The ratio of T and B lymphocytes and DNA content in population enriched by these cells were analysed in the lymph nodes of BALB/c mice with progressively growing sarcomas induced by the MSV Moloney and in untreated mice. T lymphocyte enriched fractions have a higher DNA content in comparison to fractions enriched with B lymphocytes. Sarcoma development promotes a decrease in the relative number of macronucleolar lymphocytes and simultaneous decrease of micronucleolar ones in the lymph nodes, particularly in the regional ones.

Yutangba, situated in Enshi City, Hubei Province, is globally noted for its high selenium (Se) content. Soil invertebrates are essential to the functionality and services of terrestrial ecosystems, yet their community composition in this region remains under-explored. This study utilized environmental DNA metabarcoding to investigate the interrelations among environmental factors, soil invertebrate diversity, and community characteristics concerning soil Se content, pH, and moisture content in the region.

(2n=2x=14, genome SS) is a wild relative of wheat and a donor of useful traits for wheat improvement. Several whole-genome studies compared genic regions of from the section and wheat and found that is most closely related to the wheat B subgenome but is not its direct progenitor. The results showed that a B subgenome ancestor diverged from more than 4 MYA and either has not yet been discovered, or is extinct.

Droplet-based microfluidics is a powerful tool for high-throughput analysis of liquid samples with significant applications in biomedicine and biochemistry. Nevertheless, extracting content-rich information from single picolitre-sized droplets at high throughputs remains challenging due to the weak signals associated with these small volumes. Overcoming this limitation would be transformative for fields that rely on high-throughput screening, enabling broader multiparametric analysis.
