We developed and evaluated a multiplex branched DNA assay for the detection and subtyping of avian influenza (AI) virus strains. The assay successfully detected all 94 AI virus strains of 15 different hemagglutinin (HA) subtypes tested while simultaneously differentiating 24 North American H5, 11 Eurasian H5, and 11 H7 strains. Our study demonstrates for the first time that a branched DNA metho...

The H4-H5 loop of the alpha-subunit of mouse brain Na,K-ATPase was expressed and isolated from Escherichia coli cells. Using fluorescence analogues of ATP, this loop was shown to retain its capability to bind ATP. Isolation of a soluble H4-H5 loop with the native ATP binding site is a crucial step for detailed studies of the molecular mechanism of ATP binding and utilisation.

For the binary response model, we determine optimal designs based on the D-optimal criterion which are robust with respect to misspecifications of the unknown parameters. We propose a maximin approach and provide a numerical method to identify the best two point designs for the commonly applied link functions. This method is broadly applicable and can be extended to designs with a given number ...

The B7/CD28 family has profound modulatory effects in immune responses and constitutes an important target for the development of novel therapeutic drugs against human diseases. Here we describe a new CD28 homologue (CD28H) that has unique functions in the regulation of the human immune response and is absent in mice. CD28H is constitutively expressed on all naive T cells. Repetitive antigenic ...

Due to concerns that high pathogenicity avian influenza would enter into the United States, an interagency strategic plan was developed to conduct surveillance in wild birds in order to address one of the possible pathways of entry. The USDA and state wildlife agencies participated in this effort by collecting samples from 145,055 wild birds from April 2006 through March 2008 in all 50 states. ...

Since 1996, highly pathogenic avian influenza (HPAI) H5N1 virus has presented a persistent threat to public health. Its high degree of genetic diversity also poses enormous challenges in developing effective vaccines. To search for vaccine regimens that could elicit broadly neutralizing antibody responses against diverse HPAI H5N1 strains, in the present study we tested H5 hemagglutinin (HA) fr...

Energy dispersive X-ray spectroscopy microanalysis (EDX), scanning electron microscopy (SEM), and Archimedes' Principle were used to determine the characteristics of inorganic filler particles in five dental alginates, including Cavex ColorChange (C), Hydrogum 5 (H5), Hydrogum (H), Orthoprint (O), and Jeltrate Plus (JP). The different alginate powders (0.5 mg) were fixed on plastic stubs (n = 5...

In late 2014, a H5N8 highly pathogenic avian influenza (HPAI) virus, clade 2.3.4.4, spread by migratory waterfowl into North America reassorting with low pathogenicity AI viruses to produce a H5N2 HPAI virus. Since domestic waterfowl are common backyard poultry frequently in contact with wild waterfowl, the infectivity, transmissibility, and pathogenicity of the United States H5 HPAI index viru...

Several new highly pathogenic (HP) H5 avian influenza virus (AIV) have been detected in poultry farms from south-western France since November 2015, among which an HP H5N1. The zoonotic potential and origin of these AIVs immediately became matters of concern. One virus of each subtype H5N1 (150169a), H5N2 (150233) and H5N9 (150236) was characterised. All proved highly pathogenic for poultry as ...

Procedures are described for the dissociation of histones H1 and H5 from chicken reticulocyte chromatin without disruption of the native core histone-DNA complex. The comparative properties of native and depleted chromatin with respect to sedimentation, thermal denaturation, and sensitivity to nuclease digestion have been studied. The changes in these properties resulting from removal of the li...
