By measuring the defense behavior in response to the noxious stimulation induced by potassium iontophoresis on ear-lobe skin of conscious rabbit, chlorpromazine (CPZ) (0.5 mg.kg-1, i.v.) induced hyperalgesia, whereas it significantly attenuated electroacupuncture analgesia (EAA) efficacy. Monoamines and their metabolites in cerebrospinal fluid (CSF) were measured by high pressure liquid chromat...

A method for the determination of Thiamethoxam in bee samples was set up by means of high performance liquid chromatography with an electrochemical detector and post-column photochemical reactor (HPLC-h nu-ED). Analytical method was based on a rapid sample extraction procedure with acetone, followed by chromatographic separation into a C18-RP column isocratically operated by 60 mM phosphate buf...

We propose a super resolution imaging technique called plasmonic structured illumination microscopy (PSIM), which combines the structured illumination microscopy technique with the tunable surface plasmon interference. Because of the high-resolution enabled by using surface plasmon interference as an illumination source, PSIM possesses higher image resolving power compared with conventional str...

Electrochemical hydrazine oxidation and proton reduction occur at a significantly higher rate at Pt than at Au or C electrodes. Thus, the collision and adhesion of a Pt particle on a less active Au or C electrode leads to a large current amplification by electrocatalysis at single nanoparticles (NPs). At low particle concentrations, the collision of Pt NPs was characterized by current transient...

A rapid isocratic method of high performance liquid chromatography system (HPLC) with a glassy carbon working electrode of electrochemical detector is set up for quantitative detection of trace amount of nitrite ion (NO2) in aqueous protein containing cell lysate, cell media, plasma, serum, urine and other body fluids. The solid extraction reversed phase cartridges (Sep-pak) are used for deprot...

Amlodipine is a calcium channel antagonist of the dihydropyridine group. It is effective for treating hypertension, chronic stable angina, and vasospastic angina. However, it is difficult clinically to pinpoint the maximum dosage for antihypertensive activity of the drug without having parallel data on the plasma drug concentrations. The methods for assaying amlodipine are either gas chromatogr...

INTRODUCTION Polyphosphates are used for a wide variety of industrial applications due to their sequestering and dispersing properties. Polyphosphate samples are commonly characterized by various end-group titration methods that provide an estimate of average polyphosphate chain length, but no information on the relative amounts of individual polyphosphate oligomers. Manufacturers and end-users...

in this paper, the detector of moving target in mimo radar with widely separated antenna in the presence of α-stable clutter is proposed. due to the complexity of unknown parameter estimation in the presence of target, the rao test is applied. the α-stable model is a general model that can applied to different environments with appropriate selection of parameters. the problem with this model is...
