In order to sustain fast growth, cancer cells need to take up nutrients at a faster rate than healthy cells. The human glutamine transporter ASCT2 allows the amino acid glutamine to enter cells and is upregulated in many types of cancer cells, which need more glutamine. It is a potential target for new anti-cancer drugs. Researchers at the University of Groningen have now elucidated a structure of the human ASCT2 that provides unprecedented insight in the workings of this protein, and may help the development of drugs.
Materials with controlled porosity have found diverse applications in separation, catalysis, energy storage, sensors and actuators, tissue engineering and drug delivery. Multiple methods have been developed to fabricate well-defined porous materials with the pore sizes ranging from nanometers to millimeters. For example, the introduction of sacrificial templates can impart porosity to the materials encapsulating them after the removal of embedded materials.
A ground-breaking device to help patients with dizziness problems has moved a step forward following a successful research study.
Researchers from UEA and the Norfolk and Norwich University Hospital (NNUH) have published the results of the biggest collection of continuous eye movement data after testing the effectiveness of a wearable diagnostic headset.
The Continuous Ambulatory Vestibular Assessment (CAVA) aims to speed up the diagnosis of the most common causes of dizziness.
Engineers have for the first time created a simulator mimicking the mechanical behaviour of the human torso - which could lead to innovations in the design of medical back supports.
It allows researchers to test different back brace designs and configurations without needing to test them on people - removing significant logistical and ethical issues.
"Dangerous Pastures: Deadly Grass Puts Horses at Risk" - Such dire warnings on the websites of horse owners and horse lovers may cause people to see their environment in a whole new light. Because what they once considered the epitome of pristine nature, green meadows of grass gently swaying in the wind, is actually home to numerous toxic substances that can be lethal for horses, cattle and sheep.
Researchers in the Academic Unit of Neurology at Trinity College Dublin have identified characteristic changes in the patterns of electrical brain wave activity in motor neurone disease (MND). This ground breaking observation will help to develop treatments for the disease that affects over 350 people in Ireland.
A Rutgers-led team of surgeons developed a groundbreaking procedure based on a century-old plastic surgery technique, to save the life of a patient who suffered complications following the removal of a cancerous tumor inside his skull.
More than a tenth of adults age 65 and older currently binge drink, putting them at risk for a range of health problems, according to a study by researchers at NYU School of Medicine and the Center for Drug Use and HIV/HCV Research (CDUHR) at NYU College of Global Public Health.
The study, published in the Journal of the American Geriatrics Society, also finds certain factors--including using cannabis and being male--are associated with an increase in binge drinking.
A team of researchers led by members of the University of Colorado School of Medicine at the Anschutz Medical Campus found that choline, an essential micronutrient, can prevent fetal brain developmental problems that can occur when mothers use marijuana while pregnant.
The findings are critical because marijuana use can negatively impact fetal brain development and early childhood behavior, such as increased impulsivity and memory dysfunction.
The study was published today in Psychological Medicine.
SOLOMONS, MD (July 30, 2019)--Scientists from the University of Maryland Center for Environmental Science are predicting that warmer winters in the Chesapeake Bay will likely lead to longer and more productive seasons for Maryland's favorite summer crustacean, the blue crab.
Researchers examined data on increasing temperatures in the Chesapeake Bay and predictions for continued warming. They found that winters will be up to 50% shorter by 2100, and overwinter survival of the blue crab will increase by at least 20% compared to current conditions.
COLUMBUS, Ohio - Loneliness and social anxiety is a bad combination for single people who use dating apps on their phones, a new study suggests.
Researchers found that people who fit that profile were more likely than others to say they've experienced negative outcomes because of their dating app use.
"It's not just that they're using their phone a lot," said Kathryn Coduto, lead author of the study and doctoral student in communication at The Ohio State University.
Ketamine has gotten a bad rap as an opioid when there's plenty of evidence suggesting it isn't one, Johns Hopkins experts say. They believe this reputation may hamper patients from getting necessary treatment for the kinds of depression that don't respond to typical antidepressants. In a new paper, the researchers clarify the mechanism behind ketamine's mechanism of action in hopes of restoring the therapy's standing among health care professionals and the public.
In March of this year, the U.S. Food and Drug Administration approved ketamine as a nasal spray to treat depression.
TORONTO, July 31, 2019 -- Palaeontologists at the Royal Ontario Museum and University of Toronto have uncovered fossils of a large new predatory species in half-a-billion-year-old rocks from Kootenay National Park in the Canadian Rockies. This new species has rake-like claws and a pineapple-slice-shaped mouth at the front of an enormous head, and it sheds light on the diversity of the earliest relatives of insects, crabs, spiders, and their kin. The findings were announced July 31, 2019, in a study published in Proceedings of the Royal Society B.
New cases of tick-borne Lyme disease in the UK may be three times higher than previous estimates suggest, and might top 8000 in 2019, based on these figures, concludes research published in the online journal BMJ Open.
Lyme disease is a bacterial (Borrelia) infection passed on through the bite of an infected tick. It has become the most common tick-borne infection in many parts of Europe and the USA.
A new study reveals that school fitness tests have little impact on student attitudes to PE - contrary to polarised views on their merits - and for many students, fitness testing during PE may be wasting valuable class time when used in isolation from the curriculum.
