متن کاملCOMPARATIVE GUT PHYSIOLOGY SYMPOSIUM: Comparative physiology of digestion.
The digestive systems of all species have been shaped by environmental pressures over long evolutionary time spans. Nevertheless, all digestive systems must achieve the same end points, the ingestion of biological material and its conversion to molecules that serve as energy substrates and structural components of tissues. A range of strategies to extract nutrients, including for animals relian...
متن کاملPrinciples of Physiology of Lipid Digestion
The processing of dietary lipids can be distinguished in several sequential steps, including their emulsification, hydrolysis and micellization, before they are absorbed by the enterocytes. Emulsification of lipids starts in the stomach and is mediated by physical forces and favoured by the partial lipolysis of the dietary lipids due to the activity of gastric lipase. The process of lipid diges...

sue samples using Proteinase K digestion method. A 5 ug of the viral RNA was used for the synthesis of cDNA using RevertAid TM First Strand cDNA Synthesis Kit (MBI, Fermentas). The VP2 hypervariable region of the IBDV was amplified using specific primers. A single band of PCR product of the expected size was visualized on 1.5% agarose gel after ethidium bromide staining. Results indicated that ...
