1. Influencia de compostos carboxilicos e ions metalicos na degradação de neurotransmissores / Influence of carboxylate and metal ions on the degradation of neurotransmitters
Several neurological disorders are associated with improper catechoalmine regulation in the brain. Numerous researches have indicated that metallic ions can induce oxidative stress-dependent neurodegeneration of dopamine, and are responsible for the induction of neurodegenerative diseases. In previous work was verified that some carboxylates diminishes the o

2. Síntese e caracterização de complexos contendo núcleos dimetálicos de rutênio e ligantes dicarboxilatos / Synthesis and characterization of complexes containing dinuclear ruthenium and dicarboxylate ligands
Compostos do tipo [M2(O2CR)4] com ligação múltipla direta entre os centros metálicos apresentam importância do ponto de vista teórico bem como da química aplicada a diversas áreas. Recentemente tem havido um grande interesse voltado, especialmente, para o design de novos materiais construídos com base nestas unidades dimetálicas. O principal objeti

3. Mechanism of silicate binding to the bacterial cell wall in Bacillus subtilis.
To investigate the chemical mechanism of silicate binding to the surface of Bacillus subtilis, we chemically modified cell wall carboxylates to reverse their charge by the addition of an ethylenediamine ligand. For up to 9 weeks, mixtures of Si, Al-Fe-Si, and Al-Fe-Si plus toxic heavy metals were reacted with these cells for comparison with control cells and

4. Asymmetric distribution of charge on the cell wall of Bacillus subtilis.
The cell wall of Bacillus subtilis is capable of binding different kinds of metal ions. The wall-ion complex appears to be dependent on both phosphoryl from teichoic acid and carboxylate from peptidoglycan. In the present study, cationized ferritin (CF) was used as a probe for charge distribution on the wall of B. subtilis 168. Detergent-extracted cell walls

5. pH-dependent interactions of Cd2+ and a carboxylate blocker with the rat C1C-1 chloride channel and its R304E mutant in the Sf-9 insect cell line.
1. Gating of the skeletal muscle chloride channel (ClC-1) is sensitive to extracellular pH. In this study, whole-cell recording of currents from wild-type (WT) ClC-1 and a mutant, R304E, expressed in the Sf-9 insect cell line was used to investigate further the nature of the pH-sensitive residues. 2. Extracellular Cd2+ produced a concentration-dependent bloc

6. Anionic lipid headgroups as a proton-conducting pathway along the surface of membranes: a hypothesis.
Evidence has been gathering from several laboratories that protons in proton-pumping membranes move along or within the bilayer rather than exchange with the bulk phase. These experiments are typically conducted on the natural membrane in vivo or in vitro or on fragments of natural membrane. Anionic lipids are present in all proton-pumping membranes. Model s
