This study evaluated the potential antioxidant and antidiabetic properties in vitro of four millet grain varieties cultivated South Korea. The free fractions were tested for their total capacity using 2,2'-azino-bis (3-ethylbenzothiazoline-6-sulfonic acid) diammonium salt (ABTS+) 2,2'-diphenyl-1-picrylhydrazyl (DPPH) radical scavenging assays, followed by α-glucosidase, α-amylase, advanced glycation endproducts (AGEs) formation inhibition assays. phenolics, flavonoids, condensed tannins...
Rotifers of Class Bdelloidea are abundant freshwater invertebrates known for their remarkable ability to survive desiccation and lack males meiosis. Sequencing annotation approximately 50-kb regions containing the four hsp82 heat shock genes bdelloid Philodina roseola, each located on a separate chromosome, have suggested that its genome is degenerate tetraploid. In order determine whether similar structure exists in distantly related P. roseola if tetraploidy was established before two...
HrpNEP, from the gram-negative pathogen, Erwinia pyrifoliae, is a member of harpin group proteins, inducing pathogen resistance and hypersensitive cell death in plants. When hrpNEP gene driven by OsCcl promoter was introduced into tobacco plants via Agrobacterium-mediated transformation, their to necrotrophic fungal Botrytis cinerea, increased. Resistance B. cinerea correlated with enhanced induction SA-dependent genes such as PR-1a, PR2, PR3 Chia5, JA-dependent PR-1b, related ethylene...
Biodegradation of endosulfan (α and β) pendimethalin by Bacillus safensis strain FO-36bT, subtilis subsp. inaquosorum KCTC 13429T cereus ATCC14579T isolated from pesticides-polluted soil was studied in mineral salt medium. Endosulfan were incubated with the three bacterial strains samples drawn at various intervals for GC analysis. Representative subject to GC–MS The loss initial concentrations, 0.663 mM endosulfan), 0.319 (β endosulfan) 1.423 (pendimethalin), monitored used compute...
This study aimed to evaluate the median lethal concentration (LC50), acute (24 and 96 h) sublethal (35 d) effects of deltamethrin, a synthetic pyrethroid pesticide on hormonal enzymological responses in an Indian major carp, Labeo rohita. In this study, LC50 values deltamethrin for 24 h were found be 0.438 0.38 mg L—1, respectively. During (0.438 L−1) (1/10th value, 0.0438 studies, plasma cortisol prolactin levels significantly increased (p < 0.05). When compared with control group,...
This study was performed to investigate the residual characteristics, safety assessment, and pre-harvest interval (PHI) of spiromesifen chromafenozide in lettuce (Latuca sativa L.) perilla (Perilla frutescens (L.) Britton) leaves. Samples were harvested periodically, extracted using QuEChERS method, analyzed by LC-MS/MS. Average recoveries its metabolite BSN2060-enol ranged from 80.6 107.9%, with relative standard deviation < 10%. Spiromesifen cromafenozide initial residues dissipated 81.45...
Six representative Korean strains of streptomycetes (S33, S27, S71, S63, S77, and S78) that were pathogenic to potato characterized based on phenotypic properties, analysis 16S rRNA genes, production thaxtomin A, presence nec1 ORFtnp gene homologs. Strains S33 S27 had typical characteristics Streptomyces scabies S. turgidiscabies, respectively, producing A hybridizing genes ORFtnp. Strain S71 produced phylogenetic properties similar those acidiscabies, except having a greater minimum growth...
The Japanese Erwinia strain Ejp617 is a plant pathogen that causes bacterial shoot blight of pear in Japan. Here, we report the complete genome sequence isolated from Nashi pears Japan to provide further valuable insight among related species.
토양 중 잔류하는 chlorpyrifos의 오이 흡수 이행과 잔류분포를 조사하기 위하여 생장상 내 실내시험과 시설재배 포장에서의 실외시험을 실시하였다. 실내 및 실외시험 기간에 분해 반감기는 각각 25.8~73.0일과 32.4~42.3일로 비슷하였다. 실내시험 잔류량은 정식 후 15일까지 증가하다가 그 이후로 감소하는 양상을 나타내었으며 뿌리로부터 흡수된 농약의 양은 초기 처리된 절대량의 1.0~1.3% 수준이었다. 대부분은 뿌리에서 가장 많았으며 다음 줄기와 잎 순이었다. 반면에 수확된 오이열매에서 LOQ (0.02 mg/kg) 미만으로 안전한 수준이었으며 부위별 시료 분석결과, 실내시험에서의 결과와 마찬가지로 대부분의 잔류량이 검출되었다. 실외시험에서 한 개체에 chlorpyrifos는 토양에 살포된 양의 0.03~0.04%로 흡수율에 비해 30배 낮은 따라서 실제 토양환경 잔류수준은 본 시험에서 시험된 고농도(40 처리구보다 수준이므로 농산물의 생산이 가능하다고 할 수...
The inhibition of nitric oxide (NO) and cyclooxygenase-2 (COX-2) production is considered to be a promising approach the treatment various diseases, including inflammation cancer. In this study, we examined effects Agrocybe chaxingu beta-glucan (polysaccharide) on lipopolysaccaride (LPS)-induced expression in murine macrophage Raw 264.7 cells as well 12-O-tetradecanoylphorbol 13-acetate (TPA)-induced ear edema mice. polysaccharide significantly inhibited (P 0.01) LPS-induced iNOS COX-2...
The effects of deltamethrin at acute and sublethal concentrations on some hematological biochemical profiles in the Indian major carp Labeo rohita have been examined. lethal (LC50) for 24 96 h were found to be 0.44 0.38 mg L−1, respectively. During treatment (24 h), hemoglobin (Hb), hematocrit (Hct), red blood cell (RBC), white (WBC), mean cellular volume (MCV), (MCH), concentration (MCHC) values significantly increased compared control group. Plasma glucose, protein, cholesterol, albumin,...
