This is because they use sophisticated digital circuits and computers for signal processing to stimulate muscles, which uses a lot of energy and has poor biocompatibility.īy using a stretchable, low-power organic nanowire neurormorphic device that mimics the structure and functionality of real nerve fibres, the research team was able to control the movement of mice’s legs solely with artificial nerves, eliminating the need for a complicated and large external computer. These conventional approaches, however, have drawbacks that make them unsuitable for patients to use on a long-term basis in their daily lives. This involves applying electrical stimulation to muscles that are no longer arbitrary controlled in neuropathy patients in order to trigger muscle contraction, resulting in functionally effective motions in the biological body while being constrained in a particular space. Despite the dramatic advances in medicine and biology, the medical problem of nerve injury, which has existed since the dawn of humanity, has remained a mystery to science, and there doesn’t appear to be any clear solution in the near future.ĭamaged nerves have been treated in a variety of ways, including surgical procedures and drugs, but it is still nearly difficult to restore damaged or degraded nerve functioning.įunctional Electrical Stimulation (FES), a technique used often in clinical practise for the rehabilitation of patients with neurological impairment, uses computer-controlled signals.

The traumatic account of a celebrity’s spinal cord injury occasionally makes the news. Additionally, some or all of their body functions are permanently lost due to poor bio-signaling because once nerves are injured, they are difficult to rebuild. The nerves are crucial for life activities and also have a substantial impact on quality of life. The nerves are easily harmed by a variety of factors, including physical injury, genetic factors, secondary problems, and ageing. The outcome was published in the prestigious international journal “Nature Biomedical Engineering.” Zhenan Bao (Department of Chemical Engineering, Stanford University, US).

The combination of at least two assays is required to ensure reliable antioxidant activity estimates, especially for early grain-filling stages.

The inconsistencies among the measurements are largely dependent on the developmental stage of the corn kernel. The levels of antioxidants measured by 2,2-diphenyl-1-picrylhydrazyl, ferric reducing antioxidant power, and chemiluminescence showed significant positive correlations with the levels measured by the other assays (r = 0.761–0.893 p 0.699 p < 0.05). The aim of this study is to verify compatibility of the antioxidant activity assays by comparing five different assays in daily kernel samples of the fresh purple waxy corn during grain filling. Promotion of its use requires an appropriate assay to determine antioxidant activity. 1 ISSN: 2468-0834 Subject: 2,2-diphenyl-1-picrylhydrazyl, Zea mays, anthocyanins, antioxidant activity, antioxidants, chemiluminescence, filling period, polyphenols, seeds, waxy corn Abstract: Purple waxy corn is a good source of antioxidant compounds such as anthocyanins and polyphenols.
