The estimation of 90% parametric confidence intervals (CIs) of mean AUC and Cmax ratios in bioequivalence (BE) tests are based upon the assumption that formulation effects in log-transformed data are normally distributed. To compare the parametric CIs with those obtained from nonparametric methods we performed repeated estimation of bootstrap-resampled datasets. The AUC and Cmax values from 3 archived datasets were used. BE tests on 1,000 resampled datasets from each archived dataset were... -

were used for this analysis. The asserted cognitive model of this study identified that there were two casual conditions, (a) authoring goal and (b) authoring tool. The conditions resulted in chunking strategy and top-down approach to select sub-concepts. During the transformation process, the authoring tool used in this study was regulating of selecting and linking concepts. Findings were discussed in terms of how the asserted cognitive model would affect knowledge transformation process. -

한국식물병리학회 The Plant Pathology Journal 2014, 30권 3호 10 310-315 (6 pages)
efficient evaluation of resistance to TYLCV. Here, we present the rolling circle amplification (RCA) method, which employs a bacteriophage using phi-29 DNA polymerase for construction of infectious TYLCV clones. The RCA method is simple, does not require sequence information for cloning, and is less expensive and time consuming than conventional PCR based-methods. Furthermore, RCA-based construction of an infectious clone can be very useful to other emerging and unknown geminiviruses in Korea. -

of a "gold standard" method. Different methods have often been used interchangeably or cited as being comparable in the existing literature; however, the actual agreement between assays has not been investigated. Therefore, in this study, we evaluated the level of agreement between three different assays using equine plasma obtained from 29 horses. Two spectrophotometric assays using Furylacryloyl- phenylalanyl-glycyl-glycine as substrate and one fluorimetric assay utilizing o-aminobenzoic... -

Most known osteoporosis medicines are effective for bone resorption, and so there is an increasing demand for medicines that stimulate bone formation. Watercress (N. officinale R. Br.) is widely used as a salad green and herbal remedy. This study analyzed a watercress extract using ultra-performance liquid chromatography/mass spectrometry, and identified a rutin as one of its major constituents. Osteogenic-related assays were used to compare the effects of watercress containing rutin (WCR) and... -

대한생리학회-대한약리학회 The Korean Journal of Physiology & Pharmacology 2007, Vol.11 No.2 5 71-77 (7 pages)
Cisplatin treatment increases the excretion of inorganic phosphate in vivo. However, the mechanism by which cisplatin reduces phosphate uptake through renal proximal tubular cells has not yet been elucidated. We examined the effect of cisplatin on Na-dependent phosphate uptake in opossum kidney (OK) cells, an established proximal tubular cell line. Cells were exposed to cisplatin for an appropriate time period and phosphate uptake was measured using [32P]-phosphate. Changes in the number... -

Pseudomonas cichorii secretes effectors that suppress defense mechanisms in host plants. However, the function of these effectors, including avirulence protein E1 (AvrE1), in the pathogenicity of P. cichorii, remains unexplored. In this study, to investigate the function of avrE1 in P. cichorii JBC1 (PcJBC1), we created an avrE1-deficient mutant (JBC1ΔavrE1) using CRISPR/ Cas9. The disease severity caused by JBC1ΔavrE1 in tomato plants significantly decreased by reducing water soaking during... -

한국식물병리학회 The Plant Pathology Journal 2014, 30권 4호 13 440-444 (5 pages)
Iris yellow spot virus (IYSV) is a plant pathogenic virus which has been reported to continuously occur in onion bulbs, allium field crops, seed crops, lisianthus, and irises. In South Korea, IYSV is a “controlled” virus that has not been reported, and inspection is performed when crops of the genus Iris are imported into South Korea. In this study, reverse-transcription polymerase chain reaction (RT-PCR) and nested PCR inspection methods, which can detect IYSV, from imported crops of the... -

헤파린이 1941년 Hedenius에 의해 처음 소개된 이후 급성 기 색전성 뇌졸중의 재발 감소에 효과가 있다는 연구도 있지만, 메타분석에서 인정받지는 못했고(Paciaroni, Agnelli, Micheli, & Caso, 2007), 진행성 뇌졸중의 경우에도 효과가 입 증되지는 않았다(Roden-Jullig & Britton, 2000). 이에 따라 허혈성 뇌졸중의 치료에 정맥주사 헤파린의 사용이 감소하였 는데, 1988년부터 2001년까지 북미의 신경과 전문의를 대상 으로 한 연구에서 색전증을 제외한 모든 유형의 뇌졸중에서 정맥주사 헤파린의 사용의도가 종전에 비해 감소한... -

구조화 이론에 따르면 구조와 행위자는 상호의존적 관계 안에 존재하며, 이 구조들은 인간의 행동을 제약하기도 하고 촉진하기도 한다. 구조화 이론을 건강 불평등 문제에 접목시켰을 때, 우리는 커뮤니케이션 인프라가 국가적 보건 측면에서 제약적인, 그리고 촉진적인 역할을 수행할 것임을 추정해 볼 수 있다. 본 연구는 국가의 정보통신망이 유아, 아동 사망률에 미치는 장기적 영향을 측정하기 위해 인구 천 명당 전화회선의 평균 숫자를 변수로 사용했다. 세계개발 지수를 이용해 202개 국가를 대상으로 종단적 회귀분석을 적용해... -

One of the most acute problems in studying composite stress-strain states is determining the initial residual stresses during the design of layered construction elements. The full stress?strain state of composite constructions consists of the initial (generated during the manufacturing process) and operating (generated during the working period) stages. A thorough investigation of the initial stage of the stress-strain state is very important to finding the total stresses and deformations, and...
