Giant rhinoliths are uncommon, mineralized concretions that usually develop around an intranasal foreign substance in the nasal canal. These lesions frequently cause respiratory problems, foul-smelling discharge, and nasal blockage. Clinical examination, endoscopy, and radiological imaging are used to make the diagnosis, and surgical removal is the only effective therapy.

Perfluoroalkyl and polyfluoroalkyl substances (PFAS) and herbicides are important persistent contaminants that require specific management. A variety of herbicides is stored in fluorinated containers in the form of aquatic solutions. In such environments, the simultaneous release of PFAS and herbicides takes place.

Background: Osteopenia (ON) and osteoporosis (OP) are highly prevalent among postmenopausal women and poses a challenge for early diagnosis. Therefore, identifying reliable biomarkers for early prediction using metabolomics is critically important.
Methods: Initially, non-targeted metabolomics was employed to identify differential metabolites in plasma samples from cohort 1, which included healthy controls (HC, n = 23), osteonecrosis (ON, n = 36), and osteoporosis (OP, n = 37).

Accurate determination of nutrients in food is becoming increasingly important. Minerals and other trace elements can be determined by a variety of highly sensitive methods, but complete mineralization of the sample is essential for correct quantification. Hydrogen peroxide is a key reagent for destruction of organic matter in conjunction with sulfuric acid.

Perfluorinated compounds (PFAS) are well recognized toxic pollutants for humans, but if their effect is equally harmful for healthy and fragile people is unknown. Addressing this question represents a need for ensuring global health and wellbeing to all individuals in a world facing the progressive increase of aging and aging related diseases. This study aimed to evaluate the impact of perfluorooctane sulfonate (PFOS), perfluorooctanoic acid (PFOA) and perfluorohexanoic acid (PFHxA) exposure on development and skeletal phenotype using the osteogenesis imperfecta (OI) zebrafish model Chihuahua (Chi/+), carrying a dominant glycine substitution in the α1 chain of collagen I and their wild-type (WT) littermates.
