Modulatory effects of acidic ph and membrane potential on the adsorption of ph-sensitive peptides to anionic lipid membrane
(2021-05-01)
Anionic lipid membrane electrostatic potential and solution pH can influence cationic peptide adsorption to these bilayers, especially those containing simultaneously acid and basic residues. Here, we investigate the effects ...
Protective effect of safranine on the mitochondrial damage induced by Fe(II)citrate: Comparative study with trifluoperazine
(1996-08-07)
In this study, we show that safranine at the concentrations usually employed as a probe of mitochondrial membrane potential significantly protects against the oxidative damage of mitochondria induced by Fe(II)citrate. The ...
Bovine sperm cells viability during incubation with or without exogenous DNA
(CAMBRIDGE UNIV PRESS, 2009)
The aim of this study was to assess the effect of exogenous DNA and incubation time on the viability of bovine sperm. Sperm were incubated at a concentration of 5 x 10(6)/ml with or without plasmid pEYFP-NUC. Fluorescent ...
Impact of Ciprofloxacin and Chloramphenicol on the Lipid Bilayer of Staphylococcus aureus: Changes in Membrane Potential
(Hindawi Publishing Corporation, 2013-05)
The present study was undertaken to explore the interaction of ciprofloxacin and chloramphenicol with bacterial membranes in a sensitive and in a resistant strains of Staphylococcus aureus by using 1-anilino-8-naphthalene ...
Influence of membrane-solution interface on the selectivity of SnO2 ultrafiltration membranes
(Elsevier B.V., 2001-03-01)
SnO2 supported membranes, presenting 3.0 nm average pore size, have been produced by sol casting on alumina tubular substrate using aqueous colloidal suspensions prepared by sol-gel route. The selectivity and flux throughout ...
