Introduction: Acrylamide (ACR) known as a neurotoxic agent in human and animals. Previous studies have been shown; fasudil improves neurological deficit and neuronal damage. In this study, the effect of fasudil, potent Rho-kinase inhibitor, on ACR-induced cytotoxicity was evaluated using PC12 cells as a suitable in vitro model. Materials and Methods: PC12 cells were exposed to different concent...

Abstract. The oxidative potential (OP) of particulate matter (PM) measures PM capability to potentially cause anti-oxidant imbalance. Due the wide range and complex mixture species in particulates, little is known about pollution sources most strongly contributing OP. A 1-year sampling PM10 (particles with an aerodynamic diameter below 10) was performed over different sites a medium-sized city ...

The wide-scale applications of zinc oxide (ZnO) nanoparticles (NPs) in photocatalysts, gas sensors, and cosmetics may cause toxicity to humans and environments. Therefore, the aim of the present study was to reduce the toxicity of ZnO NPs by coating them with a silica (SiO2) layer, which could be used in human applications, such as cosmetic preparations. The sol-gel method was used to synthesiz...

The widely used culinary vegetable, red cabbage (Brassica oleracea L. Var. capitata f. rubra), of the Brassicaceae family contains biologically potent anthocyanins and a myriad of antioxidants. Previous studies have shown that the pharmacological effects of red cabbage in vivo are redox-sensitive. The present study explored whether red cabbage modulates various histopathological and biochemical...

The EtOH extract from the rhizomes of Astilbe koreana (Saxifragaceae) exhibited potent antioxidant activity in our recent study. Since the oxidative stress is known to be involved in the inflammatory response after ultraviolet B (UVB) exposure, the ability of the A. koreana extract to inhibit UVB-induced prostaglandin E2 (PGE2) and nitric oxide (NO) production was examined. UVB irradiation (35 ...

Increased production of oxidants subsequent to phagocyte stimulation has been associated with tissue damage in lung inflammatory disorders. The overall oxidative burden of the lung may vary with inflammatory cell composition. Flow cytometry using three different dyes, dihydroethidium (DHE), dichlorofluorescein diacetate (DCFH-DA) and dihydrorhodamine 123 (DHR), all compounds that by interaction...

Determination of reactive oxygen species (ROS) in erythrocytes have been extensively studied due to its important pathophysiological role in many diseases. Also, studies on the potential of many antioxidants compounds are important to improve human healthy. This paper describes a simple and fast method to quantify ROS in erythrocytes with induction of oxidation and antioxidant protection. Tert-...

BACKGROUND Quinoline derivatives have diverse biological activities including anticancer activity. On the other hand, many sulfonamide derivatives exhibited good cytotoxic activity. Hybrids of both moieties may present novel anticancer agents. RESULTS Chloroquinoline incorporating a biologically active benzene-sulfonamide moieties 5-21 and diarylsulfone derivatives 22 and 23 were prepared usi...

-The clinical efficacy of anthracycline antineoplastic agents is limited by a high incidence of severe and usually irreversible cardiac toxicity, the cause of which remains controversial. In primary cultures of neonatal and adult rat ventricular myocytes, we found that daunorubicin, at concentrations </=1 micromol/L, induced myocyte programmed cell death within 24 hours, as defined by several c...
