Novel Coronavirus 2019 (2019-nCoV)

Read Show Notes

The novel coronavirus 2019 (2019-nCoV) is a respiratory virus originating from Wuhan, China that has spread to many countries, causing an outbreak. Headlines on its rapid spread have dominated media and news sites globally, and a lot remains unknown about how the virus infects humans, how it spreads, and how deadly it really is. In this episode of Beyond the Abstract, Ellen and Derek tackle a paper deposited in bioRxiv on how 2019-nCoV infects human cells with similarities to the SARS coronavirus. They may answer questions you have related to the outbreak and put many commonly cited statistics into perspective. Finally, they comment on a new age of science sharing through bioRxiv, a preprint server that has allowed for quicker and cheaper dissemination of science.

This episode was recorded on February 11th, 2020. Shortly after recording this episode, the WHO announced that the virus will be renamed severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) causing coronavirus disease 2019 (COVID-19).

The Golden Phage

Read Show Notes

Alcoholic hepatitis is a severe, life-threatening type of liver disease, but not for all patients. Some patients seem to have worse outcomes than others, but what differentiates these patients and how do we treat them? In this episode, Derek and Ellen invite Sam McCright, an MD/PhD student at the University of Pennsylvania studying the microbiome, to talk about a new paper that discovers the potential bacterial culprit behind the most severe cases of alcoholic hepatitis. Even more, these scientists have found new ways to combat these bacteria. Instead of using antibiotics, they use phages, which are like little homing missiles that can target and destroy specific bacteria and are found in sewage. The secret to treating this disease just might literally be a load of crap.

The Cancer Conundrum

Read Show Notes

One in eight women will be diagnosed with invasive breast cancer, but how exactly breast cancer metastasizes and spreads to other organs still isn't clear. E-cadherin is a protein that acts as 'molecular glue' that helps cancer cells stick together, but controversy exists within the cancer field about its exact role in cancer spread. This week on Beyond the Abstract, Derek and Ellen take on a paper that lays to rest the role of E-cadherin in breast cancer metastasis. Listen in as they talk about this important paper that definitively addresses this issue once and for all.

Padmanaban et al. E-cadherin is required for metastasis in multiple models of breast cancer. Nature, 2019. 573(7774):439-444. PMID: 31485072.

Achy Breaky Cytoskeleton

Read Show Notes

Your heart beats over 100,000 times a day and over 2 billion times a lifetime. The heart keeps up with wear and tear because it has a strong yet flexible cytoskeleton, the 'framework' of the cell. But what happens when the cytoskeleton malfunctions, and more importantly, how do we fix it? On this episode of Beyond the Abstract, Derek and Ellen chat with cell biologist and PhD candidate Brittany MacTaggart about alterations that happen to the cytoskeleton during heart failure and how these changes affect how the heart functions.

The Clot Thickens

Read Show Notes

Deep vein thromboses (DVTs) are clots in the blood system that can travel from the legs to the lungs, causing severe damage and even death. This week on Beyond the Abstract, Ellen and Derek are joined by John Welsh, PhD as they dive into John's recent paper on how DVTs are formed. To our surprise, Dr. Welsh discusses how current measures in the hospital to prevent DVTs may not work as well as we think they do. Finally, we talk about Dr. Welsh's company, which is currently building a device that would better solve this problem.

Welsh et al. Hemodynamic regulation of perivalvular endothelial gene expression prevents deep vein thrombosis. Journal of Clinical Investigation, 2019. 129(12). PMID: 31710307.

Beyond the Abstract
Science and research for everyone
Hey science nerds! Welcome to Beyond the Abstract, a science podcast dedicated to discussion of the coolest cutting edge, basic science research papers in a way that just about anyone can understand. We're your hosts, Derek and Ellen, two MD/PhD students at the University of Pennsylvania who are passionate about science communication and bridging the gap between science and medicine.

In each episode, we’ll dive into a paper and talk about the experiments these scientists did, what it means for the future of research, and even potential impacts on human health and medicine. We've invited experts in these fields to help us understand and dissect these complicated but impactful papers.

We can't wait to share all this cool science with you.
