Evaluation of DNA/Chromosome Integrity and Cell Death in Human Metabolically Noncompetent and Competent Cells Exposed to N′‐(3,5‐Difluorobenzylidene)Pyridine‐4‐Carbohydrazide

Journal of Applied Toxicology, EarlyView.
ABSTRACT The N‐acylhydrazone scaffold is recognized as a privileged structure for the design of bioactive substances with increasing applications in medicinal chemistry research. Ensuring the safety of newly developed molecules is a critical step for both human health and environmental protection. Accordingly, this study aimed to evaluate the cytotoxic

Assessing Metabolic and Reproductive Consequences of Prenatal Paracetamol Exposure in Female CD1 Mice

Journal of Applied Toxicology, EarlyView.
ABSTRACT Paracetamol is a widely used analgesic during pregnancy; however, emerging evidence suggests it may act as an endocrine/metabolism disrupting compound. Using an F1 female CD1 mouse model, this study scrutinized the long‐term metabolic and reproductive consequences linked to intrauterine paracetamol exposure.

Polarity‐engineered Sn‐Ti cluster photoresists for sub‐10‐nm high‐resolution lithography

Smart Molecules, EarlyView.
Enhancing the polarity of clusters can optimize their patterning performance; inspired by this strategy, we designed polarity‐enhanced Sn‐Ti oxo clusters via ligand engineering. The optimal TS‐3 with exposure‐induced polarity switch achieves 8 nm patterning in lithography and achieves simultaneous improvement in resolution and patterning performance ...
