Using PET-CT scans to track the elimination of radiolabeled plastic particles in mice

Postdoctoral Researcher Outi Keinänen from the University of Helsinki developed a method to radiolabel plastic particles in order to observe their biodistribution on the basis of radioactivity with the help of positron emission tomography (PET).

PET radiotracer can noninvasively identify and monitor pulmonary fibrosis

Positron emission tomography (PET) using a 68Ga-labeled fibroblast activation protein inhibitor (FAPI) can noninvasively identify and monitor pulmonary fibrosis, according to research presented at the Society of Nuclear Medicine and Molecular Imaging 2021 Annual Meeting.

FDA grants accelerated approval for first-of-its-kind Alzheimer's treatment

Today, the U.S. Food and Drug Administration approved Aduhelm (aducanumab) for the treatment of Alzheimer's, a debilitating disease affecting 6.2 million Americans. Aduhelm was approved using the accelerated approval pathway, which can be used for a drug for a serious or life-threatening illness that provides a meaningful therapeutic advantage over existing treatments.

University of Freiburg professor honored for groundbreaking results on the brain’s immune system

The blood-brain barrier is an impenetrable barrier between the circulating blood and the brain established before birth that prevents immune cells from entering the brain from the body's immune system. Thus, the brain has its own immune system with a key actor called microglia.

Moderate alcohol intake may be heart protective by reducing stress-related brain signals

Moderate alcohol intake--defined as no more than one alcoholic drink for women and two for men per day--has been associated with a lower risk of dying from cardiovascular disease when compared with individuals who abstain from drinking or partake in excessive drinking, according to a new study being presented at the American College of Cardiology's 70th Annual Scientific Session.

PET imaging can enable accurate diagnosis of recurring brain metastases

For patients with brain metastases, amino acid positron emission tomography (PET) can provide valuable information about the effectiveness of state-of-the-art treatments.

$3.5 million grant awarded to address the underrepresentation of Black adults in Alzheimer's research

Black adults are more likely than other groups to develop Alzheimer's disease or related disorders but are poorly represented in Alzheimer's disease research, including recent clinical trials. This health disparity illustrates how Black individuals can benefit from advances in the field if they had access.

Researchers provide a promising new way to elucidate the brain's health

Researchers from the Center for BrainHealth at The University of Texas at Dallas are investigating a potential new early indicator of the decline toward Alzheimer's disease: measuring the energy metabolism of the living human brain using cutting-edge imaging techniques.

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.

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.
