The serine-threonine mitogen-activated protein kinase kinase family member T-LAK cell-originated protein kinase (TOPK/PBK) is heavily involved in tumor development, cancer growth, apoptosis, and inflammation. Despite the identification of TOPK as a promising novel therapeutic target, no inhibitor of TOPK has yet been reported. In this study, we screened 36 drug candidates using an in vitro kina...

A competitive enzyme-linked immunosorbent assay (C-ELISA) using a baculovirus-expressed recombinant nucleocapsid protein antigen (rNDV-N) and an rNDV-N-specific monoclonal antibody (5B3) was developed for the detection of Newcastle disease virus (NDV) antibodies, and its diagnostic performance was evaluated. The specificity and sensitivity of the C-ELISA was found to be 98.4 and 98.9%, respecti...

BACKGROUND Antigenic characterization of influenza viruses is typically based on hemagglutination inhibition (HI) assay data for viral isolates tested against strain-specific postinfection ferret antisera. Here, similar virus characterizations were performed using serological data from humans with primary influenza A(H3N2) infection. METHODS We screened sera collected between 1995 and 2011 fr...

OBJECTIVES Hemagglutination inhibiting (HI) antibodies correlate with influenza vaccine protection but their association with protection induced by natural infection has received less attention and was studied here. METHODS 940 people from 270 unvaccinated households participated in active ILI surveillance spanning 3 influenza seasons. At least 494 provided paired blood samples spanning each ...

Received: June 26 2017; Accepted: July 13 2017; Published: July 17 2017 challenge studies in healthy adults with potentially attenuated viruses? Second, influenza vaccines are recommended not only for healthy adults but also for children, the elderly, pregnant women, anyone with high-risk conditions and those with chronic medical conditions; it is not known whether the HI titer of 40 is equally...

BACKGROUND AND PURPOSE Human growth and transformation-dependent protein (HGTD-P) is a new proapoptotic protein and an effector of cell death induced by hypoxia-ischemia (HI). The function of HGTD-P has been investigated in human prostate cancer cells and mouse neurons cultured in vitro. However, whether HGTD-P is involved in regulating the apoptosis of rat neurons is not clear, and the relevan...

Perinatal hypoxia-ischemia (HI) results in brain injury, whereas mild hypoxic episodes result in preconditioning, which can significantly reduce the vulnerability of the brain to subsequent severe hypoxia-ischemia. Hypoxic-preconditioning (PC) has been shown to enhance cell survival and differentiation of progenitor cells in the central nervous system (CNS). The purpose of this study was to det...

From May to December 1997, 18 cases of mild to severe respiratory illness caused by avian influenza A (H5N1) viruses were identified in Hong Kong. The emergence of an avian virus in the human population prompted an epidemiological investigation to determine the extent of human-to-human transmission of the virus and risk factors associated with infection. The hemagglutination inhibition (HI) ass...

Background Long-term persistence of immune response and safety of two doses of an A/California/07/2009 H1N1 pandemic influenza vaccine adjuvanted with AS03 (an α-tocopherol oil-in-water emulsion-based Adjuvant System) administered 21 d apart was evaluated in Japanese adults [NCT00989612]. Methods One-hundred healthy subjects aged 20-64 y (stratified [1:1] into two age strata 20-40 y and 41-...
