Accelerating Therapeutic Development for Brain Illnesses

IRP Study Finds Brain Imaging Technique Could Aid Clinical Trials

We all crave instant gratification, but unfortunately, most things worth doing take time. This certainly applies to evaluating treatments for many illnesses, as observable changes in patients’ symptoms can take weeks or months to appear. Fortunately, new NIH research has revealed that a particular way of non-invasively peering into the brain could help accelerate the development of treatments for a variety of rare neurological diseases.

Recapturing Kids’ Bone-Healing Magic

IRP Study Suggests Immune System Changes Hinder Healing in Adults

With all the hijinks that young children and teenagers get up to, it’s a good thing they heal so quickly from a broken leg or arm. Unfortunately, this ability begins to diminish within a few years of graduating high school. Now, new IRP research is showing that changes in the immune system underlie the difficulties older individuals have with repairing their bones.

AI-Powered ‘Digital Twins’ Predict Liver Donors’ Futures

IRP Study Shows Potential of Machine Learning Algorithms in Personalized Medicine

Despite the potential drawbacks of time travel demonstrated in countless sci-fi movies, most people wouldn’t mind some advice from their future self. What they might not think about is how useful their doppelganger’s knowledge of the future could be to their doctor. IRP researchers hope an AI-powered computer model they’ve developed could provide those kinds of predictive medical insights for people recovering after donating a portion of their liver to someone in need of a transplant.

A Promising New Tool to Combat Antibiotic-Resistant Bacteria

IRP Research Demonstrates the Perks of Overlooked Immune System Molecules

Countless Hollywood romances rely on the trope that, every so often, it turns out the thing you’ve been searching for has been right in front of you all along. Thanks to new IRP research, a molecule long-studied for its role in directing immune cells’ movement around the body is being seen in a new light as a potentially important player in medicine’s life-or-death struggle against antibiotic-resistant infections.

A Brain Signal Biomarker for Cerebral Palsy Treatments

Study Points to Potential Way to Improve Physical Therapy Interventions for Movement Disorder

It’s easy to take everyday activities like walking and typing for granted, but for people with cerebral palsy, any movement can be a struggle. Intensive physical therapy, starting at a young age, has long helped those individuals move more easily. Now, recent IRP research could provide a way to track how those and other treatments affect communication within the brain during movement, providing a tool that could help researchers more quickly evaluate which treatments work and which don’t.

Alcohol Accelerates Cardiovascular Aging

IRP Research Suggests Older Adults May Benefit From Severely Limiting Alcohol Consumption

It seems like every news report touting the health benefits of a daily glass of wine is soon followed by another that claims consuming any amount of alcohol harms health. While the jury is still out on this issue for younger individuals, a recent IRP study suggests that alcohol consumption may accelerate the typical age-related erosion of the cardiovascular system.

Many scientific studies have established the myriad ways that aging and alcohol independently diminish the capacity of the heart and blood vessels to effectively move blood — and the vital oxygen and nutrients it carries — around the body. However, the effects of those two forces in combination remains an outstanding question with potentially significant implications for health and public policy.

A Crystal Ball for Prostate Cancer Treatment

IRP’s Dr. Adam Sowalsky Looks to Tumors’ Origins to Predict Outcomes

Imagine two men, both diagnosed with prostate cancer. For one, the disease will remain a quiet shadow, never seriously threatening his life. For the other, it will become an aggressive adversary, resisting treatments and altering his future. This June, as Men's Health Month brings such realities into focus, a critical question echoes in clinics and labs: how can we identify early on which cancer will turn dangerous, and how can we use that knowledge to change a patient's outcome for the better? 

IRP senior investigator Adam G. Sowalsky, Ph.D., believes the answer lies not just in how cancer adapts during treatment, but in the evolutionary traits it already possesses when it first emerges. 

Calming Kids’ Runaway Emotions

Brain Research Helps Understand and Treat Childhood Anxiety

It’s perfectly normal for young children to throw tantrums or be nervous on their first day of school, and for adolescents to be anxious about what their peers think of them. However, for some children and teens, negative emotions can escalate to unhealthy levels, resulting in significant distress and impairing their quality of life. 

IRP senior investigator Daniel Pine, M.D., is on a mission to understand how that happens and figure out ways to help those kids. In honor of Mental Health Month, we talked with Dr. Pine about how his research is revolutionizing the field of pediatric psychiatry and paving the way for new, non-pharmaceutical treatments.

Dieting May Disrupt Women’s Sleep

IRP Study Reveals Influence of Calorie Intake and Reproductive Cycle on Sleep

Doctors have long emphasized the importance of maintaining a healthy body weight and getting enough sleep, but in our time-limited lives, we often have to choose between spending time exercising, preparing healthy meals, and getting sufficient shuteye. And the number of hours in the day may not be the only thing that pits weight loss against sleep. A recent IRP study suggests that young women who are not obese get poorer sleep when they change their diets in order to lose weight.

Startling Snapshots of Science

Vibrant Images Push Forward Environmental Health Research

Scientists and artists obviously don’t spend their days doing the same thing, but that doesn’t mean the former can’t sometimes inadvertently be the latter. Take for example the 14 IRP research fellows who submitted images to the most recent edition of the Fellows Scientific Image Competition at NIH’s National Institute of Environmental Health Sciences (NIEHS). The competition, held every few years, shows that biomedical science can not only save lives, but also look good doing it.

“We are excited to showcase the work of our trainees using visual media, which reminds us there is art in science and showcases the important research we’re all engaged in at NIEHS,” says NIEHS Scientific Director Darryl Zeldin, M.D., who initiated the competition.
