To compare the effects of weekly or bi-weekly dietary sessions with the same number of total lecture hours, periods, and lecture contents on weight loss, dropouts during the intervention, and the weight loss maintenance after 1 year. The study included 52 middle-aged women with at least 1 risk factor for cardiovascular disease (i.e., obesity, hypertension, dyslipidemia, and hyperglycemia) who were encouraged to lose weight. Thirty-seven women were assigned to the weekly class (self-selected weekly class group: n=26) or the bi-weekly class (self-selected bi-weekly class group: n=11) based on their preference. Fifteen women were assigned to the bi-weekly class against their will (bi-weekly class group). All groups participated in the same number of sessions (total, 26 h), and were instructed to reduce their dietary intakes to 1200 kcal/day for 13 weeks. The self-selected weekly class group attended a 2-h instructional session every week, whereas both the bi-weekly class groups received 1-h sessions twice a week. Data on the body weight of the participants was collected 1 year after the intervention using a self-administered questionnaire via mail. The self-selected bi-weekly class group had significantly fewer dropouts (self-selected weekly class group: 5 persons, 19.2%; self-selected bi-weekly class group: 1 person, 9.0%; bi-weekly class group: 8 persons, 53.3%; P<0.05). There was a significant decrease in weight (P<0.05) in all 3 groups during the intervention (self-selected weekly class group: -4.3±2.7 kg, self-selected bi-weekly class group: -6.7±3.0 kg, bi-weekly class group: -6.0±3.4 kg). However, weight loss in the self-selected bi-weekly class group was significantly greater than that in the other 2 groups. A significant change in body weight at the 1-year follow-up was not observed in any group (self-selected weekly class group: +0.4±1.3 kg, self-selected bi-weekly class group: -0.1±2.3 kg, bi-weekly class group: +0.5±0.6 kg). Repeated-measures ANOVA (time×group) revealed no significant interactions in weight loss. These results suggest that a greater frequency of dietary sessions contributes to weight loss, while a lesser frequency of dietary sessions contributed to a decrease in questionnaire recovery rates. The dropout rate in the self-selected weekly and bi-weekly class groups was lesser than that in the bi-weekly class group. Therefore, dietary sessions tailored to the needs of the participants might decrease the dropout rate.

Environmental changes in arid central Asia are prominently manifest through changes in the water balance. Lake Balkhash, the largest lake in Kazakhstan, is a shallow lake situated in a closed basin. We obtained a 600-cm-long core from the western part of the lake in 2007 and carried out analyses of fossil diatoms and ostracods, geochemistry, and grain size of the sediments. The age control of the core is based on radiocarbon ages of fossil ostracods and, in the uppermost part, the AD 1963 137Cs activity peak and the first appearance of 137Cs in AD 1952. We recognized two main diatom assemblages by detrended correspondence analysis, one characterized by the dominance of freshwater planktonic species, and the other dominated by brackish planktonic, brackish, and marine benthic, and freshwater benthic species. The first assemblage suggests higher lake levels, and the second suggests lower lake levels. The observed assemblage changes are consistent with lake-level observations recorded during the last 120 years. The diatom assemblage data from the core indicate that there were seven periods when the lake level was low during the last 2000 years; moreover, the pH of the lake changed together with the lake level. In addition, during periods when the lake level was low from AD 1260-2000, the abundance of fossil ostracods and the Ca and TOC contents were low in comparison with the periods before AD 1260. The causes of low water levels were essentially the same between Lake Balkhash and the Aral Sea during the studied period. One likely cause of the low water levels, especially those during the last 1200 years, is changes in solar activity. Furthermore, some environmental changes during the past 40 years can be explained by human activities. © 2015 Elsevier Ltd and INQUA.

Aim: To examine the effects of vigorous physical activity (PA) on intra-abdominal fat (IF) levels in obese men. Methods: Thirty-seven obese men (mean age: 47.6 ± 8.6 years) engaged in a 12-week aerobic exercise program on a regular basis (3 days/week). We divided them into low volume of vigorous PA group (n = 19) or high volume of vigorous PA group (n = 18), based on the median time spent (34.3 min/week) in vigorous PA (over 6.1 metabolic equivalents assessed by a single-axis accelerometer) throughout the program. Results: Regular exercise reduced IF levels (measured by computed tomography) from 188.1 ± 53.9 cm2 to 170.3 ± 46.6 cm2 for the low volume of vigorous PA group and from 167.9 ± 44.3 cm2 to 137.9 ± 40.6 cm2 for the high volume of vigorous PA group. Two-way (time × group) ANOVA revealed no significant interactions for the IF level. However, correlation analysis for all participants showed that time spent in vigorous PA throughout the program significantly correlated to IF reductions after adjusting for initial levels of IF, vigorous PA and weight changes (r = -0.42, P = 0.02). Conclusion: This study suggests that vigorous PA may affect IF reductions in obese men. © 2009 Elsevier Ireland Ltd. All rights reserved.

Recent molecular studies have shown that the genus Toxoptera is polyphyletic, and in particular that the name of the aphid known since 1952 as Toxoptera odinae (van der Goot) should revert to Aphis odinae (van der Goot), stat. rev. In this paper oviparae, alate males and fundatrices of A. odinae are described for the first time, from Japan. A. odinae is common as a grey-brown or rust-brown aphid on numerous plant species of shrubby habit throughout the Old World tropics and subtropics, but in temperate east Asia much darker forms occur, and Japanese populations of A. odinae include a dark green form not found elsewhere in the world. Multivariate morphometrics were used to confirm that both colour forms of the aphid in Japan were conspecific with samples from other parts of the world. Pergandeida kalopanacis Hori 1927 is a new synonym of A. odinae. Copyright © 2011 Magnolia Press.

Exercise intensity may induce changes in total adiponectin and adiponectin oligomer levels. However, the effects of acute aerobic exercise on total adiponectin and adiponectin oligomers in middle-aged abdominally obese men remain unknown. The purpose of this study was to investigate the influence of aerobic exercise intensity on changes in the concentrations of total adiponectin and adiponectin oligomers (high-molecular weight [HMW] and middle- plus low-molecular weight [MLMW] adiponectin), and the endocrine mechanisms involved in exercise-induced changes in adiponectin oligomer profiles in middle-aged abdominally obese men. Using a crossover design, 9 middle-aged abdominally obese men (age, 54.1 ± 2.4 years; body mass index, 27.9 ± 0.6 kg/m 2) underwent 2 trials that consisted of 60 minutes of stationary cycle exercise at either moderate-intensity (ME) or high-intensity (HE) aerobic exercise (50% or 70% of peak oxygen uptake, respectively). Blood samples were collected to measure the concentrations of adiponectin oligomers, hormones (catecholamines, insulin, and growth hormone), metabolites (free fatty acid, glycerol, triglyceride, and glucose), and cytokines (interleukin-6 and tumor necrosis factor-α). After exercise, plasma catecholamine concentrations were higher during HE than during ME (P < .05). Total adiponectin concentration decreased at the end of HE (P < .05), but remained unchanged after ME. The HMW adiponectin concentration did not change at either intensity, whereas the MLMW concentration decreased at the end of HE (P < .05). The ratio of HMW to total adiponectin concentration increased significantly (P < .05), whereas the ratio of MLMW to total adiponectin concentration decreased significantly (P < .05), at the end of HE. The percentage changes in epinephrine concentration from baseline to the end of exercise were correlated with the percentage changes in total adiponectin concentration (r = -0.67, P < .05) and MLMW adiponectin concentration (r = -0.82, P < .05) from baseline to the end of HE. Our results indicate that the change in total adiponectin was mainly due to a change in MLMW adiponectin concentration during high-intensity exercise in middle-aged abdominally obese men. Epinephrine may partially regulate the decrease in total and MLMW adiponectin concentrations during high-intensity exercise. © 2011 Elsevier Inc. All rights reserved.

Development of cardiovascular diseases could originate in early childhood. However, reference values of hemostatic parameters and adipokines in preschool children remain to be explored. We measured blood levels of adipokines and parameters of the hemostatic/fibrinolytic systems in 167 healthy children aged 4 to 6 years at 9:00 to 10:30 am after a strictly enforced overnight fast. Participants with body mass index (BMI) values ≥90th percentile had significantly higher values of systolic blood pressure and heart rate, as well as blood levels of insulin, coagulation factor (F) VII, FX, protein S, leptin, and homeostasis model assessment of insulin resistance (HOMA-IR), and lower values of desacyl-ghrelin than children with BMI < 90th percentile. Circulating levels of fibrinogen and leptin increased with increased number of cardiovascular risk factors. Stepwise regression analysis identified many hematological variables to be associated with features of the metabolic syndrome. The results implicated the hemostatic/fibrinolytic system or adipokines in the insidious progression of cardiovascular diseases from an early age. © SAGE Publications 2012.

[Purpose] The purpose of this study was to examine the effects of increasing physical activity on foot structure and ankle muscle strength in adults with obesity and to verify whether the rate of change in foot structure is related to that in ankle muscle strength. [Subjects and Methods] Twenty-seven adults with obesity completed a 12-week program in which the intensity of physical activity performed was gradually increased. Physical activity was monitored using a three-axis accelerometer. Foot structure was assessed using a three-dimensional foot scanner, while ankle muscle strength was measured using a dynamometry. [Results] With the increasing physical activity, the participants feet became thinner (the rearfoot width, instep height, and girth decreased) and the arch became higher (the arch height index increased) and stiffer (the arch stiffness index increased); the ankle muscle strength also increased after the intervention. Additionally, the changes in the arch height index and arch stiffness index were not associated with changes in ankle muscle strength. [Conclusion] Increasing physical activity may be one possible approach to improve foot structure and function in individuals with obesity.

The dropout rate in the self-selected weekly and bi-weekly class groups was lesser than that in the bi-weekly class group. Therefore, dietary sessions tailored to the needs of the participants might decrease the dropout rate.

Different characteristics of foot morphology are commonly accompanied by altering lower extremity biomechanical characteristics and foot function. Clarifying what factors affect foot morphology is helpful in understanding the basis of foot deformity and foot dysfunction.The aim of this study was to investigate characteristics of foot morphology and whether related factors such as gender, age, body mass index (BMI) and bilateral asymmetry have an impact on foot morphology.One hundred and eighty adults without exercise habit were included in this cross-sectional study. Participants were categorized by gender, age, BMI, and left and right foot respectively to compare foot morphology differences. The characteristics of foot morphology were measured using a 3D foot scanner.Compared with females, males had longer, larger and higher feet. In terms of age differences, older adults had shorter and stiffer feet. Regarding BMI differences, the value of height and width parameters of foot was larger, and the value of height of arch also larger in those with greater BMI. Regarding bilateral asymmetry, the right foot had a higher foot than the left foot. Multiple linear regression models indicated that gender, age and BMI significantly affected length and girth parameters of foot together.This study showed that gender has a bigger impact on length, width, height and girth parameters of foot than BMI or age. BMI has an impact on both arch height and stiffness. Besides, bilateral asymmetry affects values of height parameters of foot and arch.
