A method to reduce interference by sucrose in the detection of thiobarbituric acid-reactive substances
(Elsevier, 1984-03)
A thiobarbituric acid (TBA) reaction for measuring lipid peroxidation products was evaluated for interference by several ingredients commonly used in solutions to prepare or analyze tissue homogenates or subcellular ...
Characterization of a circular thin film plasma source for atomic emission spectroscopy
(Elsevier, 1985)
A plasma source for analytical atomic emission spectroscopy is described based on the electrical vaporization by capacitive discharge of a thin Ag film deposited on a polycarbonate membrane filter. The source is designed ...
Two-particle continuous-time random walks and binary reactions in disordered media
(Elsevier, 1984-02-10)
The relation between unary-(trappihg) and binary (mutual annihilation) reactions in disordered systems is studied in the framework of the continuous-time random walk. It is found that if the waiting-time distribution of ...
Coagulation in a continuously stirred tank reactor
(Elsevier, 1985-05)
Smoluchowski's coagulation equation with coagulation rates Kij [is proportial to] (ij)[omega] describing the temporal evaluation of the size distribution ck (concentration of k-mers) is studied in the presence of a source ...
Progress in modeling heat capacity versus temperature morphology
(Elsevier, 1986-12-15)
After discussion of other models for representing heat capacities, the volumetric model used in resolution of lanthanide Schottky contributions over the cryogenic range and a more recent single-parameter formula to represent ...
Differences in hydroxysTEROL METABOLISM BETWEEN RAT AND MOUSE LEYDIG CELLS
(Elsevier, 1984-06)
Evidence for a regulatory role of CTP : Choline phosphate cytidylyltransferase in the synthesis of phosphatidylcholine in fetal lung following premature birth
(Elsevier, 1981-07-24)
The sequence of reactions which function to incorporate choline into phosphatidylcholine was investigated in lung from fetuses following premature delivery. The rate of [methyl-14C]choline incorporation by rat lung slices ...
Electroencephalographic assessment of the role of [delta] receptors in opioid peptide - induced seizures
(Elsevier, 1984-12)
DPDPE ([D-Pen2, D-Pen5]-Enkephalin) and DPLPE ([D-Pen2, L-Pen5]-Enkephalin) are conformationally-constrained cyclic analogs of enkephalin with high selectivity for [delta] opioid receptors. Intracerebroventricular (i.c.v.) ...
Strategies for studying opioid peptide regulation at the gene, message and protein levels
(Elsevier, 1984)
Three opioid peptide precursors have been isolated and characterized in endocrine and nervous tissue: pro-opiomelanocortin, pro-enkephalin, and pro-dynorphin. Since each of those opioid peptide systems have been extensively ...
