The widespread use of alkylphenols in European industry has led to their presence in the environment and the living organisms of the Baltic Sea. The present study (2011-2012) was designed to determine the concentrations of alkylphenols, 4-nonylphenol (NP) and 4-tert-octylphenol (OP), in surface sediments of the Gulf of Gdansk, a section of the Baltic that lies in close proximity to industrial a...
The rich and diverse microbiota of the rumen provides ruminant animals the capacity to utilize highly fibrous feedstuffs as their energy source, but there is surprisingly little information on the composition of the microbiome of ruminants fed all-forage diets, despite the importance of such agricultural production systems worldwide. In three 28-day periods, three ruminally-cannulated Holstein ...
organophosphorous (op) chemical warfare nerve agents mainly sarin and tabun were used during the iran-iraq war with high mortalities. in addition to atropine and oximes, the followings have recently been used successfully for the treatment of op poisoning. 1. sodium bicarbonate: infusion of high doses of sodium bicarbonate (5 meq/kg in 60 min. followed by 5-6 meq/kg/day to obtain arterial blood...
