In the present study we have examined the presence of Fas, Fas ligand (FasL), and p53 in rat granulosa cells during follicular development and atresia, especially in relation to the granulosa cell cycle progression and the onset of granulosa cell apoptosis. Fas, FasL, and p53 proteins were immunolocalized, and their contents were determined by Western(More)
A transdermal therapeutic system (TTS) for administration of testosterone was tested in healthy and hypogonadal men. To ensure adequate absorption, a testosterone-loaded film was applied to the scrotal skin. The TTS was designed to last for 22 h; over this time serum testosterone levels in normal men were moderately increased, with concentration curves(More)
The present study examines the inhibitory action of progesterone (P) on prolactin (PRL) gene expression in the anterior pituitary of ovariectomized, estradiol (OVX+E) treated adult rats. A single injection of P (1 mg) was administered s.c. to OVX+E treated rats, and animals were killed at 3, 6, 9, and 36 h following P administration. Northern blot analysis(More)
In the present study, we investigated the effect of agelasine D (AD) on osteoclastogenesis. Treatment of bone marrow macrophages (BMMs) with receptor activator of nuclear factor κB ligand (RANKL) resulted in a differentiation of BMMs into osteoclasts as evidenced by generation of tartrate-resistant acid phosphatase (TRAP)-positive, multinucleated cells and(More)
This study was undertaken to observe the effects of organic or inorganic calcium antagonists and to investigate the involvement of cyclic nucleotides in regulating the vascular tone in the chorionic artery from normal or preeclamptic placenta. KCI and prostaglandin (PG) F2 alpha produced marked and constant contractions in chorionic arterial preparations of(More)
The amino acid L-glutamate is a major excitatory neurotransmitter in the central nervous system of vertebrates. NMDA (N-methyl-d-aspartate) is one of the L-glutamate receptor subtypes. During a critical period of early postnatal development, the visual cortex is susceptible to experience-dependent modification of neuronal responses. Recently, the activation(More)
