Tenascins are extracellular matrix glycoproteins associated with cell motility, proliferation and differentiation. Tenascin-C inhibits cell spreading by binding to fibronectin; tenascin-R and tenascin-X also have anti-adhesive properties in vitro. Here we have studied the adhesion modulating properties of the most recently characterized tenascin, tenascin-W. C2C12 cells, a murine myoblast cell ...

In this paper dynamic damping properties of a nominated flexible structural adhesive have been identified using an extended-direct modal based joint identification method. It has been revealed that damping characteristics of adhesive are correlated to both frequency and mode shape. Young’s and shear moduli increase with frequency but damping on the other hand, decrease. The results showed that ...

Bacterial contact leaching of ores is more effective than non-contact leaching. Adhesion is the first step for leaching bacteria to form a biofilm on a mineral surface. Extracellular polymeric substances (EPS) are pivotal for mediating bacterial adhesion to a substratum. In order to clarify the role of EPS, we measured the adhesion forces between chalcopyrite-, sulfuror FeSO4·7H2O-grown cells o...

Two key steps in kidney stone formation--crystal aggregation and attachment to renal tissues--depend on the surface adhesion properties of the crystalline components. Anhydrous uric acid (UA) is the most common organic crystalline phase found in human kidney stones. Using chemical force microscopy, the adhesion force between various functional groups and the largest (100) surface of UA single c...

the influence of increasing the sio2/k2o molar ratio on the electrochemical action of a waterbornepotassium silicate zinc-rich coating was investigated by means of electrochemical impedancespectroscopy (eis) and corrosion potential (ecorr) measurements. the eis results showed thatincreasing the sio2/k2o molar ratio in the range of 3.135 to 5 by the addition of nano-sio2 to theresins improved th...

In this work, modified silicone tie-paints were prepared in a simple way for securing adhesion between the epoxy anticorrosive primer and fouling release coating. Hydroxy-terminated polydimethylsiloxane (PDMS) mixture containing fillers accessory ingredient was as base component. N-(2-Aminoethyl)-3-aminopropyltrimethoxysilane (DAMO) mechanically mixed with other functional additives curing ATR-...

Background: Tissue engineering has been investigated as a potential method for healing traumatized tissues. Biomaterials are material devices or implants used to repair or replace native body tissues and organs. The present study was conducted to evaluate the effects of decontamination methods on biological/mechanical properties and degradation/adhesion test of the platelet‑-rich fibrin (PRF) m...

This paper is devoted the study of a generalized hybrid dynamical system, which consists history-dependent hemivariational inequality parabolic type and nonlinear evolution equation. The unique solvability for system established via applying surjectivity multivalued pseudomonotone operators, fixed point theorem, properties Clarke gradient. As an illustrative application, dynamic frictional cont...
