helicobacter pylori infection leads to different clinical and pathological outcomes in humans, including chronic gastritis and gastric neoplasia. it has been demonstrated that oxidative stress associated with inflammation plays an important role in gastric carcinogenesis. to evaluate the oxidative stress in h. pylori infection we studied the gastric juice levels of nitric oxide and the activiti...

Abstract The present study evaluated the potential of carrot ( Daucus carota L.) leaf, a non-edible part carrots, which are among most consumed vegetables worldwide. antioxidant activities 70% ethanol extract (EEC) and hot water (HEC) leaves were compared. results revealed that total polyphenol content, flavonoid DPPH ABTS radical scavenging higher in EEC than HEC. Both extracts protected cells...

A ratiometric fluorescent probe for hypoxanthine (Hx) detection was established based on the mimic enzyme and fluorescence characteristics of cobalt-doped graphite-phase carbon nitride (Co doped g-C3N4). In addition to emitting strong fluorescence, peroxidase activity Co g-C3N4 can catalyze reaction O-phenylenediamine H2O2 produc...
