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.

3D replicas of healthy adult hearts show how cardiac shape relates to function

Researchers from King's College London have created 3D replicas of full-sized healthy adult hearts from Computed Tomography (CT) images and analyzed how cardiac shape relates to function.

Researchers provide ultrastructural details of SARS-CoV-2-infected respiratory epithelial cells

A team of scientists from the United Kingdom recently investigated the ultrastructural details of the attachment, entry, and budding processes of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) in the human airway epithelium. They have used a highly differentiated air-liquid interface cultures of airway epithelium to thoroughly investigate the viral infection cycle. The study is currently available on the bioRxiv* preprint server.

Oxford-AstraZeneca COVID vaccine induces cell spikes similar to SARS-CoV-2's

Scientists from the University of Oxford and the University of Southampton report in the journal ACS Central Science that cells infected with the ChAdOx1 vaccine produce spike proteins on the cells similar to those produced by natural SARS-CoV-2 infection.

Scientists produce high-resolution 3D image of sarcomere using electron cryo-tomography

Scientists have produced the first high-resolution 3D image of the sarcomere, the basic contractile unit of skeletal and heart muscle cells, by using electron cryo-tomography (cryo-ET).

Researchers evaluate human performance in 2D and 3D localization tasks

Three-dimensional or "volumetric" images are widely used in medical imaging. These images faithfully represent the 3D spatial relationships present in the body. Yet 3D images are typically displayed on a two-dimensional monitor, which creates a dimensionality mismatch that must be resolved in a clinical setting where practitioners must search a 2D or a 3D image to find a particular trait or target of interest.

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.

New AI platform can help assess vascular diseases

An international team of scientists from Nanyang Technological University, Singapore (NTU Singapore), Brown University and the Massachusetts Institute of Technology (MIT) has developed an artificial intelligence (AI) platform that could one day be used in a system to assess vascular diseases, which are characterised by the abnormal condition of blood vessels.

Maintaining a stable body weight does not reduce risk of death in colorectal cancer survivors

Colorectal cancer survivors who maintained a stable body weight but lost muscle and developed fatty deposits in their muscles faced a 40 percent higher risk of premature death than patients who avoided both health issues.

Immediate angiography for stroke patients linked to improved recovery, less disability

Immediate angiography, rather than the standard computed tomography (CT scan), reduced stroke treatment time and was linked to improved recovery, according to late-breaking science presented today at the American Stroke Association's International Stroke Conference 2021.

COVID-19 is more difficult to diagnose in children and adolescents, finds study

The ongoing pandemic of coronavirus disease 2019 (COVID-19), caused by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), has spread to over 192 countries and territories, causing an enormous loss of lives and economic devastation.
