Effects of 30- and 90-Minute Afternoon Nap Opportunities on Field-Test Performance in Female Collegiate Basketball Players

Afternoon napping is used as a recovery strategy in sport, but a scheduled nap opportunity is not equivalent to objectively verified sleep. This study ...

Alzheimer's disease (AD) is the most common neurogenerative disorder without effective treatments. Defects in mitochondrial complex I are thought to contribute to AD pathogenesis. The aim of this study is to explore whether a novel gene therapy transducing yeast complex I gene NDI1 can be used to treat AD with severely reduced complex I function in cell and animal models.

The Chinese tree shrew () has gained prominence as a model organism due to its phylogenetic proximity to primates, offering distinct advantages over traditional rodent models in biomedical research. However, the neuroanatomy of this species remains insufficiently defined, limiting its utility in neurophysiological and neuropathological studies. In this study, immunofluorescence microscopy was employed to comprehensively map the distribution of three calcium-binding proteins, parvalbumin, calbindin D-28k, and calretinin, across the tree shrew cerebrum. Serial brain sections in sagittal, coronal, and horizontal planes from 12 individuals generated a dataset of 3 638 cellular-resolution images. This dataset, accessible via Science Data Bank (https://doi.org/10.57760/sciencedb.23471), provides detailed region- and laminar-selective distributions of calcium-binding proteins valuable for the cyto- and chemoarchitectural characterization of the tree shrew cerebrum. This resource will not only advance our understanding of brain organization and facilitate basic and translational neuroscience research in tree shrews but also enhance comparative and evolutionary analyses across species.

This systematic review and meta-analysis aimed to estimate the effects of daytime napping on athletic performance across multiple domains in team ball sports athletes. Five electronic databases (PubMed, Scopus, Web of Science, Cochrane Library, and SPORTDiscus) were systematically searched from their inception to December 18, 2025, to identify randomized controlled trials (RCTs) investigating the association between daytime napping and objective performance measures compared with a no-nap control condition. Twelve trials encompassing 179 team ball sports athletes met the inclusion criteria. Nap interventions were consistently scheduled in the early afternoon (13:00-15:30), most frequently commencing at 14:00. Following presumed normal nocturnal sleep, napping demonstrated a large positive effect on endurance performance (SMD = 0.96, 95% CI 0.62 to 1.29, p < 0.001) and a moderate improvement in agility (SMD = 0.55, 95% CI 0.01 to 1.09, p = 0.048). A moderate positive trend was also observed for power and strength (SMD = 0.50, 95% CI -0.09 to 1.09), although the 95% confidence intervals crossed zero. Subgroup analyses revealed that the magnitude of these effects was modulated by nap duration, with longer naps (>60 min) yielding the largest improvements in endurance (SMD = 1.38) and power (SMD = 0.84), while moderate naps (31-60 min) similarly conferred substantial benefits. These findings suggest that strategic napping, particularly moderate and long durations, should be considered for integration into training and competition routines for athletes achieving presumed normal nocturnal sleep. However, effects on cognitive and technical performance remain uncertain due to evidence imprecision. Strategic napping protocols should be tailored to specific sport performance demands to optimize physiological recovery and readiness.
