Tumor necrosis factor-α converting enzyme (TACE) is a cell membrane sheddase, expressed in both developmental lung epithelia and mesenchyme. Global abrogation of TACE results in neonatal lethality and multiple organ developmental abnormalities, including dysplastic lung. To further define the roles of TACE in regulating lung development, lung epithelial and/or mesenchymal specific TACE conditio...

among the drug delivery and targeting (ddt) routes, lung alveolar epithelium has been given enormous attentions in terms of the delivery of a wide range of macromolecules such as gene- or protein-based nanopharmaceuticals. however, little is known about cellular modulation of lung transport characteristics by endogenous and/or exogenous agents. thus, in the current study, impact of dexamethason...

INTRODUCTION Women presenting with unhealthy cervix needs to be evaluated with Papanicolaou (Pap) smear for epithelial abnormalities. AIM To detect epithelial cell abnormalities in unhealthy cervix using the 2001Bethesda system of reporting for cervical cytology and to confirm histopathologicaly the findings of Pap smear. MATERIALS AND METHODS In this study, 125 women with clinical diagnosi...

aflatoxins are toxic compounds which are produced by aspergillus flavus and a. parasiticus. these toxins can be transmitted into the animal body via contaminated feed. when these toxins enter the animal body, they can penetrate into different tissues. one of the most important tissues which can be influenced by aflatoxin is the mammary gland. milk protein is one the most important factors in de...

The leakiness of the cell membranes of colonic epithelial cells isolated by the collagenase/Dispase technique from normal or diseased colons was assessed in a 4 h 51Cr release assay. Cells from normal, adenoma bearing or cancer bearing colons showed 51Cr release of 8% or less in almost all of 46 cell populations tested. In contrast, cells from mucosa affected by ulcerative colitis [11.9 (4.3%) ...

Colorectal epithelial neoplasia (CR-EN), both adenoma and adenocarcinoma, may develop from the essential tubules of the colorectum. In order to conclude the carcinogenesis of the colorectal cancer more clearly, the biological features including the genetic abnormality of the nonneoplastic mucosal epithelium of colon and rectum, which coexist in connection with CR-EN, should be investigated. In ...

purpose: to evaluate the corneal endothelial cell density and polymegathism one year after laser assisted keratomileusis using mitomycin c. methods: one hundred and three eyes from 52 patients who underwent laser assisted sub-epithelial keratomileusis using mitomycin c 0.02% for 30 seconds entered this study. corneal endothelial cells were evaluated using specular microscopy before and one year...

purpose : to develop a guideline for the treatment of incompletely removed histopathologically documented ocular surface neoplasia (ossn) with mitomycin c (mmc). materials & methods : through an interventional case series, 17 eyes of 17 patients presented with incompletely removed ossn were treated according to a protocol using 2-3 alternate 7-day courses of mmc 0.04%. clinical recurrence was r...

OBJECTIVE There is no other screening program close to the success rate of PAP test. Cervical cytology constitutes a large workload so that quality control in cervical cytology is important for the quality assurance of pathology laboratories. MATERIAL AND METHOD In this study, we collected the cervical cytology results from all over Turkey and discussed the parameters influencing the quality ...
