(1) Isotope competition studies indicated that the pathway was regulated by isoleucine.
(2) These channels may, at least in some cases, be responsible for the generation of pacemaker depolarizations, thereby regulating firing behaviour.
(3) Cellulase regulation appears to depend upon a complex relationship involving catabolite repression, inhibition, and induction.
(4) Each process has been linked to the regulation of cholesterol accretion in the arterial cell.
(5) Down and up regulation by peptides may be useful for treatment of cough and prevention of aspiration pneumonia.
(6) Comparison of wild type and the mutant parD promoter sequences indicated that three short repeats are likely involved in the negative regulation of this promoter.
(7) The vascular endothelium is capable of regulating tissue perfusion by the release of endothelium-derived relaxing factor to modulate vasomotor tone of the resistance vasculature.
(8) To examine the central nervous system regulation of duodenal bicarbonate secretion, an animal model was developed that allowed cerebroventricular and intravenous injections as well as collection of duodenal perfusates in awake, freely moving rats.
(9) The observed relationship between prorenin and renin substrate concentrations might be a consequence of their regulation by common factors.
(10) We report a series of experiments designed to determine if agents and conditions that have been reported to alter sodium reabsorption, Na-K-ATPase activity or cellular structure in the rat distal nephron might also regulate the density or affinity of binding of 3H-metolazone to the putative thiazide receptor in the distal nephron.
(11) This study was designed to investigate the localization and cyclic regulation of the mRNA for these two IGFBPs in the porcine ovary, RNA was extracted from whole ovaries morphologically classified as immature, preovulatory, and luteal.
(12) At the same time the duodenum can be isolated from the stomach and maintained under constant stimulus by a continual infusion at regulated pressure, volume and temperature into the distal cannula.
(13) The effects of glucagon-induced insulin secretion upon this lipid regulation are discussed that may resolve conflicting reports in the literature are resolved.
(14) In this phase the educational practices are vastly determined by individual activities which form the basis for later regulations by the state.
(15) Thus, human bronchial epithelial cells can express the IL-8 gene, with expression in response to the inflammatory mediator TNF regulated mainly at the transcriptional level, and with elements within the 5'-flanking region of the gene that are directly or indirectly modulated by the TNF signal.
(16) The results suggest differential regulation of IL-6 expression between fibroblasts and macrophages.
(17) This paper has considered the effects and potential application of PFCs, their emulsions and emulsion components for regulating growth and metabolic functions of microbial, animal and plant cells in culture.
(18) These data indicate that CSF levels are not inversely related to the blood neutrophil count in chronic idiopathic neutropenia and suggest that CSF is not a hormone regulating the blood neutrophil count in a manner analogous to the erythropoietin regulation of circulating erythrocyte levels.
(19) Comprehensive regulations are being developed to limit human exposure to contamination in drinking water by the United States Environmental Protection Agency (EPA) under the authority of the Safe Drinking Water Act (SDWA).
(20) This novel mechanism of receptor regulation, named transmodulation, should be distinguished from the reduction in total receptor number caused by the homologous ligand (downregulation) and from the change in affinity produced by the binding of agonists or antagonists to the same receptor site.

(a.) Composed of small plates, as of horn or metal, overlapping like tiles; -- said of a kind of ancient armor.
