by Thamarasee Jeewandara , Medical Xpress Optimization of microswimmer shape for targeted drug delivery. Illustration of a future use case for the medical microrobots emphasizing an important design tradeoff. Double-helical magnetic microswimmers with filled internal cores are 3D-printed as concentrated drug-carrying bodies. Three morphological derivatives of the same design are tested with the same body...
An investigational vaccine, mRNA-1273, designed to protect against SARS-CoV-2, the virus that causes coronavirus disease 2019 (COVID-19), was generally well tolerated and prompted neutralizing antibody activity in healthy adults, according to interim results published online in The New England Journal of Medicine. The ongoing Phase 1 trial is supported by the National Institute of Allergy...
RADIOLOGICAL SOCIETY OF NORTH AMERICA OAK BROOK, Ill. (July 16, 2020) – COVID-19 is associated with life-threatening blood clots in the arteries of the legs, according to a study published in Radiology. Researchers said COVID-19 patients with symptoms of inadequate blood supply to the lower extremities tend to have larger clots and a significantly higher...
by Columbia University Irving Medical Center After only a few days caring for critically ill COVID-19 patients at the start of the outbreak in New York City, Aakriti Gupta, MD, realized that this was much more than a respiratory disease. “I was on the front lines right from the beginning. I observed that patients were...
Smoking habits trump asthma, obesity in risk factors for otherwise healthy population UNIVERSITY OF CALIFORNIA – SAN FRANCISCO As the number of young adults infected with the coronavirus surges throughout the nation, a new study by researchers at UCSF Benioff Children’s Hospitals indicates that youth may not shield people from serious disease. The study looked...
SP-2577 could enable the immune system to attack ovarian cancer; clinical trials for patients expected soon THE TRANSLATIONAL GENOMICS RESEARCH INSTITUTE PHOENIX, Ariz. — July 10, 2020 — A drug known as SP-2577 could help enable the body’s own immune system to attack ovarian cancer, according to a study led by the Translational Genomics Research...
by Max Planck Society As we age, the immune system gradually becomes impaired. One aspect of this impairment is chronic inflammation in the elderly, which means that the immune system is constantly active and sends out inflammatory substances. Such chronic inflammation is associated with multiple age-related diseases including arthritis and Alzheimer’s disease, and impaired immune...
In a new study, patients who received single intravenous dose of tocilizumab were also more likely to leave the hospital or be off a ventilator within a month, despite double the risk of additional infection. Critically ill COVID-19 patients who received a single dose of a drug that calms an overreacting immune system were 45%...
Researchers have developed a way to pull HIV out of the latent reservoir making the virus visible to the immune system and providing the potential to be killed by treatment. Part of what has made HIV infection so difficult to cure, is that once the virus enters the body, some of it hides dormant inside...
A pair of recent studies found that people with Type A blood are no more at risk of getting the virus or falling dangerously ill than others, contradicting preliminary evidence based on a relatively small sample of people. Over the past few months, after looking at thousands of additional patients with Covid-19, scientists are reporting...
