In the last two decades, monoclonal antibodies have revolutionized the therapy of cancer patients. Although antibody therapy has continuously been improved, still a significant number of patients do not benefit from antibody therapy. Therefore, rational optimization of the antibody molecule by Fc engineering represents a major area of translational research to further improve this potent therap...

introduction: this in vitro study assessed and compared the cytotoxicity of mineral trioxide aggregate (mta), calcium-enriched mixture (cem) cement, biodentine (bd) and octacalcium phosphate (ocp) on stem cells of the human apical papilla (scap). methods and materials: scaps were isolated from two semi-impacted third molars. the cells were cultured in wells of an insert 24-well plate and were t...

in this work, we calculated the several physico chemical properties containing of solubility (byvcl), lipophilicity (by milinspiration), dipole and quadrupole moments (by density functionaltheory) for 7 azt analogs, and compared these parameters with inhibition assays of them. it isresulted; cytotoxicity of these drugs is related with their lipophilicity inversely. with using of thisresult, for...

The 1,4-dihydropyridine (DHP) derivatives are a known class of calcium channel blockers. Some derivatives of DHP showed significant cytotoxicity. It was shown that this effect may not be the result of interaction with Ca2+ channels. In this study, we performed an investigation about the intrinsic cytotoxicity of some derivatives of DHP containing nitroimidazole moiety on their C4 position on fo...

Significant cytotoxic lymphocyte-induced DNA fragmentation does not occur in four human target cells lysed by human natural killer lymphocytes, killer lymphocytes, or cytotoxic T lymphocytes. These results contrast with the extensive DNA fragmentation that occurs in murine target cells lysed by the analogous effector lymphocytes. Thus, DNA fragmentation, or the lack thereof, represents a specie...

Therapeutic monoclonal antibodies (mAbs) have high efficacy in treating TNF α-related immunological diseases. Other than neutralizing TNF α, these IgG1 antibodies exert Fc receptor-mediated effector functions such as the complement-dependent cytotoxicity (CDC) and antibody-dependent cell cytotoxicity (ADCC). The crystallizable fragment (Fc) of these IgG1 contains a single glycosylation site at ...
