The incidence of recurrent infections in chemical injuries made us guess that phagocytic system of these patients has been disordered. On the other hand, deficiency of phagocytic function in scalds has been proved and superficial burns seen in these subjects also encouraged us to study the condition of their neutrophils. Neutrophils are one of the main members of natural immunity an...
Two cell lines with different in vitro growth patterns were established from the pleural fluid of a patient with malignant epithelial pleural mesothelioma. The cell line established in RPMI 1640 supplemented with human AB serum had an epithelial morphology, while the cell line established in fetal calf serum-supplemented medium had a fibroblast-like morphology. Exposure of the fibroblast-like c...
Background: Erythrocytes require an ability to deform and to withstand shear stress while negotiating the microcirculation. These properties are largely due to their excess surface area per volume and the characteristics of the membrane’s protein. Deficiencies of these proteins are associated with chronic haemolysis. Methods: This was a cross sectional study aimed at determining the prevalenc...
Background Sperm preparation before assisted reproductive techniques is very important for obtaining successful fertilization and pregnancy. During ICSI technique, sperms are selected based on viability and morphology. But this selection did not guarantee integrity of sperm DNA. Therefore, novel sperm selection procedures are introduced for selection of sperm with low DNA damage. One of these p...

Background: Many sperm characteristics including, motility and morphology are important for normal spermatozoa- oocyte intraction. These features may be altered during vitrification. Motile sperm organelle morphology examination (MSOME) is an unstained real time high magnification technique that analysis viable sperm morphology instantly. This study aimed to investigate the influence of vitrifi...

Tight junctions, which locate at the apicolateral borders of epithelial cells to seal intercellular space, are previously proposed connect circumferential actomyosin belt, whose contractility exerting line tensions affects paracellular transport by opening pores tight junctions. Although junctions known display tortuous morphology, tension leads straight tight-junction morphology as energy mini...
The importance of extra cellular matrix (ECM) in development and function of different cells has been reported but little is known about its role in human endometrial epithelial cells. The aim of the present study was to examine effects of artificial ECM (Matrigel) and progesterone on the function and morphology of human endometrial epithelial cells in vitro. Methods: Endometrial samples were ...
Purpose: The objective for this study is to investigate the morphology and ultrastructure of mouse endometrial epithelial cell monolayer cultured on matrigel in dual-chambered system as an in vitro mouse endometrial epithelial cell culture model that mimics structural and functional properties of the endometrial epithelium in vivo. Materials and Methods: Mouse endometrial epithelial cells were...
