the main source of heavy metals in soil is the use of urban and industrial waste water, synthetic phosphate fertilizers, sludge from sewage treatment plants. most heavy metals accumulate in the top soil and in the long term, their increased concentration in the soil and accumulation in the plants. the quantity or level of absorption in plants, depends not only on the concentration levels of the...

this work summarized the results of a long term monitoring programme performed downstream on the morava river (czech republic). during this programme the total dissolved concentrations and bioavailable fraction of selected metals (zn, pb, ni, cu) were monitored. for the determination of bioavailable metals species, diffusive gradients in thin films technique (dgt) together with moss bags techn...

   Background & Objective:  Irisin is considered as a candidate to treat obesity and metabolic diseases. Therefore, the aim of this study was a systematic review and meta-analysis to define the effective modes of exercise on irisin concentration in adults.  Materials & Methods:  Google Scholar, PubMed, Medline, Scopus, Science Direct, and references lists of articles were searched until April ...

Heavy metals are among the most significant freshwater pollutants and pose severe threats to geographical biodiversity. Pollution by heavy metals such as Cd, Pb, etc. not only affects the productivity of crops, but also compromises the quality of the atmosphere and water bodies. By propagation through the food chain, this type of pollution also threatens the health and life of animals and human...

This study used hair and nails to biomonitor heavy metals (Pb, Cd, Cr and Cu) from geological source and exposure through regular fish consumption among children in Lake Victoria, Kenya. Concentration of Pb and Cu in water reflected anthropogenic pathways, while Cd and Cr reflected accumulation from the catchment basin. Higher concentration of heavy metals in the nails samples than the hair sam...

Over the past several years meditation practice has gained increasing attention as a non-pharmacological intervention to provide health related benefits, from promoting general wellness to alleviating the symptoms of a variety of medical conditions. However, the effects of meditation training on brain activity still need to be fully characterized. Sleep provides a unique approach to explore the...

background: this study aims to investigate the patterns of bioaccumulation and depuration of copper in the selected kidney and liver of capoeta fusca. methods: the fish were collected between september and november 2010 from a qanat in birjand. they were exposed to two types treatments with copper (0.25 and 0.75 mg/l) for a period of 41 days. the fish under study were exposed to the above-menti...

objective: successful bonding of a dental implant to bone, which was referred to as osseointegration by branemark has been well documented. however, long-term prognosis of an implant depends on adequate maintenance and long-term care. an effective maintenance program is required to preserve the health of peri-implant tissues. several techniques have been suggested for this purpose but it is not...
