Blueberry (BB), fruit of Vacciniumi, has been hailed as an antioxidant superfood. BB is a rich source of vitamins, minerals, flavonoids, phenolic acids and known to have a variety of pharmacological actions. The purpose of this work is to clarify the anti-inflammatory mechanism of BB in lipopolysaccharide (LPS)-activated RAW264.7 macrophage. We explored the effects of BB on the production of inflammatory cytokines, prostaglandin E2 (PGE2) and expression of cyclooxygenase (COX)-2 in LPS-activated RAW264.7 macrophage. Moreover, to investigate the molecular mechanisms by BB, we evaluated whether BB modulate nuclear factor-kappa B (NF)-kB pathway and caspase- 1 activation. The findings of this work demonstrated that BB alleviated the LPS-enhanced inflammatory cytokines and PGE2, as well as COX-2 levels. Additionally, we demonstrated that the anti-inflammatory mechanism of BB occurs due to the attenuation of IκB-α degradation, NF-kB translocation and caspase-1 activation. Conclusively, these findings provide evidence that BB may be useful agents in the treatment of inflammation.
Purpose: This study was designed to investigate whether nutritional supply influences biochemical markers and clinical outcomes in patients who received continuous renal replacement therapy (CRRT) by evaluating adequacy of nutritional supply for patients. Methods: From January 2012 to December 2013, 239 adult patients who received CRRT in the intensive care unit for more than 3 days were included. General information from electronic medical records and nutritional status related biochemical data and clinical outcomes on the first day of CRRT and 2 weeks after CRRT were collected. Results: The rate of delivered energy and protein was 68.06% and 43.13% which was much lower than energy and protein supply based on their requirement. When the patients were divided into two groups according to 70% of energy received rate and 50% of protein received rate, the group with more than 70% of energy received rate showed significant decrease of length of hospital stay (p = 0.007), length of stay in intensive care unit (ICU) (p = 0.008), duration of CRRT (p < 0.001), and APACHE II score (p < 0.001) compared to less than 70% of energy received rate after adjusting for age. In addition, the group with more than 50% of protein received rate showed decreased mortality (p = 0.031), length of hospital stay (p = 0.008), length of ICU stay (p = 0.035), duration of CRRT (p < 0.001), and APACHE II score (p < 0.001) after adjusting for age. We found that the level of hematocrit (p = 0.006) was significantly improved in the group with more than 70% of energy received rate, and the level of TLC (p = 0.049), hematocrit (p = 0.041) was significantly improved in the group with more than 50% of protein received rate. We also found that energy delivery was negatively correlated with length of stay in ICU (p = 0.049) and positively correlated with level of calcium (p = 0.037). In addition, protein delivery was correlated with the levels of serum total protein (p = 0.021), serum albumin (p = 0.048), hematocrit (p = 0.009), and total cholesterol (p = 0.021) when dead patients were included, but was correlated with the levels of hematocrit (p = 0.034) and calcium (p = 0.024) when dead patients were excluded. Conclusion: Proper nutritional delivery may help patients' clinical outcomes for patients receiving CRRT. However, their actual intakes of energy and protein were not adequate for their requirements. Identification of patients with malnutrition is necessary and a multidisciplinary approach for systemic management is also required.

This study aimed to determine the effects of freeze-dried onion powder (OP) which contains rich in quercetin (22 mg/10 g) on hyperlipidemic participants. Fourteen participants (total cholesterol level in plasma $270.8{\pm}21.4mg/dL$) $40{\sim}59$ years of age who were diagnosed as hyperlipidemia by a physician at Fatima Hospital in Changwon took part in this study for 12 weeks. We investigated the anthropometric data and dietary habit by using questionnaires. Also, blood samples were collected from the patients in fasting before and after this 12 weeks intervention study. 78.6% of the patients showed interest in health diet management and weight control; however, they also showed some problems in their dietary habit (meal irregularity, food choice, calorie nutrient balance, high fat and cholesterol etc.) and life style (smoking, eating out, alcohol intake) that could have adverse effect on hyperlipidemic therapy. Most participants (85.7%) thought that OP was good for their health. The total cholesterol and LDL-cholesterol significantly decreased with OP intake. The HDL-cholesterol increased and the Atherogenic index (AI) significantly decreased. Regarding the correlations of dietary habit and life style with anthropometric and biochemical factors, the alcohol intake level was significantly correlated with the frequency of eating out and body mass index (BMI). Exercise level showed positive correlation with HDL-cholesterol and negative correlation with atherogenic index (AI). These results suggest that the intake of polyphenol rich onion may decrease the risk of hyperlipidemia by reducing cholesterol level. We consider these hypolipidemic effects of OP as a possible functional food. However, further research such as a well designed longterm clinical study with experimental and placebo groups is needed.

The purpose of this study was to investigate students' and parents' perceptions of nutrition education. In this survey, 7,577 elementary school students and 6,003 of their parents across the country were surveyed about the necessity of implementing nutrition education, its present status and problems and future methods for nutrition education implementation. The results showed that 96.6% of the parents and 62.8% of the students responded that nutrition education was urgently needed, at least once per week in the lower grades of elementary school, and that it should be related to and coordinated with special activities class. In addition, the survey showed that students and their parents wanted nutrition teachers to establish a nutrition counseling room, a practical cooking class, a special activity class, and/or dietary camp during school breaks. With regard to the status of nutrition education at home, there was statistical evidence that suggests significant differences between urban and rural schools. Approximately 63% of the parents indicated that they had difficulty teaching nutrition education in their own homes, because it was difficult to determine the dietary habits and nutritional status of their children. When asked about attending a dietary class for parents, 74% expressed their intent to attend. Parents were most interested in learning about cooking practices, diet therapy, and food information in that order. The results showed that the most effective method of dietary education was to teach appropriate nutritional practices in school and at home simultaneously. Hence, necessary information and education should be provided through special lectures, special cooking classes, and dietary classes for parents. The conclusions of this study suggest that a variety of education programs should be developed to achieve effective nutrition education for students and their parents.

The Akt/mammalian target of the rapamycin (mTOR) pathway is activated in the majority of human cancers. Activation of the Akt/mTOR pathway confers resistance to many types of cancer therapy. In this study, we evaluated the apoptotic effect of ethanol extract of Artemisia annua L. through down-regulation of Akt signal pathways and the mitochondrial pathway in hepato-carcinoma cells (HepG2). A. annua extract is known as a medicinal herb that is effective against cancer. We evaluated anti-proliferative activity by MTT-based viability assay and apoptotic effect by Annexin-V/PI staining, mitochondrial membrane potential (MMP), and caspase-3/7 activity as determined by flow cytometry. A. annua treatment led to loss of MMP, resulting in cytochrome c-inducible activation of caspase-3/7. Treatment with A. annua extract reduced activities of Akt/mTOR/anti-apoptotic proteins (such as Bcl-2 and $Bcl-X_L$), leading to increased activation of tumor suppressor p53 and pro-apoptotic proteins (such as Bax and Bak). We applied LY294002 (inhibitor of Akt) and rapamycin (inhibitor of mTOR) to determine the relationship between signal transduction of proteins associated with apoptosis. LY294002 and rapamycin significantly reduced cell viability and increased apoptosis. These results indicate that Bcl-2 and caspase-3 are key regulators in A. annua extract-induced apoptosis in HepG2 cells and are controlled through the Akt/mTOR signaling pathway.
Objectives: The aim of this study was to examine self-management status, nutritional knowledge, barrier factors in dietary management and needs of nutritional management program for women with Gestational Diabetes Mellitus (GDM). Methods: A total of 100 women with GDM were recruited from secondary and tertiary hospitals in Seoul. The questionnaire composed of general characteristics, status of self-management, dietary habits, nutrition knowledge, barrier factors in dietary management, needs for nutrition information contents and nutritional management programs. Data were collected by a self-administered questionnaire. All data were statistically analyzed using student's t-test and chi-square test using SAS 9.3. Results: About 35% of the subjects reported that they practiced medical nutrition and exercise therapy for GDM control. The main sources of nutrition information were 'internet (50.0%)' and 'expert advice (45.0%)'. More than 70% of the subjects experienced nutrition education. The mean score of nutrition knowledge was 7.5 point out of 10, and only about half of the subjects were reported to be correctly aware of some questions such as 'the cause of ketosis', 'the goal of nutrition management for GDM', 'the importance of sugar restriction on breakfast'. The major obstructive factors in dietary management were 'eating more than planned when dining out', 'finding the appropriate menu when dining out'. The preferred nutrition information contents in developing management program were 'nutritional information of food', 'recommended food by major nutrients', 'the relationship between blood glucose and food', 'tips on menu selection at eating out'. The subjects reported that they need management program such as 'example of menu by calorie prescription', 'recommended weight gain guide', 'meal recording and dietary assessment', 'expert recommendation', 'sharing know-how'. Conclusions: Based on the results of this study, it is necessary to develop a program that provide personalized information by identifying the individual characteristics of the subjects and expert feedback function through various information and nutrition information contents that can be used in real life.
Takju was manufactured using 150 g Rosa rugosa Thunb. (Haedanghwa) and two different preparations of 3,000 g each of cooked and uncooked rice. Nuruk (150 g) and yeast (60 g) were inoculated into both mixtures for fermentation, and physiochemical changes were investigated during 14 days of fermentation. The final brix value, pH, and ethanol concentration of Haedanghwa (uncooked rice Takju) were $13.0^{\circ}$Bx, 4.3, and 11.8%, respectively, whereas those of Haedanghwa (cooked rice Takju) were $14.0^{\circ}$Bx, 4.6, and 14.4%, respectively. Lactic and acetic acid levels in Haedanghwa (uncooked rice Takju) were significantly higher than those in Haedanghwa (cooked rice Takju) (p<0.05). The level of ${\gamma}$-amino-n-butyric acid in Haedanghwa Takju (uncooked rice) was twice than that of Haedanghwa Takju (cooked rice). Our results demonstrate that the use of uncooked rice in the preparation of Takju may help improve the taste and function of the final product.

Purpose: This study evaluated the effects of nutrition management application in a mobile device on obesity management of patients with breast cancer. Methods: Fifty subjects, who were breast cancer survivors, aged 30 years and older, participated in an obesity management program for four weeks. They were divided randomly into two groups: a control group (n = 25) and a treatment group (n = 25). The treatment group was provided an application for nutrition management and diet consultant, while the control group maintained their ordinary life without any nutrition management. Results: The weight of the treatment group decreased by 0.8 kg, but the change was not significant. In contrast, the waist-hip ratio of the treatment group decreased significantly from 0.75 to 0.71 (p = 0.012). The Nutrition Quotients of the treatment group increased significantly from 61.3 to 69.6 points (p < 0.001), whereas that of the control group decreased significantly from 61.5 to 59.0 (p = 0.002). Conclusion: This mobile nutrition management application for breast cancer patients is effective in managing obesity and dietary habits. These results can be used as basic information to prepare an obesity management program for breast cancer patients.
Patients undergoing peritoneal dialysis are at risk for protein-energy malnutrition because of nutrient losses during dialysis. This study determined the nutritional status of patients undergoing continuous ambulatory peritoneal dialysis (CAPD). Forty-four patients receiving CAPD were divided into two groups according to dialysis period. We investigated the nutritional status of the patients by measuring anthropometric and biochemical parameters, as well as food intake, self-appetite, dietary habits, a subjective global assessment, and a total nutritional status assessment. Group I subjects (7 males, 13 females) had received dialysis for < 2 years, whereas the group II subjects (18 males, 6 females) received dialysis for ${\geq}$ 2 years. Energy intake with added dextrose in the dialysate per kg of body weight was $30.3{\pm}5.8$ kcal in group I and $29.0{\pm}8.1$ kcal in group II. The average protein intake per kg of weight was $1.0{\pm}0.3$ g in group I and $1.0{\pm}0.4$ g in group II, which were less than the recommended protein intake for patients undergoing CAPD (1.2-1.5 g/kg). Mean serum albumin level was significantly lower in group II than that in group I (p < 0.05). A recent self-appetite score was significantly higher in group II than that in group I (p < 0.01). The dietary habits score was significantly lower in group II than that in group I (p < 0.05). The subjective global assessment was significantly higher in group I (85.0%) than that in group II (54.2%) under normal nutrition status (p < 0.05). The dialysis period was significantly and negatively correlated with the subjective global assessment (r = -0.502, p < 0.01) and the total nutritional status assessment (r = -0.575, p < 0.01). These results demonstrated that patients undergoing CAPD for ${\geq}$ 2 years had worse nutritional status than those who had been undergoing dialysis for < 2 years. Good nutritional status can predict the long-term survival of patients undergoing peritoneal dialysis. Additionally, the exact evaluation of nutritional status before 2 years will be important to maintain long-term dialysis therapy in patients undergoing CAPD.

Pancreatic lipase is a potential therapeutic target for the treatment of diet-induced obesity in humans. As part of our continuing search for novel bioactive compounds, the convenient enzymatic transformation of caffeic acid into neolignans as well as related oxidized-products enhanced pancreatic lipase inhibitory activity. Enzymatic transformation of caffeic acid (1) using polyphenol oxidase originating from Korean pear yielded four oxidized metabolites, which were identified by different spectroscopic techniques ($^1H$,$^{13}C$ NMR, DEP/T, $^1H-^1H$ COSY, HMBC, HMQC, and NOESY). The anti-obesity efficacy of caffeic acid reactant was tested by in vitro porcine pancreatic lipase assay. All tested samples showed dose-dependent pancreatic lipase inhibitory activities. Four oxidative products including phellinsin A (2), caffeicinic acid (3), isocaffeicinic acid (4), and 7,8-erythro-caffeicin (5) were isolated and identified. The major metabolites (2~5) were evaluated for their pancreatic lipase inhibitory activity, and oxidized-products (2~3) improved potency against pancreatic lipase when compared to original caffeic acid. This result suggested that the neolignans isolated from oxidative transformation of caffeic acid might be beneficial in the treatment of obesity and relevant diseases, and the convenient enzymatic transformation by polyphenol oxidase may be a valuable method for structural modification and enhancement of activity.
