A model of the interaction between incident electron precipitation and H2 atmospheres is described. The local degraded primary and secondary electron energy distributions are calculated by using the continuous slowing down approximation. The altitude distribution of the ionization rate and various H and EUV H2 emissions are calculated for four different incident electron spectra. A total EUV H2 emission efficiency of 10.6 kR/incident erg/sq cm per sec is obtained for a pure H2 atmosphere. Comparison with the Voyager Jupiter observations indicates that an incident energy flux of about 8 ergs/sq cm per sec was present at the time of the encounter if the emission is located in an H2-dominated region. The local thermospheric heating rate was about 4 ergs/sq cm per sec for Jupiter and of the order of 0.1 erg/sq cm per sec for Saturn. A globally averaged atomic hydrogen production rate of about 1 x 10 to the 10th atoms/sq cm per sec is induced by the Jovian auroral electron precipitation, largely exceeding the solar EUV dissociation rate.

The dendritic organization of motoneurons was analyzed with the Golgi stain and a morphometric method in the immature and adult human spinal cord. Each motoneuronal column was found to be characterized by a specific orientation of dendritic trees and by a distinct pattern of dendritic bundling. Ventromedial motoneurons have a pyramidal dendritic tree with numerous, short longitudinal branches and elongated dorsal branches. The latter form thick bundles oriented toward the ventral gray commissure. Longitudinal dendrites form a narrow-meshed dendritic plexus, containing abundant microbundles. Motoneurons of the ventromedial column have fewer primary dendrites and a lower ramification index than other motoneurons. Central motoneurons are predominantly oriented longitudinally. The meshes of the rostrocaudal dendritic plexus are looser and the microbundles are finer. Most transverse dendrites run laterally and participate in dendritic bundles which penetrate into the ventrolateral funiculus. The rostrocaudal dendritic domain of ventrolateral motoneurons is the largest dendritic domain of all spinal neurons. The longitudinal dendritic network contains fine microbundles and appears wide-meshed. Transverse dendrites form lateral or medial dendritic bundles depending upon the position of their perikaryon. Dorsolateral motoneurons differ from other motoneurons by their multipolar organization with a slight preponderance of dorsoventral dendritic spread. Rudimentary lateral dendrite bundles are restricted to marginal neurons. The longitudinal plexuses of motoneuronal dendrites and the verticotransverse dendrite bundles of the ventromedial column are well developed in the 26-28-week-old fetus. In contrast, the horizontotransverse dendrite bundles of central and ventrolateral motoneurons can only be recognized from 36 weeks on. The possible specific functions of the various types of dendrites bundles are examined and a laminar dendroarchitectonic schema of the human cord is proposed. [less ▲]

A new approach is presented which allows to describe the binding of different local anesthetics to lipids. Lipids (DL- alpha-dipalmitoylphosphatidylcholine, phosphatidylserine, cardiolipin) are spread at the air-water interface and the anesthetic (procaine, butacaine, tetracaine) injected into the aqueous subphase. The equilibrium constants associated to the interfacial reaction: D+ (subphase) +L- (monolayer) in equilibrium DL (monolayer) (where D+ denotes the anesthetics, L- the lipid anionic site and DL the complex) are calculated from an experimental evaluation of the surface potential of the lipid monolayer. This mode of determination is based essentially on the good correlation between the experimental values of the surface potential and the theoretical predictions from the Gouy-Chapman theory. Fluorescence measurements on liposomes are carried out in order to locate the position of the drug in the lipid layer. This method can be extended to any positively charged drug-anionic lipid interaction. [less ▲]

The clinical relevance of likelihood ratios (L-values) for revising the physician's diagnostic probabilities has been recognized. However, the calculation of L-values, particularly in the case of quantitative or mixed quantitative-binary test results, raises problems that have not yet been addressed. Based on a very general assumption that yields a simple functional form for the likelihood ratio, a method is developed that allows such calculations regardless of the nature and the number of clinical laboratory tests to be interpreted simultaneously. Hence the notion of predictive value (posterior probability) is extended from binary or dichotomized tests to quantitative tests, and from univariate to multivariate clinical laboratory results. The simplicity and flexibility of this approach eliminates difficulties in computation arising from the addition of new data to an existing data base. It is hoped that this method will now allow L-values to be reported along with the original test results in daily laboratory practice. [less ▲]

Purification and properties of the exocellular beta-lactamase of Actinomadura strain R39

The exocellular beta-lactamase (penicillin amido-beta-lactamhydrolase, EC 3.5.2.6) of Actinomadura R39 consists of one single polypeptide chain of molecular weight about 15 200. It exhibits a highly asymmetrical shape, has a low isoelectric point (at pH 5.0) and contains about 9.3% (w/w) of a polydeoxyribonucleotide with which it forms a rather stable complex. Removal of a substantial amount of this deoxyribonucleotide by treatment with DNAase I has no effect on the enzyme activity. The beta-lactamase has a wide spectrum of activity. Penicillins and delta 3-cephalosporins can be either good or poor substrates. Oxacillin, which is a poor substrate of most beta-lactamases from Gram-positive bacteria, is a good substrate of the beta-lactamase of Actinomadura R39. Its best substrate, however, is nitrocefin (kcat/Km: 2300 000 M-1.s-1; catalytic centre activity: 210 s-1). The kcat/Km values observed with some penicillins and delta 3-cephalosporins are similar to the values of the bimolecular rate constants that govern the formation of the acyl-enzyme intermediates between these antibiotics and the serine D-alanyl-D-alanine peptidase that is also secreted by the same strain Actinomadura R39. Such a relationship, however, is not observed with all the beta-lactam compounds tested. [less ▲]

Twenty colonic adenocarcinomas were studied by immunofluorescence with antisera against components of the basement membrane: type IV collagen, laminin and heparan sulfate-rich proteoglycan, as well as antisera against antigens of the connective tissue: type-III collagen, fibronectin and hyaluronectin. Marked alterations of the basement membranes were consistently observed on staining with each one of the first three antisera. In contrast, staining of the normal components of connective tissue was in most cases as intense as in normal colonic mucosa. Hyaluronectin, a marker of peritumoral stroma, was found to be present in 12 out 15 tumors studied. [less ▲]

Mesurer la hauteur d'un arbre avec une précision satisfaisante ne constitue sans doute plus aujourd'hui un problème, eu égard à la qualité des méthodes ou des appareils susceptibles d'être utilisés. Ces appareils, appelés "dendromètres", mettent en oeuvre des principes géométriques (triangles semblables) ou des principes trigonométriques (mesure de pentes). Parmi les premiers, on peut citer la célèbre planchette dendrométrique et le dendromètre de Franck, bien connu de nombreux forestiers belges. Parmi les seconds, on relève les dendromètres Blume-Leiss et Suunto (Dagnelie et al., 1977 ; Rondeux, 1978), conçus pour travailler avec une beaucoup plus grande précision mais malheureusement encore très peu utilisés chez nous. Cette situation est, selon toute vraisemblance, liée à un manque d'informations et à l'absence d'uniformité dans les méthodes de cubage généralement utilisées pour lesquelles nombre de forestiers se contentent d'une estimation rapide ("à l'oeil") de la hauteur, le plus souvent "marchande". L'utilisation de tarifs de cubage s'appuyant sur la connaissance de la grosseur et de la hauteur totale des arbres ou d'un critère de qualité des peuplements telle que la hauteur dominante (Dagnelie et al., 1976, 1977) nécessite cependant une estimation plus rigoureuse des hauteurs, étant donné que ces dernières concernent souvent un nombre limité d'arbres. Dans cette perspective, à défaut de disposer de dendromètres sophistiqués et relativement coûteux, l'utilisation d'un clinomètre nous paraît recommandable. Cet appareil, destiné à mesurer des angles (pentes) réalise, en effet, à de nombreux égards, un compromis intéressant en matière de coût, de commodité d'utilisation et de précision. Il peut en outre s'avérer plus efficace que les dendromètres actuels ou les suppléer pour résoudre divers problèmes de mesure inhérents aux conditions parfois difficiles de travail en forêt.

Spectral variations detected within the last three decades for He II 4686 A, forbidden lines O III and other high excitation lines in the low-excitation planetary nebula HD 138403, are shown to suggest appreciable activity in the deep atmospheric layers of the nucleus, and an increase of the excitation of the nebula. The spectrum of the nebula is found to be unusual due to the presence of red and blue emission satellites around the central Balmer (H-beta - H9) lines and forbidden lines O II 3726, 3729 A, with a velocity separation equal to plus 122 and minus 126 km/s, respectively. These features are interpreted as evidence for mass outflow from the central object via the selective radiation process of edge and/or line locking mechanisms. [less ▲]

In 9 obese patients, epinephrine infusion (10 microgram/min) did not significantly modify the mean arterial blood pressure (MBP) in basal conditions. This infusion reduced MBP (-7 mm Hg, p less than 0.05) after 13 days of protein-supplemented fasting. This difference in the cardio-vascular reactivity to circulatory epinephrine could contribute to the decrease in the arterial blood pressure observed during protein-supplemented fasting. [less ▲]

A patient developed concomitantly chondritis of the two auricles, diffuse cutaneous vasculitis and actinic granulomas. Alterations in skin and cartilage were prominent in the elastic tissue. Anticollagen type II antibodies were absent from the serum and there was no deposit of immunoreactants in cartilages. In this form of relapsing polychondritis, the pathomechanism resembles that of diffuse actinic arteritis as proposed by O'Brien. It is concluded that relapsing polychondritis may represent a heterogeneous syndrome with regard to its pathogenesis. [less ▲]

The adhesion of normal rat peritoneal macrophages to normal rat glomerular epithelial or mesangial cells has been studied in vitro after a 60 min incubation at 37 degree C. After washing, the cell preparations were examined by phase contrast or scanning electron microscopy. Quantitative studies were also performed using macrophages labelled with 99mTc tin colloids. Peritoneal macrophages predominantly adhered to the cultured mesangial cells. The percent-age of labelled macrophages adhering to these cells was about 10 times higher than that of labelled macrophages adhering to the cultured epithelial cells. This percentage increased proportionally to the number of labelled macrophages added, and was strongly reduced by the prior incubation of macrophagic cells with aggregated IgG, with anti-fibronectin IgG, or with F(ab')2 fragments of anti-fibronectin IgG. Furthermore, the macrophage-mesangial cell interaction was significantly reduced by the prior incubation of mesangial cells with anti-fibronectin IgG or with F(ab')2 fragments of anti-fibronectin IgG. The data demonstrate that normal rat peritoneal macrophages preferentially adhere in vitro to normal rat glomerular mesangial cells, and that this binding may be modulated, at least, by: (a) the Fc receptor binding activity of macrophages; (b) the fibronectin molecules available at the surface of macrophages and of mesangial cells.

Parameters of cortisol metabolism were studied in pregnancy and early post partum and in non pregnant women. Total serum cortisol was measured by a specific radioimmunoassay and its unbound- and CBG-bound fractions by equilibrium dialysis at 37 degrees C. CBG was measured directly, by an immunodiffusion method (true CBG) and indirectly, by the Scatchard analysis of its interaction with labelled cortisol (PT). During pregnancy the increases in true CBG and total cortisol concentrations were grossly parallel but the PT/true CBG ratio fell from almost 1 in non-pregnant and delivered women to 0.6 during the second half of pregnancy. At 6 p.m., unbound cortisol was significantly higher in outpatients during the 2d half of pregnancy than in non pregnant controls (0.017 vs 0.009 10(-6) mol/l). In hospitalized resting patients, unbound cortisol concentrations were the same in pregnant and non pregnant women except for a significantly higher level of unbound cortisol at midnight during the second half of pregnancy. Circadian variations of cortisol secretion persisted throughout pregnancy. It is concluded that in pregnancy (1) hypothalamic control of maternal adrenal secretion still prevails, (2) the increase in total cortisol is essentially due to that of CBG, (3) the unbound cortisol is normal or, at times, slightly increased and (4) variations in the PT/true CBG ratios may be explained by the presence of steroids (progesterone and 17-OH-progesterone) with a high affinity for CBG. The physiological significance of the mild hypercortisolism of pregnancy is discussed. [less ▲]

We have found that sera from humans with Chagas' disease and Rhesus monkeys infected with Trypanosoma cruzi contain IgM and IgG antibodies, which react with structures in a variety of connective tissues. These antibodies react with laminin but not with various other purified connective tissue components like collagen types I, III, IV, and V, fibronectin, heparan sulfate (BM-1) proteoglycan, or chondronectin. The tissue-reacting antibodies were isolated by absorption to a laminin-Sepharose column. The bound fraction contained all the tissue-reacting antibodies. These antibodies strongly stained trypomastigotes and amastigotes, but weakly stained epimastigotes. These studies show that sera from T. cruzi-infected primates contain antilaminin antibodies, which may be produced by those host in response to a laminin-like molecule present in the parasite.

Recently, we suggested that the cell coat of the surface epithelial cells of the palatal shelves and especially its sialyl groups are implied in the adhesion process which initiates the constitution of the secondary palate. In this work, use of cationized ferritin which interacts with anionic receptors of the plasma membrane give us the possibility to render these sialic acids visible. After five minutes incubation in presence of cationized ferritin, the labeling particles are distributed in monolayer over the plasmalemma of epithelial cells. Subsequent incubation in cationized ferritin free medium results in clustering of the marker followed by the detachment of the labeled patches. Otherwise, incubation in the presence of neuraminidase from Clostridium perfringens before the polycationic ligand contact prevents labeling. We think that lateral migration modifications of the anionic receptor could be associated with changes of the shelves capacity to adhere. [less ▲]

Serial measurements of serum uric acid were performed on patients suffering from acute myocardial infarction. Nearly 80 percent of the cases demonstrated a fall in uric acid concentrations during the first two days of hospitalization and a subsequent return to initial levels within six to eight days. There was a relationship between the decrease in uric acid levels and the serum lactate dehydrogenase activity. No evidence could be found that male patients were hyperuricemic as compared to control subjects. However, female patients between 40 and 60 years of age demonstrated significantly higher uric acid levels than healthy women of corresponding ages, even after adjustment for diuretic use. [less ▲]

The aim of this experiment was to study the origin and formation of microporosities in a Ni-5% Ti-0.2% C alloy which has been solidified and quenched, and to compare it to the previously developed mathematical model. In the selected alloy, the porosity may result from gases formed during solidification (for example by chemical reaction). The results show that solidification conditions influence microporosity formation through the fraction eutectic and this suggests that it is possible to relate susceptibility to microporosity formation to the fraction eutectic. The results also confirm that for solid solution alloys such as Ni-5% Ti0.2% C, the fraction eutectic increases when the ratio G/R decreases. [less ▲]
