BACKGROUND Cigarette smoking (CS) is the main risk factor for the development of chronic obstructive pulmonary disease (COPD) and most COPD exacerbations are caused by respiratory infections including influenza. Influenza infections are more severe in smokers. The mechanism of the increased risk and severity of infections in smokers is likely multifactorial, but certainly includes changes in im...

let (m,g ) be a compact immersed hypersurface of (rn+1,) , λ1 the first nonzeroeigenvalue, α the mean curvature, ρ the support function, a the shape operator, vol (m ) the volume of m,and s the scalar curvature of m. in this paper, we established some eigenvalue inequalities and proved theabove.1) 1 2 2 2 2m ma dv dvn∫ ρ ≥ ∫ α ρ ,2)( )2 2 1 2m 1 mdv s dvn nα ρ ≥ ρ∫ − ∫ ,3) if the scalar curvatu...

We introduce new combinatorial models called strip bundles for the quantum affine algebra Uq(D4(3)) and give realizations of crystal B(∞) highest weight crystals B(λ) over in terms bundles. In these bundle realizations, B(Λ1) natural representation V(Λ1) finite Uq(G2) plays a crucial role.

The activation of interferon (IFN)-regulatory factor-3 (IRF3), characterized by phosphorylation and nuclear translocation of the latent transcription factor, is central to initiating innate antiviral responses. Whereas much has been learned about the upstream pathways and signaling mechanisms leading to IRF3 activation, how activated IRF3 operates in the nucleus to control transcription of IFNs...

Hepatitis C virus (HCV) actively evades host interferon (IFN) responses but the mechanisms of how it does so are not completely understood. In this study, we present evidence for an HCV factor that contributes to the suppression of retinoic-acid-inducible gene-I (RIG-I)-mediated IFN induction. Expression of frameshift/alternate reading frame protein (F/ARFP) from HCV -2/+1 frame in Huh7 hepatom...

The Cheeger constant, hG, is a measure of expansion within a graph. The classical Cheeger Inequality states: λ1/2 ≤ hG ≤ √ 2λ1 where λ1 is the first nontrivial eigenvalue of the normalized Laplacian matrix. Hence, hG is tightly controlled by λ1 to within a quadratic factor. We give an alternative Cheeger Inequality where we consider the∞-norm of the corresponding eigenvector in addition to λ1. ...

Recognition of viral genetic material takes place via several different receptor systems, such as retinoic acid-inducible gene I-like receptors and TLRs 3, 7, 8, and 9. At present, systematic comparison of the ability of different types of RNAs to induce innate immune responses in human immune cells has been limited. In this study, we generated bacteriophage 6 and influenza A virus-specific ssR...
