Research team pairs 3-D bioprinting and computer modeling to examine cancer spread in blood vessels

Lawrence Livermore National Laboratory (LLNL) scientists have paired 3-D-printed, living human brain vasculature with advanced computational flow simulations to better understand tumor cell attachment to blood vessels, the first step in secondary tumor formation during cancer metastasis. The unique approach, developed with outside collaborators, lays the foundation for developing a predictive capability that can help

Many Americans struggling to afford health care in pandemic

More than two in five working-age U.S. adults didn’t have stable health insurance in the first half of 2020, while more than one-third struggled with medical bills, according to a new survey. “The survey shows a persistent vulnerability among U.S. working-age adults in their ability to afford coverage and health care. That vulnerability could worsen

A model for keeping the pandemic in check in Italy

A team of researchers has been modeling the potential spread of the coronavirus pandemic in Italy. Using their model, they can calculate the number of exposed and highly infectious individuals and the daily isolation efforts required to bring down the epidemic curve. In April, a team led by Professor Andrea Rinaldo, the head of EPFL’s

Has the coronavirus mutated in any significant way?

Has the coronavirus mutated in any significant way? It doesn’t seem to have changed in a way that makes people less or more sick. There’s some evidence that a specific mutation called D614G may have made it easier for the virus to be transmitted between people. But not all scientists are convinced, and it’s hard

US adds 1,300 virus deaths in 24 hours

Credit: CC0 Public Domain The US on Tuesday added 1,302 deaths from COVID-19 in the past 24 hours, according to a tally by Johns Hopkins University. The world’s largest economy also added 53,847 new cases of the virus, the Baltimore-based institution’s tracker showed at 8:30 pm (0030 GMT Wednesday). The US has now recorded 4,765,170

More COVID-19 patients in ICUs are surviving now: study

(HealthDay)—Even as new coronavirus infections soar in the United States, a new study offers one piece of good news: Severely ill COVID-19 patients are significantly more likely to survive now compared to a few months ago. In fact, deaths for COVID-19 patients in intensive care units have fallen by nearly a third in North America,

New PET radiotracer proven safe and effective in imaging malignant brain tumors

A first-in-human study presented at the Society of Nuclear Medicine and Molecular Imaging 2020 Annual Meeting has demonstrated the safety, favorable pharmacokinetic and dosimetry profile of 64Cu-EBRGD, a new, relatively long-lived PET tracer, in patients with glioblastomas. The radiotracer proved to be a superior, high-contrast imaging diagnostic in patients, visualizing tumors that express low or

Researchers identify possible immune targets in the SARS-CoV-2 genome

Otago researchers studying the COVID-19 virus (SARS-2) have discovered potential target points on its genome, which may contribute to future treatments for the virus. While their laboratory was locked down during the Level 4 period, Ph.D. student Ali Hosseini and Professor Alex McLellan from the Department of Microbiology and Immunology worked from their homes to

Genetic tests may differ in their interpretation of certain variants

(HealthDay)—Different genetic test interpretations have been identified for genetic variants, and some of these can impact patient management, according to a research letter published online June 30 in the Annals of Internal Medicine. Jeffrey A. SoRelle, M.D., from the University of Texas Southwestern Medical Center in Dallas, and colleagues examined the prevalence of different interpretations
