Ebook "Studies on women’s health (Oxidative stress in applied basic research and clinical practice series)" covers data describing the role of free radicals and antioxidants that deal with clinical and pre-clinical trials, as well as basic research in the area of women's health. There is increasing evidence that oxidative stress is a causative, or at least a supporting factor in female pathology and infertility. During advancing gestational age, oxidative stress biomakers rise.

Overproduction of reactive oxygen species (ROS) in plant cells under environmental stress cause oxidative stress, which is one of major factors limiting the plant productivity. To prevent this limitation by stress conditions, a possible strategy is to strengthen the antioxidant defense of plants by gene manipulation of antioxidant enzymes and low molecular-weight (LMW) antioxidants. LMW antioxidants are important for the plant protection to environmental stress and also have nutritional merits for humans as antiaging and antidisease molecules.

The aim of this work was to understand involvement of PARylation in inducing enzymatic antioxidant defence and alternative electron sinks in response to salinity. For this purpose A. thaliana plants were treated with 3-aminobenzamide (3-AB), which is a PARP inhibitor, in the presence of 100 mM NaCl. The 3-AB treatment induced plant fresh weight under control and salinity conditions. Moreover, 100 mM NaCl + 3-AB treated plants had lower lipid peroxidation when compared to 100 mM NaCl group indicating mitigation of oxidative stress.

The present study evaluated the possible potential of amino acids in enhancing the salinity tolerance in spinach and identified the probable underlying mechanisms. The experiment comprised of two factors viz. amino acids with total of seven treatments; control, salinity (sal) 100 mM, Methionine + sal, Phenylalanine + sal, Proline + sal, Tyrosine + sal, Combined amino acids + sal, and two spinach cultivars (Desi Palak and VRI-2019).

Accumulation of the signal adaptor protein p62 has been demonstrated in many forms of cancer, including pancreatic ductal adenocarcinoma (PDAC). Although data from experimental studies suggest that p62 accumulation accelerates the development of PDAC, the association between p62 protein expression and survival in PDAC patients is unclear.

High concentrate (HC) diet-induced oxidative stress causes gut epithelial damages associated with apoptosis. Selenium (Se) being an integral component of glutathione peroxidase (GSH-Px) plays an important role in antioxidant defense system. Therefore, increasing dietary Se level would alleviate HC diet-induced injuries in gut mucosa.

Vitamins are regarded as vital growth substances. They act as cofactors of various key enzymes involved in metabolism and also have vital influence on metabolic activities of plants. They are believed to play a significant role in plants against abiotic stresses, particularly during water stress. The current experiment was conducted to evaluate the role of exogenously applied thiamin on two white clover cultivars, Super Late Fsd and Layalpur Late, at varying [100% (control), 80%, and 60% field capacities] water regimes.

Excessive amounts of reactive oxygen species (ROS), unless counterbalanced by antioxidants, can cause cellular damage under oxidative stress conditions; therefore, antioxidative defenses against ROS must be measured. With the development of nanotechnology, nanoparticles have found numerous applications in science, health, and industries. Magnetite nanoparticles (Fe3O4 :MNPs) have attracted attention because of their peroxidase-like activity.

Reactive oxygen species (ROS) or oxidative stress has been reported with strongly involving to pathogenesis of many diseases in human. On the other hand, ROS play a critical regulation as secondary signal to maintain intracellular redox equilibrium. Basically, the antioxidant defense systems in the body counteract with overproduced ROS. However, when the redox balance is broken under severe oxidative stress conditions, it leads to tissue injuries and numerous disorders.

The present study was undertaken on 60 adult female Sprague Dawley rats (275±2.04 g) for an experimental duration of 84 days to evaluate various organic sources of zinc on immunity, reproduction, oxidative defense mechanism in rats. The rats were randomly allotted to 5 dietary treatments (6 replicates in each) prepared by varying the source of Zn supplementation (12 ppm) either from inorganic (Zn carbonate) or sources (Zn proteinate, Zn propionate, Zn amino acid complex and Zn methionine).

Nuclear factor erythroid-2 related factor 2 (Nrf2) is a crucial transcription factor that regulates the expression of defensive antioxidants and detoxification enzymes in cells. In a previous study, we showed that expression of the Nrf2 gene is regulated by an epigenetic modification. Rauvolfia verticillata, a traditional Chinese herbal medicine widely used in China, possesses anticancer and antioxidant effects. In this study, we investigated how Nrf2 is epigenetically regulated by reserpine, the main active component in R. verticillata, in mouse skin epidermal JB6 P+ cells.

We compared the enzymatic antioxidative defence mechanisms of some regional soybean genotypes cultivated mainly in the regions of Maharashtra and Chhattisgarh. The variability in the activities of antioxidant enzymes superoxide dismutase (SOD), ascorbate peroxidase (APX), catalase (CAT), and peroxidase (POD) and their changes under drought stress were investigated. The higher activity levels of antioxidant enzymes may contribute to better stress tolerance by increasing protection capacity against oxidative damage.

The results indicated that exposure to 10 and 30 µg L–1 Pb2+ significantly altered the activities of catalase, superoxide dismutase, and glutathione peroxidase in different tissues, while malondialdehyde content increased in a time- and concentration-dependent manner. Inhibition of AchE after chronic exposure also confirmed a generalized neurotoxic stress.
