There has been much research into autism or autistic spectrum disorder (ASD) and room for considerable conjecture regarding the etiology of these disorders remain. ASD is marked by a complex interaction between environmental factors and genetic predisposition, including epistasis. This manuscript argues that changes in oxidative metabolism, thiamine homeostasis, heavy metal deposition and cellu...

This paper reviews the application of fuzzy theory and its combination with artificial neural-network technology for remote sensing information extraction. A dynamic fuzzy neural-network model is presented for crop heavy metal stress level assessment based on MODIS data. Hyperspectral vegetation indices, including NDVI, EVI and NDVIg, were used as input variables in this model for the purpose o...

Heavy metals such as Cu and Zn are essential for normal plant growth, although elevated concentrations of both essential and non-essential metals can result in growth inhibition and toxicity symptoms. Plants possess a range of potential cellular mechanisms that may be involved in the detoxification of heavy metals and thus tolerance to metal stress. These include roles for the following: for my...

Specific plants can remove heavy metals from the soil and contribute to pollution remediation in cropping systems. Determining the level of highest heavy metals that a super-accumulator crop can withstand without reducing its yield is important for management. The objective of this study was to investigate the heavy metal-removing capacity of purslane by studying different stress criteria and b...

Plants, in general, are put to various kinds of stress, biotic and abiotic, both natural and manmade. Infestation by insect pests and diseases, and extreme conditions such as salinity, temperature, etc., as well as heavy metal contamination affect their growth performance. Here, we studied the impact of salinity and heavy metal pollution on the growth performance of Indian Mustard Brassica junc...

this study at first level focused on definitions and descriptions of  some landfills and landfills sites all around the world and  survey on how important they are for regional governments and responsible in duty  as a very important responsibility for locals and their health. at the second level we had a look on heavy metals concentration which are by many definitions as follows: lead, nickel,...

Metal tolerance proteins (MTPs) are a gene family of cation efflux transporters that occur widely in plants and might serve an essential role in metal homeostasis and tolerance. Our research describes the identification, characterization, and localization of OsMTP11, a member of the MTP family from rice. OsMTP11 was expressed constitutively and universally in different tissues in rice plant. He...

The environmental risk of heavy metal pollution is pronounced in soils adjacent to large industrial complexes. It is important to investigate the functioning of soil microorganisms in ecosystems exposed to long-term contamination by heavy metals. We studied the potential effects of heavy metals on microbial biomass, activity, and community composition in soil near a copper smelter in China. The...
