Accumulated research supports the idea that exercise could be an option of potential prevention and treatment for drug addiction. During the past few years, there has been increased interest in investigating of sex differences in exercise and drug addiction. This demonstrates that sex-specific exercise intervention strategies may be important for preventing and treating drug addiction in men and women. However, little is known about how and why sex differences are found when doing exercise-induced interventions for drug addiction. In this review, we included both animal and human that pulled subjects from a varied age demographic, as well as neurobiological mechanisms that may highlight the sex-related differences in these potential to assess the impact of sex-specific roles in drug addiction and exercise therapies. © 2015 Elsevier Inc.

Exercise has benefit for perimenopause women in many ways, such as affective disorders. Our previous study has demonstrated that inflammation in hippocampus contributes to development of depression-like behavior in ovariectomized (OVX) rats. Recently, oligomerization domain-like receptor family pyrin domain-containing 3 (NLRP3) inflammasome has been implicated to be involved in lipopolysaccharide (LPS)- and chronic stress-induced depression-like behavior in rodents. We sought to investigate whether ovariectomy-induced depression-like behavior is associated with NLRP3 inflammasome activation in brain and the effect of exercise on NLRP3 inflammasome activation in this model. The results showed that ovariectomy resulted in depression-like behavior in mice and an increase in levels of IL-1β and IL-18 in hippocampus. Exercise ameliorated the depression-like behavior and decreased levels of IL-1β and IL-18 in hippocampus. The level of IL-1β and IL-18 in hippocampus correlated to depression-like behavior in OVX mice. The levels of NLRP3, cleaved caspase-1 P10 and CD11b in hippocampus were increased in OVX mice compared with control group. Exercise could reduce the levels of NLRP3, cleaved caspase-1 P10 and CD11b in OVX mice. Our study suggests that NLRP3 inflammasome activation contribute to inflammation in hippocampus upon to deprivation of ovary. Exercise amelioration of depression-like behavior is associated with suppression of NLRP3 inflammasome activation in hippocampus of this model. © 2016 Elsevier B.V..

Peripheral neuropathy is a widespread and potentially incapacitating pathological condition that encompasses more than 100 different forms and manifestations of nerve damage. The diverse pathogenesis of peripheral neuropathy affects autonomic, motor and/or sensory neurons, and the symptoms that typify the condition are abnormal cutaneous sensation, muscle dysfunction and, most notably, chronic pain. Chronic neuropathic pain is difficult to treat and is often characterized by either exaggerated responses to painful stimuli (hyperalgesia) or pain resulting from stimuli that would not normally provoke pain (allodynia). The objective of this review is to provide an overview of some pathways associated with the development of peripheral neuropathy and then discuss the benefits of exercise interventions. The development of neuropathic pain is a highly complex and multifactorial process, but recent evidence indicates that the activation of spinal glial cells via the enzyme glycogen synthase kinase 3 and increases in the production of both pro-inflammatory cytokines and brain derived neurotropic factor are crucial steps. Since many of the most common causes of peripheral neuropathy cannot be fully treated, it is critical to understand that routine exercise may not only help prevent some of those causes, but that it has also proven to be an effective means of alleviating some of the condition's most distressing symptoms. More research is required to elucidate the typical mechanisms of injury associated with peripheral neuropathy and the exercise-induced benefits to those mechanisms. © 2014 Dobson, McMillan and Li.

3-Hydroxy-3-methylglutaryl coenzyme A reductase inhibitors (statins) exert pleiotropic effects on the cardiovascular system, in part through a decrease in reactive oxygen species (ROS) formation and reduction of vascular inflammation. To elucidate the molecular mechanisms involved in these effects, we investigated the effect of statins on TNF-α-induced ROS production, vascular cell adhesion molecule-1 (VCAM-1) and intercellular adhesion molecule-1 (ICAM-1) expression in human aortic endothelial cells (HAECs). Exposure of HAECs to TNF-α caused production of ROS via Rac-1 membrane translocation and activation. The Rac-1 activation and ROS liberation mediated TNF-stimulated NF-κB activation and the subsequent VCAM-1 and ICAM-1 expression. Extracellular-signal-regulated kinase 5 (ERK5) plays a central role in inhibiting endothelial inflammation. Immune complex kinase assay of protein extracts from HAECs treated with atorvastatin revealed increased ERK5 activity in a time- and dose-dependent manner. In addition, pretreatment with atorvastatin inhibited TNF-α-induced ROS production and VCAM-1 and ICAM-1 expression. Chemical or genetic inhibition of ERK5 ablated the statins inhibition of Rac-1 activation, ROS formation, NF-κB, VCAM-1 and ICAM-1 expression induced by TNF-α. Taken together, statins, via ERK5 activation, suppress TNF-stimulated Rac-1 activation, ROS generation, NF-κB activation and VCAM-1 and ICAM-1 expression in human ECs, which provides a novel explanation for the pleiotropic effects of statins that benefit the cardiovascular system. © 2013 Elsevier Inc.

This study aimed to determine the effect of acute exercise in the potential context of non-pharmacological intervention for methamphetamine (MA)-related craving; we additionally determine its effect on the inhibitory control induced by standard and MA-related tasks according to behavioral and neuroelectric measurements among MA-dependent individuals. The present study employed a within-subjects, counterbalanced design. A total of 24 participants who met the DSM-IV criteria for MA dependence were recruited. The craving level, reaction time, and response accuracy, as well as the event-related potential (ERP) components N2 and P3, were measured following exercise and the control treatment in a counterbalanced order. The exercise session consisted of an acute stationary cycle exercise at a moderate intensity, whereas the control treatment consisted of an active reading session. The self-reported MA craving was significantly attenuated during, immediately following, and 50. min after the exercise session compared with the pre-exercise ratings, whereas the craving scores at these time points following exercise were lower than those for the reading control session. Acute exercise also facilitated inhibitory performance in both the standard and MA-related Go/Nogo tasks. A larger N2 amplitude, but not a larger P3 amplitude, was observed during both tasks in the exercise session and the Nogo condition compared with the reading control session and the Go condition. This is the first empirical study to demonstrate these beneficial effects of acute aerobic exercise at a moderate intensity on MA-related craving and inhibitory control in MA-dependent individuals. These results suggest a potential role for acute aerobic exercise in treating this specific type of substance abuse. © 2015.

Ageing Research Reviews | Year: 2017
Background Aging is an important contributor to olfactory system deterioration in humans, leading to increased health and safety risks as well as affecting the quality of life. However, it is currently unknown when age-related olfactory deterioration begins in humans and thus when to initiate interventions to prevent or slow it. Objective To determine the decade in which olfactory function begins to deteriorate in healthy humans by determining when odor identification is first impaired. Data source and study selection Studies cited in the PubMed database were searched from its inception to March 2017 using the terms “olfac*” or “smell” and “ag*”. The effect size of each comparison was calculated. Results In this meta-analysis, the effect sizes as determined using Cohen's d for the comparisons between 30 and 39.9- and 40–49.9-year-olds was 0.06 (95% CI: −0.17 to 0.29), between 40–49.9-year-olds was 0.62 (95% CI: 0.20–1.04), considered a medium effect size, and between 35-55-year-olds and those >55 years old was 1.12 (95% CI: 1.06–1.45), considered a very large effect. Conclusion Olfactory function deterioration, as determined by an impaired ability to identify odors, starts in the fifth decade of life in healthy humans. © 2017 Elsevier B.V.

Major depressive disorder (MDD) and type II diabetes mellitus (T2DM) are highly co-morbid, and there may be a bi-directional connection between the two. Herein, we have described a mouse model of a depression-like and insulin-resistant (DIR) state induced by the co-treatment of high-fat diet (HFD) and corticosterone (CORT). 5-Aminoimidazole-4-carboxamide-1-β-d- ribofuranoside (AICAR), a pharmacological activator of AMP-activated protein kinase (AMPK), was originally used to improve insulin resistance (IR). Interestingly, our results show a clear potential for AICAR as a putative antidepressant with a chronic action on the DIR mice. In contrast to the traditional antidepressants, AICAR as a promising antidepressant avoids reducing insulin actions of skeletal muscle in the context of long-term HFD. Exercise also produced antidepressant effects. Our data suggest that the effects of AICAR and exercise on DIR may further increase our understanding on the link between depression and diabetes. © 2013 Elsevier B.V.

Acupuncture in Medicine | Year: 2014
Objectives: To evaluate the effect of wet needling (related to acupuncture) and home stretching exercises on myofascial trigger points (MTrPs) in abdominal muscles for the treatment of dysmenorrhoea. Methods: The effect of wet needing of MTrPs in abdominal muscles, supplemented by home stretching exercises, was observed in 65 patients with moderate and severe primary dysmenorrhoea. The MTrPs in the abdominal region were localised and repeatedly needled with lidocaine injection. Menstrual pain was evaluated with a Visual Analogue Scale (VAS) score after every treatment, with the final evaluation made at a 1-year follow-up. Treatment was stopped when the VAS pain score reduced to =3. Symptoms scores were analysed with one-way analysis of variance. Results: The mean VAS pain score before treatment was 7.49±1.16. After a single wet needling session, 41 patients had a reduction in their VAS pain score to <3 during their following menstrual cycle, with a mean of 1.63±0.49. Twenty-four patients who needed two treatments showed a reduction in menstrual pain scores to 0.58±0.50. After 1 year, the mean VAS pain score among all patients was 0.28±0.45, with a response rate of 100%. Conclusions: Primary dysmenorrhoea was significantly reduced 1 year after wet needling to MTrPs in the abdominal region and home stretching exercises, justifying further research with controlled trials.

MicroRNAs (miRNAs) have emerged as critical regulators of numerous biological processes by modulating gene expression at the post-transcriptional level. The discovery of miRNAs as new and important regulators of gene expression is expected to broaden our biological understanding of the regulatory mechanism in muscle by adding another dimension of regulation to the diversity and complexity of gene-regulatory networks. Exercise-induced skeletal muscle injury and repair have always been among the highlights of research in sports medicine. However, many mechanism problems that occur during regeneration and repair in the aftermath of skeletal muscle injury remain unsolved. It has become increasingly clear that the regeneration of skeletal muscle development involve regulation by miRNAs. In the last few years the field has seen a rapid expansion of our knowledge of miRNAs in the regeneration of skeletal muscle. This study reviews the miRNAs related with regeneration of skeletal muscle, and discuss the regulation of their expression in muscles, and emerging themes of miRNA regulation.

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 model that allows the simultaneous study of effects of exercise preconditioning on behavioral, electrophysiological, biochemical and molecular markers in the same animal. Exercise preconditioning ahead of CUMS and CORT treatment prevents many behavioral abnormalities resulted from CUMS. The changes in mitochondrial activity in brain and reduced expressions of superoxide dismutase (SOD1, SOD2), mitofusin (Mfn1, Mfn2) as well as brain-derived neurotrophic factor (BDNF) suggest that both CORT and CUMS may impair mitochondrial function and/or expressions of mitofusion and antioxidant enzymes that, in turn, may increase oxidative stress and reduce energy production in brain with depression-like behaviors. These findings suggest an underlying mechanism by which CORT, as well as CUMS, induces brain mitochondrial dysfunction that is associated with depressive-like states. Remarkably, physical exercise is identified as a helpful and preventive measure to promote mitochondrial function and expressions of mitofusin, BDNF and antioxidant enzymes in brain, so as to protect brain energy metabolism against CUMS, rather than the compound of corticosterone. © 2011 Elsevier Ltd.
