Understanding the molecular, cellular, and physiological components of neurodegenerative diseases (NDs) is paramount for developing accurate diagnostics and efficacious therapies. However, the complexity of ND pathology and the limitations associated with conventional analytical methods undermine research. Fortunately, microfluidic technology can facilitate discoveries through improved biomarker quantification, brain organoid culture, and small animal model manipulation.

Pervasive Games for Sexual Health Promotion: Scoping Literature Review.

JMIR Serious Games

January 2025

Department of Interactive Visualization and Virtual Reality, Faculty of Engineering, University of Talca, Talca, Chile.

Background: Serious games play a fundamental role in promoting safe sexual behaviors. This medium has great potential for promoting healthy behaviors that prevent potential risk factors, such as sexually transmitted infections, and promote adherence to sexual health treatments, such as antiretroviral therapy. The ubiquity of mobile devices enhances access to such tools, increasing the effectiveness of video games as agents of change.

Background: Although bariatric and metabolic surgical methods, including duodenal-jejunal bypass (DJB), were shown to improve metabolic dysfunction-associated steatotic liver disease (MASLD) in clinical trials and experimental rodent models, their underlying mechanisms remain unclear. The present study therefore evaluated the therapeutic effects and mechanisms of action of DJB in rats with MASLD.

Methods: Rats with MASLD were randomly assigned to undergo DJB or sham surgery.

Evaluation of radiation therapy on grafted and non-grafted defects: an experimental rat model.

J Appl Oral Sci

January 2025

Universidade Federal de Uberlândia, Faculdade de Odontologia, Departamento de Periodontia e Implantodontia, Uberlândia, Brasil.

Objective: This study aimed to assess the effects of a single-dose radiation therapy (15 Gy) on grafted and non-grafted defects, bone microarchitecture, and collagen maturity.

Methodology: Bone defects were surgically created in rat femurs. The right femur defect was filled with blood clot (group "Clot") and the left femur defect by deproteinized bovine bone mineral graft (group "Xenograft").

Purpose: To evaluate intravenous meropenem and intraperitoneal 10% aqueous extract of Schinus terebinthifolius (aroeira) in elderly rats after autogenous fecal peritonitis.

Methods: Thirty 18-month-old Wistar rats underwent peritonitis with 4 mL/kg of autogenous fecal solution. They were stratified into groups: control without treatment; study I, treated with meropenem (40 mg/kg); and study II, treated with meropenem at the same dose and intraperitoneal 10% aqueous extract of aroeira.
