Rather than a slow build-up of plaque over time, a heart attack caused by spontaneous coronary artery dissection strikes suddenly, often in younger women who didn't seem to be at risk for a cardiac event.
SCAD is poorly understood, and it's so far impossible to predict which combination of genes and environmental triggers will lead coronary arteries to spontaneously tear, or dissect, leading to a heart attack that requires emergency, life-saving medical care.
Researchers at Karolinska Institutet in Sweden have identified a small neutralizing antibody, a so-called nanobody, that has the capacity to block SARS-CoV-2 from entering human cells. The researchers believe this nanobody has the potential to be developed as an antiviral treatment against COVID-19. The results are published in the journal Nature Communications.
What's the risk of different human populations to develop a disease? To find out, a team led by Université de Montréal professor Guillaume Lettre created an international consortium to study the blood of hundreds of thousands of people worldwide.
In one of the largest studies of its kind, published today in Cell, close to 750,000 participants from five major populations -- European, African, Hispanic, East Asian and South Asian -- were tested to see the effect of genetic mutations on characteristics in their blood.
The path to global sustainability isn't a one-way street and scientists at Michigan State University and in China use the world's adoration of pandas to show new ways to figure out how not to get lost.
Pregnant mice fed a diet high in omega-6 fats and low in omega-3 fats produce offspring that go on to exhibit "hedonic"--pleasurable but excessive--levels of consumption of hyper-caloric diets, according to researchers at Hiroshima University.
Omega-6 fats are found in grapeseed oil, corn oil and sesame oil, and are a staple of several salad dressings in world cuisine. Omega-3 fats are found in fish, perilla oil, and linseed oil. A diet balanced with these fats is considered essential for healthy brain growth.
(LOS ANGELES) - In a newly published paper, the authors first paint the vision of what optimal patient advocacy can do to overcome the challenges described by kidney transplant patients and donors, and then describe how to make that vision a reality, especially during the COVID-19 pandemic. Dr. Amy Waterman, Deputy Director at the Terasaki Institute for Biomedical Innovation and leader of the Transplant Research and Education Center (TREC), assembled a panel of patients to learn their priorities for their care during this unprecedented time.
Co-author, Senior Research Associate of the KFU Quantum Informatics Lab Kamil Khadiev, explains, "The Dyck problem is designed to check the program code and allows you to find out whether it satisfies the rules or not. The problem, on the one hand, is an important subtask of parsers and compilers, and on the other hand, it is interesting from a theoretical point of view. The classical solution to the problem has been known for a long time, but no one thought about a quantum algorithm for the problem until 2018.
In 2019, the number of registered campylobacter infections increased by almost a fifth and studies show that many of the campylobacter outbreaks recorded that year were caused by chicken meat. These are some of the findings from the annual report on the incidence of zoonoses in Denmark for 2019.
There are good reasons to be worried about indoor air quality right now, in light of COVID-19. In addition to transmitting infectious agents, indoor spaces can also be a source of harmful chemicals in consumer products. A new analysis of indoor spaces on college campuses finds dust in classrooms and lecture halls harbors high levels of toxic flame retardants used in furniture raising health concerns from everyday exposures.
PITTSBURGH, Sept. 3, 2020 - Especially in settings where personal protective equipment, or PPE, is in short supply, intubation -- inserting a breathing tube down a patient's throat -- poses a major risk of SARS-CoV-2 exposure for doctors and nurses as viral particles are released into the air.
Since the start of the COVID-19 pandemic, there has been empirical and anecdotal reports of declines in both emergency and ambulatory medical visits. However, little research has been conducted to identify why these declines have occurred. New research now shows a strong association between mental health symptoms and medical care avoidance.
TORONTO (Sept. 3, 2020) -- The use of tear gas -- particularly CS gas -- as a riot control agent, cannot be reconciled with respect for fundamental human rights and should therefore be banned entirely in international law, the University of Toronto's International Human Rights Program (IHRP) says in a report released today.
(Vienna, 03 September 2020) Studies have indicated that people who dye their hair regularly may have a higher risk of cancer, especially bladder cancer and breast cancer. Hair dyes contain certain chemicals that have been held responsible for these relationships. In the largest study to date, which followed 117,200 women from the USA over 36 years, this could not be confirmed.
In the past century, neuroscientists have discovered various functional classes of neurons that are relevant to cognitive functions of the brain. These include orientation selective cells, place cells, grid cells and fear memory engram cells.
