Our knowledge of the molecular structure and the role of cell receptors and soluble mediators controlling immune responses has increased tremendously over the last 10 years. Likewise the concept of bioincompatibility resulting from the interaction between extracorporeal blood and the dialysis circuit has been extended far beyond its original definition by complement activation and subsequent pu...

OBJECTIVE Use of the SMart piston, a nitinol-based, self-crimping prosthesis in stapes surgery may allow improved functional results because of better sound transmission properties at the incus-prosthesis interface because of the elimination of manual crimping. Possible disadvantages include thermal damage or strangulation of the incus and its mucoperiosteum or nickel intolerance. The goal of t...

Toxicity of a material upon placement in patient’s oral cavity triggers the immune system to elucidate an appropriate response. Thus, one of the many fundamental responsibilities bestowed on the dentist is to shield patients from any untoward reaction. A plethora of dental materials is currently available in the market. The material has to advance several tests in order to be safely introduced ...

The acellular dermal matrix allograft has been used as an alternative to autogenous palatal mucosal graft. The aim of this study was the evaluation of the biocompatibility of an acellular dermal matrix (AlloDerm) in culture of macrophages. For hydrogen peroxidase determination we used the method of Pick & Kesari, and the Griess method for nitric oxide determination. Statistical analysis showed ...
