Effective Colonization by Nontoxigenic Clostridioides difficile REA Strain M3 (NTCD-M3) Spores following Treatment with Either Fidaxomicin or Vancomycin.

Colonization with nontoxigenic Clostridioides difficile strain M3 (NTCD-M3) has been demonstrated in susceptible hamsters and humans when administered after vancomycin treatment. NTCD-M3 has also been shown to decrease risk of recurrent C. difficile infection (CDI) in patients following vancomycin treatment for CDI.

Investigation of 2-Hydroxypropyl-β-Cyclodextrin Treatment in a Neuronal-Like Cell Model of Niemann-Pick Type C Using Quantitative Proteomics.

Niemann-Pick, type C (NPC) is a fatal, neurovisceral lysosomal storage disorder with progressive neurodegeneration and no FDA-approved therapy. Significant efforts have been focused on the development of therapeutic options, and 2-hydroxypropyl-β-cyclodextrin (HP--CD) has emerged as a promising candidate. In cell culture, HP--CD ameliorates cholesterol storage in endo/lysosomes, a hallmark of the disorder.

Lipidomic Analysis Reveals Altered Fatty Acid Metabolism in the Liver of the Symptomatic Niemann-Pick, Type C1 Mouse Model.

Niemann-Pick disease, type C1 (NPC1) is a fatal, autosomal recessive, neurodegenerative disorder caused by mutations in the NPC1 gene. As a result of the genetic defect, there is accumulation of unesterified cholesterol and sphingolipids in the late endosomal/lysosomal system causing both visceral and neurological defects. These manifest clinically as hepatosplenomegaly, liver dysfunction, and neurodegeneration.
