of the C3G on day 1 and 14. There was no observed accumulation of C3G after 2-week multiple dosing of black bean seed coat extract. The typical point estimates of PK were CL (clearance)=3,420 l/h, V (volume)=7,280 L, Ka (absorption constant)=9.94 h－1, ALAG (lag time)=0.217 h. The black bean seed coat extract was well tolerated and there were no serious adverse events. In this study, we confirmed that a significant amount of C3G was absorbed in human after given the black bean seed coat extract. -

Brucella abortus is a bacterium that causes brucellosis and is the causative agent of worldwide zoonoses. Pathogenesis of the B. abortus infection is complicated, and several researchers have attempted to elucidate the infection mechanism of B. abortus. While several proteins have been revealed as pathogenic factors by previous researchers, the underlying mechanism of B. abortus infection is unresolved. In this study, we identified proteins showing different expression levels in B. abortus... -

대한수의학회 Journal of Veterinary Science 2014, 제 15권 제 1호 1 1-17 (17 pages)
Calf diarrhea is a commonly reported disease in young animals, and still a major cause of productivity and economic loss to cattle producers worldwide. In the report of the 2007 National Animal Health Monitoring System for U.S. dairy, half of the deaths among unweaned calves was attributed to diarrhea. Multiple pathogens are known or postulated to cause or contribute to calf diarrhea development. Other factors including both the environment and management practices influence disease severity or... -

(r = -0.23, P > 0.05) and FHB incidence (r = 0.19, P > 0.05) in the artificially inoculated nursery with grain spawn method. FHB severity, DON concentration, and yield were affected by year, genotype, and the genotype × year interaction. The effectiveness of green- house spray inoculation for indirect selection for low DON concentration requires further studies. Nine of the 48 genotypes were found to contain low DON under natural infection. Island barley had low DON and also had high yield. -

Plant immune responses can be triggered by chemicals, microbes, pathogens, insects, or abiotic stresses. In particular, induced systemic resistance (ISR) refers to the activation of the immune system due to a plant’s in- teraction with beneficial microorganisms. The phenolic compound, 2,4-diacetylphloroglucinol (DAPG), which is produced by beneficial Pseudomonas spp., acts as an ISR elicitor, yet DAPG’s mechanism in ISR remains unclear. In this study, transgenic Arabidopsis thaliana plants... -

Winter wheat is susceptible to several fungal pathogens throughout the growing season and foliar fungicide application is one of the strategies used in the management of fungal diseases in winter wheat. However, for fungicides to be profitable, weather conditions conducive to fungal disease development should be present. To determine if winter wheat yield response to fungicide application at the flowering growth stage (Feekes 10.5.1) was related to the growing season precipitation, grain yield... -

formed during the evolutionary history of M. oryzae. Synteny analyses using closely related fungal species corroborated the notion that these genes evolved de novo in the M. oryzae genome. In this report, we discuss our inability to detect phenotypic changes in the four deletion mutants. Based on these results, the four orphan genes may be products of de novo gene birth processes, and their adaptive potential is in the course of being tested for retention or extinction through natural selection. -

of clip-dipping inoculation and FHB Type II resistance from adult plants were significant (r=0.45; P<0.05). Results from two other seedling inoculation methods, spraying and pin-point inoculation, were not correlated with adult FHB resistance. Single linear correlation was not significant between seed germination assays (soaking and soak-dry) and FHB resistance (Type I and Type II), respectively. These results showed that clip-dipping inoculation method using F. graminearum may offer a... -

산업화 초반에는 세습보다는 교육이 지위이동의 사다리 역할을 담당하였으나 이제는 직접 상속, 소 득양극화, 사교육의 활용, 거주지 분화, 계층에 따른 학교 서열화 등 다양한 방식으로 출발점에서의 불평등이 일어나고 있다는 연구가 증가하고 있다. 이는 메리토크라시의 기저에 놓여있는 원리와 그 신화에 대해 다시금 생각해보도록 한다. 이에 대한 논의를 위해 이 논문은 메리토크라시 용어를 처음 창안한 Michael Young의 『메리토크라시의 발흥』으로 다시 돌아가, 그 체제의 특징과 한계를 살펴본 다음 그것의 현재적 의미에 대해... -

본 연구에서는 강우관측소의 고도별 공간분포의 적정성을 평가하기 위한 방안으로 고도별 강우관측소의 최근린지수를 산정하고, 현재 강우관측소 공간분포의 적정성을 평가하였다. 등면적비를 이용하여 고도를 구분하고, 고도마다 다른 지형적인 조건을 고려하기 위하여 주어진 지형조건내에서 가능한 최대 NNI을 최적화 기법의 하나인 화음탐색법을 이용하여 산정하였다. 이와 같이 고도별로 현재 상태 및 최대 NNI를 산정한 후 이 두 값의 차이를 바탕으로 고도별로 강우관측소 분포를 평가하였다. 그 결과 고도가 높아질수록...
