As India’s first ISO-Certified stem cell research centre, Plexus offers the most advanced stem cell therapy to manage multiple sclerosis. We use autologous mesenchymal stem cells (MSCs) to reboot the immune system and halt disease progression. Advantages of stem cell therapy for multiple sclerosis include: Slowing or halting the progression of the disease Reducing inflammation and damage to nerve cells Promoting the repair and regeneration of damaged myelin Improvement in symptoms and quality of life for some patients

Copy Link : gooread.fileunlimited.club/pw24/0444013318 | Download Neuroanatomy Text and Atlas Android Using a combined functional and regional approach to neuroanatomy, this book explores how parts of the nervous system work together to regulate body systems and produce behavior. It thoroughly covers the sensory, motor, and integrative systems of the brain and presents an overview of the function in relation to structure and the locations of major pathways and neuronal integrative regions. The illustration program features brain views produced by MRI and PET imaging technology, 2-color line illustrations, and myelin-stained sections. The text also features an 80-page atlas of key views of the surface anatomy of the central nervous system and a set of photographs of myelin-stained sections through the CNS in 3-dimensional anatomical planes. Features: * Approaches neuroanatomy from both functional and regional perspectives -- provides und
