Summary: This study investigated the effects of combining eccentric exercise and green tea supplementation on NRF2 activity. The results showed that neither eccentric exercise alone nor in combination with green tea supplementation significantly increased NRF2 activity in peripheral blood mononuclear cells.

Summary: The purpose of this study was to compare the efficacy of tai ji quan and strength training in preventing falls in older, postmenopausal women after chemotherapy. The study found no significant difference in the incidence of falls between the tai ji quan, strength training, and stretching control groups after 6 months of training. However, there was a significant reduction in fall-related injuries within the tai ji quan group during the first 6 months.

Summary: This meta-analysis and trial sequential analysis evaluated the effect and safety of Tai Chi on bone health in postmenopausal women. The results suggest that Tai Chi may improve bone mineral density in the lumbar spine, femoral neck, and trochanter. However, there was no significant difference in the BMD of Ward's triangle. Further research is needed to determine the effects of Tai Chi on bone turnover markers and calcaneus quantitative ultrasound. Practicing Tai Chi for more than 6 months may yield greater benefits.

Summary: This study aimed to investigate the effects of Tai Chi exercise on working memory capacity and emotional regulation ability among college students. The results showed that after 12 weeks of Tai Chi training, there were significant improvements in visual memory capacity and emotion regulation ability in the Tai Chi group.

Summary: In this study, a robot tutor was developed to investigate the feasibility of robot-mediated exercise for older adults, many of whom failed to meet exercise requirements due to a shortage of trainers. Twenty older adults participated, experiencing a 30-min robot-led Tai Chi exercise. The study demonstrated the initial feasibility of robot-led Tai Chi exercise and found that participants were interested in using a robot tutor in the community.

Summary: This study aims to characterize the effect of prune supplementation on the gut microbiome of postmenopausal women. The results show that prune consumption leads to a decrease in gut microbiome diversity, and different doses of prunes have different effects on the gut microbiome. In addition, prune consumption may enrich beneficial bacterial taxa and correlate with urinary phenolic metabolites and inflammatory markers. These findings suggest that prunes may exert health effects by modulating the gut microbiome.

Summary: This study reports a facile and green strategy of fabricating catkin-like CuAg nanocomposites using tea-polyphenols as the reduction agent. The nanocomposites exhibit a catkin-like special morphology as characterized by physical characterizations. The electrochemical detection hydrogen peroxide (H2O2) results demonstrate the good sensitivity, stability, and anti-interference of the catkin-like CuAg nanocomposites, which can detect H2O2 without any additional mediator or enzyme.

Summary: Tea polyphenols, as active ingredients in tea, have excellent physicochemical properties and bioactivities, making them versatile in material synthesis. Tea polyphenol-derived materials are environmentally friendly, biocompatible and retain potent bioactivities such as antioxidant, antibacterial and anti-cancer properties.

Summary: Cognitive training combined with Tai Chi has positive effects on delaying mild cognitive impairment (MCI) progression to dementia. Prolonged mixed training further delays decline in global cognition and memory. Functional magnetic resonance imaging shows increased regional activity in both cognitive training and Tai Chi group.

Summary: Oat milk tea can curdle when mixed with tea, affecting consumer acceptability. This study investigated the stability and polyphenol bioaccessibility of oat milk tea model systems. The addition of green tea extract influenced stability, with higher fat content resulting in greater stability. Tea polyphenols were stable in oral and stomach digestion stages but degraded in the small intestine stage. The bioaccessibility of tea polyphenols was higher in high-fat oat milk tea models, especially at low green tea extract concentrations.

Summary: This systematic review found that supervised Tai Chi exercises for 8-12 weeks, three times a week, 40-60 minutes each time, could improve fatigue and sleep quality in cancer survivors. However, further confirmation in larger trials is needed, and more research is required to evaluate the effects of Tai Chi on other cancer-related outcomes.

Summary: The study found that tai chi has moderate effects for improving proactive balance and static steady-state balance, and small effects for improving dynamic steady-state balance and balance test batteries in adults over 60 years of age. The practice frequency could predict the effects of tai chi on static steady-state balance, and the 24-form simplified Yang style tai chi was identified as the most optimal program for improving balance in older adults.

Summary: Green tea and its polyphenols have potential in treating skin disorders, especially due to their antioxidant and anti-inflammatory properties. However, clinical evidence only supports the use of oral green tea preparations for protecting the skin from damage caused by ultraviolet radiation. Further research is needed to clarify their efficacy in treating other skin conditions.

Summary: Green tea can influence gut microbiota by either stimulating the growth of specific species or hindering the development of detrimental ones, benefiting health through beneficial bacteria or microbial bioactive metabolites. The inter-relation between green tea and gut microbiota is crucial for many health promoting effects of green tea, with the ability to correct microbial dysbiosis in conditions like obesity or cancer. Tea compounds influence the growth of bacterial species involved in inflammatory processes, potentially impacting the development of chronic diseases.
