Allelic variation in the structural or regulatory sequences of growth hormone and its receptor genes might directly or indirectly affect milk traits. This possibility prompted us to investigate the eventual relationships of restriction fragment length polymorphisms at the locus of bovine growth hormone (using TagI and MspI restriction enzymes) and its receptor (using TaqI restriction enzyme) production traits of bulls. Holstein-Friesian bulls were used in this experiment, and data were analyzed with a fixed linear model. The restriction fragment length polymorphisms at the growth hormone locus did not affect the milk traits studied. Six restriction enzyme TaqI bands of 7.1, 6.2, 5.7, 5.4, 4.2, and 3.3 kb with nine patterns were observed after hybridization by a cDNA probe containing the coding sequences for the intracellular C-terminal part of the receptor. The effect of this polymorphism on PTA for milk protein percentage was highly significant and was favorable for the rare (6.6%) 5.7- and 5.4-kb pattern. Our results indicate that further study is needed to explain the DNA polymorphism and to obtain more definite conclusions about effects on milk traits. [less ▲]

he chiral phase transition of a hot and dense system of quarks is studied within a modified SU(3) NJL Lagrangian that implements the QCD scale anomaly. The u- and s-quark condensates can or can not feel the same chiral restoration depending on the considered region of the three-dimensional space (Tc, muuc, musc). The temperature behaviour of the pressure and the energy and entropy densities of the u- and s-quark system is investigated. At high temperature, the non-vanishing bare s-quark mass only modifies slightly the usual behaviour associated with an ideal quark gas. [less ▲]

Weight reduction is essential in the management of most non-insulin-dependent diabetics, but this therapeutical goal is difficult to obtain. In this double-blind parallel study, 82 non-insulin-dependent diabetics, moderately obese (BMI = 30 - 39 kg/m2), were given for an 8-week period either placebo (P) or fluoxetine (F), a specific serotonin reuptake inhibitor, in addition to their usual antidiabetic treatment. Thirty-nine of them received 60 mg fluoxetine a day and 43 were given the placebo. At admission, both groups had similar weight excess, metabolic control and serum lipid values. In comparison with the P-treated subjects, those treated with fluoxetine (F) lost more weight after 3 weeks (-1.9 vs. -0.7 kg, p < -0.0009) and after 8 weeks (-3.1 vs. -0.9 kg, p < 0.0007). Fasting blood glucose decreased in group F after 3 weeks (-1.5 vs -0.4 mmol/L, p < 0.003) and after 8 weeks (-1.7 vs. -0.02 mmol/L, p < 0.0004). HbAlc decreased from 8.5% to 7.7% in group F and from 8.6% to 8.3% in group P (p = 0.057). Mean triglyceride level was also reduced in group F after 8 weeks (p = 0.042). Fasting C-peptide did not change in either group, but fasting insulin values decreased in group F after 3 weeks (p < 0.02) and after 8 weeks (p < 0.05). The insulin/C-peptide molar ratio decreased significantly in group F after 3 weeks (p < 0.04) and after 8 weeks (p < 0.05) in comparison with group P. The drug was generally well tolerated and no major side effects were reported. In conclusion, the addition of fluoxetine to the usual oral hypoglycemic agent therapy might be beneficial in obese non-insulin-dependent diabetics, at least on a short-term basis. [less ▲]

The reduction of high concentrations of gypsum (up to 110 kg/m(3)) is investigated in a two stage immobilised cell bioreactor. The first stage is mainly colonised by a consortium of acidogenic bacteria and sulphate reducing bacteria oxidising volatile fatty acids with more than 2 carbons (mainly, butyrate and propionate). The gypsum consumption rate is rather high (ii kg/m(3).day). Most of acetate remains unconverted in this first stage. It is partially converted in the second stage (residence time : 12 days) which is predominantly colonised by acetate oxidising bacteria The gypsum consumption rate is much lower than in the first stage : 3 kg/m(3).day. With both stages, it is possible to reach an almost complete conversion of gypsum with an overall capacity of 6.1 kg gypsum/m(3).day. We propose also a very simple model to describe the different transformation rates. It allows us to clearly identify the activity levels of the different types of sulphate reducing bacteria in both stages. Copyright (C) 1996 IAWQ. [less ▲]

The precise localization of DNA and RNA within rat hepatocyte nucleoli during the process of D-galactosamine-induced nucleolar segregation has been studied by using sensitive methods for their detection: osmium-ammine staining and terminal deoxynucleotidyl transferase reaction for DNA, and immunoelectron microscopy with anti-RNA antibodies, RNase-gold, and autoradiography with tritiated orotic acid for RNA. The blocking of transcription was followed by the disappearance of intranucleolar condensed chromatin. Agglomerates of thin extended DNA filaments were found to change their location to the nucleolar periphery and to coalesce with each other. At the last stage of nucleolar segregation they were concentrated at the pole of the nucleolar fibrillar remnant while the rest of the nucleolus did not contain any DNA. No DNA was found in the dense fibrillar component of both intact and treated hepatocyte nucleoli. During the process of nucleolar segregation the bulk of the nucleolar RNA was found within the so-called spherical bodies. This RNA appeared to be synthesized shortly before or even after drug administration. The results obtained are in agreement with the hypothesis that the fibrillar centers are the site of nucleolar transcription. They also show that uncompleted molecules of pre-rRNA whose synthesis has been blocked are segregated from the rest of nucleolar RNA species into the spherical bodies. [less ▲]

The mivazerol and three of its methylated derivatives are studied at the ab initio SCF level within the MINI-1 and 6-31G basis sets. This study aimed at determining some probable conformations, either neutral or protonated, that could interact with the alpha 2 adrenoceptors. The solvent effect was also studied within the Onsager's solvent model at the two dielectric constant (epsilon) values of 4 and 80. The interaction with the environment (either solvent or receptor) is schematically studied by positioning either two water molecules or one formamide or/and one formic add near the amide and the imidazole for few isomers. The medium polarization, through epsilon, and the solvation effect, through the interaction with the solvent molecules or the receptor side chains, stabilize the same isomers. Post-SCF calculations are performed at the CISD level, the first excited singlet and triplet states energies are determined, and the question of the wave-function stability is addressed. The results indicate the probability of a spin-orbit coupling with the first excited triplet state, thus opening the question of such a possibility within an enzyme active site.

OBJECTIVE: To analyse the frequency, type, and immunohistological features of clinical cutaneous vasculitis developing in patients with rheumatoid arthritis (RA) treated or not with methotrexate as well as their demographic, clinical and biological characteristics. METHODS: Ninety-one patients with RA receiving 9.5 mg/wk of methotrexate (MTX) were compared for an average observation time of 18 months to 130 matched patients with RA treated with various drugs excluding MTX. RESULTS: Whether receiving MTX or not, 5.4% of patients with RA developed a clinical cutaneous vasculitis. There were significant differences between both groups for 2 variables only: a higher percentage of polyneuropathies and a higher level of immune complex-plasma levels in non-MTX patients. The immunohistological analysis did not differentiate both groups. CONCLUSION: The percentage of cutaneous vasculitis that developed under MTX therapy was not different from that occurring as a natural complication of longstanding severe RA. [less ▲]

The beam-foil source can produce spectra of almost every ion and allows easy measurement of atomic lifetimes of excited levels. Beam-foil spectra have some unique characteristics that made them valuable tool for the term analysis of highly charged ions. As an example, we will describe the work undertaken at Liège on Ne IV and Ne V. Beam-foil is still the only general method for measuring the lifetime of atomic levels in highly charged ions. However, the accuracy of the classical beam-foil method is limited by the non-selective broadband excitation in the foil that populates almost all excitation levels up to very high energy and corrupts by cascading phenomena the normal single-exponential decay curves. We will describe some techniques that have been invented to obviate this infamous “cascading effect”, especially the beam-foil-laser spectroscopy method recently developed in our laboratory. We will present an overview of the beam-foil spectroscopy research performed at the University of Liège together with other recent trends in the field of fast-beam spectroscopy. [less ▲]

Photoionization by the high-redshift ultraviolet radiation background heats low- density gas before it falls into dark matter potential wells, and it eliminates the neutral hydrogen and singly ionized helium that dominate cooling of primordial gas at temperatures of 10(4)-10(5) K. We investigate the influence of photoionization on galaxy formation using high-resolution simulations with a one-dimensional, spherically symmetric, Lagrangian hydrodynamics/gravity code. We find that the presence of a photoionizing background suppresses the formation of galaxies with circular velocities v(circ) less than or similar to 30 km s(-1) and substantially reduces the mass of cooled baryons in systems with circular velocities up to v(circ) similar to 50 km s(-1). Above v(circ) similar to 75 km s(-1), photoionization has no significant effect. Photoionization exerts its influence primarily by heating gas before collapse; the elimination of line cooling processes is less important. We discuss the implications of these results for hierarchical theories of galaxy formation. [less ▲]

P300 and contingent negative variation (CNV) were recorded in depressive inpatients with and without history of suicide attempt. The results showed a significant reduction of P200, P300, and CNV and a significant increase of postimperative negative variation (PINV) in patients who had attempted suicide compared to patients with a negative history. Moreover, P300 amplitude was negatively related with the Suicidal Risk and the Hopelessness but not with the Hamilton scales. These results stress the need to differentiate clinical subgroups of patients to assess the psychophysiology of depression, and indicate that patients who attempted suicide exhibit lower cortical resources and poorer cortical performance than patients without history of suicide attempt.

In bean, potato, and Oenothera plants, the C encoded at position 4 (C-4) in the mitochondrial tRNA(GAA)(Phe) gene is converted into a U in the mature tRNA, This nucleotide change corrects a mismatched C-4-A(69) base pair which appears when the gene sequence is folded into the cloverleaf structure. C-to-U conversions constitute the most common editing events occurring in plant mitochondrial mRNAs. While most of these conversions introduce changes in the amino acids specified by the mRNA and appear to be essential for the synthesis of functional proteins in plant mitochondria, the putative role of mitochondrial tRNA editing has not yet been defined. Since the edited form of the tRNA has the correct secondary and tertiary structures compared with the nonedited form, the two main processes which might be affected by a nucleotide conversion are aminoacylation and maturation. To test these possibilities, we determined the aminoacylation properties of unedited and edited potato mitochondrial tRNA(Phe) in vitro transcripts, as well as the processing efficiency of in vitro-synthesized potato mitochondrial tRNA(Phe) precursors. Reverse transcription-PCR amplification of natural precursors followed by cDNA sequencing was also used to investigate the influence of editing on processing. Our results show that C-to-U conversion at position 4 in the potato mitochondrial tRNA(GAA)(Phe) is not required for aminoacylation,vith phenylalanine but is likely to be essential for efficient processing of this tRNA.

Objectifs : Etudier le profil de l'usage de médicaments chez les toxicomanes à l'héroïne Sujets et méthodes : 89 héroïnomanes, enrôlés dans un programme de maintenance par la méthadone en médecine de famille, ont fait l'objet d'une enquête. Les patients pharmacophiles et leurs préférences ont été identifiés par questionnaire. L'enregistrement d'interviews face à face semistructurés a permis de mettre en évidence le profil de 56 patients ainsi que le tableau clinique résultant de l'abus de médicament. Une revue bibliographique et une investigations auprès de praticiens de différents pays renforcent l'étude. Résultats : 60%(53/89) des consultants ont abusé de médicaments au moins une fois. Le Rohypnol™ (Flunitrazépam), un hypnotique puissant, est placé en premier choix comme succédané de l'héroïne par 66% de ces utilisateurs abusifs. " Etre en Roche " est une expression utilisée par les toxicomanes euxmêmes pour désigner le tableau clinique consécutif à la prise diurne d'un ou plusieurs (jusqu'à 30 c à 2mg par jour) comprimés de Rohypnol™, associé ou non à l'alcool. Un comprimé de Rohypnol™est appelé un " Roche " et un utilisateur compulsif un " Rocheman ". Le tableau clinique est caractérisé par un état d'obnubilation ( « Etre ravagé, pété, mort »), une dysarthrie, une sensation d'invincibilité, une perte d'inhibition avec possible passage à l'acte et agression suivis d'endormissement et d'amnésie antérograde totale. L'information concernant la dangerosité de ce produit n'a pas été diffusée . Le Rohypnol™ est une drogue de rue dans tous les pays étudiés. Conclusions : Le Rohypnol™ est une drogue dure, succédané de l'héroïne et un amnésiant puissant. Ce produit est dangereux par son pouvoir amnésiant et désinhibant.

Assessing the frequency of metritis shows the animal uterine health as well as the herd . The practitioner prefers to use vaginal examination. The great diversity and variation postpartum in germs responsible for uterine diseases make it difficult to interpret bacteriology.

Multispectral observations of the far ultraviolet Jovian aurora with the faint object camera (FOC) on board the Hubble Space Telescope are reported. They are used to describe and compare the morphology and the mean brightness of the H-2 Lyman and Werner bands observed at 153, 125, and 130 nm. It is shown that most of the emissions are confined inside the 6 R(J) O-6-GSFC auroral oval and fill a large fraction of the polar cap. During the similar to 50 hours time span of the observations following a very strong aurora, no bright are was observed along the oval mapping the 30 R(J) O-6 oval. Hydrogen emissions at 125 and 130 nm are observed down to 50 degrees N and somewhat below, a region not accessible to previous FOC observations at longer wavelengths.

Insulin action is crucial for the regulation of glucose metabolism. Insulin plays a key role in suppressing endogenous glucose production by the liver, both in fasting and postprandial states. Insulin is also necessary for the maintenance of normal rates of glucose oxidation and storage in insulin-sensitive tissues and for the prevention of excessive gluconeogenic substrate production. Various methods have been developed to assess insulin action in vivo, essentially at liver and muscle sites. Such methods evaluate the effect of exogenous or endogenous insulin, using respectively the open-loop approach (interruption of the feedback loop by inhibiting endogenous insulin secretion) or the closed-loop approach (mathematical modelling of the insulin-glucose feedback loop). Knowledge of the successive steps of cellular insulin action has markedly improved during the last ten years. Preceptor, receptor and postreceptor levels need to be considered since they may be affected in insulin-resistant states. This general progress in the understanding of insulin action in man improves our approach to the complex pathophysiology of non-insulin-dependent diabetes mellitus and opens up new prospects for treatment of the insulin-resistant syndrome which is associated with several atherosclerotic risk factors.

Pea starch, hulls and cotyledon inner fibres, isolated from pea seeds, were incorporated in N-free diets, on a NDF-content basis, in order to study their effect on the ileal endogenous amino acid (AA) excretion in the growing pig. Maize starch and wood cellulose were selected as references. The inner fibrecontaining diet was also supplemented with enzymatically hydrolysed casein (EHC) in order to test the peptide alimentation method on a diet containing a fibre source with a high water-holding capacity (WHC = 10.9 g water g-' DM). The fibres were also analysed by different methods (crude fibre, NDF, ADF, enzymatic-gravimetric method, Englyst method). The fibre content of the inner fibre fraction varied widely from one method to another and ranged from 109 g crude fibre to 480 g AOAC fibre kg-' DM. Compared to the 'maize starch + wood cellulose' diet (11.0 g AA excreted kg-' DM intake), pea starch had no effect on ileal AA losses (9.6 g), whereas pea hulls slightly increased them (14.2 g). The AA excretion dramatically increased with the incorporation of inner fibres (28.0 g), because of their very high WHC. The addition of EHC increased the output (48.0 g) further, at a level that can hardly be explained only by an increase of the endogenous secretions. The results suggest that the NDF content of grain legume products is not indicative of their effect on the ileal endogenous AA losses in pigs and that the physiological effects of fibres along the gastrointestinal tract are due to both their chemical and physical properties.

Human apolipoprotein A-II (apo A-II) consists of three potential amphipathic helices of 17 residues each, which contribute to the lipid-binding properties of this apolipoprotein. The conformation and lipid-binding properties of these peptides, either as single-helix or as two-helix peptides, were investigated by turbidity, fluorescence, electron-microscopy and circular-dichroism measurements, and are compared in this article. The lipid affinity of shorter C-terminal segments of apo A-II was compared with those of the single-helix or two-helix peptides, to define the minimal peptide length required for stable complex formation. The properties of the apo-A-II-(13-48)-peptide were further compared with those of the same segment after deletion of the Ser31 and Pro32 residues, because the deleted apo-A-II-(13-30)-(33-48)-peptide, is predicted to form a long uninterrupted helix. The single helices of apo A-II could not form stable complexes with phospholipids, and the helix-turn-helix segment spanning residues 13-48 was not active either. The apo-A-II-(37-77)-peptide and the apo-A-II-(40-73)-peptide could form complexes with lipids, which appear as discoidal particles by negative-staining electron microscopy. The shortest C-terminal domain of apo A-II able to associate with lipids to form stable complexes was the apo-A-II-(40-73)-peptide, which consisted of the C-terminal helix, a beta-turn and part of the preceding helix. The shorter apo-A-II-(49-77)-peptide, and the helical apo-A-II-(13-30)-(33-48)-peptide, could also associate with phospholipids. The complexes formed were, however, less stable, as they dissociated outside the transition temperature range of the phospholipid. These data suggest that the C-terminal pair of helices of apo A-II, which is the most hydrophobic pair, is responsible for the lipid-binding properties of the entire protein. The N-terminal pair of helices of apo A-II at residues 13-48 does not associate tightly with lipids. The degree of internal similarity and the cooperativity between the helical segments of apo A-II is thus less pronounced than in apo A-I or apo A-IV. The N-terminal and C-terminal domains of apo A-II appear to behave as two distinct entities with regard to lipid-protein association. [less ▲]

The superconductivity fluctuation contribution kappa(B) to the thermal conductivity of a Bi2Sr1.8Ca1.2Cu2O8+y polycrystal is extracted from precise experimental data. The crossover from two-dimensional (2D) to 3D behavior theoretically predicted by Varlamov and Livanov is well marked. The crossover temperature T-VL and the amplitude of the fluctuation contribution lead to realistic values for the interlayer coupling energy J(C) and the transport relaxation time tau near T-c.

Platelet-activating factor (PAF) may play a role in the pathophysiology of asthma but controversies exist about bronchial responsiveness toward this mediator in asthma. We have compared the variations in the specific conductance (sGaw) and forced expiratory volume in one second (FEV1) in 12 asthmatics and 12 normal subjects after inhalation of doubling doses of PAF (15-120 micrograms) and methacholine (18 to at least 144 micrograms). In order to take into account a possible tachyphylaxis, we compared PAF dose-response curves performed on one day with the curves obtained by giving the same doses separately on different days. Repeated inhalations of doubling doses of PAF caused sGaw and FEV1 to plateau after the second dose in each group, whereas methacholine provoked a dose-related decrease in sGaw and FEV1. A dose-dependent decrease in the functional indices was restored when the different doses of PAF were administered on separate days. In both groups, the fall in sGaw after inhalation of 60 micrograms as a single dose was higher than that achieved when this dose was given during a full bronchial challenge. The falls in sGaw and FEV1 after PAF inhalation were significantly higher in the asthmatics than in the normal subjects. The provocative dose of PAF causing a 35% fall in sGaw (PD35,sGaw) PAF was only twofold lower in the asthmatics than in the normal subjects (p < 0.05), while it was 11 fold lower for methacholine (p < 0.001). When the PD35,sGaw values were compared, PAF was found on a molar basis to be 33 fold more potent than methacholine in the normal subjects, but only fivefold more potent in the asthmatics (p < 0.05). The percentage falls in FEV1 (calculated by interpolation) for a 35% fall in sGaw, were greater in asthmatics than in normals both for methacholine (p < 0.05) and PAF (p = 0.09). Our results demonstrate a tachyphylaxis after inhalation of platelet-activating factor in normal subjects and asthmatics, and show that asthmatics develop a greater bronchial obstruction than normal subjects even if methacholine is more sensitive than platelet-activating factor at discriminating between the two groups.

To explore the pathophysiology of respiratory failure in an experimental pneumonia, a Pasteurella haemolytica broth culture was injected intratracheally into 12 calves, which were then studied over a period of 10 h. Measurements were made of inspired minute ventilation VE), ventilatory pattern [inspiratory time (TI), expiratory time (TE), respiratory rate (RR) and tidal volume (VT)], transdiaphragmatic pressure (Pdi), occlusion pressure at the airway opening 100 milliseconds after onset of inspiration (Pawo100ms), arterial blood gas tensions and pH and recorded diaphragmatic electromyogram (EMGdi) and rectal temperature (Tr). On and after the third hour after inoculation, the animals varied in respect of clinical signs, Tr, RR, VE, Pawo100ms/EMGdi, and arterial gases and pH. In benign cases, diminished alertness, laboured respiration and fall of arterial oxygen pressure (PaO2) worsened up to 7 h after inoculation, but then progressively improved, VE being maintained at approximately 150% baseline throughout the study (10 h). Neither arterial carbon dioxide pressure (PaCO2) nor pH was altered. Moderate cases resembled benign cases in respect of laboured respiration, VE, PaO2 and PaCO2; however, pH was at first maintained at preinoculation levels, but declined thereafter. In severe cases, the animals were drowsy between hours 3 and 7, and became comatose between hours 8 and 10; in contrast to both benign and moderate cases: (1) RR was reduced by hour 5, (2) there was no trend towards recovery of PaO2 and pH, (3) VE, Pdi, Pawo100ms and Pawo100ms/EMGdi were severely decreased, and (4) PaCO2 increased. These results suggest that pneumonia does not alter ventilatory neuromuscular pump function in calves, unless concomitant cardiovascular collapse occurs. It is not clear whether fatal ventilatory failure is caused mainly by deterioration in ventilatory muscle fibre processes or structures, altered central nervous system adjustment of ventilatory timing, or cardiovascular dysfunction. However, inspiratory pressures fall when excitation to the diaphragm is still growing, which suggests peripheral respiratory muscle fatigue. [less ▲]

Production of beta-lactamase was detected by the nitrocefin test in 48% of the isolates. At NCCLS-recommended breakpoints, more than 90% of isolates were susceptible to amoxycillin/clavulanate, ticarcillin/clavulanate, piperacillin/tazobactam, imipenem, chloramphenicol and metronidazole but only 77%, 72% and 48% to cefoxitin, clindamycin and penicillin, respectively. In comparison with the results of a similar survey conducted in 1987 no major changes in susceptibility were observed except for the susceptibility to clindamycin that declined from 83% to 72% overall, and from 83% to 66% in the B. fragilis group. Furthermore one isolate of Clostridium clostridioforme was found produce beta-lactamase and few B. fragilis group isolates showed reduced susceptibility to metronidazole. [less ▲]

Four GUC triplets in the coding region of the MRNA of interleukin 6 (IL-6) were examined for their suitabilty to serve as a target for hammerhead ribozome-mediated cleavage. This selection procedure was performed with the intention to downregulate IL-6 production as a potential treatment of those diseases in which IL-6 overexpression is involved. Hammerhead ribozymes and their respective short synthetic substrates (19-mers) were synthesized for these four GUC triplets. Notwithstanding the identical catalytic core sequences, the difference in base composition of the helices involved in substrate binding caused substantial variation in cleavage activity. The cleavage reactions on the 1035 nucleotide IL-6 mRNA transcript revealed that two ribozymes were able to cleave this substrate, showing a decrease in catalytic efficiency to 1/30 and 1/300 of the short substrate. This study indicates that the GUC triplet located at nucleotide 510 of the mRNA of IL-6 is the best site for hammerhead ribozyme-mediated cleavage. We suggest that in future targeting of chemically modified hammerhead ribosomes for cleavage of IL-6 RNA should be directed at this location. [less ▲]

The effects of atmospheric ammonia (NH3) on the nasal and tracheal mucosa of pigs were investigated by morphometric and functional methods. Pigs were exposed to four concentrations of NH3 [5 (control), 25, 50 and 100 ppm] for 6 days in a specially designed air-pollutant exposure chamber. Samples were taken from the turbinates and the trachea, and the respiratory mucosa was examined by light and scanning electron microscopy. Dose-response curves to carbachol and isoproterenol were constructed using isolated strips of tracheal smooth muscle, with or without epithelium. In pigs exposed to ammonia, considerable mucosal injuries were observed in the turbinates but not in the trachea. The number of neutrophils in the epithelial layer and in the lamina propria, and epithelial hyperplasia were closely and significantly correlated with the concentrations of ammonia (r = 0.894, p < 0.001; r = 0.727, P < 0.001; and r = 0.818, p < 0.001, respectively). Except for the lamina propria, all these changes were significant (p < 0.05) at ammonia concentrations as low as 25 ppm. The percentage of the surface of the turbinate mucosa that was ciliated tended to decrease with increasing ammonia concentration (r = 0.439, p < 0.082). Ammonia induced smooth-muscle hyperresponsiveness to carbachol with a close linear correlation between individual values of the carbachol-induced maximal effect and the NH3 concentrations (r = 0.526, p < 0.003). While mechanical destruction of the epithelium induced an increase in Emax in the control group, no difference was observed between the intact and denuded strips from animals exposed to ammonia. The response to isoproterenol was not influenced by ammonia. It was concluded that quantitative histological analysis of the inflammatory infiltration and epithelial hyperplasia in the turbinates is a useful tool for quantifying the effects of atmospheric pollutants in pigs; a 6-day exposure to ammonia induces nasal irritation and functional disturbances of the tracheal smooth-muscle contractions at concentrations as low as 25 ppm [less ▲]

In the Belgian Blue Cattle breed, coat color variation is mainly under the influence of a single autosomal locus, the roan locus, characterized by a pair of codominant alleles: r + (black) and R (white). Heterozygous r + R animals have intermingled black and white hairs, yielding the ``blue'' phenotype typical of the breed. Major interest for the roan locus stems from its pleiotropic effect on fertility, owing to the critical role of the R allele in the determinism of White Heifer Disease. We describe the linkage mapping of the roan locus to bovine Chromosome (Chr) 5, in the interval between microsatellite markers BPI and AGLA293, with an associated lodscore of 11.2. Moreover, we map a candidate gene, the Steel locus coding for the mast cell growth factor, to bovine Chr 5. [less ▲]

Current methods for evaluating the mediastinum include chest radiography, computed tomography (CT) or magnetic resonance (MR) imaging and mediastinoscopy. Despite advances in morphologic imaging, some lung cancer patients are found to have unresectable disease at surgery. In contrast to CT scan or MR imaging, which depend primarily on anatomic and morphological criteria, positron emission tomography (PET) with 18fluorodeoxyglucose (FDG) depends mainly of the metabolic characteristics of a tissue for the diagnosis of disease. We perform a prospective study to compare FDG-PET and CT of the thorax in the presurgical assessment of the mediastinum in patients with newly diagnosed non-small cell lung cancer. Thirty patients have been included. CT and PET-scans were interpreted separately and results were compared to surgical staging during thoracotomy. In assessing mediastinal involvement, CT scan had a sensitivity of 56% and a specificity of 64%. For diagnosis mediastinal nodal disease, FDG-PET was 87% sensitive and 78% specific. Its positive predictive value was 82%, and the negative value was 83%. In conclusion, our preliminary results show that FDG-PET appears more accurate than CT in staging of mediastinal non-small cell lung cancer. [less ▲]

These substitutions strongly interfere with TIM subunit association, since these mutant TIMs appear to exist as compact monomers in dynamic equilibrium with dimers. In kinetic studies, the M14Q mutant exhibits significant catalytic activity, while the R98Q enzyme is inactive. The M14Q enzyme is nevertheless much less active than unmutated hTIM. Moreover, its specific activity is concentration dependent, suggesting a dissociation process in which the monomers are inactive. In order to determine the conformational stability of the wild-type and mutant hTIMs, unfolding of all three enzymes was monitored by circular dichroism and tryptophan fluorescence spectroscopy. In each case, protein stability is concentration dependent, and the unfolding reaction is compatible with a two-state model involving the native dimer and unfolded monomers. The conformational stability of hTIM, as estimated according to this model, is 19.3 (+/-0.4) kcal/mol. The M14Q and R98Q replacements significantly reduce enzyme stability, since the free energies of unfolding are 13.8 and 13.5 (+/- 0.3) kcal/mol respectively, for the mutants, A third mutant, in which the M14Q and R98Q replacements are cumulated, behaves like a monomer. The stability of this mutant is not concentration-dependent, and the unfolding reaction is assigned to a transition from a folded monomer to an unfolded monomer. The conformational stability of this double mutant is estimated 2.5 (+/-0.1) kcal/mol. All these data combined suggest that TIM monomers are thermodynamically unstable. This might explain why TIM occurs only as a dimer. [less ▲]

Testis regression was induced in male Syrian hamsters by chronic exposure to diethylstilbestrol (DES), an estradiol-1713 agonist. Experimental groups (n = 4-5) were killed at increasing time intervals over a period of 6 mo after initiation of treatment. Apoptosis in testes was demonstrated by in situ analysis of DNA fragmentation. Cell proliferation was monitored by immunostaining nuclei of S-phase cells after pulse labeling with 5-bromo-2'-deoxyuridine. Levels of FSH and testosterone, measured by RIA, fell rapidly in DES-treated hamsters. In parallel, testis weight and seminiferous tubule area underwent an 80% decrease during the first 2 wk of DES administration. The composition of seminiferous epithelium was also drastically affected by DES, since it became progressively confined to Sertoli cells, spermatogonia, and spermatocytes. Testis regression was associated with an important increase of apoptosis, which started 3 days after the beginning of DES administration. Apoptosis was still 10- to 50-fold higher than in control testes by the end of treatment; it affected primarily spermatocytes and, to a much lesser extent, spermatogonia. Cell proliferation was not inhibited by chronic DES administration. In conclusion, these data indicate that apoptosis can by itself account for estrogen-induced testis regression. [less ▲]

Osteoporosis is a medical, social and economical problem for developed countries. Prevention remains the only realistic approach to reduce the burden related to this disorder. Primary prevention of osteoporosis is based on efforts to reach a maximal peak bone mass at the end of the growth period and, subsequently, at the time of menopause. No pharmacological intervention is considered at this stage. Biologically, hormone replacement therapy induces a correction of the biochemical changes observed in markers of bone remodeling at the time of the menopause. A systematic screening of asymptomatic postmenopausal women followed by the induction of hormonal replacement therapy in high risk subjects appears to be an interesting cost/benefit strategy in terms of reasonable attribution of health resources. Nasal administration of calcitonin fully prevents the trabecular bone loss observed during the first years of menopause. Notwithstanding, the exact dose of nasal calcitonin able to prevent bone loss remains to be fully elucidated. Bisphosphonates inhibit bone resorption. Tiludronate prevents trabecular postmenopausal bone loss. The use of selectif estrogen receptor modulators is based on a possible differential action of these molecules, at the level of the estrogenic receptors, depending of the tissue considered. Several direct inhibitors of osteoclastic resorption are also under development. Their main target is either to prevent the linkage of osteoclasts to the bone matrix or to prevent the acidification of bone matrix required to induce the resorption process. [less ▲]

Freeze-drying of polylactide solutions in 1,4-dioxane has been studied as a way to produce microcellular foams. The thermally induced phase separation has been studied in relation to several processing and formulation parameters. The effects of polymer concentration, chain stereoregularity, polymer molecular weight and cooling rate have been investigated in connection with the porous morphology and the physico-mechanical characteristics of the final foams. As a rule, bundles of channels are formed with a diameter of ~100 μ.m. They have a preferential orientation that fits the cooling direction. A porous substructure (~10 μm) is observed in the internal walls of the tubular macropores. Variations in this general porous morphology-and particularly in the porosity, density, solvent residue, mechanical resistance and degree of regularity in the spatial organization of pores-have been observed when polymer concentration in 1,4-dioxane and polylactide stereoregularity are changed. As expected, cooling rate has a strong effect on the foam morphology, which is essentially controlled by the solvent crystallization. Pores are nothing but the fingerprints of 1,4-dioxane crystallites. [less ▲]

A multicentre, double-blind, randomized study was conducted in patients with rheumatoid arthritis (RA) in order to compare the efficacy and safety of two different doses of meloxicam, a new preferential cyclooxygenase-2 (COX-2) inhibitor. Four hundred and twenty-three patients were randomized to receive once-daily oral meloxicam 7.5 mg (n = 216) or meloxicam 15 mg (n = 207) for 3 weeks. The Ritchie joint index and pain in the morning were significantly improved versus baseline (P < 0.001) in both groups. There were no significant differences between the effects of each dose with respect to these measures nor with respect to final assessment of global efficacy by the patients. However, the 15 mg dose was associated with a significantly (P < 0.05) better effect on morning stiffness and grip strength. No differences between the doses were observed with regard to the other secondary efficacy parameter (pain at night, body weight and erythrocyte sedimentation rate). Both doses of meloxicam were well tolerated. There were no differences between the doses with respect to global tolerance as assessed by the patient and the patients, 'general condition'. In conclusion, meloxicam at a once-daily dose of either 7.5 or 15 mg is well tolerated and effective in the treatment of patients with RA. [less ▲]

A all in vitro cloning technique was developed in which the reconstituted embryos from the first cycle nuclear transfer (cloning) were used as blastomere donor for the second cycle nuclear transfer (recloning). Such method permitted to produce 14.5% of morulae and 14.9% of blastocysts after the first and second cycles of nuclear transfer, respectively. The rates of birth obtained after transfer of such embryos were 21.4% et 20.8% for first and second cycles respectively, corresponding to 6 et 5 calves for 28 et 24 transferred embryos. Unfortunately, gestation pathologies and an increase of birth weights were observed. It seems that the in vitro presence of gametes and/or embryos may be responsible of an alteration in the control of gene expression. [less ▲]

This study was undertaken to evaluate the efficacy and safety of an intrauterine device designed for endometrial ablation by Nd-YAG laser interstitial hyperthermy. Eight hysterectomy specimens were treated in vitro with an output power of 30 W for 5 minutes; tissue temperatures, recorded by thermocouples, were plotted to draw time-temperature and time-distance curves. As a preliminary series, ten patients were treated, with the first five subjected to local temperature monitoring; all ten were followed-up for 6-17 months. Immediate and delayed (6 weeks) histologic data were obtained. The intramural temperature at 6 mm from the fibers ranged from 55-60C). In vivo, the cooling effect of the arterial blood flow lowered the serosal temperatures under 41C. The histologic data and the hysterographic pictures suggest that endometrial ablation was effective. This new device does not require distending medium, hysteroscopic control, or high-powered Nd-YAG laser machines. Preliminary long-term results suggest that the device could be used for endometrial ablation. [less ▲]
