Analysis of chromatin integrity and DNA damage of buffalo spermatozoa
This study was conducted to determine chromatin integrity and DNA damage by DNA electrophoresis and comet assays of buffalo fresh and frozen semen. Semen samples were collected from four buffalo bulls and evaluated after freezing for semen motility, viability, sperm abnormalities, chromatin integrity and DNA damage. A significant variation was found in semen parameters after thawing. Highly sig...
متن کاملEffect of PolyVinyl Pyrrolidone on Sperm Membrane Integrity and Chromatin Status
Background The aim of present study is to evaluate the effect of PolyVinyl Pyrrolidone (PVP) routinly used during ICSI procedure on sperm membrane integrity, and sperm chromatin status. MaterialsAndMethods This study was carried out on 21 semen samples from the infertile men referring to Isfahan Fertility and Infertility Center. The processed semen samples were divided into two portions. One po...
متن کاملP-4: Zaditen (Ketotifen), as Mast Cell Blocker, Improves Sperm Quality, Chromatin Integrity and Pregnancy Rate after Varicocelectomy
Background: Surgery is considered the most common choice for the treatment of male infertility with clinical varicocele. Increased numbers of mast cells (MCs) have been associated with different types of infertility, including varicocele. Despite there being different reports on improved fertility following administration of MC blockers, there is no report on the effect of a MC blocker on varic...

متن کاملLectins as probes of chromatin structure. Binding of concanavalin A to purified rat liver chromatin.
Concanavalin A (Con A) binds specifically to rat liver chromatin. The extent of binding is directly proportional to both chromatin and concanavalin A concentration. It is reversible and inhibited by specific sugars for which concanavalin A has a binding site. Scatchard analysis reveals the presence of one type of Con A-binding site, with an apparent dissociation constant of 3 X 10(-7) M. A maxi...
