Unveiling the self-assembly process of gellan-chitosan complexes through a combination of atomistic simulations and experiments.

Polyelectrolyte complexes (PECs), formed via the self-assembly of oppositely charged polysaccharides, are highly valued for their biocompatibility, biodegradability, and hydrophilicity, offering significant potential for biotechnological applications. However, the complex nature and lack of insight at a molecular level into polyelectrolytes conformation and aggregation often hinders the possibility of achieving an optimal control of PEC systems, limiting their practical applications. To address this problem, an in-depth investigation of PECs microscopic structural organization is required.

Advanced label-free electrochemical immunosensor for a minimally invasive detection of proteins in paintings.

In recent decades, scientific methodologies applied in theCultural Heritage field have been growing, due to their pivotal role in guiding informed decisions concerning conservation strategies and daily maintenance. To achieve this goal, minimally/non-invasive quantitative and qualitative analyses are needed. However, the non-invasive and selective identification of proteinaceous binders and coatings in artworks represent an open issue in Cultural Heritage science.

Shaping the Future: Proposed Bills to Regulate New and Emerging Tobacco and Nicotine Products in Latin America and the Caribbean Amidst Public Health Concerns and Industry Interests.

Introduction: To examine legislative efforts to regulate new and emerging tobacco and nicotine products (NETNPs) in Latin America and the Caribbean (LAC) between 2017 and 2022.

Aims And Methods: Analysis of online national legislation databases to track NETNP bills using standard snowball search methods.

Results: Bills were identified in 15 out of the 33 LAC countries, accounting for a total of 91 bills targeting NETNPs.

Tobacco industry strategies to influence the regulation of new and emerging tobacco and nicotine products in Latin America and the Caribbean.

Objective: To document tobacco industry strategies to influence regulation of new and emerging tobacco and nicotine products (NETNPs) in Latin America and the Caribbean.

Methods: We analyzed industry websites, advocacy reports, news media and government documents related to NETNPs, focusing on electronic cigarettes and heated tobacco products. We also conducted a survey of leading health advocates.

Investigation into the Influence of the Process Parameters on the Stability of a Poly(Vinyl)-Alcohol-Based Coating System.

Most tablets put on the market are coated with polymers soluble in water. The Opadry II 85 series from Colorcon Inc., is a family of PVA-based products marketed since the 1990s.
