Background: Rectal adenocarcinomas surgery morbidity and mortality might be impaired by neoadjuvant therapy. We performed this retropsective study to be compared with the PROCARE study running afterwards. Methods: We performed a retrospective study of 95 patients operated on for rectal denocarcinoma in a single institution during the period 2007-2009. We used logistic regression to estimate the relationship between possible predictive parameters of AL. Results: The laparoscopic approach is favored in 63.1% of the cases with a conversion rate of 11.6%, mainly in man (6 out of 7). For low rectal cancer though, laparotomy was the first choice (92.3%). From a carcinological point of view, laparoscopy allowed a complete tumor resection according to the PME (n=27) and TME (n=26) standards. Multivariate analysis revealed that women, lower BMI, lower rectum tumor, laparoscopic surgery, neoadjuvant treatment and anal suture were associated with higher risk of AL. The mean hospital stay was 15.4 days (3 – 46 days). In-hospital mortality was 3.1%. Adjuvant chemotherapy was completed in 42.1% of the patients. Despite these treatments, we registered a recurrence rate of 26.6%. Of these, 72% were distally localized and 12% exclusively locally. Among the patients operated on by laparoscopy, there was one local recurrence and one local with distant metastases (3.7%). The one- and three-years survival rates were 91.5% and 80.4% respectively. Conclusions: Our study showed a higher rate of AL than expected (18%). In our series recorded in PROCARE-Home, our leak rate has dropped to 10%. It may be indicating a positive effect of PROCARE.

In this work, physico-chemical properties and photocatalytic activity of three types of dried or dried and calcined TiO2 materials, synthesized by the cogelation method, were studied: (i) a pure TiO2 xerogel ; (ii) TiO2 xerogels doped with Ag ; (iii) TiO2 xerogels co-doped with Ag and P. The presence of silver nanoparticles was observed by transmission electron microscopy (TEM) and the oxidation state of silver after calcination was examined by temperature-programmed reduction (TPR) measurements. The physico-chemical properties of xerogels were characterized by X-ray diffraction (XRD), diffuse reflectance UV-Vis spectroscopy (DR UV-Vis) and from nitrogen adsorption-desorption isotherms. The photocatalytic activity of the samples was quantified for the p-nitrophenol degradation under visible light. [less ▲]

Recent research suggests that sleepiness and mind-wandering—the experience of thoughts that are both stimulus-independent and task-unrelated—frequently co-occur and are both associated with poorer cognitive functioning. Whether these two phenomena have distinguishable effects on task performance remains unknown, however. To investigate this question, we employed the online experience sampling of mind-wandering episodes and subjective sleepiness during a laboratory task (the Sustained Attention to Response Task; SART), and also assessed mind-wandering frequency and sleep-related disturbances in daily life using self-report questionnaires. The results revealed that the tendency to experience mind-wandering episodes during the SART and daily life was associated with higher levels of daytime sleepiness and sleep-related disturbances. Importantly, however, mind-wandering and sleepiness were independent predictors of SART performance at both the within- and between-individuals levels. These findings demonstrate that, although mind-wandering and sleepiness frequently co-occur, these two phenomena have distinguishable and additive effects on task performance. [less ▲]

In recent years, many accidents have occurred between cyclists and in-race motorcycles, even yielding fatal injuries. The accidents and the potential aerodynamics issues have impelled the present authors to perform dedicated wind-tunnel measurements and Computational Fluid Dynamics (CFD) simulations to assess cyclist drag reduction when followed by one, two or three motorcycles. The 3D steady-state Reynolds-Averaged Navier-Stokes simulations with the standard k-ε model are validated by the wind-tunnel tests. The cyclist drag reduction goes up to 8.7% for a single trailing motorcycle and to 13.9% for three trailing motorcycles at a distance of 0.25 m behind the cyclist. This distance is not uncommon in elite races, as evidenced by the many recent accidents. The effect by a single following motorcycle at realistic short distances d=0.25 m (8.7%), d = 0.5 m (6.4%) and d=1 m (3.8%) is larger than that by a following car at realistic short distance d=5 m (1.4%). Therefore it could be argued that in-race motorcycles are not only more dangerous but also aerodynamically more influential. This study reinforces the necessity for the International Cycling Union to change the rules concerning in-race motorcycles, not only to avoid accidents but also to avoid unwanted aerodynamic benefits.

Inositol 1,4,5-trisphosphate 3-kinase C (ITPKC) is the last identified member of the inositol 1,4,5-trisphosphate 3-kinases family which phosphorylates inositol 1,4,5-trisphosphate into inositol 1,3,4,5-tetrakisphosphate. Although expression and function of the two other family members ITPKA and ITPKB are rather well characterized, similar information is lacking for ITPKC. Here, we first defined the expression of Itpkc mRNA and protein in mouse tissues and cells using in situ hybridization and new antibodies. Surprisingly, we found that cells positive for ITPKC in the studied tissues express either a multicilium (tracheal and bronchial epithelia, brain ependymal cells), microvilli forming a brush border (small and large intestine, and kidney proximal tubule cells) or a flagellum (spermatozoa), suggesting a role for ITPKC either in the development or the function of these specialized cellular structures. Given this surprising expression, we then analyzed ITPKC function in multiciliated tracheal epithelial cells and sperm cells using our Itpkc knock-out mouse model. Unfortunately, no significant difference was observed between control and mutant mice for any of the parameters tested, leaving the exact in vivo function of this third Ins(1,4,5)P3 3-kinase still open.

Plant root-knot nematode interaction studies are performed on several host plant models. However, even though root-knot nematodes interact with trees, no perennial woody model has been explored so far. We show here that poplar (Populus tremula x Populus alba) grown in vitro is susceptible to Meloidogyne incognita as this nematode is able to penetrate, to induce feeding sites and to reproduce in poplar roots. As analyzed by Raman spectromicroscopy, the cell walls of the giant cells, with typical characteristics of transfer cell walls, were not lignified and were composed mainly of pectin and cellulose. To better depict the poplar-nematode interaction at the molecular level, a quantitative RT-PCR analysis was performed to study changes in poplar gene expression in galls compared to non-infected roots. Three marker genes, reported for other plant hosts, including expansin A, histone 3.1 and asparagine synthase, were conserved for poplar-nematode interaction. In addition, the down-regulation of four genes coding for enzymes of the lignin biosynthesis pathway was evidenced in galls, suggesting a modification in lignin composition within galls developed in poplar roots. Together, this study shows that poplar is a suitable model host for specific traits of tree-nematode interaction. [less ▲]

Many significant intellectual developments have taken place in 20th century European social theories. Notably the first Frankfurt School and Bourdieu’s work have successfully shown how workers, social actors, etc. are alienated or dominated by capitalist social structures. But according to Habermas, neither perspective successfully allows for the possibility that people could contribute to their own emancipation. The emergence of new forms of social resistance to domination such as those embodied by the Indignados, Anonymous, Femen, the practitioners of alternative economy, movements of unemployed people or illegals compels us to envisage the possibility for emancipation, but how? In this paper we explore opportunities for accounting for this by considering the work of a range of other European social theorists, more specifically Boltanski whose critical intent is embodied in his pragmatic sociology, and evident in his coining and use of the concept of the world. In addition we will consider Latour’s own pragmatic stance as we believe that despite his disinterest in new social movements, his work, informed by pure immanence, might offer potential solutions. But we would argue that even in these innovations there is either a persistent tendency to imagine emancipation primarily as a return to some ideal state or a lack of critical engagement with alienation. In response, we propose a materialist renewal, which will lead us to ponder on the political role of sociologists. [less ▲]

From Marx to Althusser, the materialist approach has tended to assume that individuals (that is, workers, proletarians and other social actors), unconsciously reproduce the social structures of capitalism which alienate them. It is assumed that individuals accept the conditions forced upon them and no longer seek to rebel against a world which substantially impoverishes their labour, their spirit and their creativity. In this paper, I will try to show that by dint of favouring almost exclusively Marx's concept of alienation, there is a considerable risk that materialist thought will adopt only a negative path. Whilst I acknowledge Marx’s significance to materialism, I wish to argue that his stance should be combined with that of the anarchist and libertarian French thinker Proudhon. Proudhon has succeeded in presenting a conception of the worker as more than just alienated. Workers can also cooperate and experience a reciprocity seemingly at odds with the character of capitalism. Under Proudhon’s influence materialism takes a positive turn, enabling us to avoid falling into the utopianism that the theory of social economy employs to critique capitalism – a utopianism that renders its critique even less effective than that of Marx.
