Cu(2+)-Zn2+ superoxide dismutase (SOD-1) is a ubiquitously synthesized eukaryotic enzyme with a variety of important roles in mammalian development and physiology. With the goal of better understanding the structure and regulation of this gene, we have cloned and analyzed the genomic structure of the mouse SOD-1 gene. The murine sequence has an intron:exon(More)
Human fetal membranes, taken from 30 patients submitted to caesarean section during the final stages of gestation and labor, were examined in order to evaluate the presence and characteristics of the oxytocin receptor. The presence of oxytocin receptors in human fetal membranes, both in the amnion and in the chorion-decidua, was demonstrated in this study.(More)
Arylsulfatase (EC activity in human stromal cells isolated from specimens of histologically normal proliferative endometrium was increased several-fold during culture for 8-15 days in RPMI-1640 medium plus 10% charcoal-treated fetal bovine serum in the presence of a mixture of ovarian hormones (36 nM estradiol, 1 microM medroxyprogesterone acetate,(More)
The sleep pattern and conditions at the time of awakening were investigated by means of polygraphy and tests in 6 healthy adult volunteers following administration of amineptine. The drug was found to increase the number and duration of the REM phases, without affecting the overall sleeping time but reducing sleep latency. The tests carried out revealed a(More)
Steroid receptors, prostaglandin output and enzymatic activities were determined in explants derived from human endometrium exposed to natural interferon-beta (IFN-beta). Receptors and cell metabolism were evaluated before culturing the tissue fragments and after a 3-day treatment with varying concentrations of IFN-beta. Total steroid receptor levels were(More)
Steroid receptor levels were determined in 196 samples of endometrial adenocarcinoma: cytosol estradiol receptors (ERc) were measured in 171 samples, cytosol progesterone receptors (PRc) in all samples; nuclear estradiol receptors (ERn) and nuclear progesterone receptors (PRn) in 68 samples; total estradiol receptors (ERt = ERc plus ERn) and total(More)
The clinical course, the hormone secretion, the testosterone receptors and the enzymatic activities related to androgen metabolism in a 56-year-old postmenopausal woman with a history of virilization and ovarian endometrioma are reported. Unexpectedly, at the time of examination, no evidence of biochemical hyperandrogenism was obtained. The uncommon(More)
The effect of natural beta-interferon (beta-IFN) on steroid receptor levels and output of prostaglandins (PGs) was investigated in human endometrial cancer. beta-IFN determines in endometrial adenocarcinoma explants an increase of cytosolic estradiol (ER) and progesterone (PR) receptors at concentrations ranging from 10 to 1000 IU/ml of culture medium.
