Antiviral effects of honeysuckle decoction affected in SIDT1poly population

Previously, Chen-Yu Zhang's group have identified SID1 transmembrane family member 1 (SIDT1) as a critical membrane protein mediating dietary miRNAs absorption, which is abolished in SIDT1 deficient mice.

A new approach to study the role of Neandertal DNA during development

Protocols that allow the transformation of human induced pluripotent stem cell (iPSC) lines into organoids have changed the way scientists can study developmental processes and enable them to decipher the interplay between genes and tissue formation, particularly for organs where primary tissue is not available.

Seroconversion marks recovery from COVID-19

Nine months into the COVID-19 pandemic, scientists are still seeking to understand the protective immunity that develops against the causative agent severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). Despite the increasing need for serological tests in epidemiology, their clinical value has not been fully established. A new paper published in the Journal of Medical Virology in September 2020 describes the relationship of COVID-19 disease symptoms with the serological status over time.

Daily outdoor lessons in green spaces can boost self-regulation in young children

Amid one of the strangest back-to-school seasons in modern history, many teachers, parents, and caregivers are struggling to enrich their students' experiences beyond screen-based learning.

Study compares clinical outcomes of Ellipsys and WavelinQ-4F pAVF devices

Two devices for creating minimally invasive dialysis access--the Ellipsys® Vascular Access System and the WavelinQ™ 4F System--demonstrated high rates of technical success and low rates of complications, according to a new study published in the Journal of Vascular and Interventional Radiology.

Researchers say Influenza may increase risk of COVID-19

A recent study by researchers suggests that the spread of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is influenced by influenza virus infection during the initial period of coronavirus disease 2019 (COVID-19) pandemic in Europe. The study is currently available on the medRxiv preprint server.

New radio-frequency-based system to monitor a person's sleep postures

MIT researchers have developed a wireless, private way to monitor a person's sleep postures -- whether snoozing on their back, stomach, or sides -- using reflected radio signals from a small device mounted on a bedroom wall.

Migraine patients may benefit from green light therapy

New research from the University of Arizona Health Sciences found that people who suffer from migraine may benefit from green light therapy, which was shown to reduce the frequency and intensity of headaches and improve patient quality of life.

Researchers identify DNA activation code using artificial intelligence

Scientists have long known that human genes spring into action through instructions delivered by the precise order of our DNA, directed by the four different types of individual links, or "bases," coded A, C, G and T.

Dyslexia deficits could be improved with non-invasive brain stimulation

Dyslexia is a frequent disorder of reading acquisition that affects up to 10% of the population, and is characterised by lifelong difficulties with written material.

Host gene editing main driving force of SARS-CoV-2 mutations

A new study published on the aRxiv preprint server in September 2020 shows that the host immune response, mediated by two RNA editors, causes the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) to adapt and change strain characteristics.

Study reveals partially overlapping patterns of brain function in people with anorexia and body dysmorphic disorder

A new UCLA study shows partially overlapping patterns of brain function in people with anorexia nervosa and those with body dysmorphic disorder, a related psychiatric condition characterized by misperception that particular physical characteristics are defective.

'Molecular brake' on the immune system could be potential treatment target for severe COVID-19

Older people and people with underlying medical conditions are at particular risk of severe COVID-19. A group of researchers from Charité - Universitätsmedizin Berlin have discovered one possible reason for this vulnerability.

Study reveals how brain waves may control flow of information throughout the cortex

To produce your thoughts and actions, your brain processes information in a hierarchy of regions along its surface, or cortex, ranging from "lower" areas that do basic parsing of incoming sensations to "higher" executive regions that formulate your plans for employing that newfound knowledge

Memory B cells indicate durable immunity in COVID-19

Now a new study by researchers at SUNY Upstate Medical University and published recently on the preprint server medRxiv in September 2020 shows that memory B cells are upregulated in convalescent COVID-19 patients, correlating with a better immune response and shorter symptom duration.

Computer model can replicate the unique firing-rate dependent behavior of Purkinje neurons

Research conducted by the Computational Neuroscience Unit at the Okinawa Institute of Science and Technology Graduate University has shown for the first time that a computer model can replicate and explain a unique property displayed by a crucial brain cell.

The T cell responses in COVID-19 recovered individuals

A recent study demonstrates that functional CD4+ and CD8+ T cells specifically targeting the entire proteome of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) remain active in individuals who have recovered from severe or mild coronavirus disease 2019 (COVID-19). Moreover, the magnitude of T cell response is correlated with the antibody response. The study is published in the journal Nature Immunology.
