Tuesday, 29 June 2021 - New research has shown that early testing for blood clots in patients who had received the AstraZeneca/Oxford vaccine led to them being treated successfully, highlighting the need for heightened awareness of the risk among doctors.
The work, led by researchers from RCSI University of Medicine and Health Sciences and the National Coagulation Centre at St James's Hospital, is published in the British Journal of Haematology.
The LSL60101 compound, a specific ligand of the I2-IR receptors in the brain, could shed light on the development of future strategies against Alzheimer's disease. This is stated in the recent studies by the Research Group on Medicinal Chemistry and Pharmacology of Neurodegenerative Diseases of the University of Barcelona, published in the journals European Journal of Medicinal Chemistry and British Journal Pharmacology. In studies carried out with mice, LSL60101 has improved the cognitive deficit and the biomarkers related to the disease in these animal models.
Six antibody characteristics could help scientists identify which pregnant women are at risk of placental malaria infections, finds a study published today in eLife.
New insight on how our experiences during a task or interaction shape our current mood has been published today in the open-access eLife journal.
The study suggests that early experiences may have a larger effect on our mood than more recent events. These findings hold implications for the timing of events in experimental or clinical settings, and suggest new directions for mood interventions tailored to individual patients.
Rising nighttime temperatures are curbing crop yields for rice, and new research moves us closer to understanding why. The study found that warmer nights alter the rice plant's biological schedule, with hundreds of genes being expressed earlier than usual, while hundreds of other genes are being expressed later than usual.
"Essentially, we found that warmer nights throw the rice plant's internal clock out of whack," says Colleen Doherty, an associate professor of biochemistry at North Carolina State University and corresponding author of a paper on the work.
A team of neuroscientists at the Beckman Institute for Advanced Science and Technology led by Baher Ibrahim and Dr. Daniel Llano published a study in eLife that furthers our understanding of how the brain perceives everyday sensory inputs.
ROCHESTER, Minn. -- Mayo Clinic researchers are taking a close look at rare cases of inflammation of the heart muscle, or myocarditis, in young men who developed symptoms shortly after receiving the second dose of the Moderna or Pfizer messenger RNA (mRNA) COVID-19 vaccines. Several recent studies suggest that health care professionals should watch for hypersensitivity myocarditis as a rare adverse reaction to being vaccinated for COVID-19. However, researchers stress that this awareness should not diminish overall confidence in vaccination during the current pandemic.
Using real-time deformability cytometry, researchers at the Max-Planck-Zentrum für Physik und Medizin in Erlangen were able to show for the first time: Covid-19 significantly changes the size and stiffness of red and white blood cells - sometimes over months. These results may help to explain why some affected people continue to complain of symptoms long after an infection (long Covid).
Mate choice is important for females, who often invest much more energy in offspring than males. However, being too selective is a bad idea, as they might end up not mating at all. Biologists have wondered for a long time how females optimize their chances. Scientists at the University of Groningen have performed experiments with fruit flies that reveal the explanation: mating induces a behavioural change in female flies that makes them more choosy than when they are virgins. The results were published on 21 June in Nature Ecology and Evolution.
University of Colorado Boulder researchers have discovered that minuscule, self-propelled particles called "nanoswimmers" can escape from mazes as much as 20 times faster than other, passive particles, paving the way for their use in everything from industrial clean-ups to medication delivery.
Basic needs of disaster- and conflict-impacted refugees are often met by humanitarian relief goods and services, and until now little was known about how refugees create economic livelihood beyond immediate relief.
PHILADELPHIA - The use of e-cigarettes, or vaping, causes serious damage to the lungs. After the novel coronavirus responsible for the respiratory disease COVID-19 emerged last year, there have been ongoing concerns about how vaping might impact risk of infection and severity of symptoms. Some evidence shows an increased risk of COVID-19 among those who vape. Research also shows a higher COVID-19 mortality rate in men compared to women, and men are more likely to vape than women. However, there is no evidence to link these two observations.
RICHLAND, Wash.--Researchers have increased the lifetime of a promising electric vehicle battery to a record level, an important step toward the goal of lighter, less expensive and long-lasting batteries for future electric vehicles. The work is reported June 28 in the journal Nature Energy.
Such batteries--the goal of research groups the world over--are seen as an important part of the solution to reduce the effects of climate change, and scientists are exploring a dizzying array of options.
(San Antonio, June 29, 2021) - UTSA criminology and criminal justice professors Michael R. Smith and Rob Tillyer working in collaboration with University of Cincinnati Professor Robin Engel examined racial and ethnic disparities in the use of force by the Fairfax County Police Department (FCPD). One of the nation's largest county police departments, the FCPD serves Fairfax County, Va., a major metropolitan county near Washington, D.C.
HOUSTON - (June 29, 2021) - When you think about trade and market relationships, you might think about brokers yelling at each other on the floor of a stock exchange on Wall Street. But it seems one of the basic functions of a free market is quietly practiced by fungi.
New research from a Rice University economist suggests certain networks of fungi embrace an important economic theory as they engage in trading nutrients for carbon with their host plants. This finding could aid the understanding of carbon storage in soils, an important tool in mitigating climate change.
