Overview of Adductomics in Toxicology
Current Protocols, Volume 3, Issue 2, February 2023., 2023 Abstract Adductomics is epidemiology at the molecular level. Untargeted adductomics compares levels of chemical adducts on albumin, hemoglobin, and DNA between healthy and exposed individuals. The goal is to determine a cause‐and‐effect relationship between chemical exposure and illness. Chemical exposures are not necessarily due to synthetic chemicals

IL‐1β and Allergy: Focusing on Its Role in Allergic Rhinitis
Mediators of Inflammation, Volume 2023, Issue 1, 2023., 2023 Allergic rhinitis (AR) is a chronic upper airway immune‐inflammation response mediated by immunoglobulin E (IgE) to allergens and can seriously affect the quality of life and work efficiency. Previous studies have shown that interleukin‐1β (IL‐1β) acts as a key cytokine to participate in and promote the occurrence and development of allergic diseases ...

The Plant Journal, Volume 111, Issue 4, Page 954-965, August 2022., 2022 SUMMARY Plants are able to construct lineage‐specific natural products from a wide array of their core metabolic pathways. Considerable progress has been made toward documenting and understanding, for example, phenylpropanoid natural products derived from phosphoenolpyruvate via the shikimate pathway, terpenoid compounds built using isopentyl ...
