In Huntington's disease (HD) mutant HTT is ubiquitously expressed yet the striatum undergoes profound early degeneration. Cell culture studies suggest that a striatal-enriched protein, Rhes, may account for this vulnerability. We investigated the therapeutic potential of silencing Rhes in vivo using inhibitory RNAs (miRhes). While Rhes suppression was tolerated in wildtype mice, it failed to im...

The Wattakaka volubilis ethanolic extract (WVEE), Wattakaka volubilis sapogenin mixture (WVSM) and drevogenins (DVG) isolated from Wattakaka volubilis (Linn.f) Stapf. were evaluated for neuropharmacological activities using spontaneous motor activity, rotarod performance, motor performance evolution and muscle relaxant test models in mice. Sapogenins seemed to be responsible for neuropharmacolo...

Studies of Quantum Dots biodistribution have shown that these nanoparticles accumulate in various organs, including brain parenchyma, possibly causing functional alterations. To investigate its potential neurotoxicity, we administered QDs to young mice and studied their behaviour during the following weeks. Spontaneous locomotor behaviour in the home cage was not significantly altered in treate...

We studied the effects of sildenafil, a selective inhibitor of PDE5, on the development and the expression of tolerance to diazepam (DZ)-induced motor impairment and sedation in mice. DZ-induced motor incoordination was assessed by the rotarod and chimney tests, and DZ-induced sedation was examined using a photocell apparatus. Sildenafil treatment enhanced the development of tolerance to the mo...

Fluoroacetate has been widely used to inhibit glia metabolism in vivo. It has yet to be shown what the effects of chronic intrathecal infusion of fluoroacetate on nociceptive behavioral testing are. The effects of chronic infusion of fluoroacetate (5 nmoles/h) for 2 weeks were examined in normal rats. Chronic intrathecal fluoroacetate did not alter mechanical threshold (von Frey filaments), res...

REFERENCES METHODS D-264 treatment partially rescued the loss of dopaminergic neurons in SN, inhibited the activation of microglia, and improve the impairment of behaviour caused by MPTP and lactacystin in pole and rotarod tests (data not shown here). The neuroprotective effects of D-264 shown in the present study may partly due to the upregulation of both BDNF and GDNF and the restoration of p...

Abstract Repeated sub-concussive impact (e.g . soccer ball heading), a significantly lighter form of mild traumatic brain injury, is increasingly suggested to cumulatively alter structure and compromise neurobehavioural function in the long-term. However, underlying mechanisms whereby repeated long-term sub-concussion induces cerebral structural changes are currently unknown. Here, we utilised ...

Objective(s): The present study aims at examining the motor coordination performance, serum and cerebellar estrogen, as well as ERβ levels, of ovariectomized rats (as menopausal model) following regular exercise. Materials and Methods:Ten female Sprague Dawley ratsaged 12 weeks old were randomly divided into two groups; all of which underwent ovariectomy. The first group was treated with regula...

Introduction: In this study the antidepressant effect of a new morpholino betalactam composition, 1-(3- morpholinopropyl)-4-(naphthalene-2-yl)-3-phenoxyazetidin-2-one (EB9) administered at three doses, was investigated in an animal model of depression. The CNS stimulant, muscle coordination and toxic effects of this compound were also tested. Methods: Morpholino betalactam at 10, 15 and 20 ...
