Several lines of evidence suggest that mutation events may be involved in the development of atherosclerosis. The aim of the present investigation was to perform an allelotype analysis in 30 atherosclerotic lesions in order to reveal any deletions involved in the development of the disease. Eighteen chromosomal arms were tested by one microsatellite marker(More)
The aetiopathology of atherosclerosis remains obscure. Although histologically the accumulation of lipids and the proliferation of the smooth muscle cells represents the main feature of the disease, little is known as regards the molecular alterations associated with the atherosclerotic lesions. In the present study we investigated whether an elevated(More)
The levels of expression and the incidence of codon 12 point mutations of the ras family genes were studied in 18 cases of leukemia, seven with acute myeloblastic leukemia (AML), three with acute lymphoblastic leukemia (ALL), four cases with chronic myelogenic leukemia (CML) and four cases with chronic lymphocytic leukemia (CLL). Elevated expression of the(More)
Hepatitis B virus (HBV) infection is considered as one of the major risk factors in the development of human hepatocellular carcinoma (HCC). Recent studies have also suggested the implication of oncogene and onco-suppressor genes in liver carcinogenesis. We studied 41 cases of HCC for the presence of HBV DNA and point mutations in codon 12 of K-ras and(More)
Pterygium is a chronic disease of unknown origin and pathogenesis. It is a vision threatening disease where surgical excision is effective. We examined surgically excised symptomatic pterygia for the presence of herpesviruses such as cytomegalovirus (CMV), herpes simplex virus (HSV) and Epstein-Barr virus (EBV) DNA using the polymerase chain reaction (PCR)(More)
Clinical observations and epidemiological studies on genital cancer have revealed an association with sexual behavior, thus motivating research into sexually transmitted agents which may be responsible for the neoplasia. In this study, we used the PCR technique to examine the presence of CMV, HSV and EBV viruses in 187 cases of human genital lesions and(More)
The purpose of our study was to assess the prevalence and prognostic significance of HPV infection as well as K-ras codon 12 point mutations in lung cancer. Patients diagnosed with lung carcinoma between 1988 and 1992 (N=99) were selected. HPV detection and typing was performed by PCR from paraffin-embedded tissues, while mutations in codon 12 of K-ras gene(More)
DNA extracted from the blood of immunosuppressed and immunocompromised individuals and from patients with infectious mononucleosis, leukaemias and lymphomas were studied using the Polymerase Chain Reaction (PCR) technique. The oligonucleotide primers used for the detection of the Epstein-Barr virus (EBV) amplify a 375bp sequence from the EcoRI B fragment of(More)
Infections caused by Human Cytomegalovirus (HCMV) are very common in patients who undergo immunosuppression or immunocompromisation. The techniques used for routine HCMV detection are time-consuming and lack specificity and sensitivity. The ability of the Polymerase Chain Reaction (PCR) to amplify HCMV DNA from clinical samples of the patients is a valuable(More)
Infections caused by Human Cytomegalovirus (HCMV) and Epstein-Barr virus (EBV) are common in multiple transfused patients, such as patients with beta-thalassaemia. The ability of the Polymerase Chain Reaction (PCR) to amplify HCMV and EBV DNA from blood and other samples makes this technique a valuable diagnostic tool for the detection of both viruses in(More)
