Genetic hyperhomocysteinemia is associated with skeletal abnormalities and osteoporosis. We tested whether levels of homocysteine and critical co-enzymes of homocysteine metabolism, such as vitamin B12 and folate, are related to lumbar spine bone mineral density (BMD) measured by DEXA in 161 postmenopausal women. Folate but not homocysteine or vitamin B12,(More)
BACKGROUND Controlled-rate freezing of ovarian cortical tissue for preservation of fertility among young women facing chemo- or radio-therapy is a widely accepted procedure. To improve the method for cryopreservation of ovarian tissue, particularly the stroma, we carried out a systematic comparison of vitrification versus slow programmed freezing. METHODS(More)
BACKGROUND Anti-Müllerian hormone (AMH) is member of the transforming growth factor-beta superfamily of growth factors. AMH is detected in serum from women of reproductive age and its levels vary slightly with the menstrual cycle, reaching the peak value in the late follicular phase. The present study was undertaken to assess the effect of controlled(More)
OBJECTIVE The objectives of this study were: (1) to determine anti-Mullerian hormone (AMH) levels in menopausal women, and (2) to confirm the source of AMH in cycling women and its disappearance after the removal of the source. METHODS An observational and prospective study was conducted. RESULTS A total of 47 women were recruited for the study. The(More)
OBJECTIVE To investigate a possible correlation between interleukin-12 (IL-12) and IL-13 levels and lymphocyte subsets in the preovulatory follicles of patients with and without polycystic ovarian syndrome (PCOS). DESIGN Controlled clinical study. SETTING University hospital. PATIENT(S) Seventy-eight infertile women undergoing IVF-embryo transfer. (More)
Anti-müllerian hormone (AMH) appears to regulate follicular growth. The aim of this study was to investigate AMH serum levels in patients affected by secondary amenorrhea. The AMH was significantly lower (or undetectable) in patients with premature ovarian failure (POF) and significantly higher in patients affected by polycystic ovary syndrome (PCOS). We(More)
BACKGROUND The nocturnal decline of blood pressure (BP) is almost coincident with the elevation of melatonin, which may exert vasodilatating and hypotensive effects. In this study we investigated whether prolonged nocturnal administration of melatonin could influence the daily rhythm of BP in women. METHODS In a randomized double-blind study, 18 women, 47(More)
The aim of the present study was to examine the relationship between Mullerian-inhibiting substance (MIS) levels and metabolic characteristics in women with polycystic ovary syndrome. Increased ovarian MIS production may exert a paracrine negative control on follicle growth sufficiently to prevent selection of a dominant follicle.
OBJECTIVES We assessed fetal heart variability and activity using a computerized non-stress test (NST) during acupuncture plus moxibustion on the BL67 point. For comparison, the same changes were assessed during placebo acupuncture (minimal acupuncture) in the same subjects. METHODS Twelve pregnant women in the 33rd week of gestation, carrying singletons(More)
OBJECTIVE Vasomotor symptoms may increase the risk for cardiovascular diseases through still elusive mechanisms. Increased cortisol release may favor atherosclerosis. In this study, we tested whether vasomotor and psychological symptoms are associated with an increase in cortisol levels. METHODS A cross-sectional investigation on women in early menopause(More)
