Article Synopsis
  • The study aimed to investigate the prevalence of autoimmune encephalitis and coexisting viral infections in children with acute encephalitic syndrome (AES).
  • It found that out of 867 children examined, 4.2% were diagnosed with autoimmune encephalitis, primarily associated with anti-NMDAR antibodies, while 47.1% had evidence of viral infections, particularly HSV.
  • The researchers concluded that autoimmune encephalitis may be more common than previously reported and emphasized the importance of early diagnosis and treatment for better outcomes in affected children.

This viewpoint advocates for significant reforms in the disability certification guidelines for mental illnesses in India. Currently, two years duration of illness is required before certification, which delays essential support. The proposed model emphasizes assessing the functional impact of conditions, aligns with global standards, and suggests regular reassessments to improve accessibility and inclusivity in mental health services.

Neutrophils are the most abundant leukocytes in humans and play an important early role in the innate immune response against microorganisms. Neutrophil phagosomes contain high concentrations of antibacterial enzymes, including myeloperoxidase (MPO) and the neutrophil serine proteases (NSPs). These antibacterial enzymes can also be released extracellularly upon degranulation or as a component of neutrophil extracellular traps (NETs).

Enzymes are indispensable in several applications including biosensing and degradation of pollutants and in the drug industry. However, adverse conditions restrict enzymes' utility in biocatalysis due to their inherent limitations. Metal-organic frameworks (MOFs), with their robust structure, offer an innovative avenue for enzyme immobilization, enhancing their resilience against harsh solvents and temperatures.

During the COVID-19 pandemic, our findings highlight changes in AML management strategies in India. There was a decrease in overall patient registrations, particularly at large referral centers, while smaller centers saw an increase, reflecting a shift towards more localized care. This shift was accompanied by a rise in the use of hypomethylating agents (HMAs).

A new bidentate Schiff base ligand (CHClN), condensation product of ethylene diamine and 4-chloro N-phenyl formamide, and its metal complexes [M(CHClN)(OAc)] (where M = Mn(II) and Zn(II)) were synthesized and characterized using various analytical and spectral techniques, including high-resolution mass spectrometry (HRMS), elemental analysis, ultraviolet-visible (UV-vis), Fourier-transform infrared (FTIR) spectroscopy, AAS, molar conductance, H NMR, and powder XRD. All the compounds were non-electrolytes and nanocrystalline. The synthesized compounds were assessed for antioxidant potential by DPPH radical scavenging and FRAP assay, with BHT serving as the positive control.
