Kinetic and structural studies of Mycobacterium tuberculosis dihydroorotate dehydrogenase reveal new insights into class 2 DHODH inhibition
(Biochimica et Biophysica Acta - General Subjects, 2023) [Artigo]Tuberculosis (TB) is a leading cause of death worldwide. TB represents a serious public health threat, and it is characterized by high transmission rates, prevalence in impoverished regions, and high co-infection rates ... -
Out-of-plane deformability and its coupling with electrostatics in biomembranes
(Emerging topics in life sciences, 2023) [Artigo]Cell membranes are quasi-bidimensional soft systems formed by multipoles in an ordered array that can be polarized in an electric field. Consequently, electrostatic potentials emerge inside membranes, and membranes respond ... -
Electrochemical sensor based on epoxy-functionalized BEA nanozeolite and graphene oxide modified glassy carbon electrode for bisphenol E determination
(Journal of Applied Electrochemistry, 2023) [Artigo]An epoxy-functionalized beta type nanozeolite (BEA)/graphene oxide nanocomposite modified glassy carbon electrode (GCE/BEA/APTMS/GA/GO/NF) has been created for the differential pulse voltammetric determination of bisphenol ... -
Self-assembly of dengue virus empty capsid-like particles in solution
(iScience, 2023) [Artigo]Nucleocapsid (NC) assembly is an essential step of the virus replication cycle. It ensures genome protection and transmission among hosts. Flaviviruses are human viruses for which envelope structure is well known, whereas ... -
The influence of pH on the structure and stability of the Grb2 dimer reveals changes in the inter-domain and molecular interaction: Could it be a modulation mechanism?
(Biophysical Chemistry, 2023) [Artigo]Cancer cells present an increased replicative potential as a hallmark. The increased replication leads to a higher intracellular pH. Grb2, an adapter protein, is mainly involved in several types of cancers due to its role ... -
An adsorption agent based on chitosan-zeolite composite: environmental and radioactive liquid waste remediation
(Environmental Science: Advances, 2023) [Artigo]In this article, we present a chitosan-zeolite composite, which was synthesized and used as an adsorbent material for caesium (Cs) removal from aqueous media and real liquid radioactive organic waste (LROW). The compound ... -
Interphase chromosomes of the Aedes aegypti mosquito are liquid crystalline and can sense mechanical cues
(Nature Communications, 2023) [Artigo]We use data-driven physical simulations to study the three-dimensional architecture of the Aedes aegypti genome. Hi-C maps exhibit both a broad diagonal and compartmentalization with telomeres and centromeres clustering ... -
