Bacterial infection may adversely affect the hemostasis of patients with gastroesophageal variceal bleeding (GEVB). Antibiotic prophylaxis can prevent bacterial infection in such patients, but its role in preventing rebleeding is unclear. Over a 25-month period, patients with acute GEVB but without evidence of bacterial infection were randomized to receive prophylactic antibiotics (ofloxacin 20...

Combination therapy of pegylated interferonwith ribavirin (PEG-IFN/RBV) is a standard of care for chronic hepatitis C (CHC). The majority of CHC patients are infected with HCV genotype I. The recent discovery revealed by a genome-wide association study technology provides the important role of interleukin-28B (IL28B) and inosine triphosphatase (ITPA) in HCV infection. In addition, response to P...

In-vivo dynamic visualization and accurate quantification of vascular networks is a prerequisite of crucial importance in both therapeutic angiogenesis and tumor anti-angiogenesis studies. A user independent computerized tool was developed, for the automated segmentation and quantitative assessment of in-vivo acquired DSA images. Automatic vessel assessment was performed employing the concept o...

With the advent of WWW, there is considerable interest in programs that can migrate from one host to another and execute. For instance, Java programs are increasingly being used to add dynamic content to a web page. When a user accesses the web page through a browser, the browser migrates the Java program and executes it at the user’s site. Mobile programs are appealing because they support eff...

Current trends demonstrate an increasing use of polymorphism by attackers to disguise their exploits. The ability for malicious code to be easily, and automatically, transformed into semantically equivalent variants frustrates attempts to construct simple, easily verifiable representations for use in security sensors. In this paper, we present a quantitative analysis of the strengths and limita...

This paper presents some of the results from the Commission of the European Communities collaborative research program (contract number EV5V-CT92-0221), whose aim is to investigate the relationship between exposure to petroleum emissions, benzene, and induction of genetic damage in human cells. Twenty-four workers from petroleum plants in Poland and 35 unexposed controls were examined for cytog...

Hepatocellular carcinoma (HCC), one of the most common cancers worldwide, is particularly prevalent in the Asia-Pacific region. Guidelines on the treatment of HCC in Japan come from both consensus-based and evidence-based treatment algorithms. However, patients with extensive liver damage and/or more advanced disease (major vascular invasion and/ or extrahepatic spread) are currently ineligible...
