Article
This article reports the procedure adopted to perform linear sweep voltammetry (LSV) and cyclic voltammetry (CV) and summarizes the main information obtained using these electrochemical techniques. In particular, a general overview of the considerable insight into electrochemical processes that can be gained using LSV and CV experiments is presente...

A linear sweep voltammetric (LSV) approach is proposed for achieving rapid information on metal release from tinned containers into preserved vegetables. Chopped tomato and pea preserves were chosen as prototypes for acid and nearly neutral canned food, respectively. Metal release in these vegetables tinned into both bare and lacquered containers w...
Article
Full-text available
An improved single step microwave digestion procedure is described for providing the fast and easy exhaustive mineralisation of biological samples concomitantly with the quantitative conversion of any type of selenium compounds into Se(IV). In such a way, digested samples are directly suitable for the subsequent Se analysis at trace and ultratrace...
Article

A reverse-phase HPLC method for the simultaneous determination of the main artificial sweeteners, preservatives and dyes present in soft drinks is proposed. It involves the use of a 10 μm LiChrosorb RP18 column and a binary eluent consisting of aqueous 0.1 M phosphate buffer (pH 4.0) added with methanol, according to a suitable gradient elution pro...
Article
A simple electronic pulse generator based on an organic switch, a device made of poly(5-amino-1-naphthol) between silver contacts is demonstrated. Under a constant applied voltage the circuit oscillates, producing current pulses at a frequency that can be controlled, depending on the resistance and capacitance of circuit elements.
Article
The redox properties of lacidipine (PyH2), one of the most pharmacologically active N-unsubstituted 1,4-dihydropyridines, have been studied by cyclic voltammetry and controlled potential electrolysis in acetonitrile, an aprotic solvent that is, at best, a mimic of the lipofilic layer of biological membranes. PyH2 undergoes a two-electron oxidation...
Article
The effect on the formation of both oxygenated polyatomic and doubly charged ions in inductively coupled plasma mass spectrometry (ICP-MS) has been evaluated for sample introduction with three different injection devices. An ultrasonic nebulizer (USN) equipped with an efficient membrane desolvator, in addition to a usual desolvation module incorpor...
Article
Voltammetry at electrodes modified with ion-exchange polymers, named "ion exchange voltammetry", has been recently developed for characterizing and determining quantitatively ionic electroactive analytes preconcentrated at the electrode surface. Like for other voltammetric techniques, characterization is based on the position of the response on the...
Article
The authors explain the general criteria in performing an ultrasound exam and the pathological finding of congenital dislocation of the hip. They based the study on the screening of 500 patients between the ages of ten days and eight months (2% of which resulted pathological) and on evaluation of 80 cases of dislocated hip not included in the origi...
Article
The authors report two cases of Freeman-Sheldon syndrome, characterised by recessive autosomic transmission, affecting a brother and a sister born of parents who were not blood relations. The syndrome, for which 50 cases are described in the literature, takes its name from the authors who were the first to describe it in 1938. The typical picture i...
Article
The authors report a series of affections which determine diffused modifications of the skeleton during early childhood. More common pathological forms are dealt with, of relatively simple diagnosis, and having pathological pictures which based on frequency, means of occurrence, and clinical-radiographic aspects, are rarely observed, and difficult...
Article
Based on their observation of approximately 1000 patients aged from 4 to 14 years and on a comparison of their experience with the data reported in the literature, the authors discuss the problem of modifications in torsion of the lower limbs during pediatric age. After a brief discussion of anatomy and the natural progression of the angle of femor...
