Alterations in Carotid Parameters in ApoE–/– Mice Treated with a High-Fat Diet: A Micro-ultrasound Analysis

Information on the common carotid artery and cerebral microcirculation can be obtained by micro-ultrasound (µUS). The aim of the study described here was to investigate high-fat diet-induced alterations in vascular parameters in ApoE–/– mice. Twenty-two ApoE–/– male mice were examined by µUS and divided into the standard diet (ApoE–/–_SD) and high-fat diet (ApoE–/–_HF) groups. The µUS examination was repeated after 4 mo (T₁). Carotid stiffness, reflection magnitude and reflection index were measured; the amplitudes of the first (W₁) and second (W₂) local maxima, the local minimum (W_b) and the reflection index (RI_WIA?=?W_b/W₁) were assessed with wave intensity analysis. At T₁, ApoE–/–_HF mice had increased carotid stiffness (1.48 [0.36] vs. 1.88 [0.51]) and reflection magnitude (0.89 [0.07] vs. 0.94 [0.07]) values. Longitudinal comparisons highlighted increases in carotid stiffness for ApoE–/–_HF mice (from 1.37 [0.25] to 1.88 [0.51] m/s) but not for ApoE–/–_SD mice (from 1.40 [0.62] to 1.48 [0.36] m/s). ApoE–/–_HF mice exhibited carotid artery stiffening and increased wave reflections.     

Cytologic and histologic samples from patients infected by the novel coronavirus 2019 SARS-CoV-2: An Italian institutional experience focusing on biosafety procedures

The 2019 coronavirus pandemic, which started in Wuhan, China, spread around the globe with dramatic and lethal effects. From the initial Chinese epicenter, the European diaspora taxed the resources of several countries and especially those of Italy, which was forced into a complete social and economic shutdown. Infection by droplets contaminating hands and surfaces represents the main vehicle of diffusion of the virus. The common and strong efforts to contain the pandemic have relevant effects on the management of samples from histopathology laboratories. The current commentary reports and focuses on the protocols and guidelines in use at a large tertiary Italian hospital that accordingly are proposed for adoption in Italian laboratories as a potential model for national guidelines for the coronavirus emergency.
