Low-fat, precooked high quality Wanjajun was prepared by treating natural antioxidant herbs and hydrocolloids for quantity production of cook/chill system in foodservice. The proposed Wanjajun was formulated under the consideration of flavor and fat level. Wanjajun was prepared with hydrocolloid such as sodium alginate, car-boxymethyl cellulose (CMC), carrageenan and xanthan gum. Cooking yield, fat retention and water holding capacity of Wanjajun containing hydrocolloidal gums were higher than those of control. L-value of raw product was low in comparison with cooked product, but a-value was higher than that of other cooked product. Colors of raw and cooked products were not different among five kinds of products. pH value of cooked product was higher than that of raw product pH range of cooked products revealed to 6.10~6.23. There was no considerable change in pH value during storage. The coliform group and Staphylococus aureus were not detected during storage. Total bacteria1 counts were close to microbial guidelines for safe condition. Hardness, springness, cohesiveness, gumminess and brittleness of low-fat products were generally lower than those of control product. Hardness, gumminess and brittleness of reheated products were higher than those of preheated products. Flavor, tenderness, juiciness and overall quality were not different between precooked and reheated products. Textural characteristics of products were superior in the order of sodium alginate, xanthan gum, CMC, carrageenan and control product.

The effects of genistein on cell proliferation and adipogenesis were examined in mouse 3T3-L1 preadipocyte cells. Genistein decreased viability of 3T3-L1 pre-adipocytes in a dose-dependent manner. Oil Red O staining of these cells also indicated that adipogenesis was inhibited by 50 ${\mu}M$ genistein treatment. We investigated the molecular mechanisms involved in the decrease in cell viability in genistein-treated 3T3-L1 cells by conducting an oligo DNA microarray analysis. We selected the sirtuin-1 gene, one of the upregulated genes, for further experimentation because sirtuin-1 belongs to the sirtuin family, which is associated with anti-obesity and anti-inflammation activities. We found that four phytochemicals (resveratrol, capsaicin, daidzein, and genistein) could increase sirtuin-1 expression. Genistein was the strongest inducer of sirtuin-1 among the tested phytochemicals. The inhibition of adipogenesis by genistein was recovered by surtuin-1 siRNA transfection. Overall, these results may further our understanding of the molecular mechanisms underlying the inhibition of proliferation and adipogenesis by genistein in mouse 3T3-L1 cells.

White adipose tissue is now recognized as an important endocrine organ which secretes various signal factors and proteins termed 'adipokine'. Haptoglobin (Hp), which has been known as an acute phase protein, belongs to the adipokine. However, the function of Hp in adipose tissue remains unclear. To verify the role of Hp in preadipocytes, in this study, 3T3-L1 preadipocyte cells were stably transfected with human Hp gene and Hp-overexpressing cells were made. The Hp had no effect on cell growth of preadipocytes. By RT-PCR and Western blot analysis, the Hp inhibited gene expression of IL-6 and COX-2 and enhanced HO-1 synthesis in preadipocytes. Moreover, invasion assay showed the Hp suppressed migration of monocytes to preadipocytes. These findings suggest that the Hp may inhibit an inflammatory reaction in adipose tissue by regulating the expressions of pro-inflammatory and anti-inflammatory mediators, and by repressing monocytes/macrophages infiltration.

Short-chain acyl-CoA dehydrogenase (SCAD) deficiency is a rare mitochondrial fatty-acid oxidation disorder that is inherited as an autosomal recessive pattern. SCAD deficiency is caused by mutations in the ACADS gene (Acyl-CoA Dehydrogenase, Short-chain, OMIM #606885), which encodes SCAD, the mitochondrial enzyme that catalyzes the first reaction in the beta-oxidation of fatty acids four to six carbons in length. Here, we describe one Korean pediatric case of SCAD deficiency, which was diagnosed during newborn screening through tandem mass spectrometry. An increased concentration of butyrylcarnitine was detected on the newborn screening test, and the urine organic acid analysis showed increased urinary excretion of ethylmalonic acid. The patient has been asymptomatic and has shown normal growth and development by 8 months of age without any intervention during follow-up period.

Transcatheter arterial chemoembolization(TACE) was performed in a 61 year old male patient with hepatocellular carcinoma with 10 cc of Lipiodol and 50 mg of doxorubicin. Three days later, he complained of dyspnea and dry cough. The arterial blood gas study revealed moderate hypoxemia and hypocarbia. The chest PA showed acute pulmonary edema with bilateral pleural effusion. To rule out the possibilities of acute respiratory failure caused by infection, pulmonary embolism or congestive heart failure, we performed several laboratory studies. The blood and sputum culture studies revealed negative results for bacterial growth. The echocardiogram was normal. The abdominal CT scan and MR imaging revealed no thrombus or mass lesion in the inferior vena cava. So we concluded pulmonary oil embolism induced by lipiodol as the cause of acute lung injury. Four weeks later, clinical symptoms and chest x-ray were markedly improved with conservative care. We report a case of acute lung injury after TACE with lipiodol and doxorubicin, with review of literatures.

Background: Although aortic valve sclerosis causes no significant hemodynamic alterations, it is associated with an increased risk of cardiovascular death and myocardial infarction. However, the role of ${\beta}_3$ integrin in aortic valve sclerosis remains unclear. Material and Method: Twenty male New Zealand rabbits were divided into two groups. Group 1 rabbits (n=10) received a normal chow diet, while group 2 (n=10) rabbits received a diet containing 1% cholesterol for 12 weeks. After the rabbits were euthanized, their aortic valves and ascending aortas were excised for analysis. Result: Total serum cholesterol ($2,148.3{\pm}1,012.5\;mg/dL$ versus $53.7{\pm}31.8\;mg/dL$, p<0.05), triglyceride ($240.4{\pm}218.3\;mg/dL$ versus $31.6{\pm}6.4\;mg/dL$, p<0.05), and low density lipoprotein (LDL)-cholesterol($2,065.3{\pm}960.9\;mg/dL$ versus $29.1{\pm}30.9\;mg/dL$, p<0.05) levels were significantly higher in the cholesterol diet group compared with the normal diet group. Myofibroblasts and macrophages were more highly expressed in the aortic valve leaflets of rabbits in the cholesterol diet group than of those in the normal diet group. A real-time polymerase chain reaction revealed decreased ${\beta}_3$ integrin mRNA levels in the hypercholesterolemic aortic valves and aortas. Conclusion: The present study shows that hypercholesterolemia induces aortic valve sclerosis. These findings suggest that alterations in ${\beta}_3$ integrin may playa role in the development of aortic valve sclerosis.

Objectives : The purpose of this study is to evaluate the anti-lipogenic effect of Sobuncheong-eum on non-alcoholic fatty liver disease in free fatty acid induced cellular model. Methods : HepG2 cells were treated with palmitate for 24h to overload intracellular triglyceride (TG) content in the presence or absence of Sobuncheong-eum extract. After palmitate treatment, Intracellular TG content was measured with TG assay kit. Several lipogenesis related markers, including AMP-activated protein kinase (AMPK), sterol regulatory element-binding transcription factor-1c (SREBP-1c), acetyl-CoA carboxylase (ACC), and fatty acid synthase (FAS), were assessed using Western-blot analyses and RT-PCR. Results : Palmitate markedly increased intracellular TG in HepG2 cells, and which were alleviated by coadministered Sobuncheong-eum extract. Sobuncheong-eum extract activated AMPK, which plays a key role in reducing hepatic lipid accumulation, and reduced lipogenic fators, SREBP-1c, ACC, and FAS. Conclusions : Taken together, it is conceivable that Sobuncheong-eum has an potential to alleviate steatosis, and which may be mediated by activating AMPK at least in part.

Magnolia extract, prepared from the Chinese herb Magnolia officinalis, is known for its potent anti-oxidative and anti-inflammatory effects. In this report, we showed that Magnolia extract inhibits adipocyte differentiation, as evidenced by reduced triglyceride (TG) accumulation. Also, Magnolia extract increased hormone sensitive lipase (HSL) protein level, and decreased the adipogenic transcription factor peroxisome proliferator activated receptor (PPAR)-${\gamma}$ protein and their corresponding mRNA. Our results suggest a potential apllication of Magnolia extract as anti-obesity agents inhibits adipocyte differentiation through the down-regulation of adipogenic transcription factors and other adipocyte-specific genes.

In the period of rapid economic growth, it is possible to practice the growth policy by factors input and the regional development policy by the dispersion of growth. But, in the period of weakened growth, this model loses its theoretical and practical merit. The endogenous regional development model that can efficiently cope with a international competition and a uncertainty of international economy become an alternative policy of growth and regional development. France, which had a problem of overcrowding in the capital region by the centralized growth policy and regional development policy, phase the regional innovation system policy in order to establish the foundation of an endogenous regional development from the 1970's. The regional innovation system policy in France which pursues simultaneously the systematic regional knowledge creation and the regional development is very suggestive to the regional innovation system policy in Korea that pursues the endogenous regional development and the solution of the regional disparity.

Purpose: The purpose of the study was to investigate whether adherence to the Korea Healthy Eating Index (KHEI) was associated with metabolic syndrome and risk markers. Methods: The participants included 8,345 adults, aged 20-59 years, who took part in the 7th Korea National Health and Nutrition Examination Survey (KNHANES). The data were analyzed using a complex-sample t-test, the Rao Scott χ²-test, and logistic regression analysis on the SPSS v. 26.0 software. The participants were divided into four groups by quartiles of KHEI scores. Results: The average KHEI score was 61.06 points out of 100, and the women's score (62.50 points) was significantly higher than that of men (59.63 points). The KHEI quartiles status showed significant differences by age (p < 0.001), household income (p < 0.001), smoking status (p < 0.001), and food security. Specifically, the KHEI quartiles in the men showed significant differences in education (p < 0.001) and economic activity (p < 0.001) whereas those of women showed significant differences in alcohol-consumption (p < 0.001), depression (p < 0.01) and eating-out (p < 0.001). As the KHEI scores increased, the proportion of subjects with an energy intake below the estimated energy requirement (EER) was lower, and significantly better levels of intake were observed for carbohydrate, protein, vitamin C, calcium, vitamin B₁, vitamin B₂, and niacin. The incidence of the metabolic syndrome risk factors, hypertriglyceridemia and hyperglycemia for men and hypertension, and hyperglycemia for women showed significant differences. The KHEI scores were inversely associated with abdominal obesity, hypertriglyceridemia, low high-density lipoprotein cholesterol, hyperglycemia, hypertension, and metabolic syndrome. Conclusion: Based on these results, we conclude that higher adherence to the KHEI was associated with lower metabolic syndrome risk factors and incidence of the metabolic syndrome.
