(Toronto - May 15, 2020) - An international team of researchers led by Dr. Eleanor Fish, emerita scientist at the Toronto General Hospital Research Institute, University Health Network, and professor in the University of Toronto's Department of Immunology, has shown for the first time that an antiviral drug can help speed up the recovery of COVID-19 patients.
High salt intake is a well-known risk factor of hypertension and cardiovascular diseases. Reducing salt intake can significantly lower blood pressure and ameliorate target organ damage caused by hypertension. However, in the past three decades, several strategies have failed to decrease daily salt intake to an optimal level. Therefore, it is important to identify alternative approaches for reducing excessive salt intake and antagonizing high salt-induced hypertension.
According to a new study published in De Gruyter's open access journal "Diagnosis", approximately one in 10 people (9.6%) in the United States with symptoms caused by major vascular events, infections, or cancers will be misdiagnosed.
The study's authors, led by David E. Newman-Toker from the Johns Hopkins University School of Medicine and CRICO Strategies, analyzed modern, U.S.-based studies and literature-based estimates to calculate rates of diagnostic error and related harms.
Lung cancer patients are at heightened risk for COVID-19 and the reported high mortality rate among lung cancer patients with COVID-19 has given pause to oncologists who are faced with patients with not one, but two severe, life-threatening diseases.
MANHATTAN, KANSAS -- An interdisciplinary team of Kansas State University researchers developed a computer simulation that revealed beef supply chain vulnerabilities that need safeguarding -- a realistic concern during the COVID-19 pandemic.
Caterina Scoglio, professor, and Qihui Yang, doctoral student, both in electrical and computer engineering, recently published "Developing an agent-based model to simulate the beef cattle production and transportation in southwest Kansas" in Physica A, an Elsevier journal publication.
The results of a study conducted by the University of Tartu on the prevalence of the coronavirus were presented to the Government Committee responsible for the emergency situation on Tuesday. The results from the second week of the study continue to confirm the low prevalence of the virus in Estonia.
A parent who knows a child's preferences and participates in the activities can guide the child assertively without diminishing the child's enthusiasm for physical activity and exercise. However, children's enthusiasm to move was most commonly associated with child-centered and stimulating parenting. In an interview study conducted at the Faculty of Sport and Health Sciences of the University of Jyväskylä, children perceived coercion as reducing their motivation for physical activity.
Although they do it differently than humans, plants also have memories. For example, many plants can sense and remember prolonged cold in the Winter to ensure they flower at the right time during the Spring. This so-called "epigenetic memory" occurs by modifying specialized proteins called histones, which are important for packaging and indexing DNA in the cell. One such histone modification, called H3K27me3, tends to mark genes that are turned off. In the case of flowering, cold conditions cause H3K27me3 to accumulate at genes that control flowering.
Scientists have discovered a new treatment to dramatically reduce swelling after brain and spinal cord injuries, offering hope to 75 million victims worldwide each year.
The breakthrough in treating such injuries - referred to as central nervous system (CNS) edema - is thought to be hugely significant because current options are limited to putting patients in an induced coma or performing risky surgery.
What The Viewpoint Says: Publicly available data were used to analyze the number of deaths from seasonal influenza deaths compared with deaths from COVID-19.

New research from the University of Sheffield into stem cells could help make regenerative medicine safer
Regenerative medicine involves using pluripotent stem cells to repair damaged or diseased tissues in the body
The new research has suggested ways to reduce the likelihood of mutations occurring in these cells when cultured.
Research from the University of Sheffield has given new insight into the cause of mutations in pluripotent stem cells and potential ways of stopping these mutations from occurring.
Since 2013, following strict enforcement of provincial wildlife legislation in the less studied regions of Asia, the overall trend of illegal reptile poaching is steadily decreasing. But it's too early to claim that the issue is solved.
Astronomers using the Subaru Telescope have determined that the Earth-like planets of the TRAPPIST-1 system are not significantly misaligned with the rotation of the star. This is an important result for understanding the evolution of planetary systems around very low-mass stars in general, and in particular the history of the TRAPPIST-1 planets including the ones near the habitable zone.
Today Boa snakes have a patchy distribution in the islands that form the Lesser Antilles in the Caribbean Sea, but the constrictors are nearly absent from archaeological deposits in the region. Whether this scarcity is due to past species distribution, poor preservation conditions, or a lack of interaction with human communities, remains unknown.
