Background: Diarrhoea is a common medical problem affecting travellers to Asia, Africa and Latin America. The use of prophylactic antimicrobial agents may increase the risk of contracting resistant bacteria. Findings indicate that oligosaccharides, i.e. carbohydrate chains of 3-10 monosaccharides, reduce the risk of diarrhoea. Methods: We performed a placebo-controlled, double-blind study of a galacto-oligosaccharide, B-GOS (Bimuno®, Clasado Ltd, Milton Keynes UK), vs placebo for participants travelling to countries with a high/intermediate risk of diarrhoea for 7-15 days...

The life cycle of Severe Acute Respiratory Syndrome Coronavirus (SARS-CoV) involves a unique process called discontinuous transcription by which a set of 3' coterminal subgenomic mRNAs (sgmRNA) with identical 5' leader sequences can be generated. The current study demonstrates that the replication intermediates of minus strand of subgenomic RNA (sgRNA) can be readily recovered from SARS-CoV infected cells. A novel sgmRNA (M-1) was identified as a short version of membrane (M) gene. Transcriptional regulatory sequences (TRS) of SARS-CoV and Mouse Hepatitis Virus (MHV) sgmRNAs contain a species specific core element (CE)...

A tightly focused pulsed laser beam can locally modify the crystal structure inside the bulk of a scintillator. The result is incorporation of so-called optical barriers with a refractive index different from that of the crystal bulk, that can be used to redirect the scintillation light and control the light spread in the detector. We here systematically study the scintillation light transport in detectors fabricated using the Laser Induced Optical Barrier technique, and objectively compare their potential performance characteristics with those of the two mainstream detector types: monolithic and mechanically pixelated arrays...

La technologie médicale connaît une croissance exponentielle dans le milieu de la santé, mais elle n'a toutefois pas suivi le rythme observé dans des industries similaires, telles que l'aéronautique. Les nouvelles technologies ont le potentiel d'accroître la sécurité des patients, mais si leur introduction dans le milieu de la santé n'est pas coordonnée de manière réfléchie et proactive, la chaîne de la sécurité risque de s'en trouver affaiblie, ce qui exposera les patients à des risques. Trois concepts qui représentent la chaîne de la sécurité sont décrits...

Les préjudices que subissent les patients recevant des soins de santé représentent un fardeau considérable et peuvent avoir de graves répercussions sur les patients et les familles ainsi que sur la capacité des systèmes de santé de gérer l'accès des patients, leurs déplacements dans le système et les temps d'attente. L'intérêt pour la science de la haute fiabilité, mise au point à l'origine dans des secteurs comme l'aviation commerciale, qui ont un bilan exceptionnel en matière de sécurité, est une nouvelle tendance en soins de santé qui pourrait aider les organisations et les systèmes à atteindre le but ultime : zéro préjudice subi par les patients...

Les peuples des Premières nations, inuits et métis qui habitent au Canada sont aux prises avec de profondes disparités en matière de santé par rapport aux Canadiens non autochtones, et ce, dans presque toutes les mesures liées à la santé et au bien-être. Pour faire progresser les services de santé auprès des peuples autochtones, il faut passer à l'action dans tous les ordres de prestation des soins et des politiques en santé. Il est donc essentiel que les leaders et les prestataires des établissements, des systèmes et des installations de santé du Canada comprennent et prennent en main les déterminants de la santé propres aux peuples autochtones, y compris l'héritage du colonialisme et le racisme ancien et actuel...

En qualité de professionnels de la santé, nous sommes déterminés à assurer l'exploitation efficiente et efficace de nos établissements. Les outils dont nous disposons sont les structures bureaucratiques, les règles, les règlements, les politiques et, bien sûr, les mesures. Il n'y a rien de foncièrement pernicieux à avoir des établissements efficients, efficaces et mesurés, mais nous soutenons que l'humanité et l'authenticité manquent cruellement dans cet environnement, au prix d'un travail significatif...

PURPOSE: Patient selection for focal salvage remains difficult. Therefore, we developed and internally validated prediction models for biochemical failure (BF) and a composite endpoint (CE) following focal salvage high intensity focused ultrasound (HIFU) for radiorecurrent prostate cancer. MATERIALS AND METHODS: A prospective HIFU registry identified 150 cases (November 2006-August 2015). Recurrence was assessed with multiparametric magnetic resonance imaging (MRI) combined with template prostate mapping biopsies, targeted biopsies, or systematic transrectal ultrasound-guided biopsies...

Narrow band red-emitting A2GeF6:Mn(4+) (A = Na, K, Rb, Cs) phosphors were prepared through a two-step precipitation-cation exchange route using a K2MnF6 precursor as the Mn(4+) source. The phase purity, morphology, and constituent were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), X-ray photoelectric spectroscopy (XPS), and electron paramagnetic resonance (EPR) examination. Optical properties were investigated by photoluminescence spectra (PL and PLE) and high-resolution PL. A temperature-dependent PL examination was performed to investigate the electron-phonon coupling emission mechanism of Mn(4+) in these alkali fluorogermanates...

Data sets for concentrations of up to 22 elements including Pb, Cd, Ag, As, and Hg and several rare earth elements (REEs) in moss and surface soil from all over mainland Norway are analyzed by positive matrix factorization (PMF) and principal component analysis (PCA) with centered log-ratio transformation. Moss and soil samples collected in 2010 and 2005, respectively, show both a distinct long-range atmospheric transport PMF factor including a dominant Pb loading along with smaller loadings of Mo, Cd, Sb, and As, and a geogenic factor dominated by Ce, La, and Y...

The control of dispersity and size of metal particles deposited on substrate surface are always the major challenges for fabricating the efficient and stable metallic nanoparticles-decorated composite. Herein, we proposed a simple liquid-phase atomic layer deposition (L-ALD) method to obtain an atomic-layered MnO2 nanoparticles loaded palygorskite nanorod (MnO2@Pal), involving two-step procedures comprised of the solid-liquid interfacial reaction between organic manganese precursor and surface hydroxyl groups of palygorskite, and then a calcination treatment to activate surface Mn, which is used as a powerful adsorbent for recovery of REE ions from wastewater...

Pollution by heavy metals and more recently by rare earth elements (REE) and other minor elements (ME) has increased due in part to their high use in technological and electronic devices. This contamination can become very relevant in those sites where e-waste is improperly processed, as it is the case in many countries of the African continent. Exposure to some toxic elements has been associated to certain hematological disorders, specifically anemia. In this study, the concentrations of 48 elements (including REE and other ME) were determined by ICP-MS in whole blood samples of sub-Saharan immigrants with anemia (n=63) and without anemia (n=78)...

Vitamin-E-loaded nanoemulsion (Vit E-NE) was produced, and the effects of repeated oral administration of Vit E-NE (2 g/kg/day) for five days on hepatic gene expression and serum metabolites were investigated in rats. The mean particle diameter and zeta potential of Vit E-NE was 112 nm and 56 mV, respectively. Vit E-NE administered rats showed significantly higher triglyceride content than of standard diet (control) or Vit E control emulsion (Vit E-CE) group but no toxicity symptoms were found in blood biochemical analysis...

A novel assembly of a photocathode and photoanode is investigated to explore their complementary effects in enhancing the photovoltaic performance of a quantum dot solar cell (QDSC). While p-type nickel oxide (NiO) has been used previously, antimony selenide (Sb2Se3) has not been used in a QDSC, especially as a component of a counter electrode (CE) architecture that doubles up as the photocathode. Here, near infrared (NIR) light absorbing Sb2Se3 nanoparticles (NPs) coated over electrodeposited NiO nanofibers on a carbon (C)-fabric substrate was employed as the highly efficient photocathode...
