Background: Intra uterine devices (IUDs) are among the most commonly used contraception methods around the world. The most common form of IUDs used in Iran, is IUD Copper T-380A. As recently there is great emphasis on the role of blood zinc levels on general health conditions, this study was performed to assess the effects of IUD T-380-A insertion on zinc and also copper serum levels. Materials...

Background and Aims: Giardia lamblia infection is a common cause of food and water-borne diarrhea in non-sanitary communities. Infections are common in children, particularly in child-care centers, backpackers, travelers, and homosexuals. Zinc is necessary for the immune system functions. Zinc deficiency is associated with acute diarrhea. Copper is essential for the production of red blood cell...

background: pemphigus vulgaris is a life threatening, blistering skin disease. it is an autoimmune abnormality. due to involvement of oral cavity and pharynx, patients are at risk of nutrients deficiency. the aim of this study was to evaluate the status of selenium, copper, and zinc in these patients. methods: in a case-control study, 43 newly diagnosed pemphigus vulgaris patients were compared...

Among the various existing metals, zinc and copper are predominant metals in several effluents from industries such as electroplating, plastics production mining. Technical methods have been applied treatment of containing including chemical removal, adsorption, ion exchange, membrane technologies electrochemistry. However, it is necessary to develop that minimize costs increase quality while r...

BACKGROUND Iron supplements are commonly recommended for infants but were suggested to inhibit zinc and copper absorption. OBJECTIVE The objective of this study was to investigate potential effects of iron supplementation, infant age, and mineral status on zinc and copper absorption in infants at 6 and 9 mo of age. DESIGN Twenty-five healthy breastfed term infants were recruited from a larg...

Background: Seborrheic dermatitis is a common chronic relapsing inflammatory skin disease with unknown etiology. Using zinc and selenium supplements have shown some relieving effects on the symptoms of the disease. The present study was conducted to determine the relationship between serum selenium, zinc, and copper levels with seborrheic dermatitis. Methods: A prospective case-control study wa...

apart from the breast milk, infant formula and baby weaning food have a special role in infant diet. infants and young children are very susceptible to amount of trace elements. copper and zinc are two elements that add in infant food. lead and cadmium are heavy metals that enter to food chain unavoidably. dpasv is a benefit and applicable method for measurement of trace elements in food produc...

Zinc and copper are essential trace elements. Dyshomeostasis in these two metals has been observed in Alzheimer's disease, which causes profound cognitive impairment. Insulin therapy has been shown to enhance cognitive performance; however, recent data suggest that this effect may be at least in part due to the inclusion of zinc in the insulin formulation used. Zinc plays a key role in regulati...

The effect of chronic exposure (35 days) to sub-lethal concentrations of copper (17-212 ppb) and zinc (41-525 ppb) on growth of Farfantepenaeus paulensis postlarvae 17 days old (PL(17)) was analysed. The effects of acute exposure of PL(17) to the same metal on food ingestion and oxygen consumption were also evaluated. Studies were performed using copper and zinc singly, and in a mixture of equi...

A method for the speciation of zinc and copper binding with proteins in human serum was explored by chelating resin (Chelex-100) pre-treatment and inductively coupled plasma mass spectrometry (ICP-MS). It was shown by a SEC (size-exclusion chromatography)-ICP-MS system that albumin-zinc and albumin-copper (loosely-bound species) could be selectively removed from serum by adsorption on the Chele...
