Introduction: Gastric cancers are the second cause of cancer related deaths all around the world but gastric carcinogenesis remains a mystery. Intestinal metaplasia (IM) and spasmolytic polypeptide expressing metaplasia (SPEM) are the two types of preneoplastic metaplasias. In this study, we aimed to investigate expression of Pancreatic duodenal homeobox 1 (PDX1), mucins (MUCs), trefoil factors (TFFs) in SPEM and IM surrounding gastric carcinomas.

Glandular carcinomas of the larynx are rare tumors that constitute less than 1% of all laryngeal malignancies where "adenocarcinoma not otherwise specified" is the most common histologic subtype. Here we report a case of a 70-year-old female patient with primary laryngeal mucinous adenocarcinoma.

Methods: Fifty Wistar albino rats were randomly assigned to 5 groups (10 rats in each). Bile duct was ligated in 40 rats and they were treated as follows: group vitC, vitamin C 10 mg/kg sc daily; group vitE, vitamin E 15 mg/kg sc daily; group vitEC, both of the vitamins; bile duct-ligated (BDL, control) group, physiological saline sc.
Aims And Background: Thyroid transcription factor (TTF-1) is a tissue-specific transcription factor expressed in the epithelial cells of thyroid and lung. The aim of this study was to evaluate the relationship between the expression of TTF-1 and clinico-pathological parameters in pulmonary adenocarcinoma and adenosquamous carcinoma.
Methods: Resection material of pneumonectomies and lobectomies of 39 patients was retrospectively examined.
Background: The aim of this study was to evaluate the expression of Bcl-2 and Ki-67 in tamoxifen (TAM)-associated endometrial polyps and postmenopausal polyps.
Material And Methods: For this purpose, a retrospective analysis of paraffin-embedded specimens was carried out. Polyps of 20 postmenopausal and 14 TAM-treated patients, 11 simple endometrial hyperplasia, 10 atypical complex endometrial hyperplasia and 8 endometrial adenocarcinoma specimens were included in the study.
Background: Placenta percreta in early pregnancy has been documented in only a few cases. This is the first report of placenta percreta diagnosed after an extended period from pregnancy termination.
Case: A woman with a history of a previous cesarean section presented with heavy and irregular vaginal bleeding beginning immediately after pregnancy termination at 7 weeks' gestation.
Chest wall hamartomas are extremely rare. Frequently mesenchymal hamartomas are presented as a single mass and contain some primitive mesenchymal elements such as chondroid and trabecular bone structures. A 60-year-old man presented to hospital with chest pain.

Heparin, indomethacin, pentoxifylline or saline were administered simultaneously with LPS. In addition, a control group was formed which was administered only saline.

Objective: The aim of this study was to determine the effects of supplementation with vitamins E and C on antioxidant enzyme status and histologic changes in hepatic tissue in a rat model of alcoholic liver disease.
Lymphoepithelioma-like carcinoma (LELC) of the urinary bladder is very rare. It is mandatory to make differential diagnosis among lymphoma, chronic cystitis and LELC because of different therapeutic approach. A bladder tumor was found in a 90-year-old patient suffering from hematuria.

The level of p27 protein expression decreases during tumor development and progression in some epithelial, lymphoid and endocrine tissues.

Purpose: The aim of this study is to determine the cardioprotective efficacy of amifostine. The study consists of researching the relationship between plasma brain natriuretic peptide levels and the electrical and morphologic changes in irradiated rats with or without amifostine.
Methods And Materials: Sixty Wistar albino rats were divided into 4 groups, and their hearts were given 15 Gy/fraction with (60)Co.
Primary lung tumors mimicking the salivary gland-type neoplasms are extremely rare. These types of tumors originate from submucosal bronchial glands. Epithelial-myoepithelial carcinoma is an uncommon tumor in this group, and only 7 cases have been reported.
