While this study requires validation in a bigger patient group, the initial results suggest that one dose of ivermectin given to mild COVID-19 patients reduced viral load and the duration of symptoms such as cough and loss of smell and taste.
Research suggests that a build-up of abnormal microRNAs could be behind the increased risk for Alzheimer’s disease seen in patients who have experienced traumatic brain injury.
The study shows that endogenous mis-spliced RNA in tumor cells mimics an RNA virus, leading tumor cells to self-destruct as if fighting an infection.
About half of the patients who were very sick with COVID-19 were exhibiting a combination of high levels of both the dangerous antibodies and super-activated neutrophils, which are destructive, exploding white blood cells.
Dubbed TriSilix, the chip performs a miniature version of polymerase chain reaction (PCR) testing on bodily fluids, feces, or environmental samples, according to the scientists at Imperial College London who developed the new technology.
Moderna said its vaccine candidate produced neutralizing antibodies in older and elderly adults, while Regeneron said REGN-COV2 rapidly reduced viral load as well as time to alleviate symptoms in non-hospitalized patients.
The study is one of the first longitudinal analyses to show that people who were seropositive—that is, they had produced antibodies against the virus that causes COVID-19—become seronegative, which means there were no detectable antibodies after a certain point.
Normally, confirming a pneumonia diagnosis requires growing bacterial samples from patients in a lab, which is time-consuming. The new test can identify 52 different pathogens, and can be done in around four hours, without needing to grow the bacteria.
Autopsies have shown the presence of SARS-CoV-2 RNA and protein in anatomically distinct regions of the nasopharynx and brain, suggesting it enters the brain through the nose, and may inform diagnosis and measures to prevent infection.
The researchers trained a natural language processing model to analyze patterns found in genetic sequences, which allowed it to predict new sequences that have new functions but still follow the biological rules of protein structure.
With guidelines for noninvasive prenatal testing expanding and payers reimbursing for these screenings, researchers search for new testing methods. Noninvasive prenatal testing brought genetics to the very core of clinical practice.
In the 1990s, Elissa Levin proposed a master’s thesis on using the Internet to extend the reach of genetic counselors. Quickly, her committee shut...
When Congress reconvenes in January, the lengthy docket of action items is expected to include proposed solutions to the years-long conundrum over how to...
Michael Heltzen, CEO and co-founder of Cardea Bio, a San Diego startup integrating tiny bits of biology into modern electronics, believes that the way...
