Cardiotoxicity in rabbits after a low-level exposure to diazinon, propoxur, and chlorpyrifos.

Lethal cardiac complications leading to death and various arrhythmias have been reported after organophosphate and/or carbamate poisonings. The present study focuses on the long-term effects of repeated low-level exposure to diazinon, propoxur, and chlorpyrifos (CPF) on cardiac function in rabbits. The yearly based experimental scheme of exposure consisted of two oral administration periods, lasting 3 months and 1 month each, interrupted by an 8-month washout period (total duration 12 months).

Evaluation of the prevalence of human papillomavirus and Epstein-Barr virus in esophageal squamous cell carcinomas.

The aim of this study was to determine the possible involvement of human papillomavirus and Epstein-Barr virus in esophageal squamous cell cancer (ESCC) carcinogenesis in the Greek population. DNA was extracted from 30 ESCC and 27 normal esophageal specimens and screened for HPV type-specific or EBV infection by PCR-based assay. Seventeen out of 30 ESCC specimens (56%) were found positive for HPV DNA, of which 15 (88%) were typed as HPV-18 infected, one (5.

Malignant peritoneal mesothelioma presenting with respiratory symptoms.

Malignant peritoneal mesothelioma is a rare disease associated with mild, nonspecific abdominal symptoms and a wide spectrum of imaging findings, with thickened mesentery and peritoneum being the most common ones. A case of a malignant peritoneal mesothelioma presenting with manifestations of pulmonary disease is reported. Imaging evaluation revealed pleural, lung and pericardial involvement together with retroperitoneal lymphadenopathy, little ascites and extensive omental, but only subtle, mesenteric thickening.

Primary thyroid non-Hodgkin's lymphomas: clinicopathological observations on patients living in the island of Crete.

Fifteen patients with primary thyroid non-Hodgkin's lymphomas (PT-NHLs) living in the island of Crete were studied. Patients' median age was 69 years, male/female ratio 1.5/1 and stage I/stage II ratio 2/1 (stages III and IV were excluded).
