BACKGROUND Occupational physicians (OPs) have complex relationships with employees, employers, and the general public. OPs may have simultaneous obligations towards third parties, which can lead to variable conflicts of interests. Among the various studies of ethical issues related to OPs, few have focused on the Korean OPs. The aim of the present survey was to investigate the ethical contexts,...

Lo scopo di questo articolo è l’analisi delle proprietà di una costruzione ricorrente in spagnolo, come in numerose altre lingue geneticamente diverse, dove un argomento dativo non nucleare viene aggiunto ad una costruzione anticausativa e può essere interpretato come una causa accidentale o non intenzionale dell’evento, Prima si stabilisce che l’aggiunta di un argomento dativo ad una tipica st...

BACKGROUND In the absence of functional social security mechanisms for elderly people in Nigeria, elderly households are solely responsible for geriatric healthcare costs, which can lead to catastrophic health expenditures (CHE) - particularly among the poor. This study investigates the key determinants of CHE among poorly insured elderly households in Nigeria. We also offer some policy options...

BACKGROUND Policy interventions have been taken to protect households from facing unpredictable economic changes that may cause catastrophe in China. This study aims to estimate the change of overall proportion of households incurring catastrophic health care expenditure (CHE) and its income-related inequality in the rural areas of Shaanxi Province from 2008 to 2013. METHODS The data were dra...

BACKGROUND The effects of exposure time (20 versus 45 s) to a high concentration of cryoprotectant (7.0 mol/l ethylene glycol with 0.5 mol/l sucrose) and freezing rates (1200-10 300 degrees C/min) during rapid freezing of mouse pronuclear stage embryos on survival and development to blastocysts were investigated. Different freezing rates were achieved by directly plunging the straws (rapid free...

Oxyphytosterols (OPS) were fed to hamsters, at different concentrations, in order to observe their eventual incorporation into plasma, aorta, liver, kidneys and heart. The animals receiving the very high level (2500 ppm) presented 7beta-hydroxycampesterol, beta-epoxycampesterol, campestanetriol, 7-ketocampesterol, 7beta-hydroxysitosterol, beta-epoxysitosterol, sitostanetriol and 7-ketositostero...

There is no clear single factor to date that explains colony loss in bees, but one factor proposed is the wide-spread application of agrochemicals. Concentrations of 14 organophosphorous insecticides (OPs) in honey bees (Apis mellifera) and hive matrices (honey and pollen) were measured to assess their hazard to honey bees. Samples were collected during spring and summer of 2013, from 5 provinc...

The CFTR High Expresser (CHE) cells express eightfold higher levels of the cystic fibrosis transmembrane conductance regulator (CFTR) Cl(-) channel compared with neighboring enterocytes and were first identified by our laboratory (Ameen et al., Gastroenterology 108: 1016, 1995). We used double-label immunofluorescence microscopy to further study these enigmatic epithelial cells in rat intestine...

BACKGROUND To enable occupational physicians (OPs) to make use of scientific information in the decision-making process, evidence-based occupational health practice is stimulated. AIMS To study the questions which arise in daily practice of OPs, and to evaluate the possible contribution of evidence-based medicine (EBM) strategies to answer these questions. METHODS Observation of 20 OPs duri...
