Cold-induced fat-like molecules help fuel metabolism in mice

Activated by cold, the small amounts of brown fat scattered around your body can burn calories to warm you up. They also can help to lower insulin resistance and other conditions implicated in type 2 diabetes and obesity.

Optical imaging tool could help track the brain's circulatory response to acute pain in adults, infants

Functional near-infrared spectroscopy (fNIRS), an optical imaging tool for monitoring of regional blood flow and tissue oxygenation, is being explored as a way to track the brain's response to acute pain in adults and infants.

Novel statistical approach reveals details about brains' internal networks in patients with epilepsy

A novel statistical approach to analyzing patients with epilepsy has revealed details about their brains' internal networks. The findings may lead to better understanding and treatment of the disease, according to Rice University researchers.

New PET radiotracer can quickly, non-invasively detect life-threatening atherosclerotic plaques

In the featured article of the March 2017 issue of "The Journal of Nuclear Medicine," researchers demonstrate that a new positron emission tomography radiotracer, gallium-68 (Ga-68)-pentixafor, can quickly and non-invasively identify life-threatening atherosclerotic plaques.

Direct radiolabeling of nanographene materials enhances bioimaging accuracy, reduces biases

Positron emission tomography plays a pivotal role for monitoring the distribution and accumulation of radiolabeled nanomaterials in living subjects. The radioactive metals are usually connected to the nanomaterial through an anchor, a so-called chelator, but this chemical binding can be omitted if nanographene is used, as American scientists report in the journal Angewandte Chemie

Glucose deprivation in the brain triggers onset of cognitive decline, research shows

One of the earliest signs of Alzheimer's disease is a decline in glucose levels in the brain. It appears in the early stages of mild cognitive impairment -- before symptoms of memory problems begin to surface.

Study reveals how migration increases person's risk of developing schizophrenia

A new study could explain how migrating to another country increases a person's risk of developing schizophrenia, by altering brain chemistry.

High-fat, low-sugar diet prior to imaging can help reduce uncertainty in diagnosing cardiac sarcoidosis

Researchers at the University of Illinois at Chicago were able to reduce uncertainty in diagnosing cardiac sarcoidosis by having patients consume a high-fat, low-sugar diet for 72 hours prior to diagnostic imaging.

Landmark clinical trial to test third investigational drug for Alzheimer's disease

An international team led by Washington University School of Medicine in St. Louis has selected a third investigational drug to be tested in a worldwide clinical trial - already underway - aimed at finding treatments to prevent Alzheimer's disease.

Novel approach combines imaging and electroanatomical mapping for targeted cardiac gene transfer

Gene therapy to repair damaged heart muscle is most likely to succeed if it can be injected at the site of ischemia where there is viable myocardium with reduced contractile ability, and a new technique that combines imaging and electroanatomical mapping does just that.
