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...

a high percentage of world copper production is obtained from porphyry copper reserves, these reserves are characterized by: very high tonnage, greater horizontal dimensions than vertical, association with stock like intrusion masses, dispersed minerals in the porphyry mass and in its neighbor rocks, intense sericitization and inplace silicification. the porphyry coppers are concentrated by flo...

This research analyses the longitudinal relationships between household food insecurity (very low and low food security) experiences and children's consumption (servings/week) of fruit, green salad, carrots, potatoes, and other types of vegetables. Using a panel of 5,670 children aged 10-13 years who were first observed in spring 2004 and then again in spring 2007 at age 13-16 years, the main f...

OBJECTIVES To examine the association of timing of introduction and frequency of fruit and vegetable intake during infancy with frequency of fruit and vegetable intake at age 6 years in a cohort of US children. METHODS We analyzed data on fruit and vegetable intake during late infancy, age of fruit and vegetable introduction, and frequency of fruit and vegetable intake at 6 years from the Inf...

This study reports the modeling of three categories of ineffective vegetable parenting practices (IVPP) separately (responsive, structure, and control vegetable parenting practices). An internet survey was employed for a cross sectional assessment of parenting practices and cognitive-emotional variables. Parents (n=307) of preschool children (3-5 years old) were recruited through announcements ...

introduction: there have been many reports and papers on deficient, normal and high levels of copper in patients with thalassemia major. the aim of this study is to evaluate copper status in a series of more than 300 patients with thalassemia major and determine the degree of copper deficiency or excess. methods: three hundred and seventy patients with thalassemia major over 5 years of age were...

background: the aim of this study was to evaluate copper status in women with preeclampsia. materials and methods: sixty preeclamptic, sixty normotensive pregnant and sixty healthy nonpregnant women were enrolled in a cross sectional study. the 24-hour urine copper was compared among the women. results: there was significant difference in the copper concentration of 24-hour urine among the thre...

Antioxidants are substances that protect cells from the damages caused by free radicals. Fruit and vegetables rich in antioxidants provide important sources of antioxidants. While quest for an antioxidant supplement is ongoing, this study investigated vitamins minerals composition fresh carrot-cabbage juice. Antioxidant compositions juice were determined standard methods using spectrophotometry...

background: it is well established that oxidative modification of low density lipoprotein (ldl) plays a causal role in human atherogenesis and the risk of atherosclerosis is increased in patients with diabetes mellitus. we examined the in vitro effect of glucose on native and glycated ldl oxidation using copper ion dependent oxidation system. methods: in this study, ldl was isolated from plasma...

the thermal decomposition of 86 % vinyl chloride 14 % vinyl acetate copolymer wasstudied by the conductometry technique in the presence of nitrogen. the kinetics of stability andthermal degradation of vinyl chloride- co- vinyl acetate (pvc- co- pvac) copolymer withcopper, copper oxide and tricalcium dicitrate (st) were investigated at various temperatures (150-180 oc ) in solution. the rate coe...
