Gastric lipase (GL) plays an important role in emulsification and digestion of food fat. Lipids are components of the hydrophobic mucus and mucosa barrier. Damage of the gastric mucosa may therefore be related to changes in the lipid content and GL activity. In the present paper, we studied the effect of administration of a single dose of 96 % ethanol (E) and indomethacin 20 mg x kg(-1) (IND) o...

The objective of this study was to determine the pattern of nutrient flux across portal-drained viscera (PDV) and liver in ewes with varying numbers of fetuses. Catheters were placed in the hepatic portal vein, a branch of the hepatic vein, a mesenteric vein, and the abdominal aorta of each ewe. Plasma flow and net cholesterol, nonesterified fatty acids (NEFA), and glycerol release across the P...

Milk synthesis being a continuous process in lactating sows, the mammary gland has to adapt its metabolism response extreme short-term changes nutrient availability arterial bloodstream, due feeding pattern. The objective of present study was better quantify and understand these adaptations. effect morning refeeding after an overnight 16-h feed withdrawal measured on uptake energy-supplying nut...

background a fall in plasma concentration of energy status related hormones (leptin, insulin-like growth factor-1 (igf-1) and insulin) and body energy expenditure occurs in response to short term fasting. nevertheless, the relations of the fasting-induced changes in energy related hormones and metabolites with fasting energy expenditure (fee) under extended fasting condition have received littl...

Background: It was hypothesized that under apparently good management practices in dairy farms, some cows may not be metabolically perfect during the breeding period and this may affect their performance. Aims: This study was conducted to assess probable metabolic drawbacks in mid-lactation dairy cows affecting their performance. Methods: Thirt...

UICKI is an index of insulin sensitivity based on the determination of glucose and insulin concentrations in the postabsorptive state [1]. It has been shown to be well correlated with insulin sensitivity across the entire spectum of glucose tolerance, but its performance is less satisfactory in normal subjects [1]. To overcome this drawback, QUICKI has been subsequently revised with the incorpo...

Many autoantibodies associated with nucleic acids are found in autoimmune diseases, and are important for analyzing pathophysiologic mechanisms. Toll-like receptors (TLRs) are receptor molecules for innate immunity and some of them recognize nucleic acids. Nucleic acids in autoantigens may stimulate TLR and activate antigen presenting cells as adjuvants. The Wa antigen was found as a transfer R...
