Ascorbic acid and resveratrol improve the structural integrity of the extracellular matrix and enhance follicular survival in cultured bovine ovarian tissue.

This study aimed to investigate the changes induced by the culture system and the effect of ascorbic acid and resveratrol on collagen fibers, stromal cells, follicle growth and survival, as well as antioxidant enzyme activity in cultured bovine ovarian tissues. In experiment 1, bovine ovarian fragments were cultured in α-minimum essential medium (α-MEM) for 6 days. Before and after culturing, the fragments were fixed and processed to assess follicular morphology and diameters, stromal cell survival, collagen fibers, and glycosaminoglycans (GAGs).

Safety and effectiveness of pulsed field ablation for pulmonary vein isolation in atrial fibrillation patients: One-year single center experience.

Introduction And Objectives: Pulmonary vein (PV) isolation is one of the cornerstones of rhythm-control therapy for symptomatic atrial fibrillation (AF) patients. Pulsed field ablation (PFA) is a novel ablation modality that involves the application of electrical pulses causing cellular death, and it has preferential tissue specificity. In this study, we aimed to share a one-year single center experience of AF ablation with PFA.

Nursing team proxemic mapping in the hemotherapy space.

Objective: To analyze the influence of proxemic factors on communication and care provided by nursing professionals during transfusion in hemotherapy.

Method: A descriptive, exploratory and qualitative study with 25 nursing professionals from a hospital specializing in onco-hematological diseases in Rio de Janeiro, based on a systematized script, individual records of proxemic factors described by Edward Hall and recorded situational interviews. The analysis considered data thematic content and used the SketchUp 3D Modeling Software Review program to visually demonstrate the behavioral mapping of the interaction of nursing professionals with patients during care.

The interaction between third molars and surrounding periapical tissues in mandibular stress distribution during high-impact trauma: a finite element study.

Background: The presence of mandibular third molars has been associated with the risk of mandibular fractures, highlighting the need for comprehensive studies considering the interaction with other mandibular structures. This study investigates how mandibular third molars and neighboring tissues can influence the structural fragility of the mandible using finite element analysis.

Material And Methods: A finite element analysis study following the guidelines proposed by RIFEM 1.

Non-Intrusive Monitoring of Vital Signs in the Lower Limbs Using Optical Sensors.

Invisible health monitoring is currently a topic of global interest within the scientific community. Sensorization of everyday objects can provide valuable health information without requiring any changes in people's routines. In this work, a feasibility study of photoplethysmography (PPG) acquisition in the lower limbs for continuous and real-time monitoring of the vital signs, including heart rate (HR) and respiratory rate (RR), is presented.
