The Virtual Child.

We are building the world's first Virtual Child-a computer model of normal and cancerous human development at the level of each individual cell. The Virtual Child will "develop cancer" that we will subject to unlimited virtual clinical trials that pinpoint, predict, and prioritize potential new treatments, bringing forward the day when no child dies of cancer, giving each one the opportunity to lead a full and healthy life.

A method for the systematic selection of enzyme panel candidates by solving the maximum diversity problem.

Enzymes are being increasingly exploited for their potential as industrial biocatalysts. Establishing a portfolio of useful biocatalysts from large and diverse protein family is challenging and a systematic method for candidate selection promises to aid in this task. Moreover, accurate enzyme functional annotation can only be confidently guaranteed through experimental characterisation in the laboratory.

Development of inactivated heartwater (Ehrlichia ruminantium) vaccine in South Africa.

Heartwater, Ehrlichia ruminantium infection in cattle, sheep, goats, and some wild ruminants, is an economically important disease in Africa characterized by high mortality rates in susceptible populations. In South Africa, the current commercial heartwater vaccine is an infection and treatment type of immunization using virulent live E. ruminantium organisms generated from blood of infected sheep with subsequent treatment of the animals with antibiotics at specific times during the course of infection.

SARS-COV-2 spike binding to ACE2 in living cells monitored by TR-FRET.

Targeting the interaction between the SARS-CoV-2 spike protein and human ACE2, its primary cell membrane receptor, is a promising therapeutic strategy to prevent viral entry. Recent in vitro studies revealed that the receptor binding domain (RBD) of the spike protein plays a prominent role in ACE2 binding, yet a simple and quantitative assay for monitoring this interaction in a cellular environment is lacking. Here, we developed an RBD-ACE2 binding assay that is based on time-resolved FRET, which reliably monitors the interaction in a physiologically relevant and cellular context.

The challenge of generalist care in remote Australia: Beyond aeromedical retrieval.

Objective: To examine clinical service activity amongst patients of the Royal Flying Doctor Service South Eastern Section in Far West New South Wales and to evaluate the management of chronic disease among frequent users of evacuation services.

Design: A retrospective audit of the Royal Flying Doctor Service South Eastern Section patient database inclusive of patients within the geographical study area who accessed a clinical or remote consultation, or evacuation service at least once between 1 July 2008 and 30 June 2013. Frequent users of evacuation services (≥3 evacuations per year) were investigated through RFDS patient files for determinants of chronic disease management.
