Prenatal and neonatal exposure to natural and synthetic estrogens induces developmental abnormalities in the male and female reproductive systems in several species. In hamsters, a single injection of diethylstilbestrol (DES) on the day of birth induces teratogenic and neoplastic changes throughout the female reproductive tract, apparently via a direct(More)
N-acetylneuraminic acid at the surfaces of rat cerebral cortex and liver mitochondria and derived mitoplasts (inner membrane plus matrix particles) was studied biochemically and electrokinetically . Rat cerebral cortex mitochondria in 0 .0145 M NaCl, 4.5 % sorbitol, pH 7.2 t 0.1, 0 .6 mm NaHCO3, had an electrophoretic mobility of 2.88 f 0.01 u/sec per v per(More)
The majority of human ovarian cancers originate from the surface epithelial (OSE) cells that surround the ovary. The incidence of OSE cancer is correlated with the number of ovulations that occur during fertile life. OSE cells remain quiescent but undergo rapid mitotic activity after ovulation to repair the wound. This increase in mitotic activity following(More)
N-acetylneuraminic acid at the surfaces of rat cerebral cortex and liver mitochondria and derived mitoplasts (inner membrane plus matrix particles) was studied biochemically and electrokinetically. Rat cerebral cortex mitochondria in 0.0145 M NaCl, 4.5% sorbitol, pH 7.2 +/- 0.1, 0.6 mM NaHCO(3), had an electrophoretic mobility of - 2.88 +/- 0.01 micro/sec(More)
Phosphaturic mesenchymal tumours are a heterogeneous set of bone and soft tissue neoplasms that can cause a number of paraneoplastic syndromes such as tumour induced osteomalacia. The term phosphaturic comes from the common finding that these tumours secrete high levels of fibroblast growth factor 23 which causes renal phosphate wasting leading to(More)
Frequently, as in missile control systems, linear differential equations are simultaneous with nonlinear but slower acting differential equations. The numerical solution of this type of system on a digital computer is significantly speeded up by approximating the forcing functions with polynomials, solving the linear equations exactly, and numerically(More)
