Queensland University of Technology (QUT) researchers have created a new molecular coupling tool employing both green light and pH triggers that has potential for use in applications such as drug delivery and 3D cell culture platforms.
Their research has been published in the journal Nature Communications.
Several new papers in Journal of Antimicrobial Chemotherapy, published by Oxford University Press, suggest successful treatments for COVID-19.
Three articles all researched the use of sofosbuvir and daclatasvir for the treatment of COVID-19. These three papers come from Iran, which has developed its own pill containing sofosbuvir and daclatasvir, and is in a position to test this in a large clinical trial as Iran is a massively impacted country, reporting some 2500 cases and 200 deaths a day.
fibrillation manage their symptoms, according to research presented today at ESC Congress 2020.1
Atrial fibrillation is the most common heart rhythm disorder. One in four middle-aged adults in Europe and the US will develop the condition, which causes 20-30% of all strokes and increases the risk of death by 1.5-fold in men and 2-fold in women. Reduced quality of life is common, and 10-40% of patients are hospitalised each year.2
Symptoms of atrial fibrillation include palpitations, racing or irregular pulse, shortness of breath, tiredness, chest pain and dizziness.
WASHINGTON -- Voters who express prejudice against minorities and women are still more likely to support candidates who most closely align with their ideologies, regardless of the race or sex of such candidates, according to research published by the American Psychological Association.
DALLAS - Aug. 20, 2020 - A pregnant mother who tested positive for COVID-19 transmitted the virus causing the disease to her prematurely born baby, UT Southwestern physicians report. Both were treated and recovered.
Six black-naped terns -- a coastal seabird found in the Pacific and Indian Oceans -- have given researchers a glimpse into how they navigate tropical typhoons.
The research team based in Japan published their analysis on May 30 in Marine Biology, a Springer journal.
"Our goal was to examine the migration characteristics of the black-naped terns from the Okinawa Islands," said paper author Jean-Baptiste Thiebot, project researcher at the National Institute of Polar Research (NIPR) in Japan. "The bird is listed as vulnerable by Japan's Ministry of Environment."
Researchers from the University's National Marine Science Centre have demonstrated that imidacloprid, a neonicotinoid insecticide, can impact the feeding behaviour of prawns in a laboratory environment, leading to nutritional deficiency and reduced flesh quality.
"The sobering thing with this study is that it shows that the exposure of prawns to high concentrations of neonicotinoids can have such a significant impact," said lead author and PhD candidate Peter Butcherine whose study focussed on adult black tiger prawns.
BEER-SHEVA, Israel...August 24, 2020 - Wastewater containing coronaviruses may be a serious threat, according to a new, global study led by researchers from the Zuckerberg Institute for Water Research at Ben-Gurion University of the Negev (BGU).
The origins of birds and their flight was a major event in the history of life. A wealth of spectacular fossils has demonstrated that birds are theropod dinosaurs, with Pennaraptora being the most relevant subgroup to transition from non-avian dinosaurs to birds. Here we announce the publication of a landmark journal volume on pennaraptoran theropods (Figure 1) edited by HKU Research Assistant Professor Dr. Michael Pittman (Vertebrate Palaeontology Laboratory, Division of Earth and Planetary Science & Department of Earth Sciences) and Prof.
A research team led by neurobiologist Professor Claire Jacob has identified an important mechanism that can be used to control the restoration of myelin sheaths following traumatic injury and in degenerative diseases. With the insights gained, the researchers were able to regenerate damaged myelin sheaths in mice by treating them with the active substance theophylline, thereby restoring their nerve cell function. The groundbreaking findings are the result of research carried out at Johannes Gutenberg University Mainz (JGU) and the University of Fribourg in Switzerland.
University of Sussex quantum physicists have developed an algorithm which helps early quantum computers to perform calculations most efficiently
The team used their model to calculate the expected computational power of early quantum computers
Their research highlights a fundamental advantage of the 'trapped ion' approach over other methods
New research by the University of Minnesota and the University of Washington finds that every six additional ICU beds or seven additional non-ICU beds filled by COVID-19 patients leads to one additional COVID-19 death over the following week.
"A spike in hospitalization naturally leads to more deaths, but these deaths may not only come from those who are hospitalized, but also from those who should have been hospitalized but were not," said co-author Anirban Basu, a UW professor of health economics.
The human microbiota plays an important role in health and well-being by assisting in digestion, producing nutrients, resisting invading pathogens and regulating metabolism and the immune system.
We use antimicrobial (AM) drugs to treat common infections even though they have an immediate effect on microbial diversity and composition.
Most of the studies have earlier focused on faecal (gut) microbiota, but microbes in other niches of the body have also showed importance for human health and well-being.
When algae and bacteria with different swimming gaits gather in large groups, their flocking behaviour diminishes, something that may reduce the risk of falling victim to aquatic predators. This finding is presented in an international study led from Lund University in Sweden.
A team of researchers at the Max Planck Institute for Chemical Ecology in Jena, Germany, has discovered that strigolactones, a class of novel plant hormones, mediate the fine-tuning of the production plant defensive substances in the stem of plants of the wild tobacco species Nicotiana attenuata. In a cooperative project with partners in China and Korea, they found that strigolactones and their crosstalk with other hormones involved in plant defense were crucial for tobacco plants' ability to tolerate insects that live inside the stem.
