Iost toxic diseases can be divided into those which result from consumption or exposure to toxic chemicals or poisonous plants. They can be prevented by limiting access to these chemicals and plants. Copper Toxicity, Causes— (a) excessive copper ingestion, (b) absence of sufficient molybdenum in diet, (c) injury to liver tissue from plant alkaloids enabling the liver to store excess copper, (d)...

CdTe solar cells were fabricated with five different concentrations of copper, including zero, used in backcontact formation. Room-temperature J-V curves showed progressive deterioration in fill factor with reduced copper. JSC and QE were similar for all Cu-levels. Capacitance measurement suggested enhanced intermixing at the back contact with copper present. Photocurrent mapping was much less ...

Salicylic acid (SA) plays a key role in plant disease resistance and hyper-sensitive cell death but is also implicated in hardening responses to abiotic stress. The aim of this study is to examine the effects of salicylic acid on the growth, eco-physiological and biochemical characteristics in Zinnia elegans plant exposed to copper stress. Effects of copper (Cu) on biomass, root length and shoo...

BACKGROUND: The early stage of Copper poisoning is difficult to be clinically diagnosed in sheep and has not been documented clearly yet. OBJECTIVES: To assess biomarkers in predicting early Copper poisoning in sheep, blood samples were collected from several groups of animals from a naturally Copper poisoning occurrence in an industrial region. METHODS: Animals were divided into four experimen...

GOAL, SCOPE AND BACKGROUND Elevated concentrations of copper in the environment result in accumulation of the metal in plants and cause an increase in reactive oxidative species (ROS). The first response to elevated amounts of ROS is increased levels of enzymatic and non-enzymatic antioxidants that reduce oxidative stress. The aim of our study was to evaluate the early stages of antioxidative r...

copper (cu) is an essential trace element involved in normal reproduction but its over-exposure may produce some detrimental effects. the aim of this study was to investigate the effects of purslane on copper sulfate poisoning on liver structures changes. twenty eight wistar rats were randomly allocated to four treatment groups. group i) control, group ii) copper sulfate (200 mg/kg bw were appl...

Wilson disease (WD) is characterized by the accumulation of copper arising from a mutation in the ATP7B gene. Penicillamine (PA) makes 10-50% of the patients with neurologic symptoms neurologically worse at the early stage of administration. The aim of this study was to determine how the copper metabolism changes and whether the change impairs the brain of toxic milk (tx) mice, an animal model ...

Weight specific oxygen consumption and heart rates were investigated in blue swimming crab, Portunus pelagicus to indicate the stress in response to increasing salinities (50, 75, 100 and 125%SW) and increasing copper concentration (0, 0.75, 1.5, 3 and 6 ppm copper) at temperature 25 degrees C. Oxygen consumption (micromol.g(-1).h(-1) was measured using closed system respirometer (Strathkelvin ...

The application of iron and copper in combination with Rhizobium was studied with on the growth of Vignamungo(L.).The Vignamungo(L.) seeds were grown in different concentrations (0, 30, 60 and 90ppm) of iron and copper individually in natural conditions. This study has shown that copper and iron metal ions have stimulatory effects on plant growth at low concentration but it turns toxic at high ...

Root growth and protective enzymes of Festuca arundinacea L. and Lolium perenne L. under Cu stress were investigated in a hydroponic experiment. Cu stress significantly inhibited root growth (root elongation and dry biomass) of both turfgrasses. Malondialdehyde (MDA) content in roots of both turfgrasses markedly increased under copper stress. In F. arundinacea root, superoxide dismutase (SOD) a...
