Un constat semble s'impoesr à tout observateur des sociétés contemporaines : les jeunes générations, plus sensibles aux changements qui affectent les différentes sphères de la vie sociale, expérimenteraient de nouveaux rapports aux institutions traditionnelles, tiraillés entre l'attachement et le détachement aux repères qui ont valu pour ceux qui les ont précédés. Mais on peut considérer que la jeunesse n'apparaît en tant qu'objet singulier qu'à travers une grille de lecture "institutionnalisée", largement portée par les intervenants sociaux et les acteurs politiques, et où s'affirme avant tout le dessein d'un encadrement, voire d'une réappropriation, des pratiques juvéniles. Il n'y aurait donc pas, dans les discours sur la jeunesse, de regard désintéressé, susceptible de considérer ses pratiques dans leur spécificité. Une approche sociologique de la jeunesse ne peut dès lors faire l'économie d'une réflexion critique sur les grilles de lecture communément admises et utilisées pour définir la condition contemporaine de la jeunesse.

BACKGROUND: Donor lymphocyte infusion (DLI) is currently standard therapy for relapse of malignancies after allogeneic BMT. Several observations suggest that both normal and leukemic progenitor cells of host origin constitute effective target cells for donor-derived lymphocytes. To prevent relapse of sickle cell disease (SCD), a child with evidence of decreasing mixed chimerism received DLIs 8 months after allogeneic BMT for SCD. CASE REPORT: A 4-year-old child who was homozygous for SCD underwent a transplantation of bone marrow from his fully HLA-matched sister. Routine detection of sex chromosomes in bone marrow cells evidenced decreasing mixed chimerism, which heralded a probably imminent recurrence of the disease. The patient received two DLIs in graded incremental doses on Days 234 and 267. One month later, he developed grade 2 acute GVHD that responded well to corticosteroids and cyclosporine. RESULTS: DLI resulted in complete donor chimerism within 2 months of the second infusion. Now, 2 years after the second DLI, the patient is in excellent condition, with normal Hb and excellent growth and development. CONCLUSION: This is the first report of successful use of DLI in a patient with probable imminent SCD recurrence after allogeneic BMT. It shows that DLI can displace residual host HPCs in case of recurrence of nonmalignant disease after allogeneic BMT. [less ▲]

The respective contributions of pituitary and placental GH to circulating IGF-I in pregnant women have not been well established. We measured the serum concentrations of placental growth hormone (PGH) and IGF-I in a woman with pit-1 deficiency before, during and after pregnancy, resulting in the birth of a healthy child (not pit-1 deficient). Both PGH and IGF-I concentrations were below the assay detection limit before and after pregnancy. During pregnancy, PGH and IGF-I levels increased steadily; the concentrations of PGH and IGF-I in late pregnancy were comparable with levels previously measured in normal pregnancies. PGH and IGF-I concentrations were strongly correlated throughout pregnancy (r = 0.90; P = 0.002). PGH was undetectable in cord serum, whilst the IGF-I concentration was within the normal range. The findings of this case study corroborate the notion that PGH is the prime regulator of maternal serum IGF-I during pregnancy. [less ▲]

OBJECTIVE: To isolate new cDNAs corresponding to genes whose expression is increased during castration-induced rat prostate apoptosis. MATERIALS AND METHODS: Differential display of mRNAs from 3-day castrated and normal rat ventral prostates was used to identify differentially expressed clones. Northern blots were hybridized to confirm the positive regulation of the candidates and to follow the change in their expression in the involuting rat prostate, and in thymocytes of dexamethazone-treated rats. RESULTS: Five cDNAs were cloned: one encoding ribosomal protein L7, one coding for the insulin-like growth factor binding protein-3 (IGFBP-3), and three whose products are unknown. After castration, all five genes had expression kinetics that closely paralleled the proportion of prostatic epithelial cells undergoing apoptosis. The gene encoding L7 and two of the unknown genes were also upregulated in glucocorticoid-induced programmed death in thymocytes. In addition to the IGFBP-3 gene, those coding for proteins IGFBP-4, -5 and -6 were also overexpressed in the involuting prostate of androgen-deprived rats. CONCLUSION: Five new genes were identified that are up-regulated during castration-induced rat prostate apoptosis, three of which are potentially involved in the common intracellular pathway leading to programmed cell death.

As a result of a world-wide intensive research activity, a new design concept for structural moment resistant joints has been suggested and implemented in design codes. In the present paper, its background is first briefly described and the main contributions to its development are presented. As a matter of fact, because of the high number of past and ongoing researches, reports and papers devoted to this topic, an exhaustive list of all these works could not be established in a limited number of pages. The possibilities of extension of the new design concepts, which have been first developed for steel beam-to-column joints under static loading, are particularly pointed out. This aspect appears quite important as in the near future it should provide designers with a unified design approach for structural joints whatever their loading, their configurations and the nature of their constitutive material(s).

Applying the EPIK parametric method, a vulnerability assessment has been made for a small karstic groundwater system in southern Belgium. The aquifer is a karstified limestone of Devonian age. A map of intrinsic vulnerability of the aquifer and of the local water-supply system shows three vulnerability areas. A parameter-balance study and a sensitivity analysis were performed to evaluate the influence of single parameters on aquifer-vulnerability assessment using the EPIK method. This approach provides a methodology for the evaluation of vulnerability mapping and for more reliable interpretation of vulnerability indices for karst groundwater resources. [less ▲]

Tumor angiogenesis is one of the most important fields of cancer research. It is important to identify the putative targets for antiangiogenic strategies. To date, a number of angiogenic agents have been identified: bFGF, the different VEGF isoforms, integrins, proteases (matrix metalloproteases and serine proteases),... Furthermore, several physiological anti-angiogenic agents have been isolated such as endostatin, angiostatin, 16 K prolactin,.... The recent development of mice deficient for one gene involved during angiogenesis gives a new insight into the molecular mechanisms regulating this process. It leads to the identification of plasminogen activator inhibitor-1 or PAI-1 as a new target for tumor treatment. Although, PAI-1 is very attractive as a target for new therapeutic strategies, a better understanding of its mechanism of action is needed urgently. [less ▲]

Vitamin A deficiency produces anemia and altered iron status. In this study with rats we tested two hypotheses regarding vitamin A deficiency: (1) that it impairs erythropoiesis, leading to an increased red cell turnover, and (2) that it inhibits the glycosylation of transferrin. Erythropoietic activity was assessed indirectly by determining the myeloid:erythroid ratio in bone marrow smears, the number of erythroid colonies in the red pulp of spleen, the blood reticulocyte index, and zinc protoporphyrin and plasma transferrin receptor concentrations. Transferrin glycosylation was assessed by measuring the sialic acid content of transferrin. The effects of vitamin A deficiency were compared with those of iron deficiency. Iron deficiency produced anemia and low iron levels in organs. Vitamin A deficiency produced low levels of plasma and hepatic retinol, and it induced decreased plasma total iron-binding capacity and raised iron levels in tibia and spleen. Short- but not long-term iron deficiency reduced the number of erythroid colonies in spleen; vitamin A deficiency had no influence. Neither iron nor vitamin A deficiency influenced the myeloid:erythroid ratio in bone marrow smears and the blood reticulocyte production. Plasma transferrin receptor and erythrocyte zinc protoporphyrin concentrations were not affected by vitamin A deficiency but increased with iron deficiency. Vitamin A deficiency did not stimulate erythrocyte breakdown, as indicated by unaltered plasma lactate dehydrogenase activity and reduced plasma total bilirubin levels. Both vitamin A and iron deficiencies raised the proportion of multiple sialylated transferrins in plasma. Thus, we have not found evidence that vitamin A deficiency affects erythropoiesis and erythrocyte turnover. The iron accumulation in spleen and bone marrow may be related to reduced iron transport due to inhibition of transferrin synthesis rather than inhibition of transferrin sialylation. [less ▲]

Volume tables have been constructed for European larch (Larix decidua Mill.), Japanese larch (Larix kaempferi (Lamb.) Carr.) and hybrid larch (Larix X eurolepis Henry) trees in the Ardenne (southern part of Belgium), which is a natural region located at elevations ranging from 340 to 550 m on mainly siliceous rocks. The application of the proposed tables is only for trees whose diameters (d.b.h.) are less than 22 cm over bark at 1.3 m above ground level. They are particularly useful for estimating total tree volume of trees (excluding branches) of early thinnings and volume increment of small-sized trees in genetic improvement experiments. The volume equations are based on data collected over a wide range of site conditions. In these regional volume tables, the volumes (total volume of the stem and volume to an upper diameter limit of 7 cm) are correlated with both d.b.h. and total height. [less ▲]

The noninvasive assessment of tumor hypoxia in vivo is under active investigation because hypoxia has been shown to be an important prognostic factor for therapy resistance. Various nuclear medicine imaging modalities are being used, including PET imaging of 18F-containing compounds. In this study, we report the development of 18F-labeled EF1 for noninvasive imaging of hypoxia. EF1 is a 3-monofluoro analog of the well-characterized hypoxia marker EF5, 2(2-nitro-1H-imidazol-1-yl)-N-(2,2,3,3,3-pentafluoropropyl)acetami de, which has been used to detect hypoxia in tumor and nontumor systems using immunohistochemical methods. METHODS: We have studied 2 rat tumor types: the hypoxic Morris 7777 (Q7) hepatoma and the oxic 9LF glioma tumor, each grown in subcutaneous sites. PET studies were performed using a pharmacological dose of nonradioactive carrier in addition to [18F]EF1 to optimize and assess drug biodistribution. After PET imaging of the tumor-bearing rats, tissues were obtained for gamma-counting of the 18F in various tissues and immunohistochemical detection of intracellular drug adducts in tumors. In one pair of tumors, Eppendorf needle electrode studies were performed. RESULTS: [18F]EF1 was excreted dominantly through the urinary tract. The tumor-to-muscle (T/M) ratio of [18F]EF1 in the Q7 tumors was 2.7 and 2.4 based on PET studies and 2.1, 2.5, and 3.0 based on gamma-counting of the tissues (n = 3). In contrast, the T/M ratio of [18F]EF1 in the 9LF glioma tumor was 0.8 and 0.5 based on PET studies and 1.0, 1.2, and 1.4 based on gamma-counting of the tissues (n = 3). Immunohistochemical analysis of drug adducts for the two tumor types agreed with the radioactivity analysis. In the Q7 tumor, substantial heterogeneous binding was observed throughout the tumor, whereas in the 9LF tumor minimal binding was found. CONCLUSION: [18F]EF1 is an excellent radiotracer for noninvasive imaging of tumor hypoxia. [less ▲]

OBJECTIVE: To assess in vivo blood oxygen binding in double-muscled calves and dairy calves with conventional muscle conformation. ANIMALS: 58 dairy and 48 double-muscled calves. PROCEDURE: Calves were classified as neonatal (24 hours old) or older calves (2 to 26 days old). Venous and arterial blood samples were collected, and hemoglobin concentration, pH, PCO2, and PO2 were determined. Blood oxygen equilibrium curves (OEC) under standard conditions were constructed, and the oxygen exchange fraction (OEF) and the amount of oxygen released at the tissue level by 100 ml of blood (OEF Vol%) were calculated. RESULTS: In each breed, partial pressure of oxygen at 50% saturation of hemoglobin (P50) under standard conditions was significantly higher in older than in neonatal calves, indicating a right shift in OEC with age. Venous P50 was significantly lower in neonatal double-muscled calves than in neonatal dairy calves, but arterial and venous P50 were significantly higher in older double-muscled calves than in older dairy calves. In double-muscled, but not in dairy, calves, OEF was significantly higher in older than in neonatal calves. In neonatal calves, OEF Vol% was not significantly different between breeds, but OEF Vol% was significantly higher in older double-muscled calves than in older dairy calves. CONCLUSIONS AND CLINICAL RELEVANCE: The lower OEF in neonatal double-muscled calves, compared with dairy calves, could contribute to the higher sensitivity of double-muscled calves to hypoxia. Blood oxygen affinity decreased with age, but OEF and OEF Vol% were unchanged with age in dairy calves, whereas they increased with age in double-muscled calves [less ▲]

Bovine leukemia virus (BLV) Tax protein, a transcriptional activator of viral expression, is essential for viral replication in vivo. Tax is believed to be involved in leukemogenesis because of its second function, immortalization of primary cells in vitro. These activities of Tax can be dissociated on the basis of point mutations within specific regions of the protein. For example, mutation of the phosphorylation sites at serines 106 and 293 abrogates immortalization potential in vitro but maintains transcriptional activity. This type of mutant is thus particularly useful for unraveling the role of Tax immortalization activity during leukemogenesis independently of viral replication. In this report, we describe the biological properties of BLV recombinant proviruses mutated in the Tax phosphorylation sites (BLVTax106+293). Titration of the proviral loads by semiquantitative PCR revealed that the BLV mutants propagated at wild-type levels in vivo. Furthermore, two animals (sheep 480 and 296) infected with BLVTax106+293 developed leukemia or lymphosarcoma after 16 and 36 months, respectively. These periods of time are within the normal range of latencies preceding the onset of pathogenesis induced by wild-type viruses. The phenotype of the mutant-infected cells was characteristic of a B lymphocyte (immunoglobulin M positive) expressing CD11b and CD5 (except at the final stage for the latter marker), a pattern that is typical of wild-type virus-infected target cells. Interestingly, the transformed B lymphocytes from sheep 480 also coexpressed the CD8 marker, a phenotype rarely observed in tumor biopsies from chronic lymphocytic leukemia patients. Finally, direct sequencing of the tax gene demonstrated that the leukemic cells did not harbor revertant proviruses. We conclude that viruses expressing a Tax mutant unable to transform primary cells in culture are still pathogenic in the sheep animal model. Our data thus provide a clear example of the discordant conclusions that can be drawn from in vitro immortalization assays and in vivo experiments. These observations could be of interest for other systems, such as the related human T-cell leukemia virus type 1, which currently lack animal models allowing the study of the leukemogenic process.

Various epidemiological studies suggested that individuals with high intake of antioxidant vitamins (E, A and C) have a better cardiovascular prognosis than subjects with relative deficiencies in such vitamins. However, placebo-controlled randomized clinical trials did not demonstrate that a specific supplementation in either alpha-tocopherol (vitamin E) or beta-carotene (vitamin A) allows to reduce the incidence of major cardiovascular events, in the general population or even in various subgroups at high risk, and there is no such controlled trials with vitamin C alone. Some studies suggested that combined supplements of several antioxidant vitamins might be more efficacious, and these observations led to initiate several large controlled studies. Thus, until now, there is no convincing arguments in the literature in favour of artificial supplements of antioxidant vitamins. It seems preferable to encourage a well-balanced healthy diet while awaiting the results of the large prospective ongoing trials with combined supplementation. [less ▲]

The osmotic behavior of bovine blastocysts produced in vitro was filmed during exposure to and dilution of cryoprotectant solutions used for vitrification. The relationship between the changes in the diameter of embryos and their subsequent survival was assessed. Embryos collected on Day 6 and Day 7 postinsemination were exposed to 10% glycerol (GLY) for 5 min, 10% GLY + 20% ethylene glycol (EG) for 5 min, and 25% Gly + 25% EG for 30 s, before dilution in 0.85 M galactose and finally in embryo transfer freezing medium (ETF). Embryos that had a higher probability of survival behaved as perfect osmometers, shrinking, reexpanding, or swelling according to an identical pattern, whereas embryos that deviated from this standard usually did not survive. The initial embryo diameter, duration of shrinkage and expansion in 10% glycerol, duration of reexpansion in ETF, and final embryo diameter were clearly predictive of the ability to hatch after culture in vitro. On a given day postinsemination, larger blastocysts were more likely than smaller blastocysts to survive and hatch after exposure to cryoprotectants with or without vitrification. [less ▲]

This paper aims to present the nutritional requirements of cats suffering from chronic renal failure, the most common condition in renal pathology. Indeed, the concept consisting in a reduced protein content diet is a little out of date. Renal anatomy and function are reviewed as well as the main renal pathologies. Incidence, symptoms, diagnosis and overall dietary management are developed. The different nutrients to be taken into consideration are discussed, according to the evolution's state of the disease. Finally, a comparison between different pet foods for chronic renal failure shows a largely variable composition and should help the practitioner to make the best choice for its patient.

We have cloned a novel complementary DNA whose expression was decreased in rat Sertoli cell cultures after treatment with FSH. This complementary DNA encodes a protein of 570 amino acids and shares 92% homology with the human MAGE-D protein. In contrast to other MAGE genes (A, B, or C), we have shown that MAGE-D expression was ubiquitous in healthy rat tissues. In the seminiferous tubules, the MAGE-D was expressed in Sertoli cells but not in germ cells as demonstrated by RT-PCR and in situ hybridization, whereas for the other MAGE genes, expression has been shown to be restricted to germ cells. Interestingly, MAGE-D was also detected for the first time in the female gonad by Northern blotting. In MLTC-1 cells (mouse Leydig tumor cell line-1), LH and PRL stimulated MAGE-D expression. Using hypophysectomized rats, it was confirmed that FSH decreased MAGE-D expression, whereas LH and PRL increased MAGE-D messenger RNA level in the whole testis most probably through a direct action on Leydig cells. As MAGE-D is present in both the seminiferous compartment and interstitium and hormonally regulated in each, it is possible that it has specific functions in each compartment during the development and the maintenance of the testis.

Arterial blood gases, acid-base balance and respiratory function tests using impulse oscillometry (IOS) were performed on 40 clinically healthy newborn calves during the first 24 hours of life to evaluate their respiratory adaptation to extrauterine life. Gas exchange efficiency of the lung was significantly improved with time and was accompanied by the correction of the mixed acidosis observed at birth and by significant changes in respiratory mechanics. Major changes were detected within the first 6 hours. The significant decrease in resistance (R) and the increase in reactance (X) with time, demonstrate the improvement in respiratory mechanics of both upper and lower airways, and reflect the increase in lung volume, the improved lung tissue elasticity and/or distribution of the ventilation. Respiratory mechanical, arterial blood gases and acid-base balance data provided in this study describe a successful respiratory adaptation to extrauterine life in healthy newborn calves. [less ▲]

Onuxodon fowleri and Encheliophis dubius are two Carapidae species that live in bivalve hosts and, their diet is made of the same type of prey. The aim of this study is to compare their cephalic morphology to see whether 1) the head anatomy of both species is related to the constraints of their way of life, and 2) there are difference between these species and commensal carapids that shelter in other invertebrates. The components of their skeletons and muscles are similar, but differ in size and are arranged differently. In O. fowleri, the buccal cavity is smaller than in E. dubius, the jaws (bearing very large anterior teeth) are larger, the quadrato-mandibular joint lies further to the rear, the fibres of muscle bundles A3a, A2a and A2b are more vertical and insert higher on the neurocranium. The buccal system of O. fowleri appears better suited for ingesting food by biting and grasping. That of E. dubius seems better adapted to a feeding mechanism where sucking would have a more important role. The E. dubius head morphology is more similar to the cephalic anatomy of non-bivalve commensal species than to O. fowleri features. Diet constraints may have greater influence than the different host constraints on the head construction. A simulated backward rotation of the posterior part of the E. dubius suspensorium around the posterior joint between the hyomandibular and the neurocranium brings the jaws and the cheeks to coincide with those of O. fowleri. This model could be indicative of how structure modifications and their influences on annex pieces could in part have a role in the biodiversity. [less ▲]

MRI guided percutaneous abdominal biopsy was evaluated in an animal model, using a closed magnet and different types of needles. Thirty-six single pass biopsies were performed in 6 piglets with 6 types of MR compatible needles. Virtual targets of a diameter of 2 cm were drawn on the images of the right and left lobe of the liver and the upper and lower poles of both kidneys. FMPSPGR sequences were applied during an apnea of 19 to 23 seconds in axial, sagittal, coronal or axial oblique planes using a closed 1.0 T magnet and the body coil. Piglets were autopsied 1 hour after the procedure. Mean duration of the procedure was 16.9 (11-37) minutes; mean number of acquisitions per procedure was 5.9 (3-12); mean number of redirections of the needle was 0.6 (0-4). Pathological samples from the liver and kidneys of good quality were obtained in 22/36 (72.2%) cases. A subcapsular hematoma was observed in 18/24 (75.0%) cases of renal biopsies and in 1/12 (8.3%) of hepatic biopsies. No statistically significant correlation could be established between duration of the procedure and site of biopsy and between the type of biopsy needle and complication (p = 0.18 to 0.85). In conclusion, MRI guided percutaneous needle biopsy in the abdomen is a reliable technique in piglets using a closed magnet. [less ▲]

It is now widely established that systematic intraoperative location and diligent dissection of the recurrent inferior laryngeal nerve during thyroidectomy are the keystones to assure its anatomic and functional preservation. The possibility of abnormal routes, like a non-recurrent cervical course of the inferior laryngeal nerve is an additional major argument for its systematic identification to avoid surgical damage. In 2517 cervicotomies performed between 1992 and 1997 for at least right thyroid lobe excision or parathyroid glands exploration, 20 cases of non recurrent laryngeal nerve were identified (0.79%). The embryological nature of such a nervous anatomical variation results originally from a vascular disorder, named arteria lusoria in which the fourth right aortic arch is abnormally absorbed, being therefore unable to drag the right recurrent laryngeal nerve down when the heart descends and the neck elongates during embryonic development. The surgeon must be aware of the possibility of a non recurrent laryngeal nerve, which arises directly from the cervical vagus and therefore represents a severe potential pitfall during thyroidectomy. Given the absence of reliable clinical symptoms and signs or investigations indicating preoperatively the possibility of a non recurrent nerve, guidelines are given to prevent intraoperatively this major surgical risk.

The three-step technique was used to determine the requirements of total amino acids (TAA) and the first-limiting amino acid (AA) in growing double- muscled Belgian Blue bulls (BBb). In Exp. 1, three double-muscled BBb weighing initially 306 ± 28 kg received a basal diet consisting of 30% meadow hay and 70% concentrate that was poor in digestible protein but had adequate NE because of continuous infusion of dextrose into the duodenum. The intestinal apparent digestibility of essential AA (EAA) was defined according to their duodenal and ileal flows. It averaged 72% but varied between 60% for Met and 79% for Arg. In Exp. 2, five double-muscled BBb (334 ± 22 kg) received the same diet supplemented with duodenal infusions of dextrose and four doses of Na-caseinate (28, 56, 84, and 112% of intestinal digestible dietary AA) in a 4 × 4 Latin square design with one additional animal. Nitrogen retention for the basal diet alone and the four increasing supplements of Na-caseinate reached 49, 61, 70, 80, and 86 g/d, respectively. Nitrogen utilization improved from 34.3% without Na-caseinate supplementation to a maximum of 40.6%, with the third dose supplying 788 g/d of apparently digestible AA. Based on patterns of plasma concentrations, Met, Phe, and Arg were probably the limiting AA when animals optimized N utilization. In Exp. 3, six double-muscled BBb (315 ± 25 kg) fed the basal diet received duodenal infusions of dextrose and AA, equivalent to the third dose in Exp. 2, except for digestible Met (9.3, 14.4, 18.4, 22.4, 26.4, and 30.4 g/d) in a 6 × 6 Latin square design. The Met requirement was close to 26.4 g/d on the basis of N retention. [less ▲]

Norway spruce (Picea abies (L.) Karst.) is the first forest species devoted to production in the Wallonian region. Many private and public foresters have to face management problems for these stands : rotation length, definition of thinning type, harvesting scheduling, future income and profitability estimation, ... The management model presented in this article can give some answers to these questions. It is made of two components : on one hand, a growth model predicts stand growth in connection with site index and silvicultural parameters, and, on the other hand several modules compute silvicultural indicators (stability index, mortality rate, assortments, ...) and financial indicators (prediction of future incomes and profitability). The management model allows to test and compare in a flexible way different scenarios applicable to stands described by their initial stage (number of stems and basal area per hectare, dominant height). These tools are integrated in a spreadsheet application using Excel TM, which makes it very easy to use by the forest manager who wants to base his managment on objective criteria. [less ▲]

Five batches of a total of 180 weaned pigs were reared successively in an experimental room on 30 cm deep litter without cleaning between the batches. The litter was a mixture of sawdust from coniferous and beech trees. Water was added to the Litter every 10 days to lower the dust concentration in the room. The total amounts of sawdust and water used were respectively 21.3 kg per pig and 10.21 per pig. The mean temperature of the litter at 20 cm depth recorded during each of the 5 periods varied from 32.5 degrees C to 41.8 degrees C. The average liveweight of the pigs at the beginning and at the end of the post-weaning period was respectively 7.9 +/- 1.2 kg and 24.5 +/- 4.2 kg. The average daily gain was 392 +/- 87 g. The temperature and the relative humidity of the air inside and outside the experimental room and the ventilation rate were continuously recorded in order to calculate the water vapour emission for each batch. The amount of water vapour produced was significantly correlated to the water consumption of the pigs and reached an average of 1 732 g per pig per day. This amount is 36% greater than the reference used for pigs on slatted floors. This value may be used as a reference to calculate the minimum ventilation rate for piggeries with pigs on sawdust deep litters. The amount of compost produced was 19.9 kg per pig with a dry matter content of 44.7%. The amount of nitrogen in the compost was 231 g per pig which is about 50% lower than the reference used for the slurry. The volatile nitrogen emissions are thus much higher from composts than from slurries [less ▲]

The administration of cyclosporin A (CyA) after autologous haematopoietic stem cell transplantation (HSCT) induces a systemic autoimmune syndrome mimicking graft-vs.-host disease (GVHD). This syndrome, termed autologous GVHD has notable anti-tumour activity in animal studies. We intended to induce autologous GVHD with CyA in patients undergoing an autologous HSCT. We prospectively studied 118 patients with miscellaneous malignancies undergoing an autologous HSCT with low-dose CyA to characterize the clinical syndrome, its frequency and clinical course, and to determine the factors affecting its incidence. Patients received CyA from d -1 through to d 28, first starting at 2 mg/kg intravenously and then orally as soon as feasible. The dose was adjusted to achieve pre-dose blood levels around 100 ng/ml. A skin biopsy was performed when a skin rash was observed. Thirty-three percent of the patients developed clinical GVHD: clinical stage 1 in 21 patients, stage 2 in seven patients, and stage 3 in three patients. Although total body irradiation (TBI) or high-dose cyclophosphamide were previously thought to be needed, autologous GVHD occurred in five out of 12 patients (42%) after a preparative regimen with high-dose melphalan alone. Autologous GVHD was significantly more frequent in patients older than 33 years, in patients who had received high doses of granulocyte-macrophage colony forming units (CFU-GM) and in those with a diagnosis of myeloid malignancy, compared with those with lymphoid malignancies or solid tumours. A significant negative association was also found with HLA-DR6. In lymphoma patients, GVHD occurred more frequently in advanced disease than in first or second complete remission (CR1-2) patients. All other factors studied were not predictive for GVHD. In conclusion, CyA-induced GVHD is reproducibly and safely induced with doses of CyA adapted to achieve blood levels around 100 ng/ml. In retrospective analysis, there was no survival advantage for patients with GVHD. Phase III trials with this approach are needed to evaluate its anti-tumoral effect. [less ▲]

Diabetes mellitus is a frequent metabolic disease characterised by a complex and inconstant phenotypic expression that complicates the classification of patients and sometimes delays their optimal management. In that slowly progressive disease leading to severe and irreversible complications, the use of early and specific genetic, immunological and/or metabolic markers may help in the classification of diabetic patients and in the orientation of therapeutic strategies; furthermore, it is also an essential aid in the early screening of subjects at risk of developing the disease. The assessment of classical immunological markers, such as islet cell antibodies (ICA) or anti-insulin antibodies (IAA) has been recently completed by the screening of new promising markers such as GAD- and IA2-antibodies. The presence of these markers confirms the autoimmune component of the disease and thus supports the diagnosis of type 1 diabetes, even if clinical symptoms are absent or inconsistent. In addition, it represents a strong argument in favour of the initiation of specific immunological therapies to preserve B-cell number and function. [less ▲]

The objective of the present study was to analyze the pattern of oral contraceptive (OC) use in teenagers and to examine the relationship between OC use and other cardiovascular risk factors. The study was conducted in 24 Belgian secondary schools. Most students (1526 adolecents aged 12-17 years) agreed to participate (participation rate: 83.6%). Smoking, physical activity habits, menarche, and OC use were assessed by a self-administered questionnaire. Total cholesterol level, blood pressure and anthropometric measurements were also measured. Fourteen per cent of mature girls (14%, n=92) were OC users. Two-thirds of them (66.3%, n=61) were taking OC which contained either gestodene or desogestrel. Blood pressure and BMI were similar for OC users and non-users. Total cholesterol level was significantly higher in OC users than in non-users (191 mg/dL versus 172 mg/dL). Logistic regression model confirmed the significant influence of OC use on total cholesterol level (OR=3.08). OC users were also often smokers (39% versus 20% for non-users). In conclusion, the present study has found significant relationship between OC use and cardiovascular risk factors i.e., high total cholesterol and smoking. The first implication is a need for further research on lipoprotein profile in young OC users. Secondly, the combined use of OC and smoking in teenagers calls for preventive actions. [less ▲]

To assess the contraceptive reliability, cycle control and tolerability of a new monophasic oral contraceptive containing 30 g ethinylestradiol plus 3 mg drospirenone (Yasmin, Schering AG, Berlin, Germany), it was compared with an established oral contraceptive containing 30 g ethinylestradiol plus 150 g desogestrel (Marvelon, NV Organon, Oss, The Netherlands). METHODS: A randomized, open-label, 13-cycle study was performed at 80 European centers. Contraceptive reliability, cycle control, blood pressure, body weight, the incidence of adverse events and skin condition were assessed during 13 cycles of oral contraceptive use, and at follow-up. Subjects recorded body weight on three consecutive days pretreatment and weekly thereafter. RESULTS: Of 2069 women who started the study and received the trial preparations in a ratio of 4:1 (ethinylestradiol/drospirenone, n = 1657; ethinylestradiol/desogestrel, n = 412), 1615 completed the 13 cycles plus follow-up, providing data for over 23,000 evaluable cycles. Eleven pregnancies occurred during treatment, only one of which (in the ethinylestradiol/drospirenone group) could not be ascribed to user failure or interaction with other factors. Both preparations provided effective contraception and cycle control. Pre-existing acne and seborrhea were improved and blood pressure was essentially unchanged. The two treatments differed in their effect on body weight, the difference being statistically significant. In the ethinylestradiol/drospirenone group, there was a distinct decrease over the whole treatment phase, while a subtle and less distinct decrease was documented in the ethinylestradiol/desogestrel group. CONCLUSIONS: The combination of 30 g ethinylestradiol/3 mg drospirenone provides effective oral contraception, excellent cycle control, good tolerability and a level of weight loss that may have a significant beneficial effect on compliance in women with a tendency to weight gain due to water retention.

The local magnetic moment of Fe in Dy-Fe and Dy-FeCo amorphous alloys has been studied using X-ray absorption spectroscopy and X-ray magnetic circular dichroism (XMCD). The Fe orbital and spin magnetic moments have been obtained for a range of alloy compositions by applying the sum rules to the XMCD spectra. The room temperature variations of the average components of the Fe moments as a function of Dy concentration and with the substitution of Fe by Co have been determined. A sharp reversal of the total magnetic moment was found at 28 +/- 1 at% Dy for both alloys. (C) 2000 Elsevier Science B.V. All rights reserved. [less ▲]

A laboratory-made malodour sensing system including 12 commercial tin oxide gas sensors (Figaro Engineering) is used to identify five typical sources of olfactive annoyance: printing houses, paint shop in a coachbuilding, wastewater treatment plant, urban waste composting facilities and rendering plant. In this work, all the samples are collected in the field from real malodours in uncontrollable conditions. The ability of the system to predict the origin of unknowns odoriferous samples is investigated. The test of various pre-processing data algorithms shows that the best classification results are obtained with a parameter free of the sensor base-line. The differences in sensor responses among the five odours are shown by icon plots and confirmed by principal component analysis, which highlights four representative clusters. Classification models calibrated by discriminant analysis and artificial neural network are validated on unknowns samples. Chemical relationships between the sensors and the classification results proves that the recognition is not fortuitous. In spite of the influence of environmental parameters, results demonstrate the ability of a simple system to detect and identify typical olfactive annoyances. [less ▲]

Most of the time, the definitions of minima, saddle points or more generally order p (p=0,...,n) critical points, do not mention the possibility of having zero Hessian eigenvalues. This feature reflects some flatness of the potential energy hypersurface in a special eigendirection which is not often taken into account. Thus, the definitions of critical points are revisited in a more general framework within this context. The concepts of bifurcation points, branching points, and valley ridge inflection points are investigated. New definitions based on the mathematical formulation of the reaction path are given and some of their properties are outlined. (C) 2000 American Institute of Physics. [S0021-9606(00)01110-7].

The effect of ammonia on the cough response to citric acid and on substance P release from C-fibers involved in this reflex was assessed. For a period from one to four days, piglets were exposed, in an inhalation chamber, to ammonia at a concentration of 15 or 30 ppm. During exposure, cough induction tests were done every two days. Recovery of the cough reflex after ammonia exposure was also determined. In a separate group of piglets exposed for 2 days to 30 ppm ammonia, substance P content was determined in bronchial and tracheal lavage fluids and in the tracheal and bronchial mucosa. Ammonia (30 ppm) was found to inhibit coughing significantly (the cough frequency was reduced by 64%) after a two-day exposure. In animals exposed for 4 days to this ammonia concentration, the recovery ranged from 3 to 7 days (mean: 5 days). The same ammonia concentration also caused the substance P content to increase significantly in bronchoalveolar lavage fluid (to 432% of its initial value) and tracheal lavage fluid (to 149%) and to decrease significantly in the tracheal mucosa (-58%), however the content in bronchial mucosa was not significantly affected (-43%). Exposure to 15 ppm ammonia had no effect on the frequency of citric acid-induced coughing. In conclusion, ammonia inhibits citric acid-induced coughing in pigs at concentrations that can be detected in piggeries. This inhibitory effect may be related to substance-P depletion in C-fiber endings [less ▲]

The "Diabetes Control and Complications Trial" (DCCT) demonstrated that intensive insulin therapy, by reducing HbA1c levels by about 2%, delays the onset and slows the progression of microangiopathic complications (by at least 50%) in patients with type 1 diabetes. The "Epidemiology of Diabetes Interventions and Complications" (EDIC) study recently showed that the reduction in the risk of progressive retinopathy and nephropathy resulting from intensive therapy during the DCCT not only persists, but is amplified for at least 4 years (reduction by about 80% when compared to diabetic patients previously treated with conventional therapy during the DCCT).

The management of the HIV infected child is nearly identical to the adult. Nevertheless, there are many clinical, immunological and virological details. Difficulties evoked for the adult have an even bigger importance, in view of the foreseeable longevity of these children under treatment. The reduction of the mother to child transmission, thanks to the AZT-caesarean association, must be continued. The use of anti-retroviral drugs during pregnancy requires a sustained attention because of the potential risks and benefits for the foetus and mother. The long-term impact of these drugs, in children exposed during pregnancy, remains unknown. The follow-up of these children therefore remains important. [less ▲]

The spray pattern characteristics of a number of different series of flat fan nozzles were investigated in two ways. The first method was to measure the distribution by means of a classic patternator with collecting cylinders. The second method consisted of numerical simulation of the distribution, by combining the real distributions of a number of nozzles. The real distribution was measured on a classic patternator for each nozzle separately. The numerical simulation is computerized and automated. This system allows both time and labour gains, and permits multiple trials with the same series of nozzles. Numerical simulation results are compared with spray distributions obtained on the patternator. The sprayed volumes of liquid were found to be significantly different from the simulated ones (level of significance 95%). However, the coefficient of variation characterizing the homogeneity of the spread volumes can be calculated using simulated volumes. This can be done once an empirical linear relation is established between the coefficients of variation obtained from simulated volumes and the ones obtained from measured volumes. [less ▲]

Autologous transplantation using peripheral blood stem cells (PBSCs) collected after chemotherapy, followed by growth factor administration (ASCT), is increasingly used in the treatment of non-Hodgkin's lymphoma (NHL). However, quantitative data regarding contaminating malignant cells in the harvests are still scarce. We prospectively investigated 37 diffuse large-cell lymphomas (DLCLs) in complete remission (CR) that were treated according to multicentric protocols at our centre. DNA was extracted from the diagnostic lymph node. The complementarity-determining region (CDR) III was sequenced and a patient-specific oligomer synthesized. Contamination was evaluated semiquantitatively by polymerase chain reaction (PCR) and was confirmed by a limiting dilution analysis. PBSCs collected at regeneration after administration of granulocyte colony-stimulating factor (G-CSF), steady-state bone marrow (BM) and peripheral blood samples at CR were compared. DNA was available in 37 patients, from which 22 rearrangements could be sequenced. Patients (n = 15) who had both the required follow-up samples and a suitable clonal marker were investigated. In two cases, the patient-specific PCR assay set up at diagnosis later gave false-negative results in samples in which clonal DNA was still detectable by other sets of primers. PBSC contamination was highly variable: 7 out of 15 patients showed a PBSC/BM ratio of NHL cells greater than 1 log, whereas 8 out of 15 patients showed no difference and could vary from one apheresis to another. Eight ASCTs were performed, five of which used highly contaminated PBSCs: four patients relapsed early, three with disseminated lymphoma. Thus, 50% of DLCLs in CR seem to mobilize significantly malignant cells at regeneration under G-CSF. Considering the higher numbers of cells reinfused, this translates into a much higher number of lymphoma cells reinfused when compared with autologous bone marrow transplantation (ABMT). However, their clonogenic potential remains unknown and, despite concerning observations in certain cases, it is still unclear whether this has an impact upon the outcome of ASCT. [less ▲]
