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 ▲]

In the Walloon Region of Belgium, a commlttee of Intervention has been created to Investigate problems of pesticide contamination of various catchments use for drinking water production. This commlttee Involves the Agricultural Research centre - Wallonla (CRA-W, project coordinator) and sorne University experts. It ls funded by the Société Publique de Gestion des Eaux (SPGE). The diagnosis method, base on the AQUAPLAlNE method (Arvalis - France), conslsts of 4 steps. The first step Is the preparation of diagnosls (at the office) that takes into account the paper r1sk of active ingredients. and thelr uses, the identification of the agrtcultural parcels, the collection of cartographie and numeric data, the description of the hydrogeological and pedological contexts and the study of the meteorologlcal data ln relation with the period of pollution. The second step conslsts of maklng a plot diagnosls (on the field) ta Identify the way of transfer inside the plot and collecting data. At the thlrd step, the people who can apply ppp treatment close to the catchment are met (farmers and city services). Information are coJ!ected on treatments applied and on the state of parcels. Based on the hypathesls of pollution cause, the committee proposes solution to solve the problem. One of the catchment that has been investigated by the commlttee is located at Biesmerée, (Namur province, ln Belglum). A temporally contamination was caused by 4 pesticides: chlortoluron, isoproturon, trifluralln and diflufenlcan. After Investigations, it seems that the pollution was probably due ta the hydrogeologlcal context . As the river Is locally perched over the aqulfer, the presence of Poly-aromatic hydrocarbons (PAHs) could be due ta the Infiltration of surface water inside the catchment or/and to the presence of a sinkhole temparaHy activated durlng river flood period. Infiltration rate has ta be assessed and river bank Impermeabilization Is recommended [less ▲]

Blockade of venous drainage in the cavernous sinus, which may play a pivotal role in the pathophysiology of cluster headache (CH), could be triggered by local inflammation. It could also be favored by a constitutional narrowness of the cavernous sinus region. Before exploring the latter with magnetic resonance imaging (MRI), we determined whether external morphometric skull measures are different among CH patients (n = 25), healthy volunteers (n = 21), and migraine patients (n = 20). All subjects were males of comparable age distribution. Six measures were taken: inion-nasion perimeter, inion-nasion distance over the vertex; distance between the upper ends of tragus; diameter at the level of the temporal fossa; diameter at mid inion-nasion perimeter at ear level; and inion-nasion diameter. CH patients had significantly smaller values than healthy subjects and/or migraine patients in all but one measure (ANOVA and Duncan's post-hoc analysis). This may suggest that they have a narrower anterior/middle cranial fossa, and possibly a narrower cavernous sinus loggia, which needs to be confirmed by a quantitative MRI study. [less ▲]
