objective: acinetobacter baumannii (a. baumannii) has a good potential to colonize on various surfaces. as a virulence factor, adhesion to surfaces is the first step in colonization. the two-partner secretion system (tps) proteins are key factors for bacterial attachment. the purpose of this study is to identify and study the role of this family of proteins in adhesion of a. baumannii to human ...

Insulin resistance, which is highly prevalent in the elderly, is suggested to be accompanied by an increased acute phase response. Until now, it is unclear whether cellular adhesion molecules are involved in the clustering of insulin resistance. In the present study, we examined the relationship of insulin resistance (measured by postload insulin) with levels of markers of inflammation and cell...

the hallmarks of leukocyte adhesion deficiency (lad) are defects in the leukocyte adhesion process, marked leukocytosis and recurrent infections. these molecular and clinical manifestations result from an impaired step in the inflammatory process, namely, the emigration of leukocytes from the blood vessels to sites of infection, which requires adhesion of leukocytes to the endothelium. over las...

Objectives: Postsurgical adhesion is one of the common complications after surgery. Some anti-adhesion barriers are commercially available which are not customary used by physicians as much as expected because of ineffectiveness. Recently, nanofibers have been introduced as anti-adhesion barriers with t...

An attempt was made to correlate mechanical and tribological properties of Zn-40Al-2Cu-2Si alloy the relationships between these were determined by linear regression analysis. The this observed be expressed or simple straight-line equations. These showed that as hardness tensile strength increase friction coefficient, working temperature, wear volume it decrease but its average surface roughnes...

The aim of this study was to define concentration changes of soluble adhesion molecules (sICAM-1, sVCAM-1 and sE-Selectin) in cerebrospinal fluid and plasma, as well as, number of peripheral blood leukocytes and the albumin coefficient in the patients with the acute brain infarction. We also, analyzed the correlation between the measured levels, the infarct volume and the degree of neurological...

In this work, we present a statistical mechanical analysis to elucidate the molecular-level factors responsible for the static and dynamic properties of polymer films. This analysis, which we term conformal sites theory, establishes that three dimensionless parameters play important roles in determining differences from bulk behavior for thin polymer films near to surfaces: a microscopic wettin...

A plate-fin heat exchanger is a type of heat exchanger widely used in air conditioners, and tubes and fins are tightly assembled by the mechanical expansion process of tubes. The tube expansion process deforms the grooves inside the tube, and the groove shapes also affect the adhesion between tubes and fins. In this study, the adhesion and heat transfer performance affected by the tube expansio...

Abstract Abrasives, such as oxides of alumina (Al), silica (Si), zirconia (Zr), chromium (Cr) etc., are added to raise the friction level and also remove glaze on disc so that surface will be rejuvenated continuously during braking contribute maintain desired level. However, these inorganic particles have less adhesion with resin/binder hence easily dug out wearing process contributing higher w...

Diamond-like carbon (DLC) coatings have been the object of research interest due to properties such as excellent wear resistance, low coefficient friction, high hardness, elastic modulus, and biocompatibility. Despite this, DLC has poor adhesion properties, which makes it challenging use in industrial applications. The application using high-power pulse magnetron sputtering (HiPIMS) technique w...
