Peritoneal adhesions represent an important clinical challenge in gastrointestinal surgery. Peritoneal adhesions are a consequence of peritoneal irritation by infection or surgical trauma, and may be considered as the pathological part of healing following any peritoneal injury, particularly due to abdominal surgery. The balance between fibrin deposition and degradation is critical in determining normal peritoneal healing or adhesion formation. Postoperative peritoneal adhesions are a major cause of morbidity resulting in multiple complications, many of which may manifest several years after the initial surgical procedure. In addition to acute small bowel obstruction, peritoneal adhesions may cause pelvic or abdominal pain, and infertility. In this paper, the authors reviewed the epidemiology, pathogenesis and various prevention strategies of adhesion formation, using Medline and PubMed search. Several preventive agents against postoperative peritoneal adhesions have been investigated. Their role aims in activating fibrinolysis, hampering coagulation, diminishing the inflammatory response, inhibiting collagen synthesis or creating a barrier between adjacent wound surfaces. Their results are encouraging but most of them are contradictory and achieved mostly in animal model. Until additional findings from future clinical researches, only a meticulous surgery can be recommended to reduce unnecessary morbidity and mortality rates from these untoward effects of surgery. In the current state of knowledge, pre-clinical or clinical studies are still necessary to evaluate the effectiveness of the several proposed prevention strategies of postoperative peritoneal adhesions.

Depuis la parution en 1966 de L’analyse structurale du récit, l’usage que fait le discours d’information du récit a donné lieu à un très grand nombre de travaux. Emportée par ce succès, la notion de récit y subit par ailleurs un fléchissement conceptuel qui peut aller jusqu’à désigner la « super forme » implicite à laquelle les médias de masse renverraient nécessairement lorsqu’ils relaient événements ou informations. Un important ensemble de recherches ( inspirées des théories littéraires, notamment la narratologie, des recherches sur le récit « postmoderne » ou, plus récemment, du travail de Paul Ricoeur ou Michel de Certeau sur les liens entre récit et vie quotidienne), ont fait évoluer la manière dont la catégorie « récit » est susceptible de questionner le discours d’information. Cet article propose une lecture épistémologique de cette évolution, et rend compte des conditions d’émergence des enjeux actuellement questionnés dans l’étude des récits d’information. Il montre comment se sont imposées les questions liant récit, mythe et histoire collective puis, plus récemment, récit et fiction, et expose les raisons pour lesquelles, aujourd’hui, ces questions sont déportées vers une approche plus pragmatique, centrée sur la narration en tant qu’elle est un processus de médiation. L’ensemble de ces réflexions impose de clarifier une situation notionnelle parfois confuse ; l’article propose ainsi de réarticuler ensemble récit et narration en leur adjoignant la notion de récitation.

This paper presents a review of studies that were aimed at determining which brain regions are recruited during visual self-recognition, with a particular focus on self-face recognition. A complex bilateral network, involving frontal, parietal and occipital areas, appears to be associated with self-face recognition, with a particularly high implication of the right hemisphere. Results indicate that it remains difficult to determine which specific cognitive operation is reflected by each recruited brain area, in part due to the variability of used control stimuli and experimental tasks. A synthesis of the interpretations provided by previous studies is presented. The relevance of using self-recognition as an indicator of self-awareness is discussed. We argue that a major aim of future research in the field should be to identify more clearly the cognitive operations induced by the perception of the self-face, and search for dissociations between neural correlates and cognitive components.

OBJECTIVE: The aim of the study was to evaluate the use of proviral DNA as a source of viral genetic material for genotypic coreceptor tropism testing (GTT). METHODS: GTT consisted of bulk V3 sequencing followed by geno2pheno interpretation with the interpretative cut-off [false positive rate (FPR)] set at 5 and 10%. GTT was performed for 165 patients with a viral load of >500 HIV-1 RNA copies/mL on simultaneously collected plasma RNA and proviral DNA, and for 126 patients with a viral load of <500 copies/mL on current proviral DNA and pretreatment plasma RNA. Phenotypic tropism testing (PTT) results were available for 142 samples. RESULTS: In the simultaneous RNA/DNA comparison, concordance in prediction was 95.2% (at FPR 10%) and 96.4% (at FPR 5%). Six RNA-R5/DNA-X4 and two RNA-X4/DNA-R5 discordances were observed at an FPR of 10%, and six RNA-R5/DNA-X4 discordances were observed at an FPR of 5%. In the longitudinal RNA/DNA comparison, concordance was 88.1% (at FPR 10%) and 90.5% (at FPR 5%). Eight RNA-X4/DNA-R5 and seven RNA-R5/DNA-X4 discordances were seen at an FPR of 10%, and 10 RNA-R5/DNA-X4 and two RNA-X4/DNA-R5 discordances at an FPR of 5%. The overall concordance of RNA GTT with PTT was 82% (at FPR 10%) and 83% (at FPR 5%). The overall concordance of DNA GTT with PTT was 85% (at both 10 and 5% FPRs). CONCLUSIONS: GTT produced highly concordant tropism predictions for proviral DNA and plasma RNA. GTT on proviral DNA offers a promising approach for tropism prediction in clinical practice, particularly for the assessment of treated patients with low or suppressed viraemia. [less ▲]

Two High Speed Steels (HSS) have been studied both having chemical compositions closed one to another. Both HSS grades exhibited similar matrix/carbides microstructure in the industrial as-cast conditions, except for M7C3 eutectic carbides only observed in one grade and fine pearlite only found in the other grade. Equilibrium diagrams were obtained from Thermodynamical simulations to enhanced predicted phase transformations whereas Differential Thermal Analysis was performed on both alloys in order to determine their crystallization behaviour in non equilibrium conditions. Light microscopy and Electron microscopy associated with microprobe analyses were done to characterize the microstructure of both alloys. Thermal treatments with related bulk hardness assessments were carried out to enhance conditions for pearlite formation at the end of the casting route. In continuous cooling conditions obtained from DTA simulations, the matrix of both as-cast HSS grades is composed of eutectic carbides, martensite and retained austenite, these phases exhibiting similar chemical compositions. The introduction of an intermediate isothermal stage in the solid state within the DTA cooling sequence leads to the formation of a fine pearlite phase mainly located in the vicinity of M2C eutectic carbides on one HSS grade. The origin of this fine pearlite is discussed in this paper. [less ▲]

Dans l’écriture même du scénario, dans les designs des personnages, dans les références des décors, dans les registres d’animation et dans la mise en scène, Walt Disney a placé intentionnellement des éléments de rhétorique qui permettront à un disours de canonisation de s’instaurer quasi immédiatement au moment de la sortie des films. Cela témoigne bien entendu d’une très grande intelligence de Disney des attentes du public et des institutions (au sens large). Cet article entend détailler cette stratégie d'auto-canonisation.

Distal lower leg soft tissue defect is frequently a challenge to repair, particularly on the tibial crest. The coverage of this kind of lesion has some limitations because of regional minimal blood supply and paucity of local soft-tissue flaps. The perforator pedicled propeller (PPP) method tries to find a new place in lower leg reconstruction in bringing similar tissues at the recipient site and avoiding long and difficult free flap transfer or muscular sacrifice. The authors report on the use of PPP method for a tibial crest exposure after trauma and for a soft tissue defect with osteomyelitis on the tibial crest. [less ▲]

The consumption of wildlife meat is an important source of animal protein for rural and urban population in Congo. A survey on bushmeat trade was undertaken in 21 municipal markets during four weeks, in Brazzaville. The objective of this study was to define the traders’ profile and to evaluate the quantities of games and meat merchandised on the municipal markets. The study methodology combined two approaches: a quantitative one using a questionnaire as principal tool for collecting data, and a qualitative one associating informal survey methods via individual or group interviews. The results showed that women were the most involved in this trade (52%). Markets trader’s monthly income was estimated at 210,428 (US$420) ± 49,128 (US$98,256) FCFA. On average, the bushmeat traders’ were 39 ± 10 years old and 69% of them attended the two levels of secondary education. During four weeks, 3,711 animal carcasses were recorded on the 21 surveyed markets, representing almost 35,790 kg of biomass. Overall, 35 animal species were identified, including 9 the hunting of which was prohibited. The mammals constituted 93.8% of total number of hunted animals, with three dominant orders as the artiodactyls (49.2%), the rodents (22.6%) and the primates (17.7%), of which the Cephalophus, the Potamochoerus, the Atherurus and the Cercopithecus were the most represented. It was also noticed that trapping, an activity which leads to great losses, becomes very important, followed by be helpful alternatives to meet Congolese demand for bushmeat. For a sustainable management of the Congo’s faunic resources, this study suggests the introduction gun-hunting. The Congo-Ocean Railway and the National Road n°2 were used regularly in the transportation of game, to a 72% level. The district of Niari, Lekoumou, Sangha and Pool were the main sources of supply. At the present time, the meat quantities offered in Brazzaville markets don’t seem to be reduced because hunting areas extend always further, often to the detriment of protected areas. Despite the fact that such business squarely growths and shows evidence of overexploitation, activities promoting game farming and breeding of domestic species, in Brazzaville suburbs, are needed to mitigate the impact of bushmeat trade.

The eradication of poverty and hunger is the first of the Millennium Development Goals (MDGs) established by the United ations. One of the Rwanda’s commitments is the fulfillment of this goal as indicated in its own long term Vision 2020 aimed at enabling Rwandans to emerge from under-development and poverty status by achieving economic growth objectives in combination with social indicators objectives. As it has been researched that the major cause of poverty in developing countries is the high rate of their population growth, this paper is aimed at assessing the fertility preferences and the level of family planning in Rwanda as a tool to poverty eradication. The paper also presents some challenges and some other pathways to improve the socioeconomic welfare of Rwandan population. In this paper descriptive methods have been used to present and analyze data and a Pearson Chi square test has been used to study the association between variables. The results shows that the knowledge of contraception is universal (99%) but the use of contraception methods for family planning is still very low (37%). On the average fertility preferences are 3.2 children which are good if realized. The general conclusion that emerges from the study is that in order to reduce poverty, family planning is a must but lot more are to be done. Among other things, a focus on increasing rural income and agriculture output. [less ▲]

OBJECTIVE: We investigated the association between the proportion of long-chain n-3 polyunsaturated fatty acids (PUFA) in plasma phospholipids from blood samples drawn at enrollment and subsequent change in body weight. Sex, age, and BMI were considered as potential effect modifiers. METHOD: A total of 1,998 women and men participating in the European Prospective Investigation into Cancer and Nutrition (EPIC) were followed for a median of 4.9 years. The associations between the proportion of plasma phospholipid long-chain n-3 PUFA and change in weight were investigated using mixed-effect linear regression. RESULTS: The proportion of long-chain n-3 PUFA was not associated with change in weight. Among all participants, the 1-year weight change was -0.7 g per 1% point higher long-chain n-3 PUFA level (95% confidence interval: -20.7 to 19.3). The results when stratified by sex, age, or BMI groups were not systematically different. CONCLUSION: The results of this study suggest that the proportion of long-chain n-3 PUFA in plasma phospholipids is not associated with subsequent change in body weight within the range of exposure in the general population.
