The difference between the disease rates of two groups, one exposed and one not exposed to a suspected aetiological factor, is a useful measure of the risk associated with the factor. This measure is of most interest when the association is considered causal, and has been termed the attributable risk (MacMahon and Pugh, 1970). Expressed as a percentage of the total disease rate in a group (the ...

the influence of aluminum on some serum parameters related to bone metabolism has been investigated by daily administration of aluminum over different periods of time. daily administration of aluminum (1 mg/kg bw) for 20 or 50 days elevated serum phosphorous concentration by 16 percent and had no significant effect on serum calcium level. when aluminum was injected as a complex with citric acid...

Food yeast, which may be produced from wood carbohydrates and inorganic salts, is a source of protein, fats, and vitamins. The yeast contains about 50 percent of protein and 2 to 7 percent of fat, and is produced in yields of 40 to 50 percent of the carbohydrate from which it is grown. This yield represents a conversion factor of carbohydrates to protein of 4 or 5 to 1, as compared with a ratio...

Brahman cows were used to evaluate the effects of postpartum nutrition and suckling on reproductive and calf performance. Cows received high or low TDN and once-daily or unrestricted suckling. High TDN (H; 111% of NRC recommendation) cows received a 75% corn: 25% soybean meal diet. Low TDN (L; 93% of NRC recommendation) cows received no concentrates. Once-daily suckled (restricted, R) cows nurs...

in order to evaluate the effect of water deficit and different fertilizer levels on yield and some agro-morphological characteristics of moldavian balm, a split plot experiment was conducted in a randomized complete block design with three replications at the research farm of shahrekord university during 2013-2014 growing season. main factor was three levels of irrigation regimes including: 100...

Several dietary oils have been used preventatively and therapeutically in the setting of neurological disease. However, the mechanisms underlying their influence on brain function and metabolism remain unknown. It was investigated whether 3 types of dietary oils affected emotional behaviors in mice. Wild-type (WT) mice and sialyltransferase ST3Gal IV-knockout (KO) mice, which exhibit increased ...

Leptin produced by adipocytes controls body weight by restraining food intake and enhancing energy expenditure at the hypothalamic level. The diet-induced increase in fat mass is associated with the presence of elevated circulating leptin levels, suggesting the development of resistance to its anorectic effect. Rats, like humans, show different susceptibility to diet-induced obesity. The aim of...
