Climatological analyses of a historical data base have been carried out with the aim of reconstructing the three-dimensional temperature and salinity fields in the Mediterranean Sea. Seasonal and monthly distributions of hydrographic properties have been computed by a variational inverse method as an alternate to the standard Gandin (1969; Objective analysis of meterological fields, Israeli Program for Scientific Translation, Jerusalem) procedure. The spline solutions of the minimization problem are demonstrated to be numerically and theoretically equivalent to field estimates obtained by conventional objective analysis. The application of a finite-element technique allows analysis to be performed in the model space rather than in the observational space, which substantially improves the numerical efficiency of the procedure. The parameters of the scheme are adjusted according to the statistics of the climatological data. The results,realized as gridded data sets (horizontal resolution of 0.25 degrees), show some trends in seasonal variability affecting the properties of water masses. As expected, the upper layer is subject to a well-defined seasonal signal affecting both the temperature and salinity fields. Error maps, reflecting the degree of uncertainty in the analyses, have been systematically produced. The present work is conceived as a basic support to more advanced studies such as diagnostic calculations, initialization of dynamical models, assimilation of hydrological data into primitive equation models, or planning of experimental surveys. New versions of the climatological fields will be released as data are added to the historical data base. Copyright (C) 1996 Elsevier Science Ltd. [less ▲]

Les adénomes hypophysaires gonadotropes qui sont parmi les plus fréquents, ont été identifiés récemment; on estime aujourd'hui qu'environ 80 % des adénomes hypophysaires dits non-sécrétants sont en fait gonadotropes. Étant donné l'absente de symptomatologie spécifique, ils ne sont souvent reconnus que lorsqu'ils sont volumineux, ayant déjà entraîné un syndrome neurologique, une compression du chiasma optique. Dans la plupart des cas il est possible de les identifier grâce aux produits de sécrétion ou encore par méthodes d'immunohistochimie ou encore par la détection de l'ARN messager correspondant aux sous-unités hormonales. Le traitement reste essentiellement neuro-chirurgical (chirurgie trans-sphénoidale) car, dans la plupart des cas, les agonistes dopaminergiques et les analogues agonistes ou antagonistes de GnRH sont inefficaces.

Several lines of evidence suggest that dopamine plays a role in the pathophysiology of obsessive-compulsive disorder (OCD). Indeed, some trials have shown the efficacy of neuroleptic addition in the treatment of OCD patients. In this study, we assessed the growth hormone (GH) response to 0.5 mg apomorphine(sc) in 8 drug-free inpatients (6 male, 2 female; mean age +/- SD = 34.7 +/- 12.6) meeting DSM-III-R criteria for OCD without major depression and compared their responses with those of 8 healthy male volunteers (mean age = 27.1 +/- 8.5). The groups did not differ in their mean GH peak response: 12.4 +/- 9.7 ng/mL in OCD patients versus 21.1 +/- 14.2 ng/mL in normal controls (F = 0.9, df1, 14, P = 0.37). These results do not support the hypothesis of dopaminergic overactivity in OCD. In fact, the completely blunted GH response to apomorphine in 2 OCD patients suggests the biological heterogeneity of OCD. Some dopaminergic disturbances could be observed in patients with comorbid diagnoses or patients unresponsive to serotonin reuptake inhibitors, but the results of this study require confirmation from a larger sample with a precise assessment of comorbidity.

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.

Nuclear transfer was used to study nuclear reprogramming of fetal diploid bovine germ cells collected at two stages of the fetal development. In the first case, germ cells of both sexes were collected during their period of intragonadal mitotic multiplication at 48 days post coitum (d.p.c.). In the second case, only male germ cells were collected after this period, between 105 and 185 d.p.c. Isolated germ cells were fused with enucleated oocytes. Reconstituted embryos were cultured in vitro and those reaching the compacted morula or blastocyst stage were transferred into synchronous recipient heifers. Of 511 reconstituted embryos with 48 d.p.c. germ cells (309 males and 202 females), 48% (247/511 ) cleaved; 2.7% (14/511 ) reached the compacted morula stage and 8 of them the blastocyst stage (1.6%). No difference was observed between sexes. All 14 compacted morulae/blastocysts were transferred into 6 recipients and one pregnancy was initiated. This recipient was slaughtered at Day 35 and an abnormal conceptus (extended trophectoderm and degenerated embryo) was collected. Its male sex, genetically determined, corresponded to that of donor fetus. Of 380 reconstituted embryos with male 105 to 185 d.p.c. germ cells, 72.1% (274/380 ) cleaved, 2.1% (8 380 ) reached the compact morula stage and 7 of these the blastocyst stage (1.8%). Three blastocysts and one morula were transferred into 4 recipients. Two became pregnant at Day 21 but only one at Day 35 which aborted around Day 40. Our results show that the nucleus of diploid bovine germ cells of both sexes can be reprogrammed. However, in the absence of further development of these reconstituted embryos, nuclear totipotency of bovine diploid germ cells remains to be evidenced. [less ▲]

In a first experiment, performances and carcass quality of fattening pigs kept either on a litter with sawdust, on straw or on slatted floor were compared. Three batches of 17 pigs were kept on each floor type. Pens with litter were not cleaned until the end of the third fattening period. On average 100 kg of sawdust or 49 kg of straw were used per pig. The growth rate of pigs on litters was higher (P < 0,01) than that of pigs on slatted floor : 739 g/d on sawdust, 745 g/d on straw and 686 g/d on slatted floor. Carcass quality at slaughter was not different according to the floor type. The peak shear force of the M. Longissimus dorsi was higher for pigs kept on straw than for the 2 other groups. In a second experiment, 97 weaners, 4 weeks old, were divided in 3 groups on 3 floor types : a deep litter with sawdust, a deep litter with sawdust mixed with straw and a slatted floor. Between 4 and 10 weeks of age, the growth rates of pigs were different (P < 0,05) according to the 2 litters : 438 g/d on the deep litter with straw and sawdust, 397 g/d on sawdust and higher (P < 0,001) than that on slatted floor (273 g/d). Pigs on slatted floor were however disadvantaged by a lower health status in the breeding pig house. [less ▲]

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. Uterine diseases are all the more frequent as the interval between calving and clinical examination is shorter, therefore the practitioner screening needs to be done as soon as possible. This recommendation is valid for the primiparous dairy cow as well as the suckler cow [less ▲]

An inheritable muscular hypertrophy was recently described in sheep and shown to be determined by the callipyge gene mapped to ovine chromosome 18. Here, the callipyge phenotype was found to be characterized by a nonmendelian inheritance pattern, referred to as polar overdominance, where only heterozygous individuals having inherited the callipyge mutation from their sire express the phenotype. The possible role of parental imprinting in the determinism of polar overdominance is envisaged. [less ▲]

BACKGROUND: The gastrin gene is known to be expressed in all classes of bronchogenic carcinomas. Furthermore, high levels of gastrin have been reported in both the bronchoalveolar lavage (BAL) fluid and serum of patients with lung cancer. Based on these preliminary data a study was conducted to evaluate the usefulness of gastrin measurements in the diagnosis and staging of lung cancer. METHODS: Thirty-five patients with lung cancer (26 non-small cell (NSCLC) and nine small cell (SCLC)) and 25 patients with chronic obstructive pulmonary disease underwent fibreoptic bronchoscopy and BAL. Gastrin levels were determined in both BAL fluid and the serum and compared with each other and with staging. RESULTS: No difference was found between the gastrin levels in the BAL fluid or serum of the study groups. There was no correlation with the stage in NSCLC and no correlation was found between the gastrin levels in the serum and the BAL fluid. A significant difference was seen in gastrin levels in BAL fluid between extensive and limited SCLC (p < 0.05). CONCLUSION: There is no evidence of clinical usefulness for gastrin measurements in lung cancer. [less ▲]

We report a patient with poor-prognosis myelodysplastic syndrome (MDS) after successful treatment of lymphoma, who was given an allogeneic BMT, engrafted and achieved complete remission, but later had a relapse of his MDS with complete disappearance of donor haemopoiesis. After two episodes of CMV pneumonia and continued prophylactic use of ganciclovir thereafter, he experienced a spontaneous complete disappearance of all signs of MDS, including myelofibrosis, and a complete return to donor haemopoiesis. This case is the first one to suggest a graft-versus-leukaemia effect (GVL) in MDS patients. It depicts the complex relationship between GVL, graft-versus-host disease (GVHD) and graft rejection. It could also constitute a clinical illustration of the possible antileukaemic effect of CMV infection and its treatment with ganciclovir. [less ▲]

Blanching of Brussels sprouts before freezing induces chemical, enzymatical and physico-chemical modifications. This blanching study was made at three temperatures (in water at 90 degrees C and 95 degrees C, in steam at 105 degrees C), The glucosinolate and glucose contents decrease when the technological treatment is extended. These losses are higher in water blanching, especially for external leaves, The myrosinase activity is reduced when treatment time and temperature increase. The peroxydase which is more thermoresistant than myrosinase is a good test for measuring inactivation of enzymes during the industrial blanching. Variations of the colour (green) are larger for external leaves than in the middle of the material. After two minutes of blanching, a hardening of Brussels sprouts is observed hut, after that time, the hardness decreases. [less ▲]

Characterized the behavioral and pharmacological mechanisms associated with cocaine potentiation of apomorphine (AP)-induced gnawing (AIG) in male C57BL/6J mice. Results showed that (-)-cocaine enhanced AIG at doses devoid of effects on gnawing when given alone; (+)-cocaine or (-)-cocaine methiodide were also devoid of effects. Lidocaine, a local anesthetic without prominent dopaminergic actions, augmented the gnawing response to AP without increasing climbing or gnawing when given alone. (+)-Amphetamine enhanced AIG gnawing but only at a high dose that increased gnawing by itself. The selective dopamine (DA) uptake blocker, GBR 12909, augmented AIG by itself; however, it increased climbing at doses that augmented the gnawing response. These data indicate that the cocaine-augmented gnawing response to AP may be due to blockade of DA uptake and or the local anesthetic actions of cocaine.

A 73-year-old man developed an ill-defined fatal vasculitis involving the central nervous system. The case report was published as a clinicopathologic exercise in February 1995 in The New England Journal of Medicine.(1) We restudied the pathologic material and found both varicella tester virus (VZV) DNA and VZV-specific antigen, but not herpes simplex virus (HSV) or cytomegalovirus (CMV) DNA or HSV- or CMV-specific antigen, in three of the five cerebral arteries examined.

A search for VZV should be conducted in cases of vasculitis when both the central and peripheral nervous systems are involved, when focal narrowing is present in large arteries, when brain imaging reveals infarction in gray and white matter, both deep and superficial, and when white matter is disproportionally involved.

The present paper deals with an analysis of metric (cranial measurements) and non metric (epigenetic cranial characters) variation in black rat populations from S. Miguel and Terceira islands compared to a continental sample. Assuming the Azorean rats originate from the European continent, we tested the similarity between the samples, considering only adult and subadult animals. Having verified that there was no sexual dimorphism in the characters studied, we computed discriminant functions and made a PCA with the most discriminant variables. The three samples are clearly separated by these functions, the Azorean rats showing a larger general skull size and differing between the two islands. The Mean Measure of Divergence (MMD), based on non metric cranial traits frequencies, was also used to express the interpopulational differences: the rats of Terceira differ significantly either from the continental ones or from those of S. Miguel. Finally, the possible origin of these differences is disussed. [less ▲]

Many questions are still unanswered about the biogeography and the origin of the wood mouse in the Mediterranean area, namely on the islands where some giant forms are described. In order to characterize the genetic structure of these insular populations and their level of morphological differentiation, 232 animals originating from 30 localities situated on several western Mediterranean islands and on the continent, either along the sea coast or more inland, were trapped. Their skulls were measured and their mtDNA purified and analysed by RFLP techniques. The wood mice living on small islands are generally bigger than their relatives living on the continent whereas the size of those living on larger islands is quite the same. This kind of insular gigantism ought to be more an adaptive response to peculiar insular environmental conditions (particularly a lower predation pressure) than a consequence of a founder effect. The mtDNA of the wood mice from north-eastern Spain belongs to the previously identified northwestern group (Michaux et al., 1996). Consequently, the Pyrenees are not a biogeographic barrier to the wood mouse. The Sicilian mice, which are genetically different from all the other west European or north-African animals, are morphologically similar to the Sardinian and Italian ones. [less ▲]

We measured the AC susceptibility of magnetically textured (123) 80%/211(20%) DyBaCuO composite in a special set-up in order to enhance the intergrain contribution. The synthesis process led to very clean ''weak links'' at grain boundaries. At the percolation threshold bulk shielding paths were such that the intergrain critical current density J(c) was above 10(5) A/cm(2). The field dependence of J(c) was understood through an analytical form indicating a distribution of currents similar to the law of clusters at fracture/percolation thresholds. [less ▲]

The dissociative ionization of C2H2, C2D2 and C2HD is presented in this work. Excepting the H2+ formation, all dissociation channels are thoroughly investigated by electron impact. The translational energy distribution as a function of the impinging electron energy and the appearance energy as a function of the translational energy are measured for all fragment ions. KE versus AE diagrams are obtained and the isotope effect is examined. All observed thresholds are analyzed in detail and dissociation mechanisms are proposed. For the C2H+ ion the PIPECO technique has also been used. From these discussions the H-C2H, HC-CH and H-C2 binding energy values are proposed, i.e. 5.33+/-0.23 eV, 9.83+/0.10 eV and 5.44+/-0.40 eV respectively. The fragmentation path leading to C+, CH2+ and C2+ are discussed in terms of dissociation mechanisms involving the transient vinylidene structure of the molecular ion as an intermediate. [less ▲]

The colonisation of Europe by the black rat (Rattus rattus) dates back only to the Roman times. This rodent is now widespread all over the continent as well as on many islands where it was introduced by man. In some instances, insular populations are morphologically differentiated by their greater size. In order to study the possible origin of these insular populations, rats were caught on many Mediterranean (Sicily, Sardinia, Lavezzi, Corsica, Elba, Porquerolles) and Atlantic islands (Ré, Oléron, Azores) and compared to animals from continental Europe (Spain), and Africa (Tunisia, Benin). Their karyotype was determined and their mtDNA restriction patterns studied using the HAE III and RSA I endonucleases and a polyacrylamide gel electrophoresis. These patterns appear very similar to each other though one of them is specific to the African animals, probably indicating that Europe and Africa were colonised by different strains. [less ▲]

Thermography studies pictures recorded from radiant thermal emissions of a body. This paper analyses several measurement conditions in order to make thermographic unit reliable, ie the effects of distance and position of the camera, the color, lenght and power. Moreover, the effects of the site on cutaneous temperature measurements were studied in exercising horses. It can be concluded that infrared thermography is a technical to measure skin temperature which requires a few conditions to be respected. Moreover, it is a sure, simple and fast method. The ideal site for measuring skin temperature inexercising horses is the neck because of its vascularisation. [less ▲]

Homeodomain-containing proteins are transcription factors that regulate the co-ordinated expression of multiple genes involved in development, differentiation and malignant transformation. In an attempt to characterize expressed homeobox (HOX) genes in breast cancer cells, we cloned two distinct HOXC6 transcripts from an MCF7 cDNA library, Interestingly, one of them represents a new HOXC6 mRNA encoding a homeodomain-containing protein harbouring a unique N-terminal sequence. Moreover we demonstrate that this HOXC6 transcript is less abundant in human breast cancer cells than in non-tumorigenic cell lines, is detected in breast carcinomas and adjacent tissues and is expressed in a variety of human tumours. In addition, transient co-transfection experiments illustrated that both HOXC6 transcripts encode gene products that repress transcription from a HOX binding sequence in MDA-MB231 cells and co-operate with other HOX gene products such as HOXB7 on their target genes. Taken together, our results suggest that HOXC6 proteins might contribute to the breast cell phenotype through co-operative interactions with other HOX-derived proteins and repression of their target genes.

Since the end of the sixties, number of studies have put in obviousness that the short-term memory span of mentally retarded subjects remains largely below the level expected regarding their mental age and their chronological age. Mackenzie and Hulme (1987) and Hulme and Mackenzie (1992), for example, showed that verbal short-term memory abilities of mentally retarded subjects do not develop at the same rate than other cognitives aspects. These results provide important information on the development of memory span in those subjects but do not provide information on the functioning of the different components of their verbal short-term memory. We conducted several experiments in order to supply with this deficit and to describe the functioning of the verbal short-term memory in a group of Down's syndrome subjects. Our data put in obviousness the similarity of verbal short-term memory's functioning in Down's syndrome subjects and in normal children (phonological similarity effect and word length effect). The absence of a significant correlation between articulation rate and memory span in Down's syndrome people (like in less than 6 years old normal children, see Gathercole et al., 1993, 1994) leads us to discuss a central point of the working memory model (Baddeley, 1986).

The biguanide metformin (dimethylbiguanide) is an oral antihyperglycaemic agent widely used in the management of non-insulin-dependent diabetes mellitus (NIDDM). Considerable renewal of interest in this drug has been observed in recent years. Metformin can be determined in biological fluids by various methods, mainly using high performance liquid chromatography, which allows pharmacokinetic studies in healthy volunteers and diabetic patients. Metformin disposition is apparently unaffected by the presence of diabetes and only slightly affected by the use of different oral formulations. Metformin has an absolute oral bioavailability of 40 to 60%, and gastrointestinal absorption is apparently complete within 6 hours of ingestion. An inverse relationship was observed between the dose ingested and the relative absorption with therapeutic doses ranging from 0.5 to 1.5 g, suggesting the involvement of an active, saturable absorption process. Metformin is rapidly distributed following absorption and does not bind to plasma proteins. No metabolites or conjugates of metformin have been identified. The absence of liver metabolism clearly differentiates the pharmacokinetics of metformin from that of other biguanides, such as phenformin. Metformin undergoes renal excretion and has a mean plasma elimination half-life after oral administration of between 4.0 and 8.7 hours. This elimination is prolonged in patients with renal impairment and correlates with creatinine clearance. There are only scarce data on the relationship between plasma metformin concentrations and metabolic effects. Therapeutic levels may be 0.5 to 1.0 mg/L in the fasting state and 1 to 2 mg/L after a meal, but monitoring has little clinical value except when lactic acidosis is suspected or present. Indeed, when lactic acidosis occurs in metformin-treated patients, early determination of the metformin plasma concentration appears to be the best criterion for assessing the involvement of the drug in this acute condition. After confirmation of the diagnosis, treatment should rapidly involve forced diuresis or haemodialysis, both of which favour rapid elimination of the drug. Although serious, lactic acidosis due to metformin is rare and may be minimised by strict adherence to prescribing guidelines and contraindications, particularly the presence of renal failure. Finally, only very few drug interactions have been described with metformin in healthy volunteers. Plasma levels may be reduced by guar gum and alpha-glucosidase inhibitors and increased by cimetidine, but no data are yet available in the diabetic population. [less ▲]

Harpagophytum procumbens D.C. (Devil's Claw) secondary roots are used in Europe as a home remedy for lack of appetite, dyspeptic complaints, and in supportive therapy for degenerative disorders of the locomotor system. The main characteristic iridoid glucoside of the plant is harapagoside. An HPTLC method has been developed for the quantitative determination of harpagoside in the secondary roots and extracts of this plant. The mobile phase used is an optimized version of one described in the literature.It furnished the most homogenous spots for quantitative densitometric evaluation ( at lambda= 286 nm, the wavelenght of maximum absorption for harapgoside).The results have been compared with those obtained afetr visualization with sulfuric acid-vanillin reagent and those obtained using a previously published HPLC method; To check that separation was complete, the spectra of harpagoside obtained from Devil's Claw extracts before and after visualization were superimposed on thos of harpagoside standard.

Low temperatures have been used for many years to control populations of stored-product insects. The aim of aeration was primarily to cool down the grain and then to prevent its deterioration by reducing the number of insects. In Belgium, the mild winters enable insects to survive to the next season. In autumn, the progressive lowering of temperature has an acclimation effect on stored-product insects. The present study was undertaken to determine the survival at low temperatures of non cold-acclimated and laboratory- and field-cold-acclimated insects. We have chosen to work with the granary weevil Sitophilus granarius (L.) and the saw-toothed grain beetle Oryzaephilus surinamensis (L.). They are the most frequent stored-grain pests in Belgium. To compare the cold-hardiness of different laboratory cold-acclimated insects, S. granarius and O. surinamensis were placed at nine different cold-acclimation temperature regimes. Insects were kept at 5 degrees C for 2, 4 and 6 weeks or at -5 degrees C for 4, 7 and 14 days. To assess the field-cold-acclimation in autumn and in winter, insects were monthly taken from a bin and transferred to 5 degrees C for 6 weeks. S. granarius adults were more cold-hardy than O. surinamensis, but O. surinamensis adults compensated their cold-sensibility by a great ability to acclimate. S. granarius is able to survive the winter in Belgium because of its cold-hardiness while O. surinamensis survives because of its ability to acclimate to low temperatures. [less ▲]

Follicular dendritic cells (FDC) are unique non-lymphoid cells found only in lymph follicles. They play a part in the survival, proliferation and differentiation of B cells. To analyse the influence of FDC on B-lymphocyte proliferation, we isolated them from human tonsils on albumin gradients and treated them with mitomycin C to prevent the multiplication of lymphoid cells harboured in their cytoplasmic evaginations. FDC cultured for 12-16 h remained attached to the substrate; non-adherent cells were carefully eliminated by washing. Purified B cells cultured alone or with contaminant-cleared FDC were maintained for 2 days in the presence or absence of various stimulants, after which tritiated thymidine uptake by these cells was measured. In the absence of activators, FDC did not induce B-cell multiplication. B cells cultured in the presence of FDC exhibited increased 3H-TdR uptake when activated with anti-CD40 MoAb, anti-immunoglobulin MoAb or transferrin, but not when stimulated with Staphylococcus aureus strain Cowan I (SAC) at a given concentration. In the latter case, B-cell proliferation clearly decreased. In control cocultures where mitomycin-C-treated non-adherent cells were used instead of FDC in the presence of the different stimulants, no increase in B-cell proliferation was observed. The results suggest that, inside the germinal centres, FDC modulation of B-cell proliferation depends on the activation state of the B cells and on the stimulant encountered. [less ▲]

Because of the common failure of the various medical procedures used for the treatment of morbid obesity, surgeons have searched alternatives among which gastroplasty appears to offer now the best efficacy/safety ratio. Such approach has become more and more popular in our country, but success is almost highly variable from patient to patient. A careful medical assessment is necessary before performing gastroplasty. It mainly aims at choosing the appropriate indications (failure of previous well-applied medical therapy, exclusion of any hormonal cause of obesity, presence of complications due to weight excess, ...) and at excluding cardiovascular (unstable coronaropathy, carotid stenosis, ...), digestive (recurrent oesophagitis, ...) or psychiatric contra-indications. Such medical assessment before gastroplasty should allow to increase the success rate and to reduce the incidence of complications after the surgical procedure. [less ▲]

The purpose of this study was to characterize circulating growth hormone-binding proteins (GHBP) and prolactin-binding proteins (PRLBP) in cattle blood plasma. In particular, the 24-hr profile of these molecules was investigated. The preincubation of bull plasma with iodinated bovine growth hormone (bGH) or bovine prolactin (bPRL), followed by gel filtration chromatography (Superdex 200; 1.6 x 60 cm column), resulted in the formation of essentially two complexes. The majority of [125I]bPRL eluted with the first one (M(r) approximately 600 kDa), whereas [125I]bGH mainly appeared in the second one (M(r) approximately 70 kDa). The fractions corresponding to these two peaks were analyzed by western ligand blotting (WLB), under reducing conditions. WLB revealed, respectively, 190-, 56-, 52-, and 28-kDa bands for the first peak and only 52- and 28-kDa bands for the second one. The nature of the 600-kDa peak is at present undetermined, but the 70-kDa one was previously identified as high-affinity GHBP. Displacement studies demonstrated that bGH and bPRL were both able to bind to this GHBP, because the bGH- and bPRL-binding activities of this protein could be saturated by an excess of either of these two hormones. This was indirectly confirmed by the close correlation (r = 0.615; P = 0.0001; n = 155) observed between plasma bGH- and bPRL-binding activities, because this correlation could suggest that both ligands are bound to the same proteins. The temporal concentrations of plasma GHBP were measured in samples collected at 20-min intervals for 24 hr from 8 young bulls. The evaluation of GHBP was realized by WLB, followed by densitometric analysis. Some fluctuations were observed, but these were not correlated with bGH release, even with a +/- 2-hr lag period. In summary, we found that bovine high-affinity GHBP binds not only bGH, but also bPRL. A second type of protein, of higher molecular weight, also binds these two hormones, but further investigations are needed to determine its nature. Finally, GHBP concentrations in cattle blood plasma apparently show fluctuations over a 24-hr period, but no correlation was found between these fluctuations and plasma growth hormone concentrations.

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 ▲]

Two experiments were carried out on sheep to measure the effects of some factors of the mobile nylon bag (MNB) technique on the intestinal digestibility (DgI) of rumen undegraded N of meat and bone meal (MBM), soybean meal (SBM) and wheat bran (WB). The pore size of the nylon cloth (IO and 42.5 pm) influenced (P < 0.05) DgI of SBM and MBM N irrespective of the site of recovery of the bags (ileum and faeces) and the incubation time of concentrate feeds in the rumen (0, 2, 4, 8, 16 and 24 h). The faecal recovery of the bags increased (P < 0.05) DgI of SBM N in comparison with ileal recovery. The opposite was found with WB incubated 4, 8, 16 and 24 h in the rumen. DgI of MBM N was not influenced by site of bag recovery (P > 0.05). Increasing incubation times in the rumen decreased (P < 0.05) DgI of undegraded feed N. The total tract digestibility (rumen plus intestines) was independent of incubation time in the rumen for MBM and SBM, excepted for SBM incubated 4 or 8 h in the rumen when bags were collected in the ileum. Previous ruminal incubation of WB for 4, 8, 16 and 24 h increased (P < 0.05) the amount of N digested in the total tract in comparison with unincubated WB and WB incubated for only 2 h. In the second experiment, residues obtained from the incubation of the feeds in the rumen (0, 2, 4, 8, 16, 24 and 48 h) were mixed in different proportions in order to obtain the true fraction of the undegraded feed in the rumen. This method was based on the DM degradability of the concentrate feeds and the outflow rate constant of feeds from the rumen, supposed equal to 6%h-‘. Bags containing feeds mixed according to this method were incubated in a solution of pepsin-HCl for 0, 1, 2 and 3 h to simulate abomasal digestion and the DgI of N was measured afterwards with the MNB technique. Increasing action of pepsin led to higher digestibilities of N at this stage (P < 0.05) but decreased the digestibility of N in the intestines excepted for MBM incubated in pepsin-HCl for 3 h and in any case for SBM. However, the omission of the incubation in pepsin had little influence on the amount of N postruminally digested. [less ▲]

The ganglionic cell type in which varicellazoster virus (VZV) is latent in humans was analyzed by using antibodies raised against in vitro-expressed VZV open reading frame 63 protein, VZV open reading frame 63 protein was detected exclusively in the cytoplasm of neurons of latently infected human trigeminal and thoracic ganglia. This is, to our knowledge, the first identification of a herpesvirus protein expressed during latency in the human nervous system. [less ▲]

The glycoproteins of bovine herpesvirus 1 (BHV-1) play important roles in the interactions between virions and target cells. A 108 kDa glycoprotein, designated gII or gp 108, has been identified by two different panels of monoclonal antibodies. The gII- and gp 108-specific monoclonal antibodies were shown to react with the same protein, which was identified by N-terminal sequencing as the homologue of herpes simplex virus type 1 (HSV-1) gH. When BHV-1 gH was purified by immunoadsorbent chromatography, gL was co-purified. The gH-gL complex induced the production of antibodies that neutralized virus infectivity and inhibited virus penetration. Affinity-purified gH-gL did prevent penetration, but not attachment of BHV-1, which suggests that the gH-gL complex is essential for penetration of BHV-1 into susceptible cells. [less ▲]

We investigated the effect of peptide G, a synthetic peptide derived from the sequence of the 37-kDa laminin receptor precursor, on the interaction of laminin in two tumor cell lines one of which produces laminin and one of which does not. Addition of peptide G to the culture medium induced a significant increase in the amount of endogenous laminin detectable on the cell membrane of both cell lines. Moreover, pretreatment of exogenous laminin with peptide G dramatically increased laminin binding on both cell lines. Kinetics analysis of membrane-bound labeled laminin revealed a 3-fold decrease in the kd of peptide G-treated laminin compared with untreated or unrelated or scrambled peptide-treated laminin. Moreover, the affinity constant of peptide G-treated laminin increased 2-fold, with a doubling of the number of laminin binding sites, as determined by Scatchard analysis. Expression of the VLA6 integrin receptor on the cell membrane increased after incubation with peptide G-treated laminin. However, the lower binding inhibition of peptide G-treated laminin after anti-VLA6 antibody or cation chelation treatment indicates that membrane molecules in addition to integrin receptors are involved in the recognition of peptide G-modified laminin. These "new" laminin-binding proteins also mediated cell adhesion to laminin, the first step in tumor invasion. Together, the data suggest that peptide G increases and stabilizes laminin binding on tumor cells, involving surface receptors that normally do not take part in this interaction. This might explain the abundant clinical and experimental data suggesting a key role for the 67-kDa laminin receptor in the interaction between cancer cells and the basement membrane glycoprotein laminin during tumor invasion and metastasis.
