Quality of life in adolescent and adult patients with persistent allergic rhinitis after one year of subcutaneous immunotherapy with a modified mite extract.

Introduction: Allergic rhinoconjunctivitis (AR) is an IgE-mediated inflammation of nasal and ocular mucosa after environmental allergen exposure, mainly by house dust mites (HDM). AR affects more than one third of the population worldwide and it is associated with loss of quality of life (QoL).

Aim: To analyse the improvement in the QoL in 50 patients with moderate-persistent AR due to house HDM before and after receiving 1 year of subcutaneous specific aeroallergen immunotherapy treatment (SAIT).

Hexyltrimethylammonium ion enhances potential copper-chelating properties of ammonium thiomolybdate in an in vivo zebrafish model.

Ammonium and hexyltrimethylammonium thiomolybdates (ATM and ATM-C6) and thiotungstates (ATT and ATT-C6) were synthesized. Their toxicity was evaluated using both in vitro and in vivo approaches via the zebrafish embryo acute toxicity assay (ZFET), while the copper-thiometallate interaction was studied using cyclic voltammetry, as well as in an in vivo assay. Cyclic voltammetry suggests that all thiometallates form complexes with copper in a 2:1 Cu:thiometallate ratio.
