The impact of halogen substitution quantities on the fluorescence intensity ratio of lanthanide Schiff base complexes.

The signal intensity ratio (SIR) is a crucial factor in advancing probe technology due to its direct impact on sensitivity and precision, particularly in applications such as medical imaging, environmental monitoring, and food safety testing. However, the development of high-SIR probes is challenged by complexities in fabrication, cost, and mechanical stability. In this study, we address these limitations by investigating the role of halogen atom substitutions in modulating the intermolecular binding energy and aggregation behavior of Ce-Salen Schiff base complexes.

Sources of perceived social support and cognitive function among older adults: a longitudinal study in rural China.

Background: Studies have shown the positive impact of perceived social support on cognitive function among older adults in rural areas. However, existing studies often overlook the impact of different support sources. This study aimed to explore the relationship between the diverse sources of perceived social support and cognitive function.

Longitudinal validation of cognitive reserve proxy measures: a cohort study in a rural Chinese community.

Background: While evidence supports cognitive reserve (CR) in preserving cognitive function, longitudinal validation of CR proxies, including later-life factors, remains scarce. This study aims to validate CR's stability over time and its relation to cognitive function in rural Chinese older adults.

Methods: Within the project on the health status of rural older adults (HSRO), the survey included baseline assessment (2019) and follow-up assessment (2022).

A bidirectional relationship between cognitive reserve and cognition among older adults in a rural Chinese community: a cross-lagged design.

Background: The concept of cognitive reserve (CR) plays a crucial role in understanding cognitive aging and resilience. Accumulating evidence revealed the influence of CR proxy on cognitive function, but it remains unknown whether a reverse association or reciprocal effect exists.

Objective: The aim of this study is to observe the bidirectional relationship between cognitive reserve proxies and cognitive function among older adults in rural Chinese communities, providing a better understanding of the underlying mechanisms and potential moderating factors involved.
