The candidate oncogene bcl-3 was discovered as a translocation into the immunoglobulin alpha-locus in some cases of B-cell chronic lymphocytic leukaemias. The protein Bcl-3 contains seven so-called ankyrin repeats. Similar repeat motifs are found in a number of diverse regulatory proteins but the motifs of Bcl-3 are most closely related to those found in I kappa B proteins in which the ankyrin repeat domain is thought to be directly involved in inhibition of NF-kappa B activity. No biological function has yet been described for Bcl-3, but it was noted recently that Bcl-3 interferes with DNA-binding of the p50 subunit of NF-kappa B in vitro. Here we demonstrate that Bcl-3 can aid kappa B site-dependent transcription in vivo by counteracting the inhibitory effects of p50/NF-kappa B homodimers. Bcl-3 may therefore aid activation of select NF-kappa B-regulated genes, including those of the human immunodeficiency virus. [less ▲]

This report investigated the distribution of serum zinc and the factors determining serum zinc concentration in a large random population sample. The 197 participants (959 men and 1018 women), 20-80 years old, constituted a stratified random sample of the population of four Belgian districts, representing two areas with low and two with high environmental exposure to cadmium. For each exposure level, a rural and an urban area were selected. The serum concentration of zinc, frequently used as an index for zinc status in human subjects, was higher in men (13.1 µmole/L, range 6.5-23.0 µmole/L) than in women (12.6 µmoleL, range 6.3-23.2 µmole/L). In men, 20% of the variance of serum zinc was explained by age (linear and squared term, R=0.29), diurnal variation (r=0.29), and total cholesterol (r=0.16). After adjustment for these covariates, a negative relationship was observed between serum zinc and both blood (r= -0.10) and urinary cadmium (r= -0.14). In women, 11% of the variace could be explained by age (linear and squared term, R = 0.15), diurnal variation in serum zinc (r=0.27), creatinine clearance (r= -0.11), log y-glutamyltranspeptidase (r= 0.08), cholesterol (r= 0.07), contraceptive pill intake (r= -0.07), and log serum ferritin (r=0.06). Before and after adjustment for significant covariates, serum zinc was, on average, lowest in the two districts where the body burden of cadmium, as assessed by urinary cadmium excretion, was highest. These results were not altered when subjects exposed to heavy metals at work were excluded from analysis. [less ▲]

P300 is a late component of evoked potential which meet special relevance to the study of cognitive processes. P300 indexes categorization processes and the context updating of memory. Its latency reflects the stimulus evaluation time, and P300 amplitude is related to some psychological variables such as expectancy, attention and stimulus significance. In this review, clinical correlation between P300 components and mental diseases are reported, especially dementia, schizophrenia and depression. Delayed P300 latency has been found in Alzheimer disease and in other forms of dementia. Reduced P300 amplitude as well as altered topography has been reported in schizophrenia. In depression, reduced P300 amplitude has been related with longer reaction time. Unfortunately, the diagnosis utility of P300 seems limited. The authors also propose an overview of the actual knowledge on neurobiological findings in the generation of the P300 wave. Anatomical data point out the importance of the limbic system, more specifically, of the hippocampus and the locus coeruleus, in generating and modulating P300 wave. Data from the literature on the psychopharmacological modifications induced by cholinergic, catecholaminergic and other agents, are reviewed. Although the dopaminergic and noradrenergic systems are of some importance, these data emphasise the importance of the cholinergic system for the generation and modulation of P300 amplitude and latency. The value and interpretation of these neurobiological and clinical findings are discussed. [less ▲]

In a pharmaceutical form also containing carbromal, meprobamate could not be quantified selectively by classical methods described in pharmacopoeias due to a significant interference from carbromal. Consequently, reversed-phase HPLC methods have been developed to separate the two active ingredients using indirect photometric detection to visualize and determine meprobamate which has very poor chromophoric properties. Different parameters influencing the sensitivity of the indirect response, such as the nature of the highly absorbing compound added to the mobile phase (the marker) as well as the methanol content and the pH of this phase, have been studied. Two chromatographic systems containing benzoic acid or cinnamic acid as the marker, have been optimized and validated. Good linearity and reproducibility have been obtained with both systems but the cinnamic acid method has the advantage that meprobamate and carbromal can be determined simultaneously at 273 nm.

We have used in situ hybridization to investigate the expression of TNF-alpha genes by thymic cells during fetal development in mice. In 14-day-old fetal thymuses, very scarce cells produce TNF-alpha mRNA. A second phase of cytokine gene expression starts on day 16. The density of positive cells progressively increases up to day 20. Thymuses at 15 days of gestation and after birth do not express detectable cytokine mRNA. In an attempt to identify the nature of the TNF-alpha mRNA-producing cells, acid phosphatase activity, which is characteristic of the macrophage lineage, was studied in the same thymuses. Acid phosphatase-positive cells only appear on day 15. Their frequency increases up to birth. However, no correlation can be established between acid phosphatase--and TNF alpha mRNA--positive cells. The results indicate that a small subset of thymic cells is responsible for TNF-alpha mRNA production during ontogeny: These cells are not yet identified. The possible role of TNF-alpha in thymic ontogeny is discussed. [less ▲]

IGF-I and II genes expression has been localized by in situ hybridization in testis and epididymis of immature hypophysectomized rats treated in vivo with either pFSH, hLH, bGH, hPRL or with saline. IGF-I mRNA expression was found in both Sertoli and Leydig cells after treatment with either FSH or LH. IGF-I mRNA was highly expressed in germ cells after FSH stimulation and to a lesser extent after GH or LH treatments. However, its expression was very low in hypophysectomized control or PRL treated rats. IGF-I mRNA was also expressed in stromal cells of epididymis after LH treatment and to a lesser extent after GH stimulation. In contrast, IGF-II mRNA expression was detected in all testicular cell types whatever the hormonal treatment (FSH, LH, GH, PRL). For each hormonal treatment testicular sections were examined after immunohistochemical staining with specific antisera against IGF-I and IGF-II. Both in situ hybridization and immunohistochemical data were examined in order to determine the testicular sites of synthesis of IGF-I and IGF-II. [less ▲]

A seasonal one-and-a-half-dimensional (1 1/2-D) energy-balance climate model including a detailed sea ice calculation and an interactive albedo formulation has been developed and is used to investigate the faint young sun climatic paradox. This model is shown to reproduce the present climate and sea ice observations. In spite of its greater complexity, its behavior is globally similar to simple energy-balance models with highly parameterized ice-albedo feedback used in previous studies of this question. It is found that when the solar luminosity drops by more than about 5% below its present value, the ice albedo feedback causes a global irreversible glaciation. Several sensitivity experiments show that the value of the critical solar constant and associated global surface temperature are only little sensitive to the set of model parameters describing the ice and snow albedo and meridional heat transport. In contrast, the absence or polar location of the continental mass introduce a nearly 10% decrease of the critical luminosity. The minimum level of atmospheric CO2 needed to prevent a global glaciation through enhanced greenhouse warming is calculated as a function of the solar luminosity. A 30% drop in solar output requires a 2 x 10(4)-fold increase in atmospheric CO2, an unacceptably large value. However, in the absence of continents, a carbon dioxide partial pressure of 2000 times the present level is found to be sufficient to stabilize the climate. The effects of a reduced continental area, paleogeographic changes and higher CO2 greenhouse effect combine to ensure a larger stability of the non-frozen configuration. Their cumulated and interactive effects may be able to solve the young sun paradox. [less ▲]

The sigma-transformation is a widely used coordinate change that maps the actual depth-varying sea onto a computational domain, the depth of which is constant. The advantages of this technique are numerous. It permits an efficient use of computer resources, a simple treatment of the surface and bottom boundary conditions, and an accurate representation of the bathymetry. However, if the range of the depth is too large, or when the depth varies too rapidly, as in the shelf break region, it may be shown that the sigma-transformation leads to severe numerical errors. In the application of GHER's three-dimensional model to the Western Mediterranean, the occurrence of those numerical errors is avoided by the introduction of a two-fold sigma-coordinate system in the deep sea.

The purpose of this study was (1) to evaluate the technical and methodological problems associated with invasive haemodynamic measurements in unsedated cattle; (2) to assess the reproducibility of such measurements both within and between days; and (3) to compare the values with those previously reported. Twenty-one healthy calves, aged from 5.5 to 12 months, were studied. The central venous, the right ventricular, the pulmonary arterial, the pulmonary capillary wedge and the systemic arterial pressures were obtained by means of fluid-filled catheters, and the cardiac output was measured by the thermodilution technique. The heart rate, the stroke volume, the pulmonary and systemic vascular resistances and the pulmonary and systemic ventricular workloads were calculated. An adverse reaction, consisting of severe pulmonary hypertension, tachycardia, tachypnoea and transient weakness, occurred in 7 calves during the catheterization procedures. Such a reaction might be due to a local reflex induced by stimulation of mechano-receptors by the catheter tip. It should be avoided by reducing the manipulation of the catheter as much as possible and by inflating the tip of the balloon when moving it forwards. A comparison of the vascular pressures with those previously reported was difficult because of methodological or technical limitations, such as, for instance, a lack of standardization of the baseline. The reproducibility of the haemodynamic measurements obtained was satisfactory, in contrast to previous studies performed in conscious animals. This was attributed to our animals being better trained to the experimental conditions and emphasizes the importance of reducing mental stress in obtaining reliable haemodynamic measurements in unsedated and potentially uncooperative animals.

The synthesis of various [F-18]fluoroaromatic aldehydes using activated nitro precursors and aminopolyether supported nucleophilic substitution with F-18(-) is reported. These radiolabelled fluorinated aldehydes (radiochemical yields: 50-75%) are powerful key intermediates leading after treatment with NaBH4 and SOBr2 (SOCl2) to further active intermediates for example substituted [F-18]fluorobenzyl bromides (yields 30-50% EOB). These benzaldehydes and bromides are particularly useful for the preparation of new radiopharmaceuticals (e.g. fluorotroprapride, fluorodexetimide) either by reductive amination or by aromatic N-alkylation. The preparation of various amino acids in D, L (50:50) or enriched L form by asymmetric synthesis is also possible (e.g. L-6-[F-18]fluorodopa, L-4-[F-18]fluoro-m-tyrosine). It can be anticipated that the F-18-labelled fluoroaldehydes will find widespread application in radiopharmaceutical chemistry. [less ▲]

The expert-system approach is well suited to manage complexes heating systems, with various energy sources and different possible strategies of heating or cooling. A specific computer tool is applied on the solar-assisted heat pump system of Fondation Universitaire Luxembourgeoise in Arlon. It is developed around a list of rules of the type : "if…then.." and the code is written in Prolog language. The main difficulty of implementing such tool is the managing of time, because every sensor or actuator reacts in real time and a decision has first to be tested and validated before issuing on-line action on the system. The main advantage of the approach is that expert-system can very easily encapsulate the experimental knowledge of the heating system manager, simply by adding some rules in the rule base. [less ▲]

A preliminary ''small-perturbation'' analytical study of a non-dissipative idealized model of the Algerian Current is made, with the aim of identifying major characteristic scales and investigating the reality of possible classical instability mechanisms. The simple configuration is shown to be stable, from a linear perturbation point of view. The GHER 3D Primitive Equation Model is then applied to a more realistic investigation of the Algerian Current. The GHER model is non-linear, three-dimensional, with turbulent closure, mode splitting and a sigma-Coordinate formulation. The numerical simulation shows the development and mature pattern of the instability in excellent agreement with the observations. The relative importance of the existence of a coastal boundary layer, the nature of the initial perturbation, baroclinic and non-linear effects on the instability mechanism is discussed. [less ▲]

BACKGROUND. Anaemia is a frequent finding in patients with cancer and may be due to different causes, including blunted erythropoietin production. MATERIALS AND METHODS. In a pilot study, we administered recombinant human erythropoietin (rHuEPO) to twelve patients with solid tumours and secondary anaemia. rHuEPO was given subcutaneously 5 d per week at escalating doses (75 to 150 U/kg per day): the aim of treatment was a Hb level > or = 10 g/dl without blood transfusion. We evaluated endogenous EPO production through serum EPO levels and erythroid marrow activity by means of serum transferrin receptor (TfR). RESULTS. Six out of 12 subjects had defective endogenous EPO production. All patients but two responded to treatment with steady increases in Hb levels above 10 g/dl, and the median dose of rHuEPO required for correction of anaemia was 75 U/kg. Response was associated with an early increase in serum TfR. Six patients developed functional iron deficiency and required iron supplementation to obtain response. Treatment improved functional ability in 4/10 responders. CONCLUSIONS. Subcutaneous rHuEPO can stimulate erythroid marrow activity in cancer anaemia, even in patients with advanced disease, and marrow response can be adequately monitored by serum TfR. Functional iron deficiency as a cause of nonresponse to rHuEPO is frequent in these patients and may require parenteral iron administration. Although erythropoietin can improve the anaemia of cancer, the decision to treat should be individualised for each patient, looking more at the quality of life and cost-effectiveness than at cosmetic increases in the haemoglobin level.

The cardiomyoplasty procedure involves the use of a transformed skeletal muscle to augment cardiac pump function or to substitute for the heart after parietal resection. This study of the intramuscular vascularization of latissimus dorsi was carried out in order to establish the relationship between the dominant thoracodorsal blood supply and the distal supply issued from the intercostal and lumbar arteries. This data is mandatory for the safe manipulation of the muscle flap during cardiomyoplasty. Thirty human latissimus dorsi flaps were carefully studied. We confirmed anatomically as well as angiographically previous macroscopic anatomical reports, as well as the constancy of the neurovascular pedicle. Three principal branching patterns were observed for the thoracodorsal artery. The thoracodorsal artery divides into three main tributaries in 20/30 (67%), and into two tributaries in 10/30 (33%) of the flaps observed. When three tributaries were observed, one of them was a small recurrent artery for the proximal third of the latissimus dorsi (14/20, 70%). Thus the distal vascularization is actually dependent on three principals in 6/30 (20%) and two principals in 24/30 (80%). From these two or three principals emerge several subsequent longitudinal branches (5 to 9) that have a straight course until their distal anastomoses with segmental arterial pedicles issued from intercostal and lumbar arteries. The latter ligation can thus occur without ischemic damage to the medial and distal aspect of the flap. This study emphasizes that, due to macroscopic anatomic features and systematic intramuscular vascular distribution, the latissimus dorsi is probably the most suitable muscle for the purpose of cardiomyoplasty.

A numerical model describing the coupled evolution of the biogeochemical cycles of carbon, sulfur, calcium, magnesium, phosphorus, and strontium has been developed to describe the long-term changes of atmospheric carbon dioxide and climate during the Phanerozoic. The emphasis is on the effects of coupling the cycles of carbon and strontium. Various interpretations of the observed Phanerozoic history of the seawater Sr-87/Sr-86 ratio are investigated with the model. More specifically, the abilities of continental weathering, volcanism, and surface lithology in generating that signal are tested and compared. It is suggested that the observed fluctuations are mostly due to a changing weatherability over time. It is shown that such a conclusion is very important for the modelling of the carbon cycle. Indeed, it implies that the conventional belief that the evolution of atmospheric carbon dioxide and climate on a long time scale is governed by the balance between the volcanic input of CO2 and the rate of silicate weathering is not true. Rather carbon exchanges between the mantle and the exogenic system are likely to have played a kev role too. Further, the increase of the global weathering rates with increasing surface temperature and/or atmospheric CO2 pressure usually postulated in long-term carbon cycle and climate modelling is also inconsistent with the new model. Other factors appear to have modulated the weatherability of the continents through time, such as mountain building and the existence of glaciers and ice sheets. Based on these observations, a history of atmospheric carbon dioxide and climate during Phanerozoic time, consistent with the strontium isotopic data, is reconstructed with the model and is shown to be compatible with paleoclimatic indicators, such as the timing of glaciation and the estimates of Cretaceous paleotemperatures.

Virulence factors and phenotypes of 61 strains CNF1+ were investigated. Eighty-nine percent of the strains produced an aerobactin and were resistant to the bactericidal activity of sheep serum, both of which are properties of septicemic strains of E coli. None of the strains reacted either with DNA probes corresponding to the enterotoxins STaP, STb, LT-I and LT-IIa, or to the verotoxins VT-I and VT-II. None produced the adhesins K99, Att25 (FY or F17) and Att111. The great majority (93.4%) of the CNF1+E coli possessed both properties. These properties allow CNF1+ to be distinguished from CNF-E coli. [less ▲]

A yield table was compiled for even-aged pure stands of Douglas fir (Pseudotsuga menziesii (MIRBK) FRANCO) in Belgium. It reflects the probable development of normal fully stocked stands under the silviculture at the time of the data collection. The data were collected from 256 temporary sample plots, 87 of which were remeasured 2 or 3 times. A family of functions (the JOHNSON-SCHUMACHER model) was used to develop a site classification system based on the top height at age 50). The standing crop characteristics (number of trees, volume, basal area, mean stem basal area), calculated as a function of age and site index, are derived from stem girth distribution fitted by means of the WEIBULL function. Concerning the increments and the thinnings, the corresponding values were calculated from individual tree girth increments (from borings) and from comparison between stem distributions at the beginning and at the end of a period corresponding to a thinning cycle. The table is the basis on which a set of variable density yield tables will be prepared. The yield of Douglas fir trees in Belgium is also compared with the yield observed in neighbouring European countries. [less ▲]

Among 32 patients with idiopathic central precocious puberty seen during a 3-year period, 1/4 were adopted children from developing countries who showed early sexual maturation during the catch-up process following their arrival in Belgium. To study the possible mechanism accounting for such clinical observations, we used the male rat as a model, and evaluated the effect of variations in early nutritional conditions, by manipulating litter size, on hypothalamic and testicular maturation. We had shown previously that, in the male rat, onset of puberty was preceded, between 15 and 25 days of age, by a transiently increased activation of N-methyl-D-aspartate receptors involved in a facilitatory control of pulsatile secretion of gonadotropin-releasing hormone. We also showed that the proportion of elongated spermatids in testicular cell homogenates increased between 25 and 45 days of age. When compared to pups of a small litter (6/dam), those of a large litter (14/dam) showed a reduced growth rate (1.9 vs. 3.5 g/day) before weaning (21 days), whereas they grew at a similar rate (5.6 vs. 4.7 g/day) after weaning. At 35 days of age, the animals raised in the large litter showed evidence of delayed hypothalamic and testicular maturation when compared to animals from the small litter. Reduction of litter size at 17 days allowed food-restricted pups of a large litter to resume a normal growth rate before weaning.(ABSTRACT TRUNCATED AT 250 WORDS) [less ▲]

Investigations of the effect of epidermal growth factor (EGF) on the expression of four genes involved in the turnover of the extracellular matrix, collagen type I, collagenase, stromelysin and tissue inhibitor of metalloproteinases (TIMP) were performed on four strains of skin fibroblasts in vitro. Addition of EGF to subconfluent cultures for increasing periods of time up to 5 days induced an inhibition of procollagen alpha 1(I) mRNA and a strong stimulation of collagenase (100-fold) and stromelysin (1000-fold) mRNAs, whereas the mRNA of TIMP was increased to a lesser extent (5-fold). After a 40 h pulse with EGF, these effects persisted for 24-48 h after withdrawal of the growth factor and slowly diminished thereafter to attain control values after several days. By culturing fibroblasts for increasing periods of time, different levels of confluence were obtained allowing for the deposition of an extracellular biomatrix. The steady-state level of collagenase and stromelysin mRNAs were profoundly depressed in confluent as against non-confluent cultures, whereas no major change for TIMP and procollagen alpha 1(I) mRNAs was observed. Upon treatment of these cultures with EGF for 48h, the steady-state level of collagenase, stromelysin and TIMP increased, whereas procollagen alpha 1(I) mRNA was slightly reduced. These modifications were, at least in part, dependent upon a regulation of the transcription rate, as suggested from run-off experiments. Similar states of confluence were obtained by seeding cells at increasing densities in short-term cultures in which cell-cell contact predominated. In such culture conditions, the collagenase and stromelysin mRNAs were enhanced in high as compared to low density cultures. The response to EGF was progressively decreased for collagenase, stromelysin and, to a lesser extent, TIMP mRNAs at most densities and a complete lack of response to EGF at the highest cell density was observed. Under all culture conditions the modulation of collagenase mRNA was paralleled by similar modifications of enzyme activity. These results emphasize the importance of the cell-cell contacts and cell-matrix interactions in the expression of the genes coding for metalloproteinases or their inhibitor and their modulation by growth factors.
