Drilling boreholes in gas zones and with the possibility of migration or exhalation requires a high index well tightness. An important parameter determining effectiveness sealing annular space is adhesion cement sheath to rock formation. Low values formation casing surface result uncontrolled flows. The lack also reduces stabilization pipe column. To obtain required adhesion, should be properly...

Intraabdominal adhesions develop after abdominal surgery as part of the normal healing processes that occur after damage to the peritoneum. Over the last 2 decades, much research has gone into understanding the biochemical and cellular processes that lead to adhesion formation. The early balance between fibrin deposition and degradation seems to be the critical factor in adhesion formation. Alt...

Postoperative adhesion formation is a major clinical problem. It has been demonstrated that the pneumoperitoneum used during laparoscopy is a cofactor in adhesion formation. Reactive oxygen species (ROS) are produced in a hyperoxic environment and during the ischaemia/reperfusion process. ROS activity is deleterious for cells, which protect themselves by an antioxidant system known as ROS scave...

The pathophysiology of adhesion formation needs to be clarified to reduce the adhesion-related morbidity. The epithelial characteristics of the peritoneum suggest a protective role against adhesion formation, yet how the peritoneum is involved in adhesion formation is not well characterized. We microscopically observed an experimental model of adhesion formation to investigate the effects of an...

The fibronectin (FN)-binding integrins alpha4beta1 and alpha5beta1 confer different cell adhesive properties, particularly with respect to focal adhesion formation and migration. After analyses of alpha4+/alpha5+ A375-SM melanoma cell adhesion to fragments of FN that interact selectively with alpha4beta1 and alpha5beta1, we now report two differences in the signals transduced by each receptor t...

Vascular smooth muscle cells (VSMCs) are indispensible components in foam cell formation. Salusin-β is a stimulator in the progression of atherosclerosis. Here, we showed that salusin-β increased foam cell formation evidenced by accumulation of lipid droplets and intracellular cholesterol content, and promoted monocyte adhesion in human VSMCs. Salusin-β increased the expressions and activity of...

Regulation of actin organization and dynamics is a highly complex process that involves a number of actin-binding proteins, including capping, branching, severing, sequestering, and cross-linking proteins. The actin-binding and cross-linking protein AFAP-110 is expressed in normal myoepithelial cells. Screening of different breast epithelial cell lines revealed high expression levels of AFAP-11...

In this study, a strain of lactic acid bacteria Streptococcus salivarius was studied for its capacity to remove hexavalent chromium (Cr (VI)) from a liquid medium and to form biofilm. Both properties are useful for using the strain in bioremediation of metal-contaminated effluents. For biofilm formation capacity, three methods were used: the tube method (TM), the Congo red agar method (CRA) and...

INTRODUCTION Lyme disease is a multi-organ animal-borne disease caused by the spirochete Borrelia burgdorferi (Bb). OBJECTIVES As the pathogenesis of Lyme borreliosis is not fully understood, the study has been designed to examine levels of soluble vascular cell adhesion molecule-1 (sVCAM-1) and soluble intercellular adhesion molecule-1 (sICAM-1) in serum and the cerebrospinal fluid (CSF) of ...

in the present study, variation among different bacterial strains was observed in the plaques of tobacco chewers (tc) as compared to those from normal persons (non tobacco chewers) (ntc). bacterial strain j1 (dominant in the plaques of ntc) did not initiate the process of adhesion (biofilm formation) until it appeared to have reached a required population density necessary for the production of...
