Objective: No-visitor policies adopted to prevent coronavirus disease-19 (COVID-19) spread in hospital wards have deeply impacted communication with patients and their relatives. Whereas in pre-COVID-19 era family-clinician meetings were held in person, during the pandemic interactions often took place over the phone, frequently causing feelings of uncertainty and distress to the close ones at home. The goal of this study was to assess and improve the effectiveness of structured telephone-based communication with hospitalized onco-hematological patients' relatives in COVID-19 era.

- * High hydrostatic pressure (HHP) is shown to disrupt protein aggregates, allowing for better solubilization and refolding, with TsnC serving as a model protein for the experiments.
- * Optimal conditions for refolding were identified, achieving an 81% yield of biologically active TsnC, paving the way for future efficient HHP-based processes for other proteins.
The production of recombinant proteins is an essential tool for the expansion of modern biological research and biotechnology. The expression of heterologous proteins in Escherichia coli often results in an incomplete folding process that leads to the accumulation of inclusion bodies (IB), aggregates that hold a certain degree of native-like secondary structure. High hydrostatic pressure (HHP) impairs intermolecular hydrophobic and electrostatic interactions, leading to dissociation of aggregates under non-denaturing conditions and is therefore a useful tool to solubilize proteins for posterior refolding.

Recurrence was confirmed by histology in 18 cases and excluded in 25 cases. Sensitivity, specificity, positive and negative predictive values, and accuracy were as follows: 44.
