Mice received a single intracerebroventricular injection of Aβ<jats:sub>25–35</jats:sub> (3 nmol/3 μl/per site) and a daily oral administration of PEBT (1 mg/kg, for 10 days). PEBT significantly improved Aβ‐induced learning deficits on the training session in the Morris water maze. At the probe trial session, PEBT significantly decreased the escape latency and increased the number of crossings in the platform local compared with the Aβ‐treated group. PEBT significantly improved Aβ‐induced memory impairment in the step‐down inhibitory avoidance task. General locomotor activity was similar in all groups. This study showed that PEBT ameliorated the impairments of spatial and nonspatial long‐term memory evaluated on Morris water maze and step‐down inhibitory avoidance tasks, respectively. The results suggest that PEBT could be considered a candidate for the prevention of memory deficits such as those observed in Alzheimer's disease. © 2013 Wiley Periodicals, Inc.</jats:p>","journal":"Journal of Neuroscience Research","year":2013,"id":620777,"datarank":0.38474240361923057,"base_score":2.5649493574615367,"endowment":2.5649493574615367,"self_citation_contribution":0.38474240361923057,"citation_network_contribution":0.0,"self_endowment_contribution":0.38474240361923057,"citer_contribution":0.0,"corpus_percentile":null,"corpus_rank":null,"citation_count":12,"citer_count":0,"citers_with_citation_signal":0,"citers_with_endowment":0,"datacite_reuse_total":0,"is_dataset":false,"is_dataset_confidence":null,"is_data_producer":false,"deposit_databanks":null,"is_oa":false,"file_count":0,"downloads":0,"has_version_chain":false,"published_date":null,"fair_score":null,"fair_percentile":null,"algorithm_id":"datarank_citation_only_1hop_v6","ranking_scope":"data_only","authors":[{"id":1096586,"name":"Marcel Henrique Marcondes Sari","orcid":"0000-0002-9913-9306","position":1,"is_corresponding":false},{"id":1223021,"name":"Simone Pinton","orcid":"0000-0001-6630-7329","position":2,"is_corresponding":false},{"id":1298907,"name":"Cristiane Luchese","orcid":"0000-0001-6001-0532","position":3,"is_corresponding":false},{"id":1602655,"name":"José Sebastião Santos Neto","orcid":null,"position":4,"is_corresponding":false},{"id":1602656,"name":"Cristina Wayne Nogueira","orcid":null,"position":5,"is_corresponding":false},{"id":1602654,"name":"Ana Cristina Guerra Souza","orcid":null,"position":0,"is_corresponding":false}],"reference_count":0,"raw_metadata":{"has_enrichment":true,"resolved":true,"title":"2‐Phenylethynyl‐butyltellurium attenuates amyloid‐β peptide(25–35)‐induced learning and memory impairments in mice","abstract":"<jats:p>Our previous study demonstrated that 2‐phenylethynyl‐butyltellurium (PEBT), an organotellurium compound, enhances memory in mice.
