Radioiodinated protein solutions, 20 nl in volume, were injected into surface proximal and distal convoluted tubules of the rat kidney. The unabsorbed fraction was collected in ureteral urine, and the percentage recovered was expressed as a function of the injection site. Recovery increased progressively from more distal sites of injection indicating absorption along the proximal tubule of huma...

Each major phase in the evolution of our present concept of the absorption of proteins and their digestion products has been initiated by an improvement in analytical techniques or experimental methods. Before 1900, it was thought that the final products of protein digestion were proteoses and peptones, and it seemed likely that proteins were absorbed in these forms. Then Cohnheim (1901) discov...

the delivery of therapeutic proteins has gained momentum with development of biotechnology. however, large molecular weight, hydrophilic nature and susceptibility to harsh environment of gastrointestinal tract (git) resulted in low absorption. the main objective of this work was the design of a particulate system for oral delivery of recombinant human growth hormone (rhgh) on the basis of parti...

The small intestine acts as interface and regulator between the gut lumen and the rest of the body and controls the degree and rate of transport of amino acids coming from dietary protein via the portal vein to the liver and the systemic circulation. To measure protein absorption, kinetics multicatheter animal (pig) models in combination with amino acid tracer technology are available. Dietary ...

The aim of this research was to determine existence the correlation between chemical and certain rheological quality parameters different wheat flour samples bread produced from them. Three type 500, which were as experimental in industrial conditions, analyzed. analysis composition (content water, ash, ash on dry matter, fat, protein, starch) farinograph (farinograph water absorption, dough de...
