UNLABELLED Through its interaction with the 5' translation initiation factor eIF4G, poly(A) binding protein (PABP) facilitates the translation of 5'-capped and 3'-poly(A)-tailed mRNAs. Rotavirus mRNAs are capped but not polyadenylated, instead terminating in a 3' GACC motif that is recognized by the viral protein NSP3, which competes with PABP for eIF4G binding. Upon rotavirus infection, viral,...

The suitability of white-tailed deer (Odocoileus virginianus) as hosts for the cattle ticks Rhipicephalus (Boophilus) microplus and Rhipicephalus (Boophilus) annulatus, has been well documented. These ticks have a wide host range, and both transmit Babesia bovis and Babesia bigemina, the agents responsible for bovine babesiosis. Although this disease and its vectors have been eradicated from th...

Habitat fragmentation and urbanization not only cause extirpation of species, but also alter the behaviour of species in human modified areas. We evaluated behavioural characteristics of the black-tailed prairie dog (Cynomys ludovicianus), a keystone species, in the urban landscape of Denver, CO, USA. Specifically, we investigated the proportion of vigilance, foraging, and social behaviour with...

Transfusion of blood from a simian immunodeficiency virus (SIV)- and simian T-cell lymphotropic virus-infected sooty mangabey (designated FGb) to rhesus and pig-tailed macaques resulted in the development of neurologic disease in addition to AIDS. To investigate the role of SIV in neurologic disease, virus was isolated from a lymph node of a pig-tailed macaque (designated PGm) and the cerebrosp...

In order to better understand the evolution of cognitive abilities in primates, information on cognitive traits of the most basal living primates can provide important comparative baseline data. Compared to haplorhine primates, lemurs have relatively smaller brains and reduced abilities to solve problems in the technical and social domain. However, recent studies have suggested that some cognit...

Economic losses due to infection with Bovine viral diarrhea virus (BVDV) have prompted introduction of organized control programs. These programs primarily focus on the removal of persistently infected (PI) animals, the main source of BVDV transmission. Recently, persistent BVDV infection was demonstrated experimentally in white-tailed deer, the most abundant wild ruminant in North America. Con...

Although heavy-tailed fluctuations are ubiquitous in complex systems, a good understanding of the mechanisms that generate them is still lacking. Optical complex systems are ideal candidates for investigating heavy-tailed fluctuations, as they allow recording large datasets under controllable experimental conditions. A dynamical regime that has attracted a lot of attention over the years is the...

Sympatric populations of phylogenetically related species are often vulnerable to similar communicable diseases. Although some host populations may exhibit spatial structure, other hosts within the community may have unstructured populations. Thus, individuals from unstructured host populations may act as interspecific vectors among discrete subpopulations of sympatric alternate hosts. We used ...

background: when male animals die, spermatozoa within the body of animal will be degenerated. because of unique chromatin structure of sperm, maybe this degeneration is different from other cells. however there is not any research which considered directly the integrity of sperm dna by keeping the cadaver in refrigerator. objective: the aim of this study was to assess viability, total motility ...

This paper develops an empirical profile of BGP prefix announcements that originate from multiple ASes, so-called MOAS announcements. Analysis of Oregon RouteViews data over one year shows that a small fraction of prefixes are responsible for a very large fraction of all origin AS transitions observed at RouteViews. Moreover, these heavy-hitter prefixes oscillated between two origin ASes. The p...
