Gamma-aminobutyric acid (GABA) is an important inhibitory transmitter in central nervous system and is involved in pathophysiology of epilepsy. Pentylenete-trazole (PTZ), a convulsant agent, partly acts via anion channel of GABAA receptor. Ivermectin, an antiparasitic agent and a GABAA agonist, has anticonvulsant effect in animal seizure models. Cholestasis increases ...

background: there is unprecedented increase in the processing and packaging of many plant materials into food supplements, herbal medicine, skincare and cosmetic products for human needs. baphia nitida is used for topical skincare products. toluene, a toxic aromatic solvent, is increasingly being used in the production of these skincare and cosmetic products in many industries. this study asses...

Focusing on a highly dispersed 5 wt % Pt/Al2O3 catalyst for industrial hydrogenation and dehydrogenation reactions, we employ inelastic neutron scattering (INS) spectroscopy to obtain the vibrational fingerprint of hydrogenous species formed under different H2 equilibrium pressure temperature. The INS profiles are interpreted basis systematic DFT simulations 26 PtxHy/?-Al2O3 models, indicating ...

Interface engineering is an effective and feasible method to regulate the magnetic anisotropy of films by altering interfacial states between films. Using technique pulsed laser deposition, we prepared La 0.67 Sr 0.33 MnO 3 (LSMO) /SrCoO 2.5 (LSMO/SCO) on (110)-oriented 0.3 0.7 Al 0.65 Ta 0.35 O substrates. By covering SCO film above LSMO film, transformed easy magnetization axis from [001] [ <...

Crystal structure, magnetic and thermal physical properties of EuPd 2 Sn 4 stannide are reported on. From the susceptibility measurements, a divalent state Eu rare earth element is determined together with an antiferromagnetic (AFM) order at 11 K. By applying field, behavior variation reveals complex structure. Above critical field B c , ferromagnetic (FM)-like character starts to prevail. AFM ...

Not your usual superconductor Most superconductors have only one superconducting phase. Khim et al . measured the magnetic susceptibility of heavy fermion material CeRh 2 As to reveal presence two distinct phases, which emerges from other when an external field is applied (see Perspective by Pourret and Knebel). The researchers ascribe unusual properties its crystal structure, globally centrosy...

Background & Aim:Albizia chevalieri Harms (Mimosaceae) is widely used in traditional medicine to treat various kinds of diseases such as epilepsy, diabetes mellitus, hemorrhoids, asthma, leprosy and gonorrhoea. The effectiveness of its leaf extract in the management of epilepsy is widely acclaimed among communities in northern Nigeria. This study aimed at evaluating th...

Although ultrafast manipulation of magnetism holds great promise for new physical phenomena and applications, targeting specific states is held back by our limited understanding how magnetic correlations evolve on timescales. Using resonant inelastic x-ray scattering we demonstrate that femtosecond laser pulses can excite transient magnons at large wavevectors in gapped antiferromagnets, they p...
