Background To report normal variations of the limbal structures using in vivo laser scanning confocal microscopy. Methods: This was a retrospective study of fourteen eyes from 11 healthy individuals. Confocal imaging of cornea and limbus was performed using Heidelberg Retina Tomograph III Rostock Corneal Module. Results: The typical structure of the palisades of Vogt (POV) was detected ...
Experimental renal disease was produced in young rats by daily subcutaneous injections of 6-dimethylamino purine, 3-amino-d-ribose (aminonucleoside). The physiologic, biochemical, and light microscopic changes were similar to those observed in human nephrosis. Electron microscopy of the glomeruli from animals which received seven or more daily injections of aminonucleoside revealed characterist...
Background and aim: In this study the cytotoxicity to human epithelial lung cells of single-walled carbon nanotubes, multi-walled carbon nanotubes and chrysotile was compared based on the following cytotoxicity indices: no observable adverse effect concentration (NOAEC), inhibitory concentration 50 (IC50), and Total Lethal Concentration (TLC). Materials and Methods: Human epithelial lung cells...
ATP release by nonpigmented (NPE) and pigmented (PE) ciliary epithelial cells is the enabling step in purinergic regulation of aqueous humor formation, but the release pathways are unknown. We measured ATP release from primary cultures of bovine mixed NPE and PE (bCE) cells and transformed bovine NPE and PE cells, using the luciferin-luciferase reaction. Hypotonicity-triggered bCE ATP release w...
Abstract Background: Various studies indicated that epithelial cells derived from the amniotic membranes of human term placenta have inhibitory effect on components of the innate or acquired immune system. On the other hand, during pregnancy one of the most inhibitory mechanisms of fetal survival maybe though to close contact between AECs and maternal myeloid derived (DCs) that leads to generat...
abstractgene therapy is a therapeutic approach to deliver genetic material into cells to alter their function in entire organism. one promising form of gene delivery system (dds) is liposomes. the success of liposome-mediated gene delivery is a multifactorial issue and well-designed liposomal systems might lead to optimized gene transfection particularly in vivo. liposomal gene delivery systems...
the toxic impact of copper sulfate in lethal and sublethal concentrations was investigated on gill of grass carp, ctenopharynogodon idella . in this investigation, 27 specimens were used as control group and three treatment groups were treated with 2.5 and 5mg/l of copper sulfate. gill samples were collected from each treatment after 96hr and lesions were analyzed by light microscopy. in histop...
Purpose: Separation, prolifration of stem cells and repairing of injured parts using these cells. Materials and Methods: This was a Lab-Experimental study. We used 6 male albino rabbits. At first, under general anesthesia 5x5 cm2 full thickness skin from one of the rabbits separated, washed using 70% alcohol and inserted in cold HBSS. Then it was cut into 4-6 mm pieces, washed again and incubat...
Background : Aquaporin1 (AQP1) protoin channels that expressed in the Choroid plexuses of brain ventricles, have an important role in cerebrospinal fluid (CSF) production. Some pathophysiological conditions such as intracranial hypertension, systemic hyponatremia and hydrocephalus followed by overproduction of CSF. Studies indicated that Curcumin can inhibit ionic channels. So the aim of this s...
