Centrifugal damage has been known to alter bacterial cell surface properties and interior structures, including DNA. Very few studies exist on bacterial damage caused by centrifugation because of the difficulty in relating centrifugation speed and container geometry to the damage caused. Here, we provide a simple, versatile method of analysis for describing the compaction of bacteria during cen...

This study was aimed at investigating the effects of sperm centrifugation on nitric oxide (NO) and reactive oxygen species (ROS) generation as well as sperm motility and viability. Human spermatozoa were centrifuged for 10 and 30 minutes (400 x g) in the presence or absence of the NOS inhibitor, N G -nitro-L-arginine methyl ester (L-NAME); ROS scavenger, N-(2-mercaptopropionyl)Glycine (MPG) or ...
