MOG IgG antibody positivity from laboratory to clinical practice: A real world experience.

Background And Objectives: Myelin oligodendrocyte glycoprotein (MOG) associated disease (MOGAD) is an antibody-mediated inflammatory demyelinating disorder of the CNS with varied presentations like optic neuritis (ON), transverse myelitis, and cortical encephalitis. This study aims to highlight the significance of low MOG IgG antibody positivity and its diagnostic implications in a real-world cohort.

Methods: In this retrospective observational study, serum and CSF from suspected MOGAD cases were tested at a tertiary healthcare centre's Neuroimmunology Laboratory.

Clinical Manifestations of Anti-GABA-B Receptor Encephalitis: A Case Series.

Anti γ aminobutyric acid B(GABA B) receptor encephalitis is a rare form of autoimmune encephalitis. Our aim is to study the clinical characteristics and treatment outcomes of anti GABA B receptor encephalitis. This is a retrospective case series from the Neuroimmunology laboratory of Amrita Institute of Medical Sciences, Kochi, Kerala, India from 2016 to 2021.

Making target sites in large structured RNAs accessible to RNA-cleaving DNAzymes through hybridization with synthetic DNA oligonucleotides.

The 10-23 DNAzyme is one of the most active DNA-based enzymes, and in theory, can be designed to target any purine-pyrimidine junction within an RNA sequence for cleavage. However, purine-pyrimidine junctions within a large, structured RNA (lsRNA) molecule of biological origin are not always accessible to 10-23, negating its general utility as an RNA-cutting molecular scissor. Herein, we report a generalizable strategy that allows 10-23 to access any purine-pyrimidine junction within an lsRNA.
