The Roles of Environmental Factors in Regulation of Oxidative Stress in Plant

BioMed Research International, Volume 2019, Issue 1, 2019., 2019
Exposure to a variety of environmental factors such as salinity, drought, metal toxicity, extreme temperature, air pollutants, ultraviolet‐B (UV‐B) radiation, pesticides, and pathogen infection leads to subject oxidative stress in plants, which in turn affects multiple biological processes via reactive oxygen species (ROS) generation.

Enhanced Reactive Oxygen Species Scavenging by Overproduction of Superoxide Dismutase and Catalase Delays Postharvest Physiological Deterioration of Cassava Storage Roots1[C][W][OA]

Plant Physiology, 2013
Overproduction of the copper/zinc superoxide dismutase and catalase in transgenic cassava dramatically improves ROS scavenging ability, abiotic stress resistance, and delayed postharvest deterioration.

Reactive Oxygen Species (ROS) and Antioxidant Systems in Enhancing Plant Resilience Against Abiotic Stress

International Journal of Agronomy, Volume 2025, Issue 1, 2025.
Reactive oxygen species (ROS) are central to plant responses under abiotic stress, acting as both damaging agents and signaling molecules. This study explores the balance between ROS production, oxidative damage, and the antioxidant defense mechanisms in plants.

Niphargus–Thiothrix associations may be widespread in sulphidic groundwater ecosystems: evidence from southeastern Romania

Molecular Ecology, Volume 23, Issue 6, Page 1405-1417, March 2014., 2014
Abstract Niphargus is a speciose amphipod genus found in groundwater habitats across Europe. Three Niphargus species living in the sulphidic Frasassi caves in Italy harbour sulphur‐oxidizing Thiothrix bacterial ectosymbionts. These three species are distantly related, implying that the ability to form ectosymbioses with Thiothrix may be common among ...

Molecular evolution and interaction of ROS with ion transport for plant abiotic stresses

New Plant Protection, Volume 1, Issue 2, December 2024.
Through a comprehensive review of the literature and analyses of the molecular evolution and comparative genetics of ROS‐regulated proteins and Shaker‐type K+ channels, we propose that ROS‐regulated proteins are essential players in response to and adaptation to abiotic stresses in green plants.

Ischaemic Heart Disease: Accuracy of the Prehospital Diagnosis—A Retrospective Study

Emergency Medicine International, Volume 2013, Issue 1, 2013., 2013
Purpose. Correct prehospital diagnosis of ischaemic heart disease (IHD) may accelerate and improve the treatment. We sought to evaluate the accuracy of prehospital diagnoses of ischemic heart diseases assigned by physicians. Methods. The Mobile Emergency Care Unit (MECU) in Odense, Denmark, services a population of 260.000.

Reductive Elimination From Tetra‐Alkyl Cuprates [MenCu(CF3)4−n]− (n=0–4): Beyond Simple Oxidation States

Angewandte Chemie International Edition, Volume 63, Issue 44, October 24, 2024.
The full series of high‐valent cuprates [MenCu(CF3)4−n]−, 0≤n≤4, has been studied by a combination of gas‐phase fragmentation experiments and quantum chemical calculations. The distinct reactivities observed can be attributed to subtle differences in the electronic structures of the complexes.

Lipothymia and Syncope—Aetiology and Outcome in a Prehospital Setting: A Retrospective Study

International Scholarly Research Notices, Volume 2012, Issue 1, 2012., 2012
Background. A firm aetiology of lipothymia or syncope can be difficult to establish prehospitally. The aim of the study was to investigate patients initially assigned the diagnosis of lipothymia or syncope prehospitally and establish the aetiology of their condition either based on prehospital or in‐hospital medical records. Methods.

Integrating Anaerobic Digestion With Struvite Production for Enhanced Nutrient Recovery, Pathogen Reduction, and Circularity in Manure Management

Journal of Sustainable Agriculture and Environment, Volume 3, Issue 4, October 2024.
ABSTRACT Introduction Anaerobic digestion (AD) is essential for manure management, generating biogas and nutrient‐rich digestate for organic fertilizer. However, improper digestate use can pose environmental risks. Recovering struvite, a magnesium ammonium phosphate (MAP) compound, from digestate provides a sustainable, controlled‐release fertilizer ...

Increased expression of native cytosolic Cu/Zn superoxide dismutase and ascorbate peroxidase improves tolerance to oxidative and chilling stresses in cassava (Manihot esculenta Crantz)

BMC Plant Biology, 2014
BackgroundCassava (Manihot esculenta Crantz) is a tropical root crop, and is therefore, extremely sensitive to low temperature; its antioxidative response is pivotal for its survival under stress. Timely turnover of reactive oxygen species (ROS) in plant
