Single‐cell RNA‐sequencing and spatial transcriptomic analysis reveal a distinct population of APOE− cells yielding pathological lymph node metastasis in papillary thyroid cancer

Clinical and Translational Medicine, Volume 15, Issue 1, January 2025.
We identified a subpopulation of tumor cells with lower expression levels of APOE in both mRNAs and proteins that were highly associated with more advanced stages and metastasis of PTC by integrating single‐cell sequencing and spatial transcriptome assays.

Homotopy Perturbation Method for Investigating Population Dynamics in Oxygen‐Depleted Environments

Discrete Dynamics in Nature and Society, Volume 2025, Issue 1, 2025.
This research will seek to construct a theoretical model to study both the ultraviolet (UV) degradation of hydrogen sulfide (H2S) without oxygen and population dynamics in anoxic environments. Solving some of the issues in biogas energy usage, this paper is interested in modeling H2S photodegradation, simulation of parameters that influence degradation
