Allergic asthma is characterized by airway inflammation initiated by adaptive immune responses to aeroallergens. Recent data suggest that severe asthma may be a different form of asthma rather than an increase in asthma symptoms and that innate immune responses to LPS can modulate adaptive immune responses to allergens. In this study, we evaluated the(More)
BACKGROUND Although respiratory viral infections in early childhood can enhance the development of airway allergen sensitization, the exact mechanisms of the effects of viral infections on the adaptive immune response to inhaled allergens are controversial. OBJECTIVE We sought to evaluate the effects of double-stranded RNA (dsRNA) on airway sensitization(More)
BACKGROUND Although catheter ablation is an effective rhythm control strategy for atrial fibrillation (AF), empirically-based ablation has a substantial recurrence rate. The purposes of this study were to develop a computational platform for patient-specific virtual AF ablation and to compare the anti-fibrillatory effects of 5 different virtual ablation(More)
Eosinophils have been reported to modulate T cell responses. Previously, we reported that high-mobility group box 1 protein (HMGB1) played a key role in the pathogenesis of asthma. This study was conducted to test our hypothesis that eosinophils could modulate T cell responses via HMGB1 in the pathogenesis of asthma characterized by eosinophilic airway(More)
Deguelin is a rotenoid isolated from several plant species, which has been reported to have chemopreventive effects in skin, mammary, colon and lung cancers. The effects of deguelin on the proliferation and apoptosis of hepatic cancer cells were assessed by MTT assay and flow cytometric analysis. The growth of hepatic cancer cells (HepG2, Huh7 and SK-Hep1)(More)
Retinal vascular damages are the cardinal hallmarks of retinopathy of prematurity (ROP), a leading cause of vision impairment and blindness in childhood. Both angiogenesis and vasculogenesis are disrupted in the hyperoxia-induced vaso-obliteration phase, and recapitulated, although aberrantly, in the subsequent ischemia-induced neovessel formation phase of(More)
Lamotrigine is a recent medication which is prescribed for various neuropsychiatric conditions. It is generally well-tolerated, but recent pharmacoepidemiological evidence suggests that lamotrigine is associated with risks of developing severe cutaneous drug reactions like toxic epidermal necrolysis (TEN). However, there still remains the diagnostic(More)
We report the real-time, label-free and electrical detection of vascular endotherial growth factor (VEGF) for cancer diagnosis using anti-VEGF aptamer-modified Si nanowire field-effect transistors (SiNW-FETs). Specifically, the high quality single-crystalline SiNWs of both n-type and p-type characters were surface modified with the covalent immobilization(More)
Potent endogenous protection from ischemia can be induced in the retina by ischemic preconditioning (IPC). Protein kinase B/Akt is a cellular survival factor. We hypothesized that Akt was integral to IPC based upon differential effects of Akt subtypes. Rats were subjected to retinal ischemia after IPC or IPC-mimicking by the opening of mitochondrial KATP(More)
PURPOSE Sputum eosinophilia is observed frequently in patients with rhinitis. Sputum eosinophilia in patients with non-asthmatic allergic rhinitis has been suggested to be related to nonspecific airway hyperresponsiveness (AHR). However, the clinical significance of sputum eosinophilia in patients with non-asthmatic rhinitis without AHR has not been(More)
