Glandular tumors of jaw bones present, most often, histopathologic features of salivary gland and, rarely, of cutaneous glandular neoplasms. They are thought to originate from odontogenic epithelium. An unusual maxillary tumor presenting as a radiolucency in the periapical area of the right permanent lateral incisor of a 74-year-old male is presented causing root resorption. Read More

Aims: Cell adhesion molecule 1 (CADM1) mediates interepithelial adhesion and is upregulated in crowded epithelial monolayers. This study aimed to examine CADM1 expression in the human endometrium of proliferative and secretory phases, and its transcriptional regulation in terms of estrogen stimuli and higher cellularity.

Main Methods: CADM1 immunohistochemistry was conducted on endometrial tissues from women in their 40s and adult mice subcutaneously injected with estradiol following ovariectomy. Read More

The present investigation focused on the morphological features of the intestine of Eurasian common moorhen by the aid of scanning electron microscopy and histological, morphometric, and statistical examinations. The intestinal villi were varied in shape along the intestinal tract; the duodenal villi were elongated and twisted, the jejunal villi were tongue-like, the ileal villi were cuboidal, and the cecal villi were tongue-like and finger-like at the base and body of the cecum. While at the apex of the cecum, it appeared as corrugated longitudinal folds and the rectal villi appeared as columns. Read More

In this study, we evaluated the structural features of the endometrial tissues, the immunohistochemical expression of MUC-1, which plays an important role in implantation, and the biochemical markers during the implantation window. Randomly chosen 18 fertile and 18 unexplained infertile women that have 27-32 days long menstrual cycle, normal hormonal values, normal USG findings of ovary and endometrium were included. Five, six, and seven days after ovulation, endometrial biopsies were taken and prepared in accordance with light and electron microscopy tissue preparation methods. Read More

Introduction: Fallopian tube prolapse (FTP) is a rare complication of hysterectomy. The cytological features of the prolapsed fallopian tube in vault smears have been occasionally described in the literature.

Materials And Methods: This was a retrospective study conducted to identify and describe the characteristic cytologic features of histopathologically confirmed cases of FTP in SurePath™ liquid-based preparations. Read More
