The study of the medically important polyomavirus JC virus is limited to only a few laboratories, primarily because the permissive cell system most often used, primary human fetal glial cells, is difficult to obtain and propagate. We have introduced mutations at the origin of DNA replication of JC virus and transformed glial cells with the replication-defective genomes. Although normal glial ce...

Many variables control the critical current density (Jc ) in BSCCO-2223 composites but not all of them are yet well understood, or even positively identified. One important factor is reported to be the density of the BSCCO filament, as measured by microhardness. Since different deformation processes may be used during fabrication, and each can have a different effect on the final BSCCO core den...

In this paper, we have proposed a q-deformed Jaynes-Cummings(JC) model and constructed the q-SuperCoherent States(q-SCSs) for the q-deformed JC model. We have also discussed the properties of the qsupercoherent states and given the completeness relation expression. The representation of the q-supercoherent states for the q-deformed JC model is studied as well. PACS number(s): 03.65.Nk Key Works...

The main purpose of this note is to present a new approach to Poisson Approximations. Some bounds in Poisson Approximations in term of classical Le Cam’s inequalities for various row-wise triangular arrays of independent Poisson-binomial distributed random variables are established via probability distances based on Trotter-Renyi operators. Some analogous results related to random sums in Poiss...

Background and Aims: The role of BK and JC polyomaviruses (BKV and JCV) in the causation of respiratory disease and the natural route of transmission has not well been established. The aim of study was to determine the prevalence of BK and JC viruses in 280 respiratory samples and evaluate their contribution to respiratory disease. Materials and Methods: PCR was used to screen specimens for BK...

JC and BK human polyomaviruses (family Polyomaviridae) may cause severe neurological or urinary tract pathologies in immunocompromised hosts. In the present study, we evaluated a new commercially available PCR and microplate colorimetric hybridization assay for the standardized differential detection of JC virus (JCV) and BK virus (BKV) genomes in clinical samples. This JC/BK Consensus test was...

BACKGROUND Infection with JC virus has been proposed as a risk factor for colorectal cancer. A nested case-control study was conducted to evaluate the association between prediagnostic JC virus antibodies and the risk of incident colorectal cancer and adenomas. METHODS Two research serum banks were established in Washington County, MD in 1974 and 1989, with the collection of blood samples fro...

BACKGROUND AND PURPOSE The Joint Commission (JC) began certifying Primary Stroke Centers in November 2003. Cross-sectional studies assessing the impact of certification could be biased if these centers had better outcomes before the start of the program. We determined whether hospitals certified within the first years of the JC program had better outcomes than noncertified hospitals before the ...
