the present study was designed to investigate the protective effect of ethanol extracts from lindera coreana leaves (lce) on uvb-induced oxidative stress in hacat keratinocytes. the hacat cells were pretreated with lce for 24 h and then exposed to uvb (20 mj/cm2) for 2 h. uvb significantly decreased the cell viability (p<0.05). lce did not exhibit significantly cytotoxic effects and increased t...
background: diabetes is considered as one of the most common chronic disease. studies show that diabetes decreases the activity of antioxidant enzymes. the purpose of this study was to examine the effect of the alcoholic extract of juglans regia leave on brain antioxidant enzymes in streptozotocin-induced diabetic rats. materials and methods: in this study, adult male wistar rats (n=40, weight ...
The aim of the present study was to determine antioxidant defence mechanisms in the rat and Hymenolepis diminuta after long-term infestation. We determined levels of oxidative stress markers, and activity of antioxidant enzymes in the rat small intestine and in particular parts of H. diminuta. Observed changes in antioxidant enzymes activity in H. diminuta and the rat intestine indicate the def...
background: there are studies that indicated dyshomeostasis of oxidant/antioxidant and trace elements in breast cancer patients, but the data regarding the status of these parameters in various stages of breast cancer are limited. the aim of this study was to highlight the status of these biochemical factors in various stages of breast cancer. methods: fifty-eight breast cancers patients partic...
this study was performed to investigate the effect of putrescine and spermine on some physiological and biochemical characteristics and antioxidant enzymes activity of peach (prunus persica cv. alberta) and almond (prunus dulcis cv. rabi) seedlings under water deficit. the first factor was water regime at two levels (80% or 50% of soil available water), and the second factor was polyamine treat...
Hesperetin (Hst) is a well-known bioflavonoid, has low bioavailability. Hesperetin nanoparticles (Nano-Hst) enhance its bioavailability. Nano-Hst were not explored for their potential therapeutic activities in Alzheimer’s disease (AD). Hence, the present study was performed to evaluate the protective effect of Nano-Hst in comparison to free Hesperetin on against intracerebroventricular in...
BACKGROUND Diabetes mellitus is a metabolic disorder characterized by increased production of free radicals and oxidative stress. The aim of this study was to evaluate the activity of antioxidant enzymes, superoxide dismutase (SOD), glutathione reductase (GR), and glutathione peroxide (GSH-PX) in type 2 diabetic patients compared with healthy subjects. METHODS This cross-sectional study was c...
peppermint (mentha piperita l.), a herbaceous and perennial species whichis produced mainly for the medicine and food. the peppermint plants were initiated from 10 cm-long rhizome cuttings followed by transferring into pots. the 48 h-treated plants with methyl jasmonate (mj) concentrations (0, 0.1, 0.5 mm) were assessed for their total soluble proteins, malondialdehyde (mda), chlorophylls a, b ...
Unfavorable storage conditions, especially relatively high environment humidity and high storage temperature greatly affect the quality of corn seeds. The effects of temperature, environment moisture and length of storage on six maize hybrids were examined. For the purpose of investigating germination traits, total soluble proteins, leakage electrolytes and the activity of antioxidant enzymes i...
background: diabetes is a major cause of death. oxidative stress mainly caused by hyperglycemia is the primary reason of related complications. omega-3 fatty acids are prescribed in diabetes but the effect on antioxidant defense is controversial. this study investigated effects of omega-3 supplementation on antioxidant enzymes activity in type 2 diabetic patients. methods: a randomized, placebo...
