Biochemical and biophysical research communications, 275(3), 946-954 (2000-09-07)
It has been shown that rheological abnormality might be an etiological factor in hypertension. Recent studies have revealed that human erythrocytes possess a nitric oxide (NO) synthase and that this activation might be involved in the regulation of rheological properties
I Yruela et al.
Biochimica et biophysica acta, 1515(1), 55-63 (2001-10-13)
The effect of fatty acid desaturation on lipid fluidity in thylakoid membranes isolated from the STR7 mutant was investigated by electron paramagnetic resonance (EPR) using spin label probes. The spectra of both 5- and 16-n-doxylstearic acid probes were measured as
X Qi et al.
Circulation, 104(13), 1544-1549 (2001-09-26)
The maintenance and termination of reentry arrhythmias are determined by tissue properties such as refractoriness and conduction velocity. Although the effects of Na(+) and K(+) channel block on electrophysiological properties and defibrillation threshold (DFT) have been studied, little is known
M A Baqué et al.
Biochemical and biophysical research communications, 505(4), 1038-1042 (2018-10-13)
Different spin labels were incorporated to the membranes of cultured insect UFL-AG-286 cells in order to characterize their physical properties by Electron Paramagnetic Resonance spectroscopy (EPR). The spectrum of the spin label 12-SASL incorporated to cell membranes was similar as those
