Lipid peroxidation capacities in the myocardium of endurance-trained rats and mice in vitro.
1992
The endurance-training programme in Experiment 1 (Exp. 1) consisted of a total swimming time of 149–159 h per male Han Wistar rat and in Experiment 2 (Exp. 2) the male NMRI-mice run on a treadmill at a speed of 25 m min-1 1 h per day, 5 days a week for 3 weeks. One group of the rat hearts was perfused with 0.3 mm cumene hydroperoxide (CumOOH) while the others were fractioned (mitochondria, sarcolemma and sarcoplasmic reticulum) and these cell fractions and homogenates were used to determine the total concentration of peroxidative lipids and the susceptibility to lipid peroxidation. The perfusion with CumOOH caused the release of thiobarbituric acid reactive substances (TBARS) into the perfu…
Inter-relationship between platelet-derived microparticles and oxidative stress in patients with venous thromboembolism
2020
Background: Hypercoagulative conditions play a key role in venous thromboembolism (VTE). Inflammation is currently linked to VTE, but the potential role of circulating microparticles and oxidative stress (OxS) must be elucidated. The aim of this study was to evaluate platelet-derived microparticles and surrogate OxS biomarkers in patients diagnosed with VTE through a case&ndash
Interferon decreases serum lipid peroxidation products of hepatitis C patients
1994
Abstract Thiobarbituric acid reactive substances (TBARS) concentration in serum has been determined in healthy subjects and in patients suffering acute hepatitis and chronic cases of hepatitis C. Treatment with interferon of the chronic active hepatitis C patients, 5 × 10 6 U three times a week during 2 months, led in those patients whose SGPT activity normalized in serum, to a concomitant decrease in serum TBARS content. The possible theoretical involvement of peroxidation and antioxidants in this beneficial effect of interferon in hepatitis C patients is discussed. The results presented confirm the value of TBARS as laboratory test in the management of liver diseases and as a useful tool …
Interrelationships between oxidative stress and MMP-9 in subjects with severe obstructive sleep apnea syndrome
2016
Obstructive sleep apnea syndrome (OSAS) is significantly and independently associated with an increased risk of cardiovascular diseases, cerebrovascular events and all-cause mortality and some studies have demonstrated that the incidence of cardiovascular events is related to its severity. Our aim was to examine the oxidative status and the matrix metalloproteases (MMP) profile in a group of subjects with OSAS. We enrolled 48 subjects with OSAS, defined after a 1-night cardiorespiratory sleep study, which were subsequently subdivided in two subgroups according to the severity of OSAS: mild-moderate OSAS = “Low”, severe OSAS = “High”. We measured the parameters of oxidative stress, such as l…
FRP reinforcement for concrete structures: state-of-the-art review of application and design
2014
Fiber reinforced polymers (FRPs) are considered to be a promising alternative to steel reinforcement, especially in concrete structures subjected to an aggressive environment or to the effects of electromagnetic fields. Although attempts to develop effective reinforcement have been followed, the application of FRPs remains limited by the solution to simple structural problems that mainly appear due to the absence of design codes, significant variation in the material properties of FRP composites and limited knowledge gained by engineers as regards the application aspects of FRP composites and structural mechanics of concrete elements reinforced with FRPs. To fill the latter gap, the current…
Les coopérations de proximité dans l'Arc jurassien franco-suisse : Un enjeu de la cohésion sociale transfrontalière
2017
Un certain nombre de coopérations s’établissent plus ou moins spontanément de part et d’autre de la frontière franco-suisse dans l’Arc jurassien. En général de petite taille, visibles ou non aux échelles locales, elles présentent, selon nous, un grand intérêt dans le cadre de la mise en place d’un sentiment communautaire dans l’Arc jurassien. En effet, le devenir de cet espace transfrontalier doit s’ancrer dans le partage des valeurs des deux pays frontaliers afin d’endiguer les risques de repli identitaire. Dans sa stratégie de coopération transfrontalière 2016-2020, la Conférence Transjurassienne (CTJ) propose de promouvoir le sentiment d’une communauté de destin (CTJ, 2015), thématique é…
