The infection of foetal thymus with coxsackievirus B4 (CV-B4) E2 has been studied ex vivo by using CD-1 mice on foetal day 14, as a ready source of organs for experimentation to investigate the hypothesis of the role of thymic viral infections in the pathogenesis of type 1 diabetes. The replication of CV-B4 E2 in murine foetal thymus organ cultures has been demonstrated by evaluating the levels of positive- and negative-stranded viral RNA in cells by using a real-time quantitative RT-PCR method and by determining titres of infectious viral particles in culture supernatants for 7 days post-infection (p.i.). Staining of tissue sections with an anti-cytokeratin antibody and haematoxylin-eosin showed that CV-B4 infection had no visible effect on cell survival and organ integrity. Cell counts in mock- and virus-infected foetal thymus organ cultures increased from day 1 through day 7, and live cell numbers were comparable in both conditions as shown by Trypan blue exclusion test and 7-amino-actinomycin D staining of thymocytes. Compared with controls on day 7 p.i., cytofluorometric analyses on cells from CV-B4 E2-infected foetal thymus organ cultures displayed a marked increase in the percentage of the most immature CD3(-)CD4(-)CD8(-) thymocytes, and a decrease in the percentage of immature CD3(-)CD4(+)CD8(+) cells, together with an increase in the percentage of mature CD3(+)CD4(+) and CD3(+)CD8(+) cells. These data show that CV-B4 E2 disturbs T-cell maturation and differentiation processes in infected murine foetal thymus organ cultures and provide evidence of a suitable system to investigate the effect of viruses in T-cell differentiation.

Notre recherche a pour but de mieux repérer ce qui semble faciliter chez l'enfant tout venant son développement linguistique et communicationnel, afin de mettre en place des stratégies éducatives adaptées aux enfants présentant des troubles du langage. Dans une étude longitudinale des interactions mère-enfant chez trois enfants tout-venant entre 1 an 6 mois et 3 ans, notre équipe s'est penchée sur un phénomène interactionnel au croisement de l'appropriation du système linguistique et de son usage : les rectifications. Nos analyses soulignent le rôle clé de la mère ainsi que les similarités et les différences entre les dyades. La sensibilisation à ces dimensions de la communication auprès de parents d'enfants dysphasiques dans le cadre d'un projet de guidance parentale pourrait favoriser la mise en place de formes d'interaction facilitant le développement langagier et communicationnel des enfants.

Models beyond the Standard Model (bSM) often involve elaborate Higgs sectors, which can be a source of CP violation. It brings up the question of recognizing in an efficient way whether a model is CP violating. There is a diffuse belief corroborated by all specific multi-Higgs models considered so far that the issue of explicit CP invariance can be linked to the existence of a basis in which all coefficients are real. Here, we prove that this belief is not justified. We present a CP-conserving three-Higgs-doublet model for which no real basis exists. The generalized CP symmetry of this model is of order 4, which leads to the peculiar property of the extra neutral Higgs bosons of being neither CP-even nor CP-odd but “half-odd” under this symmetry transformation.

Background Despite recent improvements in prevention, medical treatment [1]and endovascular aortic repair , invasive surgery associated with cardiopulmonary bypass (CPB) remains the best option of treatment for some patients. The aim of this study is to make a review of the specific CPB protocols associated with these invasive surgical approaches, based on our clinical experience and according to the recent literature. Up to now, these protocols are not supported by evidence based in medicine (EBM) [2] or in perfusion (EBP). Discrepancies can be observed regarding target temperature , selective cerebral protection , CPB circuit concept and arterial cannulation sites . Variables guidelines are suggested concerning regional flow , transfusion requirements [3], coagulation monitoring blood gas management[4] as for cerebral and CPB monitoring tools. Conclusions In the absence of EBM and EBP in the aortic surgery field, the short and long terms clinical outcomes of the patients elected to invasive surgery for aortic diseases must guide and substantiate our choices of techniques and of CPB protocols.

We summarize the results of a multiwavelength observing campaign on the massive eclipsing binary CPD-41° 7742, another remarkable object in the young open cluster NGC 6231. Our campaign relies on high resolution echelle spectroscopy, narrow-band optical photometry, and XMM-Newton X-ray observations. Combined with the spectroscopic analysis, the light curve analysis provides a direct measurement of the masses and sizes of the system components. However, the most outstanding results come from the XMM observations. Our 180 ks campaign towards NGC 6231, and CPD-41° 7742, provides an unprecedented phase coverage of such a close early-type binary. The EPIC-MOS light curves almost fully cover the 2.4 day period of the system and the brightness of the object is sufficient to yield a time resolution as tight as 1 ks. The X-ray flux presents clear variations along the orbit, that we interpret as the signature of an unusual wind interaction. We indeed expect that, in this O+B system, the dominant primary wind crashes into the secondary surface, leading to a wind-photosphere interaction. As a strong support to our interpretation, we provide a geometrical model that associates an extra X-ray emission to the secondary inner surface. Though quite simple, the present model matches the main features of the X-ray light curve. [less ▲]

Despite the importance of the African tropical rainforests as a hotspot of biodiversity, their history and the processes that have structured their biodiversity are understood poorly. With respect to past demographic processes, new insights can be gained through characterizing the distribution of genetic diversity. However, few studies of this type have been conducted in Central Africa, where the identification of species in the field can be difficult. We examine here the distribution of chloroplast DNA (cpDNA) diversity in Lower Guinea in two tree species that are difficult to distinguish, Erythrophleum ivorense and Erythrophleum suaveolens (Fabaceae). By using a blind-sampling approach and comparing molecular and morphological markers, we first identified retrospectively all sampled individuals and determined the limits of the distribution of each species. We then performed a phylogeographic study using the same genetic data set. The two species displayed essentially parapatric distributions that were correlated well with the rainfall gradient, which indicated different ecological requirements. In addition, a phylogeographic structure was found for E. suaveolens and, for both species, substantially higher levels of diversity and allelic endemism were observed in the south (Gabon) than in the north (Cameroon) of the Lower Guinea region. This finding indicated different histories of population demographics for the two species, which might reflect different responses to Quaternary climate changes. We suggest that a recent period of forest perturbation, which might have been caused by humans, favoured the spread of these two species and that their poor recruitment at present results from natural succession in their forest formations.

The CphAII protein from the hyperthermophile Aquifex aeolicus shows the five conserved motifs of the metallo-β-lactamase (MBL) superfamily and presents 28% identity with the Aeromonas hydrophila subclass B2 CphA MBL. The gene encoding CphAII was amplified by PCR from the A. aeolicus genomic DNA and overexpressed in Escherichia coli using a pLex-based expression system. The recombinant CphAII protein was purified by a combination of heating (to denature E. coli proteins) and two steps of immobilized metal affinity chromatography. The purified enzyme preparation did not exhibit a β-lactamase activity but showed a metal-dependent phosphodiesterase activity versus bis-p-nitrophenyl phosphate and thymidine 5'-monophosphate p-nitrophenyl ester, with an optimum at 85°C. The circular dichroism spectrum was in agreement with the percentage of secondary structures characteristic of the MBL αββα fold. [less ▲]

Patients with rectal cancer are at high risk of disease recurrence despite neoadjuvant radiochemotherapy with 5-Fluorouracil (5FU), a <br />regimen that is now widely applied. In order to develop a regimen with increased antitumour activity, we previously established the <br />recommended dose of neoadjuvant CPT-11 (three times weekly 90 mgm 2) concomitant to hyperfractionated accelerated <br />radiotherapy (HART) followed by surgery within 1 week. Thirty-three patients (20 men) with a locally advanced adenocarcinoma of <br />the rectum were enrolled in this prospective phase II trial (1 cT2, 29 cT3, 3 cT4 and 21 cNþ). Median age was 60 years (range 43– <br />75 years). All patients received all three injections of CPT-11 and all but two patients completed radiotherapy as planned. Surgery <br />with total mesorectal excision (TME) was performed within 1 week (range 2–15 days). The preoperative chemoradiotherapy was <br />overall well tolerated, 24% of the patients experienced grade 3 diarrhoea that was easily manageable. At a median follow-up of 2 <br />years no local recurrence occurred, however, nine patients developed distant metastases. The 2-year disease-free survival was 66% <br />(95% confidence interval 0.48–0.83). Neoadjuvant CPT-11 and HART allow for excellent local control; however, distant relapse <br />remains a concern in this patient population. [less ▲]
