Nav1.7 is considered a promising target for developing next-generation analgesic drugs, given its critical role in human pain pathologies. Although most reported inhibitors with strong vitro activity and high selectivity share the aryl sulfonamide scaffold, they failed to demonstrate marked clinical efficacy. Therefore, exploring new Nav1.7-selective antagonists quite urgent development of drugs. Here, we report highly effective 1H-indole-3-propionamide inhibitor, WN2, identified through an...

OBJECTIVE: To determine the efficacy of anti-LINGO-1 antibody BIIB033 in subjects with a first episode acute optic neuritis (AON). BACKGROUND: The demyelination and axonal injury during AON usually results permanent structural functional visual deficits. Although corticosteroid treatment can accelerate rate spontaneous recovery, no reparative is available to reduce sequelae AON.

Background The indirect antiglobulin test (IAT) and direct (DAT) have been used as common tests for transfusion. Recently, we found that in addition to causing false increases, rheumatoid factor (RF) can also cause decreases immunoassays hepatitis B surface antigen B-type natriuretic peptide. However, it remains unclear whether RF interferes with the IAT DAT. Methods models were produced by mixing IAT-positive plasma RF-positive plasma, then one-step two-step IATs adopted detection.
