OBJECTIVE To examine the relationship between sperm chromatin defects, evaluated by sperm chromatin structure assay (SCSA) and semen characteristics in cryopreserved semen specimens from patients diagnosed with various types of cancer. DESIGN Prospective study. SETTING Andrology laboratory at a tertiary care hospital. PATIENT(S) Cryopreserved semen samples from 12 healthy fertile men and ...

Sperm DNA damage is prevalent among infertile men and is known to influence natural reproduction. However, the impact of sperm DNA damage on assisted reproduction outcomes remains controversial. Here, we conducted a meta-analysis of studies on sperm DNA damage (assessed by SCSA, TUNEL, SCD, or Comet assay) and clinical pregnancy after IVF and/or ICSI treatment from MEDLINE, EMBASE, and PUBMED d...

Spectrum auction is an enabling approach for drastically improving the spectrum utilization to satisfy the ever increasing service demands in wireless networks. However, the back-room dealing (i.e., the frauds of the untrustworthy auctioneer and the bid-rigging between the greedy bidders and the insincere auctioneer) makes these applications confront significant security challenges, and fails a...

The sperm chromatin structure assay (SCSA) is a flow cytometric (FCM) technique which exploits the metachromatic properties of Acridine Orange to monitor the susceptibility of sperm chromatin DNA to in-situ acid denaturation. SCSA was used to study the chromatin structure variations of human spermatozoa in semen, both before and after swim-up and after cryopreservation. Semen samples were provi...

Diagnosis of male infertility has mainly been based on the World Health Organization (WHO) manual-based semen parameter's concentration, motility and morphology. It has, however, become apparent that none of these parameters are reliable markers for evaluation of the fertility potential of a couple. A search for better markers has led to an increased focus on sperm chromatin integrity testing i...

BACKGROUND Persistent organochlorine pollutants (POP), such as polychlorinated biphenyls (PCB) and dichlorodiphenyldichloroethylene (p, p'-DDE), are widely found in the environment and considered potential endocrine-disrupting compounds (EDC). Their impact on male fertility is still unknown. METHODS To explore the hypothesis that POP is associated with altered sperm chromatin integrity, a cro...

This paper provides a clusterhead review of clusterhead selection algorithm in Mobile Ad Hoc Networks (MANETs) and proposes a Stable Clusterhead Selection Algorithm for ad hoc networks (SCSA). The algorithm constructs a stable clusterhead with the help of reducing the number of clusterhead reconstruction. It selects the nodes which have the stability to be the clusterheaders. The results of sim...

The aim of this study was to analyse semen quality parameters fresh-extended porcine imported from Denmark through prolonged importing regulations and transport fertility performance in sows inseminated four days post collection. Semen analysed immediately upon the arrival (4 collection) using computer-assisted sperm analyses (CASA), cytomorphology flow cytometry, were later same day. mean conc...

In this study 60 couples undergoing intracytoplasmic sperm injection (ICSI) procedures were enrolled. All men were classified into two groups regarding to the DNA fractionation index (DFI) threshold value: group I < 15% and group II =or> 15%. In group I, median DFI was 4%, normal pre-implantation embryo development was observed and eleven pregnancies were achieved. In group II, median DFI was 2...
