• Transport
  • 1. The intestinal transport of oligopeptides containing either lysine or arginine has been compared with that of the corresponding free amino acids in six homozygous cystinuric patients and in six normal adult subjects by use of the oral tolerance test technique. (clinsci.org)
  • Our study suggests the participation in CH3Hg absorption of transporters that have already been identified as being responsible for the transport of this species in other systems, although further studies are needed to confirm their participation in intestinal absorption. (mysciencework.com)
  • Extensive clinical studies established that HFM is due to (i) impaired intestinal absorption of folates and (ii) impaired transport of folates across the blood-choroid plexus-cerebrospinal fluid (CSF) barrier. (wikipedia.org)
  • evaluate
  • The purpose of this study was to evaluate intestinal absorption, organ distribution, and urinary elimination of the rare sugar D-psicose, a 3-carbon stereoisomer of D-fructose that is currently being investigated and which has been found to be strongly effective against hyperglycemia and hyperlipidemia.

  • mechanisms
  • Although the diet is known to be the main source of exposure, few studies have characterized the mechanisms involved in the absorption of this contaminant. (mysciencework.com)
  • Bile
  • Hyodeoxycholic acid, also known as 3α,6α-Dihydroxy-5β-cholan-24-oic acid or HDCA, is a secondary bile acid, one of the metabolic byproducts of intestinal bacteria. (wikipedia.org)
  • flux
  • Cotransport was the first ever proposal of flux coupling in biology and was the most important event concerning carbohydrate absorption in the 20th century. (wikipedia.org)
  • diffusion
  • The results showed that the intestinal absorption of rhein occurred through active diffusion, and rhein might be composed of breast cancer resistance protein (BCRP) substrates. (hindawi.com)
  • Reid invented a recording osmometer, and at Dundee investigated secretion and absorption and the processes of diffusion, osmosis and filtration in the passage of materials across surfaces. (wikipedia.org)
  • properties
  • However, the intestinal absorption properties of major ingredients of most herbal medicines are unknown, probably because of lack of sensitive analytical methods, difficulties in choice of the marker ingredients, and other confounding factors. (aspetjournals.org)
  • rates
  • 5. Absorption rates of the dipeptides l-lysylglycine and l-arginyl-l-aspartate from an isolated loop of rat gut are compared with those of an equivalent free amino acid mixture. (clinsci.org)
  • No difference was found for the former peptide, but in the latter absorption rates of arginine were higher after the amino acid mixture. (clinsci.org)
  • present
  • With longer absorption periods, frequent grains are present over accumulations of fat droplets in the Golgi cisternae and intercellular spaces. (rupress.org)
  • patients
  • In patients who had undergone ileal resection the absorption of both phosphatidylcholine and triglyceride was subnormal, as reflected by a lower production of 14CO2. (semanticscholar.org)
