in order to study the effect of vermicompost containing copper oxide and zinc oxide nanoparticles on was beans, in an experiment factorial were done based on a randomized complete block design in three replications. the experiment treatment were as follows: nanoparticles in 4 levels (0, 0.4, 0.8 and 1.2 g/kg weight of substrate), vermicompost in 3 levels (2.5, 5 and 7.5 g/kg-1 weight of substra...

Metallothionein was purified under anaerobic conditions from livers of human fetuses ranging from 19 weeks gestational age to term. Homogeneous metallothionein obtained in the absence of reducing agents from the soluble fraction of the tissue which contained 24% and 85% of the total liver copper and zinc, respectively, had less than 1 g atom of copper and about 3.1 g atoms of zinc/mol. Extracti...

BACKGROUND Alzheimer disease (AD) patients are at risk of nutritional insufficiencies because of physiological and psychological factors. Nutritional compounds are postulated to play a role in the pathophysiological processes that are affected in AD. We here provide the first systematic review and meta-analysis that compares plasma levels of micronutrients and fatty acids in AD patients to thos...

A three-dimensional, porous electrode composed of reticulated vitreous carbon (RVC) has been examined for the selective removal of metals by electrodeposition from single and multi-component solutions. A three-stage system was envisioned where each metal from a ternary mixture could be selectively removed in each stage. Single and multi-component solutions of copper, nickel, zinc and silver wer...

Sequential changes in albumin, transferrin, alpha 1-acid glycoprotein, C reactive protein, fibrinogen, copper, iron, and zinc in plasma up to 24 h after hysterectomy were measured. No increases in the concentrations of the acute phase proteins alpha 1-acid glycoprotein, C reactive protein, and fibrinogen were observed until 6 h after the skin incision. These increases were preceded by significa...

Breast milk provides adequate nutrients during the first 6 months of life. However, there are some reports of zinc deficiency in breastfed infants. This study was conducted to determine the prevalence of zinc deficiency in infants aged 4-6 months and the associated factors. Healthy infants aged 4-6 months and their mothers were enrolled. They were classified by feeding types as breastfed (BF), ...

OBJECTIVE To evaluate the impact of 4 months of daily zinc supplementation on the incidence of severe and recurrent diarrhea in children 6 to 30 months of age. METHODS A double-blind, randomized, placebo-controlled trial was conducted on children who were identified by a door-to-door survey to be aged 6 to 30 months and residing in the urban slum of Dakshinpuri, New Delhi. They were randomize...

Cell signaling relies extensively on dynamic pools of redox-inactive metal ions such as sodium, potassium, calcium and zinc, but their redox-active transition metal counterparts such as copper and iron have been studied primarily as static enzyme cofactors. Here we report that copper is an endogenous regulator of lipolysis, the breakdown of fat, which is an essential process in maintaining body...

In parts of Canada including Newfoundland and Labrador and among Aboriginal peoples, infants still consume evaporated milk (EM) formulas for cultural and economic reasons. At 3 and 6 months, full-term infants fed EM (n = 30) received low intakes of iron, thiamine, selenium and had higher weight velocity than breastfed (BF, n = 29) infants. EM infants had greater anemia, lowered transketolase ac...

The aim of this work was to investigate whether Cu, alone or in combination with Mo, reduces the Se status of sheep. Thirty-six Hampshire ewes were separated prior to mating into four treatment groups of nine sheep each. The four groups consisted of 1) basal (alfalfa hay or legume-grass low-moisture silage, corn, oats), 2) basal plus 10 mg Cu/kg diet, 3) basal plus 10 mg Mo/kg and 4) basal plus...
