INVESTIGAÇÃO DO FENÔMENO DE ISOMERIA: CONCEPÇÕES PRÉVIAS DOS ESTUDANTES DO ENSINO MÉDIO E EVOLUÇÃO CONCEITUAL

Ensaio Pesquisa em Educação em Ciências
As dificuldades conceituais que alunos apresentam sobre o tema "isomerismo" são atribuídas a problemas básicos, como a compreensão de teorias estruturais, ligações químicas e representações de fórmulas estruturais.

Mitochondria and Neuromast Tagging With Fluorescent Gallium‐Triapine Analogues: In Cellulo MP FLIM and Zebrafish Live Imaging

Advanced Science, EarlyView.
Fluorescent BODIPY‐conjugated thiosemicarbazone ligands and their Ga(III), In(III), and Fe(III) complexes, inspired by Triapine, are developed as theranostic agents. Multiphoton FLIM and confocal microscopy in cancer cells and zebrafish reveal real‐time uptake, mitochondrial localisation, and whilst spectroscopic assays indicated preserved complex ...

A novel DNAH11 variant segregating in a sibship with heterotaxy and implications for genetic counseling

Molecular Genetics & Genomic Medicine, 2020
Background Isomerism or heterotaxy syndrome is the loss of normal asymmetry of the internal thoraco‐abdominal organs in the left‐right axis and is associated with cardiovascular malformations.

Selective Inhibition of Integrin β3 Topology Provides a Safer Antithrombotic Strategy

Advanced Science, EarlyView.
Current integrin αIIbβ3 inhibitors effectively reduce thrombosis but also increase bleeding risk. During thrombosis, high shear blood flow can directly activate the integrin αIIbβ3 via a distinct topological change in the β3 transmembrane domain, independent of hemostatic platelet signaling.

A Chirality‐Converted Bacteriolytic Dodecapeptide Regulates Vibrio‐Induced Polymicrobial Infection and Ameliorates Invasion‐Associated Gut Microbiota Disequilibrium

Advanced Science, EarlyView.
Multidrug‐resistant Vibrio infections are rising rapidly and threaten coastal populations worldwide. This study introduces D‐zp37, a chirality‐engineered antimicrobial peptide with exceptional potency against resistant Vibrio species. D‐zp37 kills planktonic cells, blocks mixed‐species biofilms, disrupts essential bacterial stress responses, and shows ...
