Background: This study was undertaken to establish the characterization of cultured oral mucosal epithelium and introducing them as an alternative source for reconstruction of ocular surface disease. Methods: Human oral epithelial cells were cultured on simple media (DMEM/HF12) as control and co-cultured on mitomycin C-treated 3T3 feeder layer, on the amniotic membrane (AM) without nitrocellulo...

Anthrax toxin consists of three proteins: lethal factor (LF), edema factor (EF), and protective antigen (PA). This last forms a heptameric channel, (PA(63))(7), in the host cell's endosomal membrane, allowing the former two (which are enzymes) to be translocated into the cytosol. (PA(63))(7) incorporated into planar bilayer membranes forms a channel that translocates LF and EF, with the N termi...

Axial distributions of plasma and floating potentials, electron number density and the electron energy distribution function (EEDF) have been measured in the double layer (DL) region of an He discharge constriction. Excitation processes in the constriction region are studied. Using a linearization method for the nonstationary balance equations and choosing appropriate discharge conditions, ...

Abstract: In this research plasma nitriding of pure aluminium and effect of iron elemental alloy on the formation and growth of aluminium nitride was investigated. Also corrosion properties of formed AlN were investigated. After preparation, the samples were plasma nitrided at 550oC, for 6, 9 and 12 h and a gas mixture of 25%H2-75%N2. The microstructure and phases analysis were investigated usi...

Clothing production have adverse impact on the environment due to inefficient energy utilization during processing, huge consumption of water and usage harmful chemicals. Therefore, this work aims develop a sustainable wind resistant repellant fabric through novel technology that reduces processing steps for efficient without compromising required functional performances durable repellency coat...

Although archaeological excavations have recovered a large number of vessels used to hold perfumes or ointments in ancient Rome, little is known about the chemical composition origin substances they contained. Most available information pertains ointment and/or cosmetic bases rather than essences. The discovery 2019 an jar (unguentarium) made rock crystal (quartz) that was sealed with stopper a...

introduction: the purpose of the present study was to evaluate the different concentrations of sodium hypochlorite activated with laser in removing of the smear layer in the apical, middle, and coronal segments of root canal walls by scanning electron microscopy analysis. methods: sixty single-rooted human mandibular teeth were decoronated to a standardized length. the samples were prepared by ...
