Hemobilia occurs when injury or disease causes communication between intrahepatic blood vessels and the intrahepatic or extrahepatic biliary system. The causes of hemobilia include trauma, gallstone disease, vascular malformation, inflammation, and biliary or hepatic tumors. Hemobilia could be diagnosed by endoscopy, hepatic angiography, computed tomography, and ultrasonogram. Patients with hemobilia may present with biliary colic, obstructive jaundice and gastrointestinal bleeding. Extrahepatic cholangiocarcinoma usually presents with obstructive jaundice and is one of the unusual cause of hemobilia. We, herein, report a case of hemobilia caused by cholangiocarcinoma in a 69-year-old woman. She had the past history of lung cancer and choledochoduodenostomy due to gallstone. Esophagogastroduodenoscopy revealed a blood clot protruding from the choledochoduodenostomy site and the ulcerative mass in the common bile duct. Pathologic examination of the ulcerative mass was compatible with those of cholangiocarcinoma. (Korean J Gastroenterol 2010;56:205-208)

<P>Blackberry is a fruiting berry species with very high nutrient contents. With the recent increasing consumer demand for blackberries, new sources of germplasm and breeding techniques are required to improve blackberry production. This study was carried out to evaluate the genetic diversity (GD) and relationship among 55 blackberry (<I>Rubus fruticosus</I>) mutants derived from γ-ray treatment (52 lines) and <I>N</I>-methyl-<I>N</I>′-nitrosourea (MNU) treatment (three lines) using an inter-simple sequence repeat marker. A total of 18 bands were amplified with an average of 3.6 bands per primer. Among them, eight bands were identified to be polymorphic with a rate of 44.4%. In addition, the GD information content values were highest in the 60 Gy treatment population and the GD values were higher in the γ-ray treatment populations than in the MNU treatment population. According to a cluster analysis, all the mutant lines can be classified into five categories, and the genetic distance was greatest between the 80 Gy-irradiated population and other populations. These results indicate that mutant lines have high GD and can be effectively utilized for improving blackberry breeding.</P>

The Rubus fruit is an economically important berry crop that contains various functional compounds. The objective of this study was to analyze fruit qualities (i.e., pH, soluble solids content, titratable acidity, and mineral content) as well as fatty acid and phenolic compounds (i.e., ellagic acid and anthocyanins) among hybrid boysenberry lines developed by hybridization and gamma irradiation. There were no significant differences in the hybrid boysenberry fruit pH and titratable acidity (%) among the tested genotypes. However, the soluble solids content was higher in the BSA119 and BSA144 mutants than in the original genotype (BS_Hybrid). Meanwhile, linoleic acid was the most abundant fatty acid in the analyzed hybrid boysenberry fruits. The fatty acid composition did not differ significantly among the genotypes. The ellagic acid content of all genotypes ranged from 8.72 mg/100 g to 46.10 mg/100 g, with the highest concentration observed for the BSB127 genotype. Additionally, cyanidin-3-O-sophoroside (M-H<sup>+</sup>, 611 m/z) and cyanidin-3-O-glucoside (M-H<sup>+</sup>, 449 m/z) were the two major anthocyanins detected in the boysenberry and mutant genotypes, while cyanidin-3-O-glucoside was the predominant blackberry anthocyanin. The total anthocyanin concentrations of four mutant genotypes (i.e., BSA036, BSA078, BSA101, and BSB127) were significantly higher than that of the original genotype (382.0 mg/100 g). The highest total anthocyanin concentration was observed for the BSA078 genotype (467.9 mg/100 g). These results may be useful for identifying the optimal genotypes for breeding new cultivars with enhanced qualities and potential health benefits.

This study shows the path algorithm developed for an UGV (Unmanned Ground Vehicle). The UGV frame which has a 4-Wheel-driven mechanism and diesel source was used in this study. The actuators as control inputs of the UGV are a steering wheel actuator, an acceleration-breaking actuator. The optima! controller was used for the path tracking algorithm using the nonlinear kinematics modeling of the UGV. The path algorithm shows the availability as applying the path algorithm to the real UGV.
