Interplay of Quantum Confinement and Strain Effects in Type I to Type II Transition in GeSi Core-Shell Nanocrystals.

The electronic properties of hydrogenated, spherical SiGe and GeSi core-shell nanocrystals, with a diameter ranging from 1.8 to 4.0 nm, are studied within density functional theory.

Evolution of the Electronic and Optical Properties of Meta-Stable Allotropic Forms of 2D Tellurium for Increasing Number of Layers.

In this work, ab initio Density Functional Theory calculations are performed to investigate the evolution of the electronic and optical properties of 2D Tellurium-called Tellurene-for three different allotropic forms (α-, β- and γ-phase), as a function of the number of layers. We estimate the exciton binding energies and radii of the studied systems, using a 2D analytical model. Our results point out that these quantities are strongly dependent on the allotropic form, as well as on the number of layers.

Recovery of gastric function in patients affected by chronic atrophic gastritis using l-cysteine (Acetium®): one year survey in comparison with a control group.

Background And Aim: Chronic Atrophic Gastritis (CAG) is a precancerous condition for gastric cancer (GC) as single risk factor, being a consequence of a previous Helicobacter pylori (Hp) infection or based on autoimmune mechanisms. Achlorhydria plays an important role towards the formation of a class I carcinogen, acetaldehyde, after food intake. L-cysteine has been claimed to be able to bind in a covalent way acetaldehyde when administered at means.

Fusion radiology in interventional endoscopy (FRIend): a new approach for pancreatic fluid collections.

 Fusion imaging consists of overlaying preoperative imaging over live fluoroscopy, providing an augmented live guidance. Since 2017, we have been using a new hybrid operating room (Discovery IGS 740 OR, GE Healthcare) for biliopancreatic endoscopy, combining fusion imaging with traditional endoscopic ultrasound (EUS). This study aimed to assess the advantages that fusion imaging could bring to EUS-guided drainage of post-pancreatitis fluid collections.

Linked-color imaging versus white-light colonoscopy in an organized colorectal cancer screening program.

Background And Aims: Linked-color imaging (LCI), a new image-enhancing technology emphasizing contrast in mucosal color, has been demonstrated to substantially reduce polyp miss rate as compared with standard white-light imaging (WLI) in tandem colonoscopy studies. Whether LCI increases adenoma detection rate (ADR) remains unclear.

Methods: Consecutive subjects undergoing screening colonoscopy after fecal immunochemical test (FIT) positivity were 1:1 randomized to undergo colonoscopy with LCI or WLI, both in high-definition systems.

Use, effectiveness and tolerability of budesonide-MMX in ulcerative colitis: A real-life experience.

Background: Budesonide-MMX has an established role in the management of relapsing mild-to-moderate ulcerative colitis. Data regarding effectiveness and tolerability in real-life clinical practice are limited.

Aim: The aim of this study was to assess the use of budesonide-MMX in ulcerative colitis, as well as short-term effectiveness and tolerability in real-life practice.

Player Session Rating of Perceived Exertion: A More Valid Tool Than Coaches' Ratings to Monitor Internal Training Load in Elite Youth Female Basketball.

Purpose: To monitor elite youth female basketball training to verify whether players' and coaches' (3 technical coaches and 1 physical trainer) session rating of perceived exertion (s-RPE) has a relationship with Edwards' method.

Methods: Heart rate of 15 elite youth female basketball players (age 16.7 [0.

Endoscopic ultrasound-guided biliary drainage for malignant biliary obstruction after failed ERCP in low performance status patients.

Background: Endoscopic retrograde cholangiopancreatography (ERCP) with the placement of a biliary stent is the treatment of choice for palliation of malignant obstructive jaundice. In 5-10% of cases ERCP fails. In these cases an effective alternative is endoscopic ultrasonography-guided biliary drainage (EUS-BD).

New bismuth-containing quadruple therapy in patients infected with Helicobacter pylori: A first Italian experience in clinical practice.

Background: Rising antibiotic resistance requires the evaluation of new and effective therapies.

Aims: To test the efficacy and safety of the new bismuth-containing quadruple therapy in patients infected with Helicobacter pylori.

Material And Methods: Consecutive H.

A Primary-Care Interventional Model on the Diverticular Disease: Searching for the Optimal Therapeutic Schedule.

Introduction: In routine colonoscopy, diverticulosis is the most commonly found feature, but only a minority of these cases show symptoms of diverticular disease.From June 2014 to December 2014, we enrolled prospectively 178 patients affected by symptomatic uncomplicated diverticular disease (Male/Female=0.47, mean age 71.

Does infliximab short infusion have a beneficial impact on the quality of life in patients with inflammatory bowel diseases? A single centre prospective evaluation.

Background & Aims: Infliximab (IFX) is an anti-tumor necrosis factor alpha agent used in inflammatory bowel diseases (IBD) therapy. Usually, it is administered over a 2-hour intravenous infusion. However, shortening the infusion duration to 1 hour has proved to be feasible and safe.
