Objectives: To develop radiomics models based on multi-sequence MRI from two centers for the preoperative prediction of the WHO/ISUP grade of Clear Cell Renal Cell Carcinoma (ccRCC).

Methods: This retrospective study included 334 ccRCC patients from two centers. Significant clinical factors were identified through univariate and multivariate analyses.

Article Synopsis
  • Long-term exposure to aluminum increases the risk of mild cognitive impairment (MCI), a condition that can affect memory and cognitive function.
  • A study involving 52 individuals with over 10 years of occupational aluminum exposure found a negative correlation between cognitive scores (measured by the MoCA) and plasma aluminum levels.
  • The research revealed differences in white matter integrity and functional connectivity in specific brain pathways among those with MCI compared to healthy controls, suggesting potential neural mechanisms linking aluminum exposure to cognitive decline.

Present anion exchange membranes are generally constructed by simple and positively charged polymers with insufficient organic solvent resistance, and exhibit a low selectivity in the separation of anions. Here, dissolving poly(paraphenylene terephthalamide) nanofibers into small nanofibers and performing a reaction with quaternary ammonium groups in the one-dimensional small nanofibers, high-performance anion exchange membranes were successfully fabricated. By increasing the 2,3-epoxypropyl trimethylammonium chloride content, the synthesized amide nanofiber quaternary ammonium membranes (ANF#QA) exhibited a higher anion exchange capacity (as high as 1.
