Potential Use of Chitosan-TiO Nanocomposites for the Electroanalytical Detection of Imidacloprid.

The detection of toxic insecticides is a major scientific and technological challenge. In this regard, imidacloprid is a neonicotinoid that is a systemic insecticide that can accumulate in agricultural products and affect human health. This work aims to study the properties of chitosan-TiO nanocomposites in which nanoparticles with high surface area serve as molecular recognition sites for electroanalytical imidacloprid detection.

[A diagnostic approach to hepatic abscess].

Background: The non invasive diagnosis of amebic liver abscess allows the use of empirical therapy without the requirement of invasive diagnostic procedures.

Aim: To determine the discriminatory capacity of clinical, laboratory and ultrasound studies for the etiological diagnosis of liver abscess.

Patients And Methods: Sixty one patients were initially included in this prospective study, but 12 did not comply with the inclusion criteria.
