Association of 30-s Sit-to-Stand Power Test Outcome With Body Balance in Physically Active Older Adults.

Amount of serial sitting and standing movements has been employed in clinical and research settings to assess legs' muscular strength. In this cross-sectional study, we aimed to test the correlation between the 30-s sit-to-stand power test (30STSp) outcome and body balance in older adults. We evaluated physically active male and female (n = 51) individuals with an age range of 60-80 years (M = 69.

Chronic stress triggers impairments of the redox status of salivary glands associated with different histological responses in rats.

Stress occurs as a reaction to mental and emotional pressure, anxiety, or scarring. Chronic stress is defined as constant submission to these moments. It can affect several body systems, increase blood pressure, and weaken immunity, thereby interfering with physiological health processes.

Antioxidant and Antimicrobial Properties of Probiotics: Insights from In Vitro Assays.

Probiotics are microorganisms that provide health benefits at adequate doses and exhibit notable antioxidant and antimicrobial activities. These properties play crucial roles in combating chronic diseases linked to oxidative stress and antimicrobial resistance. This review aimed to summarize the antioxidant and antimicrobial properties of probiotics determined in in vitro studies and discuss mechanistic actions and analysis methods.

Robust Method for Property Prediction via Artificial Neural Networks: Incorporating Key Structural Features for Carbon Dioxide-Ionic Liquid Mixtures.

This study addresses a critical gap in the existing literature on carbon dioxide and ionic liquid (IL) mixtures, where fragmented and incomplete data, particularly for flow properties, hinder practical applications. Therefore, this work aimed to establish a robust and efficient method for predicting the density of the CO-IL mixtures across diverse operating conditions and IL families using novel validation techniques. Both linear and symbolic regression models provided relevant insights but failed to accurately capture the IL-CO interactions in a mixture that determine the molar volume of CO at infinite dilution when solubilized by a given IL.

Knowledge and attitudes of nursing students regarding the sexuality of older adults: a quasi-experimental study.

Objectives: to compare the knowledge and attitudes of nursing students regarding sexual behavior and sexually transmitted infections (STIs) in older adults before and after an educational intervention.

Methods: this quasi-experimental study involved a convenience sample of 45 nursing students from a public university, conducted in three stages: pre-intervention, intervention, and post-intervention. A questionnaire was used to assess sociodemographic characteristics, academic training, and knowledge and attitudes on the topic.
