Malakooti, Jaleh, Refka Y. Dahdal, Larry Schmidt, Thomas J. Layden, Pradeep K. Dudeja, and Krishnamurthy Ramaswamy. 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...

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...

Ouellette, Andre J. Mucosal Immunity and Inflammation. IV. Paneth cell antimicrobial peptides and the biology of the mucosal barrier. Am. J. Physiol. 277 (Gastrointest. Liver Physiol. 40): G257–G261, 1999.—The hypothesis that epithelial cells release preformed antibiotic peptides as components of mucosal innate immunity has gained experimental support in recent years. In the mammalian small int...

Ihlemann, Jacob, Thorkil Ploug, Ylva Hellsten, and Henrik Galbo. Effect of tension on contraction-induced glucose transport in rat skeletal muscle. Am. J. Physiol. 277 (Endocrinol. Metab. 40): E208–E214, 1999.—We questioned the general view that contraction-induced muscle glucose transport only depends on stimulation frequency and not on workload. Incubated soleus muscles were electrically stim...

Radziuk, Jerry, and W.-N. Paul Lee. Measurement of gluconeogenesis and mass isotopomer analysis based on [U-13C]glucose. Am. J. Physiol. 277 (Endocrinol. Metab. 40): E199–E207, 1999.—Two methods of measuring rates of gluconeogenesis based on label redistribution after the introduction of [U-13C]glucose into the whole body are examined. These methods are compared with methods previously derived ...

Roberts, Christian K., R. James Barnard, Arnie Jasman, and Thomas W. Balon. Acute exercise increases nitric oxide synthase activity in skeletal muscle. Am. J. Physiol. 277 (Endocrinol. Metab. 40): E390–E394, 1999.—This study examined the effects of acute exercise on skeletal muscle nitric oxide synthase (NOS) activity. Female Sprague-Dawley rats were divided into three groups: control, exercise...

Horowitz, Jeffrey F., Renata J. Braudy, Wade H. Martin III, and Samuel Klein. Endurance exercise training does not alter lipolytic or adipose tissue blood flow sensitivity to epinephrine. Am. J. Physiol. 277 (Endocrinol. Metab. 40): E325–E331, 1999.—We evaluated the relationship between lipolysis and adipose tissue blood flow (ATBF) in response to epinephrine and the effect of endurance exercis...

Preiksaitis, Harold G., and Nicholas E. Diamant. Myogenic mechanism for peristalsis in the cat esophagus. Am. J. Physiol. 277 (Gastrointest. Liver Physiol. 40): G306– G313, 1999.—A myogenic control system (MCS) is a fundamental determinant of peristalsis in the stomach, small bowel, and colon. In the esophagus, attention has focused on neuronal control, the potential for a MCS receiving less at...
