Comparison and Analysis of QTLs, Epistatic Effects and QTLx Environment Interactions for Yield Traits Using DH and RILs Populations in Rice

Journal of Integrative Agriculture 2013年第2期12卷 198-208页

作者： ZHAO Xin-hua QIN Yang JIA Bao-yan Suk-man Kim Hyun-Suk Lee Moo-Young Eun Kyung-Min Kim jae-Keun Sohn Department of Agronomy Shenyang Agricultural University School of Applied Biosciences College of Agriculture & Life Science Kyungpook National University Bio Safety Division Department of Agricultural Biotechnology National Academy of Agricultural Sciences Rural Development Administration C/O IRRI-Korea office National Institute of Crop Science Rural Development Administration

Two genetic linkage maps, constructed by DH and RILs populations derived from the same parents, were carried out for the identification and comparison of QTLs controlling yield traits across different years in rice （Oryza sativa L.）. A total of 194 SSR and STS markers were used in two maps, of which 114 markers were same. The distribution of Samgang allele was higher in RILs population than it in DH population. Comparing with DH population, RILs population has more lines with higher yield and wider phenotypic transgressive segression for yield traits. Although most of QTLs for the same trait were different in two populations across different years, 8 QTLs （including gwp 11.1, spp5.1, spp 10.1, spp 11.2, ssrl. 1, ssrl 1.1, tgw9.1 and tgwl 1.1） were detected over 2 yr. It is important to note that pppl0.1, sppl0.1 and tgw9.1 were identified in two populations, while sppl 0.1 and tgw9.1 were simultaneity observed across different years. Epistatic effects were more important than additive effects for PPP, SPP, yield in DH population and TGW, yield in R/Ls population. Epistatic effects of DH and RILs populations were different on the same genetic background in the present study, which illuminated the QE interaction played an important role on epistatic effect. Identification and comparison of QTLs for yield traits in DH and RILs populations should provide various and more precise information. The QTLs identified in present study would be valuable in marker-assisted selection program for improving rice yield.

Quality of Life (QOL) in Long-Term Survivors of Osteosarcoma

引用

Journal of Cancer Therapy 2013年第1期4卷 133-137页

作者： jae Do Kim jae man Kwak So Hak Chung Department of Orthopedic Surgery Kosin University Gospel Hospital Busan Korea.

We conducted this study to analyze the quality of life using the SF-36 health questionnaire and the MSTS scores depending on surgical method and the primary site of occurrence. On the surgical method, the limb salvage had more excellent outcomes (60.9) than the amputation (46.3). The tumor prosthetic replacement had notably higher scores (62.5) than any other methods. For the correlation coefficients on the MSTS and SF-36, the Physical Function had the highest degree of correlation. Excellent functions of the extremities would lead to a good quality of life.

BACKGROUND It is usually difficult to adequately conduct percutaneous ultrasound-guided radiofrequency(RF) ablation for hepatocellular carcinomas(HCCs) abutting the diaphragm. Our hypothesis was that the subphrenic location of HCC could have an effect on the long-term therapeutic outcomes after hepatic resection and RF *** To compare the long-term therapeutic outcomes of hepatic resection and percutaneous RF ablation for HCCs abutting the *** A total of 143 Child-Pugh class A patients who had undergone hepatic resection(n = 80) or percutaneous ultrasound-guided RF ablation(n = 63) for an HCC(≤ 3 cm) abutting the right diaphragm were included. Cumulative local tumor progression(LTP), cumulative intrahepatic distant recurrence(IDR), disease-free survival(DFS), and overall survival(OS) rates were estimated. Prognostic factors for DFS and OS were analyzed. Complications were *** The cumulative IDR rate, DFS rate, and OS rate for the hepatic resection group and RF ablation group at 5 years were "35.9% vs 65.8%", "64.1% vs 18.3%", and"88.4% vs 68.7%", respectively. Hepatic resection was an independent prognostic factor for DFS(P ≤ 0.001; hazard ratio, 0.352; 95%CI: 0.205, 0.605; with RF ablation as the reference category); however, treatment modality was not an independent prognostic factor for OS. The LTP rate was 46.6% at 5 years for the RF ablation group. The major complication rate was not significantly different between the groups(P = 0.630). The rate of occurrence of peritoneal seeding was higher in the RF ablation group(1.3% vs 9.5%, P = 0.044).CONCLUSION Although OS was not significantly different between patients who had gone hepatic resection or percutaneous RF ablation for HCCs abutting the diaphragm,DFS was better in the hepatic resection group.

Inverted cystic tubulovillous adenoma involving Brunner’s glands of duodenum

引用

World Journal of Gastroenterology 2007年第23期13卷 3262-3264页

作者： Ji Hoon Kim Jung Woo Choi Yeon Seok Seo Beom jae Lee Jong Eun Yeon jae Seon Kim Kwan Soo Byun Young-Tae Bak Insun Kim Jong- jae Park Division of Gastroenterology Department of Internal Medicine Korea University College of Medicine Seoul South Korea Department of Pathology Korea University College of Medicine Seoul South Korea

Benign neoplasia of the duodenum are very rare. Moreover, duodenal tubulovillous adenomas are more uncommon lesions. The microscopic structure of tubulovillous adenoma has frond-like projection of mucosa with branching papillary structure and generally upward growth into the lumen. We describe a 72-year-old man who showed aduodenal tubulovillous adenoma with unusual inverted cystic growth pattern. Interestingly, this tubulovillous adenomatous lesion was interrupted by gastric metaplasia in the deep portion of the cyst and was closely surrounded by Brunner’s glands. Although histogenesis of gastric metaplasia of duodenum is not fully understood, Brunner’s glands has been suggested as a precursor for gastric metaplasia. Therefore, these findings argued that this adenoma arises from Brunner’s glands through gastric metaplasia. This is the first case of inverted cystic tubulovillous adenoma involving Brunner’s glands of duodenum with gastric metaplasia.
