A phase I trial of cyclosporine for hospitalized patients with COVID-19.

BACKGROUNDCOVID-19 remains a global health emergency with limited treatment options, lagging vaccine rates, and inadequate healthcare resources in the face of an ongoing calamity. The disease is characterized by immune dysregulation and cytokine storm. Cyclosporine A (CSA) is a calcineurin inhibitor that modulates cytokine production and may have direct antiviral properties against coronaviruses.

Effects of Flow and Bulk Vesicle Concentration on Supported Lipid Bilayer Formation.

Supported lipid bilayers (SLBs) have been used extensively in a variety of biotechnology applications and fundamental studies exploring lipid behavior. Despite their widespread use, various physicochemical parameters have yet to be thoroughly investigated for their impact on SLB formation. In this work, we have studied the importance of flow in inducing the rupture of surface adsorbed chicken egg-derived l-α-phosphatidylcholine (egg PC) vesicles on silica and gold surfaces via quartz crystal microbalance with dissipation monitoring (QCM-D).

Size dependence of gold nanoparticle interactions with a supported lipid bilayer: A QCM-D study.

Knowledge of nanoparticle (NP)-membrane interactions is important to advances in nanomedicine as well as for determining the safety of NPs to humans and the ecosystem. This study focuses on a unique mechanism of cytotoxicity, cell membrane destabilization, which is principally dependent on the nanoparticle nature of the material rather than on its molecular properties. We investigated the interactions of 2, 5, 10, and 40nm gold NPs with supported lipid bilayer (SLB) of L-α-phosphatidylcholine using quartz crystal microbalance with dissipation monitoring (QCM-D).
