Variation Induced by Uranium Nitrate in Corn Smut and the Cultivated Mushroom.

Evaluation of 226Ra, 232Th, 137Cs and 40K “Agaricus Bisporus” Activity in Cultivated Edible Mushroom formed in Tehran Province- Iran

Introduction Natural and man made radioactive sources exist in our environment they can enter into our food chains. One of these is the soil-mushroom-human chain. High level doses of natural radiation can cause hazards to humans. Materials and Methods Samples of Agaricus bisporus cultivated edible mushroom in Tehran province- Iran were collected from 7 farms. Specific activity of 226Ra, 228Ra, ...

Diurnal variation in the nitrate content of parsley foliage

The diurnal fluctuation of nitrate concentration in the foliage of three parsley subspecies (plain-leafed, curly-leafed and turnip rooted parsley) cultivated in the spring and autumn of two consecutive years was examined. Nitrogen was applied at 30 (Control), 75, 150, 300 mg kg-1 in both years, but with the addition of 450 mg kg-1 in year 2. Harvest was carried out at 08:30, 12:30 and 17:30 on ...

Biogeochemical changes induced by uranyl nitrate in a uranium waste pile

Sodium bicarbonate protects uranium-induced acute nephrotoxicity through uranium-decorporation by urinary alkalinization in rats

To evaluate the effectiveness of sodium bicarbonate (SB) in removing uranium and protecting animals from uranium toxicity, we intramuscularly administered 1 mg/kg of uranyl nitrate to 8-wk-old male SD rats, and 20 min after administration of uranyl nitrate, the animals were given a single oral administration of SB at 0.1, 0.3 or 1 g/kg. The SB treatment at a dose of 0.3 g/kg or more raised the ...

Aflatoxin and Fumonisin in Corn (Zea mays) Infected by Common Smut Ustilago maydis

Abbas, H.K., Zablotowicz, R.M., Shier,W. T., Johnson, B. J., Phillips, N.A.,Weaver,M. A., Abel, C. A., and Bruns, H.A. 2015. Aflatoxin and fumonisin in corn (Zea mays) infected by common smut Ustilago maydis. Plant Dis. 99:1236-1240. Corn infected with Ustilago maydis (common smut) produces galls that are valued as a delicacy in some cultures. During a 4-year period, aflatoxin levels in asympto...
