Strong activity of the TGF mechanism was also indicated by a large proximal-distal difference in the single-nephron glomerular filtration rate (11.9 nl/min versus 3.3 nl/min in sham-operated controls) in the hydronephrotic kidney during volume expansion. Thus, in hydronephrotic kidneys in the ...
Analysis of the data using mathematical models, presented here by Ramit Meher and colleagues, suggests possible feedback control mechanism in T-cell development.关键词: Animals Mice T-Lymphocytes Lymphocyte Activation Cell Division Major Histocompatibility Complex Models, Immunological Feedback Thymus Gland...
Scientists are actively investigating the feedback mechanism within the physical, chemical, and biological components of Earths climate system in order to make accurate predictions of the effects the rise in greenhouse gases will have on future global climates. Global circulation models are important too...
In these animals a chronic gastric fistula was made so gastric secretion could also be collected. Diversion-replacement of pure pancreatic juice and of bile were carried out in the fasting state. This study confirms the presence of a feedback regulatory mechanism in exocrine pancreatic secretion in...

fact that ovariectomy had no effect on SME and plasma FSH-RF, and that the pituitary gland must subsequently be removed to effect a change in FSH-RF activity, strengthens the concept that the hypophysis, by itself, can exert a profound influence on the hypothalamic FSH-RF secretory mechanism....
This provides additional insight into the cellular mechanism by which gonadal hormones determine central sensitivity to leptin, and may help elucidate the long-noted sex differences in leptin sensitivity. Additionally, we observed that Tyr985 signaling protects against a diet-dependent switch that ...
These results indicate that the mechanism underlying surround inhibition of AII amacrine cells includes activation of both GABA A and GABA C receptors in an approximately equal ratio. Application of the GABA antagonists also increased the size of on-centre receptive fields of AII amacrine cells. ...
The current study investigated whether contralateral afferent feedback contributes to the mechanism controlling the SLCR in human gastrocnemius muscle. Surface electromyogram, kinematic and kinetic data were recorded from subjects during normal walking and hybrid walking (with the legs moving in opposite ...
