Emerging applications like electronic commerce and secure communications over open networks have made clear the fundamental role of public key cryptography as a unique enabler for worldwide scale security solutions. On the other hand, these solutions clearly expose the fact that the protection of private keys is a security bottleneck in these sensitive applications. This problem is further wors...

In 2011-2012, sixty nine samples were collected from alfalfa plants showing viral infection symptoms in Riyadh region. Mechanical inoculation with sap prepared from two collected samples out of twenty five possitive for Alfalfa mosaic virus (AMV) by ELISA were produced systemic mosaic on Vigna unguiculata and Nicotiana tabacum, local lesion on Chenopodium amaranticolor and C. quinoa. Vicia faba...

BACKGROUND AND PURPOSE Due to its sensitivity to deoxyhemoglobin, susceptibility weighted imaging (SWI) enables the visualization of deep medullary veins (DMV) in patients with acute stroke, which are difficult to depict under physiological circumstances. This study assesses the asymmetric appearance of prominent DMV as an independent predictor for stroke severity and outcome. MATERIALS AND M...

An unusual and distinguishing feature of alfalfa mosaic virus (AMV) and ilarviruses such as tobacco streak virus (TSV) is that the viral coat protein is required to activate the early stages of viral RNA replication, a phenomenon known as genome activation. AMV-TSV coat protein homology is limited; however, they are functionally interchangeable in activating virus replication. For example, TSV ...

More than 90% of 3-week-old clones obtained from avian myeloblastosis virus (AMV)-induced myeloblasts differenti ate into mature cells when grown as colonies in semisolid medium. This was determined primarily by assaying colo nies on resistant cell feeder layers for the presence of myeloblasts. These colonies were also seeded onto suscepti ble cell feeder layers to assay for the presence of tra...

RNA sequence relatedness among avian RNA tumor virus genomes was analyzed by inhibition of DNA-RNA hybrid formation between 3H-labeled 35S viral RNA and an excess of leukemic or normal chicken cell DNA with increasing concentrations of unlabeled 35S viral RNA. The avian viruses tested were Rous associated virus (RAV)-3, avian myeloblastosis virus (AMV), RAV-60, RAV-61, and B-77 sarcoma virus. H...

This research assesses the influences of Atlantic Multidecadal Variability (AMV) on global tropical cyclones (TCs) using two large ensembles idealized climate model simulations with opposite signs AMV forcings superimposed (i.e., AMV+ and AMV–). We first detect TCs then compare TC activity by basin in experiments. find contrasting responses Pacific frequency to anomalies. Compared AMV–, signifi...

In contrast to most alfalfa mosaic virus (AMV) strains (YSMV, S, M and 425), AMV strains VRU and 1 5/64 can form abnormally long virus particles, an ability which has been linked to the coat protein (CP). In order to study this phenomenon, the CP-encoding RNAs 3 of AMV strains VRU and 1 5/64 were cloned and fully sequenced. Comparative sequence analyses of AMV RNA 3 sequences derived from diffe...

The defective acute leukemia viruses avian myeloblastosis virus (AMV) and E26 virus each contain an inserted cellular sequence related to the same highly conserved cellular gene, proto-amv. The oncogenes of these two retroviruses differ from this cellular proto-oncogene in gene structure, transcript structure, and gene product. The product of the AMV oncogene (myb) is a 48,000 Mr protein, p48my...

Accessory mitral valve (AMV) is a rare congenital cardiac anomaly that has been reported in 1 in 26,000 people in an echocardiography series. Most cases of AMV are associated with other cardiac abnormalities. Although patients with AMV are usually asymptomatic, syncope, exercise intolerance, and chest pain are described in patients with left ventricular outflow (LVOT) obstruction. Here we prese...
