Scientists from the Institute of Physical Chemistry of the Polish Academy of Sciences (IPC PAS) in cooperation with the Faculty of Chemistry of the Warsaw University of Technology (WUT) have developed a new, solvent-free method for the encapsulation of drug molecules in MOF (Metal-Organic Framework) porous materials.
In satellite photos of the Earth, clouds of bright green bloom across the surface of lakes and oceans as algae populations explode in nutrient-rich water. From the air, the algae appear to be the primary players in the ecological drama unfolding below.
But those single-celled organisms we credit for influencing the aquatic environment at the base of the food chain may be under the influence of something else: viruses whose genes can reconfigure their hosts' metabolism.
Biofuels are an important part of the broader strategy to replace petroleum-based gasoline, diesel, and jet fuels that we use today. However, biofuels have so far not reached cost parity with conventional petroleum fuels.
People with aortic stenosis and a low surgical risk became eligible for a less invasive valve replacement last summer, spurring increased demand for the catheter-based procedure called TAVR. But only a subset of U.S. hospitals, including Michigan Medicine's Frankel Cardiovascular Center, are able to offer transcatheter aortic valve replacement.
New Medicare rules have lowered procedural volume requirements for hospitals who wish to offer TAVR to their patients.
But will this truly allow more people to get a TAVR who had trouble accessing the procedure before?
Researchers have shown how a by-product of steel making can be used to both treat wastewater and make stronger concrete, in a zero-waste approach to help advance the circular economy.
Produced during the separation of molten steel from impurities, steel slag is often used as a substitute aggregate material for making concrete.
Steel slag can also be used to absorb contaminants like phosphate, magnesium, iron, calcium, silica and aluminium in the wastewater treatment process, but loses its effectiveness over time.
The lungs are constantly exposed to the external environment and maintain homeostasis by adapting to stress and tissue damage. Furthermore, lung function is known to decrease with age so respiratory failure can occur if their structure or function breaks down. It is therefore important for aging societies around the world to search for factors inside and outside the body that directly affect lung function.
The world has been hit hard by coronavirus, and health services and authorities everywhere are struggling to reduce the spread, combat the disease and protect the population. Nevertheless, the pandemic will cost lives throughout the world. An environmental researcher from Aarhus University has studied whether there could be a link between the high mortality rate seen in northern Italy, and the level of air pollution in the same region. The short answer is "yes possibly". The long answer is in the article below.
Study from University of Warwick reveals dynamics of the protein assemblies that make up cellular 'muscles'
The dumbbell-shaped protein myosin II is similar to the one in our own muscles
New microscopy technique applied to visualise label free ensembles of myosin for first time
Self-organising ensembles could provide a model for future smart materials
The movements of cell muscles in the form of tiny filaments of proteins have been visualised at unprecedented detail by University of Warwick scientists.
Atomic bomb tests conducted during the Cold War have helped scientists for the first time correctly determine the age of whale sharks.
The discovery, published in the journal Frontiers in Marine Science, will help ensure the survival of the species - the largest fish in the world - which is classified as endangered.
Measuring the age of whale sharks (Rhincodon typus) has been difficult because, like all sharks and rays, they lack bony structures called otoliths that are used to assess the age of other fish.
Ann Arbor, April 6, 2020 - A new study in the American Journal of Preventive Medicine, published by Elsevier, reports valuable new grip strength metrics that provide healthcare practitioners with an easy-to-perform, time-efficient screening tool for type 2 diabetes (T2DM).
The ice giant Uranus' unusual attributes have long puzzled scientists. All of the planets in our Solar System revolve around the Sun in the same direction and in the same plane, which astronomers believe is a vestige of how our Solar System formed from a spinning disc of gas and dust. Most of the planets in our Solar System also rotate in the same direction, with their poles orientated perpendicular to the plane the planets revolve in. However, uniquely among all the planets, Uranus' is tilted over about 98 degrees.
New research led by hearing scientists at Oregon Health & Science University suggests an avenue to treat and prevent intractable genetic disorders before birth.
Researchers at the Oregon Hearing Research Center, working with mice, injected a specially designed synthetic molecule into the developing inner ear of fetal mice 12 days after fertilization. The study found that the technique corrected the expression of a mutated gene that causes Usher syndrome, a disorder characterized by deafness and progressive vision loss affecting an estimated 4 to 17 of every 100,000 people.
As a Yale University postdoctoral researcher, economist Jude Bayham studied the potential consequences of a global pandemic that could shutter schools, close businesses, and strain hospitals. That was back in 2013.
Now, as the world grapples with the coronavirus, the Colorado State University economist and a multi-institutional team are turning those prescient modeling exercises into real insights for policymakers.
US policymakers considering physical distancing measures to slow the spread of COVID-19 face a difficult trade-off between closing schools to reduce transmission and new cases, and potential health-care worker absenteeism due to additional childcare needs that could ultimately increase mortality from COVID-19, according to new modelling research published in The Lancet Public Health journal.
A sponge found in Manado Bay, Indonesia, makes a molecule called manzamine A, which stops the growth of cervical cancer cells, according to a recent publication in the Journal of Natural Products submitted by researchers at the Medical University of South Carolina (MUSC) and their collaborators. Collaborators include students and investigators at the University of South Carolina (UofSC), College of Charleston, Gadjah Mada University in Indonesia and the University of Malaya in Malaysia.
