Introduction: Oral Lichen Planus (OLP) is one of the most common mucocutaneous lesion, and its etiologic factors have not been elucidated yet. OLP has two different clinical forms including reticular and erosive. Mast cells function in non-specific immunology is an etiologic factor involved in the formation of lichen planus. This study aimed at determining the pattern of mast cells presence in ...

Infection with Chlamydia trachomatis targets epithelial cells within the genital tract which respond by secreting chemokines and cytokines. Persistent inflammation can lead to fibrosis, tubal infertility and/or ectopic pregnancy; many infections are asymptomatic. Most studies have investigated the inflammatory response in the initial stages of infection, less is known about the later stages of ...

Recent studies have shown that extracellular vesicles may play an important role in modulating the fertilization capacity of sperm during their journey through female reproductive tract. Extracellular (EVs), exosomes and micro vesicles, are a type heterogeneous structures present most body fluids, including bovine oviductal fluid. EVs contain various compounds derived from original cell, such a...

In cattle, molecular control of oviduct receptivity to the embryo is poorly understood. Here, we used a bovine model for receptivity based on size of the pre-ovulatory follicle to compare oviductal global and candidate gene transcript abundance on day 4 of the estrous cycle. Growth of the pre-ovulatory follicle (POF) of Nelore (Bos indicus) cows was manipulated to produce two groups: large POF ...

Background and objective:Cytogenetic damage in exfoliated buccal epithelial cells due to environmental and occupational exposure is often monitored by micronucleus (MN) assay using liquid based cytology (LBC) preparations. This study was performed to evaluate MN in exfoliated buccal epithelial cells of building construction workers using LBC preparations. <strong...

Objective: Helicobacter pylori has a well-established role in the development of gastric cancer. In vitro studies reveal increased proliferation of the gastric mucosa in the presence of H. pylori infection. It has been also shown that production of some cytokines, such as interleukin-1 beta (IL-1b) is in...

purpose: to separate and characterize orbital fat-derived stem cells (ofscs) and compare its cellular and molecular properties with those of bone marrow-derived mesenchymal stem cells (mscs) and adipose-derived stem cells (ascs). methods: stem cells from orbital fat, abdominal fat and bone marrow aspirates have been isolated. we assessed stem cell specific cell surface markers using cytometry, ...
