Integrated longitudinal immunophenotypic, transcriptional, and repertoire analyses delineate immune responses in patients with COVID-19
2021
To understand how a protective immune response against SARS-CoV-2 develops over time, we integrated phenotypic, transcriptional and repertoire analyses on PBMCs from mild and severe COVID-19 patients during and after infection, and compared them to healthy donors (HD). A type I IFN-response signature marked all the immune populations from severe patients during the infection. Humoral immunity was dominated by IgG production primarily against the RBD and N proteins, with neutralizing antibody titers increasing post infection and with disease severity. Memory B cells, including an atypical FCRL5+ T-BET+ memory subset, increased during the infection, especially in patients with mild disease. A…
Dressings and Securement Devices of Peripheral Arterial Catheters in Intensive Care Units and Operating Theaters
2020
Background: Hemodynamic monitoring, implemented by the placement of peripheral arterial catheters (PACs), is a characterizing aspect of the intensive care units. Peripheral arterial catheters can continually detect blood pressure and quickly conduct blood sampling. The use of PACs is generally considered safe, without serious complications. Currently, only 25% of the implanted catheters are actually subject to complications, including accidental removal, dislocation, occlusion, and infection. All of these complications arise from inadequate catheter stabilization at the level of the skin. This study aimed to summarize and describe the effectiveness and characteristics of dressings and secur…
Molecular dynamics of CH4/N2 mixtures on a flexible graphene layer: adsorption and selectivity case study
2019
We theoretically investigate graphene layers, proposing them as membranes of subnanometer size suitable for CH4/N2 separation and gas uptake. The observed potential energy surfaces, representing the intermolecular interactions within the CH4/N2 gaseous mixtures and between these and the graphene layers, have been formulated by adopting the so-called Improved Lennard-Jones (ILJ) potential, which is far more accurate than the traditional Lennard-Jones potential. Previously derived ILJ force fields are used to perform extensive molecular dynamics simulations on graphene's ability to separate and adsorb the CH4/N2 mixture. Furthermore, the intramolecular interactions within graphene were explic…
