New biomarkers help predict response to treatment in common brain tumor

Many scientists have noted that there is a link between inflammation or the immune response, and patient survival. One such possible relationship is the association of blood markers and the prognosis in the brain tumor called medulloblastoma.

Virginia Tech scientist receives American Heart Association award to study stroke recovery

When someone has an ischemic stroke, doctors work swiftly to remove the arterial blockage and restore blood flow to the brain. But sometimes even once the blockage is removed, there's lasting - sometimes fatal - damage.

Brain changes may help track people most likely to develop dementia

Even before dementia diagnosis, people with mild cognitive impairment may have different changes in the brain depending on what type of dementia they have, according to a study published in the September 11, 2019, online issue of Neurology, the medical journal of the American Academy of Neurology.

Cell adhesion protein promotes metastasis in breast cancer, study reveals

Researchers at the Johns Hopkins Kimmel Cancer Center discovered that a cell adhesion protein, E-cadherin, allows breast cancer cells to survive as they travel through the body and form new tumors, a process termed metastasis.

Supercooling helps preserve human transplant organs longer

Now a new supercooling technique for human organs promises to extend the period from the moment of removal to 1.5 days rather than just a few hours. This provides a useful window of time within which transplant teams and patients can hope to get a viable organ.

Treating high blood pressure may slow cognitive decline

High blood pressure appears to accelerate cognitive decline among middle-aged and older adults, but treating high blood pressure may slow this down, according to a preliminary study presented by researchers at Columbia University Mailman School of Public at the American Heart Association's Hypertension 2019 Scientific Sessions.

Mobile apps improve atrial fibrillation detection rates in a low-risk population

A new study has shown that mobile health (mHealth) devices are able to screen for the common cardiac disorder called atrial fibrillation (AF).

Researchers find synergistic connection between two deadly blood-clotting diseases

Two rare but potentially deadly blood-clotting diseases, namely thrombotic thrombocytopenic purpura, or TTP, and hemolytic uremic syndrome, or HUS, show similar pathologies -- a multitude of painful blockages in small blood vessels that cause varying degrees of organ injury throughout the body. However, the two disorders have distinct biological mechanisms.

Machine learning may augment diagnostics of kidney disease

Two new studies reveal that modern machine learning--a branch of artificial intelligence in which systems learn from data, identify patterns, and make decisions--may augment traditional diagnostics of kidney disease. The findings appear in an upcoming issue of JASN.

Mouthwash impacts the effects of exercise

Scientists have long known that the blood pressure drops after exercise but the mechanism has not been fully elucidated. A new study shows that bacteria in the mouth, which produce nitrite, is key to the whole process. The use of mouthwash to reduce the number of these bacteria prevents the expected benefit of exercise on the blood pressure.

Lab-grown brain organoids and the brains of preemie babies generate similar electrical impulses

Brain organoids — also called mini-brains — are 3D cellular models that represent aspects of the human brain in the laboratory. Brain organoids help researchers track human development, unravel the molecular events that lead to disease and test new treatments.

Inflammation in the lungs triggers silent mutation to cause pulmonary hypertension

Researchers at the Stanford University School of Medicine have found that inflammation in the lungs of rats, triggered by something as simple as the flu, may wake up a silent genetic defect that causes sudden onset cases of pulmonary hypertension, a deadly form of high blood pressure in the lungs.
