A structural comparison of the A and B subunits of Griffonia simplicifolia I isolectins
(Elsevier, 1984-02-15)
A structural comparison between the A and B subunits of the five tetrameric Griffonia simplicifolia I isolectins (A4, A3B, A2B2, AB3, B4) was undertaken to determine the extent of homology between the subunits. The first ...
Enkephalinase: Selective inhibitors and partial characterization
(Elsevier, 1980)
There are at least two types of enzymes in brain, endopeptidases and aminopeptidases, which metabolize enkephalins. Evidence is presented to suggest that enkephalinase, an endopeptidase cleaving at the Gly-Phe bond, is ...
Intrathecal bombesin-induced inhibition of gastrointestinal transit: requirement for an intact pituitary-adrenal axis
(Elsevier, 1986-05)
The role of the pituitary-adrenal axis in the inhibition of gastrointestinal transit caused by intrathecal administration of bombesin was examined. Bombesin (0.3-10 [mu]g) slowed transit by this route in a dose-related ...
A sensitive coupled HPLC/RIA technique for separation of endorphins: Multiple forms of B-endorphin in rat pituitary intermediate vs. anterior lobe
(Elsevier, 1981-08)
A technique is described which couples High Performance Liquid Chromatography (HPLC) to radioimmuno assays (RIA), thus achieving high sensitivity with good specificity. This method allows the separation and detection of ...
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 ...
Differences in hydroxysTEROL METABOLISM BETWEEN RAT AND MOUSE LEYDIG CELLS
(Elsevier, 1984-06)
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.) ...
