Background: Super-paramagnetic annexin-V conjugated micro-beads are able to eliminate sperm with phosphatidylserine externalization (PSE). PSE is considered as apoptotic sperm. PES positive sperm can be removed from sperm preparations sample to enhance sperm quality for assisted medical procreation. Therefore, the efficiency of this technique over normal sperm processing procedure such as densi...

Background: Selection of human spermatozoa prior to assisted reproduction is currently based on motility and morphology. Recently, Zeta method has been introduced for normal sperm selection based on sperm surface charges. In addition, one of the features of apoptosis is the externalization of phosphatidylserine (PS), which are normally present on the inner leaflet of the sperm plasma membrane. ...

The significance of discontinuous gas-exchange cycles (DGC) in reducing respiratory water loss (RWL) in insects is contentious. Results from single-species studies are equivocal in their support of the classic 'hygric hypothesis' for the evolution of DGC, whereas comparative analyses generally support a link between DGC and water balance. In this study, we investigated DGC prevalence and charac...

The adaptive significance of discontinuous gas exchange cycles (DGC) in insects is contentious. Based on observations of DGC occurrence in insects of typically large brain size and often socially-complex life history, and spontaneous DGC in decapitated insects, the neural hypothesis for the evolution of DGC was recently proposed. It posits that DGC is a non-adaptive consequence of adaptive down...

Mutations in genes encoding components of the sarcolemmal dystrophin-glycoprotein complex (DGC) are responsible for a large number of muscular dystrophies. As such, molecular dissection of the DGC is expected to both reveal pathological mechanisms, and provides a biological framework for validating new DGC components. Establishment of the molecular composition of plasma-membrane protein complex...

Although discontinuous gas exchange cycles (DGC) are known from many insects, the effects of body size and temperature on DGC have not been widely examined. Here, these effects are investigated in five Scarabaeus dung beetle species from mesic and xeric habitats. The investigation tests two hypotheses: that previous estimates of the scaling exponents for the DGC and its characteristics are more...

To compare the gene expression profiling between intestinal-type gastric cancer (IGC) and diffuse-type gastric cancer (DGC), cDNA microarray containing 7334 gene elements was performed on 12 paired IGC specimens/its' normal epithelial tissue and 11 paired DGC specimens/its' normal epithelial tissue. Twenty-seven genes were co-overexpressed in IGC and DGC. These overexpressed genes were related ...

DEFINITION Distributed Geospatial Computing (DGC) refers to the geospatial computing resides on multiple computers connected through computer networks. Figure 1 illustrates DGC within the C/S architecture [1]: where the geospatial computing is conducted by the geospatial components, which can communicate with each other or communicate through wrapping applications, such as web server and web br...

Direct ground cooling (DGC) is a method used in cold climates to provide buildings without the use of any mechanical refrigeration. When DGC utilized for providing cooling, ground-source heat pumps (GSHPs) and district heating (DH) are two commonly technologies buildings. This article investigates coupling with GSHPs DH terms purchased energy lifecycle costs. An office building equipped active ...

OBJECTIVE This study was carried out to investigate the correlations of the sperm DNA fragmentation index (DFI) with semen parameters and apoptosis, and to investigate the effects of density-gradient centrifugation (DGC) and magnetic-activated cell sorting (MACS) on reducing the proportion of sperm with DNA fragmentation and protamine deficiency. METHODS Semen analysis and a sperm DNA fragmen...
