(13) Considerable glucose 6-phosphatase activity survived 240min of treatment with phospholipase C at 5 degrees C, but in the absence of substrate or at physiological glucose 6-phosphate concentrations the delipidated enzyme was completely inactivated within 10min at 37 degrees C. However, 80mM-glucose 6-phosphate stabilized it and phospholipid dispersions substantially restored thermal stability.
(14) These results are consistent with a possible physiological role for medullary TRH in the vagal regulation of gastric contractility.
(15) The cells were taken from cultures in low-density balanced exponential growth, and the experiments were performed quickly so that the bacteria were in a uniform physiological state at the time of measurement.
(16) Atrioventricular (AV) delay that results in maximum ventricular filling and physiological mechanisms that govern dependence of filling on timing of atrial systole were studied by combining computer experiments with experiments in the anesthetized dog instrumented to measure phasic mitral flow.
(17) At physiologic doses (10(-8) M) estradiol inhibits the binding at a significant extent on the soluble receptor, but not on membrane-bound form.
(18) With the successful culture of these tissues, their development, biochemistry, and physiology, potentially of great importance in understanding early vertebrate evolution, can be better understood.
(19) The binding follows the principle of isotope dilution in the physiologic range of vitamin B12 present in human serum.
(20) Axonal regeneration with the ANG was equal to SAGs as measured by axonal diameters, physiological, and functional methods, although the SAG demonstrated statistically higher axonal counts.
Sphincter
Definition:
(n.) A muscle which surrounds, and by its contraction tends to close, a natural opening; as, the sphincter of the bladder.
(a.) Of, pertaining to, or designating, a sphincter; as, a sphincter muscle.
Example Sentences:
(1) We suggest that neuronal PACAP may serve to modulate motor activity and secretion in the lower esophageal sphincter region.
(2) Although it is known that the sphincter of Oddi exhibits a myoelectric response to intraluminal nutrients, the effect of specific dietary components has not been well characterized.
(3) Fourteen patients were examined one to four years after cricopharyngeal myotomy that had been carried out because of dysfunction of the pharyngo-esophageal sphincter.
(4) The paper postulates that 'anal or sphincter defensiveness' is one of the precursors of the repression barrier.
(5) In 36 patients plastic reconstruction of the urinary bladder, sphincter and urethra was performed with local tissues after the Young technic in the G. A. Bairov modification.
(6) 12 children (38%) showed modifications of bladder-sphincter equilibrium, without acquiring socially sufficient continence.
(7) We found that in the patient's view an adequate result requires establishment of a proper lip sphincter--either by restoring muscular tone, or by creating an anatomical framework to which can be added either a motor unit or stabilization to aid the opposite intact muscle.
(8) Extensive drainage procedures were avoided to preserve the anal sphincter.
(9) Changes in pupil size indicated a substantial cholinergic effect on the iridal sphincter musculature.
(10) The dumping-syndrome is a severe complication of gastric surgery after operations which destroy or weaken the sphincter mechanism of the pylorus.
(11) This appears to be caused by persistent reflux of gastric juice across a mechanically defective lower esophageal sphincter.

(15) Multiple factors contribute to the production of esophagitis in gastroesophageal reflux (GER), but the respective roles of esophageal (i. e. lower esophageal sphincter (LES) tone, peristalsis) and gastric factors (i. e. acid secretion and gastric emptying) are not well known.
(16) Pyloric sphincter pressure was assessed with water-perfused polyvinyl tubes.
(17) The frequent occurrence of delayed drainage in these asymptomatic post-cholecystectomy volunteers challenges the validity of the 45-min delayed drainage criterion for sphincter of Oddi dysfunction.
