Anodic behavior of aripiprazole (ARP) was studied using electrochemical methods. Charge transfer, diffusion and surface coverage coefficients of adsorbed molecules and the number of electrons transferred in electrode mechanisms were calculated for quasi-reversible and adsorption-controlled electrochemical oxidation of ARP at 1.15 V versus Ag/AgCl at pH 4.0 in Britton-Robinson buffer (BR) on gla...

The effect of proximal epineural stripping on neuroma formation was studied in the peroneal nerve stumps of the rat. After transection of the peroneal nerve, the epineurium of the proximal stump was stripped back by 6 to 8mm and the nerve fascicles left uncovered in the study group. The transected nerve was left untreated in the control group. All nerves were evaluated by light microscopy 6 mon...

Carbon film disk electrodes with Nafion coatings have been characterized by electrochemical impedance spectroscopy (EIS) with a view to a better understanding of their advantages and limitations in electroanalysis, particularly in anodic stripping voltammetry of metal ions. After initial examination by cyclic voltammetry, spectra were recorded over the full potential range in acetate buffer sol...

Deposition and stripping of lead ions at thiol based disorganised monolayer modified gold piezoelectrodes was studied by cyclic voltammetry (CV) and electrochemical quartz crystal nanobalance (EQCN). Gold electrodes modified with 3-mercaptopropionic acid and 1,3-dimercapto propane sulphonic acid were studied. Due to the proximity of the potentials for the Pb deposition and thiol reductive desor...

In the present paper, we report on the use of adsorptive transfer stripping technique in connection with chronopotentiometric stripping analysis for metallothionein determination and of differential pulse anodic stripping voltammetry for lead detection in tissues of wild perch (Perca fluviatilis, n = 6) from the Svratka River in Brno, Czech Republic. Primarily, we determined the content of MT i...

To allow for geophysical interpretation of observed gravity gradients, several corrections must be applied. In this article expressions for gravimetric forward modeling of bathymetric (ocean density contrast) stripping corrections to GOCE gravity gradient observables are evaluated numerically. The generic expression for the bathymetric gravitational potential utilizes a depth-dependent seawater...

OBJECTIVE To examine the effects of immediate application of topical mitomycin C (MMC) on the prevention of anterior glottic stenosis (AGS) after microsurgical stripping of both vocal folds, including the anterior commissure, in a canine model. DESIGN Prospective randomized experimental study. INTERVENTIONS Twelve canine larynges were injured by a stripping procedure of both entire membrano...

Ram pressure stripping of the multiphase ISM is studied in the perturbed Virgo cluster spiral galaxy NGC 4438. This galaxy underwent a tidal interaction ∼ 100 Myr ago and is now strongly affected by ram pressure stripping. Deep VLA radio continuum observations at 6 and 20 cm are presented. We detect prominent extraplanar emission to the west of the galactic center, which extends twice as far as...
