introduction: the most common mode of rabies virus transmission is through a bite wound or contact of broken skin with saliva of a rabid animal. various other routes of virus transmission include exposure of mucous membranes (i.e. eyes, nose, and mouth) to infected saliva of a rabid animal, aerosol transmission, and corneal transplantation. laboratory workers during work with rabies virus and v...

cow’s milk whey consists of many protein components and some of them are antigens to human and known to modulate immune responses. enzymatic hydrolysis is a useful method to modify proteins with allergenicity. the objective of this study was to identify whether the in vitro enzymatic hydrolysis could reduce the allergenicity of whey protein concentrates (wpc). in  this study, wpc were hydrolyze...

Background: It is showed that methamphetamine has harmful effects on male reproductive system. The aim of this study was to investigate the effects of methamphetamine administration on testis weight, sperm count, sperm morphology, and chromatin status as well as sperm apoptotis followed by the cytochemical tests in a mouse model. Materials and Methods: Twenty four NMRI male mice were divided in...

To assess the impact of endometriosis on intracytoplasmic sperm injection (ICSI) outcome, we have retrospectively evaluated 980 ICSI cycles, comparing the results of women with and without endometriosis. A total of 101 cycles was identified in which various degrees of endometriosis were involved, and in the remaining 879 cycles, male infertility was the only cause of infertility. Ejaculated spe...

We use a global 3-D chemical transport model (GEOS-Chem) to interpret new aircraft, surface, and oceanic observations of methanol in terms of the constraints that they place on the atmospheric methanol budget. Recent measurements of methanol concentrations in the ocean mixed layer (OML) imply that in situ biological production must be the main methanol source in the OML, dominating over uptake ...

The livestock sector contributes considerably to global greenhouse gas emissions (GHG). Here, for the year 2007 we examined GHG emissions in the EU27 livestock sector and estimated GHG emissions from production and consumption of livestock products; including imports, exports and wastage. We also reviewed available mitigation options and estimated their potential. The focus of this review is on...

BACKGROUND A comprehensive, HIV prevention programme (Projet Sida1/2/3) was implemented among female sex workers (FSWs) in Cotonou, Benin, in 1993 following which condom use among FSWs increased threefold between 1993 and 2008 while FSW HIV prevalence declined from 53.3% to 30.4%. OBJECTIVE Estimate the potential impact of the intervention on HIV prevalence/incidence in FSWs, clients and the ...

OBJECTIVE In life-cycle assessment, the functional unit defines the unit for calculation of environmental indicators. The objective of the present study was to assess the influence of two functional units, 100 g and 100 kcal (420 kJ), on the associations between three dimensions for identifying sustainable foods, namely environmental impact (via greenhouse gas emissions (GHGE)), nutritional qua...
