning spins, parities and multipolarity sequences can be reduced significantly.

J Drouet, JL; Bonhomme, R Drouet, JL; Bonhomme, R Do variations in local leaf irradiance explain changes to leaf nitrogen within row maize canopies? ANNALS OF BOTANY English Article 3D plant architecture; horizontal gradients in leaf nitrogen; leaf irradiance; leaf nitrogen content per unit area; maize; nitrogen partitioning; nitrogen remobilization; virtual plant; Zea mays L. LUCERNE CANOPY; USE EFFICIENCY; CARBON GAIN; C-3 PLANTS; PHOTOSYNTHESIS; LEAVES; RADIATION; DENSITY; AGE; ACCLIMATION Numerous studies have dealt with the relationship between leaf nitrogen content and leaf irradiance. However, most of them refer to dense stands presenting reduced horizontal heterogeneity of foliage distribution. Both gradients of leaf nitrogen and leaf irradiance related to canopy depth are significant under such conditions, and modelling radiative exchange using a turbid-medium analogy and dividing the canopy into vegetation layers is sufficient. Conversely, row crops such as maize are characterized by strong horizontal heterogeneity of foliage distribution and the one-dimensional (1D) approach may be unsuitable. We thus modelled the three-dimensional (3D) geometry of maize canopies with varying densities and at different developmental stages using plant digitizing under field conditions. The nitrogen content per unit area of each leaf part was obtained subsequently by nitrogen analysis. We next calculated radiative exchange using a 3D volume-based approach within the canopies in order to estimate local leaf irradiance on a daily integration scale. Vertical gradients in leaf nitrogen content per unit area observed in dense stands during the vegetative phase corresponded largely to those reported in the literature. We also identified significant gradients in nitrogen content along the leaves, which had not before been clearly demonstrated. Our study shows that local light climate during plant development plays a major role in leaf nitrogen distribution and remobilization. Moreover, brutal plant thinning involves rapid changes in leaf nitrogen partitioning. It is concluded that taking account of the 3D heterogeneity of nitrogen and irradiance distribution may have implications for modelling crop photosynthesis and production.

J Druhan, JP; Wilent, WB Druhan, JP; Wilent, WB Effects of the competitive N-methyl-D-aspartate receptor antagonist, CPP, on the development and expression of conditioned hyperactivity and sensitization induced by cocaine BEHAVIOURAL BRAIN RESEARCH English Article N-methyl-D-aspartate; cocaine; excitatory amino acid AMPHETAMINE BEHAVIORAL SENSITIZATION; RAT-BRAIN MEMBRANES; CHANNEL COMPLEX; OPEN-FIELD; STRESS; NMDA; MK-801; ACQUISITION; LOCOMOTOR; AMYGDALA This study used novel behavioral measures to examine the effects of the competitive N-methyl-D-aspartate (NMDA) receptor antagonist, CPP, on the development and expression of conditioned hyperactivity and sensitization produced with cocaine. The first experiment confirmed that horizontal locomotor activity measured in the central zone of an activity enclosure could be increased by 10.0 mg/kg cocaine. This increased activity showed sensitization after repeated cocaine injections, and it could be conditioned to the test environment. Subsequent experiments demonstrated that CPP (0.2 and 0.4 nmol, icv) could block the development, but not the expression, of conditioned hyperactivity and sensitization in the central zone. These findings confirm that NMDA receptors are critically involved in the development of conditioned hyperactivity and sensitization, but indicate that such receptors may not be necessary for the expression of these neurobehavioral adaptations.

(1998) J. Biol. Chem. 273, 10933-10938]. The refolding efficiency was found to increase with decreasing RrF(1)alpha concentrations and required high concentrations of MgATP, saturating approximate to 60% when 50 mu g protein.mL(-1) were refolded in presence of 50 mM MgATP. Size-exclusion HPLC of such refolded RrF(1)alpha revealed a 50-60% decrease in its aggregated form and a parallel appearance of its monomeric peak. RrF(1)beta refolded under identical conditions appeared almost exclusively as a monomer. This procedure enabled the isolation of large amounts of a stable RrF(1)alpha monomer, which stimulated the restoration of ATP synthesis and hydrolysis much more efficiently than the refolded cu mixture, and bound ATP and ADP in a Mg-dependent manner. Incubation of both RrF(1)alpha and beta monomers, which by themselves had no ATPase activity, resulted in a parallel appearance of activity and assembled alpha(1)beta(1)-dimers, but showed no formation of alpha(3)beta(3)-hexamers. The RrF(1)-alpha(1)beta(1)-ATPase activity was, however, very similar to the activity observed in isolated native chloroplast CF1-alpha(3)beta(3), indicating that these dimers contain only the catalytic nucleotide-binding site at their alpha/beta interface. Their inability to associate into an alpha(3)beta(3)-hexamer seems therefore to. reflect a much lower stability of the noncatalytic RrF(1) alpha/beta interface.

JOURNAL OF ENVIRONMENTAL BIOLOGY English Article lichens; lead accumulation; heavy metals HEAVY-METALS; PLANTS Studies on lead accumulation in lichens were performed at twelve different sites in and around Faizabad city of Uttar Pradesh. The concentration of lead-in lichens decreases with increasing distance from the source of pollution. Lead accumulation was more in lichens collected from higher vertical position than that of lower vertical position. The lead content also varied among the lichen species. The highest concentration of lead was found in Dirinaria papillulifera on the Faizabad-Rae Bareli Road.

J Dubey, SP; Garap, JP Dubey, SP; Garap, JP Paediatric tracheostomy: an analysis of 40 cases JOURNAL OF LARYNGOLOGY AND OTOLOGY English Article tracheostomy; child; post-operative complications PEDIATRIC TRACHEOTOMY Tracheostomy in the paediatric patient has been associated with significant morbidity and mortality compared to that in the adult. A retrospective analysis was made of 40 patients up to the age of 12 years having tracheostomies. Upper airway obstruction made up the commonest (32 patients, or 80 per cent) indication for paediatric tracheostomy in our series where males slightly outnumbered females. The majority (31 patients, or 77.5 per cent) underwent the operation under general anaesthesia with endotracheal intubation. Thirty-four (85 per cent) patients underwent 'planned' tracheostomies and six (15 per cent) underwent 'crash' procedures. Thirteen (32.5 per cent) patients were under the age of one year when tracheostomies were performed. The maximum duration of tracheostomies was between one week to within a month and after one month to within three months; each containing 11 (27.5 per cent) patients. Sixty-four different surgical procedures were performed on these patients in which laryngoscopy and bronchoscopy were the commonest procedures. Nine (22.5 per cent) had early post-operative and 14 (35 per cent) had late post-operative complications. Among these 40 children with tracheostomies, one (2.5 per cent) died due to a tracheostomy-related cause and 10 (25 per cent) due to the primary disease process itself. Tracheostomies performed to provide access for general anaesthesia for other surgical procedures were associated with a better prognosis.

The multilayers of the first series are composed of a conventional stacking of Py and Cu layers and the GMR is studied as a function of the Cu thickness for a constant Py thickness. The multilayers of the second series are composed of Py/Cu/Py trilayers uniformly distributed along the filament and separated from each other by thick Cu layers. For this second series, magnetic and GMR properties were investigated as a function of the Py layer thickness and our magnetization measurements demonstrate that, for Py layers thinner than about 90 nm, the magnetic moments of the two Py layers of a trilayer are approximately antiparallel at zero field. Analysis of the GMR data using the Valet-Fert model allows us to estimate that the spin diffusion length in Py, L-sf((PY)) , is between 3.3 and 5.3 nm. [S0163-1829(99)06125-1].

J Duck, SC; Rapaport, R Duck, SC; Rapaport, R Long-term treatment with GHRH [1-44] amide in prepubertal children with classical growth hormone deficiency JOURNAL OF PEDIATRIC ENDOCRINOLOGY & METABOLISM English Article GHRH [1-44]; growth hormone deficiency; treatment THERAPY A cohort of 20 GH deficient prepubertal patients were treated with GHRH [1-44] 10 mu g/kg or 20 mu g/kg twice daily for up to four years (5 patients). GHRH treatment resulted in sustained improvement in height velocity. The mean prepubertal height velocity was 3.57 +/- 1.05 cm/yr pretreatment; 8.49 +/- 1.45 cm/yr at year 1; 6.86 +/- 1.45 cm/yr at year 2; 6.22 +/- 0.74 cm/yr at year 3; and 6.16 +/- 0.97 cm/yr at year 4, IGF-I levels increased and remained within normal range. The difference between the children's and the parents' Ht SD scores significantly diminished from a pretreatment difference of -2.43 to -0.48 after four years of treatment. No adverse effects were noted during treatment. We conclude that twice-daily GHRH [1-44] treatment in a small group of prepubertal GH deficient children resulted in sustained improvement in height and growth velocity, and achieved height SDS approaching closely those of their parents.

J Dujella, A Dujella, A A proof of the Hoggatt-Bergum conjecture PROCEEDINGS OF THE AMERICAN MATHEMATICAL SOCIETY English Article Fibonacci numbers; property of Diophantus; simultaneous Pellian equations; linear form in logarithms; Baker-Davenport reduction procedure It is proved that if k and d are positive integers such that the product of any two distinct elements of the set {F-2k, F2k+2, F2k+4, d} increased by 1 is a perfect square, then d has to be 4F(2k+1)F(2k+2)F(2k+3). This is a generalization of the theorem of Baker and Davenport for k = 1.

J Dumay, E; Laligant, A; Zasypkin, D; Cheftel, JC Dumay, E; Laligant, A; Zasypkin, D; Cheftel, JC Pressure- and heat-induced gelation of mixed β-lactoglobulin/polysaccharide solutions:: scanning electron microscopy of gels FOOD HYDROCOLLOIDS English Article high pressure; mixed gels; beta-lactoglobulin; pectins; alginate; phase separation ENZYME-TREATED CASEINS; WHEY PROTEINS; RHEOLOGY; POLYSACCHARIDES; LACTOGLOBULIN; EMULSIONS This study concerns the microstructure of pressure-induced gels (P-gels, 450 MPa, 25 degrees C, 30 min) of mixed beta-lactoglobulin/anionic polysaccharide solutions (12% w/w protein, pH 7.0, plus 0.1-1% w/w sodium alginate, low methoxy pectin or high methoxy pectin). Mixed biopolymer solutions were compatible at ambient temperature and atmospheric pressure in the concentration range studied. Scanning electron microscopy of mixed P-gels from 12% protein-0.1% polysaccharide (PS) solutions revealed microalveoles with a honeycomb structure, suggesting that pressure promoted the formation of water in water emulsion with two distinct phases of different protein and PS concentrations. Increasing PS concentration from 0.1 to 1% (w/w) progressively converted the micro-alveolated structure of P-gels into a coarser porous structure with large pores and pillars", and protein microparticles located in the pores. The trend to phase separation and protein microparticulation increased with PS concentration and varied in the following decreasing order: ALG much greater than LMP much greater than HMP. Phase separation phenomena and the resulting P-gel microstructure probably depend on the net negative charges carried by the PS and on the imparted solution viscosity. Heating the mixed protein-polysaccharide solutions at 87 degrees C for 40 min also induced phase separation, porous structures and protein microparticulation. The results suggest that phase separation in the presence of an anionic polysaccharide is triggered by beta-lactoglobulin unfolding and/or aggregation. (C) 1999 Elsevier Science Ltd.
