BACKGROUND Early outbreaks of the pandemic influenza A (H1N1) 2009 virus predominantly involved young children, who fuelled transmission through spread in homes and schools. Seroprevalence studies conducted on stored serum collections indicated low levels of antibody to the novel strain in this age group, leading many to recommend priority immunisation of paediatric populations. OBJECTIVES In...
This paper examines reading as done by programmers engaged in software development. Reading is an activity we feel should be of fundamental interest to studies of programming, but the practical achievement of which has not been closely examined. We give examples of programmers reading in pairs, and reading alone, and show reading in both cases to be explainable in terms of shared social practic...
Abstract Background H7 subtype avian influenza has caused great concern in the global poultry industry and public health. The conventional serological subtype-specific diagnostics is implemented by hemagglutination inhibition (HI) assay despite lengthy operation time. In this study, an efficient, rapid high-throughput competitive enzyme-linked immunosorbent (cELISA) was developed for detection ...
BACKGROUND & AIMS Foxp3(+) T-regulatory cells (Tregs) maintain intestinal homeostasis under conditions of continuous challenge with inflammatory microbes. However, plasticity of the Treg population under certain conditions has been reported; Foxp3(+) Tregs can be converted to Foxp3(-) CD4(+) T cells. METHODS We used mice with a T cell-induced colitis model to study the regulatory role of type...
BACKGROUND The direct effect of antigenic site mutations in influenza viruses on antigenic drift and vaccine effectiveness is poorly understood. OBJECTIVE To investigate the genetic and antigenic characteristics of human influenza A (H3N2) viruses circulating in Ontario during the early 2010-2011 winter season. STUDY DESIGN We sequenced the hemagglutinin (HA) and neuraminidase (NA) genes fr...
Mitotic recombination is a process involved in carcinogenesis which can lead to genetic loss through the loss of heterozygosity. The recombinogenic potentials of two anticancer drugs topoisomerase I inhibitors, camptothecin (CPT) and irinotecan (CPT-11), were evaluated in the present study. The homozygotization assay, which assess the induction of mitotic recombination and gene homozygosis, as ...
Serum specimens were collected from 125 pigs on Miyako Island, 112 pigs on Ishigaki Island, and 42 pigs on Kume Island from 2005 to 2007, and 54 pigs on Yonaguni Island from 2006 to 2007. Their sera were tested for Japanese encephalitis virus (JEV) antibody by hemagglutination inhibition (HI) assay. Five serum samples (4.5%) from Ishigaki Island were positive for HI antibody, and 4 of the 5 sam...
An understanding of common human diversity in innate immune pathways should be beneficial in understanding autoimmune diseases, susceptibility to infection, and choices of anti-inflammatory treatment. Such understanding could also result in definition of currently unknown components of human inflammation pathways. A cellular genome-wide association studies (GWAS) platform, termed Hi-HOST (High-...
BACKGROUND Health insurance (HI) plays an important role in ensuring the financial equity by the risk pooling mechanism and reducing the economic burden of healthcare for HIV/AIDS patients. However, there is a lack of evidence to clearly understand HI coverage in regard to people living with HIV (PLWH). We conducted this study to explore the coverage and barriers of HI among PLWH in Vietnam. ...
we have measured the competitive antagonistic effect of chlorpheniramine in bronchi of 8 normal and 12 asthmatic subjects. classical pharmacological theory states that the degree of competitive antagonism depends only upon 1) antagonist concentration at the receptor, and 2) receptor affinity. delivery and affinity also influence agonist responsiveness, but measurement of bronchial antagonism al...
