To investigate the antioxidative response of glutathione metabolism in Urtica dioica L. to a cadmium induced oxidative stress, activities reductase (GR), glutathione-S-transferase (GST), and peroxidase (GSH-Px), content reduced (GSH) oxidized (GSSG) glutathione, lipid peroxidation (LPO), also accumulation Fe, Zn, Mn, Cu besides Cd were determined roots, stems, leaves plants exposed 0 (control), 0.045, 0.09 mM CdCl2 for 58 h. Whereas continuously increased all organs, decreased dependence on...

Abstract Here, the effects of previously characterized poly(HEMA-N-vinyl formamide) (PHEMA-NVF) cryogels on viability, surface morphology, total antioxidant-oxidant status, antioxidant enzyme activities and biochemical makeup Saccharomyces cerevisiae were investigated for first time. The viability cells released from PHEMA-NVF found to decrease dramatically up 23.96 ± 1.44% compared plain PHEMA cryogel as control group without NVF. Additionally, this caused blebbing holes cell surface....

In the present work, partitioning behavior of menadione-induced superoxide dismutase (SOD; EC 1.15.1.1), an antioxidant enzyme that has various applications in medical and cosmetic industries, from white rot fungus Phanerochaete chrysosporium been characterized on different types aqueous two-phase systems (ATPSs) (poly(ethylene glycol)/polypropylene glycol (PEG/PPG)-dextran, PEG-salt PPG-salt). combinations were found most optimal for purification SOD. The best partition conditions using...

Boron is one of the most important elements with its indisputable biological importance and widespread use. The studied derivatives boron element are boric acid salts. In this article, we searched effects lithium salt, metaborate, on enzymatic defense system, cell damage, surface morphology Saccharomyces cerevisiae BY4741 strain. It was found that while all concentrations showed toxicity against yeast, even highest concentration metaborate could not effectively inhibit viability. addition,...

In this study, it was focused on the synthesis of MgO nanoparticles by using dried jujube fruit extract through nontoxic and eco-friendly green method for first time. The thereby obtained were characterized UV–Vis spectroscopy, Fourier transform infrared X-ray diffraction (XRD) analysis, scanning electron microscopy (SEM) in combination with energy-dispersive spectroscopy (EDX), transmission (TEM). formation small-sized firstly confirmed maximum absorbance value at 320.3 nm. ATR-FTIR...

Boric acid and its less-known derivative lithium metaborate are inorganic acids used in a wide diverse array of industrial clinical applications. In particular, boric is accepted as natural antimicrobial agent due to activity on many different microbial species. We have examined the possible dependency metaborate-induced yeast toxicity deletion antioxidative CTT1, TRR2 GSH2 genes expressions certain important pro- anti-apoptotic genes. While investigated no function protection against...
