[Abstract] This paper presents a novel DNA sequences alignment method based on inverted index. Now most large scale information retrieval system are all use inverted index as the basic data structure. But its application in DNA sequence alignment is still not found. This paper just discuss such applications. Three main problems, DNA segmenting, long DNA query search, DNA search ranking algorith...

Background: One of the major factors affecting on male infertility is oxidative stress (OS). Two main sources of ROS production are leukocytes and spermatozoa. The ROS such as tertiary-butyl hydroperoxide (TBHP) may damage and fragmentate to sperm DNA, which can lead to complications in the offspring. In this study, we will investigate the effect of od on DNA fragmentation index (DFI) in sperm ...

In this Russell Research Report, we explore the potential for replication in the context of the evolution of the hedge fund industry and the investment industry as a whole. Our key theme is the importance of alternative beta indexes, both for replication and as benchmarks for the hedge fund industry. With the term alternative beta, we refer to systematic factors beyond those that can today be t...

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 ...

PURPOSE Aberrations of circulating nucleic acid integrity have been observed in cancer patients. However, the clinical significance of such changes has not been completely elucidated. In this study, we investigated the plasma DNA integrity in nasopharyngeal carcinoma (NPC) patients and its association with patients' survival after radiotherapy. EXPERIMENTAL DESIGN Plasma DNA integrity was ana...

ABSTRACT A precise real-time polymerase chain reaction (PCR) assay was developed for quantifying Verticillium albo-atrum DNA. The assay was used in a repeated experiment to examine the relationship between the quantity of pathogen DNA detected in infected leaves and shoots and the severity of Verticillium wilt symptoms in several alfalfa cultivars expressing a range of disease symptoms. Plants ...

The aim of the study was to assess, in a group of nonselected patients with neuroblastoma, the prognostic value of both N-myc gene amplification and DNA ploidy index, taking into account potential confounding factors such as age and stage. Of 59 patients studied, 23 were younger than 1 year at diagnosis, 31 presented with stage IV, 10 with stage III, 5 with stage II, 8 with stage I, and 4 with ...
