Time-course characteristics for the digestion of endogenous as well as exogenous protein in the small intestine: a case study with rats fed a [15N]-soy protein isolate.

چکیده
A study was conducted to evaluate a net value of exogenous (dietary) protein nutrition in rats fed a [15N]-labeled soy protein isolate (SPI). Although [15N]-SPI-derived nitrogen reached a plateau 2 hr after feeding, it accounted for only a half of the total nitrogen in the small intestine. 15N was confirmed that was normally transported to liver, kidney, spleen, and brain. The present study reveals the large degree of participation of endogenous proteins in dietary SPI during small-intestinal digestion.

Rumen Degradability and Model Prediction of Nutrient Supply to Ruminants from Different Processed Soybean Meals
DVE2010 system was used for model prediction of nutrient supply to ruminants from soy bean meal (SBM), extruded soy bean meal (SBE) and full-fat soybean meal (FSBM). Extruded soy bean meal had the highest truly absorbed rumen undegraded protein in the small intestine (ARUP) followed by SBM and FSBM. There was no significant difference between SBE and FSBM in the case of truly absorbed rumen syn...

متن کاملModulation of cellular transport characteristics of the human lung alveolar epithelia
Among the drug delivery and targeting (DDT) routes, lung alveolar epithelium has been given enormous attentions in terms of the delivery of a wide range of macromolecules such as gene- or protein-based nanopharmaceuticals. However, little is known about cellular modulation of lung transport characteristics by endogenous and/or exogenous agents. Thus, in the current study, impact of dexamethason...
