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 ...
Control of acetylcholine receptor mobility and distribution in cultured muscle membranes. A fluorescence study
(Elsevier, 1978-07-20)
The molecular control of the distribution and motion of acetylcholine receptors in the plasma membrane of developing rat myotubes in primary cell culture was investigated by fluorescence techniques. Acetylcholine receptors ...
The heat capacity and thermodynamic functions of crystalline and liquid triptycene
(Elsevier, 1970-03)
The heat capacity of the propeller-shaped molecule triptycene (C20H14) was measured from 5 to 550 K. No anomaly other than melting was apparent, and the sample (99.999 per cent pure, as determined by analysis of the melting ...
Role of phospholipid in electron transfer in a reconstituted liver microsomal enzyme system containing cytochrome P-450
(Elsevier, 1971-08)
Phosphatidylcholine, which is required for fatty acid, hydrocarbon and drug hydroxylation in a reconstituted liver microsomal enzyme system, is essential for the enzymatic reduction of cytochrome P-450.
Stimulation of uterine nonhistone protein phosphorylation and nuclear protein kinase activity by estradiol-17[beta]
(Elsevier, 1976-06-18)
Changes in the phosphorylation of nonhistone chromosomal proteins have been followed in rat uterus stimulated by 17[beta]-estradiol. Isolated uteri were found to incorporate 32Pi into nonhistone proteins via an endogenous ...
Thermodynamics of the lanthanide halides I. Heat capacities and Schottky anomalies of LaCl3, PrCl3, and NdCl3 from 5 to 350 K
(Elsevier, 1976-12)
The heat capacities of LaCl3, PrCl3, and NdCl3 have been measured from 5 to 350 K by adiabatic calorimetry. No co-operative thermal anomalies were seen in the temperature range investigated but substantial magnetic ...
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 ...
