New Electrochemical Detection Strategies for Iodinated Compounds

Abstract

Iodine is a micronutrient of high importance for the health and good development of individuals. It is contained in many foods, but it is also part of the chemical component of oceans and soil. Its deficiency is still a problem of humanity, which has a serious repercussion on our health. It is therefore important to have specific, fast and cost effective methods of iodine detection from different samples. This work aims to identify optimal parameters for potassium iodide (KI) detection from different media, to be further applied to real samples: plant extracts, water, biological fluids. Results showed a significant difference in electrochemical results, depending on the pH values of the mixture and also on the time which influences the compounds stability. Differential pulse voltammetry and cyclic voltammetry using carbon printed sensors, as well as microsensors for redox status or direct iodide detection are important analytical tools which have a wide range of applications in the food, medicine, toxicology and other domains.

Incidence and Clinical Implications of Autoimmune Thyroiditis in the Development of Acne in Young Patients

“…Second, although detailed information of the patients’ history was obtained at the time of examination, the use of other medications (including thyroid related) and the presence of thyroid diseases (goiter) were self-reported. Moreover, it must be underlined that urinary iodine excretion was not measured, even though this research was conducted in an iodine sufficient country [ 40 ]. The following are among the strengths of the study: unlike other studies that investigate the severity of acne in patients with antithyroid antibodies compared with a control group (without acne), this study investigates the incidence of AIT in patients with acne and evaluates its severity, compared with both patients with acne without AIT, and depending on the presence and levels of TG and TPO (separately and together, in the group with AIT).…”
