Abstract:
Preconditioning induces ischemic tolerance, which confers robust protection against ischemic damage. We show marked protection with polyinosinic polycytidylic acid (poly-IC) preconditioning in three models of murine ischemia-reperfusion injury. Poly-IC preconditioning induced protection against ischemia modeled in vitro in brain cortical cells and in vivo in models of brain ischemia and renal ischemia. Further, unlike other Toll-like receptor (TLR) ligands, which generally induce significant inflammatory responses, poly-IC elicits only modest systemic inflammation. Results show that poly-IC is

Abstract:
Novel multi-component composites composed of the biodegradable polymer poly(ethylene adipate) (PEA), the water-soluble polymer poly(ethylene oxide) (PEO), poly(vinyl acetate) (PVAc), and a supramolecular-like inclusion complex (IC) made by α-cyclodextrin (α-CD) and poly(ε-caprolactone) (PCL) (coded as PCL–CD–IC) are discussed in this work. The PCL–CD–IC was used to increase the crystallization rate of the miscible PEA/PEO/PVAc ternary blend that crystalized slower than neat PEA. Higher resolution SEM and TEM images displayed that PCL–CD–IC did not assemble notably in the quaternary composites.

Abstract:
Polyinosinic:polycytidylic acid (poly IC), a double-stranded RNA, is an effective adjuvant in vivo. IFN-λs (also termed IL-28/29) are potent immunomodulatory and antiviral cytokines. We demonstrate that poly IC injection in vivo induces large amounts of IFN-λ, which depended on hematopoietic cells and the presence of TLR3 (Toll-like receptor 3), IRF3 (IFN regulatory factor 3), IRF7, IFN-I receptor, Fms-related tyrosine kinase 3 ligand (FL), and IRF8 but not on MyD88 (myeloid differentiation factor 88), Rig-like helicases, or lymphocytes.

Abstract:
Classical swine fever virus (CSFV) is capable of counteracting innate cellular antiviral responses by inhibiting type I interferon (IFN)-α/β induction. A function associated with CSFV Npro, with respect to the inhibition of IFN-β production, has been clearly elucidated. In this study, we explored the role of CSFV Ernsin IFN-β induction by exogenous double-stranded (ds) RNA. Synthetic dsRNA (poly (IC)) was used as an exogenous stimulus to trigger IFN-β induction. CSFV Ernsinhibited IFN-β promoter-driven luciferase activity induced by poly (IC) in different cell lines, and the inhibitory effect

ABSTRACT Classical swine fever virus (CSFV) replicates efficiently in cell lines and monocytic cells, including macrophages (MΦ), without causing a cytopathic effect or inducing interferon (IFN) secretion. In the present study, the capacity of CSFV to interfere with cellular antiviral activity was investigated. When the porcine kidney cell line SK-6 was infected with CSFV, there was a 100-fold increased capacity to resist to apoptosis induced by polyinosinic-polycytidylic acid [poly(IC)], a synthetic double-stranded RNA. In MΦ, the virus infection inhibited poly(IC)-induced alpha/beta IFN (typ

Relative to several other toll-like receptor (TLR) agonists, we found polyinosinic:polycytidylic acid (poly IC) to be the most effective adjuvant for Th1 CD4+ T cell responses to a dendritic cell (DC)–targeted HIV gag protein vaccine in mice. To identify mechanisms for adjuvant action in the intact animal and the polyclonal T cell repertoire, we found poly IC to be the most effective inducer of type I interferon (IFN), which was produced by DEC-205+ DCs, monocytes, and stromal cells.

Type I IFNs modulate the onset of immune responses against viruses through the activation of numerous rapid signaling pathways. Although beneficial on specific infected cells, administered IFNs were shown to decrease thymic cellularity. Herein, we developed a murine model treated with polyinosinic:polycytidylic acid (Poly IC) to dissect the mechanisms and the role of in vivo produced IFNs on the thymus. Treatment induced thymic atrophy, while having no effect on the lymph nodes. However, under chronic conditions, we observed a complete thymic replenishment. These findings should be the result

Abstract The lock-in phase mapping technique with modulated reflectance is introduced for the first time. With its help, the modulated reflectance mechanisms using thermal laser in operating FETs, particularly in the pinch off region, are clarified. The free carrier absorption mechanism dominates at a high modulation frequency, while thermo-reflectance mechanisms at a low modulation frequency. In the pinch-off region, thermo-reflectance mechanism cannot be neglected due to extremely low free carrier concentration.

Abstract:
Quantifying the contribution of the hot carrier effect (HCE) and the negative bias temperature instability (NBTI) effect in PMOSFET device reliability is an urgent target, especially as the dual poly-gate implantation and the novel oxide growth recipe is derived. At this stage, the PMOS gate-oxide thickness is thinner than before, therefore, the implanted boron or BF2 is possible to penetrate from poly gate to surface channel. Furthermore, the implant source contains the plenty ionized hydrogen. This material is easily to be trapped in the gate oxide or bonded with the surface-channel silicon.
