A patient complains of a “stabbing pain and a burning sensation” in his left foot. the nurse notices that the foot is a lighter

lyudmila [28]

The answer that best completes the statement above is this: POSTERIOR TIBIAL. Based on the nurse's assessment, stabbing pain and burning sensation is reported as the subjective cue and the skin of the foot is lighter. Given this result, this would clearly mean that the artery in the left foot is being occluded. And the artery present here is the posterior tibial artery. The stabbing pain and burning sensation being felt of the patient is a result of lack of oxygen in the area since the blood can no longer circulate.

A new drug is developed that prevents the demyelinization occurring in the progress of multiple sclerosis. The drug protects the

Aleonysh [2.5K]

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

How are babies made im really cunfuzzeled

jenyasd209 [6]

Answer:

through a process called meiosis

Explanation:

what is meiosis? Meiosis is a type of cell divison that produces haploid sex cells such as eggs and sperm cells.

A human egg and a human sperm cell each have 23 chromosomes. When an egg is joined with or Fertilized  by a sperm cell. a new diploid cell is formed the new cell would have 46 chromosomes (have from each parent.)

After fettilization a new fertilized egg cell forms called a Zygote
