It has recently been suggested that HCV genotype 2 (HCV-2) was more recently introduced to Cameroon (Middle Africa) than West African countries. In order to explore the relationships among HCV-2 strains from Cameroon and West Africa, and to estimate the epidemic history of each lineage, a recently-developed Bayesian evolutionary analysis approach was used. The estimated date of the most recent ...

a faunestic survey of the euoribatid mites of shendabad region (east azerbaijan province, iran), was carried out during three different times of the year 2008 (mid-july, mid-august as well as mid-september). by use of the berlese funnel, the mites were extracted, cleared in nesbitt’s fluid following which microscopic slides were prepared. during the study, 31 species belonging to 21 genera, 13 ...

Purpose: The present research evaluated the effect of using a back brace for 8 weeks on the Electromyography (EMG) activity of the selected muscles among individuals with chronic back pain in the mid-stance phase of walking. Methods: This quasi-experimental research evaluated 22 women with chronic back pain in terms of erector spinae muscles activity, abdominal erectus, abdominal external obli...

the short and long term effects of chromium toxicity on brain catecholamines and acetylcholinesterase levels were investigated. rats were injected daily with varying amounts of chromium. the short term (2 h) administration of chromium (8 mmol/kg) reduced catecholamines level of cerebellum, mid-brain and brain-cortex by 22.8, 19.4 and 21.2% respectively. acetylcholinesterase activity was also re...

Catecholamine is a group of neurotransmitters that is believed to be responsible for the normal function of animal brain. Physiological and behavioral changes of human body have been reported due to the damage of the brain function following lead exposure. Due to the assumption of lead disposal in brain tissue with two year for its half-life, which results in alteration of brain function, we in...

birth weight is an important indicator of child survival. appropriate and timely care of a newborn specially if he or she is born with low birth weight is important but this is difficult in developing countries since most of the deliveries are conducted at home where adequate facilities to weight a new born does not exist. this study was conducted to find out a surrogate which could efficiently...

Our objective was to determine whether data from a previous study using model milk emulsions to characterize the influence of variation in fatty acid chain length and unsaturation on mid-infrared (MIR) fat predictions could be used to identify a strategy to improve the accuracy of MIR fat predictions on a population of farm milks with a wide variation in fatty acid chain length and unsaturation...

Fatty acid composition influences the nutritional quality of milk and the technological properties of butter. Using a prediction of fatty acid (FA) contents by mid-infrared (MIR) spectrometry, a large amount of data concerning the FA profile in bovine milk was collected. The large number of records permitted consideration of more complex models than those used in previous studies. The aim of th...
