Elevated micronucleus frequency in patients with type 2 diabetes, dyslipidemia and periodontitis.

abstract：:Nanoremediation of soil, ground and surface water using nanoscale zerovalent iron particles (nZVI) has facilitated their direct environmental exposure posing ecotoxicological concerns. Numerous studies elucidate their phytotoxicity in terms of growth and their fate within the plant system. However, their potential gen...
