AIM To evaluate whether increased telomerase activity can be clinically useful for detecting malignant cells in a variety of gynaecological specimens. METHODS Telomerase activity was examined in frozen tissue samples of histologically confirmed lesions of the endometrium, ovary, and cervix. It was also assessed in exfoliated cells in cervical smears from patients with premalignant and maligna...

background and objectives: nodular lesions of liver are usually neoplastic (primary or metastatic), although inflammatory lesions can occur. the objectives of this paper were to study the cytomorphological changes in various nodular lesions of liver and to correlate the cytomorphological findings with biochemical parameters especially serum alpha-fetoprotein. materials & methods:  a cross-...

Little is known about the immunoediting process in precancerous lesions. We explored this aspect of benign colorectal adenomas with a descriptive analysis of the immune pathways and immune cells whose regulation is linked to the morphology and size of these lesions. Two series of polypoid and nonpolypoid colorectal adenomas were used in this study: 1) 84 samples (42 lesions, each with matched s...

BACKGROUND/AIMS Esophageal squamous cell carcinoma is a common malignant tumor in recent years, and the key for improving the survival rate is early diagnosis and treatment. Computed virtual chromoendoscopy with the Fujinon intelligent color enhancement (FICE) system was reported to improve visualization of neoplastic and non-neoplastic lesions in gastroscopy and colonoscopy. The purpose of thi...

BACKGROUND: Ovine pulmonary adenocarcinoma (OPA) is a worldwide contagious bronchioalveolar carcinoma caused by infection of a beta retrovirus in sheep and less in goat. Neoplastic proliferation of type II pneumocytes and clara cells, produce papillary to acinar tumoral pattern with infiltration of macrophages, lymphocytes and plasma cells and interstitial fibrosis tissue. OBJECTIVES: This stud...
