It is shown that for a photon energy of 16.85 eV the translational energy surprisal of the C2H3++F dissociation products from C2H3F+ has a bimodal behaviour. The possibility of considering the bimodal surprisal as due to the superposition of two translational energy distributions is consistent with the theoretical assumption of the concurrence of two channels in this dissociation process. The characteristics of these distributions, i.e. the energy width and the relative abundance, are in agreement with the results of an ab initio quantum-mechanical calculation of the dynamics of this dissociation. They are consistent with the simultaneous occurrence of a statistical dissociation of C2H3F+(X2A') into C2H3+(X1A') and an isolated state dissociation of C2H3F+(C2A") into C2H3+(a3A"). Negative lambda values obtained for the surprisal of both these distributions indicate an inversion of the translational level population of the dissociation products. [less ▲]

The effectiveness of non pharmacological treatment of chronic arterial hypertension has been evaluated in 116 treated or not primary hypertensive out-patients. Those receiving diuretics were however excluded. This population was requested to follow for 3 months a modification of their usual diet characterized by salt restriction combined with energy intake restriction when the patients were above their ideal body weight. Only 62 patients (53%) completed the study. However, this approach was effective by decreasing blood pressure and total cholesterol. The weight loss appears the most effective way to decrease blood pressure in untreated patients, but needs 3 months to be significant. In drug-treated patients, the sodium restriction significantly influences the blood pressure level, already after 1 month. However, salt sensitivity has been noted, especially in the most severe forms of the hypertensive disease. The combination of both modifications (weight loss and sodium restriction) does not appear to be more effective than each separate dietary measure. [less ▲]

A series of sulphonylthioureas related to torasemide, a high ceiling loop diuretic, were synthesized and found to inhibit the Na+ 2Cl- K+ co-transporter of the thick ascending limb of the loop of Henlé. Their diuretic properties were studied (30 mg kg-1) after oral administration to rats. Lipophilic derivatives very active in-vitro, were found inactive orally and intraperitoneally in rats. The four most active compounds were examined for their dose-dependent diuresis. Three of them showed a potency, water and electrolyte excretion similar to torasemide. The fourth molecule, a sulphonylthiourea (BM 20), exhibited relative potassium-sparing properties and a minimal diuretic dose of 0.001 mg kg-1, 200 times lower than torasemide. [less ▲]

The recombinant plasmid pAL-A3 bears a (poly ManA) alginate lyase-encoding gene that originates from the marine bacterium ATCC 433367 (Brown et al., Appl. Environ. Microbiol. (1991) 57, 1870-1872). The alginate lyase produced by Escherichia coli TC4 harbouring pAL-A3 was purified to protein homogeneity and the corresponding gene sequenced, giving access to the first known primary structure of an alginate lyase. The 265-amino acid residue alginate lyase showed lytic activity on a Pseudomonas aeruginosa alginate isolated from a cystic fibrosis patient. Unexpectedly, the alginate lyase thus characterized differed from that isolated from the culture medium of the bacterium ATCC 433367 (Romeo and Preston, Biochemistry (1986) 25, 8385-8391). [less ▲]

In order to simulate the cavity growth of an underground gasifier in thin seams, at great depth, Wilks1,2 has developed an original model based on the distribution of fluid flows around an injection well. In this paper, we aim to introduce within this model a description of chemical processes on the wall and within the fluid phase, in order to determine the temperature and concentration profiles along the coal wall. These profiles are dependent only on two factors: the transfer coefficients and the energy balance of the gas generator. A study of the sensitivity of the operating variables has been carried out.

Given the present state of our knowledge, the question about the links between Egyptian and Greek medicine is far from being resolved. Some convergences can in fact be detected, but when you study them further, you will find that they reveal a loan, or a simple coincidence, or else a false interpretation of the sources. At the end of the sixth century BC, Pharaonic medicine was outclassed and influenced little by little by Greek medicine. Lastly, the Coptic medical treatises, composed in Egyptian language, but written in Greek characters, combine some Greek and finally Arabic borrowings. [less ▲]

Changes in pulmonary endothelial permeability and in microvascular hemodynamics in response to capsaicin (10(-4) M) were investigated in isolated, perfused rabbit lungs. Blood-free perfusate was recirculated through ventilated lungs in an isogravimetric state, under zone III conditions with a constant flow. Using the occlusions method, the total pressure gradient between the arterial and the venous levels (delta Pt) was partitioned into four components: arterial (delta Pa), pre-(delta Pa') and post-(delta Pv') capillary, and venous (delta Pv). The capillary filtration coefficient (Kf,c) was evaluated by measuring the amount of fluid filtering through the endothelium when arterial and venous pressures were suddenly increased. Capsaicin caused no changes in the vascular pressures at any level of the pulmonary circulation but induced a significant 3-fold increase in the Kf,c (P < 0.05). This reaction was accompanied by pulmonary oedema. The mechanisms involved in the permeability changes were investigated by testing the capacity of different drugs to block the response to capsaicin. Clonidine (10(-7) M to 10(-5) M), morphine (10(-6) M), aspirin (10(-3) M), ketanserin (10(-8) M) and (+/)- CP 96,345 (10(-6) M), an antagonist of neurokinin NK1 receptor, completely prevented the effects of capsaicin on the Kf,c. In contrast, terfenadine (10(-7)) together with cimetidine (10(-5) M) had no protective effect against capsaicin. It was concluded that capsaicin-induced pulmonary oedema was due to an increase in the capillary filtration coefficient and not to hemodynamic changes. This alteration in the endothelium permeability is mediated by the release of endogenous peptides from C-fibers upon the action of capsaicin and subsequent activation of NK1 receptors, probably by substance P. Moreover, 5-hydroxytryptamine receptors and arachidonic acid derivates are also involved in this reaction [less ▲]

A recently described personal method based on image analysis of histological sections was used in order to quantify lung colony formation by B16 melanoma cells injected intravenously into the mouse. These tumor cells were preincubated in vitro either with fibronectin (FN), laminin (LN) or fibroblasts (FB), which are implicated in the process of invasion and metastasis. Thanks to this method, a more accurate analysis of lung colonies (section area and number) formed by tumor cells was realized. By image analysis, we show that when FB were mixed with B16 cells, a drastic increase of tumor sections number and area was induced. LN increased the tumor sections area, but not their number. No effect of FN on B16 cells was observed. LN and FN promoted tumor anchorage in the depth of the lungs while FB reduced the latter. These facts could explain the contradictory results obtained by simply counting macroscopically superficial lung colonies. When cultured in vitro, these B16 melanoma cells did not produce any type of IV collagenase, either alone or in the presence of LN or FN, but in cocultures (B16 with 3T3) and in fibroblasts cultures, this enzyme was present. This could explain, among other factors, why the rate of invasiveness exerted by B16 cells is higher when the latter are coinjected with FB. [less ▲]

Growth hormone (GH) gene expression in mammals is regulated by the interaction of the transcription factor Pit-1 with two binding sites within the proximal promoter. Four sequences, homologous to the mammalian Pit-1 motif occur in the rainbow trout (Oncorhynchus mykiss) GHII (rtGH) gene promoter, two of which partly overlap. The three regions containing these putative Pit-1 binding sequences were protected from deoxyribonuclease I digestion by nuclear extracts of GC cells, a rat pituitary tumor cell line producing Pit-1. In gel shift assays, nuclear proteins from GC cells and from trout pituitaries were found to interact specifically with one of these protected sites. Transfection experiments showed that the rtGH promoter is transcnptionally active in GC cells, the response being strongly enhanced in the presence of a cAMP analogue. The results demonstrate that rat Pit-1 binds to and activates the rtGH promoter, indicating that the basic mechanisms regulating GH gene transcription have been conserved between fish and mammals.

Iron transport in plasma is carried out by transferrin, which donates iron to cells through its interaction with a specific membrane receptor. The soluble form of the transferrin receptor has been identified in plasma. Dosage of the soluble receptor represents a simple, reliable, quantitative assay of erythropoiesis, which should replace the standard ferrokinetic measurement. Using this dosage, it is now possible to investigate the pathophysiology of anemia in many conditions, and to analyze the erythropoietic response to treatment with recombinant erythropoietin.

We carried out a pilot study on the use of recombinant human erythropoietin (rHuEPO) to accelerate erythropoietic engraftment in paediatric patients undergoing allogeneic BMT. rHuEPO was administered intravenously at a dose of 75 U/kg per day for 30 d after transplant. Erythroid repopulation, evaluated sequentially through the serum transferrin receptor, was faster in 15 patients receiving rHuEPO than in 16 historical controls (P = 0.0003). This faster erythroid engraftment resulted in a reduction in the total number of red blood cell units required to reach transfusion independence (2.7 +/- 1.2 v 4.2 +/- 2.3, P = 0.027). No significant difference in leucocyte or platelet regeneration was observed. These findings indicate that rHuEPO administration can accelerate erythroid recovery after allogeneic BMT and reduce red cell transfusion requirements with no stem-cell competition effect. [less ▲]

The best crystals have been grown at 15 degrees C, from solutions containing 8% polyethylene glycol 10,000 at pH values ranging from 3.9 to 6.0. These crystals diffract to a resolution of 3.5 A and have a space group P6(1)22 (or enantiomorph) with unit cell dimensions of a = b = 162.2 A, c = 171.8 A, alpha = beta = 90 degrees, gamma = 120 degrees. The molecular mass and cell dimensions suggest that there is one molecule of enzyme per asymmetric unit.

The hGH/hCS genes, clustered on chromosome 17 in the 5' to 3' order GH-N, CS-L, CS-A, GH-V and CS-B, show a high degree of sequence identity. The expression product of the GH-V gene is the placental growth hormone, which replaces pituitary GH in maternal blood throughout pregnancy. By means of mRNA competitive hybridization using P-32-labelled and unlabelled 30 bases long oligonucleotides, we first optimized specific hybridization conditions. In situ hybridization was then performed to locate the GH-V mRNA encoding placental growth hormone. The hGH-V gene appears expressed in the placental syncytiotrophoblast. Unlike the CS-A and CS-B genes (both encoding hPL) which are expressed uniformly in the syncytiotrophoblast, the GH-V mRNA is located in a few syncytiotrophoblast cells only. [less ▲]

The flash patterns of oxygen evolution after pre-illumination by continuous light or by a flash sequence were compared in etiochloroplasts and mature chloroplasts of barley. In both types of plastids sub-saturating continuous illumination of some seconds strongly affected the S3 but not the S2 state of the oxygen-evolving complex. This result is ascribed to efficient charge recombination of S3 with the acceptor side of photosystem II, favoured by partial reduction of the plastoquinone pool. The increase of S3 observed in the presence of dichlorophenolindophenol in etiochloroplasts confirms this interpretation. These observations strengthen the recent hypothesis of a conformational change during the transition from S2 to S3 recently proposed to interpret the different susceptibility of these two states to hydroxylamine and hydrazine (F. Frank and G. H. Schmid, Biochim. Biophys. Acta 977, 215-218 (1989); J. Messinger, U. Wacker, and G. Renger, Biochemistry 30,7852-7862 (1991)). [less ▲]

A series of antisense oligonucleotides were developed to inhibit specifically expression of a mutated exogenous gene for collagen without inhibiting expression of an endogenous gene for the same protein. The test system consisted of mouse NIH 3T3 cells that were stably transfected with an internally deleted construct of the human gene for the pro alpha 1(I) chain of type I procollagen [Olsen et al. (1991) J. Biol. Chem. 266, 1117]. The target site was a region at the 3' end of exon 1 and the first few nucleotides of intron 1 of the exogenous human gene that differed in sequence by nine nucleotides from the sequence of the endogenous mouse gene. Expression of the two genes was assayed by Western blot with cross-reacting antibodies and by steady-state levels of mRNAs. None of the oligonucleotides were effective in concentrations up to 25 microM when administered without any carrier. However, when administered with 5 or 10 micrograms/mL lipofectin, one of the oligonucleotides in concentrations of 0.1-0.2 microM inhibited expression of the exogenous gene from 50% to 80% without significant inhibition of expression of the endogenous gene. Also, a missense version of the same oligonucleotide had no significant effect, and the inhibition observed with the most effective oligonucleotide was abolished by a single base change. Time course experiments indicated that, after a 4-h treatment, inhibition appeared at 8 h and persisted for at least 22 h.(ABSTRACT TRUNCATED AT 250 WORDS) [less ▲]

Using two different methods, we compute the fractal dimension of the power spectrum associated with numerical solutions of the spatially homogeneous Bianchi IX cosmological model in Misner-Chitre coordinates. According to Perdang's criterion, the noninteger character of this dimension is reflection of chaos and can be used to measure it, in the same spirit as the Lyapunov exponent of the Kolmogorov entropy. The results obtained indicate the chaotic nature of the behaviour of the Bianchi IX model near the cosmological singularity. [less ▲]

Sequential sampling of precipitation under mature spruce trees and time-series analysis of the data were performed in order to assess, in natural conditions, the relative importance of different factors that could influence the leaching and uptake of inorganic ions in the canopy. Eleven rain events were analyzed in order to estimate how external factors, rain intensity, H+, and ionic concentration of the incident rain influence the ionic throughfall concentrations and the net throughfall fluxes. The results led to the conclusion that leaching or uptake mostly occur by diffusion. The influence of the open rain acidity was not conclusive; however, it was shown that the tested external factors only controlled a few percent of the variation of the data. By contrast, the autocorrelation of the data always explained a large portion of the variance. lt could result from the gradual changes in the course time of internal factors related to the exchange system including waxes, cuticles, apoplast and xylem sap. These constituents were known to control the exchange at the canopy surface and to be sensitive to the plant physiology and environmental conditions. [less ▲]

The catalytic properties of three class B beta-lactamases (from Pseudomonas maltophilia, Aeromonas hydrophila and Bacillus cereus) were studied and compared with those of the Bacteroides fragilis enzyme. The A. hydrophila beta-lactamase exhibited a unique specificity profile and could be considered as a rather specific 'carbapenemase'. No relationships were found between sequence similarities and catalytic properties. The problem of the repartition of class B beta-lactamases into sub-classes is discussed. Improved purification methods were devised for the P. maltophilia and A. hydrophila beta-lactamases including, for the latter enzyme, a very efficient affinity chromatography step on a Zn(2+)-chelate column.

To assess the respiratory response to abdominal and rib cage muscle paralysis, we measured tidal volume, esophageal and gastric pressures, arterial blood gases, and the electromyogram (EMG) of the diaphragm during progressive epidural anesthesia (lidocaine 2%) in 35 supine anesthetized dogs. The EMG activity of the diaphragm was measured with fine-wire electrodes; the abdominal cavity was thus left intact. Paralysis of the abdominal muscles alone did not produce any alterations. In contrast, when all rib cage muscles were also paralyzed, there were substantial increases in the peak height and the rate of rise of diaphragmatic EMG activity that were associated with a decrease in tidal volume and an increase in arterial PCO2 (PaCO2); swings in transdiaphragmatic pressure, however, were unchanged. The increased diaphragmatic activation due to rib cage muscle paralysis persisted after bilateral cervical vagotomy and was well explained by the increased PaCO2. These observations indicate that in the dog 1) the rib cage muscles contribute significantly to tidal volume, and their paralysis causes, through the increased hypercapnic drive, a compensatory increase in diaphragmatic activation; and 2) the rib cage inspiratory muscles enhance the diaphragm's ability to generate pressure during breathing.

The electrostatic potentials (EPS) corrected for polarization (TPS) of the aromatic compounds benzene, aniline, chlorobenzene, nitrobenzene, phenol, benzamide, and N-phenylacetamide have been calculated at the ab initio SCF level within three basis sets: 6-31G**, MINI-1, and STO-3G. For chlorobenzene in its MINI-1-optimized geometry, the calculation was also performed within MINI-1**. By reference to 6-31G**, the MINI-1-computed EP is much more satisfactory than the STO-3G-computed EP, whereas the MINI-I and STO-3G basis sets give very similar total potentials corrected for polarization (TPs). The MINI-1** basis set appears to be miscalibrated for computing EPs. It provides qualitative results that differ from those obtained with the 6-31G** basis set. The EP has a negative well above the middle of the benzene ring, while the TP exhibits a negative crown just above the benzene carbon atoms, where electrophilic attack takes place. The TP calculated for the interaction of nitrobenzene with a hydride ion instead of a proton allowed analyzation of the effects of polarization on the positive EP above the N-C bond. [less ▲]

The paper is about the dominance and coalition relationship among male chimpanzees. It focuses on the dependance relationship between the members of the coalition and distinguishes stable and unstable coalitions. A coalition is unstable if the support of the dominated individual is conditional and stable if it is not (i.e. among two brothers). In an unstable coalition the dominated indivuual can afford some priviledge, the dominant is very dependent on the subordinate and the relationship with the dominant is tense. Analogies with human power relationships are suggested. [less ▲]

Interactions between cancer cells and laminin, a major component of basement membranes, play a critical role at several steps of the complex process of tumor invasion and metastasis. These interactions are mediated through a large variety of cell surface proteins designated as laminin receptors and/or laminin-binding proteins. The growing number of identified laminin binding proteins and domains of this glycoprotein that are biologically active illustrate the complexity of cellular interactions with laminin. The 67-kD laminin receptor (67 LR) was the first protein identified in 1983 as a high-affinity laminin receptor, and its expression is dramatically increased in a large variety of cancer cells. The 67 LR is the subject of several controversies and confusion generated mainly by two events. First, the identification of several new laminin-binding proteins has raised the difficult task of attributing specific functions to specific receptors in contrast to initial beliefs that all cellular laminin-driven biological activities were mediated through the 67 LR. The second source of controversy is the large molecular-weight discrepancy between the 37-kD polypeptide encoded by the 67 LR cDNA clone and the mature 67 LR. In this manuscript, a critical and extensive review of the data accumulated on the 67 LR is presented regarding both its molecular structure and its role during tumor invasion and metastasis. A hypothetical model of the 67 LR is also proposed. Since the first identification of the 67 LR, at least 14 other cell surface molecules have been reported to be potential laminin receptors or laminin-binding proteins. These include members of the beta-galactoside-binding lectin family, seven members of the integrin family, the galactosyltransferase and some not yet fully characterized cell surface molecules. These laminin receptors and laminin-binding proteins are also described and their functions are also discussed with a particular emphasis on their participation in the constitution of the invasive phenotype.

The erythrocyte Na-Li countertransport (CT) has been considered as a marker of genetic propension to essential hypertension, but also to be linked to atherosclerosis risk factors. We have evaluated these relationships by measuring the Na-Li CT, blood pressure levels, the family predisposition to hypertension, body mass index, subscapular skin-fold thickness, waist/hip ratio, and plasma lipids in 43 young adults (22 to 23 years; 13 with a positive family history of hypertension), followed since adolescence (+/- 10 years) to analyze the natural history of blood pressure in this period of life. The Na-Li CT was negatively correlated with the HDL cholesterol (r = -0.37) and the HDL cholesterol/total cholesterol ratio (r = -0.44). This transport system was positively correlated to family history of hypertension (r = 0.38), waist/hip ratio, and the diastolic blood pressure. When the family history of hypertension was present, Na-Li CT and diastolic blood pressure were higher (P < .05), but the HDL cholesterol was lower (P < .01). After separating people according to the blood pressure level during adolescence in two groups, one lower than the 75th percentile (P75), and one higher, we notice that the latter remains characterized by a higher systolic blood pressure. But neither the Na-Li CT nor family history of hypertension and plasma lipids could explain the difference in the blood pressure behavior during this period. Thus, an increase of RBC Na-Li CT activity in young adults would suggest a higher cardiovascular risk rather than to be a simple marker of a hypertensive risk. [less ▲]

Since the mid-eighties, a sand pit located at the boundary of Mellery, a small village in Belgium, has been used as a dumping ground for industrial waste. After a particularly dry summer, many people complained of very foul smells coming from the dumping ground. An analysis of the environmental atmosphere detected alkanes and chlorinated saturated and unsaturated hydrocarbons in various concentrations. Consequently, the Belgian Ministry of the Environment requested additional measurements from the dumping site and the surrounding regions. Given the hazards and possible ill health effects associated with simultaneous exposure to low levels of many chemicals, biomarkers of personal exposure were measured in a representative group of people living in this village. The cytogenetic consequences of daily exposure to a mixture of genotoxicants were measured by the Sister Chromatid Exchange assay. The study included a group of 51 environmentally exposed persons (including 11 children) and 52 controls. A significant increase in Sister Chromatid Exchange frequency was detected among the inhabitants of the village compared to that of the control group, especially among the children living in Mellery as compared to the matched control children.

Two-d-old leaves which do not contain prolamellar bodies synthesize active protochlorophyllide in darkness. When protochlorophyllide is photoreduced by one intense white flash, a main chlorophyllide species emitting at 690 nm is formed. After the photoreduction, the emission maximum is shifted to 675 nm within 5 s. This result suggests that in young leaves, chlorophyllide formed after one flash is quickly released from the active site of NADPH: protochlorophyllide oxidoreductase. This interpretation is strenghtened by time-resolved fluorescence measurements at room temperature, showing that 675 nm emitting chlorophyllide does not transfer excitation energy to the 696 nm emitting chlorophyllide which is formed in very low amount. In 10-d-old bean leaves, the 690 nm chlorophyllide emitting species formed after one short flash undergoes the well-known rapid and Shibata spectral shifts. The 675 nm emitting chlorophyllide appears only as a shoulder. At both ages, the fluorescence intensity of the active protochlorophyllide strongly decreases during and after photoreduction, suggesting rapid modifications in the close environment of the pigment.

The development of a Geographic Information System (G.I.S.) leads to new prospects in the field of broad-scale forest inventory, the main objective being to estimate areas and growing stock for the different stand types in a given region. The dot grid method typically used to estimate the areas in the case of systematic sampling, can be advantageously replaced by the creation within a G.I.S., of a stand map, that can be overlaid with data issued from the inventory. A methodology is proposed, to produce such a map using color infrared aerial photos at a scale of 1:25,000. Geographical data are processed using ILWIS software. The method has been tested on a 200 km² forest area. The error rate for interpretation of stand types is less than 6 % if one considers the confusions between species. The crossing of this stand map with the sample plots layer provides an estimation of the growing stock per stand type. [less ▲]

Synthesis of Bi2-xPbxSr2Ca2Cu3O10-y (x = 0 and x = 0.3) has been performed using the glass recrystallization route technique. After splat quenching, the samples were annealed at 820, 850 or 870-degrees-C for 96 or 144 h (with one intermediary grinding). High-resolution polarization micrographs and electrical (and magnetic susceptibility) measurements have been taken. Various growth mechanisms can thus be checked, and the physical properties are studied in relation to the microstructure. It is found that the 2223 phase does not crystallize directly from the amorphous one but results from a dissolution-reprecipitation process. The stability of the 2212 phase is emphasized. The 2201 phase precipitates at high temperature and rapidly reacts with the melt to form the 2223 phase. The kinetics of the lead-substituted sample seems to be controlled by the Ca2PbO4 phase. which acts as a flux. [less ▲]

The 92-kD type IV collagenase is a member of the metalloproteinase family which degrades type IV collagen, a major component of basement membrane and is involved in tumor invasion and metastasis. The promoter and adjacent regulatory sequences of the 92-kD type IV collagenase have been identified previously and three cis-acting elements homologous to the binding sites for AP-1, NF-KB and SP-1 proteins contributed to induction of the promoter activity by 12-O-tetradecanoylphorbol 13-acetate (TPA) and tumor necrosis factor (TNF-alpha) in HT1080 cells. To date, no direct correlation between promoter activity and expression of the 92-kD type IV collagenase has been reported in normal or cancer cells. In this study, the effects of the transcriptional stimulation of the 92-kD type IV collagenase gene on the expression of the enzyme in human A2058 melanoma cells was analyzed by zymography experiments. Quantitative immunoblots using a monoclonal antibody that recognized specifically and exclusively the 92-kD type IV collagenase, confirmed that the 92-kD gelatinase was 92-kD type IV collagenase. Stimulation of the promoter activity resulted in increased gelatinase activity in the culture medium of A2058 cells. A direct correlation between TPA- and TNF-alpha-mediated promoter stimulation of the 92-kD type IV collagenase gene and its expression was also demonstrated in the human fibrosarcoma HT1080 cells. Interleukin-1 alpha failed to induce 92-kD gene promoter activity and type IV collagenase expression in melanoma and fibrosarcoma cell lines. Our data demonstrated that TPA- and TNF-alpha-induced 92-kD type IV collagenase promoter stimulation leads to a proportional increase of enzyme expression and secretion and thus could contribute to the activation of the invasive phenotype.
