Oxidation-Induced Increase In Photoreactivity of Bovine Retinal Lipid Extract

2017

Open access original paper Source : 10th EPR Workshop on Applications of EPR in Biology and Medicine, 2016 in Krakow, POLAND.; International audience; The mammalian retina contains a high level of polyunsaturated fatty acids, including docosahexaenoic acid (22:6) (DHA), which are highly susceptible to oxidation. It has been shown that one of the products of DHA oxidation-carboxyethylpyrrole (CEP), generated in situ, causes modifications of retinal proteins and induces inflammation response in the outer retina. These contributing factors may play a role in the development of age-related macular degeneration (AMD). It is also possible that some of the lipid oxidation products are photoreactiv…

Mass, phylogeny, and temperature are sufficient to explain differences in metabolic scaling across mammalian orders?

2016

Abstract Whether basal metabolic rate‐body mass scaling relationships have a single exponent is highly discussed, and also the correct statistical model to establish relationships. Here, we aimed (1) to identify statistically best scaling models for 17 mammalian orders, Marsupialia, Eutheria and all mammals, and (2) thereby to prove whether correcting for differences in species’ body temperature and their shared evolutionary history improves models and their biological interpretability. We used the large dataset from Sieg et al. (The American Naturalist 174, 2009, 720) providing species’ body mass (BM), basal metabolic rate (BMR) and body temperature (T). We applied different statistical ap…

Assessment of Muscular Fitness as a Predictor of Flight Duty Limitation.

2018

Introduction The high acceleration (Gz) exposure among military pilots flying fighter aircraft has been associated with an increased risk for cervical and lumbar disorders. It has been suggested that an adequate level of physical performance could reduce the risk of experiencing these disorders. The Finnish Air Force has for several years used aerobic (bicycle ergometer) and muscular fitness tests (battery of five tests) in the selection process of military pilot candidates in order to evaluate their physical fitness level. The aim of the study was to determine if these selection phase tests and anthropometry measures can predispose those individuals who might be at risk of developing sever…

Elements of biomechanics correlated to the body mass index in knee osteoarthritis

2020

Introduction. Osteoarthritis is considered a complex biopsychosocial condition, with consequences for the patient, the family, society and public health. Age is considered the main risk factor in the occurrence of osteoarthritis. Studies show that 2 out of 3 obese individuals associate knee osteoarthritis whereas the incidence of the latter increases at the same time with increasing body mass index. Obesity contributes to the initiation of the process of osteoarthritis by the mechanical overload of the joint, causing cartilage damage with increasing horizontal cracks and the increased incidence of the osteophites in the knee. Purpose. We conducted a study in patients with knee osteoarthriti…

Physical capacity in performing daily activities is reduced in scleroderma patients with early lung involvement

2015

Background and Aims Patients with systemic sclerosis (SSc) often complain reduced capacity at submaximal exercise; conversely, physical capacity in performing daily duties has never been measured in SSc. The aim of this study is to evaluate this performance and its correlates, in patients with SSc compared with healthy controls, in a free-living setting. Methods Twenty-seven outpatients with stable SSc and 11 controls were recruited. Physical activity was assessed by portable multiple sensor device (SenseWear Armband) worn for at least 6 days. Physical activity duration (PAD; in minutes) for non-sedentary activities and physical activity level (PAL = total daily energy/resting energy expend…

The Impact of Body Mass Index on Disease Progression in Ankylosing Spondylitis

2018

Abstract Obesity can be a factor that affects the course of chronic systemic inflammatory arthritis. The objective of this study was to characterise patients with ankylosing spondylitis (AS) according to an evaluation of their body mass index (BMI) and by exploring the link between the overweightness and obesity with routinely measured disease-specific variables, including disease activity (Bath Ankylosing Spondylitis Disease Activity Index BASDAI; Ankylosing Spondylitis Disease Activity Score, using CRP, ASDAScrp), spinal mobility (Bath Ankylosing Spondylitis Metrology Index, BASMI), functional capacity (BASFI), extraspinal manifestations like fatigue, uveitis, and peripheral arthritis pre…

Level of 25-Hydroxyvitamin D in Pediatric Arthritis Patients

2019

Abstract Vitamin D deficiency is common and widespread globally. Vitamin D has an immunomodulatory effect, but it is still unclear whether its deficiency is associated with higher disease activity. The aim of this retrospective study was to determine the serum concentration of vitamin D in children with paediatric arthritis (juvenile idiopathic arthritis and reactive arthritis). Prevalence of hypo-vitaminosis D among 98 children with juvenile idiopathic arthritis and reactive arthritis was determined and association between serum concentration of vitamin D and disease activity markers was found. Prevalence of vitamin D deficiency among children included in this study was 69.07%. Children wi…

Efficacy of Tailored Exercise Therapy on Physical Functioning in Patients With Knee Osteoarthritis and Comorbidity: A Randomized Controlled Trial

2017

Objective: To evaluate the efficacy on physical functioning and safety of tailored exercise therapy in patients with knee osteoarthritis (OA) and comorbidities. Methods: In a randomized controlled trial, 126 participants were included with a clinical diagnosis of knee OA and at least 1 of the following target comorbidities: coronary disease, heart failure, type 2 diabetes mellitus, chronic obstructive pulmonary disease, or obesity (body mass index ≥30 kg/m2), with severity score ≥2 on the Cumulative Illness Rating Scale. The intervention group received a 20-week, individualized, comorbidity-adapted exercise program consisting of aerobic and strength training and training of daily activities…

Paving the way for synthetic biology-based bioremediation in Europe

2009

Synthetic biology (SB) has a dual definition. It is both the design and construction of new biological parts, devices and systems, and also the re‐design of existing, natural systems for useful purposes. The latter field is maybe one of the major challenges within this discipline, since the promising prospect that biological systems may be used as biomachines will certainly be exploited in the near future. Synthetic biology has challenging conceptual possibilities (Moya et al., 2009a) and impressive progress has already been made in biotechnology following SB approaches (de Lorenzo and Danchin, 2008). Much more is expected in the near future from current efforts aiming to make synthetic gen…
