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.

Lake Kivu is a deep meromictic and oligotrophic tropical African lake with a permanent thermal- and haline stratification with huge accumulations of dissolved CO2 and CH4 (ca. 300 km3 and 60 km3, respectively) in the deep anoxic monimolimnion (from 60 o 480 m depth). Although there are a wealth of information on the ecology of small eukaryotes and their trophic role on Kivu, available information on prokaryotic planktonic assemblages is scarce. Molecular analysis of archaeal and bacterial communities showed a vertical segregation imposed by the permanent redoxcline. In relation to Bacteria, Actinobacteria, Betaproteobacteria, Green Sulfur Bacteria and Bacteroidetes were the most commonly retrieved groups. For Archaea, a marked dominance of Thaumarchaeota and Crenarchaeota (75% of all archaeal OTUs) over Euryarchaeota was observed. In the anoxic hypolimnion, Euryarchaoeta (Methanosarcinales and Methanocellales) lineages together with Miscellaneous Crenarchaeotic Group phylotypes were mainly recovered. In turn, Thaumarchaeota phylotypes were recovered in oxic and suboxic waters. CARDFISH analyses over the first 100 m revealed the dominance of Bacteria (51.4% – 95.7% of DAPI-stained cells), especially Actinobacteria (epilimnion), Betaproteobacteria (oxic-anoxic interface) and Bacteroidetes (upper hypolimnion), over Archaea (1.0% – 4.5%; maximum abundances at the oxic-anoxic interface). In turn, flow cytometry evidenced the dominance of HNA cells in the euphotic layer, whereas the proportion of LNA cells increased with depth. HNA and LNA populations were still observed in the anoxic hypolimnion suggesting facultative or strict anaerobic metabolisms. The detection of distinct depth maxima of nitrate, nitrite, archaeal amoA and Marine Thaumarchaeota 16S gene copy numbers together with regularly detection of deep maxima of 3H-Thymidine uptake, and the presence of low-light adapted GSB species point towards a strong link of N, C, and S cycles in the redoxcline of Lake Kivu.

Antigen expression and purification are laborious, time consuming and frequently difficult steps in the process of antibody production. In the present study, we developed a method avoiding these two steps. This method relies on the injection of histocompatible living cells stably expressing the antigen as a cell surface type II transmembrane fusion protein. A vector, nicknamed pCD1-CD134L, was constructed to express the antigen fused at the carboxyterminal end of the human CD134 ligand (CD134L) type II transmembrane protein on the surface of eucaryotic cells. This vector was shown to induce cell surface expression of epitopes from human c-Myc (soluble protein), uterogloblin-related protein 1 (secreted protein) and CD94 (type II transmembrane protein). Using this vector, we developed a method to produce antibodies without antigen production. The flowchart of this method is as follows: (i) cloning of the antigen in the pCD1-CD134L vector; (ii) production of a histocompatible cell line stably expressing the CD134L-antigen fusion protein; (iii) testing for cell surface expression of the fusion protein by targeting the CD134L carrier; and (iv) prime-boost immunisation with living cells expressing the fusion protein. This method was successfully used for production of polyclonal antibodies raised against Ixodes ricinus calreticulin (secreted protein) in mice and for production of monoclonal antibodies raised against an epitope of Vaccinia virus A56 (type I transmembrane protein) protein in rat. The present study is the first to demonstrate the use of a type II transmembrane protein as a carrier for cell surface display of antigens. [less ▲]

Jean-Jacques Rousseau est né avec la conscience de son altérité : fils d’horloger, citoyen de Genève, il se sent dès son plus jeune âge différent du monde qui l’entoure. Par sa « réforme » au début des années 1750, il transformera officiellement cette altérité en faire-valoir. Pourtant, quand résonne le glas de la condamnation de ses œuvres (Émile et le Contrat social) en 1762, l’homme jusque-là différent, se sent étranger, incompris, seul contre tous, comme en témoigne sa correspondance. Cet article se donne pour objectif d’étudier ce sentiment d’altérité et d’étrangeté à travers la correspondance personnelle de Jean-Jacques Rousseau de 1762 à 1765 (soit de la condamnation de l’Émile et du Contrat social jusqu'au départ pour l’Angleterre chez David Hume).

La crise financière mondiale qui a éclaté en 2008 et les effets désastreux qu’elle a occasionnés sur le secteur minier en RDC (qui avait été placé au centre des politiques de croissance et de lutte contre la pauvreté) posent avec encore plus d’acuité la question de la diversification de la structure économique dans une province comme le Katanga. Au problème de la vulnérabilité d’un tel modèle de croissance s’ajoute le constat qui est fait dans cette étude du manque d’effet d’entrainement de l’activité des grands groupes miniers sur le reste de l’économie locale, en termes de développement des capacités productives et de création d’emplois.

The efficacy of grafting materials for alveolar bone regeneration procedures has been repeatedly corroborated by clinical and scientific evidence. Although an ever growing number of biomaterials are available on the market, the origins, material characteristics, bioactivity and osteoconductive properties of these products are not always known by clinicians, hence often hampering an adequate product selection. The purpose of this contribution was to provide an overview of five different types of osteoconductive grafting materials frequently used in dentistry (Bio-Oss®, Cerasorb M™, Bone Ceramic®, Natix®, Genos®) and to summarize their physico-chemical and morphological characteristics at the macro- and micro-scale. Furthermore, the influence of these properties on the in vivo behaviour of these biomaterials is discussed. The results of this study are presented as data sheets, which may prove helpful for clinicians in the design of their treatment strategies. [less ▲]
