      Acidithiobacillus species are fundamental players in biofilm formation by acidophile bioleaching communities. It has been previously reported that Acidithiobacillus ferrooxidans possesses a functional quorum sensing mediated ...
    • Urrutia Vargas, Pamela Joselyn; Bórquez, Daniel A.; Núñez González, Marco Tulio (MDPI, 2021)
      Iron accumulation and neuroinflammation are pathological conditions found in several neurodegenerative diseases, including Alzheimer's disease (AD) and Parkinson's disease (PD). Iron and inflammation are intertwined in a ...
    • Medina González, Exequiel Antonio; Latham, Danielle R.; Sanabria, Hugo (Elsevier, 2021)
      Evidence regarding protein structure and function manifest the imperative role that dynamics play in proteins, underlining reconsideration of the unanimated sequence-to-structure-to-function paradigm. Structural dynamics ...
    • Maulén, C.; Castillo, S.; Kostic, M.; Pinto, M. (Hindawi, 2021)
      In this paper, we analyze the existence and uniqueness of remotely almost periodic solutions for systems of ordinary differential equations. The existence and uniqueness of remotely almost periodic solutions are achieved ...
