Late! I’M Late For A Very Important Physics Update I’M Late! I’M Late For A Very Important Physics Update, Caterina Erdas

Osmosis Magazine

Modern physics is my only class where half the students are consistently late. It’s not a forgivable one or two minutes late, but five to fifteen. I say this as a culprit myself; I slept in late on the third day of class and didn’t go. It’s ironic, considering we spend a good portion of lecture re-defining time.

The Asu Tribe And Customs, Isabel Dilandro

Osmosis Magazine

Chandra Thapar, an Indian anthropologist, dedicated a portion of his career to the study of foreign cultures and how they relate to his native country. One in particular caught his specific attention due to its similarities in the reverence of a sacred animal, akin to how the cow is sacred to India. See below a short consolidation of his findings:

The tribe Dr. Thapar studied is called the Asu and is found on the North American continent north of the Tarahumara of Mexico.

Kennewick Man: A Rare Window Into Prehistoric Life In North America, Jack Dupuy

Osmosis Magazine

What would you do if you found a human skull on the banks of the James River? On July 28, 1996, two college students stumbled across a skull on the banks of the Columbia River in Kennewick, Washington. They believed it was a murder victim at first, but archeologists and scientists discovered that the skull was part of a nearly complete, 9,000 year-old skeleton.

Zaire Ebolavirus: A Silent Killer, Joshua Pandian

Osmosis Magazine

In 2014, the West African country Guinea experienced a major outbreak of the Ebola virus disease (EVD) that ended in 2016. Patient zero is believed to be an 18-month old boy from a small village who received the virus from bats, a potential reservoir host. After spreading rapidly through rural areas, the virus made its way to major urban centers for the first time, significantly increasing the infection and death rates.

A Creature That Has Seen It All, Dusan Vukcevic

Osmosis Magazine

What if there was a creature that is so indecisive about its habitat, that it decides to live both in rainforests and in the Antarctic? What if this creature was taking a swim in the Mariana Trench, and warming itself up at the bottom of a mud volcano? Their appearance gave them many names, so today we call them water bears, moss piglets or simply, Tardigrades. Be that as it may, the number of their names is negligible compared to the number of harsh conditions they are able to withstand. Just how resilient are these creatures?

Pollution In The James River: Fact Or Fiction?, Emily Lekas

Osmosis Magazine

The University of Richmond receives water from the James River, part of the Chesapeake Bay watershed which covers 56% of the state. Despite UR's rank of #1 Most Beautiful Campus in the Princeton Review, it is almost impossible to walk across the bridge over Westhampton Lake without noticing its opaque brown hue and circling duckweed patches. However, bodies of water do not necessarily have to have a pleasing color and clarity to be healthy.

Future Applications Of Fluorescence Lifetime Imaging Ophthalmoscopy In Neuro-Ophthalmology, Neurology, And Neurodegenerative Conditions, Daniel M. Markowitz, Elizabeth Affel, György Hajnóczky, Robert C. Sergott

Farber Institute for Neuroscience Faculty Papers

Fluorescence lifetime imaging ophthalmoscopy (FLIO) has emerged as an innovative advancement in retinal imaging, with the potential to provide in vivo non-invasive insights into the mitochondrial metabolism of the retina. Traditional retinal imaging, such as optical coherence tomography (OCT) and fundus autofluorescence (FAF) intensity imaging, focus solely on structural changes to the retina. In contrast, FLIO provides data that may reflect retinal fluorophore activity, some of which may indicate mitochondrial metabolism. This review builds upon the existing literature to describe the principles of FLIO and established uses in retinal diseases while introducing the potential for FLIO in neurodegenerative conditions.

The Interplay Between Endothelial Glycocalyx Maturity And Both The Toxicity And Intracellular Uptake Of Charged Nanoparticles, Claire A. Bridges, Lu D. Fu, Jonathan A. Yeow, Xiaojing D. Huang, Miriam D. Jackson, Rhiannon P. Kuchel, James D. Sterling, Shenda M. Baker, Megan S. Lord

Business and Information Technology Faculty Research & Creative Works

Nanoparticles are widely studied for delivering treatments to target tissues, but few have reached clinical use. Most nanoparticles encounter blood vessels on their way to target tissues. The inner surface of these vessels is lined with endothelial cells covered by a glycocalyx, an extracellular matrix rich in anionic glycans. The role of the glycocalyx in nanoparticle interactions is not well understood. Here, we demonstrate that endothelial cells need extended culture times to synthesize a mature glycocalyx. Our research shows that branched polyethyleneimine functionalized gold nanoparticles bind to endothelial cells expressing either a developing or mature glycocalyx, with the interaction involving …

Faculty, Staff and Student Publications

Significant gaps remain in our understanding of immunotherapy-related neurotoxicity in pediatric patients, largely because much of our knowledge comes from studies in adults. Accurately identifying the adverse effects of immunotherapy in children is also challenging, owing to variations in terminology and grading systems. Moreover, the manifestation of immunotherapy-related neurotoxicity differs greatly across different diseases, various modalities, dosages, and delivery methods. Combining immunotherapy with other treatments might improve outcomes but introduces new complexities and potential for increased toxicities. Additionally, pediatric patients with intracranial malignancy have unique responses to immunotherapies and distinct neurotoxicity compared to those with extracranial malignancy. Consequently, we must …
