(John Wiley and Sons Inc., 2015)© 2015 Wiley Periodicals, Inc. Chronic stress promotes cognitive impairment and dendritic spine loss in hippocampal neurons. In this animal model of depression, spine loss probably involves a weakening of the interaction ...
-
(2002)The exact mechanism of cell death in neurodegenerative diseases remains obscure, although there is evidence that their pathogenesis may involve the formation of free radicals originating from the oxidative metabolism of ...
-
(PERGAMON-ELSEVIER SCIENCE LTD, 2004-02)The purpose of this study was to evaluate the contribution of DT-diaphorase inhibition to in vivo neurodegenerative effects of dopamine (DA) oxidation to the corresponding o-quinones. The neurotoxicity to nigrostriatal DA ...

Copper neurotoxicity in rat substantia Nigra and striatum is dependent on DT-diaphorase inhibition (2008)The dependence of copper neurotoxicity on DT-diaphorase inhibition was suggested from results obtained from a cell line derived from substantia nigra. Therefore, the aim of this study was to evaluate whether CuSO4 neurotoxicity ...

(1983)The influence of luteinizing hormone releasing hormone (LHRH) on the behavioral effects induced by several doses of D-amphetamine (0.25, 0.5, 1.0 and 2.0 mg/kg IP) was studied. A dose response relation was previously ...
-
(1989)The changes in the acquisition of conditioned avoidance responses (CARs) and the performance of some spontaneous behaviors were examined across the estrous cycle of female rats. CARs were facilitated during diestrus, ...
-
(2002)Intracerebral manganese administration together with the DT-diaphorase inhibitor dicoumarol (Mn3+ 40 nmol+-dicoumarol 2 nmol; in 4 μl) into the left medial forebrain bundle (MFB) produced a behavioural pattern characterised ...
-
(1997)The present investigation was designed to explore the influence of estrous cycle phase, ovariectomy, and estradiol replacement on the behavioral effects of the 5-HT2 receptor antagonist, ketanserin. The parameters under ...
-
(1983)Pretraining subcutaneous administration of a high dose of LHRH (100 μg/kg) to intact rats impaired acquisition of a conditioned avoidance response (CAR) in a two way shuttle box. Acquisition of a CAR was also decreased ...
