Multivalent-Ion versus Proton Insertion into Nanostructured Electrochromic WO from Mild Aqueous Electrolytes.

Mild aqueous electrolytes containing multivalent metal salts are currently scrutinized for the development of ecosustainable energy-related devices. However, the role of soluble multivalent metal ions in the electrochemical reactivity of transition metal oxides is a matter of debate, especially when they are performed in protic aqueous electrolytes. Here, we have compared, by means of (spectro)electrochemistry, the reversible electrochromic reduction of transparent nanostructured γ-WO thin films in mild aqueous electrolytes of various chemical composition and pH.

Does the bank-firm human relationship still matter for SMEs? The game-changing role of digitalization.

Noteworthy contributions have highlighted that human contact is a considerable factor in bank-firm relationships. It allows the acquisition of soft information, which alleviates information asymmetries and increases the use of bank debt. The advent of digital technologies in the information collection process open new horizons and change the role of personal contacts in bank-firm interactions, as entrepreneurs visit bank branches less frequently.

SARS-COV-2 Pandemic for Patients with Chronic Obstructive Peripheral Arterial Disease: Impact of Interruption to Access According to Gender in a Single Center Experience.

Background: This retrospective study aims to evaluate the impact of interrupted services for peripheral arterial disease (PAD) patients and especially women in a single north-eastern Italian center over a period of 3 months prior to the pandemic, during the first (2020) and the second (2021) wave of contagion in northern Italy.

Methods: Patients with PAD at Rutherford stages 3 to 6 that required revascularization between March 2019 and March 2021 were classified into 3 groups, according to the period of treatment: the prepandemic period, the pandemic-20 period, and the pandemic-21 period.

Results: Twenty-eight patients were treated in the prepandemic period, 21 in the pandemic-20 period, and 39 in the pandemic-21 period.

Elastomeric Cardiowrap Scaffolds Functionalized with Mesenchymal Stem Cells-Derived Exosomes Induce a Positive Modulation in the Inflammatory and Wound Healing Response of Mesenchymal Stem Cell and Macrophage.

A challenge in contractile restoration of myocardial scars is one of the principal aims in cardiovascular surgery. Recently, a new potent biological tool used within healing processes is represented by exosomes derived from mesenchymal stem cells (MSCs). These cells are the well-known extracellular nanovesicles released from cells to facilitate cell function and communication.

Electrospun PCL-Based Vascular Grafts: In Vitro Tests.

Background: Electrospun fibers have attracted a lot of attention from researchers due to their several characteristics, such as a very thin diameter, three-dimensional topography, large surface area, flexible surface, good mechanical characteristics, suitable for widespread applications. Indeed, electro-spinning offers many benefits, such as great surface-to-volume ratio, adjustable porosity, and the ability of imitating the tissue extra-cellular matrix.

Methods: we processed Poly ε-caprolactone (PCL) via electrospinning for the production of bilayered tubular scaffolds for vascular tissue engineering application.
