The stimulation of cerebral N2-methyl- and N22-dimethyl guanine-specific tRNA methyltransferases by methionine sulfoximine: An study
(Elsevier, 1977-06-20)
The administration of a single convulsant dose or of multiple subconvulsant doses of L-methionine-dl-sulfoximine (MSO) to 18-day old rats results in a significant elevation of the specific activity of cerebral tRNA ...
Choosing category size in a stage projection matrix
(Springer-Verlag, 1978-01)
A basic problem associated with choosing category size in a stage projection matrix is described. “Errors of estimation” are large if the category size is chosen too small and “errors of distribution” are large if the ...
Comparative ultrastructural study of normal and grafted skin in the frog, Rana pipiens , with special reference to neuroepithelial connections
(Springer-Verlag, 1973-06)
Recent investigations have suggested specific differences in back and belly skin in anurans which appear to influence the quality of reflex responses obtained from various areas of the animals body. The present investigation ...
Comparative biochemical studies of osmo-regulation in sipuncula--I. Steady-state characteristics of two sipunculids in full-strength sea water
(Elsevier, 1974)
1. 1. Chemical analyses are reported for centrifuged coelomic fluid, body wall, retractor muscles and coelomocytes of the Sipunculids Themiste dyscritum and Phascolopsis gouldi acclimated to full-strength sea water.2. 2. ...
Banding pattern and fibrillogenesis of ceratotrichia in shark fins
(Wiley Subscription Services, Inc., A Wiley Company, 1977-11)
Study by light microscopy, scanning electron microscopy and transmission electron microscopy of the distribution, structure and growth of ceratotrichia in the anterodorsal fin of a lemon shark, Negaprion brevirostris , ...
Olfactory and vomeronasal deafferentation of male hamsters: Histological and behavioral analyses
(Elsevier, 1977-05-06)
Deafferentation of the vomeronasal system by cutting the vomeronasal nerves severely impaired mating behavior in 44% of male hamsters over a 1-2 month period of postoperative testing, but the remaining males mated normally ...
Regeneration in free grafts of normal and denervated muscles in the rat: Morphology and histochemistry Supported by grants from the Muscular Dystrophy Associations of America and a scientific exchange between the Academies of Sciences of the United States and Czechoslovakia. Reported earlier in abstract form (Carlson and Gutmann, 1973).
(Wiley Subscription Services, Inc., A Wiley Company, 1975-09)
Intact soleus and extensor digitorum longus muscles in the rat were freely grafted to the contralateral leg after either no preliminary tretment or 14 days prior denervation. Normal muscle grafts during the first week were ...
Osmoregulation in Blaberus craniifer after parenteral injections of NaCl solutions
(Elsevier, 1977)
1. 1. After injection of NaCl into the abdominal hemocoel of Blaberus craniifer, the osmotic concentration of antennal hemolymph peaked at 1.25hr and returned to pre-injection concentration by 21 hr. The mean plasma clearance ...
