The objective of this study was to investigate the propensity of permethrin (PTN) to induce oxidative stress and changes in enzyme activities in liver of rainbow trout and its possible attenuation by vitamin C. Forty-eight fish were randomly assigned to 1 of 6 treatment groups and their livers were used for liver perfusion method: control (0 μgL-1 permethrin and 0 mgL-1 vitamin C), PTN-0.16 (0....

abstract gerbera is one of the most demanded plants in commercial cut flowers plants. optimizing the micro-propagation of new cultivars is therefore important. in this research “red explosion” cultivar was used and capitola (as explants) were directed to a modified solid murashigue and skoog medium with four concentration of tdz (0.25, 0.50, 0.75 and 1.00 mgl-1) for regeneration. three concentr...

an efficient method for producing doubled haploid plants of date palm ( phoenix dactylifera l.) was established using in vitro colchicine treatment of anthers. to this study male inflorescences were harvested in the appropriate developmental stage. separated anthers after one day cold (4°c) pretreatment, in uninucleate stage of microspore were transferred to the modified y 3 medium containing d...

conclusion st-vab and mgl-eb are reliable biopsy methods for microcalcifications. in proper indications, breast microcalcifications could be obtained by each method without missing diagnosis of breast cancer. objectives to evaluate the outcome of st-vab and mammography-guided localization and excisional biopsy (mgl-eb) for microcalcifications. patients and methods two radiologists retrospective...

Yolk-sac fry of Goldfish (Carassius auratus gibelio) were exposed to various concentrations of Al and pH for 3, 7 and 10 days. In this study number of dead fish, total length of larvae, yolk sac length, swimming activity, the number of gill cover movements and the number of heart beat was measured. The lowest and highest number of gill cover movements belong to the waters containing 50 mg L-1 o...

The present study was conducted to induce callus from different in vitro grown seedling explants of shoot, root and leaf segments in order to develop shoot buds and rooting from callus. The sterilized seeds were cultured on Murashige and Skoog medium, and then the explants were cultured from seedling and transferred to an MS medium supplemented with different concentrations of BAP, kinetin, NAA...

Compost tea has a lot of potential for sustainable agriculture. The suppressive effect compost on damping-off disease in beans (Phaseolus vulgaris), caused by Rhizoctonia solani, was investigated. physicochemical properties the tested showed presence dissolved solids (7070 mgL-1), organic matter (1280 nitrate (3840 and ammonium (90.0 mgL-1). concentrations phosphorus, potassium, calcium, magnes...

The aim of this study was to identify the variation of plankton communities in the Tortum Lake. Changes in phytoplankton and zooplankton communities in relation to the abiotic environment were analyzed using multivariate analysis. Water samples were taken monthly from three sampling points of the Tortum Lake between June 2012 and May 2013. Water temperature (5.28-23.05°C), dissolved oxygen (1.5...
