Cardiovascular diseases (CVDs) are the most common cause of death in patients with nonalcoholic fatty liver disease (NAFLD) and dyslipidemia is considered at least partially responsible for the increased CVD risk in NAFLD patients. The aim of the present study is to understand how hepatic de novo lipogenesis influences hepatic cholesterol content as well as its effects on the plasma lipid levels. Hepatic lipogenesis was induced in mice by feeding a fat-free/high-sucrose (FF/HS) diet and the metabolic pathways associated with cholesterol were then analyzed. Both liver triglyceride and cholesterol contents were significantly increased in mice fed an FF/HS diet. Activation of fatty acid synthesis driven by the activation of sterol regulatory element binding protein (SREBP)-1c resulted in the increased liver triglycerides. The augmented cholesterol content in the liver could not be explained by an increased cholesterol synthesis, which was decreased by the FF/HS diet. HMG-CoA reductase protein level was decreased in mice fed an FF/HS diet. We found that the liver retained more cholesterol through a reduced excretion of bile acids, a reduced fecal cholesterol excretion, and an increased cholesterol uptake from plasma lipoproteins. Very low-density lipoproteintriglyceride and -cholesterol secretion were increased in mice fed an FF/HS diet, which led to hypertriglyceridemia and hypercholesterolemia in Ldlr-/- mice, a model that exhibits a more human like lipoprotein profile. These findings suggest that dietary cholesterol intake and cholesterol synthesis rates cannot only explain the hypercholesterolemia associated with NAFLD, and that the control of fatty acid synthesis should be considered for the management of dyslipidemia.

Although fasting programs have recently attracted close attention because of benefits of detoxification, few studies have examined these programs. This study investigates the effects of a modified juice-based fasting program on lipid metabolism. A total of 33 volunteers fasted for 10 days and participated in program lectures, exercise programs, water bath regimens, and enemas. Pre- and post-program blood samples were obtained to evaluate lipoprotein levels. A paired t-test was conducted using SPSS 18.0. Changes in the lipid profile were observed during the juice-based fasting program and attending 3 degrees. All lipid profiles decreased significantly, including total cholesterol (TC) (p<0.001), triglycerides (TG), high-density lipoprotein cholesterol (HDL-C), and low-density lipoprotein cholesterol (LDL-C) (p<0.05). Program participation was documented by assessing attendance levels as high, moderate, and low. TC decreased significantly in all programs and levels (p<0.05), TG decreased proportionally only in enemas according to the attending degree: high (48 %), moderate (20 %), and low (10 %). HDL-C decreased at all low levels, but moderate exercise ($53.8{\pm}12.5mg/dL$ to $55.6{\pm}10.2mg/dL$) and a high enema ($54.9{\pm}14.1mg/dL$ to $55.0{\pm}9.4mg/dL$) showed small increases. The antioxidant property of the juice-based fasting program in terms of the blood vessel, enemas, and exercise played an important role in preventing cardiovascular disease from increased levels of HDL-C. These results suggest that juice-based fasting and combined lifestyle programs may help improve lipid metabolism and protect against dyslipidemia.

Male mice (ddY strain) were fed a laboratory chow diet containing 10% sucrose supplemented with orotic acid, hesperetin or naringenin at the 1% level for 14 days. the concentrations of liver triacylglycerol and cholesterol were significantly lower in the OA group than in the control group. When both flavonoids and orotic acid were administered simultaneously, the orotic acid-dependent decrease in liver triacylglycerol and cholesterol were attenuated slightly. The concentration of serum cholesterol in the orotic acid group or the control group was lower than in the orotic acid groups supplemented with hesperetin or naringenin. There were no significantly difference in body weight gain, diary food intake, and the serum concentrations of triacylglycerol and high-density-lipoprotein cholestrol. It was concluded that the inducement of fatty liver in mice failed to feeding a laboratory chow diet containing 10% sucrose supplemented with 1% orotic acid for 14 days.

The benefits of milk on the rats supplemented with cholesterol and vitamin D2 in diet was investigated. A total of 150 male rats of Sprague-Dawley strain, 5 weeks of age, were divided into 6 groups with the diet. Cholesterol control group was fed the diet containing 1.0% choleterol and 50,000 IU/100 g of vitamin D2 for 24 months, and M0.5, M1, M2 and M5 of milk groups were fed the diet containing cholesterol, vitamin D2 and 0.5, 1, 2 and 5 of reference daily intakes of whole milk, respectively. No remarkable differences of growth, diet intake, and food effciency ratio among groups were observed though rats in cholesterol control group showed abrupt decrease of diet intake and body weight showed slightly higher relative organ weights than did the rats in control group. The rats in cholesterol control group showed the highest serum total cholesterol level. The rats in milk groups showed lower total cholesterol level and higher high density lipoprotein (HDL)-cholesterol fraction than did the rats in cholesterol control group though no tendency was observed among milk groups. In milk groups, aorta, heart, kidney and liver of rats showed milder calcification and necrosis or fat degeneration compared with those in cholesterol control group. The above results suggest that whole milk could have beneficial effect on the cholesterol-and -vitamin D2-induced atherosclerosis in rats.

Purpose: The triglyceride-to-high-density lipoprotein-cholesterol (TG/HDL-C) ratio is one of the main predictive indices for cardiovascular disease. This study was examined the relationship between TG/HDL-C ratio and metabolic syndrome (MetS) in male office workers. Methods: Secondary analysis was conducted to determine the risk between the TG/HDL-C ratio and MetS in male office workers. A total of 765 people underwent the 'regular workplace health checkups in 2014'. Among the subjects who were male and responded to the questionnaire and health lifestyle survey, 470 (61.4%) excluding those with missing and/or abnormal values were analyzed. The association between MetS, MetS components, and the TG/HDL-C ratio was examined by a Chi-square test, One-way ANOVA, Turkey post-hoc test and Logistic regression analysis. Results: The number of males with MetS was 70 (14.9%) and the number of MetS components increased with increasing TG/HDL-C ratio (p<.001). Logistic regression analysis with an adjustment for potential confounders revealed a 31.8 times higher odds ratio of the Quartile4 group for MetS than that of the Quartile1 group (p<.001). Conclusion: These results show that the likelihood of MetS, particularly the risk of MetS in the Quartile4, increases with increasing TG/HDL-C ratio.

Clinical-chemical traits are commonly used biomarkers to examine the health status of individuals. There is an appreciable range of normal variation in most clinical-chemical traits and the determining factors of this variation have been relatively uninvestigated in chickens. The aim of this study was to estimate the genetic parameters (i.e., heritability, genetic correlation) for 8 clinical-chemical traits (glucose, total protein, creatinine, high-density lipoprotein cholesterol, total cholesterol, glutamic oxaloacetic transaminase, glutamic pyruvic transaminase and amylase) in an $F_1$ intercross established by purebred breeding among the 5 lines of Korean native chickens. Phenotypic data were collected from approximately 600 $F_1$ animals. The genetic parameters for the clinical-chemical traits estimated by a mixed animal model using the restricted maximum likelihood method were presented. Estimated heritabilities ranged from 8.9% (glucose) to 39.6% (high-density lipoprotein cholesterol). Interestingly, both the sign and the size of the genetic and phenotypic correlations were largely different between the same several pair of clinical-chemical traits. The findings in this study will provide useful information to address issues in both quantitative trait locus study and genetic management in Korean native chickens.
