General description

tert-Butylhydroquinone (TBHQ) is a phenolic antioxidant. TBHQ is frequently used as a food preservative. In low concentrations it shows cytoprotective qualities while at higher concentrations it exhibits cytotoxic behavior.

Application

TBHQ was used to study the inactivation of barotolerant strains of Listeria monocytogenes and Escherichia coli. Environment friendly electrode materials for supercapacitors were attained by decorating the surface of graphene nanosheets with TBHQ.

Antimicrobial efficacy of ultra-high-pressure (UHP) can be enhanced by application of additional hurdles. The objective of this study was to systematically assess the enhancement in pressure lethality by TBHQ treatment, against barotolerant strains of Escherichia coli O157:H7 and Listeria monocytogenes.

The stratum corneum protects against the entry of pathogens, allergens, and irritants while preventing dehydration. The Kelch-like erythroid cell-derived protein with cap-n-collar homology-associated protein 1 (KEAP1)/NF-E2-related factor 2 (NRF2) system maintains skin barrier homeostasis. Aggregated evidence suggests that NRF2-mediated antioxidative

Radiotherapy and chemotherapeutic agents can effectively induce apoptosis through generation of reactive oxygen species (ROS). Cancer cells frequently express high levels of ROS-scavenging enzymes, which confer resistance to ROS-mediated cell death. Keap1 (Kelch-like ECH-associated protein 1) sequesters and promotes the
