Anticamera smontabile per lâisolamento di patogeni in ambienti di strutture sanitarie
Ă descritta una struttura componibile, e smontabile, posizionabile tra due ambienti di una struttura ospedaliera per realizzare una zona cuscinetto. La struttura Ăš provvista di pareti accoppiabili, che insieme definiscono e delimitano unâanticamera per la vestizione e la svestizione del personale sanitario. La struttura permette di erigere in poco tempo unâanticamera altrimenti non prevista nella struttura ospedaliera, ogniqualvolta si presenta la necessitĂ di disporre di anticamere per la vestizione/svestizione del personale sanitario anche in quei reparti sprovvisti in origine di anticamere adibite a questo scopo, ad esempio reparti per la lunga degenza, oppure per la dialisi. La struttura secondo la presente invenzione Ăš utilizzabile e riutilizzabile nel tempo anche in assenza di una pandemia, o prima che un virus inizi a diffondersi, per formare il personale sanitario non abituato a trattare con patogeni che richiedono una sanificazione completa di vestiti ed equipaggiamenti

An Eco-Friendly Disposable Plasmonic Sensor Based on Bacterial Cellulose and Gold
In several application fields, plasmonic sensor platforms combined with bio-receptors are intensively used to obtain biosensors. Most of these commercial devices are based on a disposable chip. Usually a gold chip, functionalized with a specific bio-receptor, inside a costly sensor system, is used. In this work, we propose a low-cost and small-size sensor system, used for monitoring a disposable plasmonic chip, based on an innovative optical waveguide made of bacterial cellulose (BC). In particular, we have sputtered gold on the green slab waveguide that is able to excite localized surface plasmon resonance (LSPR). Experimental results are presented on the capabilities of using the BC-based composite as an eco-friendly plasmonic sensor platform, which could be exploited for realizing disposable biosensors. The sensor has been used with optical fibers and simple equipment. More specifically, the fibers connect the green disposable LSPR sensor with a light source and with a spectrometer. The novel plasmonic sensing approach has been tested using two different optical waveguide configurations of BC, with and without ions inside BC
Optical Coherence Tomography Angiography Findings in Fabry Disease
Fabry disease (FD) is a X-linked recessive lysosomal storage disorder characterized by altered biodegradation of glycosphingolipids. It is a multisystem pathology, also involving ophthalmological systems that show modifications of the vessel wall due to glycosphingolipid deposits. Optical coherence tomography angiography (OCT-A) allows for an objective analysis of retinal microvasculature alterations, evaluating retinal vessel density in macular region
