Postnatal ontogeny of acetylated and non-acetylated B-endorphin in rat pituitary
(Elsevier, 1983)
Extracts of the anterior lobe and intermediate lobe of postnatal (P) (Day P1, P7, P14, P21, P28, P35, P42) and adult male Spraque-Dawley rats were analyzed by both a Beta-endorphin (B-END) radioimmunoassay and a radioimmunoassay ...
Lead activates calmodulin sensitive processes
(Elsevier, 1983-09-05)
The effect of lead on two calcium sensitive processes was determined. Micromolar concentrations of lead successfully replaced calcium in the activation of calmodulin-sensitive phosphodiesterase and in the promotion of ...
Further studies on a hybrid cell-surface antigen associated with human chromosome 11 using a monoclonal antibody
(Kluwer Academic Publishers-Plenum Publishers; Plenum Publishing Corporation ; Springer Science+Business Media, 1983-07)
A monoclonal antibody has been obtained that recognizes an antigen encoded by human chromosome 11. We present evidence that this monoclonal antibody recognizes the same or a similar antigenic activity as that previously ...
The mechanism of amine inhibition of the photosynthetic oxygen evolving complex : Amines displace functional chloride from a ligand site on manganese
(Elsevier, 1983-10-17)
Amines inhibit photosynthetic oxygen evolution by binding to manganese in the oxygen evolving complex. This inhibition is more effective if chloride is absent. Steady-state kinetic analyses show that ammonia and chloride ...
Immunological comparison of the usual and atypical human serum cholinesterase phenotypes
(Kluwer Academic Publishers-Plenum Publishers; Plenum Publishing Corporation ; Springer Science+Business Media, 1983-02)
Antiserum prepared against highly purified usual human serum cholinesterase (the most common phenotype) cross-reacted identically with the atypical serum cholinesterase. The level of circulating atypical enzyme protein, ...
II. Biochemical mechanisms in the phosphatidylinositol effect
(Elsevier, 1983-05-02)
Stimulated labeling of phospholipids from 32Pi is a hallmark of activation of a variety of cell surface receptors. In the case of the central nervous system, the response can reflect muscarinic activation. Recent studies ...
Downy woodpecker foraging behavior: foraging by expectation and energy intake rate
(Springer-Verlag, 1983-05)
I describe an artificial patch system that was used to study the foraging behavior of free-roaming downy woodpeckers ( Picoides pubescens ) in a woodlot in southeastern Michigan. The artificial “patches” used were thin ...
Receptor binding, antagonist, and withdrawal precipitating properties of opiate antagonists
(Elsevier, 1983-06-20)
A number of opiate antagonists and the dextro isomers of some of these drugs were studied for antagonism of acute opiate effects on ilea isolated from opiate-naive guinea pigs, precipitation of a withdrawal contraction of ...
Comparative distribution of opiate receptors and three opioid peptide neuronal systems in rhesus monkey central nervous system
(Elsevier, 1983)
Using combined autoradiography-immunocytochemistry, the anatomical distribution of [3H]naloxone-labelled opiate receptors was compared to the loci of neuronal systems immunoreactive for [beta]-endorphin, [Leu]enkephalin ...
Systemic and intracerebroventricular effects of opioid peptides in withdrawn morphine-dependent rhesus monkeys
(Elsevier, 1983)
The effects of the degradation-resistant enkephalin analogs FK 33-824 and metkephamid were determined after systemic and intracerebroventricular (i.c.v.) administration in withdrawn morphine-dependent rhesus monkeys. Both ...
