Objective: This study aimed to examine the relationship between physical performance and mild cognitive impairment (MCI) in Chinese older adults.
Methods: The sample comprised 956 relatively healthy and aged ≥65 years old Chinese community-dwelling participants (mean age, 72.56 ± 5.43 years; 56.8% female), which did not include those with dementia, severe cognitive impairment, mental illness etc. The Mini-Mental State Examination (MMSE) and the Instrumental Activities of Daily Living (IADL) scale were used for the initial classification of patients with MCI. Physical performance was measured via hand grip, Timed Up and Go Test (TUGT), and 4-m walking speed.
Results: The physical performance (grip strength, TUGT, and 4-m walking speed) correlated with MCI. The grip strength [odds ratio (OR) = 0.96, 95% confidence interval (CI) = 0.93-0.99] and 4-m walking speed (OR = 0.25, 95% CI = 0.10-0.64) correlated negatively with MCI, while TUGT (OR = 1.08, 95% CI = 1.03-1.13) and MCI correlated positively.
Conclusion: The physical performance (grip strength, TUGT, and 4-m walking speed) correlated with MCI. Further analysis showed that the grip strength was associated with overall cognition, time orientation, recall, and language, while TUGT and 4-m walking speed were associated with overall cognition and various cognitive domains, except recall.

Background: Myotonic dystrophy type 1 (DM1) is a multisystemic, CTG repeat expansion disorder characterized by a slow, progressive decline in skeletal muscle function. A biomarker correlating RNA mis-splicing, the core pathogenic disease mechanism, and muscle performance is crucial for assessing response to disease-modifying interventions. We evaluated the Myotonic Dystrophy Splice Index (SI), a composite RNA splicing biomarker incorporating 22 disease-specific events, as a potential biomarker of DM1 muscle weakness.

Parkinson's disease (PD) stands as the sec most prevalent incapacitating neurodegenerative disorder characterized by deterioration of dopamine-producing neurons in the substantia nigra. Coenzyme Q10 (CoQ10) has garnered attention as a potential antioxidant, anti-inflammatory agent and enhancer of mitochondrial complex-I activity. This study aimed to examine and compare the effectiveness of liposomal and non-encapsulated CoQ10 in rotenone induced-PD mouse model over a 21-day treatment duration.

Metal halides are widely applied in solid-state lighting (SSL), optoelectronic devices, information encryption, and near-infrared (NIR) detection due to their superior photoelectric properties and tunable emission. However, single-component phosphors that can be efficiently excited by light-emitting diode (LED) chips and cover both the visible (VIS) and NIR emission regions are still very rare. To address this issue, (TPA)ZnBr:Sn/Mn (TPA = [(CHCHCH)N]) phosphors were synthesized by using the solvent evaporation method.

Real-time monitoring of the dynamics of cytosolic RNA-protein condensates, termed stress granules (SGs), is vital for understanding their biological roles in stress response and related disease treatment but is challenging due to the lack of simple and accurate methods. Compared with protein visualization that requires complex transfection procedures, direct RNA labeling offers an ideal alternative for tracking SG dynamics in living cells. Here, we propose a novel molecular design strategy to construct a near-infrared RNA-specific fluorescent probe () for tracking SGs in living cells.

Sarcopenia is an age-related muscle atrophy syndrome characterized by the loss of muscle strength and mass. Although many agents have been used to treat sarcopenia, there are no successful treatments to date. In this study, we identified Danshensu sodium salt (DSS) as a substantial suppressive agent of muscle atrophy.
