CYB5R3 the subsequent disease manifestation have been described. The disease manifests as the accumulation of oxidized Fe+3 in humans. Type I recessive congenital methemoglobinemia (RCM) is characterized by a deficiency of the soluble isoform and manifests as the cyanosis of skin and mucous membranes. In type II, the defect affects both isoforms and thus affects more general tissues such as red blood cells, leukocytes, and all body tissues. This type is associated with mental deficiency and other neurologic symptoms, which may be because the cytochrome b5 system plays a crucial role in the desaturation of fatty acids in the body. One
Regeneration in humans four weeks later. Research has also been conducted into the engineering of heart valves. Tissue-engineered heart valves derived from human cells have been created in vitro and transplanted into a non-human primate model. These showed a promising amount of cellular repopulation even after eight weeks, and succeeded in outperforming currently used artificial valves. Chronic obstructive pulmonary disease (COPD) is one of the most widespread health threats today. It affects 329 million people worldwide, which makes up nearly 5% of the global population. Having killed over 3 million people in 2012, COPD was the third greatest cause of death. Worse still
