Nanoparticles help untangle Alzheimer's disease amyloid beta plaques

ROCKVILLE, MD - Scientists are still a long way from being able to treat Alzheimer s Disease, in part because the protein aggregates that can become brain plaques, a hallmark of the disease, are hard to study. The plaques are caused by the amyloid beta protein, which gets misshapen and tangled in the brain. To study these protein aggregates in tissue samples, researchers often have to use techniques that can further disrupt them, making it difficult to figure out what s going on. But new research by Vrinda Sant, a graduate student, and Madhura Som, a recent PhD graduate, in the lab of Ratnesh Lal at the University of California, San Diego, provides a new technique for studying amyloid be ....

Deep learning amyotrophic lateral sclerosis by taking pictures


Kyoto University
A team of scientists led by CiRA Professor Haruhisa Inoue reports the combination of deep learning and iPS cell technology for the diagnosis of amyotrophic lateral sclerosis (ALS).
For many devasting neurological diseases like Alzheimer’s disease and amyotrophic lateral sclerosis (ALS), patients are diagnosed only after becoming symptomatic. However, the evidence of memory and muscle loss is seen only after the disease has progressed to irreversible states. Researchers are therefore exploring ways to identify patients well before they become symptomatic, which could allow for wider clinical options.
“If we can catch the disease at the reversible stage, we may reverse and cancel the disease.” said CiRA Prof. Haruhisa Inoue, a specialist of ALS research using iPS cells. ....

Repetitive compression of limbs appears to aid recovery from deadly brain bleeds

AUGUSTA, Ga. (Feb. 25, 2021) - Scientists want to know more about how an inexpensive, low-risk treatment may improve recovery from the most deadly type of stroke.
The treatment, remote ischemic conditioning, or RIC, involves successive bouts of compressing then relaxing an arm or leg with a blood pressure-like cuff, most typically for four cycles of five minutes of inflation followed by five minutes of deflation.
The most deadly stroke is an intracerebral hemorrhage, the most common form of hemorrhagic stroke, in which blood, which is toxic to brain tissue, spills out of blood vessels in the brain. ....
