Changes in estrogen can trigger atypical functioning in memory circuit of women with gene variant

Fluctuations in estrogen can trigger atypical functioning in a key brain memory circuit in women with a common version of a gene, NIMH scientists have discovered.

Brown fat in humans: more than previously thought

Brown fat is a tissue well studied in small mammals, where it acts as a heat-producing organ to stay warm in a cold environment. Its unequivocal identification in adult, healthy humans about a decade ago is of major importance due to its immense capacity to convert chemical energy into heat

Northwestern Memorial first in Illinois to integrate combined MR-PET scanner into health care system

Northwestern Memorial Hospital is now home to the Chicago area's first combined magnetic resonance and positron emission tomography scanner, a machine that shortens the total time a patient spends in imaging tests while providing exceptional image quality at lower doses of radiation.

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.

New gene linked to Tau pathology

Investigators at Rush University Medical Center and the Brigham and Women's Hospital in Boston reported the discovery of a new gene that is associated with susceptibility to a common form of brain pathology called Tau that accumulates in several different conditions, including Alzheimer's disease, certain forms of dementia and Parkinsonian syndromes as well as chronic traumatic encephalopathy that occurs with repeated head injuries.

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.

Brown fat in humans three times greater than previously known, TUM study shows

Compared to white fat, brown body fat burns through energy at an extraordinary rate. However, until now the proportion of brown fat in humans was thought to be quite small.

New research reveals brain chemistry involved in human bonding

In new research published Monday in the journal Proceedings of the National Academy of Sciences, Northeastern University psychology professor Lisa Feldman Barrett found, for the first time, that the neurotransmitter dopamine is involved in human bonding, bringing the brain's reward system into our understanding of how we form human attachments.

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.

New molecular imaging technologies can make it easier to treat cancers, minimize side effects

New molecular imaging technologies can make it easier to diagnose, monitor, and treat cancers while potentially saving patients from undergoing therapies that are likely to be ineffective and playing a role in minimizing side effects, according to experts from the Abramson Cancer Center and the Perelman School of Medicine at the University of Pennsylvania.

Study reveals impact of histology on SBRT treatment in early-stage NSCLC patients

Early-stage non-small cell lung cancer (NSCLC) patients with squamous cell carcinoma (SqCC) have a significantly higher rate of local failure after stereotactic body radiation therapy (SBRT) than other NSCLC histological subtypes.
