Vaccination is the most effective tool to control infectious diseases. However, the evolution of vaccine resistance, exemplified by vaccine resistance in SARS-CoV-2, remains a concern. Here, we model complex vaccination strategies against a pathogen with multiple epitopes-molecules targeted by the vaccine.

Objective: To describe the rationale and design of the SIB trial, an interventional clinical trial testing the hypothesis that subcutaneous (s.c.) once-weekly semaglutide can improve intestinal permeability and reduce systemic inflammation in participants with type 2 diabetes (T2D) and obesity.

Article Synopsis
  • - The study investigates the relationship between flow-mediated dilation (FMD), a measure of endothelial function, and factors like NADPH oxidase type 2 (NOX-2) and lipopolysaccharides (LPS) in patients with COVID-19 pneumonia (CP) compared to those with community acquired pneumonia (CAP) and healthy controls.
  • - Results show that patients with CP exhibited higher levels of oxidative stress and inflammation markers (like TNF-α and IL-6) and lower FMD, indicating worsened endothelial function and increased health risks.
  • - LPS is identified as a key predictor of FMD in CP patients, suggesting that low-grade endotoxemia in COVID-19 could enhance oxidative stress and

Objective: COVID-19 clinical presentation ranges from asymptomatic infection to an inflammatory cytokine storm with multi-organ failure and fatal outcomes. The identification of high-risk patients for severe disease is crucial to plan an early treatment and intensive follow-up. We aimed to investigate negative prognostic factors in a group of patients hospitalized for COVID-19.

The surface and structural characterization techniques of three atom-thick bi-dimensional 2D-WS colloidal nanocrystals cross the limit of bulk investigation, offering the possibility of simultaneous phase identification, structural-to-morphological evaluation, and surface chemical description. In the present study, we report a rational understanding based on X-ray photoelectron spectroscopy (XPS) and structural inspection of two kinds of dimensionally controllable 2D-WS colloidal nanoflakes (NFLs) generated with a surfactant assisted non-hydrolytic route. The qualitative and quantitative determination of 1T' and 2H phases based on W 4f XPS signal components, together with the presence of two kinds of sulfur ions, S and S, based on S 2p signal and related to the formation of WS and WOS in a mixed oxygen-sulfur environment, are carefully reported and discussed for both nanocrystals breeds.
