Synthesis, design and integrated in vitro/in silico assessment of novel cyano-amide derivatives

A novel and an efficient synthesis of a series of cyano-amide derivatives 3a-h was achieved via solvent-free reaction of benzylcyanide derivatives 1 with isocyanate derivatives 2 at room temperature. The produced components were structurally characterized by NMR spectroscopy mult...

Knowledge Spillovers Versus Competitive Dynamics: Evidence from Startups and Scaleups in Milan’s Tech Ecosystem

Abstract Moving beyond the traditional focus on geographical proximity, this study investigates the existence and nature of spillover effects within a non-geographical space. The core novelty of the paper is operational and methodological: we exploit text data scraped from corpor...

Corrosion fatigue behavior of hyper-quenched X6CrNiMoCu25-6 steel in synthetic seawater at 70 °C

The aim of this study is to investigate the corrosion fatigue behavior of X6CrNiMoCu25–6 steel in a hyper-quenched state in synthetic seawater at 70°C. Cracking tests were performed on standardized CT10 test specimens in environments representative of the operating conditions of...

Less is more? Evaluating the role of radioiodine therapy in pediatric differentiated thyroid cancer management

Purpose: Differentiated thyroid carcinoma (DTC) is the most common endocrine malignancy in children and adolescents. Pediatric DTC often presents with extensive nodal disease or pulmonary metastases, yet disease-specific survival consistently exceeds 95-98%. This paradox challeng...

Robust hybrid internal model control based smith predictor for MIMO systems with multiple time delays

Internal Model Control based Smith Predictor for MIMO processes with multiple time delays is reported in this paper. The proposed structure combines the advantages of Smith predictor and Internal model control while providing a simplified tuning strategy for the Internal Model Co...

Contribution of a combined approach using refined enterotyping and non-negative matrix factorization (NMF) to the characterization of the gut microbiota in Tunisia, North Africa

Abstract This pilot study aimed to assess the enhanced capabilities of a combined approach using refined enterotyping and non-negative matrix factorization (NMF) for identifying specific microbiota patterns in healthy adults in Tunisia. Shotgun metagenomic sequencing was performe...

The filtration performance of fabrics against particles of viral size: a systematic review

Wearing a mask is part of the comprehensive strategy to suppress transmission of the SARS-CoV-2 virus and respiratory tract infections. Despite available COVID-19 vaccines, wearing a mask has remained one of the simplest and most effective ways. There was, however, little data av...

Realization of unconventional staircase topological Anderson phase transitions

Topological Anderson insulators provide a paradigm for disorder-induced topology, in which the underlying system turns from a trivial to a topological phase. It is widely recognized that the latter disappears at large disorder amplitude. Here, and contrary to the general belief,...

N-Acetylcysteine, Tiron, and Their Combination: In Vitro Antioxidant and Anti-Inflammatory Activities and Their Protective Effect in a Rat Model of Acetic Acid-Induced Ulcerative Colitis

Ulcerative colitis is characterized by inflammation, oxidative stress, and excessive free radical production. This study investigated the antioxidant, anti-inflammatory, and protective effects of N-acetylcysteine (NAC), Tiron, and their fixed-ratio combination in acetic acid-indu...

Effect of Different Metal Doping of ZnO Nanoparticles on Photocatalytic Degradation of Dye Wastewater

Undoped ZnO and metal-doped ZnO (ZnO:M) nanoparticles (NPs), with M [Formula: see text] Ca, V and Al, have been synthesized, with the same metal content ([Formula: see text]%), by the sol–gel method. The M-doping effects on the ZnO NPs properties are studied by a variety of techn...
