In the gut, retinoic acid induces expression of the integrin α4β7and C–C motif chemokine receptor (CCR)9 in the small intestine and CCR10 in the colon. Expression of α4β7 and, either CCR9 or CCR10, give the lymphocyte a gut-homing phenotype. The ligand for α4β7 is the ...
Amplitudes of molecular optical events are proportional to off-diagonal matrix elements of interaction operators between the wavefunctions of the initial, final, and possibly also intermediate states of the molecule, |0〉, |f〉, and |j〉 respectively. These operators are projections of molecular tra...
What are the five basic functions of the digestive system? What are the main organs in the digestive system and what are the functions of each? Mammals exhibit a double circulatory system. Describe how blood circulates in the mammalian heart. ...
Upon microbial fermentation of dietary fibers, the intestinal microbiota produces short chain fatty acids (SCFAs) which are fatty acids with fewer than six carbon atoms2,3. The total concentration of SCFAs in the intestinal tract ranges from ~ 11 to 13 mM in the distal small intestine to...
Extracellular vesicles (EVs) are lipid vesicles secreted by cells, and the protein, nucleic acid and lipid components carried on the surface and inside can be delivered to recipient cells and regulate their functions [174]. As one of the main channels of intercellular communication, EVs play a ...

anything.So,even though she showed no signs of cancer at all,Fisher,51,a former mental health worker,agreed to undergo what might sound like a radical surgery:doctors removed nearly her whole colon(结肠) and rerouted her small intestine(肠) to perform the functions of her large intestine. ...
Release from adipocytes in the small intestine Key role in energy metabolism Fat accumulation in human body before the onset of T2DM promotes In insulin resistance in T2DM and obesity, a decreased sensitivity to leptin occurs Leptin deficiency leads to obesity, excess levels of circulating insulin, ...
Embryogenesis also involves early programming within tissues that will determine functions and behavior throughout life. These changes are progressive, being modulated by the needs of both the mother and the growing fetus. An important number of hormones, neuropeptides and growth factors are involved ...
