Answer:
Multiple sclerosis (MS) is the most common demyelinating and an autoimmune disease of the central nervous system characterized by immune-mediated myelin and axonal damage, and chronic axonal loss attributable to the absence of myelin sheaths. T cell subsets (Th1, Th2, Th17, CD8+, NKT, CD4+CD25+ T regulatory cells) and B cells are involved in this disorder, thus new MS therapies seek damage prevention by resetting multiple components of the immune system. The currently approved therapies are immunoregulatory and reduce the number and rate of lesion formation but are only partially effective. This review summarizes current understanding of the processes at issue: myelination, demyelination and remyelination—with emphasis upon myelin composition/architecture and oligodendrocyte maturation and differentiation. The translational options target oligodendrocyte protection and myelin repair in animal models and assess their relevance in human. Remyelination may be enhanced by signals that promote myelin formation and repair. The crucial question of why remyelination fails is approached is several ways by examining the role in remyelination of available MS medications and avenues being actively pursued to promote remyelination including: (i) cytokine-based immune-intervention (targeting calpain inhibition), (ii) antigen-based immunomodulation (targeting glycolipid-reactive iNKT cells and sphingoid mediated inflammation) and (iii) recombinant monoclonal antibodies-induced remyelination.Keywords: calpain, central nervous system, demyelination, fingolimod, glycolipids, lipids, multiple sclerosis, myelin, myelination, NKT cells, oligodendrocytes, remyelination, T cells

Answer:
Calisthenics, as a bodyweight resistance training is generally considered to be an anaerobic exercise due to the short intensity intervals.Mar
Answer:
A respiration rate under 12 or over 25 breaths per minute while resting is considered abnormal.
Explanation:
A person's respiratory rate is the number of breaths you take per minute. The normal respiration rate for an adult at rest is 12 to 20 breaths per minute.
Answer 1: The skin and the Liver are easy to repair using stem cells.
Explanation:
Method of stem cells to heal liver disorders has been demonstrated useful in most of the situations. Scientific research shows the use of stem cells in the therapy and remedy of several disorders like Liver Cirrhosis, End Stage Liver Failure, hereditary liver disorder and including the Liver tumor. The stem cells hold the capacity to regenerate and reproduce by them or stem cells hold particular properties of renewing themselves. Because of their expertise stem cells can modify into any tissue sort, they have enormous potential in several infection treatments and traumatic damages.
Answer 2: Apical meristem and the lateral.The heart, brain, bone marrow and the Lungs in adults are difficult to repair using stem cells.
Explanation:
There are two kinds of stem cells: embryonic stem cells and adult stem cells. Adults also have stem cells in the heart, brain, bone marrow, lungs, and other organs. They are our built-in replacement tools, restoring cells infected by infection, trauma and everyday erosion, and cut. Adult stem cells are extremely difficult for specialists to operate because they are extra challenging to derive and culture than their immature complements.
