Construction of tissue-engineered nerves is a novel solution for repairing peripheral nerve defects. The sciatic nerve is the largest peripheral nerve in the body and is known to have a relatively constant anatomical position, sufficient diameter to be easily exposed and operated upon with good repeatability, satisfactory local blood circulation, and is difficult to infect. Owing to these advantages, rat models of sciatic nerve defects are commonly used to study nerve regeneration and repair.展开更多

Several factors pose a challenge for neural regeneration following spinal cord injury. First, glial scars and cavities, which form after spinal cord injury, hinder axonal growth and result in degenerative necrosis of the nerve fibers. Second.展开更多

However, the self-repair effects are minimal because of a limited absolute number, as well as the local microenvironment, post-transplantation. A combined treatment utilizing stem cell transplantation and gone therapy can exert a dual effect involving stem cells and neurotrophic factors. The adenovirus carrier is展开更多

Microglia cells are phagocytic cells present in the retina. In the retina of glaucoma rat models, microglia cells become activated, which suggests a role for microglia in the pathogenesis of optic nerve injury in glaucoma patients. The retinal ganglion cell is the only cell that can produce action potential in the retina,展开更多

The non-linear two-point boundary value problem (TPBVP) (Bratu’s equation, Troesch’s problems) occurs engineering and science, including the modeling of chemical reactions diffusion processes and heat transfer. An analytical expression pertaining to the concentration of substrate is obtained using Homotopy perturbation method for all values of parameters. These approximate analytical results were found to be in good agreement with the simulation results.展开更多

However, the source of Schwann cells is limited and amplification remains difficult. Studies have shown that mesenchymal stem cells, an alternative cell type, can be used for transplantation treatment of peripheral nerve defects.
