Executive control differences in autism may be the result of a unique approach A new study by UC Davis MIND Institute researchers suggests that executive control differences in autism spectrum disorder (ASD) may be the result of a unique approach, rather than an impairment. Executive control difficulties are common in individuals with autism and are associated with challenges completing tasks and managing time. The study, published in Biological Psychiatry: Cognitive Neuroscience and Neuroimag...

Sound sleep plays a crucial role in healing traumatic brain injuries Sound sleep plays a critical role in healing traumatic brain injury, a new study of military veterans suggests. The study, published in the Journal of Neurotrauma, used a new technique involving magnetic resonance imaging developed at Oregon Health & Science University. Researchers used MRI to evaluate the enlargement of perivascular spaces that surround blood vessels in the brain. Enlargement of these spaces occurs in aging ...

Researchers explore brain network differences between autistic and neurotypical control males and females Around three times as many males are diagnosed with autism than females. This suggests that biological sex factors may play a role in the development and presentation of autism. Studies on the neurobiology (brain biology) of males and females with autism have begun to examine brain networks but results have been mixed. This is largely due to the limited availability of data from autistic fe...

email article Soon after intervention for an MI, remaining high-risk vulnerable plaques can be identified from catheter-based imaging, according to a natural history study. Most of the 13.22% of major cardiac events that happened over 4 years among a cohort of 898 MI survivors stemmed from untreated lesions deemed angiographically benign and non-flow-limiting at the time of the index MI, reported the PROSPECT II team led by David Erlinge, MD, PhD, of Lund University in Sweden, in the Marc...

New high-performance, safe MRI contrast agent for 3D vascular mapping Heart attack and stroke are the first and second leading causes of death in developed countries, respectively. As the disease often results in sudden death with few special prognostic symptoms, early diagnosis is very important. For this purpose, imaging techniques such as magnetic resonance imaging (MRI) are widely used to identify the narrowing or blockage of blood vessels. In MRI, contrast agents improve the visibility of ...

Sectra signs five-year enterprise imaging contract with Emory Healthcare in the US International medical imaging IT and cybersecurity company Sectra (STO: SECT B) will install its enterprise imaging solution at Atlanta-based, Emory Healthcare. The contract, signed in February, includes modules for radiology and all imaging subspecialties, orthopedics, and image archiving. Patient linking will be set up with sister institution, Grady Health System, to ensure physicians at both locations have ac...

Silent heart attacks appear to increase future stroke risk in older adults Silent heart attacks appear to increase stroke risk in adults 65 and older, according to preliminary research to be presented at the American Stroke Association International Stroke Conference 2021. The virtual meeting is March 17-19, 2021 and is a world premier meeting for researchers and clinicians dedicated to the science of stroke and brain health. A silent heart attack, also known as a silent myocardial infarction, ...

To address the need for a high-quality neutralization assay against SARS-CoV-2, researchers from the NIAID modified and optimized a previously established fluorescence reduction neutralization assay (FRNA) to provide a quantitative assessment of a large number of infected cells through the use of a high-content imaging system.

Pictures of the retina may someday provide early warning signs that a person is at an increased risk of stroke and dementia, making it possible to take preventive measures, according to preliminary research to be presented at the American Stroke Association's International Stroke Conference 2021.

Size matters: Bimodal imaging receives nanoparticle enhancement A nanoparticles size is fine-tuned to offer high-resolution images before and during surgical procedures. Tsukuba, Japan, Mar 10, 2021 - (ACN Newswire) - Scientists have found a way to control the size of special nanoparticles to optimize their use for both magnetic resonance and near-infrared imaging. Their approach could help surgeons use the same nanoparticles to visualize tumours just before and then during surgery using the tw...
