Study Preserves Memory in mice, offering promising new basis for Active Immunization against Alzheimer’s disease

During experiments in animal models, researchers at the University of Kansas have discovered a possible new approach to immunization against Alzheimer’s disease (AD).

Their method uses a recombinant methionine (Met)-rich protein derived from corn that was then oxidized in vitro to produce the antigen: methionine sulfoxide (MetO)-rich protein. This antigen, when injected to the body, goads the immune system into producing antibodies against the MetO component of beta-amyloid, a protein that is toxic to brain cells and seen as a hallmark of Alzheimer’s disease. The findings have been just published in the peer-reviewed open-access journal Antioxidants.

“As we age, we have more oxidative stress, and then beta-amyloid and other proteins accumulate and become oxidized and aggregated ...

‘Resetting’ the Injured Brain Offers Clues for Concussion Treatment

About 85% of traumatic brain injuries are similar to the type of concussion examined in this study, involving dispersed impact to the head.

In mice, ‘turning over’ cells reverses cognitive, behavior problems. New research in mice raises the prospects for development of post-concussion therapies that could ward off cognitive decline and depression, two common conditions among people who have experienced a moderate traumatic brain injury.

The study in mice clarified the role of specific immune cells in the brain that contribute to chronic inflammation. Using a technique called forced cell turnover, researchers eliminated these cells in the injured brains of mice for a week and then let them repopulate for two weeks.

“It’s almost like hitting the reset butt...

AI-enabled ECGs may Identify Patients at Greater risk of Stroke, Cognitive Decline

Atrial fibrillation, the most common cardiac rhythm abnormality, has been linked to one-third of ischemic strokes, the most common type of stroke. But atrial fibrillation is underdiagnosed, partly because many patients are asymptomatic.

Artificial intelligence-enabled electrocardiography (ECG) was recently shown to identify the presence of brief episodes of atrial fibrillation, and the ability of an AI-enabled ECG algorithm to predict atrial fibrillation up to 10 years before clinical diagnosis has been confirmed in a population-based study conducted by Mayo Clinic researchers.

A new population-based study from Mayo Clinic now offers evidence that the algorithm can help identify patients at greater risk of cognitive decline...

The new technology could make at-home diagnosis of diseases faster and more affordable. A University of Minnesota Twin Cities research team has developed a new microfluidic chip for diagnosing diseases that uses a minimal number of components and can be powered wirelessly by a smartphone. The innovation opens the door for faster and more affordable at-home medical testing.

The researchers’ paper is published in Nature Communications, a peer-reviewed, open access, scientific journal published by Nature Research...
