Impaired expression of heat shock proteins (HSPs) and increased oxidative stress may contribute to the pathophysiology of diabetes by disrupted tissue protection. Acute exercise induces oxidative stress, whereas exercise training up-regulates endogenous antioxidant defenses and HSP expression. Although diabetic nephropathy is a major contributor to diabetic morbidity, information regarding the effect of HSPs on kidney protection is limited. The present study evaluated the effects of 8-week exercise training on kidney HSP expression and markers of oxidative stress at rest and after acute exercise in rats with or without streptozotocin-induced diabetes...

Controlled human exposure to the oxidant air pollutant ozone causes decrements in lung function and increased inflammation as evidenced by neutrophil influx into the lung and increased levels of proinflammatory cytokines in the airways. Here we describe a targeted metabolomics evaluation of human bronchioalveolar lavage fluid (BALF) following controlled in vivo exposure to ozone to gain greater insight into its pulmonary effects. In a two-arm cross-over study, each healthy adult human volunteer was randomly exposed to filtered air (FA) and to 0...

Skeletal muscle aging is associated with loss of mass, function, and strength-a condition known as sarcopenia. It has been reported that sarcopenia can be attenuated by physical exercise. Therefore, we investigated whether 2 different physical exercise protocols could modulate and induce changes in oxidative and inflammatory parameters, as well as in BDNF and DNA repair enzyme levels in skeletal muscle tissue of aged rats. Aging Wistar rats performed treadmill or strength training for 50 min 3 to 4 times a week for 8 weeks...

Historically, heat has been used in various clinical and sports rehabilitation settings to treat soft tissue injuries. More recently, interest has emerged in using heat to pre-condition muscle against injury. The aim of this narrative review was to collate information on different types of heat therapy, explain the physiological rationale for heat therapy, and to summarise and evaluate the effects of heat therapy before, during and after muscle injury, immobilisation and strength training. Studies on skeletal muscle cells demonstrate that heat attenuates cellular damage and protein degradation (following in vitro challenges/insults to the cells)...

The objective of this work is to evaluate the potential effect of cardiac stress exercise on the accumulation of [123 I]IAZA, a radiopharmaceutical used to image focal tissue hypoxia, in otherwise normal myocardium in healthy volunteers, and to determine the impact of exercise on [123 I]IAZA pharmacokinetics. The underlying goal is to establish a rational basis and a baseline for studies of focal myocardial hypoxia in cardiac patients using [123 I]IAZA. Three healthy male volunteers ran the 'Bruce' treadmill protocol, a clinically-accepted protocol designed to expose myocardial ischemia in patients...

INTRODUCTION: An acute bout of strenuous exercise in humans results in transient impairment of NO-dependent function, but it remains unknown whether this phenomenon is associated with increased risk of post-exercise thrombotic events. This study aimed to evaluate effects of a single bout of exhaustive running in mice on the balance of vascular nitric oxide (NO)/reactive oxygen species (ROS) production, and on thrombogenicity. METHODS: At different time-points (0h, 2h and 4h) after exercise and in sedentary C57BL/6 mice the production of NO and superoxide (O2) in aorta was measured by electron paramagnetic resonance (EPR) spin trapping and by dihydroethidium (DHE)/HPLC-based method, respectively, while collagen-induced thrombus formation was analyzed in a microchip-based flow-chamber system (T-TAS)...

Circulating microparticles (MPs) are biological vectors of information within the cardiovascular system, eliciting both deleterious and beneficial effects on the vasculature. Acute exercise has been shown to alter MP concentrations, likely through a shear stress-dependent mechanism, however evidence is limited. Therefore, we investigated the effect of exercise intensity on plasma levels of CD34+ and CD62E+ MPs in young, healthy men and women. Blood samples were collected before, during, and after two energy-matched bouts of acute treadmill exercise: interval exercise (10 × 1-minute intervals at ∼95% VO2max ) and continuous exercise (65% VO2max )...

Heat shock protein 60 (HSP60) is a key protein in the crosstalk between cellular stress and inflammation. However, the status of HSP60 in diabetes and obesity is unclear. In the present study, we investigated the hypothesis that HSP60 expression levels in the adipose tissue of human obese adults with and without diabetes are different and physical exercise might affect these levels. Subcutaneous adipose tissue (SAT) and blood samples were collected from obese adults with and without diabetes ( n  = 138 and n  = 92, respectively, at baseline; n  = 43 for both groups after 3 months of physical exercise)...

To uncover potential factors that may be involved in the impaired regenerative capacity of aged skeletal muscle, we comprehensively assessed the molecular stress response following muscle damage in old and young individuals. 10 young (22.7 ± 2.25 yrs) and 8 physically active old (70.9 ± 7.5 yrs) subjects completed a bout of 300 lengthening contractions (LC), and muscle biopsies were taken pre-exercise and at 3, 24, and 72 h post-LC. Both age groups performed the same amount of work during LC, with the old group displaying a resistance to LC-induced fatigue during the exercise...

This study investigates the relationship between mindfulness, meditation, cognition and stress in people with Alzheimer's disease (AD), dementia, mild cognitive impairment and subjective cognitive decline. Accordingly, we explore how the use of meditation as a behavioural intervention can reduce stress and enhance cognition, which in turn ameliorates some dementia symptoms. A narrative review of the literature was conducted with any studies using meditation as an intervention for dementia or dementia-related memory conditions meeting inclusion criteria...

AIMS: Patients with interstitial cystitis/painful bladder syndrome (IC/PBS) commonly suffer from widespread pain and mood disorder, which has been attributed to improper functioning of the hypothalamic-pituitary-adrenal (HPA) axis. Voluntary exercise has been shown to improve HPA axis function, therefore we are determining whether voluntary wheel running can attenuate urological pain and dysfunction following neonatal maternal separation (NMS) in female mice. METHODS: Mice underwent NMS for 3 h/day from postnatal Day 1-21, were caged with free access to running wheels at 4 weeks of age, and assessed 4 weeks later for bladder sensitivity, micturition, reward behavior, mast cell degranulation, and HPA axis-related in vitro analysis...

Recently, nongenetic animal models to study the onset and development of Alzheimer's disease (AD) have appeared, such as the intrahippocampal infusion of peptides present in Alzheimer amyloid plaques [i.e., amyloid-β (Aβ)]. Nonpharmacological approaches to AD treatment also have been advanced recently, which involve combinations of behavioral interventions whose specific effects are often difficult to determine. Here we isolate the neuroprotective effects of three of these interventions-environmental enrichment (EE), anaerobic physical exercise (AnPE), and social enrichment (SE)-on Aβ-induced oxidative stress and on impairments in learning and memory induced by Aβ...

BACKGROUND: Heat stress limits endurance exercise performance. Combining precooling and warm-up prior to endurance exercise in the heat may exploit the benefits of both strategies while avoiding the potential negative consequences of each. This study tested the hypothesis that precooling combined with warm-up improves time trial cycling performance in the heat relative to either treatment alone. METHODS: Nine healthy men completed three 16.1-km time trials in 33°C after: 1) precooling (ice slurry and ice vest) alone (PREC); 2) warm-up alone (WU); or 3) PREC plus WU (COMBO)...

BACKGROUND: Chronic obstructive pulmonary disease (COPD) patients often show skeletal muscle dysfunction that has a prominent negative impact on prognosis. The study aims to further explore underlying mechanisms of skeletal muscle dysfunction as a characteristic systemic effect of COPD, potentially modifiable with preventive interventions (i.e. muscle training). The research analyzes network module associated pathways and evaluates the findings using independent measurements. METHODS: We characterized the transcriptionally active network modules of interacting proteins in the vastus lateralis of COPD patients (n = 15, FEV1 46 ± 12% pred, age 68 ± 7 years) and healthy sedentary controls (n = 12, age 65 ± 9  years), at rest and after an 8-week endurance training program...
