Mental Fatigue and Sports Performance of Athletes: Theoretical Explanation, Influencing Factors, and Intervention Methods.

Mental fatigue is an important factor affecting athletes' performance. Explaining the effects of mental fatigue on sports performance from a theoretical point of view can help us deeply understand the interconnection between mental fatigue and sports performance and conduct effective interventions based on this. Combining the relevant literature in China and abroad reveals that the current academic theories on the mechanism of sports fatigue include motivational control theory, underload theory, neural waste disposal hypothesis, and resource depletion theory.

Adipose Mesenchymal Stem Cell-Derived Exosomes as Nanocarriers for Treating Musculoskeletal Disorders.

Musculoskeletal disorders are a series of diseases involving bone, muscle, cartilage, and tendon, mainly caused by chronic strain, degenerative changes, and structural damage due to trauma. The disorders limit the function of patients due to pain and significantly reduce their quality of life. In recent years, adipose-derived mesenchymal stem cells have been extensively applied in regeneration medicine research due to their particular abilities of self-renewal, differentiation, and targeted homing and are more easily accessed compared with other sources.

Mesenchymal stem cell-derived extracellular vesicles: A promising therapeutic strategy in diabetic osteoporosis.

Diabetic osteoporosis (DOP) is a serious complication of diabetes mellitus. It is urgent to explore efficient clinical treatment strategies for DOP. It has been found that mesenchymal stem cell-derived extracellular vesicles (MSC-EVs), as an emerging cell-free therapy, show great potential in DOP treatment.

Exercise alleviates cognitive decline of natural aging rats by upregulating Notch-mediated autophagy signaling.

Notch signaling, a classical signaling pathway of neurogenesis, is downregulated during the aging and age-related neurodegenerative diseases. Exercise has been proposed as an effective lifestyle intervention for delaying cognitive decline. However, it remains unclear whether exercise intervention could alleviate cognitive decline by modulating neurogenesis in naturally aging rats.

An empirical study on smart city construction to enhance residents' participation in physical activity.

Smart city construction, as a new model of urban development, has become a crucial means to encourage residents' participation in physical exercise. However, there is still a lack of systematic exploration regarding the mechanisms by which smart city construction specifically affects residents' engagement in physical activity. This paper analyzes the impact of smart city construction on residents' participation in physical activity using a Difference-in-Differences (DID) model, based on data from the 2010 to 2020 China Family Panel Studies (CFPS).

Application of visual feedback and AR-enhanced wheelchair skill training.

Purpose: Manual wheelchair users with spinal cord injury (SCI) face challenges in wheelchair skill training (WSTr) due to the complexity of learning advanced skills and limited access to rehabilitation services. This review aims to summarize existing WSTr methods for individuals with SCI/disabilities and propose the use of Augmented Reality (AR)-enhanced Immediate Visual Feedback (ARe-IVF) learning modules for wheelie and curbing skill training.

Methods: The proposed ARe-IVF learning modules will incorporate AR-enhanced visual feedback, allowing users to visualize spatial and temporal aspects of wheelchair skills and assess their performance through computer vision technology.

Global, regional, and national burden and trends of Low back pain in middle-aged adults: analysis of GBD 1990-2021 with projections to 2050.

Objective: This study aims to systematically evaluate the burden of low back pain(LBP) in the middle-aged population across global regions and between genders, assess the major risk factors and their impacts, and project the burden to 2050, providing a scientific basis for global preventive actions.

Oriental covalent immobilization of N-glycan binding protein via N-terminal selective modification.

Lectin affinity chromatography is one of powerful tools for the study of protein glycosylation. Different lectin proteins can recognize different structures of monosaccharides or oligosaccharide units, allowing for the selective separation of glycopeptides or glycoproteins containing different polysaccharide structures. However, the N-glycans were only partially captured by most of common lectins, reducing the coverage rate of identifying N-glycoconjugates.

Excellent properties of NaF and NaBr induced DNA/gold nanoparticle conjugation system: Better stability, shorter modified time, and higher loading capacity.

The functionalization of gold nanoparticle (AuNP) is the key procedure for the biochemical and biomedical application. The conventional salt-aging method requires the stepwise additions of NaCl and excessive thiolated DNA, mainly due to the poor tolerance of the DNA/AuNP mixture toward NaCl. Herein, we found that NaF is capable of improving the stability for the modification of AuNP with different bases of DNA sequences (poly A/T/C/G), and allows for adding up with a high concentration of 200 mM at one time, which greatly reduces the total modification time to 0.
