Dr Jennifer Kay | Professor Bevin Page Engelward – The MIT Superfund Research Program: Studies on Cleaning Up Genes and the Environment

In the United States, there are thousands of industrial sites contaminated by the irresponsible disposal of chemical waste. The higher than expected frequency of cancer cases near these sites has caused alarm, since many of the chemical contaminants found at these sites have been linked to the development of long-term health problems, including cancer. As leaders of the Massachusetts Institute of Technology Superfund Research Program, Dr Jennifer Kay (Research Scientist and Research Translation Director) and Professor Bevin Page Engelward (Program Director) are using their expertise to investigate the genetic factors that influence susceptibility to adverse health outcomes following exposure to environmental chemicals.

Professor Steven E. Wilson – Clearing the Haze: Understanding the Process of Scarring Following Corneal Injury

Any injury such as trauma, surgery or infection to the cornea in the eye may result in persistent scarring (clinically referred to as fibrosis) due to the wound healing response. Professor Steven E. Wilson at the Cole Eye Institute of the Cleveland Clinic Foundation has identified that defective epithelial basement membrane (EBM) regeneration plays a central role in the development of scar producing myofibroblast cells. Critically, Professor Wilson suggests that the pathophysiological consequences of defective EBM regeneration are also likely to have wider relevance to the fibrosis that occurs in other organs, such as the lungs, heart, kidneys, and skin.

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.

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.

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.
