PLAYING-RELATED MUSCULOSKELETAL DISORDERS IN WOODWIND, BRASS AND PERCUSSION PLAYERS: A REVIEW

2010

Performing Arts Medicine is a broad field that includes the study of medical conditions and injuries incurred by dancers, instrument musicians and vocalists. Musicians' playing-related health problems have focused more and more the interest of scientists, researchers, physicians, physiotherapists and, in generally, of health care professionals during the last decades. The most relevant Performing Arts Medicine's literature of approximately the past twenty years has been summarized. Special attention has been given to studies concerning playing-related musculoskeletal conditions of musicians. Overuse syndrome is the most reported diagnosis among instrumental musicians suffering from playing-…

Analysis of molecular mechanisms and anti-tumoural effects of zoledronic acid in breast cancer cells

2012

Zoledronic acid (ZOL) is the most potent nitrogen-containing bisphosphonate (N-BPs) that strongly binds to bone mineral and acts as a powerful inhibitor of bone resorption, already clinically available for the treatment of patients with osteolytic metastases. Recent data also suggest that ZOL, used in breast cancer, may provide more than just supportive care modifying the course of the disease, though the possible molecular mechanism of action is still unclear. As breast cancer is one of the primary tumours with high propensity to metastasize to the bone, we investigated, for the first time, differential gene expression profile on Michigan Cancer Foundation-7 (MCF-7) breast cancer cells tre…

Control of murine hair follicle regression (catagen) by TGF‐β1in vivo

2000

The regression phase of the hair cycle (catagen) is an apoptosis-driven process accompanied by terminal differentiation, proteolysis, and matrix remodeling. As an inhibitor of keratinocyte proliferation and inductor of keratinocyte apoptosis, transforming growth factor beta1 (TGF-beta1) has been proposed to play an important role in catagen regulation. This is suggested, for example, by maximal expression of TGF-beta1 and its receptors during late anagen and the onset of catagen of the hair cycle. We examined the potential involvement of TGF-beta1 in catagen control. We compared the first spontaneous entry of hair follicles into catagen between TGF-beta1 null mice and age-matched wild-type …

Human Prostate Cancer: A Direct Role for Oestrogens

2007

We have studied the response to oestrogen and expression of oestrogen receptors in responsive LNCaP and androgen non-responsive PC3 human prostate cancer cell lines. Growth of LNCaP cells is significantly stimulated by physiological concentrations of oestradiol; this growth increase appears to be comparable to that induced by either testosterone or dihydrotestosterone. In contrast, oestradiol significantly inhibits the proliferation of PC3 cells. We also present novel evidence for functional oestrogen binding in LNCaP cells. This evidence was first obtained by means of radioligand binding assays and was further corroborated using: (a) immunocytochemical analysis of oestrogen and progesteron…

Thrombosis and thromboembolism related to COVID‐19: A clarion call for obtaining solid estimates from large‐scale multicenter data

2020

Abstract The clinical spectrum of coronavirus disease 2019 (COVID‐19) is wide, ranging from minor, nonspecific symptoms to severe pneumonia, acute respiratory distress syndrome, multiorgan involvement, and shock. In severe cases, the acute systemic inflammatory response, coagulation activation, and diffuse endothelial damage may, in combination with hypoxia, immobilization, and underlying risk factors, result in potentially life‐threatening venous and arterial thrombotic events. The first data from single‐center retrospective studies suggest that thrombotic events are a key aspect of COVID‐19‐associated morbidity and mortality. We have planned and will be launching the COvid REgistry on THR…

CARDIOVASCULAR RISK IN ESSENTIAL THROMBOCYTHEMIA AND POLYCYTHEMIA VERA: THROMBOTIC RISK AND SURVIVAL

2019

Thromboembolic and bleeding events pose a severe risk for patients with Polycythemia Vera (PV) and Essential Thrombocythemia (ET). Many factors can contribute to promoting the thrombotic event due to the interaction between platelets, leukocytes, and endothelium alterations. Moreover, a significant role can be played by cardiovascular risk factors (CV.R) such as cigarette smoking habits, hypertension, diabetes, obesity and dyslipidemia. In this study, we evaluated the impact that CV.R plays on thrombotic risk and survival in patients with PV and ET .

Using pharmacokinetics for tailoring prophylaxis in people with hemophilia switching between clotting factor products: A scoping review.

2019

Abstract The objective of this scoping review is to summarize the current use of pharmacokinetics for tailoring prophylaxis in hemophilia patients switching between clotting factor products. Patients with hemophilia may require switching of clotting factor concentrates due to a variety of factors, but there have been perceived risks associated with switching, such as inhibitor development or suboptimal protection due to inadequate dosing while titrating treatment. Studies that look at patients switching from one clotting factor concentrate to another are categorized in terms of their primary and/or secondary objectives, notably biosimilarity and comparative pharmacokinetic studies and inhib…

Developmental and tumoral vascularization is regulated by G protein-coupled receptor kinase 2

2012

Tumor vessel dysfunction is a pivotal event in cancer progression. Using an in vivo neovascularization model, we identified G protein–coupled receptor kinase 2 (GRK2) as a key angiogenesis regulator. An impaired angiogenic response involving immature vessels was observed in mice hemizygous for Grk2 or in animals with endothelium-specific Grk2 silencing. ECs isolated from these animals displayed intrinsic alterations in migration, TGF-β signaling, and formation of tubular networks. Remarkably, an altered pattern of vessel growth and maturation was detected in postnatal retinas from endothelium-specific Grk2 knockout animals. Mouse embryos with systemic or endothelium-selective Grk2 ablation …

Sinusoidal endothelial liver cells in vitro release endothelin — Augmentation by transforming growth factorβ and Kupffer cell-conditioned media

1991

Endothelin is the most potent vasoconstrictor peptide known today. Using a radioimmunoassay for endothelin, we measured immunoreactive endothelin in culture media of guinea pig sinusoidal endothelial liver cells and human umbilical vein endothelial cells. A time-dependent release of immunoreactive endothelin by confluent sinusoidal endothelial liver cells in culture was found. Sinusoidal endothelial liver cells produced similar amounts of immunoreactive endothelin as umbilical vein endothelial cells, about 900 pg/microgram DNA per 24 h. In the presence of transforming growth factor beta a dose-dependent increase of immunoreactive endothelin release was measured. The maximal increase of 50% …
