Solute concentration in the kidney-- I. a model of the renal medulla and its limit cases
(Elsevier, 1976)
We develop a general model of the renal medulla that is similar in geometry to the models reported by others. Two solutes are assumed to be present, one to play the role of salt and the other that of urea and similarly ...
A game to help students comprehend enzyme structure and mechanism of action
(Elsevier, 1976-01)
Aspirin as a quantitative acetylating reagent for the fatty acid oxygenase that forms prostaglandins
(Elsevier, 1976-01)
A selective acetylation of the prostaglandin-forming fatty acid oxygenase (part of the prostaglandin "synthetase" system) occurs with 100 [mu]M concentrations of aspirin (acetylsalicylic acid). The amount of acetylation, ...
Stimulation of the gerbil's gustatory receptors by disaccharides
(Elsevier, 1976-07-16)
The gustatory responses from the chorda tympani nerve of the Mongolian gerbil, Meriones unguiculatus, were with 13 disaccharides. Sucrose was the most stimulatory sugar.The ability of fructosyl glycosides to stimulate amy ...
Progesterone: Examination of its postulated inhibitory actions on lordosis during the rat estrous cycle
(Elsevier, 1976-09)
Three experiments tested whether the inhibitory effects of progesterone could be of physiological significance in regulating the duration of behavioral estrus in female rats. In animals displaying 5 day estrous cycles, a ...
Synthesis of potential antiprogestogens
(Elsevier, 1976-01)
Acylated derivatives of 17[alpha]-hydroxyprogesterone were prepared in order to test the hypothesis that dialkylamino alkyl moieties have the effect of transforming progestogens into antiprogestogens. This approach has ...
A psychodynamic approach to suicide prevention
(Kluwer Academic Publishers; Human Sciences Press ; Springer Science+Business Media, 1976-12)
This paper sets forth a new theoretical approach to understanding the psychological etiology of suicide. The theory is demonstrated by an in-depth clinical case example, and its implications for the management of the ...
Preentry issues in consultation

A shift from phospholipid to triglyceride synthesis when cell division is inhibited by trans-fatty acids
(Elsevier, 1976-10)
The yeast mutant Saccharomyces cerevisiae (KD 46) requires added unsaturated fatty acid for growth. When cell growth was inhibited by the presence of trans-acids there was a marked inhibition of oleate esterification into ...
Neurite outgrowth from explanted Xenopus retina: An effect of prior optic nerve section
(Elsevier, 1976-08-27)
Experimental conditions are described for the in vitro study of explanted eyes from embryos of Xenopus laevis and of retinas from older larvae. When eyes are explanted from embryos of stages 25-34, a rapid outgrowth of ...
