Background and Aims: It has been suggested that thyrotropin-releasing hormone (TRH) may have functions beyond its fundamental regulating function. Previous studies demonstrated TRH promotes wound healing. We aimed to perform an in vitro study fibroblasts assess the role of wounds frequently occur diabetes. Thus, we investigated effects healing both under normoglycemic hyperglycemic-conditions....

Bleaching agents can potentially cause damage to dental and gingival tissues. Due to the use of bleaching agents close to gingival tissues, the objective of the present study was to test the hypothesis that the higher the concentration of hydrogen peroxide, the greater is the cytotoxicity to fibroblast cells. Two concentrations of hydrogen peroxide (6%, and 7.5%) used in home bleaching techniqu...

Surface modification of biomaterials is a way to tailor cell responses whilst retaining the bulk properties. In this work, chitosan membranes were prepared by solvent casting and treated with nitrogen or argon plasma at 20 W for 10-40 min. AFM indicated an increase in the surface roughness as a result of the ongoing etching process. XPS and contact angle measurements showed different surface el...

1,3-Thiazolidin-4-one analogues are important because of its versatile biological actions. In the present study, benzohydrazide (1) on condensation with different aromatic aldehydes (2a-g) in presence of catalytic amount of concentrated hydrochloric acid in absolute ethanol yield N'-[(E)(substitutedphenyl)methylidene]benzohydrazide (3a-g), which on cyclisation with 2sulfanylpropanoic acid in dr...

This study examines the functional relationship between glioma cell production of hyaluronan (HA), known to play a role in glioma invasion, expression of its CD44 receptor, and glioma cell viability. Production of HA by CD44 positive mouse G26 and human U373 glioma cell lines was evaluated and compared to that of a CD44 positive mouse fibroblast-like L929 cell line. We found that both G26 and U...

INTRODUCTION The aim of this study was to compare the cytotoxicity of Mineral Trioxide Aggregate (MTA) and a New Endodontic Cement (NEC) on L929 mouse fibroblasts. MATERIALS AND METHODS Different dilutions (Neat, 1/2, 1/10, 1/100) of fresh and set materials placed adjacent flasks of L929 in DMEM medium. Cellular viability was assessed using MTT assay in three time intervals (24, 48, and 72 h ...

Introduction: Iron plays an important role in physiological processes as a trace element. Today, iron oxide nanoparticles have attracted extensive attention due to their super paramagnetic properties and a variety of potential applications in many fields. The main objective of this study was to evaluate in vitro and in vivo toxic effects of the iron oxide nanoparticles on L929 cell line, kid...

Some cell detection approaches which deal with bright-field microscope images utilize defocussing to increase the image contrast. The latter is related to the physical light phase through the transport of intensity equation (TIE). Recently, it was shown that it is possible to approximate the solution of the TIE using a modified monogenic signal framework. We show empirically that using the loca...

In the present investigation, a compatibilized blend of thermoplastic polyurethane (TPU) and polydimethylsiloxane (PDMS) is prepared by using copolymer of ethylene and methyl acrylate (EMA) as a reactive compatibilizer. Detailed in vitro biocompatibility studies were carried out for this compatibilized blend and the material was found noncytotoxic towards L929 mouse fibroblast subcutaneous conn...
