ALBERT, ~VILLIAM C., AND JOSEPH S. HANDLER. EJect of PGEl, indomethacin, and fo&hloretin phosphate on toad bladder response to ADH Am. J. Physiol, 226(6) : 1382-l 386. 1974.-Exogenous PGEr inhibits the short-circuit current response, as well as the water permeability response of the toad bladder to vasopressin. Since PGEI does not inhibit either response to cyclic AMP, it is thought to act by i...

The role of cyclic AMP in the regulation of aldosterone production by adrenocorticotropic hormone (ACTH), angiotensin II (A II), potassium, and serotonin was examined in collagenase-dispersed adrenal glomerulosa cells. The ability of 8-bromo cyclic AMP and choleragen to stimulate maximum aldosterone production indicated that cyclic AMP could act as second messenger for certain of the aldosteron...

Various prostaglandins (PGs) have been found in several areas of the brain. PGs of the E series have been found in the pituitary and pineal glands and the median eminence, and they have been shown to influence hypothalamic endocrine-release characteristics and release of melatonin from the pineal gland. It has been suggested that they may act, along with membrane phospholipids, as a link betwee...

Long–term stability and oxidation resistance of AISI 439 ferritic stainless steel used as interconnects in solid oxide fuel cells can be improved by use of a protective coating. In this study the pack cementation method was employed to coat AISI 439 ferritic stainless steel with manganese. Isothermal oxidation was conducted at 800 ºC for 200 hours in static air to investigate the role of coatin...

On the basis of the information presented in this review, it is difficult to reach any firm decision regarding the role of cyclic AMP (or cyclic GMP) in synaptic transmission in the brain. While it is clear that cyclic nucleotide levels can be altered by the exposure of neural tissues to various neurotransmitters, it would be premature to claim that these nucleotides are, or are not, essential ...

Cyclic adenosine 3’,5’-monophosphate (cyclic AMP) increases the differential rate of synthesis of @-galactosidase in Escherichia coli made permeable by treatment with t&(hydroxymethyl)aminomethane and ethylenediaminetetraacetic acid. In normal, growing cells, cyclic AMP overcomes the transient repression of /3-galactosidase by glucose. A half-maximal effect of cyclic AMP occurs at about 7 x 10-...

in this study, a researching program is conducted by cyclic triaxial test to determine the post-cyclic behavior of bushehr carbonate sand retrieved from the north of the persian gulf, under anisotropic consolidation at 200 kpa confining pressure. the article compares the post-cyclic monotonic strength and excess pore water pressures generated after the test with the pre-cyclic monotonic results...

abstract: this paper presents the results of pullout tests on uniaxial geogrid embedded in silica sand under monotonic and cyclic pullout forces. the new testing device as a recently developed automated pullout test device for soil-geogrid strength and deformation behavior investigation is capable of applying load/displacement controlled monotonic/cyclic forces at different rates/frequencies an...
