BACKGROUND This study aimed to establish an effective prognostic nomogram with or without plasma Epstein-Barr virus DNA (EBV DNA) for nondisseminated nasopharyngeal carcinoma (NPC). METHODS The nomogram was based on a retrospective study of 4630 patients who underwent radiotherapy with or without chemotherapy at Sun Yat-sen University Cancer Center from 2007 to 2009. The predictive accuracy a...

A number of studies have shown that the DNA-ploidy of mononucleated blood cells is a prognostic factor of acute lymphoblastic leukaemia in childhood, patients with an hyperploid DNA index showing a significantly better response to chemotherapy than those with a euploid DNA index. The aim of the present study was to re-evaluate this question for a subset of patients in the German-Austrian-Swiss ...

Background: To establish importance of sperm DNA assessment in resolving the unexplained infertility problem. Materials and Methods: This article is based on the careful observation of texts and papers from 2000-2014 about the DNA damage assessment as a significant parameter of sperm function test. Results: Acidic Aniline blue, Sperm Chromatin Dispersion test(SCD), Malondialdehyde concentration...

The tumor growth fraction measured by the percentage labeled mitoses method has been determined in transplantable solid and ascites murine tumors, the latter being measured at different times after transplantation. These values were compared to an in vitro, autoradiographic assay that determines the fraction of cells in a given population (primer-available DNA-dependent DNA polymerase index) th...

Cellular DNA content is a discriminator of cell cycle stage and ploidy. Using pepsin digestion for cell disper sal, a combination of ethidium bromide and mithramycin for DNA fluorochromation, and a new sheath flow cham ber in a PHYWE ICP-11 pulse cytophotometer, we ob tained DNA histograms with high resolution (coefficient of variation, 2.0 to 7.0; mean, 3.3%) on biopsy samples of solid tumors....

introduction: the amount of expression of bax and bcl-2 genes in infertile men’s sperm as well as its association with sperm parameters and dna fragmentation index is an issue which has not been studied yet. in this research, it is assumed that up-regulation of bax and downregulation of bcl-2 are directly associated with sperm dna fragmentation. methods: after obtaining semen samples from the p...

BACKGROUND Bacterial infections in the genital tract frequently result in morbidity through a variety of inflammation based symptoms. One component of the bacteria that may trigger host inflammatory response is their DNA. CpG motifs in this DNA are known targets for Toll-like receptor 9 (TLR9), which is a pathogen-recognition receptors focusing on CpG DNA. The activation of TLR9 induces the NF-...

This case-control study examined whether DNA aneuploidy in colorectal adenomas is a risk factor for subsequent ademona recurrence. Cases (recurrent polyp formers) were defined as persons with diagnoses of new adenomas at 2 colonoscopies following the index (first) adenoma diagnosis; controls were persons with no new adenomas at a follow-up at least 1 year after the index diagnosis. Cases (n = 2...
