The aim of this work was to investigate the effect of feeding ethyl-3-nitrooxy propionate (E3NP) and 3-nitrooxypropanol (3 NP), 2 recently developed compounds with potential antimethanogenic activity, in vitro and in vivo in nonlactating sheep on ruminal methane production, fermentation pattern, the abundance of major microbial groups, and feed degradability. Three experiments were conducted, 1...

this experiment was conducted using 172 male lambs of ghezel and mehraban breeds for two periods of 60 and 80 days. two systems of fattening were studied. the first group of lambs entered feedlot boxes immediately after weaning (spring) but the second group being fed on pasture, entered the experiment approximately 4 months later (autumn). fattening periods were 60 and 80 days. the average wean...

Two endpoints of genetic toxicity, mutation at the X-linked Pig-a gene and chromosomal damage in the form of micronucleated reticulocytes (MN-RETs), were evaluated in blood samples obtained from 28-day repeat-dosing studies typical of those employed in toxicity evaluations. Male Wistar Han rats were treated at 24-h intervals on days 1 through 28 with one of five prototypical genotoxicants: N-et...

Egg production of cultivated broodstocks of orange-spotted grouper, Epinephelus coioides and larvae rearing were surveyed in Iran from 2008 to 2012. . Broodstocks were obtained by rearing of 7 wild juveniles (587.57 ± 132.63 g body weight) which were caught from the north of Persian Gulf in October 2008 and reared to December 2012.. Captured juvenile fishes were fed using defrosted trash fish a...

Since a report by Spyker et al.,1) a number of studies have shown various behavioral changes after perinatal exposure to methylmercury in open field tests,2) shock avoidance learning') and operant learning.4) Taste aversion learning is considered a useful examination in behavioral teratology.5) It requires no special behavioral equipments and seems to be less affected by motor dysfunction than ...

OBJECTIVE To determine the effects of intravenous N-acetylcysteine (NAC) on the development of severe adult respiratory distress syndrome (ARDS) and mortality rate in patients with mild-to-moderate acute lung injury and to analyze the duration of ventilatory support and FIO2 required as well as the evolution of the lung injury score. SETTING Three university hospital ICUs and one regional ICU...

Eleven healthy girls (mean(SD): age 12.1(0.6) years) completed three, 2-day conditions in a counterbalanced, crossover design. On day 1, participants either walked at 60(2)% peak oxygen uptake (energy deficit 1.55(0.20) MJ) (EX), restricted food energy intake (energy deficit 1.51(0.25) MJ) (ER) or rested (CON). On day 2, capillary blood samples were taken at pre-determined intervals throughout ...

Folate deficiency associated with low dietary intake is a well-documented public health problem, resulting in serious health and socioeconomic burdens. Therefore, optimization of the germination process of different cultivars of legume seeds in relation to the content and composition of folate, vitamin C, and total phenolics and total antioxidant capacity was carried out to maximize the health-...
