Copper supplementation and monocyte function in growing beef calves
The effect of dietary copper (Cu) supplementation with Cu-Sulfate (CuSO₄) or Cu-Lysine (CuLy) on Cu status and bovine monocyte function was evaluated through a series of experiments. Initially, two in vitro techniques, immunomagnetic (IM) and culture flask adherence (CF), were compared for …

Evaluation of a copper lysine complex and copper sulfate in weanling and finishing pigs, and the effect of copper supplementation on circulating growth hormone and IGF-1 levels
The objectives of this research were 1) to evaluate CuS0₄ and a CU lysine complex (CuLys) as growth promotants for weanling pigs, 2) to assess the effects of feeding growth stimulating levels of Cu from both sources on dry matter digestibility (DMO) and mineral balance of finishing pigs, and 3) to …

Diagnosis, epidemiology and immunologic consequences of copper deficiency in calves
Copper is an essential micronutrient. Copper deficiency has been associated with disease states that decrease commercial beef production. Clinical manifestations of copper disease include anemia, diarrhea, long bone fractures, generalized ill-thrift, and decreased fertility. Recent studies have …

The influence of maternal nicotine exposure on development lung as gas exchanger: the protective effect of copper
… is catalysed by lysyl oxidase, an extracellular, copper dependent en4rmq from its soluble to its insoluble state. It is suggested that lesions occur in lturgs exposed to nicotine because of a decrease in lung copper content, which will, in turn, cause decreased lysyl oxidase activity. The aim of …

Eimeria acervulina infection and amino acid nutrition in broiler chickens
… In Experiment 2, the effects of supplementing copper, which can influence nutrient utilization, in diets of varying in AA density (low and high) on growth performance, apparent metabolizable energy, nutrient digestibility, and plasma carotenoids were evaluated in broiler chicks infected with E. …

An investigation into the effect of maternal exposure to nicotine and copper on neonatal lung development
… phase of rapid alveolarisation and, 2) whether copper supplementation (1mg/kg BW/day) will prevent the adverse effects of maternal nicotine exposure, on lung development in the offspring. The latter aim is based on studies in our laboratory which suggested that nicotine may impair lysyl oxidase …

Copper status in multiple trauma patients: measurement of copper balance, serum copper and ceruloplasmin
Changes in copper metabolism have been reported in both thermal injury and skeletal trauma; data regarding copper status in multiple trauma patients (MTP) are nonexistent. Hypercatabolism following multiple trauma may increase copper utilization, deplete copper stores and compromise cuproenzyme …

Characterization of Drosophila Ctr1a: New Roles for Ctr1 Proteins and Copper in Physiology and Cell Signaling Pathways
<p>Copper is an essential trace element required by all aerobic organisms as a co-factor for enzymes involved in normal growth, development and physiology. Ctr1 proteins are members of a highly conserved family of copper importers responsible for copper uptake across the plasma membrane. Mice …
