Abstract The gastrointestinal tract exists to support nutrition, digesting and assimilating nutrients including water and salts. Disorders of the gut readily impair nutritional status, although there is considerable functional reserve. Many macronutrients are structural components of animals and plants, and therefore ingested in complex molecular ...

Absorption sampling and the absorption distribution
Journal of Applied Probability, 1998The inverse absorption distribution is shown to be aq-Pascal analogue of the Kemp and Kemp (1991)q-binomial distribution. The probabilities for the direct absorption distribution are obtained via the inverse absorption probabilities and exact expressions for its first two factorial moments are derived usingq-series transformations of its probability ...

Current Opinion in Gastroenterology, 2001
Many advances in the study of nutrient absorption have been made with the use of molecular and genetic techniques; however, standard in vivo studies have provided interesting and important new information. Omega-3 long-chain fatty acids have unexpected effects on lipoprotein formation and secretion in neonatal intestinal cells; this needs to be ...

Publisher Summary This chapter focuses on pesticide absorption with an expanded focus on dermal absorption as workers involved in pesticide manufacturing, formulation, or application and harvesting of treated crops are more likely to be exposed to these chemicals via the skin. Absorption is the translocation of the pesticide from an external source of

Abstract The absorptive pattern of a series of peptides has been investigated with an in vitro sac preparation from rat intestine. Results demonstrate a specificity of hydrolysis and ability to traverse the intestinal wall. The mechanism is discussed whereby accumulation of intact peptide may occur in the serosal solution.

Absorption takes place when a compound enters an organism, which occurs as soon as the molecules enter the first cellular bilayer(s) in the tissue(s) to which is it exposed. At that point, the compound is no longer part of the environment (which includes the alimentary canal for oral exposure), but has become part of the organism.

Material in the review on light absorption spectrometry is classified as chemistry, physics, and applications. Separate tables are given for photometric methods for metals, nonmetals, and organic compounds. 535 references are given to reports, patents, and U. S. and foreign journals and books published from September 1959 to October 1961.

Absorption of Chlorhydroxyquinoline
Nature, 1963THERE has been some uncertainty about the fate of halogenated derivatives of oxine in the body1, but only a small part of an oral dose of Chlorhydroxyquinoline could be detected in the urines of rats1,2. In further experiments, traces were found in the blood of rats but the amount could not be estimated.

Abstract.It is desirable to improve metabolic control in diabetics receiving insulin. Studies on insulin kinetics provide information that may be useful in the optimization of the injection scheme. Absorption has been measured using 1251‐insulin as marker and counting the residual activity with a crystal detector.
