Purpose: The purpose of this study was to identify the levels of physical activity and its relationships with depression, health-related quality of life (QoL), sleep disturbance, and physiological indicators in hemodialysis patients. Methods: The participants in this study were 139 patients undergoing hemodialysis in the hospitals in Busan and Yangsan-si. Data were collected using hematologic tests and questionnaires that contained items about individual characteristics, International Physical Activity Questionnaires (IPAQ), Center For Epidemiological Studies Depression Scale (CES-D), a 12-item Short-Form Health Survey (SF-12), and Pittsburgh Sleep Quality Index (PSQI). Data were analyzed using descriptive statistics, one way ANOVA, and correlation. Results: Mean age of the participants was $59.91{\pm}12.63$ and mean physical activity levels were $1,660.35{\pm}1,654.17$. Patients who performed higher physical activities during their daily activities reported lower levels of depression (F=4.16, p=.018) and higher levels of QOL (PCS: F=5.00, p=.008, MCS: F=8.66, p<.001) than those of the others who did not perform physical activities. Conclusion: This study showed that the levels of physical activity among hemodialysis patients was significantly associated with their depression and QOL. Developing strategies for enhancing physical activity is warranted to improve depression and QOL among hemodialysis patients.

The purpose of this study was to analyze the relationships among zinc status, diet quality, glycemic control and self-rated physical activity level of type 2 diabetic patients. Dietary intakes for two non-consecutive days were measured by 24-hour recall method for seventy-six diabetic patients. Fasting blood glucose and HbA1c were measured for the assessment of glycemic control. We evaluated the extent of dietary adequacy by the percentage of subjects with a dietary intake of a nutrient less than the estimated average requirement(EAR), the dietary diversity score(DDS) and the dietary variety score(DVS). Zinc status was assessed from serum levels and urinary excretion. Dietary inadequacy was serious for five nutrients: riboflavin, calcium, thiamin, zinc and vitamin C. Dietary intakes from the meat, fish, and egg food groups and the milk food group were below the recommended level. We found that subjects with high levels of physical activities had significantly higher DVS and serum zinc levels compared to others (p

BACKGROUND/OBJECTIVES: One ongoing effort to curtail dyslipidemia in school children is through lifestyle intervention. This study analyzes outcomes of the intervention of nutrition education and Javanese traditional game-based physical activity, on lipid profiles of overweight and obese children. SUBJECTS/METHODS: The experimental study consisted of three steps: data collection (October to December 2016), intervention processes (January to March 2017), and final report preparation (April to May 2017). This was a split-plot block study, enrolling a total of 72 subjects. Traditional game intervention (12 meetings) and nutrition education (9 meetings) was carried out within 3 months with material related to obesity. RESULTS: Our results showed no decrease in the levels of total cholesterol in the group receiving nutrition education (rise by 1.56 mg/dL), but when compared to subjects without intervention, total cholesterol levels experienced was increased. The group which did not receive physical activity showed increase in the total cholesterol, whereas the traditional game intervention group showed a decrease of 0.05 mg/dL total cholesterol at the end of the intervention. Nutrition education and physical activity interventions did not influence any reduction in the low-density lipoprotein cholesterol (LDL-C) levels, but rather showed a tendency to increase at the end of the intervention. However, the increase in LDL-c levels in the traditional game group was lower than in other intervention groups. Duncan's test indicated that the effect of nutrition education and physical activity interventions did not differ from the cut-off values of LDL-C and high-density lipoprotein cholesterol. CONCLUSIONS: Total cholesterol and triglyceride levels in the traditional game group tended to decrease at the end of the intervention, but the results did not differ much from other intervention groups. We deduce that nutrition education and traditional game-based physical activity interventions are not capable of improving blood lipid profiles in overweight and obese children within 3 months. It is necessary to increase the time of physical activity intervention to maintain the lipid profile in another study.

Water extract from Cnidii Rhizoma (CRW) was tested for colon cancer chemopreventive activity by measuring the induction of phase II detoxification enzyme activity [quinone reductase (QR) and glutathione S-transferase (GST)] and glutathion (GSH) levels and ornithine decarboxylase (ODC) activity in cultured human colorectal adenocarcinoma HT-29 cells. CRW inhibited cell proliferation in cultured HT-29 cells. CRW induced QR activity in a dose-dependent manner in a concentration range of 0.1${\sim}$5.0 $mg/m{\ell}$. GST activity was also induced with the treatment of CRW in HT-29 cells. In addition GSH levels was increased with CRW. CRW inhibited ODC activity, a key enzyme of polyamine biosynthesis, which is enhanced in tumor promotion. These results suggest that CRW has colon cancer chemopreventive activity by increasing phase II enzyme activity and GSH levels and inhibiting ODC activity in vitro.

The induction of hepatic cytochromes P450 and metabolic effects have been examined in male and female Sprague-Dawley rats following treatment with either phenobarbital or 3-methylcholanthrene. Hepatic cytochrome P450 levels were higher in males than in females by ~40%. Treatment of male and female rats with phenobarbital or 3-methylcholanthrene resulted in an ~1.6 and 2-fold increase, respectively, in heptic microsomal cytochrome P450 levels in both sexes, relative to untreated animals. Immunoblot analyses were performed to compare sex-related changes in P450 levels. Hepatic P45IIB1 levels in males were greater than those in females following phenobarbital treatment. 3-Methylcholanthrene-induced male hepatic microsomes exhibited greater levels of P450 females failed to exhibit a band. Mab PCN 2-13-1 against P-45-IIIA recognized an intense in uninduced microsomes from female rats. The levels of P450IIIA in males were increased 2 to 3-fold following treatment with phenobarbital, while the increase of IIIA levels in females by phenobarbital was minimal, as monitored by immunoblot analysis. Solid phase radiommunoassay using monoclonal antibodies supported the results of immunoblot analysis. Phenobarbital treatment caused a 6.5-fold increase in the monoclonal iantibody binding to IIBI in males, whereas treatment of females with phenobarbital resulted of IA levels by 3-methylcholanthrene was also greater in females than in males (10-vs. 8-fold) although the levels of induced IA were comparable inboth sexes, as assessed by radiommunoassay. Radioimmunoassay also showed that hepatic IIEI level was 1.5-fold higher in males than in females and that either phenobarbital or 3-methylcholanthrene treatment caused 80% to 40% decrease in IIEL levels, relative to control, in both sexes. Sex-related metabolic activities were examined in hepatic microsomes. Hexobarbital hydroxylase activity was 2-to 3-fold higher in uninduced microsomes from males than that from females. This hydroxylase activity was increased 2-and 3-fold in males and females, respectively, following phenobarbital treatment, as compared to controls. Addition females produced 64% and 84% inhibition of hexobarbital oxidation, respectively. Aryl hydrocarbon hydroxylase activity was increased -12 and 26-fold in males and females respectively. Following phenobarbital treatment, as compared to controls. Addition of anti-P450IIB1 antibody to phenobarbital-induced hepatic microsomes from males and females produced 64% and 84% inhibition of hexobarbital oxidation, respectively. Aryl hydrocarbon hydroxylase activity was increased -12 and 26 fold in males and females, respectively, following 3-methylcholanthrene treatment relative to controls. The anti-P-450IA antibody inhibitable rate of aryl hydrocarbon hydroxylase activity was comparable in both sexes following 3-methylcholanthrene treatment relative to controls. The anti-P450LA antibody inhibitable rate of aryl hydrocarbon hydroxylase activity was comparable in both sexes following 3-methylcholanthrene treatment (-70%). These results demonstrate that levels of hepatic P450IIB1 or P450IA are greater in male than in female for untreated, phenobarbital-or-3-methylcholanthrene treated rats. In addition, the relative for untreated phenobarbital-or 3-methylcholanthrene treated rats. In addition, the relative increase of phenobarbital-or 3-methylcholanthrene treated rats. In addition, the relative increase of phenobarbital-or 3-methylcholanthrene treated rats. In addition, the relative increase of P450IIB1 or IA phenobarbital or 3-methylcholanthrene is more significant in females.

The effects of $\beta$-carotene substitutionl for vitamin A and the chronic consumption of ethanol of ethanol on hepatic folate metabolism were studied it rats. The substitution of $\beta$-carotene for vitamin A depressed hepatic 10-formyl-tetreahydrofolate dehydrogenase(10-formyl-tetrahydrofolate : NADP oxidoreductase, E.C. 1.5. 1.6)activity to 65% of controls(p<0.001) and enhanced hepatic 5, 10-methy-lenetetrahydrofolate reductase(E. C. 6.3.3.2)activity by 56% with respect to control levels(p<0.001). Hepatic activity of 10-formyltertrahydrofolate dehydrogenase was depressed to about half that of control levels by ethanol administration to rats(36% ethanol diet, p<0.001). The activity of 5, 10-methyleneterahydrofolate reductase was not changed by ethanol consumption. The increased activity of 5, 10-methyleneterahydrofolate reductase and the decreased activity of 10-formyltetrahydrofolate dehydrogenase appeared to decrease the level of nonmethyl folate conezyme and the rate of one-carbon metabolism. Plasma homocysteine concentrations were significantly higher in rats fed ethanol(p<0.01) o $\beta$-carotene(p<0.001) than in controls, which suggests that increased activity of 5, 10-methylenetetrahydrofolate reductase can depress homocysteine metabolism. We concluded that dietary substitution of $\beta$-carotene for vitamin A or chronic administration of ethanol resulted in changes in the activity of hepatic folate-dependent enzymes, which could affect the distribution of folate derivatives, plasma homocysteine levels and one-carbon metabolism.

Purpose: This study was done to identify the impact of physical activity on healthcare utilization among Korean adults. Methods: Drawing from the 2008 Korean National Health and Nutrition Examination Survey (NHANES IV-2), data from 6,521 adults who completed the Health Interview and Health Behavior Surveys were analyzed. Association between physical activity and healthcare utilization was tested using the $X^2$-test. Multiple logistic regression analysis was used to calculate the odds ratios of using outpatient and inpatient healthcare for different levels of physical activity after adjusting for predisposing, enabling, and need factors. A generalized linear model applying a negative binomial distribution was used to determine how the level of physical activity was related to use of outpatient and inpatient healthcare. Results: Physically active participants were 16% less likely to use outpatient healthcare (OR, 0.84; 95% CI, 0.74-0.97) and 23% less likely to use inpatient healthcare (OR, 0.77; 95% CI, 0.63-0.93) than physically inactive participants. Levels of outpatient and inpatient healthcare use decreased as levels of physical activity increased, after adjusting for relevant factors. Conclusion: An independent association between being physically active and lower healthcare utilization was ascertained among Korean adults indicating a need to develop nursing intervention programs that encourage regular physical activity.

Levels of quercetin in different parts of onion were investigated using high performance liquid chromatography (HPLC) and liquid chromatography mass spectrometry (LC/MS) suitable for use with functional food material. Two main peaks were observed on HPLC chromatograms from the extracts of the skin, and the outer, middle, and core parts of onion. Using LC/MS, peak 1 was tentatively identified as quercetin monoglucoside at m/z 466.4, and peak 2 as quercetin with [M]+ at m/z 303.3. The levels of quercetin in the skin, and the outer, middle and core parts of the plant were 16.83,2.67,0.95, and 0.35 mg/g, respectively. In the study of 1,1-diphenyl-2-picrylhydrazyl (DPPH) radical scavenging activity, skin, the nonedible part, contained the highest amount of quercetin, compared to the other edible parts, and showed the highest DPPH radical scavenging activity. Levels of quercetin and DPPH radical scavenging activity increased from core to skin. All parts of onion exhibited the strongest antibacterial activity only against Staphylococcus aureus and Vibro parahaemolyticus. Antibacterial activities of onion exhibited that S. aureus was more sensitive than V. parahaemolyticus. Among the four onion extracts, the middle part showed the strongest inhibitory activity against S. aureus but all onion extracts showed similar antibacterial activities against V. parahaemolyticus.

Background: It is difficult to assess whether community-dwelling frail older adults may remain pre-frail status or improve into a robust state without being directly checked by health care professionals. The health information perceived by older adults is considered to be one of best sources of potential concerns in older adult population. An online measurement system combined with item response theory (IRT) and computer adaptive testing (CAT) methods is likely to become a realistic approach to remotely monitor physical activity status of frail older adults. Objects: This article suggests an approach to provide a precise and efficient means of measuring physical activity levels of community-dwelling frail older adults. Methods: Article reviews were reviewed and summarized. Results: In comparison to the classical test theory (CTT), the IRT method is empirically aimed to focus on the psychometric properties of individual test items in lieu of the test as a whole. These properties allow creating a large item pool that can capture the broad range of physical activity levels. The CAT method administers test items by an algorithm that select items matched to the physical activity levels of the older adults. Conclusion: An online measurement system combined with these two methods would allow adequate physical activity measurement that may be useful to remotely monitor the activity level of community-dwelling frail older adults.
