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 ...

Problem The most common DNA lesion generated by oxidative stress (OS) is 7, 8-dihydro-8-oxoguanine (8-oxoG) whose excision repair is performed by 8-oxoguanine glycosylase (OGG1). We investigated OGG1 expression changes in ...

Although lacking catalytic activity, the Lys49-PLA(2)s damage artificial membranes by a Ca2+-independent mechanism, and demonstrate a potent bactericidal effect. The relationship between the membrane-damaging activity and ...

Many snake venom phospholipase A(2)s (vPLA(2)s) present biological effects that are independent of hydrolytic activity. Here we review the evidence for the calcium-independent membrane damaging activity of vPLA(2)s, the ...

Lactobacillus delbrueckkii subsp. bulgaricus was dried under vacuum at different temperatures and its preservation evaluated following three parameters: lag time, percentage of membrane damage and z potential).  Microorganisms ...
