UVA's imaging approach could help identify brain surgery targets to stop epilepsy seizures

An advanced imaging approach developed at the University of Virginia School of Medicine could let surgeons determine the best target in the brain to stop epilepsy seizures, new research suggests.

Researchers assess the theoretical impact of biomarker framework on dementia prediction

One of the biggest challenges in Alzheimer's research is to identify biomarkers that can identify people who are at risk of developing dementia. Biomarkers could be used to screen people so they might be helped before they develop dementia.

Researchers develop computer model to predict the impact of individual receptors on brain activity

Researchers regard the overall distribution of receptors in the brain – the receptome – as a new approach for computer models that reproduce the function of the brain, and for diagnostics and therapy of mental disorders.

Novel PET tracer is safe and can clearly identify early stages of rheumatoid arthritis

New research shows that a novel positron emission tomography (PET) tracer that targets inflammation is safe and can clearly identify early stages of rheumatoid arthritis.

Researchers discover a novel marker of adult human neural stem cells

The mammalian center for learning and memory, hippocampus, has a remarkable capacity to generate new neurons throughout life. Newborn neurons are produced by neural stem cells (NSCs) and they are crucial for forming neural circuits required for learning and memory, and mood control.

New technique traces genetic and epigenetic origins of DNA to reveal hidden cancers

A new technique that can trace which tissues and organs the DNA in our blood comes from has been reported today in the open-access eLife journal.

Immuno-PET detects changes in different cancer receptors in response to targeted therapies

Immuno-positron emission tomography (PET) imaging can provide early insight into a tumor's response to targeted therapy, allowing physicians to select the most effective treatment for patients who have cancer.

Newly developed maps show how human brains are kept nourished

Our brains are non-stop consumers. A labyrinth of blood vessels, stacked end-to-end comparable in length to the distance from San Diego to Berkeley, ensures a continuous flow of oxygen and sugar to keep our brains functioning at peak levels.

Researchers study how seasons influence the brain function

A Finnish research group has studied how seasons influence the function of the brain. Researchers at the Turku PET Centre showed that the length of daylight affects the opioid receptors, which in turn regulates the mood we experience.

Periodontal inflammation associated with higher risk of major cardiovascular events

People with periodontitis are at higher risk of experiencing major cardiovascular events, according to new research from Forsyth Institute and Harvard University scientists and colleagues.

Novel method for rapid and efficient separation of oxygen-18 from oxygen-16

Positron Emission Tomography (PET) plays a major role in the early detection of various types of cancer.

Molecular imaging can predict response to novel metastatic breast cancer treatment

Molecular imaging can successfully predict response to a novel treatment for ER-positive, HER2-negative metastatic breast cancer patients who are resistant to hormonal therapy.

New model predicts which patients will gain most from PSMA PET scan

A new study led by researchers at the UCLA Jonsson Comprehensive Cancer Center helps identify which patients with prostate cancer will benefit most from the use of prostate-specific membrane antigen PET imaging, PSMA PET, a novel imaging technique that recently was approved by the U.S. Food and Drug Administration.

Controlling cardiovascular disease risk factors early in life may protect against later dementia

Employing cardiovascular disease prevention strategies in mid-life may delay or stop the brain alterations that can lead to dementia later in life, according to a study in the Journal of the American College of Cardiology.

Study finds link between brain metabolism, cardiovascular risk, and atherosclerosis

The links between cardiovascular disease and cognitive impairment begin years before the appearance of the first clinical symptoms of either condition.

Star-shaped brain cells may play a key role in stuttering

Astrocytes -- star-shaped cells in the brain that are actively involved in brain function -- may play an important role in stuttering, a study led by a University of California, Riverside, expert on stuttering has found.

Metal-containing radiopharmaceuticals could improve access to diagnostic imaging of AD

A team of researchers from the Laboratory of Biophysics at NUST MISIS, Lomonosov Moscow State University and D. Mendeleev University of Chemical Technology of Russia has summarized metal-containing diagnostic agents for positron emission tomography (PET), magnetic resonance imaging (MRI), and single-photon emission computed tomography (SPECT) imaging of Alzheimer's disease (AD).

New study reviews effect of coffee on people's sleep and wake cycles

The Institute for Scientific Information on Coffee (ISIC) published a new report today, titled 'Coffee and sleep in everyday lives', authored by Professor Renata Riha, from the Department of Sleep Medicine at the University of Edinburgh.

Automated method identifies and tracks harmful tau deposits involved in Alzheimer's disease

Amyloid-beta and tau are the two key abnormal protein deposits that accumulate in the brain during the development of Alzheimer's disease, and detecting their buildup at an early stage may allow clinicians to intervene before the condition has a chance to take hold.

Study shows link between early brainstem tau accumulation and cortical hyperexcitability

Study conducted by researchers from the GIGA CRC In vivo Imaging laboratory at ULiège demonstrates, for the first time in humans, how the first deposits of tau proteins in the brainstem are associated with neurophysiological processes specific to the early stages of Alzheimer's disease development.
