Example Input: Abstract: Physiological concentrations of L-T4 were found previously to stimulate Ca2+-ATPase activity in vitro in reticulocyte membranes from female rabbits and to inhibit this enzyme in reticulocyte membranes from males. In these previous studies, preincubation of intact cells or ghosts with testosterone (5 X 10(-11) M) converted female-source reticulocyte membranes to male-type responsiveness to thyroid hormone (inhibition of Ca2+-ATPase activity). Preincubation of reticulocyte membranes with 17 beta-estradiol (5 X 10(-11) M) converted male-source membranes to female-type responsiveness (stimulation by L-T4 of membrane Ca2+-ATPase activity). Using this sex steroid-sensitive thyroid hormone-dependent membrane enzyme system, we investigated the structure-activity relationships of analogs of sex steroids and unrelated steroids. 5 beta-Androstanes were active compared to testosterone in assays using female-source membranes, while 5 alpha-androstanes were less active. Within the 5 beta-androstanes, activity was dependent on at least one hydroxyl group at the C3- or C17-position. Nongonadal steroids tested were less active, establishing specificity of the sex steroid effect in assays using female-source membranes. Assayed in male-source membranes, estrone and 3-hydroxy-1,3,5-(10)7-estratraen-17-one (equilin) were active compared for estrogen effect with 17 beta-estradiol, while estriol was less active. The activities of hydrocortisone and aldosterone were 76% and 71%, respectively, in this system. These structure-activity relationships are distinct from those described for gonadal steroid-cytoplasmic binding proteins or nuclear interactions, and represent a novel sex steroid-thyroid hormone effect on activity of a membrane enzyme.

Example Input: Abstract: In search of a practical biochemical test that will reflect hepatic steatosis, we assessed the significance of serum cholinesterase activity in 48 patients with nonalcoholic fatty liver, 16 obese subjects without fatty liver, 30 cases of chronic persistent hepatitis, 38 cases of chronic active hepatitis, and 20 cases of liver cirrhosis. Increased cholinesterase activity was observed in nonobese as well as obese patients with fatty liver, whereas obese subjects without fatty liver showed levels in the upper normal range. When we set a cutoff level above the upper normal limit, half of the patients with fatty liver showed values above it, with only a few overlaps with other patients. When obese patients with fatty liver took a low-caloric diet, cholinesterase activity decreased, clearly reflecting improvement of hepatic steatosis. Thus, measurement of cholinesterase activity is of diagnostic value and an alternative to computed tomography in hepatic steatosis, and will provide a practical measure for the assessment of effects during follow-up.

Example Input: Abstract: The development of mouse and human embryos was assessed in human amniotic fluid to determine its suitability as a culture medium for human in vitro fertilization (IVF). Two-cell mouse embryos developed to blastocysts after 72 hours at rates similar to that in Whittingham's T6 + 10% fetal calf serum. Significantly more mouse embryos hatched in amniotic fluid. No difference was found between individual patient's amniotic fluids obtained at 16 to 21 weeks' gestation. A preliminary trial comparing amniotic fluid with T6 + maternal serum in human IVF showed no significant difference in fertilization rate and embryo development during 42 to 48 hours in vitro. Expanded blastocysts were obtained in amniotic fluid after 5 days in vitro. Four pregnancies were obtained in 9 patients' transferred embryos grown in amniotic fluid and with 2 or 12 patients' transferred embryos grown in T6 + maternal serum.
