13. Oxidative Damage and Antioxidant Response in Chenopodium murale L. Exposed to Elevated Levels of Zn
ABSTRACT Present study was carried out to investigate the effects of different Zn concentrations on growth and some antioxidant responses in Chenopodium murale L. The seeds were sown on the pots. 45-day plants were transferred to hydroponic solution containing 0.2 (control), 150, 300 and 600 µM Zn. The plants were harvested at 6 days after applying Zn treat

14. Laboratory evidence for the hematopoietic potential of Beta vulgaris leaf and stalk extract in a phenylhydrazine model of anemia
This study was designed to provide laboratory evidence supporting the hematopoietic effect of Beta vulgaris (beet) leaf aqueous extract in phenylhydrazine-induced anemia model in albino rats. Extraction of the leaves/stalks was done by maceration in 30% hydro-ethanol for 48 h. An intraperitoneal injection of 20 mg/kg phenylhydrazine was applied for two conse

15. Antioxidant response of cowpea co-inoculated with plant growth-promoting bacteria under salt stress
Abstract Soil salinity is an important abiotic stress worldwide, and salt-induced oxidative stress can have detrimental effects on the biological nitrogen fixation. We hypothesized that co-inoculation of cowpea plants with Bradyrhizobium and plant growth-promoting bacteria would minimize the deleterious effects of salt stress via the induction of enzymatic a

16. Yeast extract elicitation increases vinblastine and vincristine yield in protoplast derived tissues and plantlets in Catharanthus roseus
Abstract Catharanthus roseus (L.) G. Don, Apocynaceae, is an immensely important medicinal plant, produces a variety of anticancerous compounds. The yield of two most investigated alkaloids vinblastine and vincristine is unfortunately very low. A vast array of technologies including elicitation have recently been used to enrich Catharanthus alkaloid in cultu

17. Morphophysiological and biochemical alterations in Ricinus communis L. seeds submitted to cobalt60 gamma radiation
ABSTRACT This study aimed to evaluate the radiosensitivity of castor bean seeds after applications of different doses of Cobalt60 gamma radiation. Seeds were pre-soaked for 24 hours in distilled water and then irradiated with 50, 100, 150, and 200 Gy, except the control. Sowing was performed in trays, which contained soil as substrate and were maintained in

18. Phytoremediation of arsenic-contaminated water: the role of antioxidant metabolism of Azolla caroliniana Willd. (Salviniales)
ABSTRACT Phytoremediation has proven to be an efficient technology for removing arsenic (As) from water, but the plants used in this process need to be tolerant to the damage caused by As. The toxic effect of As on growth and functioning of the antioxidant system was studied in individual plants of Azolla caroliniana exposed to five concentrations of As (0.0

19. Soluble amino acid profile, mineral nutrient and carbohydrate content of maize kernels harvested from plants submitted to ascorbic acid seed priming
ABSTRACT Both the scientific community and society have shown interest in improving the content of amino acids, carbohydrates and mineral nutrients in maize because it represents an important staple food in many developing countries. Earlier studies demonstrated that the treatment of seeds using ascorbic acid (AsA-seed priming) enhanced soluble carbohydrates

20. Assessment of Genetic Fidelity of in vitro Raised Plants in Swertia chirayita through ISSR, RAPD analysis and Peroxidase Profiling during Organogenesis
ABSTRACT An efficient in vitro regeneration protocol for medicinally important herb Swertia chirayita was developed and the genetic fidelity was assessed using RAPD and ISSR markers. The best shoot regeneration was observed on MS basal supplemented with 1.0 mg/L Benzyl amino purine (BAP) in combination with Indole-3-acetic acid (IAA) (0.5 mg/L) that resulted

21. Measuring of the Genotoxic and Potential Antioxidant Effects of Essential Oil Obtained from Satureja Hortensis Against to Phaseolus Vulgaris
ABSTRACT It is known that, there are many ways for increasing the yield at the crops specially cereal products. Genetic manipulations and physiological interventions are the primary studies that aim to obtain products at high quality and amounts. It is known that, the usage of synthetic chemicals for physiological inverventions negatively affects organism. B

22. Bonding Effectiveness of Universal Adhesive to Intracoronal Bleached Dentin Treated with Sodium Ascorbate
Resumo Este estudo avaliou o efeito do protocolo restaurador empregando ascorbato de sódio na resistência ao cisalhamento do adesivo universal à dentina intracoronária clareada. Cento e vinte fragmentos de dentina bovina foram aleatoriamente divididos em doze grupos (n=10), de acordo com o procedimento clareador (clareados e não clareados) e protocolo r

23. Effects of alpha-tocopherol on fracture resistance after endodontic treatment, bleaching and restoration
Abstract This study evaluated the effects of 10% alphatocopherol on the fracture resistance of endodontically treated teeth subjected to tooth bleaching with hydrogen peroxide and immediately restored with composite resin. Fifty bovine incisors were selected, including 10 sound teeth that constituted the control group (G1 (C)). The remaining 40 teeth, which

24. Synthesis of 3-(1H-1,2,3-Triazol-1-yl)-2-(arylselanyl)pyridines by Copper-Catalyzed 1,3-Dipolar Cycloaddition of 2-(Arylselanyl)-3-azido-pyridines with Terminal Alkynes
We present here our results in the synthesis of eleven new 3-(1H-1,2,3-triazol-1-yl)-2-(arylselanyl)pyridines by copper-catalyzed azide-alkyne cycloaddition reactions. The reactions were performed in the presence of catalytic amount of copper(II) acetate and sodium ascorbate using a mixture of tetrahydrofuran/water (1:1) as solvent at room temperature in air
