Pickering asphalt-water emulsions stabilized by polystyrene nanoparticles obtained from recycled material
Abstract: In recent years, emulsified asphalt has been found to offer numerous advantages over conventional asphalt. More recently still, emulsified asphalt stabilized with nanoparticles has emerged as an option for the construction field because this substance has many advantages over traditional emulsified asphalt, which is formulated with surfactants that tend to be less stable and more toxic. These new formulations are called Pickering emulsions. They can align with basic sustainability principles. …

Protagonist of Aspirin in Primary Treatment of Cardiovascular Disease: An Overview
Abstract: AbstractAspirin (ASA) is the most used medication on the globe. The benefits of aspirin therapy for the secondary prevention of cardiovascular disease clearly outweigh the risks of bleeding, and low- dose aspirin is uniformly recommended in this condition. While the clinical use of aspirin in secondary cardiovascular disease (CVD) prevention remains undisputed, its role in primary prevention is controversial. Recently, three trials of primary prevention reported neutral net benefit results …
