The association between frailty and falls among individuals aged 60 years and older residing in community settings and experiencing hip fractures in China: a cross-sectional study.

Objectives: Previous studies have established a correlation between frailty and an increased risk of falls among middle-aged and elderly individuals within community settings. The frailty status of hospitalized and community-dwelling adults aged 60 or older with hip fractures is poorly investigated. This study aims to examine the relationship between frailty status and falls in China among community-dwelling and hospitalized individuals with hip fractures aged 60 and older.

The mediating effect of 24-h time-use behaviors on the relationship between depression and mortality: A compositional mediation analysis for survival outcomes.

Background: A compositional mediation model of survival outcomes was established to explore whether 24-h time-use behaviors mediate the relationship between depression and mortality.

Methods: 4137 adults from the National Health and Nutrition Examination Survey (NHANES 2005-2006) were followed up to 2019. Cox proportional hazards regression model was used to estimate the total effect of depression on mortality.

Highly Facile Strategy for Detecting DO in HO by Porphyrin-Based Luminescent Probes.

Owing to their almost similarities in size, shape, and chemical reactivity, effectively distinguishing deuteroxide (DO) in water (HO) remains an ongoing challenge, and the examples of a DO probe are still quite scarce. Herein, since HO can decrease the lifetime of a singlet oxygen as a vital intermediate and an H/D exchange in the luminescence process of porphyrins, we systematically investigated the enhanced ultraviolet-visible (UV-vis), photoluminescence (PL), and electrochemiluminescence (ECL) of water-soluble tetrakis(carboxphenyl)porphyrin (TCPP) in DO. The findings showed that these luminescent properties had been greatly enhanced with the increase of the DO fraction in water.

Correlations of hair level with salivary level in cortisol and cortisone.

Aims: Contrary findings exist on the consistency between hair cortisol and salivary cortisol in assessing the basal activity of the hypothalamic-pituitary-adrenal (HPA) axis. The mismatches in temporal characteristic and the indices of hair and salivary cortisol might be potential reasons for the inconsistency. The aim of this study was to investigate the consistency between hair and salivary levels in cortisol and cortisone by directly examining the correlation between hair level and salivary level with different temporal characteristics (acute, short-term and long-term levels) and reflecting different HPA functions (basal level and reactivity level) in the well-matched time span.

[Effects of prednisone on renal FAK and Pyk2 expressions in rats with adriamycin- induced nephritis].

Objective: To investigate the effects of prednisone on the expressions of FAK and Pyk2 in the kidneys of rats with adriamycin-induced nephritis.

Methods: Thirty SD rats were randomized into normal control group, adriamycin-induced nephritic model group, and prednisone treatment group (n=10). Prednisone was administered at 10 mg/kg once daily in nephritic rats starting since the 7th day after adriamycin injection.
