Bioglass could increase cell membrane fluidity with ion products to develop its bioactivity

In vitro bioactivity of titanium-doped bioglass.

Previous studies have suggested that incorporating relatively small quantities of titanium dioxide into bioactive glasses may result in an increase in bioactivity and hydroxyapatite formation. The present work therefore investigated the in vitro bioactivity of a titanium doped bioglass and compared the results with 45S5 bioglass. Apatite formation was evaluated for bioglass and Ti-bioglass in t...

Membrane reactors: A way to increase efficiency

Platelet secretory products increase low density lipoprotein oxidation, enhance its uptake by macrophages, and reduce its fluidity.

Oxidized low density lipoprotein (Ox-LDL) is considered to be involved in the atherogenic process. Factors influencing the formation of Ox-LDL are thus of importance. Oxidation of LDL in a cell-free system in the presence of copper ions was significantly increased (up to 60%) by the presence of platelet-conditioned medium, (PCM) obtained from collagen-activated platelets for the duration of the...

Shear stress induces a time- and position-dependent increase in endothelial cell membrane fluidity.

Blood flow-associated shear stress may modulate cellular processes through its action on the plasma membrane. We quantified the spatial and temporal aspects of the effects of shear stress (tau) on the lipid fluidity of 1,1'-dihexadecyl-3,3,3',3'-tetramethylindocarbocyanine perchlorate [DiIC(16)(13)]-stained plasma membranes of bovine aortic endothelial cells in a flow chamber. A confocal micros...

Erythrocyte Membrane Fluidity in

his study was conducted to investigate the values of the order parameter (S) and correlation time (τc) in electron spin resonance spectra for 5-DS(doxylstearic acid) and 16-DS (doxyl-stearic acid) in old normal controls and in patients with type 2 diabetes and stroke in order to assess any association between age-related disorders and membrane fluidity. Materials and Methods: We measured the me...
