Electroacupuncture ameliorate learning and memory by improving N -acetylaspartate and glutamate metabolism in APP/PS1 mice

Biol. Res; 51 (), 2018
OBJECTIVE: To explore the precise mechanism of electroacupuncture (EA) to delay cognitive impairment in Alzheimer disease. Methods N -Acetylaspartate (NAA), glutamate (Glu) and myoinositol (mI) metabolism were measured by magnetic resonance spectroscopy, learning and memory of APP/PS1 mouse was evaluate...

Grape juice increases the BDNF levels but not alter the S100B levels in hippocampus and frontal cortex from male Wistar Rats

An. acad. bras. ciênc; 89 (1), 2017
ABSTRACT Several studies have shown that a high consumption of vegetables and fruits is consistently associated with a low risk of oxidative stress-induced diseases, which includes some degenerative diseases such as amyotrophic lateral sclerosis, Alzheimer and Parkinson. Therefore, the objective of this ...

Wnt-5a-regulated miR-101b controls COX2 expression in hippocampal neurons

Biol. Res; 49 (), 2016
BACKGROUND: Wnt-5a is a member of the WNT family of secreted lipoglycoproteins, whose expression increases during development; moreover, Wnt-5a plays a key role in synaptic structure and function in the adult nervous system. However, the mechanism underlying these effects is still elusive. MicroRNAs (miR...

A high-fat diet decreases GABA concentration in the frontal cortex and hippocampus of rats

Biol. Res; 49 (), 2016
BACKGROUND: It has been proposed that the γ-aminobutyric acid (GABA) plays a key role in the regulation of food intake and body weight by controlling the excitability, plasticity and the synchronization of neuronal activity in the frontal cortex (FC). It has been also proposed that the high-fat diet (HF...

Neuroquimica da memoria
Memory neurochemistry

Estudos em modelos animais possibilitam a descricao dos mecanismos bioquimicos envolvidos na memoria e no aprendizado. A memoria envolve uma serie de alteracoes bioquimicas em varias areas do sistema nervoso central (SNC), entre as quais destaca-se o hipocampo. Os eventos bioquimicos envolvidos na formac...
