Analytical and clinical performance of thyroglobulin autoantibody assays in thyroid cancer follow-up.

abstract：:The pathogenesis of cobalamin (Cbl)-deficient (Cbl-D) neuropathy and the role of normal prions (PrPcs) in myelin maintenance are both subjects of debate. We have demonstrated that Cbl deficiency damages myelin by increasing tumor necrosis factor (TNF)-α, and decreasing epidermal growth factor (EGF) levels in the rat c...
