AIMS To evaluate the effects of hydrogen peroxide exposure on the survival and proliferation of cultured lens epithelial cells. METHODS TOTL-86 cells, a line of rabbit lens epithelial cells, were used. The survival and proliferation of TOTL-86 cells were quantified by a rapid colorimetric assay (MTT assay). To determine the effects of hydrogen peroxide, TOTL-86 cells were exposed to different...

Abstract Recently, interest in on-site heat generation has increased due to injection of thermochemical fluids as a complex effect on well productivity. The method treatment with H 2 O while restoring and increasing the filtration characteristics bottomhole formation zone is relatively new insufficiently studied technology. article discusses key factors affecting exothermic decomposition this f...

Wet hydrogen peroxide catalytic oxidation (WHPCO) is one of the most important industrially applicable advanced oxidation processes (AOPs) for the decomposition of organic pollutants in water. It is demonstrated that manganese functionalized silicate nanoparticles with interparticle porosity act as a superior Fenton-type nanocatalyst in WHPCO as they can decompose 80% of a test organic compound...

UNLABELLED Overproduction of free radicals in ageing tissues induces nitro-oxidative stress, which has been implicated in the functional decline of the cardiovascular system at old age. Toxic oxidants like hydrogen peroxide or peroxynitrite damage proteins and DNA and activate several pathways causing tissue injury, including the poly(ADP-ribose) polymerase (PARP) pathway. AIM First, we teste...

The decomposition of sulfopropyl sulfonate ~SPS, 4,5-dithiaoctane-1,8-disulfonic acid! in acid copper electroplating chemistries was studied using scanning electrochemical microscopy ~SECM!, UV-visible spectroscopy, high pressure liquid chromatography, liquid chromatography mass spectrometry, and electron spin resonance. The primary decomposition product is proposed to be the thiolsulfonate of ...
