In the current investigation rhizome of Zingiber officinale and leaf Ocimum sanctum were extracted using ethanol-water (70:30) anti-amnesic potential combined extracts was evaluated in experimental model. The extraction yield hydroalcoholic mixture found to be 10.4 % for 17.7 sanctum. Preliminary phytochemical analysis suggested presence alkaloids, saponin glycosides, phenolics, terpenoids, fla...

Background and Aim: In this study, we investigated the effect of immobilization stress during pregnancy on the spatial memory, anxiety-like behavior and brain BDNF level in F1 generation male NMRI mice. Materials and Methods: Twenty female pregnant mice were randomly divided into stress and control groups. The stress group received stress using a restraint cylinder (6 cm ID, 20 cm L) 60 min/da...

The effect of the non-selective 5-HT2C receptor agonist trifluoromethyl-phenylpiperazine (TFMPP, 0.75, 1.5 and 3.0 microg) and the preferential 5-HT2C agonist 6-chloro-2(1-piperazinyl)pyrazine (MK-212, 0.1, 0.3 and 1.0 microg) microinjected into the ventral or dorsal hippocampus was investigated in anxiety measures of rats exposed to the elevated plus-maze test. Ventral hippocampal (VH) microin...

This study examined the effects on cognitive behaviors of giving normal adult gerbils three compounds, normally in the circulation, which interact to increase brain phosphatides, synaptic proteins, dendritic spines, and neurotransmitter release. Animals received supplemental uridine (as its monophosphate, UMP; 0.5%) and choline (0.1%) via the diet, and docosahexaenoic acid (DHA; 300 mg/kg/day) ...

Niemann-Pick Type C1 (NPC1) is an autosomal recessive inherited disorder characterized by accumulation of cholesterol and glycosphingolipids. Previously, we demonstrated that BALB/c-npc1nihNpc1-/- mice treated with miglustat, cyclodextrin and allopregnanolone generally performed better than untreated Npc1-/- animals. Unexpectedly, they also seemed to accomplish motor tests better than their sha...

Background and Objective: Physical activity has long been associated with mental health. Nepeta menthoides is a native Iranian herb recently acknowledged for its anti-depressant properties. This study attempted to determine and compare the effects of swimming exercise and Nepeta menthoides on reserpine-induced depression in rats.Materials and Methods: Male rats (n=80) were assigned to 8 g...

introduction: effective perception of fear signals is crucial for organism survival. when threated, the organism indicates defensive behaviors. methods: elevated plus–maze has high efficiency for measurement of fear behavior and is widly used for fear behavior determination. increase in two parameters percent of openarm entries (%oae) and percent of time spent in the open-arm (%oat) in the elev...

background: atrial fibrillation is a common arrhythmia in patients with rheumatic mitral and other valve diseases who are candidates for valve repair surgeries. conversion of rhythm to sinus has positive effects on quality of life and lower use of medications. the aim of this clinical study was to evaluate the effectiveness of the radiofrequency ablation maze iii procedure in the treatment of a...

INTRODUCTION Caffeine is frequently consumed concurrent to or immediately following ethanol consumption. Identifying how caffeine and ethanol interact to modulate behavior is essential to understanding the co-use of these drugs. The plus-maze discriminative avoidance task (PMDAT) allows within-subject measurement of learning, anxiety, and locomotion. METHODS For training, each mouse was place...

Huntington's disease (HD), a neurodegenerative disorder caused by an expanded CAG repeat in the huntingtin gene, impairs information processing in the striatum, which, as part of the basal ganglia, modulates motor output. Growing evidence suggests that huntingtin interacting protein 14 (HIP14) contributes to HD neuropathology. Here, we recorded local field potentials (LFPs) in the striatum as H...
