The prevalence of Alcohol Use Disorders represents a serious concern given the deleterious impacts observed on individuals, their families, and society more widely. A better understanding of the factors associated with the development and recovery of Alcohol Use Disorders is essential to the development of more effective treatments. This is the focus of research by Dr Sara Blaine from Auburn University, USA.
Being overweight is a well-recognised risk factor for the development of chronic diseases such as diabetes, heart diseases, and certain types of cancer. As such, obesity represents a significant public health issue worldwide. It is the leading cause of death in the USA, notably in Arkansas, where Dr Jamie I. Baum, at the Department of Food Science at the University of Arkansas, is exploring, with her colleagues, the relationship between dietary protein intake and its impact on body composition and metabolism to develop efficient nutritional guidelines to prevent and treat obesity.
Ultraviolet radiation (UVR) from sunlight has been identified as a leading risk factor for the development of melanoma. Despite numerous research studies, the molecular mechanisms underlying the link between UVR and melanoma remain still poorly understood. Dr Chengyu Liang, from The Wistar Institute in Philadelphia and her collaborators from the University of Southern California have identified the function of the UV irradiation resistance associated gene (UVRAG). Their studies show that inactivation of UVRAG affects the ability of the cell to repair UVR-induced damage mechanisms. The researchers also provide compelling in vivo validation of a novel prognostic and predictive biomarker in melanoma.
Fracking has long been controversial for its potential to contaminate local water sources and cause damage to the environment. Dr Kathleen Mullen at Littleton Equine Medical Center in Colorado and her team have carried out novel research into how fracking in close proximity to a horse-breeding farm may be the cause of a specific birth defect in the foals born there. Her findings may be relevant to human babies and considerations of the implications of fracking on long-term health.
Dr J. Kenneth Hoober | Dr Laura L. Eggink – Glycomimetic Peptides as Immune System Activators in the Treatment of Cancer and Viral Infections
Immune system cells express a number of receptors that bind to sugar ligands. This binding initiates the activation of T-cell lymphocytes and natural killer cells. Dr J. Kenneth Hoober, Dr Laura L. Eggink and the team at Susavion have designed peptides that bind to different receptors on immune cells. The peptides effectively extend the lives of mice with glioblastoma and ovarian cancer, and prevent the replication of viruses in the presence of non-neutralising antibodies. The mechanism of action of their peptides could inspire the development of effective treatments for Covid-19 and other viral infections.
Severe traumatic brain injury (TBI) is associated with high rates of disability and even mortality. Understanding the relationship between patient outcomes and the treatment received, as well as other physiological factors such as inflammation, can improve how we approach TBI. Dr Jack Jallo and his team from the Department of Neurological Surgery at Thomas Jefferson University are researching the factors that influence TBI recovery to help design better care management protocols and optimise patient recovery.
Meningitis and septicaemia are serious, life-threatening illnesses that can kill within hours. The Meningitis Research Foundation (MRF) is the leading UK, Irish and international charity working to bring together people and expertise to defeat these diseases. In this exclusive interview, we speak with Vinny Smith, Chief Executive, to hear about their vital work, key achievements and future plans.
Malnutrition, occurring as either a lack of food or not eating enough of the right types of food, is a significant concern in many African countries, particularly for children. To address this issue, Dr Marlyse Leng and her colleagues at the University of Douala in Cameroon have recently developed a nutritious weaning food for infants, made from an endangered yam species to increase its production and use. After processing the yam with other key nutrients into an optimised formulation, they explored the food’s nutrient availability and antioxidant activity in comparison to other products.
Dr Claudine Bruck | Professor Edward Morrisey | Professor Jason Burdick – A Hydrogel with the Ability to Recover Heart Function
The human heart is a muscle, and like all types of muscles, it can be injured. In humans, heart muscle is not able to regenerate after injury, and this can lead to heart disease which develops over time, eventually leading to an untimely death. A team of researchers, Doctor Claudine Bruck (Prolifagen), Professor Edward Morrisey (Department of Medicine and Cell and Developmental Biology) and Professor Jason Burdick (Department of Bioengineering) at the University of Pennsylvania, have collaborated to develop a novel therapy to regenerate damaged heart muscle.
Dr Charles Vite – Naturally Occurring Diseases in Dogs and Cats Help to Develop Treatments for Inherited Neurological Disorders
Many inherited neurological diseases are rare but can have severe outcomes, frequently resulting in disability and even death for children. New treatment options are essential to prevent suffering and decrease mortality, but to find such treatments, these diseases need to be more closely studied. Dr Charles Vite and his team at the School of Veterinary Medicine, University of Pennsylvania, are committed to achieving these goals. By utilising animal models and unique markers for inherited neurological disease, they have already delivered promising results supporting the development of new treatment options.
Prolonged exposure to nitrate from contaminated water affects the transport of oxygen in blood. Nitrate can react with haemoglobin, oxidising it into methaemoglobin, which is unable to carry oxygen. High methaemoglobin levels among infants result in a medical condition known as methaemoglobinemia or blue baby syndrome. Dr Mina Sadeq and her team from the National Institute of Hygiene in Morocco, conducted two studies to investigate the combined effects of nitrate and bacteria on the development of methaemoglobinaemia in infants and young children.
Epilepsy is one of the most common causes of disability worldwide, but for many patients, treatment fails to be effective. Dr Victoria Morgan and her team from the Department of Radiology and Radiological Sciences at Vanderbilt University Medical Center are using functional connectivity mapping to find out why some patients respond better to treatment and what alternative ways there may be to tackle this debilitating disorder.
Dr Anton Iliuk – A Non-invasive, Low-cost Procedure to Detect Cancer Biomarkers from Biological Fluids
Liquid biopsies have recently gained attention as sources of non-invasive diagnostic cancer biomarkers. Traditional biofluid sampling methods, however, are onerous and time-consuming and present many limitations including poor sensitivity for biomarkers in low concentrations. Dr Anton Iliuk and his team at Tymora Analytical Operations, West Lafayette, USA, have developed a way to isolate extracellular vesicles from plasma, urine and other biofluids. They now aim to grow their network of collaborators to use their platform for the discovery of protein biomarkers from several cancers, neurodegenerative diseases, and other conditions.
Medical conditions that affect the brain can have severe impacts on people’s lives. Many of these conditions can be difficult to treat, including epilepsy which affects the brain to cause seizures and the common form of dementia known as Alzheimer’s disease. Dr Arun Swaminathan at the University of Nebraska Medical Center specialises in the treatment of epilepsy. He also collaborates with fellow researchers to explore treatment options for Alzheimer’s disease.
Applying mathematics to biology can help reveal the elusive details of life. Professor Wilfred D. Stein and his colleagues from the Hebrew University of Jerusalem and institutes worldwide have used quantitative tools to tackle topics ranging from cancer treatment to drug-resistant malaria, and lately, the evolution of the human genome. His extensive and broad work has supported scientists in many different areas of biomedicine and will leave a lasting impact on life science.
In recent years, scientific and technological advances have brought great innovation within the life sciences industry, introducing the need for entrepreneurship training for medical and engineering graduates. With this in mind, Michal Gilon-Yanai, Dr Robert Schneider and their collaborators developed an academic program designed to provide students and faculty members with the skills they need to become successful entrepreneurs. The team of collaborators includes Dr Gabrielle Gold-von Simson, an expert in implementing academic programs, and Dr Colleen Gillespie, who specialises in education, evaluation and dissemination science. Their pioneering program trains students on how to bring new biomedical technologies to the market.
Dr Richard B. Brandon | Dr Thomas D. Yager – A Fully Integrated Diagnostic Test to Discriminate Sepsis from Infection-negative Systemic Inflammation
Sepsis is a serious medical condition that manifests with a dysregulated immune response to an infection in the bloodstream, and is a major cause of morbidity and mortality worldwide. Many non-infectious conditions can lead to a state of hyper-inflammation known as the systemic inflammatory response syndrome (SIRS), which clinically can look very similar to sepsis. A lack of analytical tools that allow for the early detection of sepsis makes discrimination between sepsis and SIRS a very complex but critical diagnostic task. Dr Richard B. Brandon, Dr Thomas D. Yager and their colleagues at Immunexpress have developed a molecular diagnostic platform capable of detecting genetic biomarkers diagnostic for sepsis in about an hour. Early sepsis diagnosis can potentially lead to better patient management, more efficient use of resources, and a more sensible approach to the use of antibiotics.
Healthcare systems around the world are under increasing pressure as a result of depleting resources accompanied by rising demands. Dr Johannes Bircher’s reflections on the inherent failings of modern healthcare systems have coalesced into an important proposal for a new concept of health, known as the Meikirch model. Here, we look at the potential of the Meikirch model to drive forward a critical paradigm shift in healthcare delivery.
Dr Yasuhiro Sakai | Dr Kazuhiko Kuwahara – GANP: An Immunoactive Protein with a Key Role in Tumourigenesis
Investigating the role of an immune system protein, GANP, and its coding gene, ganp, Dr Yasuhiro Sakai and Dr Kazuhiko Kuwahara (Fujita Health University School of Medicine) have unveiled a potential role for this important protein in tumourigenesis. The scientists apply a multidisciplinary approach to identify potential therapeutic solutions to aid cancer prognosis, a collaboration that occurs in the emerging field of immunopathology. The researchers focus on the differential levels of GANP which appear to correlate with breast cancers (low GANP) and with lymphocytic cancers (high GANP).
The rise of pandemic-causing viruses is a worrying development arising as a by-product of our hugely connected world, and scientists must forge new paths to tackle these diseases. With researchers like Dr Babita Agrawal from the University of Alberta at the helm, we can hope to enter a new era of preventatives and therapeutics to help us fight disease. Dr Agrawal and her team are investigating novel vaccines and immunotherapeutics for influenza, Hepatitis C, tuberculosis, and even cancer.
Ubiquitin is a polypeptide that is tagged on to various proteins to signal a range of biological processes. The alteration of the ubiquitin system plays a pivotal role in the pathogenesis of diseases including autoimmune disorders and cancer. The process of ubiquitinylation involves a cascade of enzymes, E1, the activating enzyme, E2 (conjugating enzymes) and E3 (ligases). Characterisation of the ubiquitinylation process of key proteins that impact stems cells, immune cells, and cancers is vital to identify therapeutic targets which may influence the progression of autoimmune conditions and cancers. The ubiquitin system is compromised in the majority of cancers and is the focus of research by Dr Yi Sheng of York University, Canada.
Dr Logan M. Lawrence – Evidence-Informed Decision Making: Breaking Down the Walls Between Researchers and Policy Makers
Anyone who has worked closely with government, be it local, national or international, will know the frustrations of trying to influence policy and decision makers. The ‘dark arts’ of the political analyst and the political lobbyist, particularly those that seem to succeed in having influence, remain a mystery to many. Dr Logan M. Lawrence at Dalhousie University, Nova Scotia, explores the concept of ‘policy capacity’ to try and understand, measure and operationalise the best approaches to assist and support policy makers to make ‘the right decisions’.
Brain tumours and other central nervous system diseases can be exceptionally difficult to treat. This is often due to the blood-brain barrier which can pose a significant obstacle when trying to get drugs to their intended site of action. Dr Sean Lawler and his team from Brigham and Women’s Hospital, Harvard Medical School are aiming to bridge the gap between laboratory research and clinical treatment in their quest to find new ways to effectively deliver therapies to the brain and treat challenging diseases, especially the lethal brain tumour glioblastoma.
Multidrug resistance is one of the main culprits underlying the failure of chemotherapy as a cancer treatment. Whilst many therapies are initially effective, a considerable proportion of patients eventually incur a poor prognosis and recurrence of malignant spread due to developing drug resistance at a later stage. Dr Rock J. Mancini, from Washington State University, has devised an approach that exploits proteins over-expressed in drug-resistant cancers to convert inactive prodrug substrates into active drugs that initiate an immune response targeted at cancer cells.
Since the turn of the century, a myriad of exciting applications for graphene have emerged. Amongst the most exciting might be its use as a scaffold for promoting tissue growth in the treatment of various medical conditions, including osteoarthritis. Researchers at Boise State University in the USA and Carl von Ossietzky University of Oldenburg in Germany are gaining a greater understanding of the interactions between graphene and cells, towards the development of implantable graphene-based devices that can rebuild damaged tissue.

The effectiveness of cancer treatments could be hugely improved by a greater understanding of the cancer genome. This is the focus of the work of Dr John Paul Y.C. Shen, MD, of the University of Texas MD Anderson Cancer Center, who is creating comprehensive molecular ‘maps’ of cancer cells and their interactions. Understanding cancer at a molecular level is the first step towards Dr Shen’s very real hope of bringing personalised cancer treatments into the clinic.
Professor Dr André Fringer | Mrs Sabrina Stängle – The Voluntary Stopping of Eating and Drinking: Dying with Dignity?
To die with dignity is a common wish but not one that is easily granted. Professor Dr André Fringer and Mrs Sabrina Stängle, both of the Zurich University of Applied Sciences, are investigating the voluntary stopping of eating and drinking (VSED) as a means to hasten death as an alternative to active euthanasia. Their work is driving forward our understanding of the medical and ethical ramifications of this practice.
The discovery of DNA has been one of the most important findings of the last century, yet there is still much more to uncover about the ‘additional chemical layer’ brought about by the chemical modification of amino acids and nucleotide bases. A large collaboration of researchers at institutions across Germany, known as SFB 1309, is led by Professor Thomas Carell at the Ludwig-Maximilians University in Munich. A key focus of SFB 1309 is to elucidate the details of the second layer of information beyond the sequence layer of biochemical molecules called Watson-Crick bases within our DNA.
Head and neck squamous cell carcinoma (HNSCC) constitutes around 90% of all head and neck cancers. Millions of individuals are diagnosed across the globe every year, very often too late and with poor prognosis. Among other factors, alcohol consumption and smoking increase the risk to develop HNSCC. Dr Muy-Teck Teh, from Queen Mary University of London, is driving forward our understanding of the factors leading to cancer, leading the development of novel less invasive detection methods, and progressing better therapeutic options.
Scientists and clinicians rely on data to inform their practice and make decisions in a variety of medical settings. For data to be meaningful they need to be translated into actionable information and interpreted by the user. Access to a sheer amount of data can, in itself, pose a challenge. Dr Guo-Qiang ‘GQ’ Zhang from the University of Texas Health Science Center at Houston (UTHealth) has developed several innovative systems that provide a user-friendly interface for handling large-scale, multi-centre clinical data.
