OBJECTIVES The association of bone turnover markers (BTM) with bone loss and fracture risk in men is poorly studied. The morphological basis of such a relationship is unknown. The objective of this study was to evaluate the association between baseline BTM levels and subsequent bone loss and fracture risk in men. METHODS This study is a prospective(More)
The aim of the research was to evaluate a heavy metal, Cadmium (Cd), which was used to produce alterations in human breast cancer cell line MCF-7. Moreover, we analyzed both immunohistochemical and ultrastructural alterations induced by the antineoplastic drug, 5-Fluorouracil (5-FU), after exposure to different concentrations of Cadmium. Also, we compared(More)
INTRODUCTION The present study was initiated to investigate the cadmium concentrations in whole blood of Northern Sardinian, non-occupationally exposed adult subjects. Sardinia is a large Italian island which differs genetically and environmentally from other mainland Italian areas. METHODS Two hundred and forty-three adults (157 females and 86 males)(More)
The different components of the benthic community of a sandy microtidal beach (Arenzano) in Liguria (NW Mediterranean) were investigated during late spring (May) 2002 and 2003. Sampling was carried out in two transects, chosen in order to represent the characteristics of the entire beach and their eventual spatial variations. Each transect included two(More)
The number, position, structural and ultrastructural features of the flexor tendon pulley system in six human embryonic hands, aged from 6 to 12 weeks, were studied by light and electron microscope. The pulley system can be recognized from the ninth week; later, at 12 weeks, the structures are easily identified around the flexor tendon in positions closely(More)
Bone collagen has a specific molecular ultrastructure which can be proved by birefringence. This protein, forming the main organic component of bone tissue, is known to survive millennia in paleontological bones and teeth. Birefringence of bone collagen obtained from the skeletons of the Nuraghi population living in Sardinia c-ca 1500 years B.C. was found(More)
Seamounts and their influence on the surrounding environment are currently being extensively debated but, surprisingly, scant information is available for the Mediterranean area. Furthermore, although the deep Tyrrhenian Sea is characterised by a complex bottom morphology and peculiar hydrodynamic features, which would suggest a variable influence on the(More)
Unbalanced whole-arm translocations (WATs) of the long arm of chromosome 1, resulting in complete trisomy 1q, are chromosomal abnormalities detectable in both solid tumors and hematologic neoplasms. Among the WATs of 1q to acrocentric chromosomes, a few patients with der(1;15) described as a dicentric chromosome have been reported so far, whereas cases of(More)
Calculus may be considered as an aggregate of calcified deposits or deposits that are going to calcify in the oral cavity. From a topographical point of view calculus is classified in supragingival and subgingival calculus. Calculus is composed by inorganic (70-80%) and organic (20-30%) components. Calculus results from calcification of plaque and(More)
The evaluation of the volume of the encephalic ventricles in the living human has a great importance in diagnosis and monitoring of several pathologies. As well as a good measuring accuracy, a great usefulness has the facility of execution. The present study would be a contribution to the search of systems of analysis that assure both fast execution and(More)
