[Purpose] To determine the optimal Tuina rolling manipulation parameters for improving peripheral blood circulation and to observe the duration of these effects. [Participants and Methods] A total of 162 healthy males and 20 males with coronary heart disease were recruited, with a mean age of 29.5 ± 6.4 years. The change in blood flow was used as the observation index, and the best combination of parameters was selected using a cyclic orthogonal experiment. We observed changes in rolling manipulation across different time periods and groups. [Results] There were significant interactions between pressure, frequency and duration in the rolling manipulation. The combination mode of 4 kg, 120 repetitions/min and 10 min is the most effective to improve the average blood flow increase rate of popliteal artery. At 15 minutes after manipulation, different degrees of significant increase were observed, but 20 minutes after manipulation, the average blood flow rate returned to the premanipulation level. There was no difference in blood flow rate between healthy males and coronary heart disease patients. [Conclusion] An effective dynamic model of rolling manipulation was constructed. These results contradicted the idea that more pressure and longer continuous manipulation led to stronger effects. The effect of rolling manipulation on improving peripheral circulation can be maintained for 20 minutes.

Genome editing based on the homology-directed repair (HDR) pathway enables scar-free and precise genetic manipulations. However, the low frequency of HDR hinders its application in plant genome editing. In this study, we engineered the fusion of Cas9 and a viral replication protein (Rep) as a molecular bridge to tether donor DNA in vivo, which enhances the efficiency of targeted gene insertion via the HDR pathway.

Many biological disciplines rely upon the transformation of host cells with heterologous DNA to edit, engineer, or examine biological phenotypes. Transformation of model cell strains () under model conditions (electroporation of circular supercoiled plasmid DNA; typically pUC19) can achieve >10 transformants/μg DNA. Yet outside of these conditions, e.

Cancer poses a substantial threat and a serious challenge to public human health, driving the promotion of sophisticated technologies for cancer therapy. While conventional chemotherapy has bottlenecks such as low delivery efficiency, strong toxic side effects, and tumor enrichment barriers, magnetic micro/nanorobots (MNRs) emerge as promising therapeutic candidates that provide alternative strategies for cancer therapy. MNR is a kind of human-made machine that is micro- or nanosized, is reasonably designed, and performs command tasks through self-actuated or externally controlled propulsion mechanisms, which can be potentially applied in cancer theranostics.

Precisely capturing and manipulating microscale objects, such as individual cells and microorganisms, is fundamental to advancements in biomedical research and microrobotics. Photoactuators based on optical fibers serving as flexible, unobstructed waveguides are well-suited for these operations, particularly in confined locations where free-space illumination is impractical. However, integrating optical fibers with microscale actuators poses significant challenges due to size mismatch, resulting in slow responses inadequate for handling motile micro-objects.

Light-driven wireless actuators provide obvious advantages for remote control. However, traditional double-layer actuators are restricted to the thin film deformation mode when undertaking complex tasks. Here, an actuator is proposed that employs thermal strain and local photothermal effects induced by low boiling point liquids to generate asymmetry along the fiber axis, thereby causing elastic deformation of the fiber.
