purpose: to report two cases of secondary epithelial iris cyst (seic) with pus-like precepitates in the cyst. patients and findings: two young men with history of penetrating trauma to the eye and primary repair developed secondary epithelial iris cyst several years later. slit-lamp biomicroscopy revealed a large cyst originating from the site of the laceration. the cyst was filled with pus-lik...

primary splenic cyst is a rare entity and majority of the cases are classified as epithelial cysts. they are uncommon, comprising only about 10% of benign non-parasitic cysts. most of the cysts are asymptomatic, and they are incidental findings during abdominal ultrasonography. we report a case of 20 years old male who presented with 1 year history of mild abdominal pain and left upper quadrant...

Tissue barriers play a crucial role in human physiology by establishing tissue compartmentalization and regulating organ homeostasis. At the interface between extracellular matrix (ECM) flowing fluids, epithelial endothelial are responsible for solute gas exchange. In past decade, microfluidic technologies organ-on-chip devices became popular as vitro models able to recapitulate these biologica...

Abstract BACKGROUNDS Transfer RNA (tRNA) is the most extensively modified in cells. Queuosine (Q)-modification a fundamental process for fidelity and efficiency of translation from to proteins. In eukaryotes, tRNA-Q-modification relies on intestinal microbial product queuine. Growing evidence indicates that tRNA modifications play important roles human diseases, e.g., type 2 diabetes. Q depleti...

The body's surfaces form the interface with the external environment, protecting the host. These epithelial barriers are also colonized by a controlled diversity of microorganisms, disturbances of which can give rise to disease. Specialized intraepithelial lymphocytes (IELs), which reside at these sites, are important as a first line of defense as well as in epithelial barrier organization and ...
