The purpose of this study was to determine the health behaviors and nutritional status related to dyslipidemia in Korean middle-aged adults (between 50 and 64 years old) from the Korean National Health and Nutrition Examinations Survey data (2007~2010). A total of 4,721 subjects were analyzed in this study. The subjects were divided into three groups (normal, borderline, and dyslipidemia) according to serum lipid levels. Parameters included in this study were drinking and smoking, anthropometric parameters, blood and nutritional parameters. The latter parameter included food/nutrients intake. All data was adjusted by sex, region, education level, and age. General linear model and logistic regression model were used for statistical analysis. The dyslipidemia group was comprised of more men than women. By contrast, the borderline group was comprised of more women than men (p<0.001). No significant differences were observed for other general characteristics. There were more smokers and drinkers(drinking per time) in the dyslipidemia group (p<0.05). Anthropometric data showed significant difference, ie, height (p<0.05), weight, body mass index, waist circumference, percent body fat, and blood pressure were higher in the dyslipidemia group (p<0.001). Only blood urea nitrogen showed no significant difference among groups. The HbA1c (p<0.01), fasting blood glucose, GOT, GPT, creatinine levels were higher in the dyslipidemia group (p<0.001). So it is required for the management of obesity in dyslipidemia group. The dyslipidemia group ate less sea food (p<0.05). The nutrients intake of energy and protein, thiamin, riboflavin, niacin, calcium, phosphorus were lower in the dyslipidemia group (p<0.05). Therefore, to lower dyslipidemia prevalence rates, it is necessary to increase the intake of foods containing ω-3 fatty acids. We also suggest a meal management program and nutritional education to recognize the risk of dyslipidemia, especially for people such as the individual in the borderline and dyslipidemia study groups. Key words: dyslipidemia, Korean middle-aged adults, nutritional status, health behaviors

The purpose of this study was to discuss how ‘milk’ was produced and supplied introduced and spread in the modern Joseon period. Condensed milk and powdered milk were mainly consumed in Joseon during the Japanese colonial period since they could be conveniently preserved for a long time, although raw milk was also produced and consumed. For areas adjacent to farms, milk delivery service was offered while areas with great consumption received an additional supply from different areas by rail. Since no manufacturing plants were operational in Korea, condensed milk and powdered milk consumed in Joseon had to be imported. In the case of condensed milk, when production in Japan increased, extra supply was aggressively sent into their colony, Joseon. The ‘Gyeongseong Milk Association’ founded in 1937 is considered significant in that it led to standardization of the production system and prices as well as pasteurization of milk. In the late Japanese colonial era, milk production and consumption were controlled. As milk was purchased as a war supply, the milk consumption market became distorted and limited

Somatic cell nuclear transfer (SCNT) technique is a key point of producing transgenic animal disease models. During in vitro production of SCNT embryo, the quality of matured oocytes are one of the important factors that regulate embryo developmental capacity. In preliminary test, we confirmed the effect of fibroblast growth factor 10 (FGF10) on porcine oocyte maturation. In this study, we investigated the developmental potential of SCNT embryos treated with the 10 ng/ml FGF10 (10 F) during in vitro maturation of recipient oocytes. The polar body emission rate was significantly higher in the 10 F treated group than control group. After SCNT, although the rate of fusion was no significant difference, the rate of cleavage and blastocyst formation was significantly increased in the 10 F treated group (p<0.05). In 10 F treated group, the total cell number was increased and the percentage of apoptotic cell was decreased in the blastocyst stage at day 7 (p<0.1). The transcription level of apoptosis relative gene, Casp3 was significantly decreased, while anti-apoptosis gene BCL2l1 was increased in the 10 F treated group compared to control group. The 10 F treated group was highly expressed the reprogramming related genes, Sox2 and POU5f1. Also, the first cleaving time was more faster and the percentage of cell block was significantly lower in 10 F treated group than in control group. In this study, we confirmed that 10 ng/ml FGF10 has effect on enhance the oocyte maturation and developmental capacity. These results demonstrate that FGF10 treatment can be used for in vitro development of porcine SCNT embryos and subsequent production of transgenic animal model.

Kisspeptin-10 (KP-10) has been reported to act as a tumor metastasis suppressor via its receptor, G protein-coupled receptor 54 (GRP54). The KP-10/GPR54/BMPs signaling pathway plays an important role in embryonic kidney development. However, its function in osteoblast differentiation is unknown. The aim of this study was to confirm the molecular mechanism for the action of KP-10 on osteoblast differentiation. Expression of the Bone morphogenetic protein-2 (BMP2) and osteogenic genes were determined by RT-PCR and real-time PCR analysis in C3H10T1/2 cells. Transient transfection assays were performed to confirm the effects of KP-10 on BMP2-Luc activity. BMP2 and phospho-Smad1/5/9 protein levels were determined by Western blot analysis. Alkaline phosphatase (ALP) staining experiment was performed to evaluate ALP activity. To further confirm the effect of KP-10-induced GPR54, we used GPR54 Knock out (KO) C3H10T1/2 cells. KP-10 significantly increased osteogenic gene such as Runx2, ALP and Dlx5 in C3H10T1/2 cells. The ALP staining levels were also increased by KP-10. Interestingly, BMP2 mRNA, protein expression and promoter activity were also increased by KP-10. However, KP-10-induced BMP2 expressions were not increased in GPR54 KO cells. These results suggest that KP-10 increases BMP2 expression through GPR54. Next, Western blot analysis shown Smad1/5/9 phosphorylation were enhanced in a time-dependent manner by KP-10 treatment. It is well known that BMP2 increased phosphorylation of Smad1/5/9 via BMP2 receptor. In addition, KP-10 increased NFATc4 mRNA levels and NFATc4 overexpression enhance BMP2 mRNA levels. To confirm the KP-10-induced BMP2 action, we used KP-10-treated medium in wild type cells and GPR54 KO cells. The osteogenic genes were not elevated by KP-10-treated medium (GPR54 KO cells) whereas increased expression levels by KP-10 medium (wild type cells). These data indicate that KP-10 induced osteoblast differentiation through NFATc4-mediated BMP2 signaling.

S100As are calcium-binding proteins with two EF-hand calcium-binding motifs. In several studies, S100A proteins are described to play important roles in pro-inflammatory responses including damage-associated molecular pattern (DAMP) signaling and in the establishment of pregnancy. However, the role of S100As have not been determined in the uterine endometrium during the estrous cycle in pigs. Thus, this study was performed to investigate expression and regulation of S100A8, S100A9, and S100A12 in the uterine endometrial tissues during the estrous cycle in pigs. Real-time RT-PCR analysis showed that S100A8, S100A9, and S100A12 mRNAs were expressed in the uterine endometrium during the estrous cycle with higher levels on days 15 and 18 of the estrous cycle than other days of cycle. To investigate the effects of steroid hormones, estradiol (E2) and progesterone (P4), on expression of S100A8, S100A9, and S100A12 mRNAs, endometrial tissue explants from immature pigs were treated with steroid hormones. Levels of S100A8, S100A9, and S100A12 were increased by the treatment of P4, and the increased levels of S100A8, S100A9, and S100A12 by P4 were not inhibited by the treatment of progesterone receptor antagonist, RU486. However, levels of S100A8, S100A9, and S100A12 were decreased by treatment of MEK inhibitor, U0126. These results exhibited that S100As were expressed in the uterine endometrium during the estrous cycle in a cyclic stage-specific manner, and their expression was affected by P4. These suggest that S100As may play an important role in endometrial function during the proestrous period of the estrous cycle in pigs.

Cytokines may play an important role in the acute rejection (AR) of solid organ transplantation. Many studies have investigated the association between interleukin-10 gene (IL-10) polymorphisms and risk of AR. The aim of this study was to determine the relationship between IL-10 polymorphism (-1082, G/A) and AR risk after solid organ transplantation in Caucasian population. A comprehensive electronic search of PUBMED, Google Scholar, and Korean databases was performed. Meta-analysis was performed using comprehensive meta-analysis software (Biostat, NJ,USA). We assessed the pooled p-value, odds ratio (OR), and 95% confidence interval (CI) to measure the association between the risk of AR and IL-10 polymorphism (-1082, G/A). The OR and 95% CI were used to evaluate the strength of the association. P-values less than 0.05 were considered statistically significant. Fourteen case-control studies were included in this meta-analysis. In overall analysis, we observed that IL-10 polymorphism (-1082, G/A) was associated with the AR in liver transplantation (G allele vs. A allele, OR = 1.436, 95% CI = 1.006-2.050, p = 0.046 in fixed model). However, IL-10 polymorphism (-1082, G/A) did not show any significant association with solid organ transplantation and renal transplantation (p>0.05 in each model, respectively). Our meta-analysis suggests that IL-10 polymorphism (-1082, G/A) may be related to susceptibility of AR in liver transplantation recipients.

이 연구에서는 2014년 6월 10일 일산에서 발생한 용오름에 대해 구름분해모델(CReSS)를 활용하여 재현실험을 수행하고 발생 메커니즘을 분석하였다. 종관적으로는 대기 상층의 한랭하고 건조한 공기가 남하하였으며, 대기 하층에서는 온난하고 습윤한 공기의 이류가 있었다. 이로 인해 대기 상 하층 기온의 큰 차이가 발생하면서 강한 대기 불안정을 야기 시켰다. 19시 20분에 일산 지역에서 스톰이 발달하기 시작하여 10분 만에 최성기에 도달하였다. 재현 실험 결과 이 때 발달한 스톰의 높이는 9 km이었으며, 스톰 후면으로 갈고리 에코(hook echo)가 나타났다. 일산 주변으로 발달 한 스톰 내부에서는 활강 기류가 발생하는 것으로 모의 되었다. 모의된 하강기류가 지면에서 발산되어 수평 흐름으로 변하게 되었고, 이 흐름은 스톰의 후면에서 상승류로 전환 되었다. 이 때 후면에서 강한 하강기류가 발생하였는데 이 하강류가 전환된 상승류를 지면까지 끌어내려 지면에서 소용돌이도가 발달하게 되었다. 그 이후 이 소용돌이도가 연직으로 신장되면서 용오름이 모의되었다. 모의된 용오름에서 발달한 저기압성 소용돌이도는 360 m 고도에서 3×10−2 s−1이 었으며, 용오름의 직경은 900 m 고도에서 1 km로 추정되었다.

The purpose of this study was to evaluate the nutrient intake, diversity and prevalence of diseases according to noodle consumption using data from the Korean National Health and Nutrition Examination Survey (KNHANES) of 2010. Korean adults (>20) were classified into two groups, noodle group (NG) and non-noodle group (NNG). NG was found to have higher intakes of protein, calcium, iron, sodium, potassium, and niacin. The DVS and DDS according to noodle consumption were found to be 21.76 and 3.51 for NG, and 18.56 and 3.40 for NNG, this result was thought to show that the diet of NG was more satisfactory than that of NNG in terms of dietary diversity. In the bone mass of entire subjects, NG showed higher figures in the femoral neck and lumbar spine than NNG. For bone mineral density, NG exhibited higher figures in the femoral neck, and for T-scores, the values of NG was significantly higher in the femoral neck than those of NNG. However, the prevalence of osteoporosis of NG and NNG was 11.6% and 9.5%. The prevalence of osteopenia of NG and NNG was 43.0% and 51.7%. Thus, these results showed that overall bone health of NG was better than that of NNG. Dietary balance and quality were also more satisfactory in NG. These results showed that noodle consumption may have an impact on the prevalence of chronic diseases.
