Genotoxicity tests are designed to detect the genetic damage by various mechanisms. Several guidelines have provided various tests to be conducted for testing the genotoxicity and each of the regulatory agencies around the world have developed their own requirements for mutagenicity, without realizing that the products developed or registered in one country are also going to be registered and marketed around the world. The ICH guideline of genotoxicity helps to optimize the standard battery for genetic toxicology and to provide guidance on interpretation of results. These suggested standard set of tests does not imply that other genotoxicity tests are inadequate or inappropriate, but they help in improving risk characterization for carcinogenic effects that have their basis in changes in the genetic material.

3D nanocomposites of β-TCP-HBO-Cu with improved mechanical and biological performances for bone regeneration applications.
Sci Rep
January 2025
Advanced Glass and Glass Ceramic Research Laboratory, Department of Physics, University of Lucknow, Lucknow, 226007, India.
Recently, 3-D porous architecture of the composites play a key role in cell proliferation, bone regeneration, and anticancer activities. The osteoinductive and osteoconductive properties of β-TCP allow for the complete repair of numerous bone defects. Herein, β-TCP was synthesized by wet chemical precipitation route, and their 3-D porous composites with HBO and Cu nanoparticles were prepared by the solid-state reaction method with improved mechanical and biological performances.

Titanium dioxide (TiO), a white color food additive, is widely used in bakery products, candies, chewing gums, soups, and creamers. Concerns about its potential genotoxicity have recently emerged, particularly following the European Union's ban on its usage as a food additive due to its genotoxicity potential. Conflicting in vitro and in vivo results regarding its genotoxicity highlight the need for further in-depth investigation.
