Background
Ovarian stimulation for assisted reproductive technology (ART) overcomes the physiologic process to develop a single dominant follicle. However, following stimulation, egg recovery rates are not 100%. The objective of this study is to determine if the follicular fluid hormonal environment is associated with oocyte recovery. 相似文献132.

In a field trial of 1,257 patients receiving methoxyflurane, trichloroethylene, and nitrous-oxide/oxygen for the relief of pain in labour methoxyflurane has been shown to have certain advantages which support its use in midwifery practice. The trial confirms our objective method for screening an inhalational agent as an obstetric analgesic. 相似文献

When cells of the cellular slime mold Dictyostelium discoideum differentiate from a nonsocial amoeboid form to a cohesive, aggregating form, they synthesize a lectin-like protein called discoidin, which is present on the cell surface. It is now reported that discoidin consists of two distinct lectins, designated discoidin I and discoidin II, which, although similar in some respects, differ in their electrophoretic mobilities, isoelectric points, subunit molecular weights, amino acid compositions, tryptic peptide maps, the erythrocyte species which they agglutinate, and the sensitivity of their agglutination activity to inhibition by monosaccharides. Furthermore, discoidins I and II differ in their developmental regulation as evidenced by the distinct time courses of their appearance during differentiation. 相似文献

Cation/proton antiport systems in escherichia coli: properties of the sodium/proton antiporter. 总被引:9,自引:0,他引:9
The sodium/proton antiport system of Escherichia coli has been characterized by the effect of Na+ on the pH gradient established by respiration in everted membrane vesicles. The system has equal affinity for Na+ and Li+. Between pH 7 and 9 dissipation of Δψ, membrane potential, has no effect on the affinity for Na+ but decreases the V of the antiport reaction. Uptake of 22Na+ by everted membrane vesicles was observed using flow dialysis. 相似文献
