Osteoporosis (OMIM166710) is a common skeletal disorder characterized by low bone mass and microarchitectural deterioration of bone tissue with increased susceptibility to fracture. Osteoporosis has a complex etiology and is considered a multifactorial polygenic disease in which genetic determinants are modulated by hormonal, environmental, and nutritional(More)
BACKGROUND The placement of stents in coronary arteries has been shown to reduce restenosis in comparison to balloon angioplasty. However, clinical use of intracoronary stents is impeded by the risk of subacute stent thrombosis and complications associated with the anticoagulant regimen. To reduce these complications, the hypothesis that systemic(More)
Epidemiological studies of Paget's disease of bone (PDB) suggest a pronounced geographical variation in the prevalence of the disease and a decrease in prevalence and clinical severity over time. To analyze epidemiological and clinical features of PDB in Italy, we recently established a registry of Italian PDB cases and performed radiological, biochemical,(More)
BACKGROUND Previous studies have shown that it is feasible to withhold anticoagulation after a successful intracoronary stent procedure with a low incidence of stent thrombosis. The importance of specific antiplatelet agents when stenting is performed without anticoagulation is unknown. METHODS AND RESULTS After successful intravascular ultrasound-guided(More)
Mouse embryonic stem (ES) glucose-6-phosphate (G6P) dehydrogenase-deleted cells ( G6pd delta), obtained by transient Cre recombinase expression in a G6pd -loxed cell line, are unable to produce G6P dehydrogenase (G6PD) protein (EC 1.1.1.42). These G6pd delta cells proliferate in vitro without special requirements but are extremely sensitive to oxidative(More)
Male osteoporosis is an increasingly important health problem. It is known that sex steroid hormones play an important role in regulating bone turnover and bone mass in males as well as in females. However, the exact mechanism of bone loss in men remains unknown. In the present study, 200 elderly men (age range, 55-85 yr) were followed for 4 yr to evaluate(More)
BACKGROUND Treatment of calcified (in contrast to simple) lesions with PTCA has been associated with a lower success rate and more procedural complications. Rotablation can improve acute results, but the high restenosis rate remains a problem. The purpose of this study was to evaluate the clinical and angiographic outcome of patients with complex and(More)
Oxidative stress is caused by imbalance between the production of reactive oxygen species (ROS) and biological system ability to readily detoxify the reactive intermediates or repair the resulting damage. 2-deoxy-D-ribose (dRib) is known to induce apoptosis by provoking an oxidative stress by depleting glutathione (GSH). In this paper, we elucidate the(More)
This study examines the influence of circulating insulin-like growth factor-1 (IGF-1) and serum leptin on bone mass as well as modulation of bone mass during skeletal development. Moreover, an inverse relationship between IGF-1 and leptin is reported. To evaluate the effects of serum IGF-1 and serum leptin on bone mass in healthy postmenopausal women, and(More)
The most frequent muscle hernia of the lower extremities is the anterior tibialis muscle hernia. A number of surgical procedures are available for the treatment of symptomatic anterior tibialis muscle hernias. However, in case of a large fascial defect, their use may be unfeasible or inconvenient. Moreover, current surgical procedures are prone to the risk(More)
