Lobsters have numerous adaptive specializations of the olfactory system that make them especially suitable model organisms for the study of olfaction. Recent work using genomics and physiological genomics to study the lobster olfactory organ extends the advantages of their use further. A subtracted cDNA library from the mature zone of the olfactory organ and 3 physiological genomics experiments...
بررسی اثر کادمیوم و نیکل بر الگوی تولید آلکالوئیدها در گیاه پروانش (Catharanthus roseus (L.) G. Don)
Tropical plant, Catharanthus roseus contains worthy alkaloids such as vinblastine and ajmalicine. Since amount and pattern of alkaloid production could be affected by different environmental conditions, the effect of two elements of cadmium and nickel were investigated. Plants in the greenhouse conditions using a chemically inert substrate were cultivated and in a complete randomized block desi...
The concentration of heavy metals in the environment is normally low. We here address whether using the development of isolated pond snail Radix auricularia eggs would provide a more sensitive endpoint and whether the gelatinous matrix of the egg mass surrounding the eggs indeed protects the snail embryos. In the present study, artificial removal of the gelatinous matrix of egg masses greatly i...
phytoremediation is a biological method by which plants are used to remove environmental pollution caused by toxic elements such as the accumulation of cadmium, copper, lead, chromium, etc. from soil. the arbuscular mycorrhizal fungi (amf) help the plant to increase uptake and translocation of low mobility nutrients and also micronutrients. in this research, arbuscular mycorrhizal inoculant was...
this investigation aimed to examine the protective function of vitamin e on rat bone marrow mesenchymal stem cells (mscs) treated with cadmium chloride. rat bone marrow mscs were extracted using flashing-out and cultured in dmem containing 10% fbs and 100 u/ml pen/strep. at the end of the third passage, cells were divided into 4 groups including control, cadmium chloride, cadmium chloride + vit...
Exposure to toxic metals has become an increasingly recognized source of illness worldwide. Both cadmium and arsenic are ubiquitous in the environment, and exposure through food and water as well as occupational sources can contribute to a well-defined spectrum of disease. The symptom picture of arsenic toxicity is characterized by dermal lesions, anemia, and an increased risk for cardiovascula...
Despite Euphorbia hirta L. ethnomedicinal benefits, very few studies have described the potential toxicity. The aim of the present study was to evaluate the in vivo toxicity of methanolic extracts of E. hirta. The acute and subchronic oral toxicity of E. hirta was evaluated in Sprague Dawley rats. The extract at a single dose of 5,000 mg/kg did not produce treatment related signs of toxicity or...
Developmental toxicity testing could greatly benefit from the availability of an in vitro alternative model based on the use of animal embryos that have better human-like physiology than the currently-used alternative models. These current models are insufficient, as extrapolation of the results can be challenging. Therefore, an in vitro bovine embryo culture system was used to expose individua...
