A prospective, multi-centric study on the prevalence of dengue, zika and chikungunya in asymptomatic blood donors from different geographical regions of Brazil.

Background And Objectives: Arboviruses outbreaks are increasing in their frequency, geographical area and extension. Brazil is one of the most affected countries in the world, due to its tropical weather and favourable mosquito proliferation conditions. During outbreaks, the safety of the blood supply is a concern, in spite of the low number of transfusion-transmitted cases with clinical impact.

Biomechanical evaluation of stability after mandibular sagittal split osteotomy for advancement by Obwegeser-Dal Pont and Puricelli techniques using three-dimensional finite elements.

Background: The surgical treatment for mandibular repositioning using a bilateral sagittal split osteotomy (BSSO) favours the development of techniques that result in adequate repair and stability. In Puricelli's mandibular sagittal split osteotomy (PMSSO) proposal, the vertical lateral cut osteotomy is located in the interradicular space between the lower first molar and second premolar.

Objectives: This in silico study aimed to investigate the mechanical stability of PMSSO and compare it with the classical Obwegeser-Dal Pont technique for mandibular advancement.

Quantum Simulations and Experimental Insights into Glyphosate Adsorption Using Graphene-Based Nanomaterials.

The increasing global demand for food and agrarian development brings to light a dual issue concerning the use of substances that are crucial for increasing productivity yet can be harmful to human health and the environment when misused. Herein, we combine insights from high-level quantum simulations and experimental findings to elucidate the fundamental physicochemical mechanisms behind developing graphene-based nanomaterials for the adsorption of emerging contaminants, with a specific focus on pesticide glyphosate (GLY). We conducted a comprehensive theoretical and experimental investigation of graphene-based supports as promising candidates for detecting, sensing, capturing, and removing GLY applications.

Core-softened colloid under extreme geometrical confinement.

Geometrical constraints offer a promising strategy for assembling colloidal crystal structures that are not typically observed in bulk or under 2D conditions. Core-softened colloids, in particular, have emerged as versatile chemical building blocks with applications across various scientific and technological areas. In this study, we investigate the behavior of a core-softened model confined between two parallel walls.
