The plucking season of green tea leaves is one of the important parameters that decide their metabolic quality. Here, we performed the identification and quantity analysis of the metabolites of the green tea using NMR spectroscopy. We assigned the $^1H$ resonances for sixteen metabolites. This analysis found that four metabolites, gallic acid, quinic acid, theobromine and ECG, exhibited clear discrimination of green teas by the three different grades, Ujeon, Sejak and Jungjak. Our results suggest that these four metabolites could be used for diagnostics for quality control of green tea.

We have examined distribution and expression of caveolin-3 (cav-3), one of three caveolin isoforms from 16-wks-old spontaneously hypertensive rats (SHR) compared with age-matched control wistar-kyoto (WKY) rats. The expression of cav-3 was increased, whereas expression of PKB/Akt and calcineurin (Cn) was not changed in cardiac tissues of SHR compared to WKY rats. Interestingly, expression of cav-3, PKB/Akt and Cn were decreased in plasma membrane fraction in SHR compared to WKY rats. In H9c2 cardiomyoblast cells treated with phenylephrine ($50{\mu}M$, 48hr) or isoproterenol ($10{\mu}M$, 48hr), the expression of cav-3 was markedly enhanced compared to nontreated cells. Upon immunofluorescence analysis, cav-3 was localized in plasma membrane of control H9c2 cells. However phenylephrine or isoproterenol treatment caused translocation of cav-3 to perinuclear region. These results suggest that cav-3 plays as positive regulators in the development of hypertrophy in cardiac tissues of SHR rats.

Fatty liver is a common metabolic disorder of dairy cows during the transition period. Historically, the diagnosis of fatty liver has involved liver biopsy, biochemical or histological examination of liver specimens, and ultrasonographic imaging of the liver. However, more convenient and noninvasive methods would be beneficial for the diagnosis of fatty liver in dairy cows. The plasma metabolic profiles of dairy cows with fatty liver and normal (control) cows were investigated to identify new biomarkers using $^1H$ nuclear magnetic resonance. Compared with the control group, the primary differences in the fatty liver group included increases in ${\beta}$-hydroxybutyric acid, acetone, glycine, valine, trimethylamine-N-oxide, citrulline, and isobutyrate, and decreases in alanine, asparagine, glucose, ${\gamma}$-aminobutyric acid glycerol, and creatinine. This analysis revealed a global profile of endogenous metabolites, which may present potential biomarkers for the diagnosis of fatty liver in dairy cows.

The purpose of this study was to compare the quantitative and qualitative assessment of dietary intake between patients with metabolic syndrome (MetS) and healthy subjects and to investigate dietary factors related to MetS. Anthropometric measurements, blood analysis, and dietary intake as assessed by 24-hour recall were conducted in MetS patients (n=15) and healthy subjects (n=25). In order to assess the quantity and quality of dietary intake, daily nutrient intake, nutrient density, nutrient intake to dietary reference intake (DRI), nutrient adequacy ratio (NAR), food intake, dietary diversity score (DDS), and dietary variety score (DVS) were analyzed. The statistical differences between MetS patients and controls were analyzed using the SAS software program. Daily energy intake and food intake were not significantly different between the two groups (2,154.3 kcal vs. 1,872.9 kcal; 1,280.0 g vs. 1,261.6 g). There were also no significant differences in daily nutrient intake, nutrient intake ratio to DRI, NAR, or DVS between the MetS group and the control group. However, daily intake of eggs and milk in MetS patients was significantly lower than in the control group (9.0 g/day vs. 30.3 g/day, p<0.05; 0 g/day vs. 49.7 g/day, p<0.05). These results indicate that low intake of eggs and dairy products may be related to the development of MetS.

Drought is a major limiting factor that reduces rice production and occurs often especially under recent climate change. Plants have the ability to alter their developmental morphology in response to changing environment, which is known as phenotypic plasticity. In our previous studies, we found that one chromosome segment substitution line (CSSL50 derived from Nipponbare and Kasalath crosses) showed no differences in shoot and root growth as compared with the recurrent genotype, Nipponbare under non-stress condition but showed greater growth responses compared with Nipponbare under mild drought stress condition. We hypothesized that reducing root respiration as metabolic cost, which may be largely a consequence of aerenchyma formation would be one of the key mechanisms for root plasticity expression. This study aimed to evaluate the root respiration and aerenchyma formation under various soil moisture conditions among genotypes with different root plasticity. CSSL50 together with Nipponbare and Kasalath were grown under waterlogged conditions (Control) and mild drought stress conditions (20% of soil moisture content) in a plastic pot ($11cm{\times}14cm$, ${\varphi}{\times}H$) and PVC tube ($3cm{\times}30cm$, ${\varphi}{\times}H$). Root respiration rate was measured with infrared gas analyzer (IRGA, GMP343, Vaisala, Finland) with a closed static chamber system. There was no significant difference between genotypes in control for shoot and root growth as well as root respiration rate. In contrast, all the genotypes increased their root respiration rates in response to mild drought stress. However, CSSL50 showed lower root respiration rate than Nipponbare, which was associated by higher root aerenchyma formation that was estimated based on internal gas space (porosity) under mild drought stress conditions. Furthermore, there were significant negative correlations between root length and root respiration rate. These results imply that reducing the metabolic cost (= root respiration rate) is a key mechanism for root plasticity expression, which CSSL50 showed under mild drought.

Purpose: The aim of this study was to examine the effects of obesity on the physiological levels of adiponectin, leptin and components of metabolic syndrome (MS) in male workers, aged 30-40 years. Methods: Body mass index (BMI) was measured with Anthropometric equipment. Blood pressure and serum parameters were measured with an automatic digital sphygmomanometer and autochemical analyzer, respectively. Adiponectin and leptin were analysed by ELISA kits and MS was defined based on the NCEP-ATP III. Results: Body fat mass of waist and hip, systolic and diastolic blood pressure were significantly higher, as expected, in the BMI>25kg/$m^2$ in comparison with the $BMI{\leq}25kg/m^2$. While fasting glucose, insulin, HOMA-IR and leptin in the BMI>25kg/$m^2$ were also significantly higher compared with $BMI{\leq}25kg/m^2$, HDL-cholesterol and adiponectin were significantly higher in $BMI{\leq}25kg/m^2$. On multiple logistic regression analysis for the components of MS, exercise, adiponectin and leptin were an only independent factor for MS in non-obese male workers($BMI{\leq}25kg/m^2$) after adjustment for age, cigarette smoking and drinking habits. Conclusion: These results suggested that the obesity in men was associated with physiological levels of adiponectin and leptin contributing to feedback control of MS and that dysfunction and/or declination in feedback control system associated with changes in physiological levels of neurptrophics: adiponectin and leptin might ultimately induce MS.

The purpose of this study was to investigate the relationship between coffee intake and metabolic syndrome, which has increased the burden of social illness, based on the data of the $6^{th}$ National Health and Nutrition Survey in 2015. The subjects' coffee intake level was divided into <1 cup/a day, 1~2 cups/a day, and ${\geq}3cups/a\;day$ and the general characteristics of the subjects were examined according to the classification. The effect of coffee consumption on the risk factors of metabolic syndrome was evaluated by OR value. The age of the subjects was higher than that of the other groups in the < 1 cup/day group and the TG in the prediabetic group was above the normal level in the ${\geq}3cups/day$ group. In the normal group of blood glucose, coffee intake was the highest in <1 cup/day group and BP was significantly different according to intake. In the multiple regression analysis conducted to identify the causal relationship between the risk of metabolic syndrome and coffee intake, BP was significantly decreased in ${\geq}3cups/day$ coffee group in normal group. In order to control the level of blood lipids in pre-diabetic subjects, it is necessary to establish dietary guidelines for foods that are frequently consumed, and various situations and long-term studies are needed to determine the precise effect of coffee intake on BP.

BACKGROUND/OBJECTIVES: Nutritional status and food intake during pregnancy and lactation can affect fetal programming. In the current metabolic syndrome epidemic, high-fructose diets have been strongly implicated. This study investigated the effect of maternal high-fructose intake during pregnancy and lactation on the development of metabolic syndrome in adult offspring. SUBJECTS/METHODS: Drinking water with or without 20% fructose was administered to female C57BL/6J mice over the course of their pregnancy and lactation periods. After weaning, pups ate regular chow. Accu-Chek Performa was used to measure glucose levels, and a tail-cuff method was used to examine systolic blood pressure. Animals were sacrificed at 7 months, their livers were excised, and sections were stained with Oil Red O and hematoxylin and eosin (H&E) staining. Kidneys were collected for gene expression analysis using quantitative real-time Polymerase chain reaction. RESULTS: Adult offspring exposed to maternal high-fructose intake during pregnancy and lactation presented with heavier body weights, fattier livers, and broader areas under the curve in glucose tolerance test values than control offspring. Serum levels of alanine aminotransferase, aspartate aminotransferase, glucose, triglycerides, and total cholesterol and systolic blood pressure in the maternal high-fructose group were higher than that in controls. However, there were no significant differences in mRNA expressions of renin-angiotensin-aldosterone system genes and sodium transporter genes. CONCLUSIONS: These results suggest that maternal high-fructose intake during pregnancy and lactation induces metabolic syndrome with hyperglycemia, hypertension, and dyslipidemia in adult offspring.

Objectives: Ssanghwa-tang (SHT) is a traditional herbal formula comprising nine medicinal herbs, and it is used for reducing fatigue in Korea. SHT exerts various effects such as anti-inflammatory, antioxidant, and anti-aging activities, and protection against acute hepatotoxicity. However, the genotoxicity of SHT has not yet been established. Methods: Ten components were identified in SHT water extract by using high-performance liquid chromatography analysis. We assessed the genotoxicity of SHT by using bacterial reverse mutation (Ames test), chromosome aberration, and in vivo micronucleus tests. Results: The contents of paeoniflorin, glycyrrhizin, and liquiritin apioside in SHT were 15.57, 6.94, and 3.48 mg/g extract, respectively. SHT did not increase the revertant colonies of Salmonella typhimurium and Escherichia coli strains in the presence or absence of metabolic activity. Although SHT did not induce structurally abnormal chromosomes in Chinese hamster lung (CHL) cells in the presence of metabolic activity, the number of structurally aberrated chromosomes increased dose-dependently in the absence of metabolic activity. In the in vivo micronucleus test, SHT did not affect the formation of micronuclei compared with the vehicle control. Conclusions: Genotoxicity of SHT was not observed in the Ames test and in vivo micronucleus test. However, based on the results of chromosome aberration test, it can be presumed that SHT has the potential to induce genotoxicity because it induced structurally abnormal chromosomes in the absence of metabolic activity.
