Objectives: This study identified biopsychosocial factors associated with metabolic syndrome among Korean men and women aged over 40 years. Methods: Secondary data from the 2010-2016 Korean National Health and Nutrition Examination Survey were used for this study. Based on the biopsychosocial model, psychosocial factors (stress, depression, smoking, binge alcohol consumption, physical activity) were assessed with control of biomedical (age, body mass index, family history of hypertension, dyslipidemia, type 2 diabetes mellitus, and cardiovascular disease) and biosocial factors (educational level and economic status). Data from 8,624 men and 7,321 women were analyzed by logistic regression analysis using a complex sample procedure. Results: Among men, current or past smoking habits (Adjusted Odds Ratio [AOR]: 1.349; 95% Confidence Interval [CI]: 1.155-1.575, p<.001) and binge alcohol consumption (AOR: 1.570, CI: 1.389-1.774, p<.001) were associated with metabolic syndrome. In addition, moderate (AOR: 1.205, CI: 1.038-1.400, p=.014) and low levels of physical activity (AOR: 1.296, CI: 1.109-1.514, p=.001) were associated with metabolic syndrome. Among women, low level of physical activity (AOR: 1.276, CI: 1.017-1.602, p=.036) was associated with metabolic syndrome. Conclusion: Gender specific interventions such as encouraging physical activity and prevention of smoking and excessive alcohol drinking are important to prevention of metabolic syndrome.

Yoga has been known to have stimulatory or inhibitory effects on the metabolic parameters and to be uncomplicated therapy for obesity. The purpose of the present study was to test the effect of an 8-week of yoga-asana training on body composition, lipid profile, and insulin resistance (IR) in obese adolescent boys. Twenty volunteers with body mass index (BMI) greater than the 95th percentile were randomly assigned to yoga (age $14.7{\pm}0.5$ years, n=10) and control groups (age $14.6{\pm}1.0$ years, n=10). The yoga group performed exercises three times per week at 40~60% of heart-rate reserve (HRR) for 8 weeks. IR was determined with the homeostasis model assessment of insulin resistance (HOMA-IR). After yoga training, body weight, BMI, fat mass (FM), and body fat % (BF %) were significantly decreased, and fat-free mass and basal metabolic rate were significantly increased than baseline values. FM and BF % were significantly improved in the yoga group compared with the control group (p<0.05). Total cholesterol (TC) was significantly decreased in the yoga group (p<0.01). HDL-cholesterol was decreased in both groups (p<0.05). No significant changes were observed between or within groups for triglycerides, LDL-cholesterol, glucose, insulin, and HOMA-IR. Our findings show that an 8-week of yoga training improves body composition and TC levels in obese adolescent boys, suggesting that yoga training may be effective in controlling some metabolic syndrome factors in obese adolescent boys.

대사 공학을 이용한 생산 균주 개발의 핵심 기술은 원하는 대사산물을 과량으로 얻기 위하여 기존의 대사회로에서 제거, 증폭, 변경을 시켜야 할 유전자를 선정하는 것이다. 대사조절 분석 기법은 대사 흐름이 특정 효소의 활성에 따라 어떻게 변하는지를 예측하는 기술이다. 본 논문에서는 대장균의 threonine 생합성 효소 반응 kinetic model과 대사조절 분석 기법을 이용하여 threonine 생합성 flux를 가장 효과적으로 증가시키기 위하여 활성 증가가 필요한 효소가 aspartate semialdehyde dehyogenase라는 것을 밝혔다. 이러한 결과를 확인하기 위하여 asd가 과발현된 vector와 threonine 생합성 경로의 다른 효소인 aspartate kinase를 coding하는 thrA를 과발현 시키는 vector를 제작하여 threonine 생산 균주인 TF5015에 형질전환하여 threonine 농도를 측정하였다. Flask 배양결과 대사조절 분석 기법으로 확인된 유전자 asd를 과발현시킬 경우가 생합성 경로의 다른 유전자를 과발현시킨 경우보다 더 높은 threonine 농도의 증가를 보였다. 이러한 연구 결과들은 효소 반응 kinetic model과 대사조절 분석 기법을 이용하여 원하는 product를 효율적으로 생산할 수 있는 생산 균주를 제작할 수 있게 할 것이다.

Objectives: The objective of this study is to develop a new animal model with Kidney-hypofunction for Sasang Constitutional Medicine, especially for partial Soyangin(one of four constitution which has good digestive function and poor renal function) by Unilateral Ureteral Obstruction, and to estimate the factor related to obesity, dyslipidemia, and metabolic syndrome. Methods: The C57BL/6J mice were divided into 3 groups : normal group, high fat diet(HFD) control group, and HFD group with Unilateral Ureteral Obstruction(UUO). Then, the HFD control group and the experimental group were fed with high fat diet for 6 weeks. Food intake and body weight were measured at regular time by week. After the final experiment, blood was gathered for bloodchemical examination and organs(liver, fatty tissue) were remoed, weighted, and mRNA was analyzed with real-time PCR. Results: The weight growth rate with High fat diet went down by 8.35% in experimental group and had similar FER with the normal group, while HFD control group had higher weight growth rate and FER than any other groups. Also The experimental group had lower triglyceride and LDL cholesterol rate and higher glucose rate in serum. and in mRNA expression, GLUT-9, the protein related to excretion of uric acid and metabolic syndrome, expressed lower rate than that of HFD control group. and IL-6, a kind of cytokine related to obesity and metabolic syndrome, expressed more than HFD control group. Conclusions: It was found that Kidney-hypofunction animal-experimental model is susceptible to metabolic syndrome.

Purpose: This study was done to determine the effects of walking exercise training(WET) on metabolic syndrome risk factors and body composition in obese middle school girls. Method: A non-equivalent pretest-posttest experimental design was used. Twenty seven subjects participated in this study from one women's middle school in Busan. The participants were purposely allocated to an experimental group (n=14) and a control group (n=13). The experimental group participated in 30-60 minutes of WET with 55 to $75\%$ of a maximal heart rate six days a week for 12 weeks. Results: The prevalence of individual risk factors on metabolic syndrome were improved in the experimental group after the intervention. The high waist circumference(WC), high triglyceride(TG), low high density lipoprotein cholesterol(HDL-C), high blood pressure(BP) and high fasting glucose(FG) were 21.4, 21.4, 14.3, 28.6 and $7.2\%$, respectively. There were significant differences in WC (F=22.24, p<.001), TG (F=5.34, p=0.30), body weight(F=21.99, p<.001), fat mass(F=19.17, p<.001), and $\%$ body fat(F=17.93, p<.001) between the experimental and control group after the intervention. However, there were no significant differences in HDL-C, FG and BP between the experimental and control group after the intervention. Conclusion: These results indicate that WET is effective in decreasing risk factors of the metabolic syndrome and body composition components in obese middle school girls. These findings suggest that WET can be useful as a nursing intervention in the prevention of obesity-related disorders in obese adolescents.

Various processing methods have a great impact on the physiochemical and nutritional properties of meat that are of health concern. Hence, the postmortem processing of meat by different methods is likely to intensify the potential effects on protein oxidation. The influence of meat protein oxidation on the modulation of the systemic redox status and underlying mechanism is well known. However, the effects of processed meat proteins isolated from different sources on gut microbiota, oxidative stress biomarkers, and metabolomic markers associated with metabolic syndromes are of growing interest. The application of advanced methodological approaches based on OMICS, and mass spectrometric technologies has enabled to better understand the molecular basis of the effect of processed meat oxidation on human health and the aging process. Animal studies indicate the involvement of dietary proteins isolated from different sources on health disorders, which emphasizes the impact of processed meat protein on the richness of bacterial taxa such as (Mucispirillum, Oscillibacter), accompanied by increased expression of lipogenic genes. This review explores the most recent evidences on meat processing techniques, meat protein oxidation, underlying mechanisms, and their potential effects on nutritional value, gut microbiota composition and possible implications on human health.
