Purpose: Head and neck cancers (HNCs) are in general treated with conventional fractionation regimen of 1.8-2 Gy per fraction. Altered fractionation (ALFT) strategies such as hypofractionation radiotherapy (HYPO-RT), accelerated fractionation radiotherapy (AFRT), and hyperfractionation radiotherapy (HFRT) have not been practiced uniformly across centers in different parts of the world.

The aim of the current study was to assess the prognostic value of the  gene in the DNA damage response pathway in gastric cancer (GC). Expression levels of the were measured in 220 GC tumor tissues and adjacent healthy/noncancerous tissues using real-time PCR and immunohistochemical staining. Genomic instability in GC patients was measured using the long-run real-time PCR technique for DNA-damage quantification assay and comet assay.

Photocatalytic treatment is one of the techniques used for the treatment of dyes-contaminated wastewater. It is important to develop an effective visible-light-driven catalyst for the treatment of dyes-contaminated wastewater. This study reports the synthesis of ZnO-reduced graphene oxide catalyst for the degradation of methylene blue.

We aimed to evaluate the role of selected single nucleotide polymorphisms of DNA damage response pathway genes in breast cancer (BC). In present study, 500 BC patients and 500 controls was used to estimate the frequency of single nucleotide polymorphisms of DNA damage response pathway genes. Tetra-amplification refractory mutation system-PCR technique was used for screening of the six selected polymorphisms.

This study was planned to examine the effects of single nucleotide polymorphism (SNPs) on the risk of thyroid cancer in 499 patients and 500 controls. Three SNPs of gene and three SNPs of gene were analyzed using Tetra-primer ARMS-PCR followed by sequencing. rs121913314 of gene genotype TT showed 32-fold increased risk of thyroid cancer and rs2305994 of genotypes TT and CT showed 2.
