Experimental studies were undertaken to compare the vector competence of Culex (Melanoconion) taeniopus Dyar and Knab, Culex (Melanoconion) ocossa Dyar and Knab, and Psorophora confinnis (Lynch Arribalzalga) from Central America for epizootic (IAB) and enzootic (IE) strains of Venezuelan equine encephalitis (VEE) virus. Virus infection and dissemination rates were significantly higher in Cx. ta...

During the 1971 epidemic of Venezuelan equine encephalomyelitis (VEE) in south Texas, 203 suspect VEE cases were evaluated by the Center for Disease Control. Sixty-seven were confirmed as cases of VEE. Laboratory confirmation was accomplished by isolation of VEE virus from a serum specimen taken during the acute illness in 50 (75%) of the confirmed cases. Serological confirmation was obtained i...

Cross-protection between Venezuelan, Eastern, and Western equine encephalomyelitis (VEE, EEE, WEE) viruses was studied in the hamster by using challenge responses and neutralizing antibody titers as indexes of protection. Formalin-inactivated vaccines induced only homologous protection regardless of the sequence of vaccination or the combination of vaccines employed. Use of attenuated VEE vacci...

Experimental studies were undertaken to ascertain the vector potential of North American (Houston and Alsace) and South American (Sao Paulo and Santa Teresa) strains of Aedes albopictus (Skuse) for an epizootic (Trinidad donkey) strain of Venezuelan equine encephalomyelitis (VEE) virus. Infection rates were similar in all four strains of Ae. albopictus tested after ingestion of VEE virus from a...

Venezuelan equine encephalitis (VEE) epidemics and equine epizootics occurred periodically in the Americas from the 1920s until the early 1970s, when the causative viruses, subtypes IAB and IC, were postulated to have become extinct. Recent outbreaks in Columbia and Venezuela have renewed interest in the source of epidemic/epizootic viruses and their mechanism of interepizootic maintenance. We ...

A real binary tensor consists of $2^d$ entries arranged into hypercube format $2^{\times d}$. For $d=2$, a is $2\times 2$ matrix with two singular values. Their product the determinant. We generalize this formula for any $d\ge 2$. Given partition $\mu\vdash d$ and $\mu$-symmetric $t$, we study distance function from $t$ to variety $X_{\mu,\mathbb{R}}$ tensors rank one. The local minima related ...

Studies have suggested that enzootic strains of Venezuelan equine encephalitis (VEE) subtype ID in the Amazon region, Peru, may be less pathogenic to humans than are epizootic variants. Deaths of 2 persons with evidence of acute VEE virus infection indicate that fatal VEEV infection in Peru is likely. Cases may remain underreported.

The generation of human induced pluripotent stem cells (iPSCs) holds great promise for the development of regenerative medicine therapies to treat a wide range of human diseases. However, the generation of iPSCs in the absence of integrative DNA vectors remains problematic. Here, we report a simple, highly reproducible RNA-based iPSC generation approach that utilizes a single, synthetic self-re...

In animals, 14-3-3 proteins bind two cell cycle proteins WEE1 and CDC25 stabilising their phosphorylated state. We report here for the first time interactions between WEE1 and 14-3-3 proteins both in vitro and in vivo in plants. The Arabidopsis 14-3-3 family partitions into either an Epsilon or Non-Epsilon group. In a yeast 2-hybrid screen Arabidopsis WEE1 interacted with the Non-Epsilon group....
