Previous studies have shown that endotoxin (lipopolysaccharide [LPS])-induced death can be prevented by preincubating LPS with lipoproteins in vitro or by infusing large quantities of lipids into animals prior to LPS administration. In the present study we determined whether physiological

We used an analytical color fluorescence electron microscope to observe cathodoluminescence (CL) in the corpus luteum of rat. CL was emitted from lipid droplets and has a typical spectrum of two peaks at wavelengths of 320 and 430 nm. The
Reactive oxygen species, such as superoxide, hydrogen peroxide, and lipid peroxides, impair luteal function. Vitamin E, a lipophilic antioxidant vitamin, provides a major avenue of protection by scavenging free radicals and terminating lipid peroxidation. We previously showed that ovarian vitamin
These studies were done to examine the effect of gonadotropin on rat luteal 3-hydroxy-3-methylglutaryl coenzyme A (HMG CoA) reductase activity (the rate-limiting step in cholesterol biosynthesis) in ovaries of pregnant mare's serum gonadotropin (PMSG)-human chorionic gonadotropin (hCG) primed rats. Administration

Barrier perturbation stimulates epidermal cholesterol synthesis, which plays an important role in restoring barrier function. In the present study, we examined whether changes in serum cholesterol levels or nutrition regulate epidermal cholesterol synthesis in hairless mice. Serum cholesterol levels were
