This study examines the energy expenditure and physiological responses associated with short-term quadrupedal locomotion compared to bipedal walking in humans. It aims to support evolutionary theory and explore quadrupedal locomotion's potential for enhancing fitness and health. In a randomized crossover design, 12 participants performed quadrupedal and bipedal walking on a treadmill at identical speeds.

However, the prevalence of sedentary behavior has increased, with only a minority of individuals meeting the recommended physical activity guidelines. This study aimed to investigate whether habitual leg shaking, a behavior traditionally considered unfavorable, could serve as an effective strategy to improve energy metabolism.

NANOG is known to be a core transcription factor in the maintenance of stem cell specific features or stemness. To evaluate whether NANOG was involved in the immunomodulation effects of MSCs, MSCs' immunomodulation capacity on lymphocyte activation and proliferation before or after endogenous NANOG interference was investigated.

Previous studies have suggested that mesenchymal stem cells (MSCs) may ameliorate fibrogenesis and represent a promising strategy for cell therapy. However, the underlying mechanisms are not fully understood.

Despite significant progress, most therapeutic approaches fail to eliminate all tumor cells. The remaining tumor cells often result in recurrence and metastasis.
