AIM The aim of this prospective study was to find possible relationship between ROS production measured by chemiluminescence and flow cytometry in human semen and sperm DNA damage estimated by Sperm Chromatin Structure Assay. METHODS Study included 39 men from infertile couples and 23 fertile volunteers who served as a control group. Aliquot of neat semen was used for ROS detection by chemilu...

Searching patterns in the DNA sequence is an important step in biological research. To speed up the search process, one can index the DNA sequence. However, classical indexing data structures like suffix trees and suffix arrays are not feasible for indexing DNA sequences due to main memory requirement, as DNA sequences can be very long. In this paper, we evaluate the performance of two compress...

Background & Aims: Gastric cancer is the second common cancer in Iran and it has unfortunately no diagnostic signs in early stages. Considering the role of genetic and environmental factors in the development of gastric cancer, this study aimed at evaluating DNA-content of stomach cells in patients with gastric cancer in order to find a reliable index for prediction of disease prognosis and pro...

N-type macroporous silicon microcavity structures were prepared using electrochemical etching in an HF solution in the absence of light and oxidants. The CdSe/ZnS water-soluble quantum dot-labeled DNA target molecules were detected by monitoring the microcavity reflectance spectrum, which was characterized by the reflectance spectrum defect state position shift resulting from changes to the str...
