Sensitivity, specificity and correlations among several biomarkers for monitoring occupational exposure to complex mixtures of genotoxic agents were assessed in occupational environments in Hungarian study populations. The studies have been focused on DNA adduct formation, urinary metabolites, mutations and micronuclei induced by exposures to complex(More)
A subunit vaccine in the form of immunostimulating complex (iscom) was prepared to contain the envelope glycoproteins of bovine herpesvirus type 1 (BHV-1). This iscom preparation was tested in a vaccination experiment on 4-month-old calves seronegative to BHV-1. In this experiment, four groups with three animals per group were used. Two groups were(More)
BACKGROUND Preoperative radio-chemotherapy (RCX) was introduced to improve the outcome of patients with oesophageal cancer (EC), but conflicting results have been released. Some 20-30% of patients show a complete pathological response, however, the perioperative morbidity and mortality is increased. To search for factors indicating response prior to the(More)
BACKGROUNDS/AIMS The present study was designed to provide an analysis of factors for tumor vascularisation and proliferation in 37 rectal cancer patients with concurrent and recurrent liver metastasis underwent preoperative radiotherapy, surgery and adjuvant chemotherapy with emphasis on the time of presence of hepatic spread.

We analyzed a teaching institution's experience with intra-operative cholangiography (IOCG) and endoscopic retrograde cholangiopancreatography (ERCP) and established an algorithm for their timing and use. The records of all patients undergoing LC during a five year period were reviewed. Patients with a history of jaundice or pancreatitis, abnormal(More)
BACKGROUND/AIMS Gastrointestinal stromal tumors (GIST) are the most frequent non-epithelial tumors of the alimentary tract. The interstitial cells of Cajal or more primitive progenitor mesenchymal cells are suggested as their cells of origin. GIST's occur throughout the gastrointestinal tract but are generally located in the stomach and the intestine. About(More)
The etiological role of human papillomavirus (HPV) in a number of squamous malignant tumors is well known. Squamous cell carcinoma (SCC) of colon is a rare disease with uncertain etiology. Our objective was to detect possible HPV infection in a colon SCC patient. The 94-year-old female patient was operated due to colon tumor causing passage disturbances.(More)
BACKGROUND/AIMS Human papilloma virus (HPV) infection in esophageal cancer cases has been found in 0-70%, depending on different methods and geographical variances. Complete pathological response has been found in 30% of cases after neoadjuvant chemo-radiation (CRX). The aim of this study was to discover a possible relation between HPV-infection and(More)
Pancreatic Intraepithelial Neoplasia (PanIN1-3) and Intraductal Papillary Mucinous Neoplasms (IPMN) putative precursors of and associated to pancreatic cancer represent a distinct, however pathologically heterogenous entity. Recently a new classification and nomenclature was established. We review the clinicopathologic and cytogenetic characteristics of(More)
