Clinical trial suggests convalescent plasma may improve survival with severe ...
17 May 2021 at 9:50am
A randomized double-blind controlled trial of convalescent plasma for adults hospitalized with severe COVID-19 found that mortality at 28 days in the treatment arm was half the rate seen in the control arm (12.6 percent vs. 24.6 percent), although treatment was not associated with other improvements in clinical status.
Alcohol may have immediate effect on atrial fibrillation risk, events
17 May 2021 at 9:49am
Alcohol appears to have an immediate -- or near-immediate -- effect on heart rhythm, significantly increasing the chance that an episode of atrial fibrillation (AFib) will occur, according to new research.
Rare COVID-19 response in children explained
17 May 2021 at 9:47am
One of the enduring mysteries of the COVID-19 pandemic is why most children tend to experience fewer symptoms than adults after infection with the coronavirus. The immune system response that occurs in the rare cases in which children experience life-threatening reactions after infection may offer an important insight, a new study suggests.
Scientists find new way of predicting COVID-19 vaccine efficacy
17 May 2021 at 7:57am
Australian researchers have identified the immune response associated with protection from COVID-19 -- a discovery that may help cut the time it takes to develop new vaccines.
Sperm help 'persuade' the female to accept pregnancy
17 May 2021 at 7:26am
Sperm are generally viewed as having just one action in reproduction -- to fertilize the female's egg - but studies are overturning that view.
High-intensity intermittent training improves spatial memory in rats
17 May 2021 at 7:26am
Despite lower exercise volume, HIIT was as effective as endurance running for improving exercise capacity and spatial memory. Researchers found that activity-specific physiological adaptations in the muscles and increased signaling and neurogenesis in the hippocampus underlie these improvements. Findings also suggested that benefits can potentially be optimized by tailoring exercise time and intensity.
Engineered organism could diagnose Crohn's disease flareups
17 May 2021 at 7:26am
Researchers have engineered a bacterium capable of diagnosing a human disease, a milestone in the field of synthetic biology.
New epigenetic regulatory mechanisms involved in multiple myeloma growth
17 May 2021 at 7:26am
An international team of researchers has analyzed the function of the histone demethylase KDM5A in multiple myeloma, one of the three major hematological cancers, and clarified the mechanism by which it promotes myeloma cell proliferation. They also developed a novel KDM5 inhibitor and showed that it inhibits cancer cell growth in a myeloma mouse model. The researchers expect that new therapies targeting KDM5A will be developed in the future.
COVID-19 vaccination: Thrombosis can be prevented by prompt treatment, resear...
17 May 2021 at 7:26am
A rare syndrome has been observed in people following vaccination against COVID-19. This involves thrombosis at unusual sites in the body, associated with a low thrombocyte count and a clotting disorder. In medical jargon, this syndrome is referred to as VITT (vaccine-induced thrombotic thrombocytopenia). Doctors at MedUni Vienna and Vienna General Hospital have now successfully treated an acute instance of this syndrome.
Zapping nerves with ultrasound lowers drug-resistant blood pressure
17 May 2021 at 5:36am
Brief pulses of ultrasound delivered to nerves near the kidney lowered blood pressure in people with drug-resistant hypertension.
Study shows online gambling soared during lockdown, especially among regular ...
17 May 2021 at 5:36am
Regular gamblers were more than six times more likely to gamble online compared to before the COVID-19 pandemic, according to new research.
Preemie boys age faster as men, study shows
17 May 2021 at 5:36am
Using an epigenetic clock, the researchers looked at the genes of 45 of those who were ELBW babies along with 47 who were normal birth weight when they were age 30 to 35 to compare their biological age, controlling for chronic health problems and sensory impairments.
How plankton hold secrets to preventing pandemics
17 May 2021 at 5:36am
Whether it's plankton exposed to parasites or people exposed to pathogens, a host's initial immune response plays an integral role in determining whether infection occurs and to what degree it spreads within a population, new research suggests.
Shortcut for dendritic cells
17 May 2021 at 5:36am
During an inflammatory response, things need to happen quickly: researchers have recently discovered that certain immune cells that function as security guards can use a shortcut to get from the tissue to lymph nodes.
Save our oceans to protect our health: Scientists call for global action plan
17 May 2021 at 5:36am
An interdisciplinary European collaboration called the Seas Oceans and Public Health In Europe (SOPHIE) Project has outlined the initial steps that a wide range of organizations could take to work together to protect the largest connected ecoInsystem on Earth. They call for the current UN Ocean Decade to act as a meaningful catalyst for global change, reminding us that ocean health is intricately linked to human health.
