‘Causal’ blood pressure genes found in the human kidney

An international team of scientists led by The University of Manchester have discovered 179 kidney genes responsible for high blood pressure. High blood pressure, known as “silent killer”, is one of the most common human diseases and remains the key risk factor for strokes and heart attacks. High blood pressure […]

Repairing Nerves Requires Prods of Protein

It turns out the 'bad guys' of the brain aren't so bad after all. When there’s damage in the body, our cells call for help. UConn brain researchers just found a new way cells do this—like in the old AT&T ad campaign, they reach out and touch someone. Or some […]

Study: what brain scans reveal about learning math

When you’re solving a challenging math problem, you know your brain is working hard. But what, exactly, is going on in there? Despite decades of research into math teaching and learning, there is still much to learn about how specific brain functions are tied to math skills. A new University […]

Epilepsy research reveals why sleep increases risk of sudden death

New research from the University of Virginia School of Medicine reveals why sleep can put people with epilepsy at increased risk of sudden death. Both sleep and seizures work together to slow the heart rate, the researchers found. Seizures also disrupt the body’s natural regulation of sleep-related changes. Together, in […]

Exploring the possibilities of hyaluronic acid

Hyaluronic acid (HA) is more than a buzzword ingredient touted by skincare brands. The “workhorse” capabilities of this biopolymer, which is present in most mammalian tissues, have fascinated scientists for decades. A new cover story in Chemical & Engineering News, the weekly newsmagazine of the American Chemical Society, details HA’s complex […]

New marker predicts benefit of radiotherapy for early-stage breast cancer

A study involving researchers at Karolinska Institutet and Gothenburg University has found that low levels of a protein called PDGFRb are associated with particularly good results of radiotherapy in women with early-stage breast cancer. The study, which is published in the journal Clinical Cancer Research, also suggests that the efficacy […]

Large study links dementia to poor kidney function

Older people with kidney disease have a higher risk of dementia, and the risk increases with the rate and stage of kidney function decline. That is according to a large observational study by researchers at Karolinska Institutet in Sweden, published in the journal Neurology. The findings stress the significance of […]

New map reveals genes that control the skeleton

Researchers have mapped the gene activity of osteocytes to improve their understanding of skeletal disease. Research led by the Garvan Institute of Medical Research has for the first time mapped the unique genetic profile of the skeleton’s ‘master regulator’ cells, known as osteocytes. The study published in Nature Communications outlines the […]

Researchers develop better way to determine safe drug doses for children

Determining safe yet effective drug dosages for children is an ongoing challenge for pharmaceutical companies and medical doctors alike. A new drug is usually first tested on adults, and results from these trials are used to select doses for pediatric trials. The underlying assumption is typical that children are like […]

Biologists discover a trigger for cell extrusion

For all animals, eliminating some cells is a necessary part of embryonic development. Living cells are also naturally sloughed off in mature tissues; for example, the lining of the intestine turns over every few days. One way that organisms get rid of unneeded cells is through a process called extrusion, […]

Researchers find obesity linked to reduced blood flow to the brain

A new study from scientists at The Irish Longitudinal Study on Ageing (TILDA) at Trinity College Dublin reveals important findings, indicating that being overweight or obese significantly reduces blood flow in the brain. The study also shows that increased physical activity can positively modify, or even negate, this reduction in […]

Gene Therapy in Alzheimer’s Disease Mouse Model Preserves Learning and Memory

Researchers at University of California San Diego School of Medicine, with colleagues elsewhere, have used gene therapy to prevent learning and memory loss in a mouse model of Alzheimer’s disease (AD), a key step toward eventually testing the approach in humans with the neurodegenerative disease. The findings were published online […]

Cerebral hemorrhage linked to stroke, cardiac risks

People who have experienced a cerebral hemorrhage or brain bleed have a two-fold increase in the risk of having an ischemic stroke (caused by an artery blockage) or heart attack, compared with members of the general population, according to new research from investigators at Weill Cornell Medicine and NewYork-Presbyterian. The […]

Structural Approach to Cancer

This year, more than 60,000 adults in the United States will be diagnosed with pancreatic cancer and, statistically, as few as 10 percent will survive five years after diagnosis, according to the American Cancer Society. Because pancreatic cancer is hidden deep within the body and often symptomless, it’s frequently diagnosed […]
