Substance P (SP) and calcitonin gene-related peptide (CGRP) have been found in the perichondrium and within the cartilage canals. It is still unknown whether they exert a direct effect on chondrocytes during joint development. We processed 28 knees of newborn Wistar rats in 7 different fashions to perform histology and immunohistochemistry studies. Positive(More)
PURPOSE It is known that participating in sports can have a beneficial effect on bone mass. However, it is not well established which sport is more beneficial for increased bone mineral density (BMD) and appendicular muscle mass (AMM). This study investigated the effects of different high-intensity activities on BMD and AMM in highly trained athletes. (More)
Osteoarthritis is a progressive joint disease characterized by cartilage degradation and bone remodelling. Under physiologic conditions, articular cartilage displays a stable chondrocyte phenotype, whereas in osteoarthritis a chondrocyte hypertrophy develops near the sites of cartilage surface damage and associates to the pathologic expression of type X(More)
INTRODUCTION We aimed to assess the incidence and hospitalization rate of hip and "minor" fragility fractures in the Italian population. METHODS We carried out a 3-year survey at 10 major Italian emergency departments to evaluate the hospitalization rate of hip, forearm, humeral, ankle, and vertebral fragility fractures in people 45 years or older between(More)
UNLABELLED We demonstrated that osteoporosis is associated with a preferential type II muscle fiber atrophy, which correlates with bone mineral density and reduced levels of Akt, a major regulator of muscle mass. In osteoarthritis, muscle atrophy is of lower extent and related to disease duration and severity. INTRODUCTION Osteoarthritis (OA) and(More)
Osteoporosis (OP) and osteoarthritis (OA) are the most common joint diseases, with a high incidence in the elderly population. OP is characterized by trabecular bone remodeling and reabsorption, whereas articular cartilage and subchondral bone remodeling are major features of OA. Although classically considered as independent or even conflicting processes,(More)
Introduction There are several factors influencing the fracture healing process, the most important being age and bone quality. Cellular and molecular alterations that can be found in elderly patients make the healing process difficult, and may lead to complications such as pseudoarthro-sis or delayed non-union. In the same way, in altered bone metabolism(More)
Apoptosis can occur throughout the life span of osteoblasts (OBs), beginning from the early stages of differentiation and continuing throughout all stages of their working life. Here, we investigated the effects of tumor necrosis factor (TNF)-related apoptosis-inducing ligand (TRAIL) on normal human OBs showing for the first time that the expression of(More)
Osteoporotic fractures remain a major public health problem for their correlated morbidity and mortality. The primary aim of therapy must be the prevention of the first fragility fracture and avoiding subsequent fractures in patients who already have an existing fracture. There are evidences from randomized controlled trials (RCTs) about the efficacy of(More)
BACKGROUND Reduction of tibial plateau fractures and maintain a level of well aligned congruent joint is key to a satisfactory clinical outcome and is important for the return to pre-trauma level of activity. Stable internal fixation support early mobility and weight bearing. The augmentation with bone graft substitute is often required to support the(More)
