For our cells to assemble into tissues and whole organs, the extracellular ma-trix (ECM) as well as the integrins are required. The ECM forms a kind of extra-cellular protein meshwork, the integrins are surface proteins, which our cells use to attach to this extracellular support structure. How human cells balance attachment to versus detachment from the ECM is a yet unsolved question. The research team led by Professor Christof Hauck in the Department of Biolo-gy at the University of Konstanz, now identified a key enzyme, PPM1F, which regulates the integrins' detachment from the ECM.
ITHACA, N.Y. - In emerging renewable energy industries, are producers' decisions to shut down or upgrade aging equipment influenced more by technology improvements or government policies?
It's an important long-term question for policymakers seeking to increase renewable electricity production, cost-effectiveness and efficiency with limited budgets, says C.-Y. Cynthia Lin Lawell, associate professor in the Charles H. Dyson School of Applied Economics and Management at Cornell University.
TAMPA, Fla (Nov. 6, 2020) -- SARS-CoV-2, the respiratory virus that causes COVID-19, attacks the body in multiple steps. Gaining entry into cells deep within the lungs and hijacking the human host cell's machinery to churn out copies of itself are two of the earliest steps -- both essential for viral infection.
JUPITER, FL--A new strategy for treating a variety of diseases known as RNA-repeat expansion disorders, which affect millions of people, has shown promise in proof-of-principle tests conducted by scientists at Scripps Research.
The results suggest that someday, a handful of well-targeted drugs might be able to treat the more than 40 human disorders--including Huntington's disease and variants of amyotrophic lateral sclerosis (ALS)--that arise from RNA-repeat expansions.
High deductible health plans (HDHPs) have become much more common among all racial/ethnic and income groups, but the health savings accounts (HSAs) that make these plans potentially workable are far less common among Black, Hispanic, and lower-income enrollees--and the gap is growing.
That's according to a new Boston University School of Public Health (BUSPH) study published in the November issue of the journal Health Affairs, the first to examine these trends.
A new Boston University School of Public Health study of the first four months of America's coronavirus epidemic, published in the journal Nature Human Behaviour, shows that physical distancing (also called "social distancing") policies had little effect on lower income people still needing to leave their homes to go to work--but does show them staying home when they could.
MIAMI--A new study by researchers at the University of Miami (UM) Rosenstiel School of Marine and Atmospheric Science projects an increase in Florida's late summertime rainfall with rising Atlantic Ocean temperatures.
AMHERST, Mass. - In a new paper with results that senior author Eric Strieter at the University of Massachusetts Amherst calls "incredibly surprising," he and his chemistry lab group report that they have discovered how an enzyme known as UCH37 regulates a cell's waste management system.
Strieter says, "It took us eight years to figure it out, and I'm very proud of this work. We had to develop a lot of new methods and tools to understand what this enzyme is doing."
A researcher from University of Southern California published a new paper in the Journal of Marketing that explores whether attractive food might seem healthier to consumers. The study forthcoming in the Journal of Marketing is titled "Pretty Healthy Food: How and When Aesthetics Enhance Perceived Healthiness" and is authored by Linda Hagen.
A new study led by Maria Manuel Mota, group leader at Instituto de Medicina Molecular João Lobo Antunes (iMM; Portugal), now shows that malaria parasites secrete the protein EXP2 that is required for their entry into hepatocytes. These findings, published today in the scientific journal Nature Communications*, open a new avenue for prophylactic anti-malarial strategies, since blocking or decreasing the infection of the liver can prevent the disease.
A genetically edited form of a herpes simplex virus -- rewired to keep it from taking refuge in the nervous system and eluding an immune response -- has outperformed a leading vaccine candidate in a new study from the University of Cincinnati, Northwestern University and the University of Nebraska-Lincoln.
A small team of astronomers have found a new way to 'see' the elusive dark matter haloes that surround galaxies, with a new technique 10 times more precise than the previous-best method. The work is published in Monthly Notices of the Royal Astronomical Society.
Scientists currently estimate that up to 85% of the mass in the universe is effectively invisible. This 'dark matter' cannot be observed directly, because it does not interact with light in the same way as the ordinary matter that makes up stars, planets, and life on Earth.
ATLANTA -- New research shows that corticosteroid injections for knee OA treatment do not hasten a patient's progression to a total knee replacement when compared with hyaluronic acid injections. Details of this study was presented at ACR Convergence, the American College of Rheumatology's annual meeting (ABSTRACT #1652).
ATLANTA -- New research presented at ACR Convergence, the American College Rheumatology's annual meeting, reveals that romosozumab, an osteoporosis drug, produces substantial gains in bone mineral density in the hip and lumbar spine within one year, and that transitioning patients to a potent antiresorptive drug can lead to even more bone density gains (ABSTRACT #1973).
ATLANTA -- New research shows that children with Kawasaki Disease remain at an increased risk for cardiovascular events more than 10 years after hospitalization for their condition, highlighting the need for long-term heart disease surveillance and risk reduction strategies for these young patients.
