It is now irrefutable that air pollution caused by large amounts of respiratory particulates (Particulate Matter less than 10 µm in aerodynamic diameter, PM10) has numerous undesired consequences on human health. Although air quality degradation far away from the African continent in the US and in Europe caused by high concentration of African dust is seen as a major health threat although most of these countries are very distant from the Sahara; no estimates of PM10 levels near the Saharan dust source are available. Based on horizontal visibility observations which are reduced by the presence of dust in the atmosphere, PM10 levels are estimated during 2005 at Niamey-Airport, Niger. It appears that excessive concentrations of particles are very important both in magnitude and frequency as the 24-hour PM10 thresholds established by the US EPA National Ambient Air Quality Standards and the EU Limits Values for Air Quality were exceeded 103 and 67 times, respectively. The average yearly concentration is far above air quality standards and estimated to 92 µg m-3 for PM10. These very high particulate levels are likely to represent an important public health threat and should be considered as a major environmental risk. [less ▲]

Episyrphus balteatus DeGeer (Diptera, Syrphidae) is an abundant and efficient aphid-specific predator. We tested the electroantennographic (EAG) response of this syrphid fly to the common aphid alarm pheromone, (E)-beta-farnesene (E beta F), and to several plant volatiles, including terpenoids (mono- and sesquiterpenes) and green leaf volatiles (C6 and C9 alcohols and aldehydes). Monoterpenes evoked significant EAG responses, whereas sesquiterpenes were inactive, except for the aphid alarm pheromone (E beta F). The most pronounced antennal responses were elicited by six and nine carbon green leaf alcohols and aldehydes [i.e., (Z)-3-hexenol, (E)-2-hexenol, (E)-2-hexenal, and hexanal]. To investigate the behavioral activity of some of these EAG-active compounds, E. balteatus females were exposed to R-(+)-limonene (monoterpene), (Z)-3-hexenol (green leaf alcohol), and E beta F (sesquiterpene, common aphid alarm pheromone). A single E. balteatus gravid female was exposed for 10 min to an aphid-free Vicia faba plant that was co-located with a semiochemical dispenser. Without additional semiochemical, hoverfly females were not attracted to this plant, and no oviposition was observed. The monoterpene R-(+)-limonene did not affect the females' foraging behavior, whereas (Z)-3-hexenol and E beta F increased the time of flight and acceptance of the host plant. Moreover, these two chemicals induced oviposition on aphid-free plants, suggesting that selection of the oviposition site by predatory hoverflies relies on the perception of a volatile blend composed of prey pheromone and typical plant green leaf volatiles.

Myostatin (MSTN), a transforming growth factor beta superfamily member, is an essential factor for the growth and development of muscle mass. The protein functions as a negative regulator of muscle growth and is related to the so-called double-muscling phenotype in cattle, where a series of mutations renders the gene inactive. One particular breed of pigs, the Belgian Pietrain, also shows a heavily muscled phenotype. The similarity of muscular phenotypes between the double-muscled cattle and Pietrain pigs indicated that MSTN may be a candidate gene for muscular hypertrophy in pigs. In this study, we sequenced and analysed the complete MSTN gene from 45 pigs of five different breeds, including the heavily muscled Pietrain breed at one extreme and the Meishan and Wild boar breeds at the other extreme. In total, 7626 bp of the porcine MSTN gene were sequenced, including the 5' and 3' UTR. Fifteen polymorphic loci were found, three of which were located in the promoter region, five in intron 1 and seven in intron 2. Most mutations were found when comparing the obtained MSTN sequence with porcine MSTN sequences already published. However, one polymorphism located at position 447 of the porcine MSTN promoter had a very high allele frequency in the Pietrain pig breed and disrupted a putative myocyte enhancer factor 3 binding site. Real-time PCR using Sybr Green showed that this mutation was associated with expression levels of the MSTN gene in m. longissimus dorsi at an age of 4 weeks. [less ▲]

Prophylaxis for infective endocarditis has been recommended on the basis of the supposed pathophysiology of the disease, although no randomised clinical trial has confirmed its efficacy. Bacteraemia resulting from daily activities is much more likely to cause infective endocarditis than bacteraemia associated with invasive medical procedures. As a result, recommendations for antibiotic prophylaxis tend now to be severely restricted. [less ▲]

Repeated observation of "mothflies" at CHU Brugmann (Horta site hospital in Brussels) is not an isolated incident. Many public buildings have been infested by these Diptera of the Psychodidae Family. Although the species currently seen in Belgium is not a danger to human health, any infestation should be swiftly eradicated so as to limit the risks of a massive proliferation, source of hygiene problems and of potential bacterial dissemination. A good knowledge of adult and larval biology allows the potential sites of infestation to be quickly identified. The method to be envisaged to solve the problem will combine different approaches such as removing the risk factors (decomposing organic matter), monitoring egg-laying sites, applying caustic soda-based products and possibly treating with insecticide.

Adaptation of photosynthesis in marine environment has been examined in two strains of the green, picoeukaryote Ostreococcus: OTH95, a surface/high-light strain, and RCC809, a deep-sea/low-light strain. Differences between the two strains include changes in the light-harvesting capacity, which is lower in OTH95, and in the photoprotection capacity, which is enhanced in OTH95. Furthermore, RCC809 has a reduced maximum rate of O(2) evolution, which is limited by its decreased photosystem I (PSI) level, a possible adaptation to Fe limitation in the open oceans. This decrease is, however, accompanied by a substantial rerouting of the electron flow to establish an H(2)O-to-H(2)O cycle, involving PSII and a potential plastid plastoquinol terminal oxidase. This pathway bypasses electron transfer through the cytochrome b(6)f complex and allows the pumping of "extra" protons into the thylakoid lumen. By promoting the generation of a large DeltapH, it facilitates ATP synthesis and nonphotochemical quenching when RCC809 cells are exposed to excess excitation energy. We propose that the diversion of electrons to oxygen downstream of PSII, but before PSI, reflects a common and compulsory strategy in marine phytoplankton to bypass the constraints imposed by light and/or nutrient limitation and allow successful colonization of the open-ocean marine environment.

Pleural involvements are common and various respiratory diseases including inflammatory, infectious, occupational, or neoplastic pathological entities...Pleural thickening and pleurisy are usual radiological presentation. Etiological diagnosis imposes a vast and sometimes difficult exploration and it, especially since the conventional imaging by radiology, ultrasound, scanning and nuclear magnetic resonance has no specific diagnostic criteria for pleural malignancy. The metabolic imaging by positron emission tomography (PET) has been gradually positioned in the decision-making algorithm exploration of the pleural disease due to its excellent sensitivity in the diagnosis of malignant pleurisy (88.8%-100%). The analysis of chemistry, bacteriology and cytology pleural fluid makes a significant contribution to the diagnostic approach. However, although inescapable, thoracocentesis has a diagnostic sensibility not exceeding 62%. Moreover, the sensibility of the pleural blind needle biopsies does not exceed 51%. So, thoracoscopy, more invasive, is often justified to precise pleural disease with a diagnostic sensitivity greater than 95%. Finally, despite the diagnostic arsenal available, over 10% of pleurisies remain unknown etiology. [less ▲]
