Poteri e riforme nella Sicilia di Carlo di Borbone

2018

The arrival of Charles of Bourbon in Sicily caused great hopes within the “Spanish party” but, at the same time, the fear that the new dynastic unity with Naples would result in the loss of political and military independence of the island. The Giunta per gli Affari di Sicilia (Council for the Affairs of Sicily) should have been a guarantor institution in the Neapolitan perspective, but in reality the Parliament and especially the Deputazione del Regno (Deputation of the kingdom) were the advocates of the Kingdom’s interests. In Sicily the launch of the reforms process was cautious and concentrated on ecclesiastical jurisdiction, without compromising the relationship with the nobles, whose …

BMP7v induces cancer stem cells differentiation and enhances chemotherapy response in colorectal cancer

2014

Cancer stem cells (CSCs), characterized by high levels of ATP-binding cassette, anti-apoptotic molecules, active DNA-repair and slow replication capacities, surviving to conventional anti-cancer therapies, able to eradicate only the highly proliferating tumor cells, represent the elective target for new therapies. Colorectal CSCs (CR-CSCs) represent a powerful tool for preclinical validation of target therapies. In particular the elucidation of the mechanisms that govern stem cell survival and differentiation appears very essential for the identification of new molecular targets in cancer therapy. Among the molecules that govern these processes there are the Bone Morphogenetic Proteins (BMP…

EFFICACY OF ZOLEDRONIC ACID IN PATIENTS WITH RENAL CANCER METASTATIC TO BONE

2011

I in renal cancer patients probably related to survival increase. There are few data in literature about the role of BPs in the treat- ment of bone disease from colorectal cancer. We present the pre- liminary data of a large Italian multicenter retrospective analysis. Methods. 284 renal cancer patients with evidence of bone metastases have been included in the study at the moment of ab- stract submission. Patients characteristics, skeletal related events (SRE) data and median survival after bone metastases appear- ance have been collected in a master data base and statistically analyzed. The primary efficacy endpoint was time to first SRE; secondary endpoint was median survival. Results. A …

Osteoporosis, jawbones and periodontal disease

2012

The association between osteoporosis and jawbones remains an argument of debate. Both osteoporosis and periodontal diseases are bone resorptive diseases; it has been hypothesized that osteoporosis could be a risk factor for the progression of periodontal disease and vice versa. Hypothetical models linking the two conditions exist: in particular, it is supposed that the osteoporosis-related bone mass density reduction may accelerate alveolar bone resorption caused by periodontitis, resulting in a facilitated periodontal bacteria invasion. Invading bacteria, in turn, may alter the normal homeostasis of bone tissue, increasing osteoclastic activity and reducing local and systemic bone density …

Vitamin D Deficiency in HIV Infection: Not Only a Bone Disorder

2015

Hypovitaminosis D is a worldwide disorder, with a high prevalence in the general population of both Western and developing countries. In HIV patients, several studies have linked vitamin D status with bone disease, neurocognitive impairment, depression, cardiovascular disease, high blood pressure, metabolic syndrome, type 2 diabetes mellitus, infections, autoimmune diseases like type 1 diabetes mellitus, and cancer. In this review, we focus on the most recent epidemiological and experimental data dealing with the relationship between vitamin D deficiency and HIV infection. We analysed the extent of the problem, pathogenic mechanisms, clinical implications, and potential benefits of vitamin …

IL RANK LIGANDO QUALE TARGET TERAPEUTICO NEL TRATTAMENTO DELLE PAZIENTI ANZIANE CON OSTEOPOROSI

2013

Cortical and trabecular bone undergo a continuous and balanced remodeling process, which consists of a phase of resorption, mediated by osteoclasts, and a phase of neoformation mediated by osteoblasts. The activity of both, osteoblasts and osteoclasts, is regulated by the osteocytes, which are the most abundant cells in bone tissue. An imbalance of this process with an excessive resorption activity causes a loss of bone mass and microarchitectural deterioration of the skeleton, with consequent reduction of bone strength and increased risk of fractures. The ligand for the “Receptor Activator of Nuclear Factor Kappa- B” (RANK-L), a protein expressed by osteoblasts, plays a fundamental role in…

Magnesium Role in Health and Longevity Final

2018

Reduced Magnesium (Mg intake) is a frequent cause of Mg deficit with age. A decreased intestinal Mg absorption and an increased Mg loss may also contribute, as well as the use of medicaments. Mg requirements may be higher with aging. Alterations of Mg metabolism with age, cellular Mg transport systems and problems with measurement methods are discussed. Mg contained in water is more bio-available than Mg in food and it is a possible alternative to Mg supplementation in the correction of Mg deficiencies. Mild to moderate Mg deficits are generally asymptomatic and clinical signs are usually absent or non-specific. Hyperemotionality, tremor, asthenia, sleep disorders, and amnesic and cognitive…

Italian daily platelet transfusion practice for haematological patients undergoing high dose chemotherapy with or without stem cell transplantation: …

2016

Background. Following high-dose chemotherapy/bone marrow transplantation, patients are routinely, prophylactically transfused with platelet concentrates (PC) if they have a platelet count ≤10×109/L or higher in the presence of risk factors for bleeding. However, whether such transfusions are necessary in clinically stable patients with no bleeding, or whether a therapeutic transfusion strategy could be sufficient and safe, is still debated. Materials and methods. The GIMEMA Haemostasis and Thrombosis Working Party sent a questionnaire to Italian haematology departments to survey several aspects of daily platelet transfusion practice, such as the cut-off platelet count for transfusion, the e…
