The vasodilator response of nitric oxide (NO), hydrogen sulfide (H2S) and sulfur dioxide (SO2) were studied todetermine the significance of the actions and interactions of these gasotransmitters for controlling aortic tone in rats. The isometric tension of five separate sets of experiments was recorded. Sodium nitroprusside (SNP; NO donor), sodium disulphide (Na2S; H2S donor), SO2 derivatives a...

Over the past decade, the relationship between IT and performance has been one of the most actively researched topics in MIS. Since Robert Solow quipped that “You can see the computer age everywhere but in the productivity statistics,” over 50 empirical studies have investigated IT’s impacts on productivity and performance. These studies have been motivated by the economic paradox implicit in S...

We used the euglycemic clamp to assess the effects of exercise on maximally insulin-stimulated glucose disposal. In 11 young men, a 60-min bout of exercise had no significant effect on the rate of glucose disposal during a euglycemic clamp performed approximately 30 min postexercise in which plasma insulin was raised to approximately 2,500 microU/ml (a maximal insulin stimulus). The maximal rat...

background numerous studies were carried out to develop more sophisticated dressings to expedite healing processes and diminish the bacterial burden in burn wounds. this study assessed the healing effect of nettle extract on second degree burns wound in rats in comparison with silver sulfadiazine and vaseline. methods forty rats were randomly assigned to four equal groups. a deep second-degree ...

has been renamed “Update,” as some users expressed concern over the word “Duplicate.” With these changes in mind, we would like to emphasize that the ultimate purpose of the Déjà Vu database is to maintain the integrity of biomedical literature, a goal that can be achieved only by a thorough and accurate interpretation of the information contained within. We therefore extend to both the editors...

Secretion of gastric acid in response to histamine, insulin, and a meal of liver, with and without 5% bone dust, was studied in three dogs with Pavlov pouches and gastric fistulas. The ratios of insulin-induced to histamine-induced secretion were the same in pouch and main stomach indicating that their innervation was equivalent. Meals of a liver and bone dust mixture in amounts of 11 to 44 g/k...

The effects of chronic dynamic exercise on myocardial /3-adrenergic and muscarinlc cholinergic receptors and chronotropic sensitivity to isoproterenol were studied in 5 Yucatan miniswine. Right atrial and left ventricular biopsies, heart rate responses to isoproterenol, and maximal exercise treadmill testing were obtained before and after 10-19 weeks of treadmill running. Radioligand studies us...
