Before launching their latest science experiment, University at Buffalo researchers bought more than 200 types of tea, chocolate, herbs and other foodstuffs. The goal wasn’t to stock up for long hours in the lab, but rather to find an elusive, edible contrast agent to show doctors what’s happening inside our bodies. The search culminated with a winner: barley. Turns out […]

(HealthDay)—If you’re fit in middle age, you might be guarding against not only depression as a senior, but also dying from heart disease if you do develop depression, a new study suggests. Among nearly 18,000 Medicare patients, the most fit were 16 percent less likely to develop depression, the researchers found. The most fit were also 56 percent less likely […]

A new device under development by a nuclear engineering professor will allow doctors to dispense accurate dosages of a drug made with actinium-225, an isotope that has been shown to be effective in treating—and curing—myeloid leukemia. The device, devised by Assistant Professor Eric Lukosi and fabricated by master’s student William Gerding, is currently in production. Once it is built, it […]

The advent and advancement of T cell therapy, especially chimeric antigen receptor (CAR)-modified T cells, has demonstrated therapeutic potential in treating previously treatment-resistant tumors. However, few CAR targets are absolutely tumor-specific, resulting in “on-target, off-tumor” toxicities that can be severe. Researchers in the Center for Cell and Gene Therapy at Baylor College of Medicine, Texas Children’s Hospital and Houston Methodist […]

It is well known that chronic sleep deprivation can affect cardiovascular health. But according to a new study from Columbia University Irving Medical Center, even mild sleep problems, such as having trouble falling asleep, can raise blood pressure in women. Nearly one-third of adults don’t get enough sleep. For women, the problem may be even bigger. Studies suggest that women […]

A potentially new way of treating cerebral malaria has been discovered by scientists at the Universities of Manchester and Glasgow, in a study using mice. The authors found that inhibiting a complex called the inflammasome, at the same time as delivering anti-malarial drugs, reduced mortality from experimental cerebral malaria in mice. The research, published in PNAS and funded by the […]

“This is a virus transmitted by mosquitoes that circulates between birds. It can attack the nervous system of certain birds, such as blackbirds, and cause significant mortality. It was first observed in southern Africa, in Swaziland, in 1959,” says Serafin Gutierrez, a virology researcher with CIRAD”S ASTRE research unit. The virus, called Usutu, belongs to the genus Flavivirus, which includes […]

,Updated blood pressure guidelines from the American Heart Association mean that many more Americans, notably older people, are now diagnosed with high blood pressure, or hypertension. This may sound like bad news, but the new guidelines highlight some important lessons we cardiologists and heart health researchers have learned from the latest blood pressure studies. Specifically, we have learned that damage […]

Researchers from Queen’s University Belfast have shown for the first time that the eye could be a surrogate for brain degeneration like Alzheimer’s disease (AD). This research results have recently been published in the Journal of Ophthalmic Research and is the first clinical study showing a potential for peripheral retinal imaging to be used in monitoring AD and potentially other […]

The squeeze high blood pressure puts on fragile blood vessels in the brain appears to disrupt a normal, protective process that balances the blood flowing to our brains with the activity of our resting neurons. In the face of hypertension, as blood flow decreases, neuron-nurturing brain cells called astrocytes may instead tell neurons to increase their activity, says Dr. Jessica […]
