Bone mineral density (BMD), the major determinant of osteoporotic fracture risk, has a strong genetic component. The discovery that inactivation of estrogen receptor alpha (ERalpha) gene is associated with low BMD indicated ERalpha as a candidate gene for osteoporosis. We have investigated the role of three ERalpha gene polymorphisms [intron 1 PVU:II and(More)
Osteoporosis is a common skeletal disease characterized by low bone mass and microarchitectural deterioration of bone tissue with a consequent increase in bone fragility and susceptibility to fracture. In the past years, twin and family study have shown that this disease recognizes a strong genetic component and that genetic factors play an important role(More)
BACKGROUND Leiomyomas are the most common tumors in women, found in up to 30% of women in active reproductive life. These tumors are estrogen- and progestin-responsive. In fact, they do not occur before menarche, undergoing rapid increase in size during pregnancy with consequent fetal wastage. Conversely, they can regress or even calcify after menopause or(More)
The potential health consequences of human exposure to environmental estrogen disrupters are not known. Because many chemical compounds are environmentally persistent, toxic and estrogen-active, they can dysregulate the hypothalamic-pituitary-gonadal axis, potentially inducing reproductive disorders such as central precocious puberty (CPP). We performed a(More)
After birth, infant formulas constitute an important or often sole food source for infants during the first months of life. In this study, a survey on the presence of aflatoxin M1 (AFM1) and ochratoxin A (OTA) in the 14 leading brands of infant formulas marketed in Italy was conducted. Mycotoxins were determined by immunoaffinity column clean-up and(More)
Since the 1970s, there has been a worldwide scientific discussion on the potential health consequences of human exposure to endocrine disrupters: many environmentally persistent compounds are oestrogen agonists and/or androgen antagonists. Thus, they can dysregulate the hypothalamic-pituitary-gonadal axis potentially affecting human puberty timing.(More)
Vascular smooth muscle cells (VSMCs) synthesize elastin (ELN), major protein of aortic tunica media which confers strength and elasticity to aortic wall. Protein loss or distortion is typical in aneurysm tunica media. Transforming growth factor beta1 (TGFbeta1) inhibits growth and connective protein expression of abdominal VSMCs cultures. Also, in(More)
OBJECTIVE To test the hypothesis that human puberty timing can be advanced by environmental estrogen exposure. STUDY DESIGN We analyzed serum mycoestrogen contamination via high-performance liquid chromatography (HPLC) in 32 girls affected by central precocious puberty (CPP) and in 31 healthy female control subjects. All 32 patients received triptorelin(More)
OBJECTIVE To explore a possible association between estrogen receptor-alpha (ER-alpha) gene polymorphisms and development of uterine leiomyomas. DESIGN Case-control study. SETTING University teaching hospital. PATIENT(S) 119 women with clinically and surgically diagnosed uterine leiomyomas. INTERVENTION(S) Therapeutic hysterectomy. MAIN OUTCOME(More)
Human milk is, without question, the best source of nutrition for infants containing the optimal balance of fats, carbohydrates and proteins for developing babies. Breastfeeding provides a range of benefits for growth, immunity and development building a powerful bond between mother and her child. Recognition of the manifold benefits of breast milk has led(More)
