Got pain? Get better sleep
The cell phone blares out reveille. Your eyes open reluctantly and you realize it’s morning, having only gone to bed four hours earlier because of a late-night party. You creak out of bed to ready yourself for work, arthritic joints hurting much more than usual. A painful day lies ahead even after taking ibuprofen. Does this sound familiar? If it does, you are not alone. Nearly 70% of Americans report getting insufficient sleep on a regular basis, and approximately 20% of Americans suffer from chronic pain. Recently, the intersection between these two conditions has become more apparent.
The association between sleep def...

Widely Used Neuroimaging Analyses Allow Almost Any Result To Be Presented As A Successful Replication, Paper Claims
Of 135 surveyed fMRI papers that contained claims of replicating previous findings, over 40 per cent did not consider peak activity levels within brain regions – a flawed approach that allows almost any result to be claimed as a successful replication (from YongWooK Hong et al, 2019)
By Matthew Warren
As the list of failed replications continues to build, psychology’s reproducibility crisis is becoming harder to ignore. Now, in a new paper that seems likely to ruffle a few feathers, researchers suggest that even many apparent successful replications in neuroimaging research could be standing on shaky ground. As the ...

Kansas State University Welcomes New MRI for Large Animals
A new magnetic resonance imaging (MRI) machine at Kansas State University, which took three years to install, is finally ready to scan neurological injuries in large animals.According to KSNT, this is the Midwest ’s first MRI of its kind. Its fast imaging speed reduces the amount of time animals have to spend in the machine. According to David Biller, professor of radiology at Kansas State’s College of Veterinary Medicine, the MRI offers several advantages that conventional scanners lack. “We will be a ble to image smaller structures more rapidly,” he said. “With the greater detail or ability to image smaller s...

Participants In This Study Successfully Down-regulated Their Amygdala Activity With The Help Of Neurofeedback
This study supports existing research showing promise for the application of rt-fMRI neurofeedback in the treatment of problems like PTSD, addiction and depression that are associated with heightened amygdala activation. The clinical potential of this technique, bridging the worlds of neurobiology and psychotherapy, is clear. That said, fMRI scanning is an expensive business, so it may be a while before a new world of personalised mental health interventions reveals itself.

MRI is a Non-Invasive Way to Detect Hypoxia in Breast Cancer Patients
Hypoxia and neovascularization in breast cancer can now be identified using magnetic resonance imaging (MRI) techniques, according to a studyrecently published inMolecular Imaging and Biology.Researchers from the Medical University of Vienna were intrigued by a couple of recently developed imaging methods that successfully analyzed hypoxia in patients with brain cancer and wanted to see if the same technology could be used to detect the condition in breast cancer patients. Advanced quantitative blood oxygenation level dependent (qBOLD) imaging can evaluate tissue oxygen and measure tumor hypoxia. Vascular architectural m...

RSNA and ACR Introduce RadInfo 4 Kids
In an effort to help kids understand the daunting mechanismsof imaging machines, RadiologyInfo.org, a patient resource site sponsored and created by the Radiological Society of North America (RSNA) and the American College of Radiology (ACR) has launched RadInfo 4 Kids, an interactive site that helps children learn about medical scans.RadInfo 4 Kids has a collectionof games, videos, stories, and activities that help kids get emotionally and mentally prepared for their scan procedure. It can be challenging for children to grasp what happens in the scanner, so to get on their level, the site directors have also provided ...

Fight Aging! Newsletter, January 28th 2019
In this study, we show that calorie restriction is protective against age-related increases in senescence and microglia activation and pro-inflammatory cytokine expression in an animal model of aging. Further, these protective effects mitigated age-related decline in neuroblast and neuronal production, and enhanced olfactory memory performance, a behavioral index of neurogenesis in the SVZ. Our results support the concept that calorie restriction might be an effective anti-aging intervention in the context of healthy brain aging.
Greater Modest Activity in Late Life Correlates with Lower Incidence of Dementia

Towards Reliable, Low-Cost Tests for the Earliest Stages of Alzheimer's Disease
The research community has moved quite determinedly these past few years towards practical, low-cost tests for early Alzheimer's disease. Even with the limited means available to patients today, an early warning might be used to delay the aggregation of amyloid-β that takes place in the initial stages of the condition, before the appearance of cognitive impairment. Lifestyle changes such as weight loss and improved fitness, antiviral therapies, and control of chronic inflammation should all make some difference, given what is known of the mechanisms of Alzheimer's disease. Looking ahead, better options may soon be availab...

Could Gas-Based Contrast Agents Replace GBCAs?
Researchers from the Leibniz Institute for Molecular Pharmacology (FMP) in Berlin and the California Institute of Technology are creatinghyperpolarized xenon gas-based contrast agents that will improve the sensitivity of magnetic resonance imaging (MRI), according to a studypublished inACS Nano.The gas-based contrast agents, or “gas vesicles”, aim to solve the problems presented by traditional gadolinium-based contrast agents (GBCAs). GBCAs lack sensitivity and often demand high quantities, which can pose health risks. They ’re generated by specific bacteria, and behave similarly to a fish’s swim bladder, which ...

BrainCarta Maps Creates Maps for Brain Surgeries: CES 2019
Brain surgery is a complicated business, requiring utmost precision when excising tumors and other maladies. BrainCarta, a Dutch firm, is showing off its Elonav technology that uses functional magnetic resonance imaging (fMRI) scans to create maps of lesions and provide helpful analysis about the nearby anatomy.
The firm believes that Elonav can help surgeons perform ever more difficult procedures, remove more diseased tissue, and improve intraoperative efficiency.
We got a chance to learn more about the technology at the Holland booth of CES 2019:

Are We Ready for MRI That Can Detect the Human Soul?
What initially reeked of fake news has now been proven real: theShenzhen Institutes of Advanced Technology has invested $126 million to build a magnetic resonance imaging (MRI) scanner to identify the human soul.According to news sources, the scanner will produce a resolution that ’s 1,000 times more powerful than conventional MRI and will be able to image objects that are 1 millimeter wide. The researchers’ ambitions know no limits, and as one unnamed scientist said,“We may for the first time capture a full picture of human consciousness or even the essence of life itself. Then we can define them and explain how th...

15-Minute MRI Coming Out of the University of Arizona
Researchers at the University of Arizona ’s College of Engineering are reducing magnetic resonance imaging (MRI) scan time to 15 minutes by using multiplexed sensitivity-encoding (MUSE), a technology that eliminates many of the time-consuming elements of MRI.The group of researchers led by Nan-kaei Chen, PhD, associate professor of biomedical engineering, were awarded a $2.1 million grant from theNational Institute of Neurological Disorders and Stroke to create faster MRI scans that will be beneficial to patients who struggle to lay still in the machine for 40 minutes to an hour. The five- year project specifically targe...
