For eradication of HIV-1 infection, it is important to elucidate the detailed features and heterogeneity of HIV-1-infected cells in vivo. In this study, a hematopoietic stem cell-transplanted humanized mouse model infected with a gene-modified HIV-1 was used to reveal multiple characteristics of HIV-1-producing cells in vivo.
A research group at The Institute of Medical Science, The University of Tokyo (IMSUT) using HIV-1-infected cells performed "multiomics" analyses, which are technologies recently developed to comprehensively investigate the features of biological samples.
A protein produced by the human immune system can strongly inhibit corona viruses, including Sars-Cov-2, the pathogen causing Covid-19. An international team from Germany, Switzerland and the USA successfully showed that the LY6E-Protein prevents coronaviruses from causing an infection.
UNIVERSITY PARK, Pa. -- By reconstructing the evolutionary history of SARS-CoV-2, the virus that is responsible for the COVID-19 pandemic, an international research team of Chinese, European and U.S. scientists has discovered that the lineage that gave rise to the virus has been circulating in bats for decades and likely includes other viruses with the ability to infect humans. The findings have implications for the prevention of future pandemics stemming from this lineage.
While there is little doubt that COVID-19 will have lasting impacts on health and the economy, a group of researchers is bringing attention to the effects the pandemic could have on the careers of scientific researchers. Carnegie Mellon University and Max Planck Institute physicist Ulrike Endesfelder, University of Stuttgart's Dirk Pflüger and Technische Universität Braunschweig's Timo de Wolff launched a Twitter campaign #StopPandemicBias, which aims to bring broader understanding to how COVID-19 will impact scientists.
An extensive international study led by Prof. Illana Gozes of Tel Aviv University's Department of Human Molecular Genetics and Biochemistry found deposits of the tau protein typically found in Alzheimer's patients in tissues taken from the postmortem brain of a 7-year-old autistic child.
Philadelphia, July 28, 2020 - Imagine a young girl with a peanut allergy, so stricken by fear of anaphylaxis that she no longer takes part in everyday activities many children take for granted. She's stopped playing with her siblings, worried that residue from their peanut butter crackers may trigger an allergic reaction. She obsessively washes her hands to make sure there is no trace of peanut on them. She worries that every stomachache could mean she accidently ate something she was allergic to.
According to new research, the failure to protect tropical rain forests has cost trillions of dollars stemming from the coronavirus pandemic, which has wreaked economic havoc and caused historic levels of unemployment in the United States and around the world.
AMES, Iowa - Exposure to the chemical glyphosate changed the level of some ovarian proteins in mice but did not impact ovarian steroid production, an indication glyphosate may not adversely affect reproduction, according to a new study.
Fossil remains of a novel species of lizard that lived more than 130 million years ago have been found in the north of Minas Gerais, Brazil. It has been named Neokotus sanfranciscanus and is the oldest representative of the order Squamata ever found in South America.
Squamates are the largest reptile group, comprising lizards, snakes and amphisbaenians (worm lizards).
Philadelphia, July 27, 2020--As the COVID-19 pandemic took hold, hospitals across the country cancelled elective procedures in an effort to flatten the transmission curve and prioritize personal protective equipment for frontline health care workers. Among those procedures were pediatric spine surgeries for patients with conditions like scoliosis and thoracic insufficiency syndrome.
BROOKLYN, New York, Monday, July 27, 2020 - Fascinating opportunities are emerging from a new class of materials named two-dimensional (2D) semiconductors, which are only one atom thick. 2D materials are poised to have a bright future in the electronics and optoelectronics industry, as well as in Internet of Things devices. Any cell phone, computer, electronic device, and even solar cells, are all composed of the same basic electronic building block, the diode.
TROY, N.Y. -- When the Shewanella oneidensis bacterium "breathes" in certain metal and sulfur compounds anaerobically, the way an aerobic organism would process oxygen, it produces materials that could be used to enhance electronics, electrochemical energy storage, and drug-delivery devices.
The ability of this bacterium to produce molybdenum disulfide -- a material that is able to transfer electrons easily, like graphene -- is the focus of research published in Biointerphases by a team of engineers from Rensselaer Polytechnic Institute.
The majority of U.S. gun owners support measures such as background checks, but report not vocally supporting these policies because they feel disrespected by health advocates.
A new Boston University School of Public Health (BUSPH) study sheds new light on the opinions and practices of U.S. gun owners, casting doubt on the way gun owners have been portrayed in policy discussions and media, and even how they perceive themselves.
Analyses of lung fluid cells from COVID-19 patients conducted on the nation's fastest supercomputer point to gene expression patterns that may explain the runaway symptoms produced by the body's response to SARS-CoV-2.
A team led by Dan Jacobson of the Department of Energy's Oak Ridge National Laboratory used the Summit supercomputer at ORNL to analyze genes from cells in the lung fluid of nine COVID-19 patients compared with 40 control patients.
WASHINGTON, D.C.--The signs of physical abuse among elderly people can be challenging for health care professionals to recognize, resulting in as few as one in 24 cases being reported to authorities. However, a new study in Annals of Emergency Medicine explores injury patterns and characteristics to help experts spot key differences between abuse and unintentional injury.
