Metabolic and immune markers as tools for risk stratification and monitoring in COVID-19

In a new study posted to the medRxiv* server scientists from Weil Cornell University and Stony Brook University in New York attempted to identify the metabolic and immune markers associated with severe COVID-19 disease using high-throughput targeted nuclear magnetic resonance (NMR) spectroscopy and high-dimensional flow cytometry. This will facilitate risk stratification, monitoring, and therapeutic interventions in COVID-19 patients.

Daily walnut consumption lowers LDL cholesterol levels and may promote cardiovascular health

Eating about ½ cup of walnuts every day for two years modestly lowered levels of low-density lipoprotein (LDL) cholesterol, known as "bad cholesterol," and reduced the number of total LDL particles and small LDL particles in healthy, older adults, according to new research published today in the American Heart Association's flagship journal Circulation.

Novel system may enable noninvasive and more precise measurement of cerebral blood flow

In order to function properly, the brain requires a steady flow of blood through the cerebral arteries and veins, which deliver oxygen and nutrients and also remove metabolic byproducts. Therefore, cerebral blood flow is considered a vital and sensitive marker of cerebrovascular function. Optical methods offer a noninvasive approach for measuring cerebral blood flow.
