The CD56 differentiation antigen, recognized by anti-Leu-19 and NKH-1 mAbs, is a 200-220-kD glycoprotein that is expressed predominantly on human NK cells and a minor subset of T lymphocytes mediating MHC-unrestricted cytotoxicity. The recent finding that CD56 is an isoform of the neural cell adhesion molecule (N-CAM) prompted us to examine the adhesive function of CD56 in the NK-target cell in...
Manipulation of Human Mesenchymal Stem Cells by Multifunctional Graphene-PEDOT Microelectrode Arrays
In this study, we report the development of all-solution-processed multifunctional organic bioelectronics, comprising reduced graphene oxide (rGO) and dexamethasone 21-phosphate disodium salt (DEX) drug loaded poly(3,4-ethylenedioxythiophene) (PEDOT) microelectrode arrays on indium tin oxide glass, that can be used to manipulate human mesenchymal stem cell (hMSC) spreading morphology on rGO mic...
In this study, the effect of the substrate roughness on adhesion of mushroom-shaped microstructure was experimentally investigated. To do so, 12 substrates having different isotropic roughness were prepared from the same material by replicating topography of different surfaces. The pull-off forces generated by mushroom-shaped microstructure in contact with the tested substrates were measured an...
Introduction: The aim of this study was to compare the microleakage of beneath the orthodontic brackets bonded with 3 different bonding techniques and evaluate the effect of thermocycling. Methods: One hundred and twenty premolars were randomly divided into 6 groups, received the following treatment: group 1: 37% phosphoric acid gel+Unite primer+Unite adhesive, group 2: 37% phosphoric acid gel+...
BACKGROUND After thoracic surgery, adhesions between the pleura can cause substantial complications. This study investigated the effectiveness of a novel membrane utilizing surface water induction technology to prevent adhesions. METHODS Eight beagles were divided into an experimental group (five males) and a control group (three females). The experimental group underwent thoracotomy on both ...
The aetiology of vitiligo remains obscure. In this study, the role of integrins in the observed inability of melanocytes to repopulate lesional skin was investigated. Antibodies directed to alpha 2, alpha 3, alpha 5, alpha v, alpha 6, beta 1 and beta 3 integrin subunits were used. Immunohistology revealed no marked differences in the overall levels of expression of integrins between control, no...
Malignantly transformed cells usually display a rosette-like morphology of substratum adhesions (called podosomes) and disorganized microfilaments, and are often associated with elevated production of chondroitin sulphate. We previously showed that many tissues and cells express alternatively spliced multiforms of the large chondroitin sulphate proteoglycan termed PG-M (versican is one of the s...
An elastic finite element analysis was conducted to evaluate the stress distribution in the initiation zone of the adhesive rupture during the 3-point bending test. This test is used to measure the adherence between a polyepoxy adhesive and aluminum alloy with different surface treatments. The purpose is to compare, in the high stress concentration areas, the stress fields calculated using fini...
background and aims. the aim of this study was to evaluate the effect of dilution and curing methods of an etch-and-rinse adhesive and a self-etching primer from the same manufacturer at early exposure time on cytotoxicity of primary hu-man gingival fibroblasts. materials and methods. primary human gingival fibroblasts were exposed to different dilutions of adper single bond (asb) and adper pro...
The shoulder is the site of multiple injuries and inflammatory conditions that lend themselves to diagnostic and therapeutic injection. Joint injection should be considered after other therapeutic interventions such as nonsteroidal anti-inflammatory drugs, physical therapy, and activity-modification have been tried. Indications for glenohumeral joint injection include osteoarthritis, adhesive c...
