Role of gangliosides in gonadotropin and cholera enterotoxin stimulated steroidogenesis in isolated rat ovarian cells
(Elsevier, 1978-07-28)
Ovarian cells isolated from 26 day old rats responded to hCG (10 ng/ml) and cholera enterotoxin (100 ng/ml) with a forty-five to fifty-fold increase in progesterone production. Both cholera enterotoxin and hCG-stimulated ...
Stress induced grooming in the rat -- An endorphin mediated syndrome
(Elsevier, 1979-07)
Exposure of adult male Sprague--Dawley rats to a non-traumatic noise-light stress procedure subsequently increased grooming behavior in a novel environment. The grooming syndrome was marginally facilitated by adrenalectomy ...
Oxygen uptake in green iguana (Iguana iguana) injected with bacteria
(Elsevier, 1979-04)
1. 1.|Green iguanas (I. iguana) were maintained at a constant body temperature of 35.5[deg]C and injected with either saline or a dose of bacteria which had been previously shown to induce a fever by 3 h post-injection.2. ...
Development of crystalline inclusions (“ergosterol crystals”) in Neurospora crassa
(Springer-Verlag, 1976-09)
Development of crystalline inclusions (“ergosterol crystals”) in “snowflake”, a morphological mutant of Neurospora crassa has been examined. The inclusions which arise in membranebound organelles appear as electron dense ...
The free autografting of entire limb muscles in the cat: Morphology Supported by grants by the Muscular Dystrophy Association to BMC and JAF and an MDA Postdoctoral Fellowship to SAM.
(Wiley Subscription Services, Inc., A Wiley Company, 1977-08)
Normal or pre-denervated extensor digitorum longus (EDL) muscles were successfully grafted in place of the contralateral EDL muscles in cats. Histological preparations of 57 grafts were examined at intervals from 4 to 170 ...
Effect of divalent metal ion binding on the Raman spectrum of ATP in aqueous solution
(Elsevier, 1970-01-23)
The apparent dissociation constants for the secondary H+ of HATP-3, CaHATP-1, MgHATP-1 and ZnHATP-1 were determined by studying the pH dependent frequency of a particular line in the Raman spectrum of ATP. We obtained the ...
Inhibition of cellular ATP-hydrolyzing activity by tricyclic antidepressants and phenothiazine tranquilizers
(Elsevier, 1975-05-01)
In a variety of cellular and subcellular preparations, total ATP-hydrolyzing activity was potently inhibited by tricyclic antidepressants (TA) and phenothiazine tranquilizers (PT). In leukocytes, preincubation of the cells ...
Two routes for synthesis of phosphoenolpyruvate from C4-dicarboxylic acids in
(Elsevier, 1974-08-19)
Mutants of defective in both phosphoenolpyruvate carboxykinase and phosphoenolpyruvate synthetase are unable to use C4-dicarboxylic acids such as succinate and malate as carbon and energy sources for growth. Revertants ...
Deficit in active avoidance learning in rats following penicillin injection into hippocampus
(Elsevier, 1971-06)
Penicillin was found to cause epileptiform (spike) activity when injected into the hippocampus of male rats. Animals so prepared were found to be severely impaired in the acquisition of a two-way active avoidance task. ...
