#1
M Raimonet, T Cazier, V Rocher, A M Laverman
Although a higher oxidation rate for nitrite than for ammonia generally prevents nitrite accumulation in oxic waters, nitrite concentrations in the Seine River (1-31 μM) exceed European norms. We investigated the kinetics of in situ ammonia- and nitrite-oxidizing communities in river water and wastewater treatment plant (WWTP) effluents to determine the role of pelagic nitrification in the origin and persistence of nitrite downstream of Paris. The main source of nitrite is the major Parisian WWTP, and its persistence, up to tens of kilometers downstream of the plant, is explained by low ammonia and nitrite oxidation rates and high river flow...

José Paranaguá de Santana
This essay stresses the importance of undertaking a critical analysis of international cooperation for health based upon reflections on diplomacy, acknowledging the ethical limits and possibilities of cooperation within this context. It emphasizes the importance of adopting an historical perspective, highlighting the circumstances surrounding the consolidation of the current international system, whereby, after two world wars, the victorious countries created the United Nations Organization, which today brings together all the world's nations, notwithstanding the fact that the majority of countries are in favor of significant changes to its institutional framework...

BACKGROUND: Ultrasound is a non-invasive and readily available tool that can be prospectively applied at the bedside to assess muscle mass in clinical settings. The four-site protocol, which images two anatomical sites on each quadriceps, may be a viable bedside method, but its ability to predict musculature has not been compared against whole-body reference methods. Our primary objectives were to (i) compare the four-site protocol's ability to predict appendicular lean tissue mass from dual-energy X-ray absorptiometry; (ii) optimize the predictability of the four-site protocol with additional anatomical muscle thicknesses and easily obtained covariates; and (iii) assess the ability of the optimized protocol to identify individuals with low lean tissue mass...

Temporary passive immunity such as serotherapy against venoms requires the full knowledge of all venom's components. Here, four venoms from Moroccan common yellow scorpions belonging to Buthus occitanus, subspecies tunetanus, paris, malhommei, and mardochei, all collected in four different restricted areas, were analysed in deep. They were fractionated by reversed-phase high-performance liquid chromatography (RP-HPLC) and their molecular masse profile determined by off-line MALDI-TOF mass spectrometry. Characterisation of their main components was achieved by enzyme-linked immunosorbent assay (ELISA) using specific antisera against the major lethal scorpion toxins identified so far, i...

Samusocial de Paris works daily with disadvantaged people. It has identified a number of obstacles which prevent access to care for these people: notably prejudices, the complexity of access to rights, congestion within the accommodation system, a lack of interpreters and health care mediators, as well as failures in the legal system.

The onset of lactation in dairy cows is characterized by severe negative energy and protein balance. Increasing Met availability during this time may improve milk production, hepatic lipid metabolism, and immune function. The aim of this study was to evaluate the effect of feeding ethyl-cellulose rumen-protected methionine (RPM; Mepron, Evonik Nutrition and Care GmbH, Hanau-Wolfgang, Germany) on the performance of dairy cows during prepartum and early-lactation periods. Sixty multiparous Holstein cows were used in a block design and assigned to either a control or an ethyl-cellulose RPM diet...

BACKGROUND: The neuropeptide transmitter nociceptin, which binds to the nociceptin/orphanin FQ peptide (NOP) receptor, is a core component of the brain's antistress system. Nociceptin exerts its antistress effect by counteracting the functions of corticotropin-releasing factor, the primary stress-mediating neuropeptide in the brain. Basic investigations support a role for medications that target nociceptin receptors in the treatment of alcohol use disorders. Thus, it is of high interest to measure the in vivo status of NOP receptors in individuals with alcohol use disorders...

BACKGROUND: Socioeconomic deprivation is associated with reduced use of antenatal resources and poor maternal outcomes with pregnancy. Research examining the association between socioeconomic deprivation and use of obstetric anesthesia care in a country providing universal health coverage is scarce. We hypothesized that in a country providing universal health coverage, France, socioeconomic deprivation is not associated with reduced use of anesthetic care during pregnancy and delivery...

Recently, seven single nucleotide polymorphisms (SNPs) of ARNTL, TIM and PER3 genes were found associated with affective temperaments in bipolar disorder patients. This study aimed to test whether a) the same associations appear in a non-clinical sample; b) the SNPs are related to other affective dimensions; c) the SNPs underpin the associations between chronotype and affective temperaments/dimensions. Three hundred thirty-eight university students completed the Temperament Scale of Memphis, Pisa, Paris and San Diego Auto-questionnaire, the Centre for Epidemiological Studies Depression Scale, the Perceived Stress Scale, the General Health Questionnaire, the Seasonal Pattern Assessment Questionnaire and the Composite Scale of Morningness...

The transfer or transition from paediatric care to adult medicine is, for a large number of adolescents and young adults being monitored for a rare and/or chronic pathology, as well as for the care teams, a critical period in their medical journey and in their life. It is both an individual and a public health issue, with medical-economic consequences. At the hôpital Necker-Enfants malades in Paris, a specific programme has been implemented aimed at the patients and carers.

Bcl-2-protein family members are essential regulators of apoptosis. Anti-apoptotic Bcl-2 proteins ensure cell survival via different mechanisms, including via binding of pro-apoptotic Bcl-2-family members and the modulation of intracellular Ca(2+)-transport systems. Many cancer cells upregulate these proteins to overcome the consequences of ongoing oncogenic stress. Bcl-2 inhibition leading to cell death, therefore emerged as a novel cancer therapy. Different Bcl-2 inhibitors have already been developed including the hydrophobic cleft-targeting BH3 mimetics, which antagonize Bcl-2's ability to scaffold and neutralize pro-apoptotic Bcl-2-family members...
