1. In this study an acute anti-hypertensive effect of three anti-oxidant agents (vitamin C, thiopronine and glutathione) in hypertensive subjects and in both hypertensive and non-hypertensive diabetic patients is reported. 2. The anti-oxidants had no effect on blood pressure in healthy normal subjects at a dose of 6 mmol, but thiopronine and glutathione produced a significant hypotensive effect...

Redox imbalance is resulted from the destruction of balance between oxidants and antioxidants. The dominant oxidants are reactive oxygen species (ROS), which are involved in multiple cellular processes by physiologically transporting signal as a second messenger or pathologically oxidizing DNA, lipids, and proteins. Generally speaking, low concentration of ROS is indispensable for cell survival...

Oxidative damage of DNA caused by a variety of chemical and physical agents appears to be linked to cancer. However, it is becoming increasingly clear that endogenous generation of oxidants, such as hydroxyl radical and peroxynitrite, lead to oxidation of DNA, and this may cause cancer in individuals where no obvious exposure to chemical or physical agents known to be carcinogenic has occurred....

Synthesis of fullerene oxides[C70(O)n] (n=1~3 or n=1) by fullerene [C70] and several oxidants such as 3-chloroperoxy benzoic acid, chromium(VI) oxide, benzoyl peroxide, trichloroisocyanuric acid take place under microwave irradiation. The MALDI-TOF MS, UV-visible spectra and HPLC analysis confirmed that the products of fullerene oxidation are [C70(O)n] (n=1~3 or n=1). Keyword : A.Fullerene oxid...

We report the synthesis of novel ultralong core–shell Cu 2− x S nanowires (NWs). The NWs present high flexibility, stability to acids and oxidants low resistivity (6.9 × 10 −6 Ω m). They also exhibit promising performances as supercapacitors.

Background & Aim: The most common primary brain tumors of the central nervous system are gliomas. Among a number of different biomolecular events, a strong relation between oxidative stress pathways and the development of this cancer has been proved. Oxidative stress (OS) is the consequence of an imbalance between pro-oxidants and antioxidants towards pro-oxidants. The pro-oxidants cause lipid ...
