Viruses live – if you can call it that – to replicate themselves. They hijack cells, including our own, and use them to make copies of themselves.
But every time a virus like the one that causes COVID-19 copies itself, as it does millions of times inside each infected person, mistakes can happen. Instead of perfectly copying its 29,811 bases, the four-letter alphabet used to describe its genetic code, a wrong letter sneaks in.

(Philadelphia, PA) - Like a failing fuel pump that causes a loss of engine power in a car, a diseased heart can take a serious toll on the body s performance. For some patients, tasks like walking up a flight of stairs or walking across a room eventually turn into exhausting endeavors. This is because, over time, regardless of the underlying cause, heart damage typically progresses, owing to a constant barrage of oxidative stress and toxic lipids that alter heart cell energetics and, ultimately, the ability of the heart to function normally.
Oxidative stress occurs when harmful oxygen-containing molecules outnumber helpful antioxidants, leading to damaging reactions with proteins, DNA, and other cell components. Now, in two new studies, researchers at the Lewis Katz School of Medicine at Temple University (LKSOM) show that in the heart, one molecule in particular, Kruppel-like factor (KLF)-5, single-handedly fuels both the generation of oxidizing molecules and the accumul
2021 Geisel Martin Luther King, Jr. Celebration
15th Annual Geisel MLK Health Equity Celebration Of all the forms of inequality, injustice in health is the most shocking and the most inhumane. - Reverend Dr. Martin Luther King, Jr.
Statement of Purpose –
The COVID-19 pandemic has exposed the inequities that have long existed within health and society. Across the years, many have pointed to the current system and pushed for a more inclusive future. A future that is made more urgent by the current health crisis. As aspiring medical professionals, we the students of the Geisel School of Medicine, would like to ask, where do we go from here? What does healing look like for those most marginalized in healthcare? What can we do so that all of our communities can begin to heal? How can we remain vigilant as the effects of the pandemic continue?

Medications to treat high blood pressure did not affect outcomes among patients hospitalized with COVID-19, found an international team led by researchers in the Perelman School of Medicine at the University of Pennsylvania.
Medications to treat high blood pressure did not affect outcomes among patients hospitalized with COVID-19, found an international team led by researchers in the Perelman School of Medicine at the University of Pennsylvania. The study, published today in The Lancet Respiratory Medicine, is the first randomized controlled trial to show there is no risk for patients continuing these medications while hospitalized for COVID-19.
As part of the REPLACE COVID trial, investigators examined whether ACE inhibitors (ACEIs) or Angiotensin Receptor Blockers (ARBs) two classes of medications to treat high blood pressure could help mitigate complications or lead to more severe symptoms. More than 49 million U.S. adults take medication to treat hypertension, a
