Two giant pandas (Ailuropoda melanoleuca) died of unknown causes in a Chinese zoo. The clinical disease profile suggested that the pandas may have suffered a viral infection. Therefore, a series of detection including virus isolation, electron microscopy, cytobiological assay, serum neutralization and RT-PCR were used to identify the virus. It was determined that the isolated virus was a canine coronavirus (CCV), on the basis of coronavirus, neutralization by canine anti-CCV serum, and 84.3% to... -

In this study, we investigated whether glycyrrhizin, prunetin and morroniside affect mucin secretion from cultured airway epithelial cells and compared the possible activities of these agents with the inhibitory action on mucin secretion by poly-L-lysine (PLL) and the stimulatory action by adenosine triphosphate (ATP). Confluent primary hamster tracheal surface epithelial (HTSE) cells were metabolically radiolabeled using 3H-glucosamine for 24 h and chased for 30 min in the presence of varying... -

대한생리학회-대한약리학회 The Korean Journal of Physiology & Pharmacology 2001, Vol.5 No.2 7 165-175 (11 pages)
Background: Recent in vivo experimental evidence suggests that isoflurane-induced cardioprotection may involve KATP channel activation. However, it was demonstrated that isoflurane inhibited KATP channel activities in the inside-out patch mode. To explain this discrepancy, the present investigation tested the hypothesis that a metabolite of isoflurane, trifluoroacetic acid (TFA), contributes to isoflurnae-induced cardioprotection via KATP channel activation during myocardial ischemia and... -

대한생리학회-대한약리학회 The Korean Journal of Physiology & Pharmacology 2001, Vol.5 No.1 5 33-40 (8 pages)
The aim of present study was to define the cellular mechanisms underlying changes in delayed rectifier K (KDR) channel function in isoproterenol-induced hypertrophy. It has been proposed that KDR channels play a role in regulation of vascular tone by limiting membrane depolarization in arterial smooth muscle cells. The alterations of the properties of coronary KDR channels have not been studied as a possible mechanism for impaired coronary reserve in cardiac hypertrophy. The present... -

of endothelium. EIRF shows positive Griess reaction and is diffusible and quite stable. EIRF-induced relaxation was stronger on PE-contracted aorta than on KCl-contracted one, and inhibited by the pretreatment with methylene blue. Zaprinast, a cGMP-specific phosphodiesterase inhibitor, potentiated the EIRF-induced relaxation. NG-nitro-L-arginine, NO synthase inhibitor, did not inhibit the EIRF-induced relaxation. Deferroxamine, but not ascorbic acid, DMSO potentiated the EIRF-induced relaxation.... -

Pseudomonas syringae pv. tabaci 6605 has two mul- tidrug resistance (MDR) efflux pump transporters, MexAB-OprM and MexEF-OprN. To understand the role of these MDR efflux pumps in virulence, we generated deletion mutants, ∆mexB, ∆mexF, and ∆mexB∆mexF, and investigated their sensitivity to plant-derived antimicrobial compounds, antibiotics, and virulence. Growth inhibition assays with KB soft agar plate showed that growth of the wild-type (WT) was inhibited by 5 μl of 1 M... -

Similarly ethyl acetate extract of TbL-22 showed highest inhibition zones 15.31 ± 2.08 and 19.37 ± 3.17 mm against XccW3 and XccM6, respectively. TbL-22 reduced canker incidence on infected leaves by 64.05% relative to positive controls. Scanning electron microscopy revealed that the cell membranes of Xcc treated with ethyl acetate extract of TbL-22 were ruptured, lysed, and swollen. B. thuringiensis TbL-22 can effectively and sustainably controls streptomycin-resistant citrus canker. -

Sorghum is the fifth most important cereal worldwide, spreading from Africa throughout the world. It is particularly important in the semi-arid tropics due to its drought tolerance, and when cultivated in Southeast Asia commonly occurs as a second crop during the dry season. We recovered Fusarium from sorghum in Thailand and found F. proliferatum, F. thapsinum and F. verticillioides most frequently, and intermittent isolates of F. sacchari and F. beomiforme. The relatively high frequencies of F.... -
Purification and Characterization of a Major Extracellular Chitinase from a Biocontrol Bacterium, Paenibacillus elgii HOA73
한국식물병리학회 The Plant Pathology Journal 11 Pages
한국식물병리학회 The Plant Pathology Journal 2017, 33권 3호 10 318-328 (11 pages)
Chitinase-producing Paenibacillus elgii strain HOA73 has been used to control plant diseases. However, the antimicrobial activity of its extracellular chitinase has not been fully elucidated. The major extracellular chitinase gene (PeChi68) from strain HOA73 was cloned and expressed in Escherichia coli in this study. This gene had an open reading frame of 2,028 bp, encoding a protein of 675 amino acid residues containing a secretion signal peptide, a chitin-binding domain, two fibronectin type... -
Insight Into Genes Involved in the Production of Extracellular Chitinase in a Biocontrol Bacterium Lysobacter enzymogenes C-3
한국식물병리학회 The Plant Pathology Journal 7 Pages
한국식물병리학회 The Plant Pathology Journal 2012, 28권 4호 13 439-445 (7 pages)
The chitinase producing Lysobacter enzymogenes C-3 has previously been shown to suppress plant pathogens in vitro and in the field, but little is known of the regulation of chitinase production, or its role in antimicrobial activity and biocontrol. In this study, we isolated and characterized chitinase-defective mutants by screening the transposon mutants of L. enzymogenes C-3. These mutations disrupted genes involved in diverse functions: glucose-galactose transpoter (gluP), disulfide bond... -

2020년 8월 충청남도 음성지역에서 노지에서 재배중인 질경 이 143 개체 가운데 약 20개체의 잎으로부터 고리형태의 괴사 증상을 포함한 바이러스 유사증상이 나타나는 것을 발견하였 다. 다양한 바이러스 증상을 나타내는 8개체로부터 impatiens necrotic spot virus (INSV), 토마토반점위조바이러스(tomato spotted wilt virus) 및 cucumber mosaic virus가 검출되었으며, 질경이모자이크바이러스(plantago asiatica mosaic virus)는 검출되지 않았다. 질경이로부터 분리한 ‘INSV-plantain kr1’ 분 리주(MW114834)의 L 분절 유전체... -

본 연구는 한국형 온라인 공개강좌(K-MOOC)의 특성과 교육효과에 관한 구조적 관계를 밝혀내고, 지각된 유용편의성과 학습기대의 매개효과를 검증하였다. 분석을 위해 K-MOOC 강좌를 수강한 369명의학습자를 대상으로 조사를 실시하였고, 이 중 여성 은 51.5%(190명), 남성은 48.5%(179명)이고, 이수자는50.1%(185명), 미이수자는 49.9%(184명)이다. 분석결과 K-MOOC의 특성 중에서 교수 실재감이 학습자의지각된 유용편의성에 가장 큰 영향을 미치고 있었으며, 다음으로는 흥미와 신뢰의 순이었다. 지각된 유용편의성은 교육효과에...
