Eggshell‐Based Biochar for Superior Adsorption of Crystal Violet Dye and Fluoride From Wastewater

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Present study investigates the efficiency of eggshell biochar as a low‐cost and ecofriendly adsorbent for the simultaneous removal of fluoride ions and crystal violet (CV) dye from wastewater. The eggshell waste was pyrolyzed to produce biochar, which was thoroughly characterized and subsequently employed for contaminant adsorption.

Enhanced Production of Astaxanthin and Zeaxanthin by Paracoccus Sp. LL1 Through Random Mutagenesis

Biotechnology and Applied Biochemistry, EarlyView.
ABSTRACT Astaxanthin, a high‐value carotenoid with potent antioxidant and anti‐inflammatory activities, is increasingly in demand in various industries. This study reports the successful enhancement of astaxanthin and zeaxanthin production in Paracoccus sp. LL1 through random mutagenesis using ethyl methanesulfonate (EMS).

Dietary meat mutagens intake and cancer risk: A systematic review and meta-analysis

Frontiers in Nutrition, 2022
BackgroundClinical and preclinical studies suggested that certain mutagens occurring as a reaction of creatine, amino acids, and sugar during the high temperature of cooking meat are involved in the pathogenesis of human cancer.

Navigating the Genetic Risk of Chemotherapy‐Induced Hearing Loss in the Stria Vascularis

Clinical Pharmacology &Therapeutics, EarlyView.
Cisplatin is a chemotherapy drug that causes permanent hearing loss by damaging a critical tissue lining the inner ear, called the stria vascularis (SV). Currently, the molecular mechanisms of SV damage are largely unknown and the incidence of ototoxicity in patients cannot be reliably predicted.

Interpretation of in vitro concentration‐response data for risk assessment and regulatory decision‐making: Report from the 2022 IWGT quantitative analysis expert working group meeting

Environmental and Molecular Mutagenesis, EarlyView.
Abstract Quantitative risk assessments of chemicals are routinely performed using in vivo data from rodents; however, there is growing recognition that non‐animal approaches can be human‐relevant alternatives. There is an urgent need to build confidence in non‐animal alternatives given the international support to reduce the use of animals in toxicity ...

Severity of effect considerations regarding the use of mutation as a toxicological endpoint for risk assessment: A report from the 8th International Workshop on Genotoxicity Testing (IWGT)

Environmental and Molecular Mutagenesis, EarlyView.
Abstract Exposure levels without appreciable human health risk may be determined by dividing a point of departure on a dose–response curve (e.g., benchmark dose) by a composite adjustment factor (AF). An “effect severity” AF (ESAF) is employed in some regulatory contexts.
