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 ...

Biominerals are inorganic-organic hybrid composites formed via self-assembled bottom up processes under mild conditions. Biominerals show interesting physical properties, controlled hierarchical structures and robust ...

The aim of this study was to evaluate the behavior of a demineralized bone matrix membrane and a polytetrafluoroethylene (PTFE) membrane in the process of bone repair of surgical defects filled with autogenous bone in rats. ...

Integrity of the plasma membrane is essential for the maintenance of physiological conditions, metabolic activity and the shape of eukaryotic cells. In neurons, the plasma membrane surrounding the axon—the axolemma—fulfills ...

Patógenos intracelulares dependem de mecanismos específicos para conseguir entrar e sobreviver em suas células hospedeiras. Para isso, eles subvertem as vias envolvidas nos processos celulares fisiológicos. Aqui, vamos nos ...

The aim of the present study was to evaluate the use of an exclusively developed latex membrane, to act as physical barrier to aid wound healing, epithelization, and pain in the palate region after free gingival graft ...
