Summary: This study found that exercise has anti-inflammatory and antioxidant effects on pulmonary fibrosis induced by paraquat, reducing the infiltration of inflammatory cells and fibrotic lesions. Furthermore, exercise also increased the expression of antioxidative distress proteins, improved the degree of epithelial-mesenchymal transition in alveolar epithelial cells, and ultimately alleviated paraquat-induced pulmonary fibrosis.

Summary: Exercise has been proven to improve cognitive function, and studies on both humans and animals have shown this. Laboratory mice are often used as a model to study the effects of exercise, and running wheels provide a voluntary and stress-free form of exercise for mice. This study aimed to analyze the relationship between the cognitive state of a mouse and its wheel-running behavior. The results showed that high-runner mice exhibited enhanced learning capabilities and ate more compared to the other groups. Interestingly, individual mice had different reactions when introduced to running wheels, suggesting the importance of considering individual differences in voluntary endurance exercise studies.

Summary: Sequence variants modulating gene function or expression affect heritable traits such as neuron count. This study identified candidate genes and sequence variants controlling retinal neuron count using a forward-genetic approach. Analysis of mouse strains revealed three genomic loci on Chromosomes 9, 11, and 19 that contribute to variation in cell number. Two candidate genes, Dtx4 and Dixdc1, were identified as regulators of signaling pathways and their sequence variants were found to modulate gene expression and influence the number of retinal neurons.

Summary: The study developed a convolutional neural network model to accurately assess the running frequency of aged mice. The model achieved a 94% accuracy rate. This research method provides a higher resolution of information for studying the physiological effects of voluntary wheel running activity.

Summary: Anxiety disorders are commonly diagnosed psychological conditions that are often treated with drugs, but these medications can have side effects. Exercise is an effective treatment for anxiety, and it has been found to release extracellular vesicles (EVs) that may help reduce anxiety. Research suggests that exercise-derived EVs may have anti-anxiety effects.

Summary: Cisplatin decreases energy-consuming activities but not energy-procuring activities unless they require a choice between options differing in their cost-benefit ratio. The physical dimension of fatigue is more likely to develop in cisplatin-treated individuals than the motivational dimension of fatigue.

Summary: This article introduces a method that combines radiotelemetry system and running wheels to determine spontaneous cage activity and voluntary exercise levels of individual animals in group-housed rodents. A software tool is developed for fast and reliable data analysis. This method can be used to study the benefits of physical activity and the impact of therapeutic interventions on animal behavior.

Summary: The study found that exercise helps faster recovery from paclitaxel-induced weight loss and deficits in melanocortin signaling, but did not alleviate fatigue or inflammation. Body mass recovery was associated with the wheel running-induced recovery of body composition and associated peripheral circulating hormones.

Summary: This study found that voluntary exercise can prevent the increase in BACE1 activity and maintain memory recall in ovariectomized female mice. This may provide a method of slowing the progression of Alzheimer's disease.

Summary: Recent clinical studies suggest a close association between dry eye and psychiatric disorders. This study investigates the depressive-like behavior in two mouse models of dry eye and the potential benefits of voluntary wheel-running in alleviating depressive states induced by dry eye.

Summary: Chronic restraint stress affects the behavior of mice, specifically their voluntary wheel running but not working for food. This indicates a dissociation between energy demanding and energy procuring activities, possibly due to adaptive response to mitochondrial dysfunction caused by chronic restraint stress.

Summary: Maternal overnutrition increases offspring's susceptibility to metabolic diseases, while maternal exercise can improve glucose metabolism. However, the underlying mechanism of intergenerational effects of maternal exercise on glucose metabolism benefits is not fully understood.

Summary: Exercise can delay aging and have beneficial effects on the musculoskeletal system. High body weight is more protective for muscle and bone health, while exercise can increase muscle size and function, and reduce muscle loss. The combination of exercise and high body weight has the best effect on muscle and bone health.

Summary: PNN is a promising candidate for harnessing neural plasticity, especially in rehabilitation. SCI reduces PNN density in the spinal cord, while activity-based therapies can reverse this decrease and improve functional recovery.
