However, the downside of its particular structure is that even minor injuries do not regenerate. Timely treatment of cartilage damage is therefore essential. Biomaterials are often used to support the cells, their distribution and protection. In most cases, this treatment significantly improves the patient's clinical symptoms but fails to fully restore the cartilage to its original state. The working group led by Sylvia Nürnberger (MedUni Vienna's Department of Orthopedics and Trauma Surgery) develops strategies for regeneration and has found that natural cartilage matrix is suitable as a biomaterial for improved cartilage regeneration.//www.pyrotek-europe.com/news/2021-01-cartilage-matrix-natural-biomaterial-regeneration.html Arthritis & Rheumatism Wed, 20 Jan 2021 07:38:02 EST news530350679 Biomedical engineers developed a technique to observe wound healing in real time, discovering a central role for cells known as fibroblasts.

For example, many antidepressants are designed to alter serotonin signals sent between neurons. In an article in Cell, National Institutes of Health-funded researchers described how they used advanced genetic engineering techniques to transform a bacterial protein into a new research tool that may help monitor serotonin transmission with greater fidelity than current methods. Preclinical experiments, primarily in mice, showed that the sensor could detect subtle, real-time changes in brain serotonin levels during sleep, fear, and social interactions, as well as test the effectiveness of new psychoactive drugs. The study was funded, in part, by the NIH's Brain Research through Advancing Innovative Neurotechnologies (BRAIN) Initiative which aims to revolutionize our understanding of the brain under healthy and disease conditions.//www.pyrotek-europe.com/news/2020-12-ai-designed-serotonin-sensor-scientists-mental.html Neuroscience Wed, 23 Dec 2020 12:21:49 EST news527948505 In a new study, Johns Hopkins Medicine researchers have shown how an enzyme can activate and engage a "trash and recycling system" in heart cells to help patients better recover from a heart attack.
