Entropy and heat capacity of europium(III) bromide from 5 to 340 K
(Elsevier, 1975-07)
The heat capacity of a polycrystalline sample of EuBr3 has been measured from 5 to 340 K and found to be without transitions in this region. Values of the thermodynamic functions Cp(T), {So(T) - So(5 K)}, and {Ho(T) - Ho(5 ...
Stimulation by prostaglandin E2 of glucagon and insulin release from isolated rat pancreas
(Elsevier, 1975-09)
To ascertain whether prostaglandins (PG) may play a role in the secretion of glucagon and in an attempt to elucidate the conflicting observations on the effects of PG on insulin release, the isolated intact rat pancreas ...
The inhibitive effects of steroid analogues in the binding of tritiated 5[alpha]-dihydrotecto3terone to receptor proteins from rat prostate tissue
(Elsevier, 1975-02)
The relationship between molecular structure and the binding potential of steroids to receptor proteins was investigated. Twenty-four selected steroids were studied in minced incubations of rat pro state tissue. Measurements ...
Properties of a partially-purified preparation of the prostaglandin-forming oxygenase from sheep vesicular gland
(Elsevier, 1975-11)
The fatty acid oxygenase of sheep vesicular glands was solubilized with Tween-40 and purified 60-fold using ammonium sulfate precipitation and DEAE-cellulose chromatography. Glycerol (50%) stabilized the activity at all ...
Nephrotoxic effects of tetanus toxin: An ultrastructural study
(Elsevier, 1975-12)
Generalized nephrotoxicity was observed in the rat as early as 6 hr after intramuscular injection of 1000 of tetanus toxin. The most striking morphological changes, including swelling and rupture of the mitochondria, ...
