The aim of this study was to analyze the prevalence of BK virus, Human Papillomavirus and Epstein-Barr virus in oropharyngeal cancer, and to test our hypothesis that BKV/HPV/EBV co-infection plays a role in oropharyngeal squamous cell carcinoma. The correlation between viral infection, OSCC, anatomic location, pre-treatment staging, evidence of metastases to lymph nodes, and grading was also investigated...
Head and neck cancers constitute the sixth most common malignant tumours worldwide, and are one of the majors problems of global public health. In the oral cavity there are several types of oral cancers, but around 90% are squamous cell carcinoma. Many different risk factors play a role in the etiology of head and neck cancer. The aim of this study is presentation from the aspect of molecular, viral...
The aim of this study was to compare the prevalence of EBV genotype and del-LMP-1 in saliva from Polish, Taiwanese and Arabic healthy students. The study group consisted of 56 healthy students; 24 of them Polish, 25 Taiwanese, and 7 Arabic. Typing was carried out using PCR with EBNA-2 primers. A detection of LMP-1 variants was also performed using PCR. EBV DNA was detected in 22 investigated samples...
The aim of this study was the analysis of the prevalence of Herpesviridae (EBV, CMV, HSV-1) among patients with head and neck cancers (larynx and hypopharynx squamous cell carcinoma). Correlation between viral infection, HNSCC, alcohol use, tobacco smoking, demographic data (gender, age, place of residence, occupation), anatomic location, pre-treatment staging, evidence of metastases to lymph nodes,...
The aim of this study was to analyse the prevalence of human papillomavirus (HPV) infection among patients with oral and oropharynx squamous cell carcinoma (OSCC). The correlation between HPV infection and OSCC, HPV genotypes, and correlation between HPV, OSCC, alcohol use, tobacco smoking, demographic data (gender, age, place of residence), anatomic location, pretreatment staging, metastases of lymph...
In this paper we discuss a new architecture to reduce unsolicited e-mail messages. We propose a system architecture that introduces two classes of messages-trusted e-mail and e-mail from untrusted sources. Trusted e-mail messages are signed with an S/MIME signature. To address usability problems that occurred previously with S/MIME signatures, outgoing e-mail messages are automatically signed on the...
