PURPOSE Local inflammation at the RPE cell layer is associated with inflammatory cell migration and secretion of proinflammatory cytokines such as tumor necrosis factor (TNF)-α. TNF-α upregulates intercellular adhesion molecule (ICAM)-1 expression on the RPE, which allows lymphocyte function-associated antigen-1 (LFA-1) to bind on leukocytes that contribute to leukocyte adhesion at sites of inf...

platelet activation and adhesion to the site of vascular injury is a dynamic process comprising reversible and irreversible phases. platelet adhesion typically occurs in a multi-step process similar to the selectin/integrin-mediated adhesion of neutrophils. this phenomenon is highly regulated and influenced by the cross-talk between platelets and injured endothelium. this cross-talk involves a ...

conclusions the impact of sugars and other factors on biofilm formation can vary depending on the type of bacteria present. results results showed that the presence of sugars has no effect on the bacterial growth rate; all three concentrations of sugars were hydrophilic and demonstrated a high affinity toward binding to the surfaces. background bacteria utilize various methods in order to live ...

BACKGROUND Adhesion of platelets onto immobilized fibrinogen is of importance in initiation and development of thrombosis. According to a recent increase in evidence of a multiple biological property of antithrombin, we evaluated the influence of antithrombin on platelet adhesion onto immobilized fibrinogen using an in-vitro flow system. METHODS Platelets in anticoagulated whole blood (29 hea...

BACKGROUND The detection of tumour cells circulating in the peripheral blood of patients with breast cancer is a sign that cells have been able to leave the primary tumour and survive in the circulation. However, in order to form metastases, they require additional properties such as the ability to adhere, self-renew, and grow. Here we present data that a variable fraction among the circulating...

asthma is considered as a chronic inflammatory airway disease and defined as increased tracheobronchial responsiveness to variety of stimuli. edema and inflammatory cell infiltration in airway is observed in the asthmatic patients. one of the essential changes in inflammation is adhesion of leukocyte to endothelium and transmigration of leukocytes to the sites of inflammation. unfortunately, li...

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 the potential of drug delivery. in the light of role of inflammation and oxidative stress in a...

  Occurrence of adhesions after pelvic and abdominal surgery is a well known problem. Previous surgical procedures are by far the most common cause of intra abdominal a adhesion. In over  10℅ of infertile women, adhesion formation is the main cause of their problem. Moreover postoperative adhesions are the most common cause of intestinal obstruction in the Western world. Although the cause of ...

Abstract Photochromic wood was fabricated by coating microencapsulated photochromic material (MP)/polydimethylsiloxane composites onto using a simple drop-coating method. Urea-melamine–formaldehyde resin used to microencapsulate the (PM) via in situ polymerization. The concentration of MP affected property surface. total color change (? E *) reached 82.2 when composite is 8%. Adhesion tests con...
