COVID-19 dual-antibody therapies effective against variants in animal study

Eurekalert - Jun 21 2021 - 00:06
A study from Washington University School of Medicine in St. Louis suggests that many, but not all, COVID-19 therapies made from combinations of two antibodies are effective against a wide range of virus variants. Further, combination therapies appear to prevent the emergence of drug resistance.

Potato nutrients can help reduce sodium retention, may help reduce risk of hypertension

Eurekalert - Jun 21 2021 - 00:06
New study investigates effect of increased dietary potassium from a whole food -- baked/boiled potatoes and baked French fries -- or a potassium supplement on blood pressure and other cardiovascular disease risk factors compared to a 'typical American' (lower potassium) diet. Results showed including baked/boiled potatoes as part of a typical American diet had the greatest benefit on sodium retention, even more than the supplement, and resulted in greater systolic blood pressure reduction than the control diet.

Vegetation of planet Earth: Researchers publish unique database as Open Access

Eurekalert - Jun 21 2021 - 00:06
It's a treasure trove of data: the global vegetation database 'sPlotOpen' is now freely accessible. It contains balanced, representative data on vegetation from 114 countries and from all climate zones on Earth. The database was compiled by an international team of researchers led by Martin Luther University Halle-Wittenberg (MLU), the German Centre for Integrative Biodiversity Research (iDiv) and the French National Centre for Scientific Research (CNRS).

Statin therapy not associated with cognitive decline, dementia in older adults, study says

Eurekalert - Jun 21 2021 - 00:06
The use of statin therapy in adults 65 years old or older is not associated with incident dementia, mild cognitive impairment (MCI) or decline in individual cognition domains, according to a study published in the Journal of the American College of Cardiology (JACC).

Study shows registry data could support clinical trials

Eurekalert - Jun 21 2021 - 00:06
Data captured in NCDR registries is similar in quality, depth and granularity when compared to data captured through clinical trials, according to research in JACC: Cardiovascular Interventions that compared data from the DAPT Study to NCDR CathPCI Registry data. This is good news for streamlining data collection and supports recent efforts to standardize data elements and definitions used in clinical trials and registries.

Childhood BMI may influence poorer health outcomes in adulthood

Eurekalert - Jun 21 2021 - 00:06
A high body mass index (BMI) during adolescence is a significant risk factor for Type 2 diabetes, early heart attack and overall poorer health for young adults, regardless of BMI in adulthood, according to a research letter published today in the Journal of the American College of Cardiology.

Researchers discover how the intestinal epithelium folds and moves by measuring forces

Eurekalert - Jun 21 2021 - 00:06
An international team led by Xavier Trepat at IBEC, with support from "La Caixa Foundation, measures the cellular forces in mini-intestines grown in the laboratory, deciphering how the inner wall of this vital organ folds and moves. The study, published in Nature Cell Biology, opens the doors to a better understanding of the bases of diseases such as celiac disease or cancer, and to the ability to find solutions for gut diseases through the development of new therapies.

New research unlocks the mystery of New England's beaches

Eurekalert - Jun 21 2021 - 00:06
Until now, the factors governing which beaches slope gradually to the sea and which ones end abruptly in a steep drop-off have been largely unknown. However, new research from the University of Massachusetts Amherst reveals, with unprecedented detail, how the grain size of beach sand relates to the slope of the beach itself. These new findings are critical to understanding how New England's beaches will respond to both rising sea levels and increased storm activity.

Physicists made photons be friends with magnons

Eurekalert - Jun 21 2021 - 00:06
A team of scientists from NUST MISIS and MIPT have developed and tested a new platform for realization of the ultra-strong photon-to-magnon coupling. The proposed system is on-chip and is based on thin-film hetero-structures with superconducting, ferromagnetic and insulating layers. This discovery solves a problem that has been on the agenda of research teams from different countries for the last 10 years, and opens new opportunities in implementing quantum technologies.

Third of Americans use gray market caregivers to aid the elderly and those with dementia

Eurekalert - Jun 21 2021 - 00:06
The rapid aging of the US population is expected to increase the demand for long-term care and supports to help with the activities of daily living. A new study finds that nearly a third of Americans who arranged for paid care for an older person or someone with dementia employed workers who were not hired through a regulated agency.

Antibody disease enhancement of COVID-19 does not appear to occur in animal models

Eurekalert - Jun 21 2021 - 00:06
In a study published in the journal Cell, Duke investigators demonstrated in mice and monkeys that human antibodies lacked the ability to make SARS-CoV-2 infection worse and, instead, exerted their defensive powers against the infection. The findings help reinforce evidence that antibodies are safe when given as treatments or induced by COVID-19 vaccines.

Gene profile in blood predicts risk of poor outcomes, death for patients with COVID-19

Eurekalert - Jun 21 2021 - 00:06
A blood gene profile associated with a high risk of dying from a severe lung disease can also predict poor outcomes in patients with COVID-19, a multicenter retrospective study led by the University of South Florida Health (USF Health) demonstrated. The risk profile based on 50 genes could help customize how COVID-19 is treated, improve allocation of limited health care resources such as intensive care beds and ventilators, and potentially save lives.
