Professor Stephan Pleschka | Professor M Lienhard Schmitz – The Influenza A Genotype and Cell Signalling Networks
Influenza viruses pose a major threat despite advances in vaccine and drug development. Research into the cellular and molecular mechanisms that drive influenza viruses aims to reveal new drug targets to fight disease. However, information on the molecular mechanisms of how influenza viruses infect and replicate in host cells is currently limited. As part of the German Collaborative Research Centre 1021 (CRC1021), Professors Stephan Pleschka and M Lienhard Schmitz at the Justus Liebig University Giessen in Germany are exploring the impact of the genetic variability of influenza viruses on the interactions between the virus and host cell that regulate viral infection and replication.
Steve Green – Development of New Anti-Rollback Device Provides Pain Relief for Wheelchair Users
It is estimated that in the USA alone, over 2.7 million individuals require a wheelchair for mobility. By far the greatest fraction of manual wheelchair users rely on conventional manual pushrim drive wheelchairs, yet the use of such wheelchairs leads to well-documented shoulder injuries and chronic pain. We read here of how Steve Green of Green Technologies, Inc, is tackling this problem through the development and patenting of a wheelchair anti-rollback device that addresses these injury and safety issues with an innovative yet simple mechanism.
Dr Yan M Yufik – From Machine Learning to Machine Understanding

Dr Yan M Yufik, Head at Virtual Structures Research Inc, USA, is a physicist and cognitive scientist who has spent over 20 years combining experimental findings and theoretical concepts in domains as diverse as neuroscience and thermodynamics to form a theory of the brain. His focus has been on elucidating the mechanisms underlying human understanding and applying the results to the design of machines that can not only learn but understand what they are learning.
Dr Akihiro Ito – Improving the Diagnosis of Legionnaires’ Disease
Legionella bacteria are known to cause Legionnaire’s disease, a potentially severe and lethal form of pneumonia. The bacteria can be classified into different serogroups forming specific sub-types of L. pneumophila. In humans, serogroup 1 is the most common cause of pneumonia, being responsible for approximately 80% of all cases. However, the other subgroups can also cause pneumonia, resulting in a range of outcomes from mild to severe, and these are more difficult to accurately detect. Dr Akihiro Ito at Kurashiki Central Hospital, Japan, is advancing the detection of all forms of L. pneumophila to facilitate more timely healthcare interventions for Legionnaires’ disease.
Dr Jarrad Scarlett – Targeting the Brain in Type 2 Diabetes: Therapeutics to Induce Remission
Type 2 diabetes (T2D) is among the most impactful and costly biomedical challenges confronting society. Current treatment regimens for T2D rely upon daily drug dosing and frequent glucose monitoring to normalise blood glucose levels. However, these medications can only delay disease progression and frequently have undesired side effects including hypoglycaemia and weight gain. Growing evidence supports a key role for the brain in glucose homeostasis and diabetes pathogenesis. Dr Jarrad Scarlett and his research team at the University of Washington and Seattle Children’s Hospital are working on the development of novel pharmaceuticals to target the brain to induce sustained remission of T2D.
Dr Amy Schmidt – iAMResponsibleTM: Educating Food Producers & Consumers About Antimicrobial Resistance
Antimicrobial resistance (AMR), the acquired ability of microorganisms to withstand the effects of medications used to treat them, is a serious and growing threat to public health. In collaboration with experts from various US institutions, Dr Amy Schmidt at the University of Nebraska-Lincoln has developed a program called the iAMResponsibleTM Project, aimed at educating consumers, agricultural producers and others on the risks associated with AMR, as well as strategies to mitigate these risks.
Dr Fay B Horak – Wearable Technology to Detect Risk of Falling and Frailty
Accidental falls are one of the leading causes of injuries and accidental death for the elderly, and the risk of falling increases significantly in those with neurological disorders or frailty. Dr Fay B Horak and her colleagues at Oregon Health & Science University and APDM Wearable Technologies, USA, are investigating the use of APDM’s novel wearable technology to monitor mobility in daily life of individuals at risk of falling to help prevent falls and identify prefrail elderly individuals.
Dr Bettina Pause – More than Just Words: The Chemical Communication of Social Information
As humans, we communicate our emotions to others in several different ways, including touch, motion, facial expression, and of course, speech. We can also communicate social information through chemosensory signals. Dr Bettina Pause, a professor at Heinrich-Heine-Universität Düsseldorf, has carried out extensive research exploring human communication and sensory perception, and in particular, how we quickly and effectively convey emotional states such as anxiety and aggression to others without even using words.
Dr Tammy Movsas, MD, MPH – Towards a Brighter Future: How Zietchick Research Institute Plans to Transform Treatment for Retinal Disease
Both diabetic adults and premature babies are at risk for a similar type of eye disease that involves the growth of abnormal, blood vessels in the retina, the photosensitive layer of the eye. When this eye disease occurs in diabetics, it is called diabetic retinopathy and when it occurs in premature infants, it is called retinopathy of prematurity. The pathologic vessels, seen in both of these diseases, can pull on the retina and cause it to detach, leading to blindness. Dr Tammy Movsas (Executive Director and Principal Investigator) and Dr Arivalagan Muthusamy (Chief Scientist) at the Zietchick Research Institute, USA, are developing new therapeutics to treat these serious retinal diseases that affect both premature baby eyes and mature adult eyes, such as those of diabetic women.

Dr Frank Wuest – Innovative Strategies for Imaging Cancers
Global Navigation Satellite Systems such as GPS are the backbone of many global communications, but they are not immune to failure. Progeny Systems Corporation is dedicated to mitigating such disasters if and when satellite-based communications fail, by developing Earth-based systems that work in comparable ways to synchronised satellite networks. As an alternative to GPS, the company’s technology could provide communicating parties with a crucial yet inexpensive safeguard against future failures.
Simphotek: Shedding Light on New Cancer Treatments
The use of radiation therapy to treat cancer has improved the long-term outcome of thousands of patients but is associated with serious side effects. Photodynamic therapy (PDT), a targeted light-based technique, has been approved as an effective treatment for some forms of cancer with fewer side effects than radiotherapy. However, the effectiveness of this technique depends on fine-tuning its application to the patient. Simphotek, a US-based company founded by world leaders in biophysics and computer modelling, together with its collaborative partners at Roswell Park Comprehensive Cancer Center and the Hospital of the University of Pennsylvania, is focused on expanding novel technologies of PDT as a cancer treatment for solid tumours.
Dr York Hsiang – Going with the Flow: New methods for Treating Cardiovascular Disease
When an artery becomes blocked or damaged, a mechanical scaffold called a stent is often implanted into the vessel to improve blood flow. However, metallic stents can cause re-narrowing at the sites where they are implanted. This process is known as restenosis, which can lead to lethal complications. Dr York Hsiang, Professor of Surgery at the University of British Columbia, and his team use microengineering techniques to develop novel stents that can better detect restenosis, and treat it earlier when it occurs.
Dr Susan Voglmaier – Driving Forward Training and Research in Psychiatry
In recent years, dramatic advances have been made in brain science and molecular genetics. However, there is currently a shortage of psychiatrists with the scientific training necessary to take this knowledge and apply it in the clinic. Psychiatrist and neuroscience researcher, Dr Susan Voglmaier of the University of California, San Francisco, runs a research training program that supports the next generation of research scientists in the field of psychiatry. Dr Voglmaier believes that by training doctors in scientific techniques and methods, we may come to better understand mental illness and provide more effective treatments for psychiatric diseases in the future.

Professor Douglas Goff – Soluble Dietary Fibre and Type 2 Diabetes – Mechanisms of Action and Food Supplementation
There are numerous health benefits related to eating fibre-containing foods, including lowering the levels of serum glucose and lipids, thus reducing the risk of type 2 diabetes and heart disease. Furthermore, by creating an increased feeling of fullness, eating fibre-rich foods reduces caloric intake and obesity. Professor Douglas Goff from the University of Guelph, Ontario, Canada, researches the supplementation of food with fibre and the specific mechanisms of beneficial action, with a focus on blood glucose reductions after eating a carbohydrate-rich meal. Along with his team, his goal is to define the relationship between the molecular structure and physiological functionality of soluble dietary fibres.

Given the high prevalence and extent of impairment inflicted on affected individuals, the economic cost to public health is substantial. Professor Christine Larson at the University of Wisconsin-Milwaukee, USA, seeks to identify new and more effective targets for intervention by better understanding the relationship between brain function, cognitive processing, and emotion.
Dr Elena Galkina – Immune Control of Initiation and Progression of Atherosclerosis
Atherosclerosis is a global health issue. Atherosclerosis is a multifactorial chronic inflammatory disease characterised by the accumulation of modified lipoproteins and immune cells in the aortic wall, vascular dysfunction, low-grade chronic inflammation, and formation of dangerous atherosclerotic plaques within the medium and large size vessels. Atherosclerosis is a prominent cause of cardiovascular diseases and mortality in many countries and this disease is closely associated with type 2 diabetes. Dr Elena Galkina, Professor of Microbiology and Molecular Cell Biology at Eastern Virginia Medical School, USA, has been working to determine the immune processes involved in an attempt to identify much-needed novel therapies.
Professor Etienne Sibille | Professor James Cook – Lifting Brain Fog
Effective treatments for cognitive dysfunction, such as declines in memory and other mental faculties often associated with depression or old age, may be within reach, according to Professor Etienne Sibille at the Centre for Addiction and Mental Health (CAMH) and the University of Toronto, Canada. Professor Sibille has shown for the first time that newly synthesised compounds targeting GABA receptors improve specific types of memory in mice, opening the door to the development of effective new pharmacological options.
Dr Elizabeth Nance – The Role of Nanoparticles in Neuroscience
Dr Elizabeth Nance has an impressive track record. Now a Clare Boothe Luce Assistant Professor of Chemical Engineering at the University of Washington, USA, Dr Nance’s work centres around the use of nanoparticles to deliver therapeutic agents to the brain, a seemingly simple operation which is confounded by a highly regulated blood brain barrier which prevents access to the brain and a complex brain environment which prevents access to diseased cells. Her current work also investigates the potential use of nanoparticles to probe tissue environments to map tissue structure, and how tissue structure changes in the presence of a disease.

Professor Jeansok Kim – Understanding Fear in Animals
Research into animal fear typically utilises laboratory techniques based on Pavlovian fear conditioning, but these approaches are limited. Professor Jeansok Kim, from the Department of Psychology, University of Washington (USA) has developed a much more realistic way to study fear that closely mimics risky conditions in the wild. New discoveries by Professor Kim and his team are challenging existing paradigms and providing exciting insights into the underlying brain mechanisms of fear in both animals and humans.
Professor Mark D’Esposito – Everyday Miracles: Unravelling the Mysteries of Working Memory
To accomplish even a simple goal, our brain must coordinate thousands of pieces of information, remember which parts are relevant, and ignore anything that is extraneous. Dr Mark D’Esposito of the University of California, Berkeley, studies how different parts of the brain work together to create working memory, the cognitive system that temporarily and actively holds information in mind allowing us to complete complex tasks.
Professor Mark D’Esposito – Leveraging New Technologies to Treat Brain Injury
The brain is the most mysterious organ in the human body – despite decades of research, we have just begun to scratch the surface in understanding how the brain works and how we can help it to heal following an injury. Professor Mark D’Esposito of the University of California, Berkeley, uses advanced imaging technology to illuminate how the connections in our brain function in order to find new ways to aid brain healing after injury.
Dr Baowei Fei – A New Technique for Targeted Prostate Cancer Biopsies
Two-dimensional transrectal ultrasound (TRUS) guided biopsy is the standard method for prostate cancer diagnosis. However, the technique is limited in one respect – it can be prone to sampling error. Cancers can be missed, or their severity grossly underestimated. To address this, Dr Baowei Fei, from the University of Texas (UT) at Dallas and UT Southwestern Medical Center, is pioneering a technique that merges positron emission tomography (PET) with TRUS to detect prostate cancer more accurately than before.
