        This study aimed to produce fermented soy-powder milk (FSPM) with Lactobacillus plantarum P1201 and to evaluate its anti-obesity activity. Isoflavone and conjugated linoleic acid (CLA) of unfermented soy-powder milk (UFSPM) and FSPM and were analyzed via high-pressure liquid chromatography (HPLC) and gas chromatography (GC). Their inhibitory activities against α-glucosidase, α-amylase, and pancreatic lipase were assayed. Their anti-obesity activities were evaluated on the basis of their inhibitory effects on adipocyte differentiation in 3T3-L1 cells, and the expression of mRNAs associated with adipogenesis and lipid metabolism were analyzed via real time-polymerase chain reaction (RT-PCR) and quantitative PCR (qPCR). FSPM with L. plantarum P1201 increased the isoflavone aglycones (daidzein, glycitein, and genistein) content and produced CLA in soy-powder milk (SPM), both of which possessed bio-activity. Both UFSPM and FSPM showed dose-dependent inhibitory activity for α-glucosidase, α-amylase, and pancreatic lipase. FSPM, but not UFSPM, suppressed adipogenesis in 3T3-L1 cells and reduced their triglyceride content by 23.1% after treatment with 1,000 μg/mL of FSPM, compared with the control group. The anti-obesity effect of FSPM can be attributed to CLA and isoflavone aglycones, which targeted CCAAT/enhancer binding protein α (C/EBP-α) and down-regulated lipoprotein lipase (LPL), adiponectin, adipocyte fatty acid-binding protein (aP2), fatty acid synthase (FAS), and acetyl CoA carboxylase (ACC) mRNA. Furthermore, FSPM enhanced the inhibitory activity of glucosidase and pancreatic enzymes and anti-obesity activity. Further studies are required to investigate whether the anti-obesity effect of FSPM persists in an in vivo mouse model of diet-induced obesity.

        In this study, we evaluated the antidiabetic effect of a submerged culture of Ceriporia lacerata mycelium (CL01) on hematological indices, as well as protein and mRNA expression of the insulin-signaling pathway, in db/db mice. After CL01 was administrated for 4 weeks, blood glucose levels decreased consistently, and plasma insulin and c-peptide levels each decreased by roughly 55.8%, 40% of those in the negative control (p<0.05). With regard to HOMA-IR, an insulin resistance index, insulin resistance of the CL01-fed group improved over that of the negative control group by about 62% (p<0.05). In addition, we demonstrated that the protein expression levels of pIR, pAkt, pAMPK, and GLUT4 and the mRNA expression levels of Akt2, IRS1, and GLUT4 in the muscle cells of db/db mice increased in the CL01-fed group compared to the corresponding levels in the control group. These results demonstrate that CL01 affects glucose metabolism, upregulates protein and gene expression in the insulin-signaling pathway, and decreases blood glucose levels effectively by improving insulin sensitivity. More than 90% of those who suffer from type 2 diabetes are more likely to suffer from hyperinsulinemia, hypertension, obesity, and other comorbidities because of insulin resistance. Therefore, it is possible that CL01 intake could be used as a fundamental treatment for type 2 diabetes by lowering insulin resistance, and these results may prove be useful as basic evidence for further research into the mechanisms of a cure for type 2 diabetes.

        It is necessary to alleviate environmental and economic disadvantages of fossil fuels for global warming. Among the conceivable options, the use of plant biomass for the production of bioethanol is considered as a potential alternative for fossil fuels. Plant biomass that contains lignocellulose for bioethanol production has recently emerged as biofuel feedstock because of its sustainable and environment-friendly properties. However, lignin inhibits the hydrolysis process and the lignin recalcitrance in ethanol conversion remains in a problem. The attempt for down-regulating enzymes involved in lignin biosynthesis is one of attractive strategy to reduce the lignin contents. Recently, Brachypodium distachyon has been proposed as an alternative monocotyledon model species. The close phylogenetic relationship of Brachypodium with other grasses suggests that the Brachypodium may be useful for structural and functional genomic studies in these species. Brachypodium, standard line Bd21, was subjected to irradiation at doses of 50, 100, 150, 200, and 250 Gy. Phenotypes were investigated using M0:2 population. Through histochemical analysis using phloroglucinol, 25 M2 putative lignin deficient mutants were selected. Depend on the phenotypic and histochemical data, mutants were selected and used for measuring lignin content. Total lignin content was measured using the acetyl bromide (AcBr). Mutant #142-3-1 contains 16.9 (mg/g dry cell wall) of total lignin and the lignin level was significantly reduced (87.9%) compared to wild-type (19.23 mg/g dry cell wall). Additionally, Mutant line #2259-1-2 reduced lignin level at 94.4% (18.15 mg/g dry cell wall) in comparison to wild-type. The enzymatic hydrolyses in lignin deficient lines have been performing with the time courses. Lignin composition, cell wall carbohydrates, and genetic analysis in mutant lines will be discussed.

        Slaughter of cattle, pigs, and chickens has increased continuously. In particular, slaughter of chickens has been grown up about 150% in 2010 than that in 2003, that is approximately 120,000 tons. All of them are underwent consigned treatment even though those can be used as a resource and an energy source. With this regards, THR (Thermal Hydrolysis Reaction) leads to reduce water content drastically (<30% in sludge cakes). In addition, Dehydrated solid would be re-used as solid fuels (SRF) as well. In this study, We have applied THR to a plant (10 ton/day) on the basis of our lab and pilot results. Water content of sludge cakes showed with a ranges of 30 to 40% after solid-liquid separation. Dairy SRF produced 1.5 ton/day and its heat capacity for SRF has 6,500 kcal/kg. This gave the steam produced about 12 ton/day throughout the plant operation, suggesting that THR system would expect energy savings.

        Brachypodium has been focused as new model plant for grass species. Like small size, small room requirement, and fast growth, Brachypodium shows numerous advantages as a model plant. Brachypodium is a typical grass at the genome level, which also exhibits an overall similarity of gene content and gene families when compared with rice (Oryza sativa) and sorghum (Sorghum bicolor) genomes. Brachypodium is an excellent material for structural and functional genomic studies in grass species. Targeting-Induced Local Lesions IN Genomes (TILLING) is a high-throughput technique and an approach for reverse genetics study. Moreover, it has been wildly utilized to find induced mutation. Bradi3g45515 is orthologue of the cellulose synthase-like HvCslF8 in barley. For TILLING library construction, 384 M2 Brachypodium mutants induced by chronic-gamma irradiation were used. Single nucleotide polymorphysm (SNP) and small deletion in Bradi3g45515 were searched through TILLING analysis. Template DNA for PCR reaction were prepared according to two dimensional pooling (eightfold) strategy. Heteroduplex DNA was digested by SURVEYOR nuclease (TRANSGENOMIC) and the DNA fragment was detected using polyacrylamide gel electrophoresis. Positive signal appeared at polyacrylamide gel from more than 4 lines and their Bradi3g45515 region were sequenced. SNP(s) were identified in 509-2 and 677-3 mutant line. Cellulose content and/or cell wall materials content will be measured using these mutants.

        Agastache rugosa, a member of the mint family (Labiatae), is a perennial herb widely distributed in East Asian countries. It is used in traditional medicine for the treatment of cholera, vomiting, and miasma. This study assessed the genetic diversity and population structures on 65 accessions of Korean mint A. rugosa germplasm based on inter simple sequence repeat (ISSR) markers. The selected nine ISSR primers produced reproducible polymorphic banding patterns. In total, 126 bands were scored; 119 (94.4%) were polymorphic. The number of bands generated per primer varied from 7 to 18. A minimum of seven bands was generated by primer 874, while a maximum of 18 bands was generated by the primer 844. Six primers (815, 826, 835, 844, 868, and 874) generated 100% polymorphic bands. This was supported by other parameters such as total gene diversity (HT) values, which ranged from 0.112 to 0.330 with a mean of 0.218. The effective number of alleles (NE) ranged from 1.174 to 1.486 with a mean value of 1.351. Nei's genetic diversity (H) mean value was 0.218, and Shannon's information index (I) mean value was 0.343. The high values for total gene diversity, effective number of alleles, Nei's genetic diversity, and Shannon's information index indicated substantial variations within the population. Cluster analysis showed characteristic grouping, which is not in accordance with their geographical affiliation. The implications of the results of this study in developing a strategy for the conservation and breeding of A. rugosa and other medicinal plant germplasm are discussed.

        Anomalous X-ray pulsars (AXPs) are thought to be magnetars which are young isolated neutron stars with extremely strongmagnetic fields of >1014 Gauss. Their tremendous magnetic fields inferred from the spin parameters provide a huge energyreservoir to power the observed X-ray emission. High-energy emission above 0.3 MeV has never been detected despiteintensive search. Here, we present the possible Fermi Large Area Telescope (LAT) detection of γ-ray pulsations above 200MeV from the AXP, 1E 2259+586, which puts the current theoretical models of γ-ray emission mechanisms of magnetars intochallenge. We speculate that the high-energy γ-rays originate from the outer magnetosphere of the magnetar.
