Both chronic mild stress and an injection of corticosterone induce depression-like states in rodents. To further link mitochondrial dysfunction to the pathophysiology of major depression, here we describe two rat models of a depressive-like state induced by chronic unpredictable mild stress (CUMS) or corticosterone treatment (CORT). It is also a ...

The assessment of exercise-induced bronchoconstriction (EIB) in athletes requires the measurement of forced expiratory volume in 1 s (FEV(1)) before and after vigorous exercise or a surrogate of exercise such as eucapnic voluntary hyperpnoea (EVH) of dry air or mannitol dry powder. Exercise testing in a laboratory has a low ...

Stroke is a major cause of death worldwide. Previous studies have suggested both exercise and mitochondrial biogenesis contribute to improved post-ischemic recovery of brain function. However, the exact mechanism underlying this effect is unclear. On the other hand, the benefit of exercise-induced mitochondrial biogenesis in brain has been confirmed. In ...

There is some evidence that singing lessons may be of benefit to patients with chronic obstructive pulmonary disease (COPD). It is not clear how much of this benefit is specific to singing and how much relates to the classes being a group activity that addresses social isolation. Patients were randomised ...

Strenuous exercise induces delayed-onset muscle damage including oxidative damage of cellular components. Oxidative stress to muscle cells impairs glucose uptake via disturbance of insulin signaling pathway. We investigated glucose uptake and insulin signaling in relation to oxidative protein modification in muscle after acute strenuous exercise. ICR mice were divided into ...

Exercise-induced angiogenesis in skeletal muscle involves both non-sprouting and sprouting angiogenesis and results from the integrated responses of multiple systems and stimuli. VEGF-A (vascular endothelial growth factor A) levels are increased in exercised muscle and have been demonstrated to be critical for exercise-induced capillary growth. Only limited information is available ...

Dopamine (DA) and noradrenaline (NA) modulate responses to nociceptive stimuli, within the dorsal horn of the spinal cord. Both neurotransmitters may play a role in supraspinal regulation in response to proprioceptive afferences to the dorsal horn. However, direct evidence of changes in neurotransmitter release within the dorsal horn due to ...

Events arising within the central nervous system seem to play a major factor in the aetiology of hyperthermia-induced fatigue. Thus, various studies with superimposed electrical nerve stimulation or transcranial magnetic stimulation have shown that both passive and exercise-induced hyperthermia will impair voluntary motor activation during sustained maximal contractions. In humans ...

INTRODUCTION: Oxidative stress is induced by both cigarette smoking and acute exercise. It has also been reported that exercise can induce plasma oxidative stress in young cigarette smokers. However, no previous report has demonstrated that exercise induces pulmonary oxidative stress in cigarette smokers. The aim of this study was to ...

Controlled mechanical ventilation (MV) is a life-saving measure for patients in respiratory failure. However, MV renders the diaphragm inactive leading to diaphragm weakness due to both atrophy and contractile dysfunction. It is now established that oxidative stress is a requirement for MV-induced diaphragmatic proteolysis, atrophy, and contractile dysfunction to occur. ...

During endurance exercise, most (≈75%) of the energy derived from the oxidation of metabolic fuels and ATP hydrolysis of muscle contraction is liberated as heat, the accumulation of which leads to an increase in body temperature. For example, the temperature of exercising muscles can rise to 40°C. Although severe heat ...

OBJECTIVE AND PATIENT: To report an atypical case of exercise-induced bilateral brachialis and brachioradialis rhabdomyolysis in a 25-year-old woman. Persistent focal muscle pain, atypical by its duration and intensity, even after moderate exercise, should prompt the search for rhabdomyolysis and discuss the possibility of acute compartment syndrome. MRI images can ...

Regular physical exercise causes resting bradycardia. This exercise-induced resting bradycardia may be associated with exercise-induced changes in Cardiac autonomic nervous activities (CANA). Power Spectral Analysis (PSA) of Heart rate variability (HRV) is one of the most promising new techniques to quantify CANA. Regular physical exercise induced bradycardia is associated with ...

Despite regular exercise benefits, acute exhaustive exercise elicits oxidative damage in liver. The present study determined the hepatoprotective properties of ginsenoside-Rg1 against exhaustive exercise-induced oxidative stress in rats. Forty rats were assigned into vehicle and ginsenoside-Rg1 groups (0.1 mg/kg bodyweight). After 10-week treatment, ten rats from each group performed exhaustive swimming. ...

We hypothesized that prior exercise would prevent postprandial lipaemia (PPL)-induced increases in intracellular reactive oxygen species (ROS) in three distinct circulating angiogenic cell (CAC) subpopulations. CD34(+), CD31(+)/CD14(-)/CD34(-), and CD31(+)/CD14(+)/CD34(-) CACs were isolated from blood samples obtained from 10 healthy men before and 4 h after ingesting a high fat meal ...

Asthma is a heterogeneous disease characterized by abnormal airway pathophysiology and susceptibility to different stimuli, as exemplified by a subset of patients with exercise-induced bronchoconstriction. Induced sputum provides a noninvasive method to sample airway biofluids that are enriched in proteins. We hypothesized that novel mechanisms in the pathogenesis of asthma ...

Whole body vibration with resistive exercise is a promising countermeasure against some weightlessness-induced dysfunctions. Objective: to study if the combination of low-magnitude whole body vibration with a resistive exercise can prevent the cardiovascular deconditioning induced by a non-strict 60-day head-down bed rest (ES-IBREP study: Earth Star International Bed Rest Experiment ...

Chronic mountain sickness (CMS) is a major public health problem in mountainous regions of the world. In its more advanced stages, exercise intolerance is often found, but the underlying mechanism is not known. Recent evidence indicates that exercise-induced pulmonary hypertension is markedly exaggerated in CMS. We speculated that this problem ...

Exercise is an effective intervention to treat fatty liver. However, the mechanism(s) that underlie exercise-induced reductions in fatty liver are unclear. Here we tested the hypothesis that exercise requires hepatic glucagon action to reduce fatty liver. C57BL/6 mice were fed high-fat diet (HFD) and assessed using magnetic resonance, biochemical, and ...

An active lifestyle is widely recognized as having a beneficial effect on cardiovascular health. However, no clear consensus exists as to whether exercise training increases overall physical activity energy expenditure (PAEE) or whether individuals participating in regular exercise compensate by reducing their off-exercise physical activity. The purpose of this study ...
