Abstract Wild oat is a herbicide resistance-prone global weed species that causes significant economic losses in dryland and horticultural agriculture. As result, there has been research effort to control this species. A major impediment the seed coat-mediated dormancy of wild oat, which requires labor-intensive incision or puncturing coat initiate germination. This study defines most efficient...

In iron-replete cells the posttranscriptional regulator IRP2 undergoes ubiquitination and proteasomal degradation. A similar response occurs in cells exposed to sodium nitroprusside (SNP), an NO-releasing drug. It has been proposed that nitroprusside ([Fe(CN)5NO]2-) fails to donate iron into cells and that it promotes IRP2 degradation via S nitrosylation at C178. This residue is located within ...

The cardiovascular and acid-base changes following equivalent i.v. bolus doses of sodium nitroprusside (SNP) and potassium cyanide (KCN) have been studied in two groups of anaesthetized dogs. In a third group, the metabolic changes produced by i.v. infusion of SNP 1.5 mg kg-1 at a constant rate over 1 h have been studied. In contrast to a decrease in arterial pressure following SNP, hypertensio...

To find the protective role of exogenous nitric oxide (NO) on salinity-stressed rice seedlings, a CRD-based factorial experiment with three replications was conducted in Agronomy Laboratory of the Faculty of Agricultural Sciences, University of Guilan, in 2012. The experimental design consisted of healthy and vigorous seedlings of two rice cultivars, Khazar and Goohar, the last already known as...

Curcumin, a polyphenolic compound has several pharmacological activities, such as anticancer, anti-inflammatory and antioxidant effects. However, curcumin shows poor oral bioavailability. The purpose of this study was to investigate the protective effects of highly bioavailable curcumin, Theracurmin(®), and curcumin, against sodium nitroprusside (SNP)-induced oxidative damage in mice brain. Int...

Abstract: Nitric oxide (NO) can act in biochemical pathways of the germination process; however, there is little information about how it acts on performance pea seeds. The aim this study was to evaluate physiological and effects NO seed vigor. Pea seeds cv. Itapuã 600 obtained from three lots with different levels quality were sown a substrate moistened water (control) or sodium nitroprusside ...

Photoinduced linkage isomers (PLI) of the nitrosyl ligand in single crystals Na2[Fe(CN)5NO] ⋅ 2H2O (SNP, sodium nitroprusside) have been studied by X-ray absorption spectroscopy (XAS) at low temperatures, using a cryostat allowing in-situ polarized LASER irradiation and XAS measurements. In XANES (X-ray near edge structure) region significant modification pre-edge peak intensities is observed a...

The effects of sodium nitroprusside (SNP) in rat cerebellar granular cell culture were investigated in the present study. All doses of the SNP (10, 25, 50, 100, 250, 500 microM) were able to induce cell death compared with control values (p < 0.001 for all groups tested). Interestingly enough, a nonlinear dose-response curve was obtained for SNP-induced neurotoxicity. We also investigated the p...

Soil lead (Pb) contamination is a major environmental and public health risk. Switchgrass (Panicum virgatum), second-generation biofuel crop, potentially useful for the long-term phytoremediation phytoextraction of Pb contaminated soils. We evaluated efficacy coordinated foliar application plant growth regulators soil fungicide chelator in order to optimize phytoextraction. Plants were grown cu...
