Abstract

The controlled insertion of electronic states within the band gap of semiconductor nanocrystals (NCs) is a powerful tool which enables to engineer their physical properties. One compelling example is represented by metal chalcogenide NCs incorporating heterovalent p-type impurities such as d10 coinage metals (Cu+, Ag+, or Au+). In this type of nanostructures the interplay between the dopant and the host semiconductor energy levels leads in the ultra-fast capture of the hole by the localized state of the dopant leading to the so-called "acceptor-bound" excitons. The control of this paradigm unlocked technologically relevant functionalities, such as Stokes-shift between the emission and the absorptionspectra, extended luminescence lifetimes, photomagnetic behaviors, and enhanced electrical transport. To date, although conceptually analogous to hole-management schemes, the opposite "donor-bound" exciton scheme using aliovalent elements adopted to n-doped NCs (e.g., Al3+ and In3+ in) has not been realized due to the natural propensity of such cations to produce shallow donor states that inject electrons directly in the CB. Here, we exploit the propensity of metal sulfides to present sulfur vacancies (VS) that introduce a localized level pinned about 1 eV below the CB to produce a model system for "donor-bound" excitons in CdSeS NCs. The investigation of the optical and magneto-optical properties of these NCs revealed that the VS state is responsible for the ultrafast capture of electron in the CB which can then either decay non-radiatively or recombine with the VB photohole leading to long-lived, Stokes-shifted emission with size-tunable energy. Moreover, VS-localized electrons are almost unaffected by trapping, and suppression of thermal quenching boosts the emission efficiency to 85%. Magneto-optical measurements indicate that the VS are not magnetically coupled to the NC bands and that the polarization properties are determined by the spin of the valence-band photo-hole, whose spin flip is massively slowed down due to suppressed exchange interaction with the donor localized electron.

Abstract

The implementation of FIT programs reduces incidence and mortality from CRC in the screened subjects. The ultimate efficacy for CRC morbidity and mortality prevention in a FIT program depends on the colonoscopy in FIT+ subjects that has the task of detecting and removing these advanced lesions. Recently, there has been growing evidence on factors that influence the quality of colonoscopy specifically withing organized FIT programs, prompting to dedicated interventions in order to maximize the benefit/harm ratio of post-FIT colonoscopy. This document focuses on the diagnostic phase of colonoscopy, providing indications on how to standardise colonoscopy in FIT+ subjects, regarding timing of examination, management of antithrombotic therapy, bowel preparation, competence and sedation., Competing Interests: Conflict of Interest None., (Copyright © 2023 Editrice Gastroenterologica Italiana S.r.l.

Abstract

Background and Aim: Endoscopic ultrasound-guided gastroenterostomy (EUS-GE) for the treatment of gastric outlet obstruction (GOO) has been actually performed only with one type of electrocautery lumen-apposing metal stents (EC-LAMS). We aimed to evaluate the safety, technical and clinical effectiveness of EUS-GE using a newly available EC-LAMS in patients with malignant and benign GOO., Materials and Methods: Consecutive patients who underwent EUS-GE for GOO using the new EC-LAMS at five endoscopic referral centers were retrospectively evaluated. Clinical efficacy was determined utilizing the Gastric Outlet Obstruction Scoring System (GOOSS)., Results: Twenty-five patients (64% male, mean age 68.7 ± 9.3 years) met the inclusion criteria; 21 (84%) had malignant etiology. Technically, EUS-GE was successful in all patients, with a mean procedural time of 35 ± 5 min. Clinical success was 68% at 7 days and 100% at 30 days. The mean time to resume oral diet was 11.4 ± 5.8 h, with an improvement of at least one point of GOOSS score observed in all patients. The median hospital stay was 4 days. No procedure-related adverse events occurred. After a mean follow-up of 7.6 months (95% CI 4.6-9.2), no stent dysfunctions were observed., Conclusion: This study suggests EUS-GE can be performed safely and successfully using the new EC-LAMS. Future large multicenter prospective studies are needed to confirm our preliminary data., Competing Interests: Conflict of interest Author B.M. is has received research grants from Taewoong Dott.
