Corleto, Vito D., H. Christian Weber, and Robert T. Jensen. Expression of somatostatin receptor subtypes on guinea pig gastric and colonic smooth muscle cells. Am. J. Physiol. 277 (Gastrointest. Liver Physiol. 40): G235–G244, 1999.—In vivo and in vitro studies have demonstrated that somatostatin can influence motility and smooth muscle contractility of the stomach and colon. Recent studies have...

Parolin, Michelle L., Alan Chesley, Mark P. Matsos, Lawrence L. Spriet, Norman L. Jones, and George J. F. Heigenhauser. Regulation of skeletal muscle glycogen phosphorylase and PDH during maximal intermittent exercise. Am. J. Physiol. 277 (Endocrinol. Metab. 40): E890–E900, 1999.—The time course for the activation of glycogen phosphorylase (Phos) and pyruvate dehydrogenase (PDH) and their allos...

Both alcohol use and stress appear to increase blood pressure. In addition, stress is associated with increased alcohol use. To investigate these relationships, researchers interviewed representative samples of the black and non-black adult household populations in Erie County, New York, in 1986, 1989, and 1993. The results support a causal relationship between stress and alcohol use and point ...

Previs, Stephen F., Gary W. Cline, and Gerald I. Shulman. A critical evaluation of mass isotopomer distribution analysis of gluconeogenesis in vivo. Am. J. Physiol. 277 (Endocrinol. Metab. 40): E154–E160, 1999.—There are conflicting reports concerning the reliability of mass isotopomer distribution analysis (MIDA) for estimating the contribution of gluconeogenesis to total glucose production (f...

Molecular cloning, tissue distribution, and functional expression of the human Na1/H1 exchanger NHE2. Am. J. Physiol. 277 (Gastrointest. Liver Physiol. 40): G383–G390, 1999.—In the present report, we describe the cloning of a human colonic cDNA that describes the full-length Na1/H...

Carlson, Scott H., and J. Michael Wyss. Hepatic denervation does not affect plasma vasopressin response to intragastric hypertonic saline in conscious rats. Am. J. Physiol. 277 (Endocrinol. Metab. 40): E161–E167, 1999.—Peripheral osmoreceptors monitor dietary NaCl and modify central nervous system and renal sympathetic nervous system activity accordingly. Experimental evidence suggests that the...

Mizuta, Yohei, Toku Takahashi, and Chung Owyang. Nitrergic regulation of colonic transit in rats. Am. J. Physiol. 277 (Gastrointest. Liver Physiol. 40): G275–G279, 1999.— Nitric oxide has been shown to be an inhibitory neurotransmitter in the mammalian colon, although its role in colonic transit remains unclear. We investigated the effect of the nitric oxide biosynthesis inhibitor NG-nitro-L-ar...

Xu, Chuanli, Yanjie Lu, Guanghua Tang, and Rui Wang. Expression of voltage-dependent K1 channel genes in mesenteric artery smooth muscle cells. Am. J. Physiol. 277 (Gastrointest. Liver Physiol. 40): G1055–G1063, 1999.— Molecular basis of native voltage-dependent K1 (Kv) channels in smooth muscle cells (SMCs) from rat mesenteric arteries was investigated. The whole cell patch-clamp study reveale...
