Evolutionary patterns of the SSU rRNA (V4 region) secondary structure in genus (Ciliophora, Spirotrichea): insights into cryptic species and primitive traits.

The genus , a group of ciliated protists, has attracted attention as a model organism due to its widespread distribution and ease of cultivation. This study examines the evolutionary patterns of the SSU rRNA secondary structure within this genus, aiming to elucidate its role in supporting evolutionary relationships and uncovering cryptic species. By predicting the secondary structure of SSU rRNA and applying the CBC (Compensatory Base Change) concept analysis, we examined 69 species of the genus , with 57 SSU rRNA gene sequences retrieved from GenBank and 12 newly sequenced specimens from South Korea.

Protists as mediators of complex microbial and viral associations.

Microbial eukaryotes (aka protists) are known for their important roles in nutrient cycling across different ecosystems. However, the composition and function of protist-associated microbiomes remains largely elusive. Here, we employ cultivation-independent single-cell isolation and genome-resolved metagenomics to provide detailed insights into underexplored microbiomes and viromes of over 100 currently uncultivable ciliates and amoebae isolated from diverse environments.

Innovative approaches to eczema treatment: A review of Fevipiprant and its potential as a new therapeutic agent.

Eczema is also known as atopic dermatitis, which goes on to affect the skin as a chronic inflammatory disease. It is associated with a constant feeling of scratchiness, erthyma and disruption of the natural skin barrier. Treatment provided at present may improve some of the symptoms, for instance use of corticosteroids or immunosuppressive agents, however, there is an overwhelming need for better focused and effective methods of treatment with minimal adverse effects.
