Leisure activities and well-being in midlife and older age with special reference to physical activity and resistance training
2019
Participation in leisure activities is related to better well-being. Participation in leisure time physical activity also has several positive effects on functional capacity and health. Notwithstanding, only a minor proportion of adults, including older adults, participate in physical activity at a sufficient level for maintaining or improving their health. This study investigated both cross- sectional and longitudinal associations between different types of leisure and physical activities and well-being. This dissertation is based on data from three research projects: the Finland 2014 – Consumption and Lifestyle postal survey, conducted with a random sample representative of the Finnish ad…
Deception and abuse: Manifold Instances of Proxemic Violence against Sub-Saharan and Eastern-European Women-Immigrants In Sicily
2019
Over the past few decades and up until 2017, Sicily has hosted increasing numbers of African fugitives (ANCI et al., 2017) as well as migrants from Eastern Europe, especially after the entry of Romania into the European Union. The aim of the research was to analyse some of the role positions found in gender dynamics among migrants, throwing light on possible processes by which mechanisms of submission to and normalisation of gender based violence seem to have been internalised by these victims of proximity violence, emphasising the viscous links existing between vulnerability, resistance and resilience. Within this markedly multicultural context in Sicily, the researchers carried out a two-…
Greater mitochondrial energy production provides resistance to ocean acidification in "winning" hermatypic corals
2021
Coral communities around the world are projected to be negatively affected by ocean acidification. Not all coral species will respond in the same manner to rising CO2 levels. Evidence from naturally acidified areas such as CO2 seeps have shown that although a few species are resistant to elevated CO2, most lack sufficient resistance resulting in their decline. This has led to the simple grouping of coral species into “winners” and “losers,” but the physiological traits supporting this ecological assessment are yet to be fully understood. Here using CO2 seeps, in two biogeographically distinct regions, we investigated whether physiological traits related to energy production [mitochondrial e…
Molecular Spintronic Devices: from Molecular Spin Valves to Spin-OLEDs
2017
La investigación llevada a cabo durante el periodo de tesis doctoral y que se describe en este manuscrito pertenece al campo de la espintrónica molecular. Ha sido motivada por el deseo de incorporar nuevos materiales moleculares a dispositivos espintrónicos y ahondar en la comprensión de la inyección y el transporte de espín en este tipo de capas, a través del estudio de dispositivos como la válvula de espín molecular y el spin-OLED. En 1988 Albert Fert y Peter Grünberg descubrieron que la resistencia eléctrica de unas multicapas de Fe-Cr variaba considerablemente en función de la magnetización de las láminas. El efecto se conoce hoy en día como magnetoresistencia gigante o GMR, por sus sig…
Mycobacterium tuberculosis multirezistences noteikšana
2018
Latvijā un pasaulē joprojām mirst no ārstējamas slimības – tuberkuloze ir devītais nāves cēlonis pasaulē. Nozīmīga sabiedrības veselības problēma ir M. tuberculosis multirezistence pret antibakteriālajiem līdzekļiem. Rezistence pret antibakteriālajiem līdzekļiem galvenokārt saistīta ar to, ka daļa tuberkulozes slimnieku netiek savlaicīgi atklāti, tādējādi turpinot slimības aktīvu transmisiju sabiedrībā; antibakteriālo līdzekļu nepareizu pielietošanu – priekšlaicīgi pārtrauc terapiju vai lieto zāles neregulāri, kā rezultātā rodas multirezistentās tuberkulozes formas. Darba mērķis: Noteikt no klīniskā materiāla izdalīto M. tuberculosis celmu sastopamības biežumu un to rezistenci pret antibakt…
Effects of resistance training frequency on muscle strength, activity and mass during a 24-week intervention in the elderly
2016
Elderly populations are increasingly affected by sarcopenia, dynapenia and osteoporosis. They all increase frailty and decrease quality of life and life-expectancy. Resistance training (RT) has been reported extensively as a tool that can prevent, counter and in some cases reverse the course of the abovementioned diseases. Several studies covering RT adaptations in elderly populations have investigated periods between 6 up to 88 weeks with different frequencies, from 1 to 3 trainings / week and a wide range of intensities (30-85% or one repetition maximum) and different volumes. The aim of this study was to investigate the effect of different training frequencies (one, two or three times / …
Case series of fluoroscopic findings and 3D reconstruction of human spinal MRIs of the space of Okada.
2020
Objective To better understand the unexpected spread of contrast medium observed by conventional fluoroscopic X-ray images during standard neuraxial techniques used in the treatment of pain. The support of 3D reconstruction of MRI images of structures within the lumbar spine was used to better understand the space of Okada. Methods Lumbar facet joint and epidural corticosteroid injections in five patients under fluoroscopic guidance with loss of resistance to air or saline to identify the facet joints or epidural space. Next, in a retrospective study, the authors examined the retrodural space of Okada and the neighboring tissues with 3D reconstruction of spinal MRIs of seven patients withou…
Comparison of frictional resistance between passive self-ligating brackets and slide-type low-friction ligature brackets during the alignment and lev…
2019
Background To compare the frictional resistance between passive self-ligating brackets and conventional brackets with low-friction ligature under bracket/archwire and root/bone interface during dental alignment and leveling. Material and methods A tridimensional model of the maxilla and teeth of a patient treated with conventional brackets, and slide ligatures was generated employing the SolidWorks modeling software. SmartClip self-ligating brackets and Logic Line conventional brackets were assembled with slide low-friction ligatures, utilizing archwires with different diameters and alloys used for the alignment and leveling stage. Friction caused during the bracket/archwire interface and s…
New Modalities in Knee Osteoarthritis Treatment Using Autologous Bone Marrow-Derived Mononuclear Cells
2018
Abstract The clinical effects on knee osteoarthritis (OA) symptoms and tissue structure were evaluated after bone marrow-derived mononuclear cell intraarticular injection. A group of 32 patients with 34 knee joints in stage II–III osteoarthritis were treated by intraarticular injection of mononuclear cell suspension. Clinical results were obtained by KOOS (Knee Osteoarthritis Outcome Score) and KSS (Knee Society Score) scores during a 12 months follow-up period. Radiological evaluation was performed using magnetic resonance imaging. A comparison with a control group of 28 patients treated with routinely used three hyaluronic acid intra-articular injections was made. No adverse effects were …
An update on the relationships between rheumatoid arthritis and atherosclerosis
2010
Rheumatoid arthritis is a chronic inflammatory disease. Cardiovascular events are the most important cause of mortality and morbidity in patients with rheumatoid arthritis. Beyond the traditional cardiovascular risk factors, chronic systemic inflammation has been shown to be a crucial factor in atherosclerosis development and progression from endothelial dysfunction to plaque rupture and thrombosis. Many studies have shown that atherosclerosis is not a passive event like accumulation of lipids in the vessel walls; by contrast, it represents an active inflammation of the vessels. Inflammatory cells such as macrophages, monocytes and T cells play important roles in the development of both rhe…
