Sexual selection, additive genetic variance and the "phenotypic handicap"
(Elsevier, 1983-04-07)
Developmental changes in protein carboxylmethylation and in the benzodiazepine receptor proteins in rat brain
(Elsevier, 1983-11-15)
The intraventricular administration of [3H-methyl]-methionine resulted in a steady increase in carboxyl-[3H]methylated protein formation in the brain of developing rats (2-42 days). The analysis by gel filtration on ...
Effect of hydrostatic pressure on halothane-induced depression of mitochondrial respiration
(Elsevier, 1983-04-04)
Anesthetized animals are awakened when subjected to increased atmospheric pressure. Whether all phenomena associated with the anesthetic state are similarly reversed is not known. Since the anesthetic halothane produces a ...
Evidence for the existence of gonadotropin receptors in the nuclei isolated from rat ovary
(Elsevier, 1983-02-28)
Specific binding of radiolabeled human chorionic gonadotropin (hCG) to nuclei isolated from pseudopregnant rat ovaries was studied. Incubation of cultured luteal cells or isolated nuclei with fluorescein isothiocyanate ...
Ontogeny of opioid and related peptides in the rat CNS and pituitary: An immunocytochemical study
(Elsevier, 1983)
The development of proopiomelanocortin (POMC) derived peptides was compared to that of leucine-enkephalin ([Leu]ENK) and dynorphin A (DYN-A) immunoreactivity (i.r.) in the rat CNS and pituitary gland. POMC i.r. appeared ...
An artifactual component of drug-protein binding generated in vitro
(Elsevier, 1983-07-11)
In the course of investigating the binding of imipramine to soluble cellular fractions from brain and leukocytes using equillibrium dialysis, an artifactual binding component was produced. On Scatchard and double-reciprocal ...
Muscarinic stimulation of phospholipid turnover in dissociated avian salt gland cells
(Elsevier, 1983-05-02)
Addition of carbamylcholine to 32P-prelabeled dissociated avian salt gland cells resulted in increased turnover of phosphatidic acid, phosphatidylinositol, phosphatidylinositol 4-phosphate and phosphatidylinositol ...
Some of the [alpha]-NH2-acetylated [beta]-endoprhin-like material in rat and monkey pituitary and brain is acetylated [alpha]- and [beta]-endorphin
(Elsevier, 1983)
There are several studies demonstrating the existence of [alpha]-NH2-acetylated (N-Ac) forms of [beta]-endorphin in the intermediate lobe of several species (1,4,6). These include N-Ac-[beta]-endorphin(1-31), N-Ac-[beta] ...
Prostaglandin E1 and prostaglandin I2 modulation of superoxide production by human neutrophils
(Elsevier, 1983-06-15)
15(S)-15-methyl-prostaglandin E1 and prostaglandin I2 rapidly and reversibly inhibit formyl-methionyl-leucyl-phenylalanine induced superoxide production by human neutrophils. In contrast, 15(S)-15-methyl-prostaglandin E1 ...
On the within-sibship variance
(Elsevier, 1983-04)
An approximate formula for the expected within-sibship genotypic variance of a polygenic, diallelic, additive character is obtained for arbitrary recombination between the loci affecting the character. The formula is exact, ...
