A new tool called CORAL guides clinicians through diagnostic evaluations of patients with COVID-19 symptoms, allowing for safe discontinuation of isolation. The tool was developed to minimize the chance of false-negative test results and reduce hospitalization time.
Researchers found that vegetables in U.S. Department of Agriculture's 'dark green' category were often included in product names, but their average order in the ingredient list was close to fourth. Fruits, particularly juice and juice concentrates, were less likely to appear in product names despite being more prominent in the ingredie...
Scientists at RIKEN Center for Biosystems Dynamics Research have identified a population of hair follicle stem cells and developed a recipe for normal cyclical regeneration. In the study, 81% of bioengineered hair follicles generated in NFFSE medium went through at least three hair cycles and produced normal hair.
Scientists observed disulphide bridge formation in ribosomal exit tunnel during protein synthesis, challenging previous assumptions. The discovery sheds new light on the causes of lens opacities and cataracts, a leading cause of vision loss worldwide.
A new study by researchers from Linköping University suggests that long-term stress is a risk factor for heart attacks. Cortisol levels in hair samples were found to be statistically significantly higher in individuals who suffered a heart attack, even after adjusting for other cardiovascular risk factors.
A single strain of Bacteroides fragilis significantly reduced graft-versus-host disease by protecting gut integrity, according to a proof-of-concept study. The bacteria increased overall gut microbial diversity and reduced donor T cell proliferation, which triggers GVHD.
A new study published in Diabetes Care found that children with Type 1 Diabetes have lower brain volumes and IQ scores compared to non-diabetic children. The research suggests that hyperglycemia may adversely affect brain development, starting from childhood.
