Objectives: This study investigates education differences in levels and change in sense of control and hopelessness among older adults.
Method: We used data from the Health and Retirement Study, an ongoing biennial survey of a nationally representative sample of older Americans, to examine education differences in sense of control (e.g., mastery and perceived constraints) and hopelessness. Our sample included 8,495 adults aged 52 and older who were interviewed in 2006/2008 and 2010/2012. We assessed separate models for change in sense of control and hopelessness, accounting for recent changes in social circumstances and health status.
Results: Low mastery, perceived constraints, and hopelessness were highest among individuals with less than a high school education. Over a 4-year period, this group experienced the greatest declines in psychosocial functioning, as indicated by greater increases in low mastery, perceived constraints, and hopelessness. Education differences existed net of recent negative experiences, specifically the loss of intimate social relationships and social support and increases in disease and disability.
Discussion: These findings highlight the importance of education for sense of control and hopelessness in older adulthood and demonstrate the cumulative advantage of higher levels of education for psychosocial functioning.

Introduction: The present study aimed at evaluating the systemic profile and network connectivity of immune mediators during acute chikungunya fever (CHIKF) according to days of symptoms onset and ageing.
Methods: A total of 161 volunteers (76 CHIKF patients and 85 non-infected healthy controls) were enrolled.
Results And Discussion: Data demonstrated that a massive and polyfunctional storm of serum immune mediators was observed in CHIKF.

Controlling the light emitted by individual molecules is instrumental to a number of advanced nanotechnologies ranging from super-resolution bioimaging and molecular sensing to quantum nanophotonics. Molecular emission can be tailored by modifying the local photonic environment, for example, by precisely placing a single molecule inside a plasmonic nanocavity with the help of DNA origami. Here, using this scalable approach, we show that commercial fluorophores may experience giant Purcell factors and Lamb shifts, reaching values on par with those recently reported in scanning tip experiments.

Fiber-based strain sensors, as wearable integrated devices, have shown substantial promise in health monitoring. However, current sensors suffer from limited tunability in sensing performance, constraining their adaptability to diverse human motions. Drawing inspiration from the structure of the spiranthes sinensis, this study introduces a unique textile wrapping technique to coil flexible silver (Ag) yarn around the surface of multifilament elastic polyurethane (PU), thereby constructing a helical structure fiber-based strain sensor.

Purpose: The purpose of the study was to explore the facilitators and barriers of health behaviors in patients with type 2 diabetes (T2D), providing a reference for the development of health behavior interventions programs.
Methods: A qualitative descriptive research design was adopted, and interviews were conducted with 25 patients with T2D. The interview guide was developed based on the health action process approach theory.
