Central retinal artery occlusion can be a warning sign of other vascular issues

While most people think of strokes affecting the brain, they can also affect the eye. Central retinal artery occlusion (CRAO) is a rare form of acute ischemic stroke that occurs when blood flow is blocked to the main artery of the eye.

Coronavirus deranges the immune system in complex and deadly ways

There's a reason soldiers go through basic training before heading into combat: Without careful instruction, green recruits armed with powerful weapons could be as dangerous to one another as to the enemy.

Study suggests a new way to detect heart disease through non-invasive tool

In a new study from Shiley Eye Institute at UC San Diego Health, researchers have identified a potential new marker that shows cardiovascular disease may be present in a patient using an optical coherence tomography (OCT) scan -- a non-invasive diagnostic tool commonly used in ophthalmology and optometry clinics to create images of the retina.

Newly developed maps show how human brains are kept nourished

Our brains are non-stop consumers. A labyrinth of blood vessels, stacked end-to-end comparable in length to the distance from San Diego to Berkeley, ensures a continuous flow of oxygen and sugar to keep our brains functioning at peak levels.

How SARS-CoV-2 proteins affect vascular functionality

The study, published on the pre-print server medRxiv, can pinpoint and isolate how each of the SARS-CoV-2 proteins independently affects the endothelial response and directly gauge endothelial functionality.

Efficacy of polymeric nano-micelles depends on expression level of c-Myc

The Innovation Center of NanoMedicine (Director General: Prof. Kazunori Kataoka, Location: Kawasaki in Japan, Abbreviation: iCONM) reported in ACS Nano (Impact Factor: 14.588 in 2019) together with the group of Prof. Yu Matsumoto of Otorhinolaryngology and Head and Neck Surgery (Prof. Tatsuya Yamasoba) and the group of Prof. Horacio Cabral of the Department of Bioengineering (Prof. Ryo Miyake) in the University of Tokyo that the efficacy of polymeric nano-micelles with different drug activation profile depends on the expression level of c-Myc, one of the major proto-oncogene, has been developed.

FDA permits marketing of new device to protect athletes from harmful effects of head impacts

Today, the U.S. Food and Drug Administration authorized marketing of a new device intended to be worn around the neck of athletes aged 13 years and older during sports activities to aid in the protection of the brain from the effects associated with repetitive sub-concussive head impacts.

Structure of SARS-CoV-2 envelope protein-epithelial cell junction protein complex explains virulence

A new study by researchers at Brookhaven National Laboratory and Stony Brook University in the U.S. describes the key interaction between the viral envelope (E) protein and the human cell junction protein, PALS1. The latter is necessary to establish and maintain cell polarity and tight junctions between cells.

SARS-CoV-2 does not infect the entire body in the same way, finds study

COVID-19, the disease caused by the pandemic coronavirus SARS-CoV-2, is primarily regarded as a respiratory infection. Yet the virus has also become known for affecting other parts of the body in ways not as well understood, sometimes with longer-term consequences, such as heart arrhythmia, fatigue and "brain fog."

New surgical procedure reduces the rate of recurrent strokes among atherosclerotic patients

A surgical procedure advanced and studied by vascular neurosurgeons at Cedars-Sinai dramatically reduced the rate of recurrent strokes among patients with atherosclerotic disease, a new study shows.

Innate immune system overreacts in patients with severe COVID-19

In patients with severe COVID-19, the innate immune system overreacts. This overreaction may underlie the formation of blood clots (thrombi) and deterioration in oxygen saturation that affect the patients.
