A one-liter intravenous infusion of normal saline was applied to the participants to observe the hemodynamic variations. Blood viscosity was measured before and after the injection of normal saline to apply the blood properties on the CFD modeling. Blood viscosity, shear rate, and wall shear stress were visually and quantitatively shown for the comparison between before and after the infusion of normal saline. Statistical analyses were performed to confirm the difference between the before and after groups.Results: After the infusion of normal saline, decreased blood viscosity was observed in the whole carotid artery. At the internal carotid artery, the recirculation zone with low intensity was found after the injection of normal saline. Increased shear rate and reduced wall shear stress was observed at the carotid bifurcation and internal carotid artery. The hemodynamic differences between before and after groups were statistically significant.Conclusions: The infusion of normal saline affected not only the overall changes of blood flow in the carotid artery but also the decrease of blood viscosity.Reference:Lee UY, Kim CI, Chung GH, Jung J, Kwak HS.

Abstract
Immune checkpoint inhibitors (ICIs) show limited efficacy in non-small cell lung cancer (NSCLC), highlighting the need for predictive biomarkers. Here we prospectively analysed serial plasma samples from 34 ICI-treated advanced NSCLC patients (plus 30 validation samples) using the Olink Immuno-Oncology panel. We assessed dynamic proteomic

A new neurologist inspires me to consider my treatment's side effects
I went to see the neurologist last month for a routine follow-up for my multiple sclerosis (MS), anticipating no changes.
After all, I’ve been on the same medication for my MS, fingolimod (which often goes by the brand name Gilenya), for about 10 years. I feel my MS is stable, an
