| The paper deals with the formal speciication of a general-purpose multimedia synchronization mechanism, known as the conditional delivery mechanism capable of addressing both intra-and inter-stream synchronization issues. The proposed mechanism, initially introduced in 3, 11], is based on the identiication of causal relations among information units of one or several streams and has the purpo...

MicroRNA (miRNA) detection by reverse transcription (RT) quantitative real-time PCR (RT-qPCR) is the most popular method currently used to measure miRNA expression. Although the majority of miRNA families are constituted of several 3'-end length variants ("isomiRs"), little attention has been paid to their differential detection by RT-qPCR. However, recent evidence indicates that 3'-end miRNA i...

to investigate the influence of hypoxia during the early stage of incubation on embryonic developmentand hatching events, and consequently on incidence of ascites in broiler chickens, one thousand fertile eggswere incubated in two commercial incubators. half the eggs were incubated in a low altitude incubator untilhatched. the second half were incubated in a high altitude incubator until day 10...

knowledge of virus and replication kinetic is one of the most important issues in the vaccine production. the present study aimed to evaluate the best harvesting time of h9n2 avian influenza virus (aiv) vaccine strain inoculated in specific pathogen free (spf) embryonated chicken eggs (ece)s. for this purpose, 10-5 dilution of aiv (a/chicken/iran/99/h9n2) was inoculated into 336, 11-day old ece...

West Nile virus (Flaviviridae: Flavivirus) is a serious infectious disease that recently spread across the North America continent. A spatial analysis tool was developed on the ArcMap 9.x platform to estimate potential West Nile virus activity using a spatially explicit degree-day model. The model identifies when the virus Extrinsic Incubation Period (EIP) is completed within the vector longevi...
