We present recent results on the structure of one-valence-particle $^{41}$Ca and $^{49}$Ca, one-valence-hole $^{47}$Ca, nuclei. The isotopes interest were populated via cold-neutron capture reactions $^{40}$Ca(n,$\gamma$), $^{48}$Ca(n,$\gamma$) $^{46}$Ca(n,$\gamma$), respectively. experiments performed at Institut Laue-Langevin, within EXILL campaign, which employed a large array HPGe detectors...
AIM The aim of this study was to interpret and validate a French version of the Oswestry disability index (ODI), using a cross-cultural validation method. The validity and reliability of the questionnaire was assessed in order to ensure the psychometric characteristics. METHOD The cross-cultural validation was carried out according to Beaton's methodology. The study was conducted with 41 pati...
Mundinger, Thomas O., and Gerald J. Taborsky, Jr. Differential action of hepatic sympathetic neuropeptides: metabolic action of galanin, vascular action of NPY. Am. J. Physiol. Endocrinol. Metab. 278: E390–E397, 2000.—Activation of hepatic nerves increases both hepatic glucose production (HGP) and hepatic arterial vasoconstriction, the latter best described by a decrease of hepatic arterial con...
Ma, L., W. P. Wang, J. Y. C. Chow, S. T. Yuen, and C. H. Cho. Reduction of EGF is associated with the delay of ulcer healing by cigarette smoking. Am. J. Physiol. Gastrointest. Liver Physiol. 278: G10–G17, 2000.—Cigarette smoking is associated with peptic ulcer diseases. Smokers have lower levels of salivary epidermal growth factor (EGF) than nonsmokers. We investigated whether reduction of EGF...
Battish, Raman, Gao-Yuan Cao, Richard B. Lynn, Sushanta Chakder, and Satish Rattan. Heme oxygenase-2 distribution in anorectum: colocalization with neuronal nitric oxide synthase. Am. J. Physiol. Gastrointest. Liver Physiol. 278: G148–G155, 2000.—Recent investigations have suggested carbon monoxide (CO) as a putative messenger molecule. Although several studies have implicated the heme oxygenas...
In this article we have summarized the status of the system SANC version 0.41. We have implemented theoretical predictions for many high energy interactions of fundamental particles at the one-loop precision level for up to 4-particle processes. In the present part of our SANC description we place emphasis on an extensive discussion of an important first step of calculations of the one-loop amp...
Kaur, Baljeet S., Rodica Ouatu-Lascar, M. Bishr Omary, and George Triadafilopoulos. Bile salts induce or blunt cell proliferation in Barrett’s esophagus in an aciddependent fashion. Am J Physiol Gastrointest Liver Physiol 278: G1000–G1009, 2000.— Barrett’s esophagus (BE) results from acid and bile reflux and predisposes to cancer. We investigated the effect of bile salts, with or without acid, ...
Banks, William A., Cecilia M. Clever, and Catherine L. Farrell. Partial saturation and regional variation in the blood-to-brain transport of leptin in normal weight mice. Am J Physiol Endocrinol Metab 278: E1158–E1165, 2000.— Impaired blood-brain barrier transport of leptin into the arcuate nucleus has been suggested to underlie obesity in humans and outbred aging mice. Here, we used a brain pe...
