Stimulating the Brain with Magnetic Fields Can Control Movement

Scientists have developed a method to stimulate small clusters of brain cells using magnetic fields. Using this technique, they were able to control movement in mice. Understanding how the brain works is an ongoing effort, with a huge number of research teams working intensively to unlock its secrets. As part of this effort, an international [&hell (Read more...)

Older patients at higher risk for class 2 uveal melanoma tumors

BOSTON — Class 2 uveal melanoma tumors are associated with older age, tumor size, ciliary body involvement and exudative retinal detachment, according to a poster presented at the American Society of Retina Specialists meeting.Duncan Berry, MD, and colleagues presented the multi-institutional study, which consisted of 379 patients with posterior uveal melanoma treated with I-125 plaque brachytherapy. Patients had concurrent tumor biopsies submitted for gene expression profile, which classified 263 patients as having class 1 tumors and 113 as having class 2 tumors.

New Material to Help Repair Brain Tissue Damaged by Stroke

One of the reasons why strokes are so devastating is that brain tissue does not exhibit the same healing mechanisms as other tissues that repair themselves quickly. Integrin proteins are responsible for some of the healing processes, including getting new cells to move and having them adhere to the extracellular matrix, and these are not stron (Read more...)

Miniature Bioengineered Vessels to Study Progeria Therapies

Progeria is a rare but deadly disorder that is commonly known as an early aging disease, bringing forth conditions in children that are normally only reserved for older adults. To better study how to fight progeria, a disease that significantly affects the cardiovascular system, researchers at Duke University have developed a way to grow tiny [&hel (Read more...)

New Optical Tool to Spot Nerves During Surgery

A team of medical researchers has come up with a way to optically spot nerves within tissue, which should prevent nerve injuries that can happen during surgeries of the hand and other sensitive and delicate parts of the body. The technology uses something called collimated polarized light imaging (CPLi) and by rotating the polarization, one is (Read more...)
