Zhejiang Province Key Laboratory of Plant Secondary Metabolism and Regulation, College of Life Sciences and Medicine, Zhejiang Sci-Tech University, Hangzhou, 310018, China.
Tetrastigma hemsleyanum, a traditional Chinese medicinal plant with anti-inflammatory, anti-cancer, and anti-tumor properties, faces increasing abiotic stress due to climate change, agricultural chemicals, and industrialization. This study investigated how three abiotic stress factors influence antioxidant enzyme activity, MDA levels, DPPH free radical scavenging capacity, chlorophyll, carotenoids, active compounds, and gene expression in different T. hemsleyanum strains.

Over 10% of the global population is at risk to kidney disorders. Nuclear factor erythroid-derived 2-related factor 2 (NRF2), a pivotal regulator of redox homeostasis, orchestrates antioxidant response that effectively counters oxidative stress and inflammatory response in a variety of acute pathophysiological conditions, including acute kidney injury (AKI) and early stage of renal toxicity. However, if persistently activated, NRF2-induced transcriptional cascade may disrupt normal cell signaling and contribute to numerous chronic pathogenic processes such as fibrosis.

Nanotechnology offers a transformative approach to augment plant growth and crop productivity under abiotic and biotic stress conditions. Nanomaterials interact with key phytohormones, triggering the synthesis of stress-associated metabolites, activating antioxidant defense mechanisms, and modulating gene expression networks that regulate diverse physiological, biochemical, and molecular processes within plant systems. This review critically examines the impact of nanoparticles on both conventional and genetically modified crops, focusing on their role in nutrient delivery systems and the modulation of plant cellular machinery.

Recurrent pregnancy loss (RPL) is the occurrence of two or more consecutive miscarriages before 20 weeks of gestation. Recent research has increasingly focused on the role of oxidative stress in RPL, providing insights into its underlying mechanisms and potential therapeutic targets. Oxidative stress arises from an imbalance between reactive oxygen species (ROS) production and antioxidant defenses, leading to cellular damage and inflammation.
