Piracetam reverses haloperidol-induced catalepsy in mice
Results: Th e administration of haloperidol (2 mg/kg, IP) resulted in signifi cant catalepsy. Piracetam (in dosages of 50, 100, and 300 mg/kg) given IP at the time of haloperidol administration reduced the duration of catalepsy by 24.4%, 32.3%, and 48.2%, respectively. Piracetam given as a 30-min pretreatment reduced the duration of catalepsy by 59.5%, 72.3%, and 78.2%, respectively. Vinpocetin...
متن کاملFerroelectricity Induced by Incommensurate Magnetism (Invited)
Ferroelectricity has been found to occur in several insulating systems, such as TbMnO3 and Ni3V2O8 which have more than one phase with incommensurately modulated long-range magnetic order. Here we give a phenomenological model which relates the symmetries of the magnetic structure as obtained from neutron diffraction to the development and orientation of a spontaneous ferroelectric moment induc...
متن کاملVacancy Defects Induced Magnetism in Armchair Graphdiyne Nanoribbon
Spin-polarized electronic and transport properties of Armchair GraphdiyneNanoribbons (A-GDYNR) with single vacancy (SV), two types of configurations fordouble vacancy (DV1, DV2) and multi vacancy (MV) defects are studied by nonequilibriumGreen’s function (NEGF) combined with density functional theory (DFT).The results demonstrate that the A-GDYNR with the SV has the lowe...
متن کاملDefect-induced magnetism: Codoping and a prescription for enhanced magnetism
Recent works have given indication that the defect-induced magnetism in diluted magnetic semiconductors (DMSs), transition metal oxides (TMOs), and related materials is facilitated and enhanced by codoping and the synergistic action among the codopants. In the present work we demonstrate that the proposed defect-induced ferromagnetic coupling (FMC) exhibits the following features: bipartition, ...
متن کاملDefect-induced magnetism in graphene
We study from first principles the magnetism in graphene induced by single carbon atom defects. For two types of defects considered in our study, the hydrogen chemisorption defect and the vacancy defect, the itinerant magnetism due to the defect-induced extended states has been observed. Calculated magnetic moments are equal to 1 B per hydrogen chemisorption defect and 1.12–1.53 B per vacancy d...
