Description

Application

• Histological and Chemical Analysis of Heavy Metals in Kidney and Gills of Boops boops: Melanomacrophages Centers and Rodlet Cells as Environmental Biomarkers.: This study utilized periodic acid in the analytical characterization of heavy metals in marine organisms, providing insights into environmental biomarkers relevant for chemical analysis in aquatic settings (Lauriano ER et al., 2022).


• Histochemical study of the effects on abomasal mucins of Haemonchus contortus or Teladorsagia circumcincta infection in lambs.: Investigates the interaction between parasitic infections and mucosal surfaces, where periodic acid staining could be applied to analyze mucin carbohydrates (Savoian MS et al., 2016).
