MINNEAPOLIS, MN- June 3, 2020 - Today, University of Minnesota Medical School researchers published the results from the first randomized clinical trial testing hydroxychloroquine for the post-exposure prevention of COVID-19.
Alcohol-related liver disease is currently the most common reason for liver transplantation in the United States. In recent years, high-risk drinking of alcohol--defined as exceeding daily drinking limits (more than 4 or 5 standard drinks for women and men, respectively) at least weekly for a whole year--has increased in nearly all sociodemographic groups, especially in women.
University of Melbourne researchers are finding ways to beat dangerous superbugs with 'resistance resistant' antibiotics, and it could help in our fight against coronavirus (COVID-19) complications.
As bacteria evolve, they develop strategies that undermine antibiotics and morph into 'superbugs' that can resist most available treatments and cause potentially lethal infections.
The proportion of Australians with bad cholesterol levels has dropped significantly, while Asian and Pacific countries recorded a sharp rise, according to the world's largest study on the condition.
University of Queensland researchers were part of an international team that analysed data from 102.6 million people in 200 countries, spanning the period from 1980 to 2018.
Researchers at Wake Forest School of Medicine have discovered that nicotine promotes the spread of lung cancer cells into the brain, where they can form deadly metastatic tumors. The study, which will be published June 4 in the Journal of Experimental Medicine (JEM), suggests that nicotine replacement therapies may not be suitable strategies for lung cancer patients attempting to quit smoking.
WASHINGTON -- Neurodegenerative diseases such as Alzheimer's and Parkinson's are often accompanied by amyloid proteins in the brain that have become clumped or misfolded. A newly developed technique that measures the orientation of single molecules is enabling optical microscopy to be used, for the first time, to reveal nanoscale details about the structures of these problematic proteins.
Researchers from Washington University in St. Louis describe their new approach in Optica, The Optical Society's journal for high impact research.
Meningococci are bacteria that can cause life-threatening meningitis and sepsis. These pathogens use a small protein with a large impact: The RNA-binding protein ProQ is involved in the activation of more than 250 bacterial genes.
ProQ ensures that meningococci can better repair their DNA if damaged and it makes them resistant to oxidative stress. Both these factors contribute significantly to the bacteria's pathogenic properties.
Physicists have created the most sensitive strain sensor ever made, capable of detecting a feather's touch.
The sensor, developed by the Materials Physics Group at the University of Sussex, can stretch up to 80 times higher strain than strain gauges currently on the market and show resistance changes 100 times higher than the most sensitive materials in research development.
The research team believe the sensors could bring new levels of sensitivity to wearable tech measuring patients' vital signs and to systems monitoring buildings and bridges' structural integrity.
CHAMPAIGN, Ill. -- Researchers report that the Asian tiger mosquito, Aedes albopictus, has become more abundant across Illinois in the past three decades. Its spread is problematic, as the mosquito can transmit diseases - like chikungunya or dengue fever - to humans.
The Asian tiger mosquito originated in the forests of southeast Asia. It found its way to Texas around 1985 and very quickly spread to Illinois.
WEST LAFAYETTE, Ind. - A Purdue University data science and machine learning innovator wants to help organizations and users get the most for their money when it comes to cloud-based databases. Her same technology may help self-driving vehicles operate more safely on the road when latency is the primary concern.
Somali Chaterji, a Purdue assistant professor of agricultural and biological engineering who directs the Innovatory for Cells and Neural Machines [ICAN], and her team created a technology called OPTIMUSCLOUD.
PHILADELPHIA -- Young patients with no risk factors for stroke may have an increased risk if they have contracted COVID-19, whether or not they are showing symptoms of the disease. Surgeons at Thomas Jefferson University and collaborators analyzed patients presenting with stroke from March 20th until April 10th at their institutions. The strokes they observed were unlike what they usually see.
LA JOLLA--(June 4, 2020) Cancer is often the result of DNA mutations or problems with how cells divide, which can lead to cells "forgetting" what type of cell they are or how to function properly. Now, Professor Martin Hetzer and a team of scientists have provided clarity into how new cells remember their identity after cell division. These memory mechanisms, published in Genes & Development on June 4, 2020, could explicate problems that occur when cell identity is not maintained, such as cancer.
A team of scientists from Stanford University is working with researchers at the Molecular Foundry, a nanoscience user facility located at the Department of Energy's Lawrence Berkeley National Laboratory (Berkeley Lab), to develop a gene-targeting, antiviral agent against COVID-19.
You are alone on a small sailing boat, more than four thousand miles of ocean ahead and you are up against approximately 80 sailors. It will take you three or four weeks to get to the finishing line. But how will you manage to sleep and which sleeping strategy will pay off during the race? For the first time, a group of researchers of the University of Bologna identified and analysed the different sleeping strategies employed by solo skippers.
Researchers have uncovered a link between the structure of the protein alpha-synuclein and its likelihood to misfold and aggregate.
Alpha-synuclein aggregates are the hallmark of neurodegenerative disorders, such as Parkinson's disease. Their findings, published today in Nature Communications, identify potential new therapeutic targets in the treatment of Parkinson's disease.
