Maternal characteristics associated with the dietary intake of nitrates, nitrites, and nitrosamines in women of child-bearing age: a cross-sectional study

Environmental Health, 2010
Background Multiple N-nitroso compounds have been observed in animal studies to be both mutagenic and teratogenic. Human exposure to N-nitroso compounds and their precursors, nitrates and nitrites, can occur through exogenous sources, such as diet ...

BODIPY‐based J‐aggregates: From supramolecular chemistry to NIR bioimaging and phototherapies

Bulletin of the Korean Chemical Society, EarlyView.
BODIPY dyes form ordered J‐aggregates through controlled supramolecular self‐assembly, producing narrow, red‐shifted absorption bands with small Stokes shifts. This review highlights design strategies governing J‐aggregation, structure–property relationships, and applications in sensing, bioimaging, and phototherapy, guiding functional BODIPY‐based ...

Chemistry Underlying the Behavior of Food and Agricultural Components During Industrial Manufacturing Processes and Its Implications in Quality Assurance, Food Quality, and Food Safety Management: A Systematic Review

Food Safety and Health, EarlyView.
Industrial manufacturing processes have transformative effects on the components of food matrix. These transformations in food matrix and components have direct implications for quality assurance (QA), food quality (e.g., nutritional profile and texture), and food safety management (e.g., pathogen control and toxin mitigation). ABSTRACT This systematic
