Light-Controlled ZrO2 Surface Hydrophilicity
In recent years many works are aimed at finding a method of controllable switching between hydrophilicity and hydrophobicity of a surface. The hydrophilic surface state is generally determined by its energy. Change in the surface energy can be realized in several different ways. Here we report the ability to control the surface wettability of zirconium dioxide nano-coatings by changing the comp...
متن کاملThe Activation-Induced Decrease in the Platelet Surface Expression
Thrombin decreases the platelet surface expression of the glycoprotein (GP) Ib-IX complex. To determine whether this effect is reversible, flow cytometric studies were performed with GPlb-IX-specific monoclonal antibodies. In both whole blood and washed platelet systems, incubation of platelets with thrombin or a combination of adenosine diphosphate and epinephrine resulted in a maximal decreas...
متن کاملAmplification of human platelet activation by surface pannexin-1 channels
BACKGROUND Pannexin-1 (Panx1) forms an anion-selective channel with a permeability up to ~1 kDa and represents a non-lytic, non-vesicular ATP release pathway in erythrocytes, leukocytes and neurons. Related connexin gap junction proteins have been reported in platelets; however, the expression and function of the pannexins remain unknown. OBJECTIVE To determine the expression and function of ...
متن کاملChanges in surface-bound and exchangeable calcium during platelet activation.
Using 45CaCl2, we measured the effect of ADP and epinephrine on exchangeable Ca2+ pools in gel-filtered platelets. Unstimulated platelets contained 1) a slowly exchangeable pool, representing 54% of the exchangeable Ca2+, that was unaffected by ethylene glycol bis(beta-aminoethyl ether)-N,N,N'N'-tetraacetic acid and was, therefore, presumably intracellular; and 2) a rapidly exchangeable pool, r...
متن کاملA Novel Platelet Concentrate: Titanium-Prepared Platelet-Rich Fibrin
We developed a new product called titanium-prepared platelet-rich fibrin (T-PRF). The T-PRF method is based on the hypothesis that titanium may be more effective in activating platelets than the silica activators used with glass tubes in Chouckroun's leukocyte- and platelet-rich fibrin (L-PRF) method. In this study, we aimed to define the structural characteristics of T-PRF and compare it with ...
