BUFFALO, N.Y. - To improve the development of new saliva-based diagnostic tests and personalized medicine, the National Institute of Dental and Craniofacial Research (NIDCR) has supported the development of the Human Salivary Proteome Wiki, the first public platform that catalogs and curates data on each of the thousands of proteins within our saliva.
Scientists from the UK's University of Bath explore racemases - an important type of enzyme that is linked to certain cancers and other life-threatening diseases while also being critical to cell function - in a paper published in the prestigious journal Chemical Society Reviews. The scientists also propose new strategies for finding drugs that neutralise these enzymes.
An international and multidisciplinary team led by researchers at the University of Oxford, University of Glasgow, and University of Heidelberg, has uncovered the interactions that SARS-CoV-2 RNA establishes with the host cell, many of which are fundamental for infection. These discoveries pave the way for the development of new therapeutic strategies for COVID-19 with broad-range antiviral potential.
Alzheimer's disease is the main cause of dementia and current therapeutic strategies cannot prevent, slow down or cure the pathology. The disease is characterized by memory loss, caused by the degeneration and death of neuronal cells in several regions of the brain, including the hippocampus, which is where memories are initially formed. Researchers from the Netherlands Institute for Neuroscience (NIN) have identified a small molecule that can be used to rejuvenate the brain and counteract the memory loss.
New cells in old brains
Swedish and Danish journalists describe their role as monitorial to a greater extent than journalists from other Nordic countries. Journalists from Norway and Iceland state they have the least experience of political influence and thus differ from Finnish journalists. This is shown by a new comparative study published by Nordicom at the University of Gothenburg.
Over a year after the novel coronavirus cemented its grip on the world, much of the conversation surrounding the disease remains simple: how many people died and how many survived?
But researchers at Michigan Medicine say a devastating side effect lurks, underreported, between those extremes - the loss of ability caused by the virus.
Fusarium Head Blight (FHB), also known as scab, is a significant disease of small grain cereals, such as wheat and barley, that impacts farmers around the world. The disease has been reducing acreage and increasing the price of wheat production in the United States since the early 1990s, which in turn increases costs for downstream producers, such as millers and brewers.
What started as the preliminary analysis of routine laboratory data has since evolved into the largest-ever study of viral load levels in patients with SARS-CoV-2. A team of researchers from Charité - Universitätsmedizin Berlin have now analyzed the PCR samples of more than 25,000 persons with COVID-19. Working under the leadership of Prof. Dr. Christian Drosten, the team determined the viral loads of each individual sample and used their results to estimate levels of infectiousness.
LA JOLLA--(May 25, 2021) One of the many effects of aging is loss of muscle mass, which contributes to disability in older people. To counter this loss, scientists at the Salk Institute are studying ways to accelerate the regeneration of muscle tissue, using a combination of molecular compounds that are commonly used in stem-cell research.
"If you build it, they will come," so says the idiom but it's the storytellers, knowledge-makers and an "agentic" or open-minded population who help create great entrepreneurial cities.
A new research study, conducted by QUT, RMIT and the University of Indiana, analysed data from 362 American cities with a focus on human agency, entrepreneurial spirit, and economic growth.
The study, based on geographic psychological profiles of millions of people based in the US, found people and an empowered city life matter in shaping urban vitality.
Feeling anxious can direct our attention and memory toward supernatural beings such as gods, a University of Otago study has found.
Lead author Dr Thomas Swan, of the Department of Psychology, says the research may help explain how religious beliefs are formed.
For the study, published in the International Journal for the Psychology of Religion, 972 participants completed an online recall test to determine if a bias to recall supernatural agents was stronger in anxious people, rather than non-anxious people.
SILVER SPRING, Md.--People who are successful at weight-loss maintenance spend less time sitting during the week and weekends compared to weight-stable individuals with obesity, according to a paper published online in Obesity, The Obesity Society's flagship journal. This is the first study to examine time spent in various sitting activities among weight-loss maintainers.
While many might consider a walk in the woods to be a quiet, peaceful escape from their noisy urban life, we often don't consider just how incredibly noisy some natural environments can be. Although we use soothing natural sounds in our daily lives - to relax or for meditation - the thunder of a mountain river or the crash of pounding surf have likely been changing how animals communicate and where they live for eons. A new experimental study published in the journal Nature Communications finds that birds and bats often avoid habitat swamped with loud whitewater river noise.
Despite a daunting more than 130 million cases of SARS-CoV-2 infections to date worldwide, another global pathogen - the Aedes mosquito-borne dengue virus - saw a record number of over 400 million cases in 2019. But vaccine development has been challenging due to the need to protect equally against all four dengue strains. The discovery of new possible biomarkers to predict clinical and immune responses to dengue virus infection, published today in Nature Communication, could be critical to informing future vaccines.
Within the European Union alone, about three million people are affected by an autism spectrum disorder (ASD). Some are only mildly affected and can live independent lives. Others have severe disabilities. What the different forms have in common is difficulty with social interaction and communication, as well as repetitive-stereotypic behaviors. Mutations in a few hundred genes are associated with ASD. One of them is called Cullin 3, and it is a high-risk gene: A mutation of this gene almost certainly leads to a disorder. But how exactly does this gene affect the brain?
