The volatile fatty acid profiles were determined by a simple gas chromatographic method in 375 microbiologically positive and negative blood cultures. Aerobic bacteria yielded profiles with low content of acids, some of which were chromatographically negative. Anaerobic bacteria produced more acids and more distinctive profiles. The method makes it possible to confirm the microbiological findin...

A growing body of evidence highlights the relevance of free fatty acids (FFA) for human health, and their role in the cross talk between the metabolic status and immune system. Altered serum FFA profiles are related to several metabolic conditions, although the underlying mechanisms remain unclear. Recent studies have highlighted the link between gut microbiota and host metabolism. However, alt...

Nutrition has a significant effect on reproduction and lactation in Ruminant. Supply of require nutrient of dairy cows and ewes in early lactation is the main challenges that will be considered, since in most cases the animals facing negative energy balance after calving and the beginning of the period of lactation. Negative energy balance may sometimes result in reduced livestock production an...

the ratio of ω-6: ω-3 is connected to the higher risk of non-communicable diseases, thus this ratio is becoming more important than quantity of ω-6 and ω-3 in human nutrition. in countries like iran, cow’s milk is mainly produced in rural area and less in conventional systems. the lactating cows reared in rural and conventional farms are different in terms of nutrition, daily yields, and propor...

This study evaluated the effects of season and spatial distribution on the fatty acid composition of Patella depressa gonads and Patella spp. soft body tissue. The results show that the quantitatively most important fatty acids were the saturated fatty acids (SFA) 16:0, 14:0 and 18:0; the monounsaturated fatty acids (MUFA) 18:1(n-7), 18:1(n-9), 16:1(n-7) and 20:1(n-9) and the polyunsaturated fa...

   Two omega-3 fatty acids including docosahexaenoic acid (DHA) and eicosapentaenoic acid (EPA) are essential for the physiologic function of neuronal cell membrane. Normal function of neuronal cell membrane requires appropriate composition of fatty in its structure. Present study was designed to compare the effect of short-term and long-term pretreatment with omega-3 fatty acids on scopolamine...

Fatty acids are important in human health and useful in the analysis of the marine food web, however information on tropical pelagic organisms is scarce. Six zooplanktivorous small pelagic fish species (Decapterus kurroides, Decapterus macarellus, Selar crumenophthalmus, Sardinella lemuru, Spratilloides gracilis and Stolephorus insularis) and four of their zooplanktonic crustacean prey [three s...

milk and dairy products are in diet almost every day. milk fat contains 70% of saturated fatty acids which can cause an increase in total and low-density lipoprotein cholesterol, and the risk of cardiovascular diseases. therefor, modification of fat composition at dairy products such as yoghurt seems necessary. walnut has high amount of essential fatty acids, anti oxidants and other beneficial ...

modifications in fat and fatty acid composition of silver carp that take place at each stage of canning process (precooking and sterilization) were evaluated. results showed, precooking led to decrease total fat and increase conjugated dines. the amounts of free fatty acids and thiobarbituric acids had no changed during precooking but these compounds like conjugated dine were increased after st...
