Can the additive tree expand machine learning in medicine?

Penn Today | October 07, 2019

When health care providers order a test or prescribe medicine, they want to be 100 percent confident in their decision. That means being able to explain their decision and study it over, depending upon how a patient responds. As artificial intelligence’s footprint increases in medicine, that ability to check work and follow the path of a decision can become a bit muddied. That’s why the discovery of a once-hidden through-line between two popular predictive models used in artificial intelligence opens the door much wider to confidently spread machine learning further throughout health care. “In medicine, the cost of a wrong decision can be very high,” says one of the study’s authors, Lyle Ungar, a professor of computer and information science in the School of Engineering and Applied Science. “In other industries, for example, if a company is deciding which advertisement to show its consumers, they likely don’t need to double-check why the computer selected a given ad. But in health care, since it’s possible to harm someone with a wrong decision, it’s best to know exactly how and why a decision was made.”

Antibodies are a critical feature of the human adaptive immune response. New immunotherapies require the production of selective and non-autoimmunogenic antibodies. These engineered antibodies can convert proteins from a threat recognition agent, into a disease-fighting form. Transgenic mice allow researchers to create “humanized” mice with human equivalents of murine antibody-coding genes. High throughput production of chimeric antibodies with murine-constant regions and human-variable regions has tremendous implications for both research and clinical purposes.

Pfizer, Moderna urge calm as they launch tests of vaccines against mutated COVID-19

Pfizer | December 29, 2020

After a changed, quick spreading variation of COVID-19 in the U.K. disturbed worldwide travel throughout the end of the week, an upsetting inquiry arose: Will the new antibodies from Pfizer and Moderna neutralize this startling new strain of the infection? Presently the two organizations, alongside Pfizer's COVID-19 accomplice BioNTech, are racing to quiet an apprehensive public. They're dispatching new investigations intended to demonstrate their mRNA-based shots will fight off the new Covid strain, while at the same time communicating certainty this new antibody innovation is ideal for ensuring against quickly changing infections. Pfizer and BioNTech have tried their antibody "for its capacity to kill various freak strains. Until now, we have discovered steady inclusion of the multitude of strains tried," they said in an assertion. The organizations are currently gathering information from individuals who have gotten the shot to decide how well they "might have the option to kill the new strain from the U.K.," Pfizer added. Moderna didn't promptly react to a solicitation for input yet said in an assertion gave to other news sources that it expects "that the Moderna immunization instigated insusceptibility would be defensive against the variations as of late portrayed in the U.K.," and that it "will play out extra tests in the coming a long time to affirm this desire." Pfizer brought up that when SARS-CoV-2, the infection that causes COVID-19, first arose a year prior, it was clear there was more than one strain of it, and that it was transforming as it spread. SARS-CoV-2 is a RNA infection, and all things considered, it has "astoundingly high [mutation] rates" on the grounds that the chemicals it utilizes for replication are "inclined to mistakes when making new infection duplicates," the organization said. "One reason Pfizer and BioNTech decided to use a mRNA stage is a direct result of the potential for the adaptability of the innovation in contrast with customary immunization advancements," including the capacity to change the RNA arrangement in the antibody, should a strain arise that is not covered by the current shot," Pfizer added.
