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)
BACKGROUND Skeletal characteristics such as height (Ht), bone mineral density (BMD) or bone turnover markers are strongly inherited. Common variants in the genes encoding for estrogen receptor alpha (ESR1) and beta (ESR2) are proposed as candidates for influencing bone phenotypes at the population level. METHODS We studied 641 healthy premenopausal women(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)
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)
Hypochondroplasia (HCH) is a genetic skeletal dysplasia, characterized by rhizomelic short height (Ht) with facial dysmorphology and lumbar hyperlordosis. Albeit there are concerns that HCH children may not achieve optimal long-term outcome in response to recombinant human growth hormone (rhGH), anecdotal experiences suggested at least short-term Ht(More)
BACKGROUND Carotid intima-media thickness (IMT), indices of large artery stiffness and measures of endothelium function may be used as markers of early atherosclerosis in type 1 diabetes mellitus (T1DM). The aim of the present study was to compare the indices of large artery structure and function as well as endothelial function and regenerating capacity(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)
