Genetically engineered nanoparticle delivers dexamethasone directly to inflamed lungs

Genetically engineered nanoparticle delivers dexamethasone directly to inflamed lungs
2021-06-16
(Press-News.org) Nanoengineers at the University of California San Diego have developed immune cell-mimicking nanoparticles that target inflammation in the lungs and deliver drugs directly where they're needed. As a proof of concept, the researchers filled the nanoparticles with the drug dexamethasone and administered them to mice with inflamed lung tissue. Inflammation was completely treated in mice given the nanoparticles, at a drug concentration where standard delivery methods did not have any efficacy.

The researchers reported their findings in Science Advances on June 16.

What's special about these nanoparticles is that they are coated in a cell membrane that's been genetically engineered to look for and bind to inflamed lung cells. They are the latest in the line of END

Study: A quarter of adults dont want children -- and theyre still happy
2021-06-16
Parenting is one of life's greatest joys, right? Not for everyone. New research from Michigan State University psychologists examines characteristics and satisfaction of adults who don't want children. As more people acknowledge they simply don't want to have kids, Jennifer Watling Neal and Zachary Neal, both associate professors in MSU's department of psychology, are among the first to dive deeper into how these "child-free" individuals differ from others. "Most studies haven't asked the questions necessary to distinguish 'child-free' individuals -- those who choose not to have children -- from other types of nonparents," Jennifer Watling Neal said. ...

How do immune cells get activated?

How do immune cells get activated?
2021-06-16
Chemokine receptors, located at the surface of many immune cells, play an important role in their function. Chemokines are small proteins that bind to these receptors and control the movement and behaviour of white blood cells. However, despite the importance of this family of receptors, their activation mechanism remains poorly understood. In Switzerland, a research consortium from the University of Geneva (UNIGE), the Biozentrum of the University of Basel, and the Paul Scherrer Institute (PSI) in Villigen has succeeded in decoding the activation mechanism of the CCR5 receptor, a member of this family implicated in several diseases such as HIV/AIDS, cancer, and the respiratory ...

Intermittent fasting 'no magic bullet for weight loss' says new study

2021-06-16
New research published this week challenges a popular belief that intermittent fasting diets such as alternate day fasting or the '5:2' are the most effective ways to lose weight. Over recent years, diets which see people fast on a few days each week have increased in popularity, reinforced by images of people's miraculous weight transformations, and backed by celebrity endorsements. However, evidence to date about the effectiveness of fasting compared with more traditional diets which aim to reduce calorie intake over the course of a full week has been limited. Published in the prestigious journal Science Translational Medicine, the new study from a team of physiologists at the University of Bath builds this evidence and indicates that there is 'nothing ...

Advocating reimbursement parity for nurse practitioners

Advocating reimbursement parity for nurse practitioners
2021-06-16
PHILADELPHIA (June 16, 2021) - The current Medicare reimbursement policy for nurse practitioners (NPs) allows NPs to directly bill Medicare for services that they perform, but they are reimbursed at only 85% of the physician rate. A growing number of states are granting full practice authority to nurse practitioners. Even more states have loosened practice restrictions due to COVID-19. Both of these reasons illustrate why payment parity is essential. In an article in The Online Journal of Issues in Nursing, Alycia Bischof, MSN, APRN, PNP-BC, Senior Lecturer at the ...

The give and take of mega-flares from stars
2021-06-16
The long relationships between stars and the planets around them - including the Sun and the Earth - may be even more complex than previously thought. This is one conclusion of a new study involving thousands of stars using NASA's Chandra X-ray Observatory. By conducting the largest survey ever of star-forming regions in X-rays, a team of researchers has helped outline the link between very powerful flares, or outbursts, from youthful stars, and the impact they could have on planets in orbit. "Our work tells us how the Sun may have behaved and affected ...

Researchers uncover unique properties of a promising new superconductor

Researchers uncover unique properties of a promising new superconductor
2021-06-16
An international team of physicists led by the University of Minnesota has discovered that a unique superconducting metal is more resilient when used as a very thin layer. The research is the first step toward a larger goal of understanding unconventional superconducting states in materials, which could possibly be used in quantum computing in the future. The collaboration includes four faculty members in the University of Minnesota's School of Physics and Astronomy--Associate Professor Vlad Pribiag, Professor Rafael Fernandes, and Assistant Professors Fiona Burnell and Ke Wang--along with physicists ...

How a supermassive black hole originates

How a supermassive black hole originates
2021-06-16
RIVERSIDE, Calif. -- Supermassive black holes, or SMBHs, are black holes with masses that are several million to billion times the mass of our sun. The Milky Way hosts an SMBH with mass a few million times the solar mass. Surprisingly, astrophysical observations show that SMBHs already existed when the universe was very young. For example, a billion solar mass black holes are found when the universe was just 6% of its current age, 13.7 billion years. How do these SMBHs in the early universe originate? A team led by a theoretical physicist at the University of California, Riverside, has come up with an explanation: a massive seed black hole that the collapse of a dark matter halo could produce. Dark matter halo is the halo of invisible matter ...

Pioneering chemistry approach could lead to more robust soft electronics

Pioneering chemistry approach could lead to more robust soft electronics
2021-06-16
RESEARCH TRIANGLE PARK, N.C. -- A new approach to studying conjugated polymers made it possible for an Army-funded research team to measure, for the first time, the individual molecules' mechanical and kinetic properties during polymerization reaction. The insights gained could lead to more flexible and robust soft electronic materials, such as health monitors and soft robotics. Conjugated polymers are essentially clusters of molecules strung along a backbone that can conduct electrons and absorb light. This makes them a perfect fit for creating soft optoelectronics, such as wearable electronic devices; however, as flexible as they are, these polymers are difficult to study in bulk because they aggregate ...

P-glycoprotein removes Alzheimer's-associated toxin from the brain

P-glycoprotein removes Alzheimers-associated toxin from the brain
2021-06-16
DALLAS (SMU) -- A team of SMU biological scientists has confirmed that P-glycoprotein (P-gp) has the ability to remove a toxin from the brain that is associated with Alzheimer's disease. The finding could lead to new treatments for the disease that affects nearly 6 million Americans. It was that hope that motivated lead researchers James W. McCormick and Lauren Ammerman to pursue the research as SMU graduate students after they both lost a grandmother to the disease while at SMU. In the Alzheimer's brain, abnormal levels of amyloid-β proteins clump together to form plaques that collect between neurons and can disrupt cell function. ...
