  • We analyzed saccharide by dividing and comparing Monosaccharide, Disaccharide and sugar Alcohol. At first, Glucose had outstanding contained quantity of ASI 7114 with 81.11 g/l even comparing with other mushrooms for medical use and edibility. And 119.98 g/l of Fructose was observed at Hericium erinaceum that was more contained quantity than Flammulina velutipes and Lentinus edodes. But, the most contained quantity observed in Ganoderma lucidum was ASI 7015 with 15.70 g/l that was the level of 1/8 approximately against Hericium erinaceum. Ribose was found at low level generally that was hardly contained. Xylose was also observed low level. ASI 7004 was detected at 0.96g/l that was the most content with imperceptible difference by comparing with other mushrooms for medical use and edibility. Next, 35.21 g/l of Trehalose, disaccharide was observed at Agaricus bisporus that was around 11 times of content than ASI 3.09 g/l that was the most content of Ganoderma lucidum. For ${\alpha}$-Lactose, Sparassis crispa has the most amount of 3.38 g/l that was around 12.5 times of ASI 7060 0.27 g/l that was the most content of Ganoderma lucidum. For Glycerol, sugar alcohol, 64.74 g/l was observed at Pleurotus eryngii. We knew it was around 8 times of ASI 7004 8.61 g/l that was the most content of Ganoderma lucidum. 0.72 g/l of Solbitol was observed at Flammulina velutipes. We knew it was around 2times of ASI 7003 0.31 g/l that was the most content of Ganoderma lucidum. Moreover most of Ganoderma lucidum didn't contain Solbitol. 2.96 g/l of Mannitol was observed at Agaricus bisporus. that was the most content among other mushrooms. Also Mannitol was contained in Lentinus edodes and leurotus cornucopiae only. Even Ganoderma lucidum didn't have Mannitol. At last, as a result of myo-Inosito content analysis, it was seemed not to be involved in any of mushrooms.

  • To assess the effect of pinitol supplementation and strength training for two weeks on the anaerobic capacity during and after exercise, and improvement of glucose metabolism during the recovery period of muscular fatigue with repeated acute bouts of cycling exercise, a total of 24 healthy young men were recruited and randomly and equally divided into three groups; pinitol supplementation group (PSG), placebo group (PLG), and control group (CON). Using a randomized double-blinded design, subjects in PSG were provided pinitol supplement, consumed orally 1.2 g/day, and participated in the resistance exercise program and cycling exercise for two weeks. Subjects in PLG underwent the same protocol as those in PSG but consumed the same amount of placebo. No supplementation and exercise program was given to CON. Before and after the intervention, all subjects were tested for their anaerobic capacities evaluated by Wingate test twice separated by 30 min. During the test, peak anaerobic power (PP), mean anaerobic power, total work, and fatigue index were evaluated During resting and recovery, blood samples were drawn and plasma pinitol, myo-inositol, chiro-inositol, insulin, free fatty acid, glucose, and lactate levels were analyzed After two weeks, PP and relative PP of the second biking were improved from the first biking in PSG only (p<0.05). No changes were found in all other variables of Wingate test in all groups. No statistical differences between groups and pre- and post-intervention were observed in concentrations of pinitol, myo-inositol, and chiro-inositol, but pinitol concentration was higher during recovery compared to the baseline in all groups and testings (p<0.05). Lactate level during recovery was higher than the resting level, but no other blood parameters were significantly changed. In conclusion, two weeks of pinitol supplementation in conjunction with short duration of anaerobic training in healthy young men did not induce any obvious benefits in terms of anaerobic capacity and energy metabolism Individual and/or population susceptibility may be one factor responsible for adopting pinitol supplementation.

  • MicroRNAs (miRNAs) are highly conserved, short non-coding RNAs that regulate gene expression at the posttranscriptional level. Although many miRNAs are identified in muscles and muscle cells, their individual roles are still not fully understood. In the present study, we investigated a muscle highly-expressed miRNA, miR-127-3p, in C2C12 myoblasts and tissues of goats with different muscle phenotypes (Boer vs Wushan black goats). Our results demonstrated that i) miR-127-3p was extensively expressed in tissues of goats; ii) miR-127-3p was higher expressed in muscle, spleen, heart, and skin in the muscular goats (Boer goats) than the control (Wushan black goats). Then we further characterized the dynamical expression of miR-127-3p, MyoD, MyoG, Myf5, Mef2c, and Myosin in the proliferating and differentiating C2C12 myoblasts at day of 0, 1, 3, 5, and 7 in culture mediums. Especially, we found that miR-127-3p was significantly higher expressed in the proliferating than differentiating cells. Our findings suggest that miR-127-3p probably plays roles in the proliferation and differentiation of myoblasts, which further underlies regulation of muscle phenotype in goats.

  • It is already well known that castration improves marbling quality but exact timing of castration is still highly debated in beef cattle production industry. After castration, blood hormonal changes occur in steer and objective of this study was to investigate the effects of growth hormone (GH) levels on adipocyte differentiation in stromal vascular cells (SVCs) and transdifferentiation into adipocytes in C2C12 myoblasts. Total GH concentrations were measured via enzyme-linked immunosorbent assay (ELISA) in 24 male calves and 4 female calves. Cell proliferation, cellular triglyceride (TG) accumulation, and the cell's lipolytic capability were measured in C2C12 myoblasts and SVCs. Myogenic, adipogenic, and brown adipocyte-specific gene expression was measured via real-time polymerase chain reaction (PCR) using SYBR green. Serum GH levels were the highest in late-castrated calves. Treatment with 5 ng/mL GH resulted in greater TG accumulation as well as increased CCAAT-enhancer-binding protein (C/EBP)α and peroxisome proliferator-activated receptor (PPAR)γ expression compared to that after treatment with 15 ng/mL GH. Treatment with 5 ng/mL GH also resulted in lower myogenin (myo)G and myoD expression compared to that after treatment with 15 ng/mL GH. The expression of bone morphogenetic protein (BMP) 7 after treatment with 5 ng/mL GH was higher than that after treatment with 15 ng/mL GH. But carcass characteristics data showed no significant difference between early and late castrated steers. Therefore, our results indicate that castration timing does not seem to be inevitable determinate of carcass qualities, particularly carcass weight and marbling score in Hanwoo beef cattle.

  • Ginseng is traditionally cultivated worldwide in cold continental climates. It is now also being cultivated in maritime environments such as New Zealandis. This paper reports a number of growth and quality parameters for plants grown under those conditions over two growing seasons and the intervening winter dormant period. While shoot biomass peaked mid-summer, in contrast, root biomass peaked late autumn/early winter. Starch, sucrose, fructose, glucose and inositol were detected in the roots. Starch concentrations were highest in early autumn (mean 470 mg $g^{-1}$ dry weight) and lowest in mid spring (218 mg $g^{-1}$ dry weight). Sucrose concentrations were low during early summer until late autumn but increased rapidly with the onset of winter and peaked during mid spring (168 mg $g^{-1}$ dry weight). Fructose and glucose concentrations were similar and peaked in late spring (5.3 and 6.2 mg $g^{-1}$ dry weight). Inositol concentrations peaked in mid summer (1.7 mg $g^{-1}$ dry weight). Starch/sugar ratios were high during summer and autumn and low during winter and spring. Ginsenoside concentrations and profiles showed that the six major ginsenosides, Rgl, Re, Rb1, Rc, Rb2 and Rd, were present, but Rf was absent. Concentrations did not vary with sampling date. The most abundant ginsenosides were Re (15.9 to 17.5 mg $g^{-1}$ dry weight) and Rb1 (10.7 to 18.1 mg $g^{-1}$ dry weight). Combined, they accounted for < $75{\%}$ of total ginsenoside concentrations. Limited taste tests indicated that highest root quality occurred during late autumn, after the shoots had senesced. However, quality could not be related to plant chemistry.

  • The debranching enzyme of Nostoc punctiforme (NPDE) is a novel enzyme that catalyzes the hydrolysis of $\alpha$-1,6-glycosidic linkages in starch, followed by the sequential hydrolysis of $\alpha$-1,4-glycosidic linkages. The debranching activity of NPDE is highly specific for branched chains with a degree of polymerization (DP)>8. Moreover, the rate of hydrolysis of $\alpha$-1,4-linkages by NPDE is greatly enhanced for maltooligosaccharides (MOs) with a DP>8. An analysis of reaction mixtures containing various starches revealed the accumulation of maltooctaose (G8) with glucose and maltose. Based on the novel enzymatic properties of NPDE, an MO mixture containing more than 60% G8 with yield of 18 g G8 for 100 g starch was prepared by the reaction of NPDE with soluble starch, followed by ethanol precipitation and gel permeation chromatography (GPC). The yield of the G8-rich mixture was significantly improved by the addition of isoamylase. In summary, a 4-step process for the production of a G8-rich mixture was developed involving the enzymatic hydrolysis of starch by NPDE.

  • A feeding experiment was conducted using juvenile Korean rockfish (Sebastes schlegeli) to evaluate supplemental vitamin premix in a test diet containing fish meal as protein source for nutritional study. Four vitamin premixes were prepared by adjusting different quantity and combination of vitamins. Each vitamin premix contained (mg/kg diet) : premix-1 : ascorbic acid, 2666 ; a-tocopheryl acetate, 417 ; thiamin, 60 ; riboflavin, 200 ; pyridoxine, 40 ; niacin, 800 ; Ca-D-pantothenate, 280 ; myo-inositol, 4000 ; D-biotin, 6 ; folic acid, 15 ; p-amino-benjoic acid, 400 ; mennadione, 40 ; A, 16 ; $D_3$, 0.1 ; choline chloride, 8000 ; cyanocobalamin, 0.09 ; premix-2 : ascorbic acid, 270 ; a-tocopheryl acetate, 189 ; thiamin, 13.5 ; riboflavin,, 27 ; pyridoxine, 13.5 ; niacin, 135 ; Ca-D-pantothenate, 135 ; myo-inositol, 135 ; D-biotin, 1. 4 : folic acid, 4.9 ; mennadione, 5.4 : A, 5.4 ; $D_3$, 2.2 ; choline chloride, 3000 ; cyanocobalamin, 0.05 ; premix-3 : ascorbic acid, 570 ; a-tocopheryl acetate, 107 ; thiamin, 20 ; riboflavin, 14.3 ; pyridoxine, 14.3 ; niacin, 71,3 ; Ca-D-pantothenate, 57 ; myo-inositol, 456 ; D-biotin, 0.7 ; folic acid, 2.9 ; p-aminobenjoic acid, 285 ; mennadione, 5.7 ; A, 5.7 ; $D_3$, 1.1 ; choline chloride, 1500 ; cyanocobalamin, 0.03 ; premix-4 : ascorbic acid, 190 : a-tocopheryl acetate, 36 ; thiamin, 6.7 ; riboflavin, 4.8 ; pyridoxine, 4.8 ; niacin, 23.8 ; Ca-D-pantothenate, 19 ; myo-inositol, 152 ; D-biotin,0.2 ; folic acid, 1 ; p-aminobenjoic acid, 95 ; mennadione, 1.9 ; A, 1.9 ; $D_3$, 0.4 ; choline chloride, 500 ; cyanocobalamin, 0.01. Triplicate groups of the 50 fish averaging 4.25 g were fed one of four isoproteic ($47\%$) and isolipidic ($9\%$) experimental diets to satiation twice a day for 10 weeks. Weight gain, feed efficiency and protein retention in fish fed the diet with vitamin premix-1 were significantly higher than those in fish fed the other diets (P<0.05). Moisture, protein and lipid contents of muscle and whole body were not affected by different dietary vitamin premix (P>0,05). These results indicate that premix-1 can be used to adequate supplemental vitamin premix in test diet containing fish meal as protein source for juvenile Korean rockfish.

  • The present work aims to study the induction of somatic embryogenesis in cork oak (Quercus suber L.) from immature zygotic embryos and young apical leaves obtained from 2-month-old seedlings through acorn germination on sterilized peat. The immature zygotic embryos were grown for 1 month on the mineral solution of MS in the presence of 4.52 µM 2,4-D and 30 g/L sucrose. They were then transferred to the same mineral solution with no added growth regulators. In the third subculture, yellow somatic embryos, characterized by two voluminous cotyledons, were differentiated from the radicle of the immature zygotic embryos. The induction of somatic embryogenesis in young leaves required a series of transfers on different culture media containing 30 g/L sucrose and 100 mg/L myo-inositol. Secondary or recurrent somatic embryogenesis occurred within the immature somatic embryo radicles after 1 month of culture on growth regulator-free medium containing WPM macronutrients, MS micronutrients, and vitamins.

  • Thermal stress due to extreme changes in the thermal environment is a critical issue in cattle production. Many previous findings have shown a decrease in feed intake, milk yield, growth rate, and reproductive efficiency of cattle when subjected to thermal stress. Therefore, selecting thermo-tolerant animals is the primary goal of the efficiency of breeding programs to reduce those adverse impacts. The recent advances in molecular genetics have provided significant breeding advantages that allow the identification of molecular markers in both beef and dairy cattle breeding, including marker-assisted selection (MAS) as a tool in selecting superior thermo-tolerant animals. Single-nucleotide polymorphisms (SNPs), which can be detected by DNA sequencing, are desirable DNA markers for MAS due to their abundance in the genome's coding and non-coding regions. Many SNPs in some genes (e.g., HSP70, HSP90, HSF1, EIF2AK4, HSBP1, HSPB8, HSPB7, MYO1A, and ATP1A1) in various breeds of cattle have been analyzed to play key roles in many cellular activities during thermal stress and protecting cells against stress, making them potential candidate genes for molecular markers of thermotolerance. This review highlights the associations of SNPs within these genes with thermotolerance traits (e.g., blood biochemistry and physiological responses) and suggests their potential use as MAS in thermotolerant cattle breeding.

  • In this study, we verified the 1-1-diphenyl-2-picryl-hydrazyl radical scavenge, 2,2'-azinobis(3-ethylbenzothiazoline-6-sulfonic acid) radical scavenge, elastase, tyrosinase inhibitory effect by using the solvent fractions of Maekmoondong-tang hot water extract. As a result, the ethyl acetate fraction (MW-EA) showed the highest inhibitory activity. In cell-based assays, MW-EA treatment confirmed a 34% ($100{\mu}g/mL$) efficacy in reactive oxygen species inhibitory activity, and at the same concentration, MMPs showed more than 50% inhibition and tyrosinase inhibited 25% ($50{\mu}g/mL$). Therefore Maekmoondong-tang is considered high development potential as a material to improve the skin.
