Oral carcinogenesis, a multistep process with multifaceted etiology, arises due to accumulation of heterogeneous genetic changes in the genes involved in the basic cellular functions including cell division, differentiation, and cell death. These genetic changes in the affected cell progressively increase the cell proliferation, angiogenesis, and inhibition(More)
We present a theoretical analysis of the band-edge exciton structure in nanometer-size crystallites of direct semiconductors with a cubic lattice structure or a hexagonal lattice structure which can be described within the framework of a quasicubic model. The lowest energy exciton, eightfold degenerate in spherically symmetric dots, is split into five(More)
Carcinogen induced mutation in somatic cells leads to genetic instability, which is considered as an important facet of carcinogenesis. Agents that inhibit DNA adduct formation, stimulate DNA repair mechanisms, and possess antioxidant functions are considered as antigenotoxic agents. Genistein, the major isoflavone of soy products, protects animals against(More)
AIM The quest to identify an accurate method of age estimation, had lead to the evaluation of aspartic acid racemisation in hard tissues of the human remains using high performance liquid chromatography (HPLC). Our study is aimed at the applicability of the racemisation technique to use dentin as the sample to estimate the age in South Indian(More)
