Apelin, an endogenous ligand of the G-protein-coupled receptor APJ, is a novel myokine and may play a key role in regulating energy metabolism. The purpose of the present study was to investigate the effects of hypoxic exposure, exercise, and hypoxic exercise training on the expression of apelin and APJ in skeletal muscle of obese mice. Sixty two-months old C57BL/6J mice were randomly divided into two groups: Ten in normal diet group (N) and 50 in the high fat diet (HFD) groups. After two months of feeding, the HFD mice, whose body weight was 20% higher than the average weight of the N group, were selected as obese mice and further allocated into four groups: Control (C), Exercise (E), Hypoxia (H), and Exercise plus Hypoxia (E+H), at 8-9 mice/group. Besides body weight, measured variables in skeletal muscle were protein/mRNA levels of apelin/APJ, AMPKα-Thr172 phosphorylation, hypoxia inducible factor-1α (HIF-1α), mRNA levels of peroxisome proliferator-activated receptor α (PPARα), estrogen-related receptor (ERRα), and nuclear respiratory factor 1 (NRF1). Obese mice had significantly lower mRNA and protein expressions of apelin/ APJ in skeletal muscles than the normal body weight mice. After four weeks of interventions, hypoxic exercise training decreased body weight and increased mRNA and protein expressions of apelin and APJ, mRNA expression of ERRα, and protein expression of HIF-1α. These results indicate that changes of body weight may be associated with the levels of apelin/APJ expressions in skeletal muscle.

Background: Intermittent normobaric hypoxia training, an alternative to altitude training for athletes, may be beneficial to treat overweight and obesity. The purpose of this study is to investigate whether normobaric hypoxia training combined with low-caloric diet has the additive effect on weight loss compared with normoxia training in obese young adults. Methods: Twenty-two subjects (age 17-25 years, body mass index >27.5 kg/m2) were recruited for a 4-week residential camp of weight loss with low caloric intake, and trained at 60-70 % maximal heart rate of aerobics and 40-50 % of maximal strength of training. They were randomly assigned to either a normobaric hypoxia (HT, FiO2 = 16.4-14.5 %) or normoxia training group (NT, FiO2 = 21 %), and subjects in HT and NT groups experienced weekly 16-h normoxia and 6-h hypoxia or 22-h normoxia training, respectively. Body composition, resting blood pressure (BP) and brachial-ankle pulse wave velocity (baPWV) were determined before and after the intervention. Results: Weight loss was found in HT (-6.9 kg or -7.0 %, p < 0.01) and NT groups (-4.3 kg or -4.2 %, p < 0.01) significantly, and the former lost more weight than the latter (p < 0.01). Hypoxia training improved systolic BP (-7.6 %) and mean BP (-7.1 %) significantly (p < 0.05) despite having no effect on baPWV. Conclusion: Four weeks of normobaric hypoxia residential training with low caloric diet has an additive improvement on weight loss. It seems that normobaric hypoxia training might be a promising method to treat obesity. © 2013 Springer-Verlag Berlin Heidelberg.

Nowadays, Tai chi chuan (TCC) is practiced by millions worldwide with a range of skill levels. However, the effect of skill level on physiological response to TCC performance has yet to be clarified. In this study, physiological parameters during practicing simplified 24-form TCC were investigated and compared in 10 young high-level (HL) male TCC athletes and 10 ordinary-level (OL) male TCC practitioners with similar age and body size. Significantly higher energy expenditure, heart rate, oxygen uptake and tidal volume were found in HL group than OL group during TCC performance. The respiratory frequency and exhalation time were similar between the two groups during practicing TC; however, significantly less inhalation time was found in HL group (1.02±0.2 s) than OL group (1.12±0.28 s). Our results suggested that skill level may have considerable impact on metabolic and cardiorespiratory responses to TCC performance. TCC practitioners with different skill levels may practice TCC in different ways, which was supposed to lead to distinguishable response between the two groups. © 2013 Copyright European College of Sport Science.

Humanin (HN) has been proved to be an extensive neuroprotective peptide against AD-related and unrelated insults, but little is know about the effect of HN in inflammation response. Current studies indicated the receptors of HN have a close relationship with immune system, which led us to hypothesize HN might have a role in inflammatory response. In this study, we used lipopolysaccharide (LPS) to induce astrocyte inflammation response. This model in vitro allowed us to study the effect of HN on the pure response of astrocyte without the exogenous influence between cells in vivo. Our results showed that 1.0 μg/ml LPS induced a significant activation of astrocyte, shown as the marked increase in the glial fibrillary acidic protein (GFAP) expression, the cell viability and the number of 5-bromo-2′-deoxyuridine (BrdU)-positive living cells. Pretreatment with HN (5, 10, 20 μM) led to a significant inhibition in astrocyte overactivation in a concentration dependent manner. We also found pretreatment with HN decreased the level of proinflammatory cytokines, interleukin (IL)-6, IL-1β and tumor necrosis factor α (TNFα) induced by LPS. Furthermore, we noticed HN couldn't completely reverse the above inflammatory injury. Our findings imply that HN partly antagonizes inflammation injury induced by LPS and the protective effect of HN on astrocyte is concentration-dependent. © 2012 Springer Science+Business Media New York.

Objectives To investigate the effectiveness of a 6-month Liuzijue qigong (LQG) program in promoting physical and psychosocial function in individuals with chronic obstructive pulmonary disease (COPD). Design Single-blind, randomized controlled trial. Setting Seven hospital respiratory care centers in Beijing. Participants Individuals with COPD (N = 126; mean age 71.1 ± 2.7, range 65-85). Methods Participants were randomly assigned to one of two groups: LQG (n = 63) and control (n = 63). Subjects in the LQG group received a LQG program consisting of four 45-minute sessions each week and daily walking for 30 minutes for 6 months. Control subjects walked daily for 30 minutes. Data collection was performed at baseline, at 6 weeks, and at 6 months. Primary outcomes involved functional capacity, and secondary outcomes involved quality of life. Results The LQG group had greater improvements in the 6-minute walk test (P =.02); specific airway conductance (P =.02); monitored functional task evaluation (P =.04); Medical Outcomes Study 36-item Short-Form Health Survey (SF-36; general health (P <.001), mental health (P =.03)); Chronic Respiratory Questionnaire (dyspnea (P =.05), emotion (P =.05), and mastery (P =.04) at 6-month follow-up. After 6 months, the control group had significant improvement only on the SF-36 mental health (P =.02). Conclusion LQG promoted functional capacity and quality of life in older adults with COPD at 6 months and is a good alternative home exercise program for older adults in the rehabilitation of COPD. © 2015 The American Geriatrics Society.

In this paper, we investigate a generalized inhomogeneous fifth-order nonlinear Schrödinger equation, generated by deforming the inhomogeneous Heisenberg ferromagnetic spin system through the space curve formalism. Based on the Ablowitz-Kaup-Newell-Segur system, infinitely many conservation laws will be obtained. Via the introduction of the auxiliary functions, bilinear form and N-soliton solutions have been derived with symbolic computation. Propagation and interaction of solitons have been studied through the analytical results. Effects of the inhomogeneous functions f = μ 1 x + ν 1 and h = μ 2 x + ν 2 on the soliton velocity and interactions have been discussed graphically and analytically. © 2014 EDP Sciences, SIF, Springer-Verlag Berlin Heidelberg.

Previous studies have shown that exercise training influences potassium channel protein expression in arteries. The purpose of this study was to investigate the effect of exercise training on alterations in voltage-gated potassium channels (Kv) and large-conductance, calcium-activated potassium channels (BKCa) in thoracic aorta smooth muscle cells from spontaneously hypertensive rats (SHRs). Male SHRs were randomly assigned to a sedentary group (SHR-SED) and exercise training group (SHR-EX). Age-matched Wistar-Kyoto rats (WKYs) were used as controls. After 8 weeks of aerobic exercise training, blood pressure was significantly lower in the SHR-EX group than in the SHR-SED group. Exercise training increased the contribution of the Kv1.2 and Kv1.5 channels and decreased the contribution of BKCa channel to resting tone in the SHR-EX group compared to the SHR-SED group as indicated by vessel contractility experiments. Immunohistochemistry and Western blotting showed that Kv1.2 and Kv1.5 channel expression was significantly lower in the SHR-SED group than in the WKY group and exercise training attenuated this reduction. BKCa α-subunit expression was statistically unchanged between the groups; however, β1-subunit expression was reduced significantly by exercise training in the SHR-EX group compared to the SHR-SED group. These data suggest that exercise training reverses the pathological expression of the Kv1.2, Kv1.5, and BKCa channels in aortic myocytes from SHRs. This is one of the favorable effects of exercise training on large conduit arteries. © 2015 S. Karger AG, Basel.

OBJECTIVE—: Regular exercise is an effective nonpharmacological means of preventing and controlling hypertension. However, the molecular mechanisms underlying its effects remain undetermined. The hypothesis that hypertension increases the functional coupling of large-conductance Ca-activated K (BKCa) channels with ryanodine receptors in spontaneously hypertensive rats (SHR) as a compensatory response to an increase in intracellular Ca concentration in cerebral artery smooth muscle cells was assessed here. It was further hypothesized that exercise training would prevent this increase in functional coupling. APPROACH AND RESULTS—: SHR and Wistar–Kyoto (WKY) rats were randomly assigned to sedentary groups (SHR-SED and WKY-SED) and exercise training groups (SHR-EX and WKY-EX). Cerebral artery smooth muscle cells displayed spontaneous transient outward currents at membrane potentials more positive than −40 mV. The amplitude of spontaneous transient outward currents together with the spontaneous Ca sparks in isolated cerebral artery smooth muscle cells was significantly higher in SHR-SED than in WKY-SED. Moreover, hypertension displayed increased whole-cell BKCa, voltage-gated Ca channel, but decreased KV currents in cerebral artery smooth muscle cells. In SHRs, the activity of the single BKCa channel increased markedly, and the protein expression of BKCa (β1, but not α-subunit) also increased, but KV1.2 decreased significantly. Exercise training ameliorated all of these functional and molecular alterations in hypertensive rats. CONCLUSIONS—: These data indicate that hypertension leads to enhanced functional coupling of ryanodine receptors–BKCa to buffer pressure–induced constriction of cerebral arteries, which attributes not only to an upregulation of BKCa β1-subunit function but also to an increase of Ca release from ryanodine receptors. However, regular aerobic exercise efficiently prevents augmented coupling and so alleviates the pathological compensation and restores cerebral arterial function. © 2016 American Heart Association, Inc.

Objective: To investigate the feasibility of a non-invasive and instant method to evaluate the degree of exercise-induced muscle damage. Methods: Thirteen male college athletes (23.4 ± 1.0. year, 180.03 ± 3.51. cm, 75.93 ± 6.70. kg) took part in the trial. Measures included serum creatine kinase (CK) after eccentric and endurance exercise, and surface electromyography (sEMG) during knee extension and flexion on a Biodex unit. Relation analysis was employed between sEMG and serum CK after the eccentric and endurance exercise. Results: There were positive correlations between serum CK at 24 and 48. h after eccentric exercise and the AREA of sEMG for the slow isokinetic contraction before eccentric exercise (r=0.69, P<0.01 and 0.64, P<0.05, respectively). The zero crossing rate (ZCR) immediately after exercise was negatively correlated with serum CK at 48. h after exercise for the slow and fast tests (r=-0.63 and -0.59, P<0.05, respectively). Mean power frequency (MPF) and ZCR of sEMG at 6. h post endurance exercise were positively correlated with serum CK at 24. h (r=0.73 and 0.69, P<0.05, respectively) for the fast isokinetic test. Conclusions: Exercise-induced muscle damage as evaluated by serum CK was associated with the AREA of sEMG after eccentric exercise. The ZCR of sEMG was a good predictor of muscle damage after endurance exercise. © 2010 Elsevier Ltd.
