Wilms' tumor-aniridia association: Segregation of affected chromosome in somatic cell hybrids, identification of cell surface antigen associated with deleted area, and regional mapping of c-Ha-ras-1 oncogene, insulin gene, and beta-globin gene
(Kluwer Academic Publishers-Plenum Publishers; Plenum Publishing Corporation ; Springer Science+Business Media, 1984-09)
Fusion of an auxotrophic mutant hamster cell with the skin fibroblasts of a child with the Wilms' tumor-aniridia association produced clones which, on the one hand, contained the child's normal chromosome 11 and, on the ...
Incorporation of the cytochrome P-450 monooxygenase system into large unilamellar liposomes using octylglucoside, especially for measurements of protein diffusion in membranes
(Elsevier, 1984-05-31)
Cytochrome P-450 and NADPH cytochrome P-450 reductase were incorporated into large unilamellar lipid vesicles (200-300 nm in diameter) removing octylglucoside from mixed micelles by dialysis. The large size of the ...
Isolation and structure of the bacterial sex pheromone, cAD1, that induces plasmid transfer in Streptococcus faecalis
(Elsevier, 1984-12-03)
The Streptococcus faecalis sex pheromone cAD1, which is involved in the conjugative transfer of the hemolysin plasmid pAD1, has been isolated and its structure determined. Its Mr is 818 and its amino acid sequence is ...
Effects of lipoxygenase and cyclooxygenase inhibitors on glucose-stimulated insulin secretion from the isolated perfused rat pancreas
(Elsevier, 1984-04-30)
Some of the metabolites of arachidonic acid formed in the lipoxygenase and cyclooxygenase pathways stimulate insulin release. We studied the relative importance of each of these pathways in the modulation of glucose-induced ...
The nusA recognition site : Alteration in its sequence or position relative to upstream translation interferes with the action of the N antitermination function of phage lambda
(Elsevier, 1984-12-25)
The phage [lambda] transcription antitermination protein, pN, acts with host factors. Nus, at sites on the phage genome, nut, to render RNA polymerase resistant to subsequent downstream termination signals. The NusA protein ...
The effects of ketamine, phencyclidene and lidocaine on catecholamine secretion from cultured bovine adrenal chromaffin cells
(Elsevier, 1984-10-29)
The ability of ketamine, phencyclidine and analogues to alter catecholamine secretion from cultured bovine adrenal chromaffin cells was investigated. Both ketamine and phencyclidine specifically inhibited nicotinic ...
Pólya-like urns and the Ewens' sampling formula
(Springer-Verlag, 1984-08)
A Markov process of partitions of the natural numbers is constructed by defining a Pólya-like urn model. The marginal distributions of this process are the Ewens' sampling distributions of population genetics.
Role of oxygen reactive species in egg-induced granulomatous inflammation
(Elsevier, 1984-07-18)
The role of oxygen reactive species in granulomatous hypersensitivity was explored using a model of pulmonary granulomas induced by intravenous injection of eggs from the parasite . Macrophages from sychronously developing ...
Novel inhibition of carbonic anhydrase isozymes I, II and III by carbamoyl phosphate
(Elsevier, 1984-01-09)
Carbamoyl phosphate has been shown to inhibit carbonic anhydrase (CA) isozymes CA I, CA II and CA III. This physiologically important molecule is the most potent, naturally occurring inhibitor of carbonic anhydrase yet ...
Effects of somatostin on food intake in rats
(Elsevier, 1984-08-13)
We examined the possibility that somatostatin, a tetradecapeptide distributed in the gut and the central nervous system, may influence food intake and behavior in rats. Although intravenously infused somatostatin did not ...
