It has been established by methods of spectrophotometry and spin probe that the organophosphorus pesticide metaphos, widely used in practice, is an inhibitor of NADH2 oxidase of the respiratory chain of the mitochondria and exerts an influence on the structural organization of the mitochondrial membrane. An effect of metaphos on the nature of the distribution and kinetics of NADH2-induced death of monoradical spin probes of various chemical structures was detected in a suspension of submitochondrial particles obtained from beef heart.

The coexistence of type 2 diabetes mellitus (T2DM) and chronic kidney disease (CKD) represents a significant global health challenge, contributing to substantial morbidity, mortality, and economic burden. T2DM is the leading cause of CKD, and CKD exacerbates diabetes-related complications, creating a bidirectional relationship driven by oxidative stress, inflammation, and endothelial dysfunction. Diabetic kidney disease (DKD), affecting some individuals with T2DM, accelerates progression to end-stage renal disease (ESRD) and increases cardiovascular mortality.

p-Phenylenediamines (PPDs) are widely used as antioxidants in numerous rubber products to prevent or delay oxidation and corrosion. However, their derived quinones (PPD-Qs), generated through reactions with ozone, are ubiquitous in the environment and raise significant health and toxicity concerns. This review summarizes the current state of knowledge on environmental distribution and fate, human exposure, and biological toxicity of PPDs and PPD-Qs, and makes recommendations for future research directions.

The Chinese mitten crab (Eriocheir sinensis) is an important component in Chinese aquaculture. Due to its lacking adaptive immune system as a crustacean, it exhibits poor tolerance to environmental stresses, particularly the deleterious impact of lipopolysaccharide (LPS) from pathogenic bacteria during E. sinensis culture.

A pivotal pathway of photodynamic therapy (PDT) is to prompt mitochondrial damage by reactive oxygen species (ROS) generation, thus leading to cancer cell apoptosis. However, mitochondrial autophagy is induced during such a PDT process, which is a protective mechanism for cancer cell homeostasis, resulting in undermined therapeutic efficacy. Herein, we report a series of meticulously designed donor (D)-π-acceptor (A) photosensitizers (PSs), characterized by the strategic modulation of thiophene π-bridges, which exhibit unparalleled mitochondrial targeting proficiency.

A water extract of the Ayurvedic plant (L.) Urban, family Apiaceae (CAW), improves cognitive function in mouse models of aging and Alzheimer's disease and affects dendritic arborization, mitochondrial activity, and oxidative stress in mouse primary neurons. Triterpenes (TT) and caffeoylquinic acids (CQA) are constituents associated with these bioactivities of CAW, although little is known about how interactions between these compounds contribute to the plant's therapeutic benefit.
