The most complete picture yet is coming into focus of how antibodies produced in people who effectively fight off SARS-CoV-2 work to neutralize the part of the virus responsible for causing infection. In the journal Science, researchers at The University of Texas at Austin describe the finding, which represents good news for designing the next generation of vaccines to protect against variants of the virus or future emerging coronaviruses.
BAR HARBOR, MAINE — Our kidneys are charged with the extraordinary task of filtering about 53 gallons of fluid a day, a process that depends on podocytes, tiny, highly specialized cells in the cluster of blood vessels in the kidney where waste is filtered that are highly vulnerable to damage.
Biological organisms (such as elephant trunks, octopus tentacles, and human tongues) show remarkable dexterity and self-adaptation in unstructured environments, relying on the multiple-mode actuations of the skeleton-free muscular hydrostats. In general, muscular hydrostats mainly consist of well-ranged active 3D muscle-fiber arrays bundled by passive connective tissues (Fig. 1A). By selectively actuating the active 3D muscle-fiber arrays, muscular hydrostats can generate elongation, bending, contraction and twisting.
A Pediatric Policy Council state of the art plenary session during the Pediatric Academic Societies (PAS) 2021 Virtual Meeting explored the role of public health research in iterative policymaking to reduce gun violence in America.
Researchers at University of California San Diego School of Medicine, with colleagues elsewhere, have used gene therapy to prevent learning and memory loss in a mouse model of Alzheimer's disease (AD), a key step toward eventually testing the approach in humans with the neurodegenerative disease.
The findings are published online in advance of the June 11, 2021 issue of Molecular Therapy-Methods & Clinical Development.
During the next 10 years, an estimated half-million individuals in the U.S. with autism spectrum disorder (ASD) are expected to transition from adolescence to adulthood, according to the Centers for Disease Control and Prevention.
That means thousands of these young adults will likely fall into a widening and potentially devastating gap in a variety of services--because they're too old for high school, but may not qualify for Medicaid-funded services, social work researchers at Case Western Reserve University predict in a new study.
ORLANDO, Fla. (May 3, 2021) - Researchers have identified a gene expressed in children with acute myeloid leukemia (AML) that could serve as a new immunotherapy treatment target, according to a new study published today in Blood Advances, a journal of the American Society of Hematology. The study, co-authored by researchers with Nemours Children's Health System, outlines the process and potential path for new immunotherapy drugs that improve survival and reduce treatment-related toxicity in children with AML.
Coronavirus (CoVs) infection in animals and humans is not new. The earliest papers in the scientific literature of coronavirus infection date to 1966. However, prior to SARS-CoV, MERS-CoV, and SARS-CoV-2, very little attention had been paid to coronaviruses.
Many miles of streams and rivers in the United States and elsewhere are polluted by toxic metals in acidic runoff draining from abandoned mining sites, and major investments have been made to clean up acid mine drainage at some sites. A new study based on long-term monitoring data from four sites in the western United States shows that cleanup efforts can allow affected streams to recover to near natural conditions within 10 to 15 years after the start of abatement work.
BOSTON -- Immunity often calls to mind the adaptive immune response, made up of antibodies and T cells that learn to fight specific pathogens after infection or vaccination. But the immune system also has an innate immune response, which uses a set number of techniques to provide a swift, non-specialized response against pathogens or support the adaptive immune response.
MINNEAPOLIS - Chronic kidney disease is when a person's kidneys progressively lose their ability to filter waste from the blood and eliminate fluids. Now a new study has found that people with reduced kidney function may have an increased risk of developing dementia. The study is published in the May 5, 2021, online issue of Neurology®, the medical journal of the American Academy of Neurology.
Virtual care provided through telephone or videoconference has been broadly implemented in recent months because of the COVID-19 pandemic. A new analysis of published studies has examined the accuracy and reliability of virtual compared with in-person cognitive assessments for diagnosing dementia or mild cognitive impairment.
A new study published in the British Journal of Educational Technology has identified the different needs of students across primary, middle, and high school related to online learning during the COVID-19 pandemic.
For the study, investigators surveyed 1,170,769 Chinese students from the Guangdong Province of China.
The population growth of an endangered butterfly species is greatest in habitats with microclimatic variability, demonstrates a study carried out collaboratively by the Faculty of Biological and Environmental Sciences and the Helsinki Institute of Life Science of the University of Helsinki as well as the Finnish Environment Institute.
