The expressions of Fas, FADD, and activated caspases 8 and 3, as well as the expressions of Bax, Bak, Bax/Bcl-2, Bak/Bcl-xL, cytosolic cytochrome c, and activated caspases 9 and 3 were increased in the HF group were significantly reversed in HFLF administrated group.

Attenuation of Magnesium Sulfate on CoCl₂-Induced Cell Death by Activating ERK1/2/MAPK and Inhibiting HIF-1α via Mitochondrial Apoptotic Signaling Suppression in a Neuronal Cell Line.

Magnesium sulfate (MgSO₄) ameliorates hypoxia/ischemia-induced neuronal apoptosis in a rat model. This study aimed to investigate the mechanisms governing the anti-apoptotic effect of MgSO₄ on cobalt chloride (CoCl₂)-exposed NB41A3 mouse neuroblastoma cells. MgSO₄ increased the viability of NB41A3 cells treated with CoCl₂ in a dose-dependent manner.

Cardiac Fas-Dependent and Mitochondria-Dependent Apoptotic Pathways in a Transgenic Mouse Model of Huntington's Disease.

Huntington's disease is an autosomal dominant neurodegenerative disease caused by a CAG repeat expansion in the huntingtin gene. Heart disease is the second leading cause of death in patients with Huntington's disease. This study was to evaluate whether cardiac Fas-dependent and mitochondria-dependent apoptotic pathways are activated in transgenic mice with Huntington's disease.

Anti-apoptotic effect of San Huang Shel Shin Tang cyclodextrin complex (SHSSTc) on CCl4 -induced hepatotoxicity in rats.

The metabolic loading is heavier in liver especially when injured or inflammation. San Huang Shel Shin Tang (SHSST) was an old traditional herbal decoction, which composed with Rheum officinale Baill, Scutellaria baicalnsis Geprgi and Coptis chinensis Franch (1:1:2 in weight), can provide a liver protection effects. We used a beta-cyclodextrin (β-CD) drug modification method in reduce of the necessary dose of the SHSST.

Comparative effects of snoring sound between two minimally invasive surgeries in the treatment of snoring: a randomized controlled trial.

Shear cushions reduce the impact loading rate during walking and running.

In addition to vertical ground reaction force (GRF), anterior-posterior GRF with a greater external moment arm may be another repetitive impact force that contributes to overuse running injuries. In this study, a shear cushion device was placed between the sole of a shoe and the ground to reduce not only the vertical loading, but also the anterior-posterior loading while walking and running. For this study, 15 healthy male runners classified as heel strikers (height: 173.

Altitude training improves glycemic control.

Unlabelled: Under altitude hypoxia condition, energy reliance on anaerobic glycolysis increases to compensate the shortfall caused by reduced fatty acid oxidation. Short-term moderate altitude exposure plus endurance physical activity has been found to improve glucose tolerance (not fasting glucose) in humans, which is associated with the improvement in the whole-body insulin sensitivity. However, most of people cannot accommodate high altitude exposure above 4500 M due to acute mountain sickness and insulin resistance.

Performance enhancement among adolescent players after 10 weeks of pitching training with appropriate baseball weights.

Compared with regulation-weight baseballs, lightweight baseballs generate lower torque on the shoulder and elbow joints without altering the pitching movement and timing. This study investigates the throwing accuracy, throwing velocity, arm swing velocity, and maximum shoulder external rotation (MSER) of adolescent players after 10 weeks of pitching training with appropriate lightweight baseballs. We assigned 24 adolescent players to a lightweight baseball group (group L) and a regulation-weight baseball group (group R) based on their pretraining throwing velocity.

Efficacy of therapeutic play for pediatric brain tumor patients during external beam radiotherapy.

Objective: External beam radiotherapy (EBRT) is frequently used to improve disease control for pediatric brain tumor patients. However, to facilitate the radiotherapy (RT) procedure, "forced" type interventions including conscious sedation or general anesthesia are frequently used to manage patients' fear and anxiety. The aim of this study was to investigate the effects of therapeutic play (TP) in reducing anxiety for pediatric brain tumor patients treated by EBRT.

Chronic effects of whole-body vibration on jumping performance and body balance using different frequencies and amplitudes with identical acceleration load.

Unlabelled: Previous studies on vibration training have all been based on protocols at different combinations of frequencies and amplitudes without controlling the loading intensity.

Objectives: This study investigated the effect of an 8-week vibration training program, under identical acceleration loads with various frequencies and amplitudes, on jumping performance, muscle activation and body balance.

Design: Fifty young adults were randomly assigned to an high-frequency (32 Hz, 1mm, and 4 g), low-frequency (18 Hz, 3 mm, and 4 g), or a control group.

Effect of acute DHEA administration on free testosterone in middle-aged and young men following high-intensity interval training.

With advancing age, plasma testosterone levels decline, with free testosterone levels declining more significantly than total testosterone. This fall is thought to underlie the development of physical and mental weakness that occurs with advancing age. In addition, vigorous exercise can also lower total and free testosterone levels with the decline greatest in physically untrained men.

Deep ocean mineral water accelerates recovery from physical fatigue.

Background: Deep oceans have been suggested as a possible site where the origin of life occurred. Along with this theoretical lineage, experiments using components from deep ocean water to recreate life is underway. Here, we propose that if terrestrial organisms indeed evolved from deep oceans, supply of deep ocean mineral water (DOM) to humans, as a land creature, may replenish loss of molecular complexity associated with evolutionary sea-to-land migration.

The effects of passive leg press training on jumping performance, speed, and muscle power.

Passive leg press (PLP) training was developed based on the concepts of the stretch-shortening cycle (SSC) and the benefits of high muscle contraction velocity. Passive leg press training enables lower limb muscle groups to apply a maximum downward force against a platform moved up and down at high frequency by an electric motor. Thus, these muscle groups accomplished both concentric and eccentric isokinetic contractions in a passive, rapid, and repetitive manner.

Oral Rg1 supplementation strengthens antioxidant defense system against exercise-induced oxidative stress in rat skeletal muscles.

Background: Previous studies reported divergent results on nutraceutical actions and free radical scavenging capability of ginseng extracts. Variations in ginsenoside profile of ginseng due to different soil and cultivating season may contribute to the inconsistency. To circumvent this drawback, we assessed the effect of major ginsenoside-Rg1 (Rg1) on skeletal muscle antioxidant defense system against exhaustive exercise-induced oxidative stress.

Cross-generation link between inactive behavior of schoolchildren and metabolic disease category of parents.

In this study, we determined the cross-generation link between sedentary behavior of schoolchildren with their 6-year BMI progression pattern and metabolic disease category of their parents. Anthropometric data of 11,190 elementary schoolchildren (aged 13) were retrospectively tracked from 2003 to 2009, and classified into two groups: Normal (N = 9793) and Metabolic Disorders (N = 1397), based on the disease category of their parents (under at least one medication for stroke, coronary heart disease (CAD), diabetes, and hypertension). Schoolchildren's weekly time spending on reading, computer use, video game, music listening, radio listening, TV watching, and movie watching, was reported with parental assistance via questionnaires.

Cell type specificity of female lung cancer associated with sulfur dioxide from air pollutants in Taiwan: an ecological study.

Background: Many studies have examined the association between air pollutants (including sulfur dioxide [SO2], carbon monoxide [CO], nitrogen dioxide [NO2], nitric oxide [NO], ozone [O3], and particulate matter < 10 μm [PM10]) and lung cancer. However, data from previous studies on pathological cell types were limited, especially for SO2 exposure. We aimed to explore the association between SO2 exposure from outdoor air pollutants and female lung cancer incidence by cell type specificity.

Ginsenoside-Rg1 Protects the Liver against Exhaustive Exercise-Induced Oxidative Stress in Rats.

Background And Purpose: Bufalin and cinobufagin exhibit cardiotonic and natriuretic activities. The aim of this study was to evaluate the effects of bufalin and cinobufagin on aldosterone and cortisol secretion and their mechanisms of action in human adrenocortical cells (NCI-H295).

Experimental Approach: H295 cells were incubated with bufalin or cinobufagin in the presence or absence of angiotensin II (Ang II), forskolin, 8-Br-cAMP, corticosterone or deoxycortisol.

Effects of one-year swimming training on blood pressure and insulin sensitivity in mild hypertensive young patients.

Unlabelled: Swimming is a lifestyle intervention recommended by many clinicians in the prevention and treatment of hypertension. Yet, not all studies have agreed that swimming training can reduce blood pressure (BP). Inclusion of normotensive subjects could be a confounder for discrepancies among studies.

Involvement of ERK phosphorylation in the prevention of ischemia-induced ovarian follicular depletion by stem cells.

Ovarian failure is commonly caused by aging, autoimmune disease, menopause and cancer therapy. We used an ischemic model in the ovary to test the hypothesis that stem cells are helpful for ovarian regeneration after injury. Three treatment regimes were employed: sham-operated control, ligation plus PBS, and ligation plus immortalized human bone marrow stromal cells (stem cells) groups.

Enhancement of vasorelaxation in hypertension following high-intensity exercise.

Exercise can ameliorate vascular dysfunction in hypertension, but its underlying mechanism has not been explored thoroughly. We aimed to investigate whether the high-intensity exercise could enhance vasorelaxation mediated by insulin and insulin-like growth factor-1 (IGF-1) in hypertension. Sixteen-week-old spontaneously hypertensive rats were randomly divided into non-exercise sedentary (SHR) and high-intensity exercise (SHR+Ex) groups conducted by treadmill running at a speed of 30 m/ min until exhaustion.

Predictive validity of a three-dimensional model of performance anxiety in the context of tae-kwon-do.

We tested the predictive validity of the recently validated three-dimensional model of performance anxiety (Chang, Hardy, & Markland, 2009) with elite tae-kwon-do competitors (N = 99). This conceptual framework emphasized the adaptive potential of anxiety by including a regulatory dimension (reflected by perceived control) along with the intensity-oriented dimensions of cognitive and physiological anxiety. Anxiety was assessed 30 min before a competitive contest using the Three-Factor Anxiety Inventory.

Parasympathetic nervous activity mirrors recovery status in weightlifting performance after training.

Heart rate variability (HRV) and parasympathetic power are closely related to the well-being and health status in humans. The main goal of the study was to determine whether these measures can reflect recovery status after weight training. After a 10-day detraining period, 7 weightlifters were challenged with a 2-hour weight training which elicited approximately fourfold increases in circulating muscle creatine kinase level and protracted pain feeling (p < 0.
