  • This study was conducted to investigate effects of different levels of seleniferous whole crop barley (WCB) supplementation on performance, and blood characteristics as physiological responses in growing pigs. A total of 20 cross-bred pigs ((Landrace ${\times}$ Yorkshire) ${\times}$ Duroc) were divided into 4 treatments of 5 pigs each and experimental period lasted for 6 weeks. They were fed diets containing 0.1 (non-seleniferous WCB as controls), 0.2, 0.4, and 0.6 mg/kg levels of selenium (Se) by supplementing seleniferous WCB, and non-seleniferous or seleniferous WCB was formulated to 5% level in total ration. The diets were isonitrogenous (18% crude protein) and isocaloric (3,500 kcal/kg digestible energy) across treatments. Increasing levels of seleniferous WCB supplements did not affect feed intake and BW gain, and blood total protein concentration was (p<0.05) significantly higher for 0.2 mg/kg Se treatments than for controls. On d 14, blood albumin concentration was higher (p<0.05) for seleniferous WCB supplemented groups than for control group. Contrarily, blood glucose concentration was tended to be higher for controls than for seleniferous WCB groups. Blood total lipid concentration was significantly (p<0.05) lowered with increasing levels of seleniferous WCB. Serum glutamic-oxaloacetic transaminase and glutamic-pyruvic transaminase did not have any difference among treatments. It was tended that blood total cholesterol and triglyceride were lowered with increasing levels of seleniferous WCB. Blood Se concentration was significantly (p<0.05) increased with increasing levels of seleniferous WCB. The results indicate that Se present in seleniferous WCB had favorable effects on blood characteristics and blood Se increased by supplementing seleniferous WCB implies not only a good intestinal absorption of Se present in WCB but also the possibility of Se transfer into tissues.

  • The purpose of this study was to investigate the effects of a butanol fraction of fraction of Alisma canaliculatum All. Braun et Bouche (Ac), and of selenium (Se), on plasma gllucose and lipid levee in streptozotocin (STD-induced diabetic rats. Male Sprague-Dawley rats, fed the AIN-93 recommended diet, were divided into five groups: a non-diabetic control group (no STZ treatment), and four 572-induced diabetic groups which consisted of a diabetic-control group, an Ac-treated group, an Ac-Se treated group, and a Se-treated group. Diabetes was induced in the rats by an injection of STZ into the tail vein at a dose of 45 mg/kg body weight. The butanol (BuOH) fraction of Ac was orally administered at a rate of 400 mg/kg body weight for 21 days to both the Ac and Ac-Se groups. The supplementation of selenium in the Se and Ac-Se groups was achieved by adding (freshly, every day) 2 mg of Se as Na$_2$SeO$_3$ per kg of feed. The rats'body weights and hematocrit (Hct) levels were measured, along with plasma levels of glucose, insulin, cholesterol, HDL-cholesterol, triglyceride (TG), and free fatty acids (FFA). Aminotransferase activities were also analyzed. The non-diabetic rats gained weight, while the diabetic rats lost weight - except in the Ac-Se group, which maintained their initial weight. The blood glucose levels of the Ac group and the Se group were significantly lower than for the diabetic-control group. The plasma triglyceride levels were lowered when both Ac and Se were administered to diabetic rats. The concentrations of plasma FFA in the Ac-Se group were significantly lower compared with the diabetic-control group. Plasma cholesterol levels and alanine aminotransferase activity in the Ac, Ac-Se, and Se groups were significantly lower when compared with the diabetic-control group. Aspartate aminotransferase activity was significantly lower in the Se group compared to the other diabetic groups. These data show that treatment with a butanol fraction of Ac in combination with Se has no synergistic effect. Plasma glucose levels tended to be low when Se was administered to diabetic rats. Supplementation of Se in diabetic rats did not elicit a significant increase in plasma insulin levels or result in hypolipemic effects.

  • Atherosclerosis is a chronic vascular inflammatory disease in which plaque builds up in the arteries and impairs blood flow. This can lead to heart disease and stroke. Since most people do not have any symptoms until the artery is severely narrowed, early detection of atherosclerosis is critical. In this paper, in order to effectively detect atherosclerotic lesions in tube-shaped blood vessels, polar conversion is applied to MRI images based on the vessel center. We then propose a SE-LSTMNet model using continuous signal information for each angle of a polar coordinate image. The trained model showed classification performance of 0.9194 accuracy, 0.9370 sensitivity, 0.8796 specificity, 0.8700 F1 score, and 0.9719 AUC on the validation data.

  • Human blood selenicum(Se) level depends on the Se content and bioavailablilty of foods. In countries where the soil has low Se content, the differences of Se intake and blood Se concentration are shown according to the type of diet. In this study, Se status of women eating an average German diet(175 German healthy women) and wholesome nutrition group(243 women) were studied. There were significant differences in wholeblood and plasma Se levels between the two groups. In average German diet group, mean wholeblood Se concentration was 84.97ug/l and plasma Se concentration was 75.02ug/l. In wholesome nutrition group mean wholeblood Se concentration and plasma Se concentration with Se levels, correlation analysis was conducted between Se concentration and BMI, age and daily food intake. BMI and age did not correlate significantly with wholeblood and plasma Se levels. In wholesome nutrition group, serum and wholeblood Se levels had significant correlation with fish intake.

  • This study was conducted to investigate effects of feeding seleniferous whole crop barley silage (WCBS) on growth performance and blood characteristics in growing Hanwoo steers. A total of 20 growing Hanwoo steers, initially weighing on average 208.8 kg of body weight, were used and treatments were consisted of 1) controls : 0.1 mg/kg Se, 2) T1 : 0.3 mg/kg Se, 3) T2 : 0.9 mg/kg Se by combining seleniferous and/or non-seleniferous WCBS, and 4) T3 : 0.9 mg/kg Se of inorganic Se treatment. Five steers were allocated to each treatment, and the trial was lasted for 90 days. All experimental diets were included to 30% of combination of seleniferous and/or non-seleniferous WCBS, and in T3 diet, sodium selenite that corresponds to 0.9 mg/kg Se was added to control diets. Also, the diets were isonitrogenous and isocaloric among treatments. Dietary level and type of selenium did not affect feed intakes and daily gain, and blood glucose concentration was significantly (p<0.05) lower for controls than T1 and T2 treatments. Blood total lipid concentration was significantly (p<0.05) decreased with increasing levels of dietary selenium, and also that of T2 and T3 was significantly (p<0.05) lower than controls. LDL-cholesterol concentration was significantly (p<0.05) lower for treatments including dietary selenium than controls, and also blood triglyceride concentration was significantly (p<0.05) lower for T2 than controls. Overall, it was tended that feeding seleniferous WCBS or inorganic Se increased blood IgG concentration, and in the same dietary selenium levels, T2 treatment was higher for IgG than T3 group (p>0.05). Blood selenium concentration was significantly (p<0.05) increased by feeding increasing levels of seleniferous WCBS, but there was no significant difference between controls and T3 group. These results showed that feeding seleniferous WCBS to growing Hanwoo steers was responsible for saccharide and lipid metabolism, and in particular, it reduced their total lipid and blood LDL-cholesterol concentrations. Furthermore, selenium present in seleniferous WCBS rather than inorganic selenium was better available in intestinal absorption, and it might help to enhance immunity in growing and younger stages of Hanwoo steers.

  • A study was conducted to monitor the changes in serum protein profile, cholesterol and blood glucose during endotoxic shock in buffalo calves and also to assess the role of prophylactic supplementation of vitamin E and selenium in alleviating the endotoxic effects. Fifteen male buffalo calves (6-8 months of age) were divided into three groups: Group I (control)-infused with 0.9% saline solution; Group II-infused with E. coli endotoxin at 5${\mu}g/kg$ body weight in normal saline solution; Group III- supplemented prophylactically with 250 mg vitamin E and 7.5 mg selenium by i/m injections at weekly intervals for one month prior to the induction of endotoxic shock. The blood samples were collected at 0, 1, 3, 6, 9, 12, 24, 48 and 72 h after the induction of shock. Endotoxin caused a significant (p<0.05) hypoproteinemia from 3-12 h post infusion in group II but this hypoproteinemia was less pronounced and only from 3-9 h post infusion in vitamin E and selenium supplemented calves. Hypoglycemia was observed in group II from 3-24 h and blood glucose level returned to normal at 72 h. However hypoglycemia was mild in group III and blood glucose returned to normal at 48h. Hypocholesterolaemia and hypoalbuminemia were found in both groups II and III but these changes were less pronounced in group III i.e. vitamin E and Se supplemented calves. Serum electrophoretic protein patterns of group III were quite similar to those of control group but animals of group II had different electrophoretic pattern. It was concluded that the antioxidant effects of vitamin E and Se prevent the liver against oxidative stress during endotoxic shock.

  • This study was conducted to investigate the effects of feeding seleniferous whole crop barley silage (WCBS) on the growth performance, blood and carcass characteristics, and tissue selenium deposition infinishing Hanwoo steers. A total of 20 growing Hanwoo steers were selected and assigned to one of the following feed groups: control (0.1 ppm Se), T1 (0.3 ppm Se), T2 (0.9 ppm Se), and T3 (0.9 ppm of inorganic Se). Five steers were allocated to each treatment group, and the trial lasted for 90 days. All experimental diets combined seleniferous and/or non-seleniferous WCBS up to a ratio of 30%. For the T3 diet, 0.9 ppm Se in the form of sodium selenite was added to the control diet. Dietary level and type of selenium did not affect feed intake and body weight gain. Blood total lipid and triglyceride concentrations were significantly (p<0.05) lower in the T2 group than in control. Blood immunoglobulin G concentration increased significantly (p<0.05) with increasing levels of dietary selenium; concentrations were significantly (p<0.05) higher in T2 and T3 than in control. Blood selenium concentration was the highest (p<0.05) in T2. No significant difference was observed in dressing rate, ribeye area, marbling score, meat color and fat color. Further, no association was found between levels and chemical form of dietary selenium and quality and quantity of meat. To the contrary, tissue selenium content in kidney, liver, and hind leg increased significantly (p<0.05) with increasing levels of selenium; however, feeding inorganic selenium did not introduce a significant increase in tissue selenium content of finishing Hanwoo steers. The results indicated that the selenium present in seleniferous WCBS was an effectively absorbable selenium source, suitable for increasing tissue selenium content in beef. Approximately 100 g of hind leg muscle from steers fed on the T2 diet met approximately 69% of the recommended daily selenium requirements.

  • Flow characteristics of blood flow in a micro channel were investigated experimentally using a micro-PIV (Particle Image Velocimetry) velocity field measurement technique. The main objective of this study was to understand the real blood flow in micron-sized blood vessels. The Reynolds number based on the hydraulic diameter of micro-channel for deionized (DI) water was about Re=0.34. For each experimental condition, 100 instantaneous velocity fields were captured and ensemble-averaged to get the spatial distributions of mean velocity. In addition, the motion of RBC (Red Blood Cell) was visualized with a high-speed CCD camera. The captured flow images of nano-scale fluorescent tracer particles in DI water were clear and gave good velocity tracking-ability. However, there were substantial velocity variations in the central region of real blood flow in a micro-channel due to the presence of red blood cells.
