Intense trauma can have long lasting effects on the brain and behavior of healthy people without causing a clinical disorder

Exposure to trauma may create enough changes in the brain to sensitize people to overreact to an innocuous facial gesture years later, even in people who don't have a stress-related disorder, says new research.

CT angiography has a nearly 100% detection rate in acute ruptured, cerebral aneurysms

CTA correctly detected the ruptured aneurysm in 170 cases when compared to intraoperative findings, Bijal Patel, MD, lead author of the study. Of the 22 cases where there was more than one aneurysm, CTA correctly identified the ones that were ruptured every time.

CT colonoscopy has 90 percent agreement rate with optical colonoscopy

Nearly 90% of colon polyps greater than or equal to 6 mm in size detected at CT colonoscopy were demonstrated to represent true polyps at subsequent optical colonoscopy (the traditional method of viewing the colon and removing precancerous growths), according to a new study by researchers from the University of Wisconsin Hospital and Clinics in Madison, WI.

Brain cells 'talk' with each other in more ways than previously thought

Johns Hopkins scientists have discovered to their surprise that nerves in the mammalian brain's white matter do more than just ferry information between different brain regions, but in fact process information the way gray matter cells do.

Loss of a single gene in kidney cancer cells causes them to stop making mitochondria

Studying a rare inherited syndrome, researchers at Johns Hopkins have found that cancer cells can reprogram themselves to turn down their own energy-making machinery and use less oxygen, and that these changes might help cancer cells survive and spread.

Simple blood test for BNP levels predictive of higher in-hospital mortality rates for heart failure patients

A simple blood test, beyond standard lab tests, taken at hospital admission strongly predicted in-hospital mortality risk for heart failure patients and may be useful in helping doctors decide which patients need higher-level monitoring and more intensive treatment.
