Expression and regulation of cytochrome P-450I genes (CYP1A1 and CYP1A2) in the rat alimentary tract
(Elsevier, 1992-12-29)
Cytochrome P-450 (P450) enzymes in the mucosa of the alimentary tract may be involved in the activation and/or inactivation of ingested xenobiotics and procarcinogens. Since the multiple P450 enzymes have overlapping ...
Thermodynamics of the monohydrogen difluorides V. Melting thermodynamics of NH4HF2
(Elsevier, 1976-03)
The heat capacity of ammonium hydrogen difluoride was extended from 300 to 450 K by adiabatic calorimetry in order to study the melting phenomenon and provide thermodynamics into the liquid region. The corrected enthalpy ...
Leukotriene C4 induces vasogenic cerebral edema in rats
(Elsevier, 1984-06)
Leukotriene C4 (LTC4) is reported to neither contract nor relax isolated human cerebra artdial strips (1), but in skin LTC4 will increase vascular permeability in post capillary venules, increase blood flow (2) and elicit ...
Small angle X-ray scattering from coal-derived liquids
(Elsevier, 1982-05)
Small angle X-ray scattering measurements were used to determine the size and shape of asphaltene and preasphaltene micelles in solution. The fraction of the coal-derived liquids forming micelles in solution was as high ...
Interaction of linear manno-oligosaccharides with three mannose-specific bulb lectins. Comparison with mannose/glucose-binding lectins
(Elsevier, 1992-05-22)
Three new mannose-binding lectins, isolated from daffodil (NPA), amaryllis (HHA), and snowdrop (GNA) bulbs, are capable of precipitating with a linear mannopentaose (Man[alpha]1-3Man[alpha]1-3Man[alpha]1-3Man[alpha]1-2Man). ...
Phosphate entry into erythrocytes at high levels
(Elsevier, 1962-05-21)
Human red blood cells reach an equilibrium of phosphate distribution at 37[deg] much faster with 0.11 M or intermediate levels than with 0.02 M and lower phosphate levels. Other divalent anions added to 0.02 M phosphate ...
Characterization of gastrin amidation in the rat and porcine antrum: comparison with the pituitary
(Elsevier, 1990-04-24)
The formation of biologically active gastrin from glycine-extended processing intermediates occurs via the action of a peptide [alpha]-amidating enzyme. The observation that gastrin exists primarily as unamidated precursors ...
