Chronic moderate exercise has been reported to reduce pro-inflammatory cytokines. To analyze the molecular mechanisms by which training exerts these effects, epigenetic influences of age and on ASC gene, is responsible for IL-1β IL-18 secretion, were investigated gene methylation. Further, relationship between carcinogenesis exercise, methylation p15 tumor suppressive was also analyzed. High-intensity interval walking consisting 3 min low-intensity at 40% peak aerobic capacity followed a...

Hypothesis Whether increasing peak aerobic capacity for walking (V̇ 2peak ) by interval training (IWT) is closely linked with decreasing the indices of lifestyle-related diseases (LSDs) in middle-aged and older people were examined. Methods For 4 months from April to September 2005 or 2006, 246 males 580 females (∼65 years) performed IWT consisting ≥5 sets fast at ≥70% V̇ 3 min followed slow ≤40% ≥4 days/week. Before after IWT, we measured , body mass index (BMI), %body fat, arterial blood...
The stimulus-response characteristics of cardiopulmonary baroreflex control forearm vascular resistance (FVR) were studied in five unfit [UF, maximal O2 consumption (VO2 max) = 38.5 ml X min-1 kg-1] and six fit (F, VO2 max 57.0 kg-1) subjects. We assessed the relationship between reflex stimulus, i.e., changes central venous pressure (CVP) response, FVR, during selective unloading mechanoreceptors with lower body negative (0 to -20 mmHg). linear FVR CVP, gain this baroreflex, was...
To examine whether the biased estimation of oxygen consumption rate (VO2, mL x kg(-1) min(-1)) by accelerometry during incline walking can be improved addition altitude changes as measured barometry.We VO2 respiratory gas analysis and vector magnitude (VM, G) from triaxial accelerations in 42 healthy people (mean +/- SD age = 63 7 yr) graded on a treadmill while was varied -15% to +15%. They walked at subjectively slow, moderate, fast speeds level uphill inclines and, these, their fastest...
We examined whether protein-carbohydrate (CHO) supplementation immediately after exercise each day during aerobic training facilitated plasma volume (PV) expansion and thermoregulatory cardiovascular adaptations in older men. Fourteen moderately active men [68 +/- 5 (SD) yr] were divided into two groups so as to have no significant differences anthropometric measures, PV, peak oxygen consumption rate (Vo(2peak)). Each group was provided with a mixture of protein CHO (3.2 kcal, 0.18 g...
Magnetic properties of TiFe x Co 1- have been measured at temperatures between 4.2 and 300 K. For the compositions 0.4≦ ≦0.8 they are interpreted in terms a weak itinerant electron ferromagnet model. The slope M 2 versus H / curves rapidly increases with decreasing iron concentration, which is good agreement result expected from electronic specific heat coefficient.

Plasma volume (PV) expansion by endurance training and/or heat acclimatization is known to increase aerobic and thermoregulatory capacities in humans. Also, higher erythrocyte (EV) fractions blood are improve these capacities. We tested the hypothesis that a hypobaric hypoxic warm environment would peak power (V˙o 2 ) forearm skin vascular conductance (FVC) response increased esophageal temperature (T es more than either alone, increasing both PV EV. Twenty men were divided into four...
Plasma proteome analysis requires sufficient power to compare numerous samples and detect changes in protein modification, because the content of human varies significantly among individuals, many plasma proteins undergo bloodstream. A label-free proteomics platform developed our laboratory, termed "Two-Dimensional Image Converted Analysis Liquid chromatography mass spectrometry (2DICAL)," is capable these tasks. Here, we describe successful detection novel prolyl hydroxylation...
We examined whether protein and carbohydrate (CHO) supplementation during 5-day training enhanced plasma volume (PV) expansion thermoregulatory cardiovascular adaptations in young men. Eighteen men [age 23 ± 4 (SD) yr] were divided into two groups according to supplements: placebo (CNT: 0.93 kcal/kg, 0.00 g protein/kg, n = 9) CHO (Pro-CHO: 3.6 0.36 9).

Physical fitness has been reported to decrease the risk of lifestyle-related diseases. The present study evaluated genome-wide methylation under hypothesis that interval walking training (IWT) imparted beneficial effects on health, particularly by epigenetically ameliorating susceptibility inflammation. We screened DNA from peripheral blood samples via microarray for genes whose was affected IWT, paying special attention promoter regions, and identified over 40 hyper- or hypo-methylated...
Patients with Alzheimer's disease (AD) often present apathy symptoms resembling the decreased motivation observed in depressed patients. Therefore, differentiating initial phase of AD from late life depression may be difficult some cases. Near-infrared spectroscopy (NIRS) is a functional neuroimaging modality that uses near-infrared light to measure changes hemoglobin concentration on cortical surface during activation tasks. The objective this study was investigate differences brain...
