Supporting Zika virus drug screening in Brazil

Several outbreaks of the Zika virus have been reported around the world since its discovery in 1947, but a commercially available treatment for the disease is still not available, and scientists continue to search for the best antiviral agent. Professor Martin Würtele and his colleagues in the Department of Science and Technology at the Federal University of São Paulo recently published a study identifying several natural substances that showed potent antiviral activity against the Zika virus protease.

Revolutionizing long DNA synthesis by speeding up the process

Synthetic DNA has become the central component of countless scientific and technological innovations across many applications, from biopharmaceuticals to biofuels. However, research and drug development pipelines are often hindered by the cost and the length of time that it takes to obtain long sequences of DNA or multiple DNA variants. Ribbon Biolabs, based in Vienna, is addressing this issue by combining automation and adaptive algorithmic control with highly precise, optimized enzymatic synthesis.

Salivary stress biomarkers to nose out the benefits of healthcare clowning to children with psychiatric disorders

Several studies have shown that healthcare clowning has a strong positive effect on pediatric patients in general, but there is limited research into its impact on those with psychological disorders. RED NOSES Clowndoctors Austria – an organization with decades of experience in healthcare clowning – is addressing this issue through a collaboration with the Department of Clinical and Health Psychology at the University of Vienna. A joint study is currently being conducted in several psychiatric in-patient wards across Austria, using salivary stress biomarkers to assess whether clown visits are really benefitting patients.

A voyage of discovery: exploring the role of HMGB1 in trauma pathology

Trauma is the main cause of premature death internationally, resulting in more deaths in people under 40 years old than all other causes combined. Even trauma victims receiving hospital care have a high mortality rate, in part due to massive systemic inflammatory reactions leading to the dysfunction of organs that were not initially injured. A team at Oslo University Hospital in Norway has been investigating the role of the protein HMGB1 (High Mobility Group Box 1) in the development of trauma pathologies and its potential as a clinical biomarker or therapeutic target in these cases.

Fighting the opioid epidemic by reducing manual labor and increasing throughput

Opioid addiction, alongside addiction to other substances, is a significant public health, social and economic challenge in the US. In 2017, the opioid epidemic was declared a public health emergency by the Department of Health and Human Services, with one of its aims to improve access to treatment and recovery services. Despite this, over 100,000 US lives were lost to opioid overdoses in the year to April 2021. Increasingly, outpatient centers such as Ideal Option are providing medication-assisted treatment (MAT) – combining approved medications with counseling and support therapy – to offer a ‘whole-patient’ approach to treatment of, and sustained recovery from, these addictions.

Quality food and feed enzyme development at the industrial scale

The use of enzymes as biocatalysts in industrial applications has steadily gained popularity, as it offers an efficient way to use raw materials while minimizing waste. This approach has been successfully scaled for commercial processes in the pharmaceutical, food and beverage industries, largely thanks to the use of automation to screen, optimize and produce suitable enzymes. Roal Oy in Rajamäki, Finland – a leading producer of industrial enzymes – has automated large parts of its enzyme discovery and screening activities to accelerate product development and optimization.

Trust your gut – advances in microbiome DNA analysis

The human gut microbiome has been found to affect metabolic health and nutrient absorption, and preliminary research also suggests that it contributes to the development of the immune response, food allergies and intolerances, obesity, and a wide range of other conditions. This field is the focus of Ortho-Analytic, an integrative medicine laboratory based in Wallisellen, Switzerland, that identifies bacterial, fungal and parasite DNA found in stool samples. The company uses molecular genetic analyses to build a detailed picture of a patient’s gut microbiome, aiding practitioners in formulating specific treatment plans.

Generating a cellular infection model for monitoring SARS-CoV-2 replication

Work to characterize and further understand the molecular pathology of SARSCoV- 2 became a focus for many virology departments following the identification of the novel virus responsible for COVID-19. Drs Marek Widera, Alexander Wilhelm and colleagues at University Hospital Frankfurt, Germany, turned their attention to developing an in vitro cell culture model that could realistically mimic the viral replication cycle, to decipher the mechanism of COVID-19 infection.

Automating a herd of tests

The COVID-19 pandemic is an important reminder that pathogens are not only transmitted via air and contact with other humans, but also from animals and through food. This highlights the need for effective diagnostic tools that offer fast testing of animal and environmental samples to help monitor livestock and aquaculture. Qualyse is a French company that does exactly this, using advanced laboratory automation to provide immunoserology and molecular diagnostic testing for up to 12,000 samples a day.

Exploring zoonotic pathogens in Australian livestock

Antimicrobial resistance is a growing issue preventing the effective treatment of numerous parasitic diseases in both humans and animals. The lack of effective antimicrobials for the treatment of a growing number of diseases represents a serious threat to global public health, making it imperative that governments and societies around the world take action to tackle this issue. Scientists at the University of Murdoch in Australia are studying antimicrobial resistance in livestock – which can potentially spread to humans – using a statistical approach of surveillance to monitor the situation more closely.

Mitosis as a potential therapeutic target for cancer? A divided topic

Mitosis plays an essential role in growth and cellular replacement, and is often dysregulated in cancers, making the process of therapeutic interest. Researchers at the University of North Carolina at Chapel Hill (UNC Chapel Hill) are developing novel cell imaging tools to help them classify key components of mitosis and identify new therapeutic targets.
