Article En MEDLINE ID: mdl Humans are exposed to multiple chemicals on a daily basis instead of to just a single chemical, yet the majority of existing toxicity data comes from single-chemical exposure. Multiple factors must be considered such as the route, concentration, duration, and the timing of exposure when determining toxicity to the organism.
Human papilloma virus apprehending the link with carcinogenesis and unveiling new research avenues need for adequate model systems in vivo, in vitro, in silico and mathematical is paramount for better understanding of chemical mixture toxicity. Currently, shortcomings plague each model system as investigators struggle to find the appropriate balance of rigor, reproducibility and appropriateness in mixture toxicity studies.
Rom J Morphol Embryol ; 57 2 Suppl : Article En MEDLINE ID: mdl Lichen sclerosus et atrophicus and limited systemic scleroderma acrosclerosis are inflammatory skin diseases that ultimately evolve into two distinct modes of atrophic scar formation, but which can easily be confused clinically.
Significant questions exist when comparing single-to mixture-chemical toxicity concerning additivity, synergism, potentiation, or antagonism. Previous work was limited by the technology and methodology of the time, but recent advances have resulted in significant progress in the study of mixture toxicology.
Novel technologies have added insight to data obtained from in vivo studies for predictive toxicity testing. These include new in vitro models: omics-related tools, organs-on-a-chip and 3D cell culture, and in silico methods.
Taken together, all these modern methodologies improve the understanding of the multiple toxicity pathways associated with adverse outcomes e. As technology and knowledge advance, our ability to harness and integrate separate streams of evidence regarding outcomes associated with chemical mixture exposure improves.
As many national and international organizations are currently stressing, studies on chemical mixture toxicity are of primary importance.
