Development and Validation of the Foot Union Scoring Evaluation Tool for Arthrodesis of Foot Structures.

Reliable evaluation of osseous consolidation after pedal arthrodesis can be difficult, and the presence or absence of radiographic healing often dictates care. Plain radiographs remain the mainstay imaging tool owing to their cost, efficiency, and low radiation exposure. Applying radiographic parameters that can reliably determine osseous healing is essential.

Radiographic Union Scoring Scale for Determining Consolidation Rates in the Calcaneus.

The reliable evaluation of osseous consolidation after hindfoot osteotomy can be difficult. Concomitant hindfoot osteotomies often dictate the advancement of weightbearing, and radiographs are the mainstay imaging tool owing to cost, efficiency, and radiation exposure. Understanding the radiographic parameters that can be used to reliably determine osseous healing is paramount.

Antiviral activity of gliotoxin, gentian violet and brilliant green against Nipah and Hendra virus in vitro.

Background: Using a recently described monolayer assay amenable to high throughput screening format for the identification of potential Nipah virus and Hendra virus antivirals, we have partially screened a low molecular weight compound library (>8,000 compounds) directly against live virus infection and identified twenty eight promising lead molecules. Initial single blind screens were conducted with 10 microM compound in triplicate with a minimum efficacy of 90% required for lead selection. Lead compounds were then further characterised to determine the median efficacy (IC50), cytotoxicity (CC50) and the in vitro therapeutic index in live virus and pseudotype assay formats.

Simulating henipavirus multicycle replication in a screening assay leads to identification of a promising candidate for therapy.

Nipah (NiV) and Hendra (HeV) viruses are emerging zoonotic paramyxoviruses that cause encephalitis in humans, with fatality rates of up to 75%. We designed a new high-throughput screening (HTS) assay for inhibitors of infection based on envelope glycoprotein pseudotypes. The assay simulates multicycle replication and thus identifies inhibitors that target several stages of the viral life cycle, but it still can be carried out under biosafety level 2 (BSL-2) conditions.
