Researchers at the University of Eastern Finland have discovered previously unknown non-coding RNAs (ncRNAs) involved in regulating the gene expression of vascular endothelial growth factors (VEGF), the master regulators of angiogenesis.
Penn Medicine researchers used microscopy and machine learning to distinguish tau protein aggregates occurring as part of healthy functions from those occurring in disease.
Magnetic Resonance Imaging (MRI) images are usually meant to be static. But now, researchers from Mātai Medical Research Institute (Mātai), Stevens Institute of Technology, Stanford University, the University of Auckland and other institutions, report on an imaging technique that captures the brain in motion in real time, in 3D and in stunning detail, providing a potential diagnostic tool for detecting difficult-to-spot conditions such as obstructive brain disorders and aneurysms - before they become life threatening.
In this latest press release from the Imperial Brands Science website, we detail how our researchers developed an advanced 3D lung tissue model, leading to the first peer-reviewed vaping study evaluating repeated cigarette smoke and aerosol exposure. Results showed minimal effects to lung tissue from vape aerosol compared to cigarette smoke.
Larger bumblebees are more likely to go out foraging in the low light of dawn, new research shows.
A study published in July 2020 hypothesized a link between bradykinin, a well-known peptide, and severe cases of COVID-19. TTUHSC's Vardan Karamyan, Ph.D., found the article intriguing because it discussed bradykinin, one of three specific peptides with which his lab has much experience. In a focused review published in March by Physiological Reports, Karamyan suggests two other bioactive peptides also may be involved in the same processes and mechanisms proposed in the original paper.
Mammals see with their eyes, hear with their ears and smell with their nose. But which sense or organ allows them to orient themselves on their migrations, which sometimes go far beyond their local foraging areas and therefore require an extended ability to navigate? Scientific experiments led by the Leibniz Institute for Zoo and Wildlife Research (Leibniz-IZW) ) now show that the cornea of the eyes is the location of such an important sense in migrating bats.
Current guidelines for managing osteoporosis specifically call out hip or spine fractures for increasing the risk for subsequent bone breaks. But a new UCLA-led study suggests that fractures in the arm, wrist, leg and other parts of the body should also set off alarm bells. A fracture, no matter the location, indicates a general tendency to break a bone in the future at a different location,
A team led by Iain Drummond, Ph.D., of the MDI Biological Laboratory in Bar Harbor, Maine, has identified the signaling mechanisms underlying the formation of podocytes, which are tiny, highly specialized cells in the glomerulus, the cluster of blood vessels in the kidney where waste is filtered. The discovery opens the door to the development of therapies to replace or regenerate these cells, which are vital to ridding the body of toxins.
Despite increased use of repetitive transcranial magnetic stimulation in psychiatry, the rates at which patients respond to the therapy and experience remission of often-disabling symptoms have been modest at best. Now, a team of University of South Florida psychiatrists and biomedical engineers applied an emerging functional neuroimaging technology, known as diffuse optical tomography (DOT), to better understand how rTMS works so they can begin to improve the brain stimulation procedure's effectiveness in treating depression.
