Type V collagen counteracts osteo-differentiation of human mesenchymal stem cells
2014
In search of novel gene signatures for osteo-differentiation of mesenchymal stem cells (MSCs), we submitted cDNA preparations from undifferentiated and differentiating MSCs to differential display- and semiquantitative-PCR and found down-regulation of COL5A1 in osteo-induced cultures at days 21 and 28, when the mineralized matrix accumulates. We also cultured osteo-differentiating MSCs onto type V collagen substrates and found a decrease in the accumulation of extracellular calcium compared to those grown in uncoated flasks. To our knowledge, this is first evidence that type V collagen might represent a stromal component that impairs osteogenesis.
Pathogenesis of polymyalgia rheumatica
2018
Polymyalgia rheumatica (PMR) is a chronic, inflammatory disorder of unknown cause, almost exclusively occurring in people aged over 50 and often associated with giant cell arteritis. The evidence that PMR occurs almost exclusively in individuals aged over 50 may indicate that age-related immune alterations in genetically predisposed subjects contribute to development of the disease. Several infectious agents have been investigated as possible triggers of PMR even though the results are inconclusive. Activation of the innate and adaptive immune systems has been proved in PMR patients as demonstrated by the activation of dendritic cells and monocytes/macrophages and the altered balance betwee…
Fysioterapeuters erfaringer med bruk av fysisk aktivitet til eldre deprimerte
2015
This article is based upon a study of the experiences of physiotherapists working with elderly depressed patients and the use of physical activity. Depression in the elderly is a common condition, and it is estimated to be the second most common cause of failing health towards 2020. Physical activity has a positive effect on depression in the elderly. The aim of this study was to investigate the experiences of physiotherapist`s in the treatment of elderly depressed patients over 65 years of age. Data was collected by qualitative reasearch interviews of 5 physiotherapists. Important findings of this study were that the physiotherapists experienced that they did not get any referrals to treat…
Changes in spinal range of motion after a flexibility training program in elderly women
2014
Giuseppe Battaglia,1,2 Marianna Bellafiore,1,2 Giovanni Caramazza,2 Antonio Paoli,3 Antonino Bianco,1,2 Antonio Palma1,2 1Department of Law, Society, and Sport Sciences, University of Palermo, Palermo, Italy; 2Sicilian Regional Sports School of Italian National Olympic Committee (CONI), Sicily, Italy; 3Department of Biomedical Sciences, University of Padova, Padova, Italy Background: Aging-related reduced spinal mobility can interfere with the execution of important functional skills and activities in elderly women. Although several studies have shown positive outcomes in response to spinal flexibility training programs, little is known about the management of sets and repetitions in traini…
Extracellular matrix regulation of PTHrP and PTH/PTHrP receptor in a human breast cancer cell line
1999
AbstractIt was previously reported that 8701-BC breast cancer cells express the gene for parathyroid hormone-related peptide (PTHrP) and its cognate receptor (PTHrP-R), and release immunoreactive PTHrP in the extracellular medium; it was also found that PTHrP, in turn, exerts a role on the proliferative and invasive behavior in vitro of the same cell line. On the other hand, evidence has been produced that adhesion of 8701-BC cells onto different collagen substrates influences in various ways a number of phenotypic expressions, such as cell growth, motility, invasion of reconstituted basement membrane and production of lytic enzymes of the extracellular matrix (ECM). In light of these previ…
Abatacept as Adjunctive Therapy in Refractory Polymyalgia Rheumatica.
2021
Glucocorticoids (GCs) are the mainstay of treatment for patients with polymyalgia rheumatica (PMR).1 Despite their efficacy, GCs are associated with well-known adverse events and a substantial proportion of patients with PMR do not respond adequately, or are refractory, to initial GC treatment. GC-sparing agents in PMR are limited to methotrexate (MTX).1.
Remembering and Forgetting, Discovering and Cherishing : Engagements with material culture of war in Finnish Lapland
2018
The Second World War left considerable material remains in Finnish Lapland, ranging from remnants of structures destroyed in the 1944–45 Lapland War, through to small artefacts connected to soldiers, prisoners of war and civilians. These material remains have variously been saved and cherished by survivors and their families, forgotten or disregarded as ‘war junk’, ‘discovered’ by hobbyists, amassed and exchanged by private collectors, and/or accessioned into official museum collections. These various processes represent engagements with material culture of war that take on various meanings and embodiments, depending on the different individuals and organizations involved.We have conducted …
Successful approaches to mental practice : A case study of four pianists
2019
Musicians often use mental practice for enhancing performance, but individuals may have different preferences and skills in their characteristic, individually successful ways of carrying out such practice. In this study, we focus on the approaches to mental practice of four pianists who, according to the ratings of a panel of expert judges, showed outstanding improvement in their performances following their mental practice of a new piece in at least one of the two conditions: silent reading of the score or reading the score while simultaneously listening to the music. The four pianists’ approaches to mental practice were studied through self-reports in post-task interviews that were compar…
Fourth case of louse-borne relapsing fever in Young Migrant, Sicily, Italy, December 2015. Mini Review Article
2016
Abstract Objectives Currently louse-borne relapsing fever (LBRF) is primarily found in limited endemic foci in Ethiopia, Somalia and Sudan; no case of imported LBRF has been reported in Europe in the 9 years prior to 2015. The aim of our paper is to describe a new case of imported LBRF detected in Sicily, Italy, and to review all cases reported in migrants arrived in Europe in the last 10 years. Study design Mini review of all published cases of louse-borne relapsing fever in Europe in the last 10 years. Methods A computerized search without language restriction was conducted using PubMed combining the terms ‘(louse-borne relapsing fever or LBRF or recurrentis) and (refugee or Europe or mig…
Effects of Coenzyme Q10 on Statin-Induced Myopathy
2015
Abstract Objective To evaluate the efficacy of coenzyme Q10 (CoQ10) supplementation on statin-induced myopathy. Participants and Methods We searched the MEDLINE, Cochrane Library, Scopus, and EMBASE databases (November 1, 1987, to May 1, 2014) to identify randomized controlled trials investigating the impact of CoQ10 on muscle pain and plasma creatine kinase (CK) activity as 2 measures of statin-induced myalgia. Two independent reviewers extracted data on study characteristics, methods, and outcomes. Results We included 6 studies with 302 patients receiving statin therapy: 5 studies with 226 participants evaluated the effect of CoQ10 supplementation on plasma CK activity, and 5 studies (4 u…
