In this work, the (TiO) cluster is proposed to adsorb the methylene blue (BM) dye; thus, the quantum parameters to explain the adsorption process are calculated by means of density functional theory calculations. Eight possible configurations are obtained and labeled from M1 to M8. According to the adsorption energy values, they reveal physisorption for at least two cases, and for the rest of the systems, they exhibit chemisorption.

Article Synopsis
  • The SARS-CoV-2 pandemic in Africa has varied significantly across countries, and its overall impact remains unclear.
  • An analysis of 8,746 genomes from 33 African countries indicated that most outbreaks originated from Europe before international travel restrictions took effect.
  • As the pandemic continued, increased movement and local transmission led to the emergence of several variants within Africa, emphasizing the need for a strong pandemic response on the continent to prevent becoming a source of new variants.

Article Synopsis
  • DDX3X is a human RNA helicase essential for various cellular functions, comprising N- and C-terminal domains that influence its interaction with RNA and nucleotides.
  • Research on a DDX3X variant lacking 80 C-terminal residues showed it cannot bind to blunt-ended double-helix RNA, indicating that the N-terminal domain plays a critical role in substrate selection.
  • Compared to the wild-type DDX3X, the C-terminal truncated version exhibits stricter nucleotide specificity, hydrolyzing fewer nucleotide types under certain conditions.
