Security remains a major roadblock to universal acceptance of the Web for many kinds of transactions, especially since the recent sharp increase in remotely exploitable vulnerabilities have been attributed to Web application bugs. Many verification tools are discovering previously unknown vulnerabilities in legacy C programs, raising hopes that the same(More)
As a large and complex application platform, the World Wide Web is capable of delivering a broad range of sophisticated applications. However, many Web applications go through rapid development phases with extremely short turnaround time, making it difficult to eliminate vulnerabilities. Here we analyze the design of Web application security assessment(More)
To study the etiologic factors of non-familial breast cancer, the polymerase chain reaction (PCR) and Southern hybridization were used to detect six viruses including human papillomavirus (HPV), cytomegalovirus (CMV), Epstein-Barr virus (EBV), herpes simplex virus (HSV)-1, HSV-2, and human herpesvirus (HHV)-8 DNA in 69 patients with breast cancer and 60(More)
Heat shock protein 70 (HSP70) is an important stress-induced protein. Areca quid chewing is a major risk factor of oral squamous cell carcinoma (OSCC). The aim of this study was to compare HSP70 expression in normal human oral epithelium and OSCC and further to explore the potential mechanisms that may lead to induce HSP70 expression. 41 OSCC and 10 normal(More)
BACKGROUND The association between oral squamous cell carcinoma (OSCC) and viral and chemical factors is uncertain. Therefore the correlation of viral and chemical factors with oral cancer in Taiwan was investigated. METHODS Thirty-seven paraffin-embedded oral cancer biopsies and 36 normal oral tissue specimens were examined by the polymerase chain(More)
In order to search for new thermophilic microorganisms and their enzymes, bacterial strains from black liquor of brownstock at washing stage of kraft pulping process were screened. Therein a multiple glycosyl hydrolase-producing strain, BL11, was isolated as a dominant species in the xylan-degrading bacterial population and identified as Paenibacillus(More)
Metallothioneins (MTs) are a family of low molecular weight, cysteine-rich, inducible, intracellular proteins that bind heavy metals with high affinity. MT-1 is known as a stress-inducible protein and functions as an antioxidant enzyme. Areca quid chewing is a major risk factor in the development and further progression of oral squamous cell carcinoma(More)
Chronic subcutaneous (s.c.) administration of d-galactose (DG) to BL/6J mice has been shown to induce oxidative stress and is considered a model to mimic accelerated ageing. Fructo-oligosaccharide (FO) is a well-defined prebiotic and its fermentation by lactic acid bacteria has been shown to exert antioxidative capacity. The present study was aimed to(More)
Platelet-rich fibrin (PRF) by Choukroun's technique is produced in a totally natural manner, without using anticoagulant during blood harvest nor bovine thrombin and calcium chloride for platelet activation and fibrin polymerization. When delicately pressed between two gauzes, the PRF clot becomes a strong membrane with high potential in clinical(More)
