On 14 June 2004, Benin ratified a new Code on Persons and Family, adapting its previous dual legal system to the requirements of international human rights law. For the purpose of this article, I chose to focus on inheritance conflicts as a back door to questioning the implementation of a law directly inspired by international human rights standards and principles. When it comes to inheritance disputes, are human rights respected in Benin? What are the discourses of the judges, the lawyers, and the notaries regarding this new Code? How is it implemented and what are the obstacles to it? Combining both qualitative interviews with family members and participant observation in the courtrooms, I compiled a series of case studies, supplemented by interviews with judicial officials. These sets of data allowed me to grasp how laws are enforced and interpreted, and how citizens deal with their families and with the justice system. [less ▲]

The Internet has become an essential communication medium upon which billions of people rely every day. However, necessary evolution of the Internet has been severely limited by reliability constrains and social-economic factors. Experts fear that current growth rates will threaten the future of the Internet as a whole, despite the fact that new core technologies already exist. Network virtualization presents a promising approach to overcome ossification and facilitate service deployment for a future Internet. Exploring this approach, we present a prototype implementation which realizes a subset of the 4WARD virtual network (VNet) architecture, allowing multiple VNets to coexist on top of a shared physical infrastructure. We discuss the functionality of our prototype and demonstrate experimental results to assess its performance. [less ▲]

Udder health is usually considered as a health and economic problem for farmers. We now consider that mastitis is the result of many factors related to the environment, the pathogen and the host. What may have been forgotten in the process is the fact that nowadays, the main interface with mastitis is the farmer, and their knowledge about mastitis is very heterogeneous. This reflexion has led to the creation of a technical and pedagogical pack called “Mammipack” which contains different tools, from all actors of the dairy chain. We included small charts explaining the most important risk factors identified through epidemiology, good dairy practices and its effect on milk flow, milking machine check-up, how-to for mastitis milk sample, a how-to for performance records use for udder health management, a resume on genetic selection of sires and mastitis, charts upon nutrition factors and their main effect on udder physiology during lactation and dry-off, resume on veterinary drugs good management in the farm. Small laminated sheets upon milk sampling for bacteriology and teats evaluation were also joined in order to be use in parlors, sterile sampling tubes were also given in the pack. A mastitis record pad was designed to record the main clinical forms and the treatment chosen. Eventually, the book Udder Health® was added to have a complete modern look on that problem in dairy farms. 25 farmers were selected on a voluntary base by 12 veterinarians, and they answered to questionnaires about their main practices regarding herd structure, mastitis treatment, and southern Belgium main 19 risk factors. They had to answer basic questions concerning udder health on 15 points. They agreed to keep a record of all next mastitis cases in their farms and take milk samples for bacteriology each time at day 0 and day 21 during 3 months. The main objective is to show to a group of dairy farmers that mastitis could take several different forms from one farm to another, in term of incidence, pathogens and clinical forms. One other purpose is to show the difficulty to have bacteriological cure, even when physical cure has happened. After all, one collateral objective was to create the Mammipack®, designed for farmers and vets to increase their ability to collaborate on mastitis management through most dairy chain actors’ expertise.

In the Bocq basin, eastern tributary of the Meuse, restoration works consist of making 20 obstacles passable to improve the free movement of fish and sediment. This presentation focuses on a particular case study involving river restoration in a groundwater abstraction zone. In the sixties, a reach of more than 600 meters of the Bocq was completely channelized in order to avoid any risk of contamination of the nearby important drinking water well field area. Ecological quality was consequently impoverished due to the loss of natural habitats (streambed and banks made of concrete and masonry). In addition, the hydraulic conditions (high flow, low depth) make it totally insurmountable for fish. The restoration project started with a 3-year period of consultation with the water abstraction owner to finally reach an agreement on a restoration project taking into account the need of protection of the water abstraction. The project consisted on building rock weirs at regular interval in order to create a succession of 23 steps and pools. Furthermore, various habitats schemes were implemented such as fish shelter, rock berms for aquatic vegetation, and spawning gravel introduction. In addition a small dike and an expansion area for flooding have been completed to protect the water abstraction. This project is being monitored on the basis of geomorphological and ecological analysis. Geomorphological monitoring focuses on the bedload transport with an analysis of flood and the clogging of the gravel layer. Ecological monitoring is based on two indicators (macroinvertebrates and fishes) as well as the analysis of microhabitats. The first results show an improvement after 1 year. [less ▲]

A fast and stable algorithm to compute a highly robust estimator for the logistic regression model is proposed. A criterium. for the existence of this estimator at finite samples is derived and the problem of the selection of an appropriate loss function is discussed. It is shown that the loss function can be chosen such that the robust estimator exists if and only if the maximum likelihood estimator exists. The advantages of using a weighted version of this estimator are also considered. Simulations and an example give further support for the good performance of the implemented estimators.

Prostate cancer is the second leading cause of cancer death in men. Although androgen ablation remains the most effective management option, most patients with advanced disease progress to castration resistant prostate cancer (CRPC), within two years of treatment. This results, in part, from the increase in the anti-apoptotic molecules expression following androgen withdrawal. Among the proteins involved in this phenomenon, clusterin, also known as testosterone repressed message-2 (TRPM- 2), which exists in two forms: a pro-apoptotic nuclear form (nClU) and a secreted survival factor (sClU). In our study we investigated the role of the secreted form of clusterin in preventing cells from TNFα-induced apoptosis. For this, we first generated a sCLU inducible stable prostatic cancer MLL rat cell line by using the Tet-On gene expression system. With this model we revealed a new mechanism by which sCLU promotes survival in androgenindependent prostate cancer cells, implicating its receptor megalin and the Akt survival pathway. By applying a comparative proteomic analysis in the androgen-independent epithelial cell line MLLTet-sClu induced to overexpress sClu or non induced control-cells, we identified five proteins known to play a role in cancer. These proteins candidates are heat shock proteins Hsp90 and Hsp70, osteopontin (bone sialoprotein, OPN), proliferating cell nuclear antigen (PCNA) and ADP-ribosylation factor 1 (Arf1). Altogether, our data provide new mechanistic insight in sCLU dependent activation of the major survival pathway upregulated in refractory prostate cancer. The identification of the new sCLU protein targets open new avenues for more research to elucidate the significance of clusterin in prostate cancer progression and resistance to therapy. [less ▲]

Effects of different psychological stimuli on oxytocin (OT) and vasopressin (AVP) secretion are reviewed in animals and in humans. The secretion of neuropituitary hormones is also discussed in various psychiatric diseases such an anorexia nervosa, bipolar disorder, schizophrenia and obsessive-compulsive disorder. AVP and OT are secreted into the hypophyseal portal circulation by neurons which project from the paraventricular nucleus to the external zone of the median eminence. AVP and OT-containing neurons in the suprachiasmatic and paraventricular nuclei project to limbic areas, including the hippocampus, the subiculum, the ventral nucleus of the amygdala and the nucleus of the diagonal band. Specific AVP receptors which are pharmacologically different from the pressor and antidiuretic AVP receptors have been found in the anterior pituitary. OT receptors have been identified in a variety of forebrain sites. The neurohypophyseal secretion is regulated by the cholinergic muscarinic, histaminergic and beta-adrenergic systems. Stress alters the secretion of one or more of the hypothalamic factors which interact at the pituitary to increase the secretion of ACTH. AVP and OT have been shown to modulate the effect of Corticotropin-Releasing Factor (CRF) on ACTH secretion and appear to play a key role in mediating the ACTH response to stress. Although AVP is a relatively weak secretagogue for ACTH, it markedly potentiates the activity of CRF both in vitro and in vivo. The role of OT is more complex. In vitro, OT stimulates ACTH release at high doses whereas in human it inhibits ACTH secretion at low doses. The type of stressor appear to determine the relative importance of these secretatogues in ACTH response. Several recent studies indicate that psychological stressors display a similar degree of variety of secretagogue release patterns as was found earlier for physical stressors. A bewildering array of technique produces a bewildering array of conclusions. In rats, OT may be an important secretagogue during a novel stimulus, whereas the role for AVP is less clear. Indeed two studies out of ten suggest a stimulating role for AVP. In response to frustration and submission, OT and AVP are secreted. Regarding social isolation, results are difficult to interpret and the role of AVP could be species-dependent. In contrast plasma OT levels do not change. After restraint, ACTH release is primarily mediated by the active increase of OT and AVP does not appear to play a role. When restraint is associated with moderate levels of physical components and during immobilisation, all two secretagogs are involved in the ACTH response. With fear, ACTH response appears to be driven by OT. In humans, one study indicates that high emotionality women increase plasma OT in response to uncontrollable noise. Various neuroendocrine dysregulations have been observed in psychiatric disease. Either an increase or a decrease of the hypothalamic-pituitary-adrenal (HPA) function have been described in several illnesses. Effects of OT appear to be reciprocal to the effects of AVP. OT has been called the "amnestic" neuropeptide due to its capacity to attenuate memory consolidation and retrieval. AVP exhibits a central activating action on mood, memory and selective attention. Underweight patients with anorexia nervosa have abnormally high levels of centrally directed AVP and reduced OT levels. These modifications could enhance the retention of cognitive distortions of aversive consequences of eating. Patients with bipolar disorder show a biphasic secretion of AVP. Depressive episodes are associated with decreased vasopressinergic activity whereas manic episodes involve an increased release. AVP might be responsible for an increased catecholamine activity. In addition, lithium could act as an antagonist to AVP. In schizophrenic patients, studies using the apomorphine stimulation suggest increased oxytoninergic and decreased vasopressinergic functions. These findings are consistent with the beneficial role of AVP on schizophrenic symptoms noted in several trials. The increased OT could be responsible for "positive" symptomatology such as delusions and hallucinations. Obsessive compulsive disorder (OCD) includes a range of cognitive and behavioral disturbances that could be influenced by OT. In animals, several studies have emphasized the role of AVP in promoting repetitive grooming behaviors and maintaining conditioned response to aversive stimuli. In OCD patients, one study have reported that AVP/OT ratio was negatively correlated with symptom severity. However, an independent report found similar AVP concentrations in OC patients without a personal or family history of tic disorder and in normal subjects. Whether these modifications are only a consequence of the central disturbances or whether those peptides could participate in the pathogenesis of these affections remains to be elucidated. [less ▲]
