We investigated the effect of high density lipoprotein from egg yolk (EYHDL) on serum, hepatic and fecal lipid and fatty acids (FAs) levels and on gene expression involved in FAs metabolism. Male KM mice were fed either normal diet (ND; n=20), high fat diet (HFD; n=20), or high fat diet containing EYHDL (EYHDL; 0.6 mg/g, every day by oral gavage, n=20) for 100 days. At the end of the experiment, the effects of treatments on biochemical parameters, FAs profiles and involved gene expression were analyzed. Our results revealed that EYHDL markedly suppressed the body weight gain, accumulation of abdominal fat tissues, serum concentrations of LDL-cholesterol (LDL-C) and triglycerides, hepatic triglycerides and cholesterol accumulation, while increased serum concentration of HDL-cholesterol (HDL-C). EYHDL intake also increased total cholesterol (TC) excretions compared with HFD group. Moreover, it alleviated the severity of fatty liver and improved glucose and insulin tolerance compared with HFD. More importantly, EYHDL partially normalized FAs profiles in serum, liver and fecaces and neutralized the HFD-induced upregulation of SREBP-1c, Acaca, Fasn, GPAT and Scd1. In conclusion, our findings indicate that EYHDL may have the potential to improve metabolic disturbances that occur in HFD mice and can be considered as an appropriate dietary recommendation for the treatment of metabolic syndrome (MetS).

Objective: This study was conducted to evaluate the effects of optimal trace mineral levels on the physiological responses, reproductive performance, litter performance, blood profiles and milk composition in gestating sows. Methods: A total of 59 multiparous sows (Yorkshire×Landrace) with similar body weight (BW), backfat thickness (BF), and parity were assigned to one of four treatments with 14 or 15 sows per treatment using a completely randomized design. The treatments were 100% (M1), 300% (M3), 600% (M6), and 900% (M9) of the National Research Council (NRC) Nutrient Requirements of Swine. During lactation period, all the sows were fed the same commercial lactation diet. Results: No significant differences were observed in the BW, BF, reproductive performance, milk composition, or growth performance of the piglets. On day 70 of gestation, the serum zinc concentration showed a quadratic response to M6 treatment (quadratic, p<0.05). Moreover, as the dietary mineral levels increased, the zinc concentration increased linearly at 110 days of gestation (linear, p<0.05). Furthermore, copper and iron concentrations in the serum of sows at 24 h postpartum decreased linearly when high levels of dietary minerals were provided (linear, p<0.05). In the serum of piglets, serum zinc concentrations decreased linearly (linear, p<0.05), and iron concentration showed a quadratic response (quadratic, p<0.05) with an increase in trace mineral premix levels in gestation diets. Conclusion: The current trace mineral requirements of NRC (2012) are suitable for gestating sows, and the addition of dietary mineral levels in the gestating diet did not show any improvements during the gestation and lactation periods.

As a result of a nutrition transition, chronic diseases, including diabetes, have increased in Iran. Nutrition education is a cost-effective method for modifying diet and controlling diabetes. This study aimed to examine the effect of nutrition education using MyPlate recommendations on glycemic and lipid profiles and inflammatory markers in Iranian adults diagnosed with type 2 diabetes. A 12-week randomized clinical trial was conducted on 44 adults aged 30-50 years from Ahvaz, Iran. The participants were divided into education and control groups. The education participants were taught the MyPlate recommendations. Serum levels of fasting blood sugar (FBS), hemoglobin A1c (HbA1c), lipid profiles, and inflammatory markers, including high sensitivity C-reactive protein (hs-CRP), tumor necrosis factor-α, and adiponectin, were measured at the baseline and the end of the study. The results showed that serum levels of FBS (p = 0.014) and HbA1c (p < 0.001) decreased significantly in the education group at the end of the study. The serum level of low-density lipoprotein in the education group declined significantly at the end of the study (p = 0.043). Furthermore, the serum level of hs-CRP (p = 0.005) declined significantly while the level of adiponectin (p = 0.035) increased in the education group at the end of the study. The evidence of this study showed that nutrition education using MyPlate recommendations is an effective method for controlling diabetes complications. A longitudinal analysis with a larger sample size is recommended to confirm the evidence of this study.

This study was performed to investigate the effects of genistein, a kind of soy isoflavones, on fatty liver and lipid metabolism in rats fed high fat diet. Twenty four male Sprague-Dawley rats were divided into four groups by dietary fat and genistein contents then raised for six weeks. The rats(n=6/group) were fed normal fat diet(NOR), high fat diet (HF), high fat with 0.1% genistein(HF+0.1%G) or high fat with 0.2% genistein(HF+0.2%G). Hepatic total lipid, triglyceride, total cholesterol and Serum GPT, as a marker for fatty liver, were significantly increased by high fat diet. Also, serum total lipid, triglyceride, total cholesterol, glucose and insulin concentration, hepatic lipogenic enzyme (fatty acid synthase and malic enzyme) activities were significantly increased by high fat diet. However, hepatic total lipid, triglyceride, total cholesterol and Serum GPT were significantly decreased by genistein intake. Also, genistein supplementation decreased serum total lipid, triglyceride, glucose and insulin concentration, hepatic lipogenic enzyme (fatty acid synthase and malic enzyme) activities. There were no differences by genistein level except for serum insulin. These results suggest that fatty liver induced by high fat diet was caused by increased serum lipid profiles and hepatic lipogenesis, whereas, genistein may be useful in inhibiting of fatty liver by reducing serum lipid profiles and hepatic lipogenesis.

The present study was conducted to determine the effects of L-carnosine (LC) and/or alpha-lipoic acid (ALA) supplementation on growth performance, blood thyroid hormones and lipid profiles in finishing pigs. A total of 40 ($Landrace{\times}Yorkshire$) pigs with an initial body weight of $57.93{\pm}3.14kg$ were randomly allocated to 4 experimental diets using a $2{\times}2$ factorial arrangement with 2 LC supplemental levels (0 or 0.1%) and 2 ALA supplemental levels (0 or 0.03%) in basal diets. The results showed that pigs fed LC-supplemented diets increased final live weight, average daily gain, and average daily feed intake compared to those of pigs fed without LC-supplemented diets (p<0.05). Dietary supplementation with ALA did not affect the growth performance and carcass traits of pigs (p>0.05). Additionally, LC supplementation increased serum triiodothyronine, thyroxine levels, and ALA supplementation increased serum triiodothyronine levels (p<0.05). Serum total cholesterol and triglycerides levels were significantly decreased in LC and ALA supplemented groups, respectively (p<0.05). Moreover, serum low density lipoprotein cholesterol levels were lower in the ALA-supplemented groups than those of pigs fed without ALA-supplemented diets (p<0.05). However, no significant $LC{\times}ALA$ interaction effect on growth performance, blood thyroid hormones and lipid profiles was found. This study suggested that dietary supplementation of LC resulted in better growth performance compared to that of ALA supplementation. L-carnosine and/or ALA supplementation positively modified blood lipid profiles, which may have the potential to prevent cardiovascular diseases.

This study was performed to investigate the anthropometric data, serum profiles, and nutrient intakes of high school students who are living in Seoul. Anthropometric data showed that mean height and weight were 174.1 cm and 66.6 kg in 99 male and 161.4 cm and 54.0 kg in 116 female students. Mean BMl for male and female students were 21.9 and 22.3 kg/$m^2$, and subjects with BMI > 25 kg/$m^2$ were 14 and 7%, respectively. Total cholesterol, HDL- and LDL-cholesterol of subjects were 149.6$\pm 3.1,\; 46.4 \pm 1.3,\; 86.4 \pm 2.3$,/TEX> mg/dl for males and 169.2 $\pm 3.1,\;50.7 \pm 1.0,\; 100.9 \pm 2.7 mg/dl$ for females, respectively. Hemoglobin (Hb) and total iron binding capacity (TIBC) were 12.8 $\pm 0.1 g/dl, \;437.3 \pm 7.2\mug/dl\; in\; male\; and\; 11.9 \pm 0.1 g/dl,\; 439.4 \pm 5.7\mug/dl$ in female, respectively. Based on Hb classification, 45.6% of male and 45.0% of female students fell into anemic condition. Intakes of energy, Ca, Fe, Zn, riboflavin, and folate were below the Korean RDA. In particular Ca (male and female, respectively, 64.6 and 64.3% RDA) and Fe (male and female, respectively, 78.6 and 64.3% RDA) intakes were extremely low. Serum triglyceride was positively significantly correlated with weight (r =0.22), BMI (r =0.279), waist circumference (WC, r =0.235), triceps skin-fold thickness (TSF, r =0.197) and obesity index (OI, r =0.279). Hb concentration was positively correlated with height (r + 0.387), weight (r =0.349), BMI (r =0.191) and waistlhip ratio (WHR, r =0.380). As for the correlation between serum profiles and nutrient intakes, the Hb concentration was positively correlated with energy (r =0.163), protein (r =0.149), Na (r =0.153), vitamin A (r =0.165), thiamin (r =0.201) and niacin (r =0.192, p < 0.01). These result suggest that the prevalence of Ca and Fe deficiency of student is high and dietary guideline for prevent anemia in this age needs to contain the adequate intake of energy and its related vitamins.

A ten-year-old, male cat presented with recent loss of body weight, depression, vomiting, anorexia, polydipsia, and polyuria. General physical findings included depression, weakness, severe dehydration and a strong acetone odor on the breath. A complete blood count and serum biochemical profiles were leukocytosis, hyperglycemia (286 mg/dl), hypokalemia (2.6 mEq/L), hyponatremia, and high serum fructosamine (600 $\mu$mol/L). In blood gas analysis the cat had acidosis (pH 7.127, p$CO_2$26.7 mmHg). In urinalysis glycosuria and ketouria were appeared. On the basis of clinical signs, serum chemistry, blood gas analysis and urinalysis, diabetic ketoacidosis was diagnosed. Treatment included subcutaneous administration of protamine zinc insulin (0.75 U/head) and intravenous administration of 0.9% saline. Potassium phosphate and sodium bicarbonate was added to the fluids. Serum fructosamine for assessment of glycemic control was measured on occasion calls. On day 296, the patient improved clinically and did not experience any problems resulting from diabetic ketoacidosis.

This study was designed to investigate the effectiveness of ginseng intakes in modifying serum lipid profiles and plasma clotting factors. The participants in this study were 47 normal healthy volunteers(men 24, women 23) with an age range of 35-49 years and a mean age of 41 years residing in Taejon. Based on the diet intakes, subjects were classed into one of three groups : control, vegetarian, and ginseng consumed over 3-4 years. There was no significant difference in their physical characteristics. Dietary calorie intakes were not significantly different in subjects. The ratio of energy intake in the control and ginseng consumed group was 63-64% : 20-21% : 15-16%(Cho : Fat : Pro), but 70-73% : 13-14% :14-15%(Cho : Fat : Pro) in the vegetarians. The intakes of animal food in the vegetarian was significantly lower than the control and ginseng consumed group in men. The ratio of P/S(1.27) was the highest in the vegetarians. Venous blood samples were taken for serum lipid profiling, plasma clotting assay and platelet function. The concentration of serum triglyceride in the men ginseng group is significantly lower than those of the men control group. Serum lipid profiles values of the men ginseng group, such as total cholesterol and phospholipid were lower those of the men control group, but higher those of the men vegetarian group. the serum lipid profile in the women were not significant, but total cholesterol, triglyceride and LDL cholesterol levels in the ginseng groups were low. The concentration of HDL cholesterol was not significantly different. Platelet cell count and platelet aggregation were low in the ginseng groups. APTT(Activated Partial thromboplastin time) was significantly elongated in ginseng groups in the normal range. In seems that the major beneficial effects of ginseng intakes in especially men were on the blood concentrations of triglyceride, total cholesterol and elongation of plasma clotting time.

The aim of this study was to assess the effect of 6-week vegetable juice supplementation (360 ml/day) on serum lipid profiles and antioxidant activity in college women. Twenty women (mean age: 21) with normal life style and dietary pattern and who are free of any specific diseases were recruited among the student in S women's university. The subjects consumed vegetable juice to take part in an uncontrolled clinical trial for a 6-week intervention period. While there was no difference in the concentration of total cholesterol and HDL-cholesterol, serum concentrations of TG and HDL/LDL ratio were significantly reduced by $22\%$ (p = 0.013) and $6\%$ (p =0.007) respectively. Significant decrease in manlondialdehyde (p = 0.000) was accompanied by an increase in the activity of serum antioxidant enzymes, such as GSHPx (p = 0.000), SOD (p=0.007). It was also found that total antioxidant status was improved by $5.4\%$ (p=0.009). Serum parameters were all changed without affecting body mass index, waist and hip circumferences, or nutrient intakes after six week of supplementation. This study demonstrated that the supplementation regular meals with vegetable juice can favorably affect serum lipid profiles and antioxidant systems, and hence could contribute to reduce the risks of chronic diseases in college women.

This study investigated the effects of carnitine and/or ${\gamma}$ -aminobutyric acid (GABA) supplementation on lipid profiles and some immune related nutrient in mice. Balb/c male mice were orally treated with either an AIN-76 diet (Con), a control diet plus carnitine (CS, 0.5 g/kg bw), a control diet plus GABA (GS, 0.5 g/kg bw) or a control diet plus carnitine plus GABA (CGS, 0.25 g/kg bw, respectively) for 6 weeks. There were no significant differences in feed consumption, energy intake, body weight gain or feed efficiency ratio among the groups during the experimental period. However, abdominal fat deposits were smaller in CS, GS and CGS groups compared with the Con group. Serum and liver triglycerides also were lower in CS, GS and CGS and serum total cholesterol was significantly lower in the CGS group compared with the Con group. Serum LDL cholesterol was lower in the CGS group and liver HDL cholesterol was significantly higher in the CS group compared with Con group. In serum, stearic acid and selecholeic acid were lower, but arachidic acid was higher in the CS group. Liver stearic acid was higher but oleic acid lower in CGS group compared with Con group. In carnitine supplemented groups, serum and liver nonesterified carnitine (NEC), acidsoluble acylcarnitine (ASAC), total carnitine (TCNE) concentrations were higher in only the CS group, not CGS group. Serum vitamin A and E concentrations were not different among the groups. These results may suggest that carnitine and/or GABA supplementation improves lipid profiles in mice, but did not affect the immune-related nutrients that we measured under the experimental conditions of this study.
