Rat liver antioxidant response to iron and copper overloads [PDF]

open access: yes, 2014
The rat liver antioxidant response to Fe and Cu overloads (0–60 mg/kg) was studied. Dose- and time-responses were determined and summarized by t1/2 and C50, the time and the liver metal content for half maximal oxidative responses.

Antioxidants Maintain Cellular Redox Homeostasis by Elimination of Reactive Oxygen Species

open access: yesCellular Physiology and Biochemistry, 2017
Reactive oxygen species (ROS) are produced by living cells as normal cellular metabolic byproduct. Under excessive stress conditions, cells will produce numerous ROS, and the living organisms eventually evolve series of response mechanisms to adapt to ...

Acacetin reduces endoplasmic reticulum stress through the P‐eNOS/PERK signaling pathway to attenuate MGO‐induced vascular endothelial cell dysfunction

open access: yesFEBS Open Bio, EarlyView.
We investigated a potential protective effect of acacetin, a naturally occurring flavonoid, against methylglyoxal (MGO)‐induced endothelial dysfunction in human umbilical vein endothelial cells and its mechanism of action. Acacetin can could inhibit MGO‐induced intracellular calcium ion influx, enhance the expression levels of phosphorylated ...

Metal oxide nanoparticle based electrochemical sensor for total antioxidant capacity (TAC) detection in wine samples [PDF]

open access: yes, 2018
A single-use electrochemical screen-printed electrode is reported based on biomimetic properties of nanoceria particles (CeNPs). The developed tool showed an easy approach compared to the classical spectrophotometric methods reported in literature in ...

Hydrogen sulfide repairs testicular damage induced by heat stress in rats

open access: yesFEBS Open Bio, EarlyView.
Heat stress can cause testicular damage and affect fertility. We investigated the potential protective role of hydrogen sulfide (H2S) against heat stress‐induced testicular injury and observed that H2S donor NaHS can effectively restore testicular damage in rats by inhibiting inflammation and oxidative stress. Our results suggest that H2S might be used

Reactive Oxygen Species (ROS) Metabolism and Nitric Oxide (NO) Content in Roots and Shoots of Rice (Oryza sativa L.) Plants under Arsenic-Induced Stress

open access: yesAgronomy, 2020
Arsenic (As) is a highly toxic metalloid for all forms of life including plants. Rice is the main food source for different countries worldwide, although it can take up high amounts of As in comparison with other crops, showing toxic profiles such as ...

Emerging classes of antioxidant to cancer therapy: a review of clinical and experimental studies [PDF]

open access: yesarXiv, 2020
This review mainly focuses on the relation between antioxidants with cancer therapy. Antioxidants have been reported to play an essential role to reduce free radical species. Free radicals commonly cause oxidative damage which is a common factor in the aging process, and also the vital factor of formation, and development of major disease specially ...

Establishment and biological characterization of radioresistant colorectal cancer cell lines

open access: yesFEBS Open Bio, EarlyView.
Under ionizing radiation exposure, radiation‐sensitive cancer cells exhibit oxidative stress and DNA damage, while radiation‐resistant cancer cells exhibit strong antioxidant properties and DNA damage repair. Radiotherapy resistance is a major cause of recurrence and metastasis in colorectal cancer (CRC).

Impact of Nitric Oxide (NO) on the ROS Metabolism of Peroxisomes

open access: yesPlants, 2019
Nitric oxide (NO) is a gaseous free radical endogenously generated in plant cells. Peroxisomes are cell organelles characterized by an active metabolism of reactive oxygen species (ROS) and are also one of the main cellular sites of NO production in ...
