The synthesis, base-pairing properties and in vitro and in vivo characteristics of 5-methyl-isocytosine (isoC(Me) ) and isoguanine (isoG) nucleosides, incorporated in an HNA(h) (hexitol nucleic acid)-DNA(d) mosaic backbone, are described. The required h-isoG phosphoramidite was prepared by a selective deamination as a key step. As demonstrated by Tm measurements the hexitol sugar showed slightl...

Gold-thiol chemistry is widely used in nanotechnology but has not been exploited in optical-trapping experiments due to laser-induced ablation of gold. We circumvented this problem by using an array of gold nanoposts (r = 50-250 nm, h approximately 20 nm) that allowed for quantitative optical-trapping assays without direct irradiation of the gold. DNA was covalently attached to the gold via dit...

Background: Adequate dietary intake of Selenium (Se) with regard to crucial role in the body functions and prevention of risk of cancers is more important. According to growth of world populations and soil erode inadequate daily intake of Se is an noticeable man concerns. Selenium enriched yeast (Se-yeast) as a good food supplements of Se with high organic and bio-available form of Se which imi...

Selenium (Se) is an essential element for human and livestock health with antioxidant and anticancer effect. Although Se is not an essential element for plant growth,but improve the plant growth. A hydroponic experiment was conducted in the greenhouse of Isfahan University of Technology in winter of 1391. The completely randomized design was arranged. Se in four concentration 0, 2.5, 5 and 10 &...

This research was conducted with the purpose of appraising the effect of Selenium (Se) and/or amino acid fertilizers (AA) on improving growth, physiology, and biofortification of parsley grown under high EC condition. Plants were foliarly supplemented with four levels of Se (0, 25, 50, 100 mgl-1) and/or two concentrations of AA (0 and 0.2%) three times with a week interval. The significantly in...

Background : Selenium-73 (T 1/2 =7.1h) and Selenium-75 (T 1/2 =119.8d) are useful radioisotopes in many research fields. The wide ranges of applications of these radioisotopes arose great interest for their production. Simultaneous production of 73 Se and 75 Se is more cost-effective and less time-consuming. Materials and Methods : 73 As (p, 3n) 73 Se and 75 As (p,n) 75 Se reactions were determ...

Selenium (Se) is a beneficial element for plant but at high concentrations, it is toxic and causes in plant growth retardation. There is limited information about the effects of Se on salinity-induced damages on wheat. Therefore this study was carried out to investigate interaction of salinity and Se on root and shoot dry matter yield, activity of GPX, and concentrations and uptake of selected ...

The study was designed to investigate the effects of dietary Selenium-enriched radish sprouts (Se-RS), Vitamin E (Vit E), and Rhodobacter capsulatus (RC) on immunity, cholesterol concentration, and fatty acid composition in broiler meat. A total of 100 two-week-old male broiler chicks were randomly assigned into five dietary groups: I) Control; II) Se-RS (5 μg/kg Se-RS); III) Se-RS+RC (5 μg/kg ...

Selenium (Se) is an important microelement for plants and has been shown to improve growth under normal and stressed conditions. In this study, effect of Se and nano-selenium (N-Se) on hydroponically-grown tomato (Lycopersicum esculentum Mill. cv. ‘Halil’) on photosynthesis, antioxidant activity and total polyphenolic content was assessed. A factorial experiment with three temperatu...

Selenium (Se) at high concentrations can cause toxic effects in plants, whereas at low concentrations it enhances resistance to certain abiotic stresses. The possible mechanisms of the Se-enhanced tolerance of plants to salinity stress remain elusive. In this work, effect of Se supplementation at 0, 0.1, 1 and 10 mg l-1 sodium selenate was studied in Lallemantia iberica plants subjected to salt...
