Drug-Coated Balloons in Autologous Vein Peripheral-Distal Bypass Graft Maintenance: Advancements and Potential Impact.

Introduction: Initial surgical revascularization has a recognized primary role in patients with critical limb-threatening ischemia with a high-quality great saphenous vein for conduit. However, approximately one-third of lower extremity vein grafts develop lesions threatening graft patency. Traditional treatments have limitations, highlighting the need for innovative solutions.

Incorporating art into a biology course: a student-curated art exhibition about COVID-19.

Incorporating art into science, technology, engineering, and mathematics (STEM) courses can be an effective way to help students understand scientific concepts and think about those concepts more holistically. Additionally, art can be used to inform the public about scientific issues. To explore this topic more fully, we developed an assignment for an upper-level biology course in which students curated an art exhibition focused on the 2019 coronavirus disease, COVID-19.

Early Stages of Metal Corrosion in Coastal Archaeological Sites: Effects of Chemical Composition in Silver and Copper Alloys.

In this study, metal disks with different chemical composition (two Ag-based alloys and three Cu-based alloys) were buried in the soil of coastal archaeological sites for a period of 15 years. The aim was to naturally induce the growth of corrosion patinas to obtain a deeper insight into the role of alloying elements in the formation of the patinas and into the degradation mechanisms occurring in the very early stages of burial. To reach the aim, the morphological, compositional and structural features of the patinas grown over 15 years were extensively characterized by optical microscopy, field emission scanning electron microscopy coupled with energy dispersive spectrometry, X-ray diffraction and micro-Raman spectroscopy.

Reproducing bronze archaeological patinas through intentional burial: A comparison between short- and long-term interactions with soil.

The reproduction of archaeological corrosion patinas is a key issue for the reliable validation of conservation materials before their use on cultural objects. In this study, bronze disks were intentionally buried for 15 years in the soil of the archaeological site of Tharros, both in laboratory and , with the aim of reproducing corrosion patinas typical of archaeological artifacts to be used as representative surfaces for testing novel cleaning gels. The microstructural, microchemical and mineralogical features of the patinas were analyzed by a multianalytical approach, based on optical microscopy (OM), field emission scanning electron microscopy coupled with energy dispersive spectrometry (FE-SEM-EDS) and X-ray diffraction (XRD).
