LA JOLLA--(March 31, 2021) Clinicians using a new viral screening test can not only diagnose COVID-19 in a matter of minutes with a portable, pocket-sized machine, but can also simultaneously test for other viruses--like influenza--that might be mistaken for the coronavirus. At the same time, they can sequence the virus, providing valuable information on the spread of COVID-19 mutations and variants. The new test, dubbed NIRVANA, was described online today by a multi-institution team of scientists in the journal Med.
AURORA, Colo. (March 31, 2021) - A new study published in Frontiers in Psychiatry finds that patients with Obsessive Compulsive Disorder (OCD) as well as other psychiatric comorbidities, such as autism spectrum or tic disorders, may respond well to Deep Brain Stimulation (DBS).
The pandemic is affecting every country, but not every country has equal access to the lifesaving COVID-19 vaccines. Recent estimates show that high-income countries -- which have just one-fifth of the global adult population -- have purchased more than half of the world's total vaccine doses, resulting in disparities for low- and middle-income countries.
Obesity rates have increased dramatically in developed countries over the past 40 years -- and many people have assumed that food marketing is at least in part to blame. But are people with obesity really more susceptible to food marketing? And if they are, is that a permanent predisposition, or can it change over time?
Oak Brook, IL - The April edition of SLAS Technology features the cover article "Therapeutic Potential of Reactive Oxygen Species: State of the Art and Recent Advances" by Valeria Graceffa, Ph.D. (Institute of Technology Sligo, Sligo, Ireland).
NEW YORK, NY (March 30, 2021)--Early in the pandemic, neurologists expressed concern that COVID-19 patients with dementia may be at higher risk for complications and mortality.
Not all species may travel the same path to existence, at least according to new findings from the University of Colorado Boulder and collaborators.
This new research, out now in Science, looked at a newly discovered, endangered songbird located only in South America--the Iberá Seedeater--and found that this bird followed a very rare evolutionary path to come into existence at a much faster pace than the grand majority of species.
Scientists have discovered a new genetic disease, which causes some children's brains to develop abnormally, resulting in delayed intellectual development and often early onset cataracts.
The majority of patients with the condition, which is so new it doesn't have a name yet, were also microcephalic, a birth defect where a baby's head is smaller than expected when compared to babies of the same sex and age.
Researchers from the universities of Portsmouth and Southampton found that changes in a gene called coat protein complex 1 (COPB1) caused this rare genetic disease.
A new study examining how people with severe and profound intellectual disabilities resist activities while in care recommends that institutions improve training to help carers better understand non-verbal cues, as well as offer greater flexibility to allow individual preferences to take priority over institutional schedules.
University of California, Irvine, biologists have discovered that plants influence how their bacterial and fungal neighbors react to climate change. This finding contributes crucial new information to a hot topic in environmental science: in what manner will climate change alter the diversity of both plants and microbiomes on the landscape? The paper appears in Elementa: Sciences of the Anthropocene.
The human brain regions responsible for speech and communication keep our world running by allowing us to do things like talk with friends, shout for help in an emergency and present information in meetings.
However, scientific understanding of just how these parts of the brain work is limited. Consequently, knowledge of how to improve challenges such as speech impediments or language acquisition is limited as well.
Osaka, Japan - Streptococcus pyogenes is one of the most important bacterial causes of human skin infections. If S. pyogenes invades deep into the tissue, it can cause life-threatening illnesses, such as sepsis and toxic shock. With its limited supply of carbohydrates, the skin is generally an effective barrier against infection and not a good surface for the survival of S. pyogenes. To survive successfully and invade deep into the tissue, bacteria must be able to find a source of nutrients and also evade the skin's immune defenses.
Scientists from Tomsk Polytechnic University jointly with Russian colleagues and researchers from Technical University of Denmark the first time have experimentally proved the existence of a two-dimensional (2D) curved flux of plasmonic quasiparticles, a plasmonic hook. A flat 2D hook is smaller than a 3D hook and possesses new properties, due to them, the researchers consider it as the most promising transmitter in high-speed microoptical circuits. The research findings are published in Applied Physics Letters (IF: 3,597; Q1) academic journal.
Researchers from Queen Mary University of London have shown for the first time that animal DNA shed within the environment can be collected from the air.
The proof-of-concept study, published in the journal PeerJ, opens up potential for new ecological, health and forensic applications of environmental DNA (eDNA), which to-date has mainly been used to survey aquatic environments.
Key Points
The PURE study is the first multinational study exploring the association between unprocessed and processed meat intakes with health outcomes in low-, middle-, and high-income countries.
The consumption of unprocessed red meat and poultry was not found to be associated with mortality nor major cardiovascular disease events.
In contrast, higher processed meat intake was associated with higher risks of both total mortality and major cardiovascular disease.
