Frailty as a mediator between sleep quality and cognitive impairment among the rural older adults: a cross-sectional study.

Background: Cognitive impairment is a common health problem among older adults. Previous studies have proven the association between sleep quality and cognitive impairment, but the specific underlying mechanisms need to be further explored. This study aimed to examine the relationship between sleep quality and cognitive impairment and the mediating effect of frailty in this relationship among the rural older adults.

Neural network-based aeroelastic system identification for predicting flutter of high flexibility wings.

Flutter is an extremely significant academic topic in both aerodynamics and aircraft design. Since flutter can cause multiple types of phenomena including bifurcation, period doubling, and chaos, it becomes one of the most unpredictable instability phenomena. The complexity of modeling aeroelasticity of high flexibility wings will be substantially simplified by investigating the prospect of system identification techniques to forecast flutter velocity.

Perspectives of persons with mild cognitive impairment, caregivers and healthcare professionals on computer-assisted cognitive training: A multi-perspective qualitative study.

Objective: To explore the perspectives and perceptions of persons with mild cognitive impairment (MCI), their caregivers, and healthcare professionals on computerized cognitive training (CCT).

Material And Methods: Utilizing phenomenological research methods, 12 MCI patients, 11 caregivers, and 15 healthcare professionals were recruited. Data were collected through four focus group interviews and six semi-structured in-depth interviews conducted between March 2023 and June 2023.

Impact of 2,4-di-tert-butylphenol on pancreatic lipase activity in emulsions: Multispectral, molecular docking, and in vitro digestion analysis.

2,4-di-tert-butylphenol (2,4-DTBP) is an additive used in food packaging. The inhibitory effects of 2,4-DTBP on pancreatic lipase (PL) were investigated in this study. Kinetic analysis indicated that 2,4-DTBP competitively and reversibly inhibited PL activity.
