Reactive oxidants

In this study, green-synthesized zinc oxide nanoparticles (ZnO NPs) were surface-modified with pluronic F-127 after being synthesized using the leaf extract of guava (Psidium guajava). The resulting material, ZnO@F-127, was then characterized, and its anticancer activity was evaluated on several cell lines.

The study was carried out to investigate lipid and protein oxidation of herring (Sardinella gibbosa) that was treated with (2.5% w/v) sodium acetate at 4o C. After 3, 6, 9, and 12 days, lipid and protein oxidation were evaluated by indications such as pH value, peroxide (PV), thiobarbituric acid-reactive substances (TBARS), protease enzyme activity and sulfhydryl.

The results showed that the overall diffusioncontrolled rate constant is equal to 4.82×109 M-1 s -1 at 298.15K. The zwitterionic form is the main existing form that plays an essential role in the HO - initiated oxidation of Ile (99.98%). The most preponderant reactions are found at C6-H (36.19%) and C8-H (37.77%) positions. Finally, the influence of temperature on the overall rate is also evaluated.

Ebook "Novel synthetic chemistry of ureas and amides" investigates the chemistry and application of molecules containing urea and amide bonds. These bonds are some of the strongest known and are fundamental to biological processes. The author describes his discovery that sterically hindered ureas undergo solvolysis at room temperature under neutral conditions. This is a remarkable finding, since ureas are inert under these conditions and a general rule of chemistry is that hindered substrates are less reactive.

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.
