Heme was extracted from fresh pig blood and made into powder in black coffee color. The product contained about 1.2%-1.8% iron and was added into food to raise its iron content.Three experiments were performed on young mice, piglets and anemic children. After feeding this product, their hemoglobin was all raised significantly (P

Magnetic Resonance Imaging(MRI)technology can directly show the changes of brain network and explain the central mechanism of Tai Chi remodeling of brain structure and function.In this paper,we collected the domestic and foreign research on the influence of Tai Chi movement on the brain network by using MRI technology,and combed it from the perspective of brain structure and function changes.The results revealed that Tai Chi may promote memory function,cognitive flexibility,inhibitory control,and working memory capacity by remodeling the structure and function of the medial temporal lobe and prefrontal cortex in older adults,which may be a potential central mechanism for Tai Chi to improve memory and cognitive control in the elderly.However,there are some problems in the current research,such as small sample size,insufficient long-term follow-up,and difficult evaluation of exercise intensity.It is necessary to carry out large-sample and long-term detailed research to further verify the current research results.
