La soie est une matière utilisée par les Malgaches depuis bien avant la colonisation. Cette soie est fabriquée à partir de la collecte de cocons des papillons du genre Borocera spp., ver à soie sauvage. On connaît une dizaine d’espèces de vers à soie sauvages endémiques à Madagascar. Ces lépidoptères polyphages se nourrissent surtout des feuilles de Uapaca bojeri et d’autres plantes telles que Dodonea madagascariensis et Psidium guyava. Les critères morphologiques se révèlent insuffisant pour identifier cette diversité d’espèces de vers à soie, surtout au niveau des stades immatures. Afin de pallier à cette incapacité d’identifier les espèces, des méthodes de marqueurs moléculaires, en particulier la RAPD (Random Amplified Polymorphic DNA) et iSSR (inter Simple Sequence Repeat), ont été appliquées. En plus de l’identification des espèces, une étude de la diversité et de la distribution des vers à soie suite à la collecte dans plusieurs forêts éloignées de plusieurs de kilomètres les unes des autres (Arivonimamo, Ambatofinandrahana, Antananarivo). Cette étude a été menée dans le cadre de la conservation de ces espèces de vers à soie endémiques en milieu. Afin d’augmenter durablement les populations de vers à soie endémiques dans les forêts de Uapaca, il est important de déterminer les espèces en présence et les capacités de dispersion de ces dernières. Les techniques d’identification moléculaires développées permettront d’orienter les stratégies de gestion des populations de Borocera et des méthodes de gestion de l’écosystème, appropriables par les gestionnaires et les communautés locales des la forêt à Uapaca bojeri.

Design and method : Office blood pressure (OBP) and home BP (HBP) were measured in 70 kidney transplant patients (KT) (43 men/27 women;KT>1 year), all were treated with antihypertensive drugs (mean number: 2±1). Mean age: 56±11 years, mean graft survival: 7±6.6 years, mean GFR: 65.6±24 ml/min, diabetes:27% and current smoking:11.5%. HBP (Omron M6) was measured during 7 days following the OBP measurement, mean HBP was calculated from day 2 to day 7. Uncontrolled BP was defined by OBP>=140-90 (>=130-80 when diabetes) and HBP>=135-85 (>=130-80 when diabetes). The day of the OBP measurement and the last day of HBP, patients collected 24h- urine and recorded at the same time their food and beverage consumption. Sodium and potassium were measured in urines and their intakes were quantified through food records. Urinary and diet Na+, K+ did not differ between the two urine collections 7 days apart. Results: 16 patients(23%) had controlled BP (OBP and HBP) while 34 (49%) remained with sustained hypertension (SHT) despite treatment, 14 (20%) had masked uncontrolled hypertension (MHT, OBP<140-90 and HBP>=135-85,130-80 if diabetes for both).When comparing the controlled and SHT, no differences were found with age, graft survival, BMI, GFR, calcineurin inhibitors or number and type of antihypertensive drugs. The groups did not differ by their sodium excretion (154±93 vs 162±88 mmol/24h) but well by their K excretion significantly higher in controlled patients (68±17 vs 53±20 mmol/24h,p=0.018) giving a Na/K ratio higher in SHT (3.2±1.3 vs2.2±1.2,p=0.03). Diet analysis showed significantly higher intakes of K (fruits, vegetables) in controlled patients (3279±753 vs 2208±720 mg/24h,p=0.010) whereas both groups consumed on average 9 g/24h of salt. When controlled for age, BMI and Na excretion, Home systolic BP was inversely and significantly correlated with urinary potassium (- 0.46;P=0.002) while no correlation was found with urinary Na.Conclusions: KT patients remaining hypertensive and well controlled patients had both high salt consumption. However, well controlled patients differed by significant higher potassium intakes and excretion. Urinary Na/K ratio could be a useful tool contributing to an optimal BP control in KT patients. However, impact of increasing potassium intakes on uncontrolled BP in KT has to be validated by prospective randomized studies [less ▲]

Cet article vise à comprendre dans quelles situations les associations disposent d'un avantage institutionnel sur les autres types de producteurs (privés et publics) et à identifier sur quelles caractéristiques propres aux associations se basent leurs avantages. Une première section décrit certains échecs du marché, c'est-à-dire certaines circonstances dans lesquelles les entreprises for-profit ne semblent pas être les mieux placées pour assurer la production des biens ou services. Une deuxième section présente l'action publique pour pallier ces limites et identifie ses faiblesses. Après ces deux détours nécessaires, nous relevons, dans une troisième section, en quoi, selon le courant nord-américain des théories NPOs, les associations présentent des atouts particuliers pour dépasser les limites du marché et de l'Etat. On y relève également les désavantages inhérents à leur action. Enfin, une dernière section synthétise les différents arguments présentés en expliquant pourquoi, dans le contexte belge, les associations constituent un secteur productif important, présent dans de nombreuses branches d'activité, le plus souvent aux côtés de prestataires publics ou for-profit.

The prevalence of cattle seropositive to bovine herpesvirus-4 (BHV-4) is high in Belgium. In Belgian farms, clinical signs associated with BHV-4 infection essentially involve the genital tract and consist mainly of postpartum metritis or metroperitonitis. The role of BHV-4 in abortion has not been definitively demonstrated but epidemiological and experimental facts suggest its involvement. A seroepidemiological investigation was therefore conducted as a case-control study to compare the seroprevalences of BHV-4 infections in the aborted-cow population and in a randomly selected control group in the province of Liege (Belgium). The seroprevalence (17.2%) in aborted cows was significantly higher than that of the control group (10.0%). The odds ratio (OR) was 1.87 (1.06 < 3.30). BHV-4 infection is therefore considered as a risk factor for abortion in cows. [less ▲]

This study investigates the involvement of the c-cbl proto-oncogene during the first stages of the apoptotic process. We have already shown that a c-Cbl aptotosis-related protein of 90 kDa (CARP 90) is detected very rapidly in the cytoplasm as well as in the nucleus of murine thymocytes after hydrocortisone (HC) treatment. We report here that this protein appeared as well after in vivo treatment of mice by gamma-irradiation or injection of anti-CD3 monoclonal antibody, two potent thymic apoptosis inductors, providing a close relationship between the occurrence of apoptosis and the appearance of CARP 90. We showed that CARP 90 and p120(cbl) share numerous epitopes strikingly suggesting that CARP 90 is coded by c-cbl. In addition, KO mice do not sustain CARP 90 appearance. We finally showed that CARP 90 contains N- and C-terminal end epitopes of p120(cbl) which suggests that CARP 90 is an alternative spliced form of c-cbl. This protein was also observed under gamma-irradiation in tissues of different origin, which enlarges the physiological significance of this phenomenon. The very rapid CARP 90 appearance under apoptotic conditions in the nucleus of cells originating in different tissues makes this protein if not a possible new actor of the apoptotic process, at least an interesting marker of this process.

Surgery for abdominal aortic aneurysm may be challenging when rare renal or venous anomalies are present. This article reports two similar cases of aortic abdominal aneurysm associated with horseshoe kidney and left-sided inferior vena cava treated with a transperitoneal approach. Preoperative knowledge of the anatomic situation enabled appropriate aneurysm repair. Operative strategy is discussed. This report describes an uncommon venous vascular malformation complex and stresses the importance of computed tomography imaging not only in assessing the characteristics of the aneurysmal disease but also in detecting variations in pertinent vascular or parenchymal anatomy.

The association between aortic stenosis and digestive angiodysplasia has been described for the first time by Heyde in 1958. This entity is thus known as Heyde's syndrome. In many instances, the recurrent small intestinal bleeding originating from angiodysplasia stopped after aortic valve replacement. We report two cases of patients presenting with a recurrent small intestinal bleeding originating from digestive angiodysplasia and suffering from aortic stenosis. Diagnosis of both pathologies is well documented in both cases. The replacement of the aortic valve by a biologic prosthesis stopped the bleeding. Prior to aortic valve replacement, the two patients suffered severe recurrent blood loss from intestinal angiodysplasia. The treatment of aortic stenosis greatly favored both cardiac and general status. We recommend aortic valve replacement with a biologic prosthesis prior to intestinal resection in patients presenting with Heyde's syndrome. We stress on the fact that anticoagulants must be stopped in order to minimize the risk of further bleeding. [less ▲]

Osteochondrosis (OC) is the most common developmental orthopaedic disease in horses and represents a major problem to the horse industry. The complete mechanism of this multifactorial disease is not yet elucidated, but it is accepted that OC lesions are the result of intrinsic genetic and external factors. The aim of the present work was to evaluate the relationship between breeding management and OC. Breeding conditions were recorded, and a radiological examination was performed in 223 foals. Feeding practice and housing management were analysed in a multivariate model to determine risk factors for OC in three periods: gestation, birth to weaning and weaning to one-year-old. The major breakthrough of this study is the significant relationship between OC development and (1) the maternal nutrition during gestation and (2) the type of housing of the foals during their first year. It appears that mares fed with concentrates during gestation are more likely to produce foals that are subsequently affected by OC compared with other mares (P<0.05). Foals housed exclusively at pasture until one year of age are significantly less affected than foals exclusively housed in box or, alternatively, in box and at pasture (P<0.05). These results underline the role of the energy metabolism and the level of exercise in the aetiologic process of the disease, and help to develop preventive strategies during the crucial period of gestation to one year of age of the foal.

Increasing age, several co-morbidities, environmental contamination, antibiotic exposure and other intestinal perturbations appear to be the greatest risk factors for C. difficile infection (CDI). Therefore, elderly care home residents are considered particularly vulnerable to CDI. The main objective of this study was to evaluate and follow the prevalence of C. difficile in a Belgian nursing home. During a 4-month period, stool samples from a group of 23 elderly care home residents were collected weekly. A C. difficile microbiological detection scheme was performed along with an overall microbial biodiversity study of the faeces content by Targeted Metagenomic analysis. Surfaces and diary meals were also sampled in order to determinate the possible role of environmental and food contamination in the acquisition of CDI. Culture of samples was performed in a selective medium cycloserine cefoxitin fructose cholate. An identification of the isolated colonies was done by PCR detection of tpi, tcdA, tcdB and cdtA genes. Toxic activity was confirmed by a cytotoxic immunoassay. Further characterization was performed by PCR ribotyping. The Metagenomic analysis was targeted on the v1-v3 hyper-variable region of 16S rDNA. The taxonomical assignment of the populations was performed with MOTHUR and Blast algorithms. C. difficile was not detected in any of the tested meals or surfaces samples. For the stools samples, 6 of the 23 controlled residents were identified as C. difficile carriers. The isolates belonged to 4 different PCR ribotypes, including types 020 and 027. This unique association of classical microbiology protocol with pyrosequencing allowed to follow C. difficile in patients and to identify several other bacterial populations whose abundance is correlated with C. difficile.
