introduction   heavy metal contamination has disastrous effects on plant productivity and threatens human and animal health. among metals, cadmium (cd) is commonly released into the environment from industrial processes. cd is known to cause cellular damage in plants by producing oxidative stress via the over-production of reactive oxygen species (ros). to combat oxidative damage, plants have d...

introduction: oral lichen planus (olp) is a common mucocutanous disorder with unknown etiology. while current data suggest that oral lichen planus is a cell-mediated autoimmune disease, it might be associated to s+100, cd+4 and cd+8 cells. because of differential diagnosis of olp and oral lichenoid lesion (oll) is usually difficult this study was designed to compare any probable immunohistochem...

Background: Cadmium (Cd) is a heavy metal that is widely utilized in industries and contaminates soil and groundwater. There are several environmental problems related to cadmium, therefore, the technical and economic methods of removing Cd are of great importance. So this study was conducted to evaluate the efficiency of a type of plant to remove the Cd from aqueous environments. Methods: In t...

abstract lettuce is one of the best accumulators of heavy metals and nitrate between leafy vegetables. through this research, it was tried to decreased cadmium absorption with humic acid (ha) and studies the effect of ha on the accumulation and metabolism of nitrate. plants were grown in the peat/perlite and irrigated with hoagland solution with addition of cadmium (2 and 4 mg l -1) and ha (100...

oxidative stress has been identified as a crucial factor leading to male infertility largely due to peroxidativedamage to the sperm cell membrane. cadmium (cd) is a widespread environmental pollutant and oneof the well-known reproductive toxicants. because of its long biological half-life (10–30 years), cdaccumulates in the biological systems. the present study was designed to assess the concen...

measurement of availability and mobility of heavy metals in river sediments is required in order to understand the behavior of these metals and to prevent potential toxic hazards. leaching column experiments were conducted for four sediment samples to determine the degree of mobility and the distribution of zn, cd, ni, cu, and pb because of an application of spiked heavy metals in sediments. se...

Application of strategies inducing a heavy metal tolerant turfgrass is necessary for cultivation management. Water and soil contamination with heavy metals is an increasing concern for the human and environment health. This study was conducted to evaluate the mitigation of environmental Cd toxicity through landscape turfgrasses as affected by two arbuscular mycorrhizal fungi (AMF) species and t...

background: celiac disease (cd) may be misdiagnosed as irritable bowel syndrome (ibs) resulting in long delays in diagnosing cd. there are contradictory reports on the association of cd with ibs.appropriateness of screening all patients with ibs for cd and how to screen them are still under question. materials and methods: in a cross-sectional study, 328 ibs patients (rome ii) referred to the p...
