Enhanced formic acid oxidation on polycrystalline platinum modified by spontaneous deposition of gold. Fourier transform infrared spectroscopy studies
(Elsevier Science, 2015-08)
Formic acid and adsorbed carbon monoxide electrooxidation on polycrystalline Pt and Au-modified Pt surfaces were studied by cyclic voltammetry, lineal sweep voltammetry and in-situ Fourier transform infrared spectroscopy ...
Eletro-oxidação de metanol e etanol sobre PtAu/C em meio alcalino
(Universidade Estadual Paulista (Unesp), 2016)
Eletro-oxidação de metanol e etanol sobre PtAu/C em meio alcalino
(Universidade Estadual Paulista (Unesp), 2012)
The development of electrocatalysts for the oxidation of methanol and ethanol is very important, because these alcohols may be used in the anode fuel cells which convert chemical energy directly into electrical energy with ...
Investigação de biomarcadores diagnósticos para a doença de Alzheimer no líquido cefalorraquidiano, na saliva e na mucosa oral.
(Universidade Federal de Minas GeraisUFMG, 2012-08-02)
The population is getting older and this is one of the greatest triumphs of humanity and one of our greatest challenges. In Brazil, the number of elderly (65 years old or older) increased from about five million in 1980 ...
Association of Longitudinal Changes in Cerebrospinal Fluid Total Tau and Phosphorylated Tau 181 and Brain Atrophy with Disease Progression in Patients with Alzheimer Disease
(American Medical Association, 2019-12)
The amyloid/tau/neurodegeneration (A/T/N) framework uses cerebrospinal fluid (CSF) levels of total tau (tTau) as a marker of neurodegeneration and CSF levels of phosphorylated tau 181 (pTau181) as a marker of tau tangles. ...
Alzheimer's Disease Biomarker Profile in Cerebrospinal Fluid of Individuals With Immune-Mediated Encephalitis
(American Geriatrics Society, 2016-06)
All of these individuals had rapid onset of dementia,with cognitive fluctuation, neuropsychiatric symptoms, andseizures. The individuals underwent brain magnetic resonance imaging (MRI), CSF analysis, and tumor screening.An ...
Cognitive impairment in late-life bipolar disorder is not associated with Alzheimer's disease pathological signature in the cerebrospinal fluid
(2016-02-01)
Objectives: Cognitive impairment is a common feature of late-life bipolar disorder (BD). Yet, there is limited information on the biological mechanisms associated with this process. It is uncertain whether cognitively ...
Cognitive impairment in remitted late-life depression is not associated with Alzheimer's disease-related CSF biomarkers
(2020-07-01)
Background: Cognitive impairment is a common feature of late-life depression (LLD). Early studies using Alzheimer's disease (AD) biomarkers inferred a biological link between AD pathology and LLD, but recent findings have ...
Comparación Neuropatológica, Neuropsicológica e Imagenológica entre Alzheimer esporádico y la mutación en PS1 E280A
(2011)
En este estudio descriptivo de serie de casos se comparan las características neuropatológicas, neuropsicológicas e imagenológicas de dos grupos de pacientes con enfermedad de Alzheimer (AD); uno esporádico (SAD) y uno ...
