this research was conducted to evaluate the effects of 1-mcp and ethylene on extending the display quality and increasing vase life of cut carnation flowers in a completely randomized design with three replicationsat the laboratory of the postharvest physiology, tarbiat modares universityin 2014. first, cut flowers were treated with 0, 0.5, 1 and 1.5 µl l-1 of 1-mcp for 24 h and then exposed to...
background: the rosemary extract (re) possesses various antioxidant, cytoprotective and cognition-improving bioactivities. in this study, we postulated which doses of re have a more effect on the hippocampus of middle-aged rats. methods : in this experimental study, thirty-two middle-aged male wistar rats were fed by different doses (50,100 and 200 mg/kg/day) of re (containing 40% carnosic ac...
Cell culture data indicate that quercetin and catechin may affect the activity of phase II and antioxidant enzymes. However, little is known about the impact of dietary flavonoids in vivo. Therefore, the present study aimed to investigate the in vivo effects of the flavonoids quercetin and catechin on mRNA and activity levels of phase II enzymes glutathione-S transferase (GST) and NAD(P)H quino...
Woad (Isatis cappadocica Desv.) is a herbal plant, native to central and western Asia and from Brassicaceae family. In this research, we have investigated the effects of different irrigation levels on plant morphological and physiological attributes including canopy area, roots and shoots dry and fresh weight, roots length, proline concentration, shoots soluble carbohydrates content and antioxi...
salinity is a major limiting factor for plant growth and development. to evaluate the impact of p5cs gene expression under in vitro salt stress condition, transgenic tobacco (nicotiana plumbaginifolia) carrying p5cs gene and non-transgenic plants were treated with 0, 100, 150, 200 or 250 mm nacl for 28 days. proline content, lipid peroxidation and the activity of some antioxidant enzymes after ...
This study evaluated the acute effect of the administration of coffee brew in the activity of phase II antioxidant enzymes in the hepatic tissue of rats. A single dose of this beverage increased the activity of the enzymes SOD, CAT, and GPx; the maximum increase occurred 1 h after administration (19.1, 22.1, and 25.1%, respectively). These changes were statistically significant (p < 0.05), the ...
the present study was designed to investigate the immunomodulatory activity of the ethanolic extract of tinospora cordifolia (family: menispermaceae)stem (climbing shrub, mango plant) at cellular level. for antioxidant study, the liver mitochondria were separated and the concentration of enzymes like lipid peroxidation (lpo), reduced glutathione (gsh), catalase (cat) and superoxide dismutase (s...
Few studies are focused on the antioxidant status and its changes in anorexia nervosa (AN). Based on the hypothesis that renutrition improves that status, the aim was to determine the plasma antioxidant status and the antioxidant enzymes activity at the beginning of a personalized nutritional program (T0) and after recovering normal body mass index (BMI) (T1). The relationship between changes i...
BACKGROUND It has been reported that higher levels of oxidative stress and inflammation play a key role in the progression of hepatocellular carcinoma (HCC) after surgery. Coenzyme Q10 is an endogenous lipid-soluble antioxidant. To date, no intervention study has investigated coenzyme Q10 supplementation in HCC patients after surgery. The purpose of this study was to investigate oxidative stres...
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 ...
