Environmental pollutants act as risk factors for Alzheimer's disease (AD), mainly affecting the aging population. We investigated early manifestations of AD-like pathology by a mixture of arsenic (As), cadmium (Cd), and lead (Pb), reported to impair neurodevelopment. We treated rats with As+Cd+Pb at their concentrations detected in groundwater of India, ie, 0.38, 0.098, and 0.22 ppm or 10 times...

BACKGROUND Ipomoea aquatica (Convolvulaceae), an aquatic edible plant, is traditionally used against heavy metal toxicity in India. The current study intended to explore the protective role of edible (aqueous) extract of I. aquatica (AEIA) against experimentally induced Pb-intoxication. METHODS The cytoprotective role of AEIA was measured on mouse hepatocytes by cell viability assay followed ...

Concurrent exposure to cadmium (Cd) and lead (Pb) is prevalent in the environment, but information on long-term impacts of complex Cd–Pb herbivorous insects, especially at low doses, scant. We studied effects (4.06 mg/kg Cd 12.5 Pb) growth food utilization insect Spodoptera litura for 10 continuous generations. or Pb ingestion, excretion accumulation by different developmental stages was determ...

BACKGROUND Exposure to heavy metals in development of many diseases has been investigated previously, specially created by oxidative stress. The etiology of Rheumatoid arthritis (RA) is still not fully understood but oxidative stress created by heavy metals may have role in development of RA. The aim of present study was to compare serum level of heavy metals in RA and healthy control individua...

Background: Lead (Pb) is one of the most important environmental pollutants that affect the male reproductive system. The aim of this study was to investigate the protective effect of green tea extract on lead-induced oxidative stress, apoptosis and morphometric changes in male mouse epididymis. Materials and Methods: Forty adult male mice were randomly divided into four groups (n= 10), as foll...

Lead is a nonessential element that has a negative effect on plant growth and development. Plant symbiosis with arbuscular mycorrhizal fungi (AMF) in soils contaminated with heavy metals can affect growth of plant, nutrition and tolerance against heavy metals. In this study, the effect arbuscular mycorrhizal fungi Glomus intraradices on the growth, photosynthetic pigments, protein content, prol...

Stress-induced changes in the imprint and switching behavior of ~111!-oriented Pb(Zr,Ti)O3 ~PZT!-based capacitors have been studied using piezoresponse force microscopy. Visualization of polarization distribution and d33-loop measurements in individual 131.5-mm 2 capacitors before and after stress application, generated by substrate bending, provided direct experimental evidence of stress-induc...
