Rheumatoid arthritis is a serious autoimmune disease that attacks the joints and other body parts. But RA can be tough to diagnose. Symptoms can mimic other illnesses, or they may flare, then fade, only to flare again somewhere else. Lab tests arenât perfectyou can test negative for RA factors and still have it.heumatoid arthritis is a serious autoimmune disease that attacks the joints and other body parts.

People with pyruvate dehydrogenase deficiency usually have neurological problems as well. Most have delayed development of mental abilities and motor skills such as sitting and walking. Other neurological problems can include intellectual disability, seizures, weak muscle tone (hypotonia), poor coordination, and difficulty walking.
(2). The organization of the subunits of the pyruvate dehydrogenase complex, which is located in the mitochondria in eukaryotic organisms, differs from that of gram negative organism. In gram negative organism, the complex is composed of 24 subunits of E2 that form trimers.yruvate dehydrogenase (E1) is responsible for the first two reactions. First it decarboxylates pyruvate with the help of the coenzyme TPP to form hydroxyethyl-TPP. Secondly, the hydroxyethyl group is transferred to dihydrolipoyl transacetylase (E2) through the use of lipoic acid bound to a modified lysine residue.
