BACKGROUND Whether infants regulate copper absorption and the potential effects of excess copper in early life remain poorly defined. OBJECTIVE The objective of the study was to assess copper retention, liver copper content, and liver function in infant rhesus monkeys fed infant formula containing 6.6 mg Cu/L. DESIGN From birth to 5 mo of age, infant rhesus monkeys were fed formula that was...

Plant growth and activity of peroxidases (POX) and phenylalanine ammonia-lyase (PAL) were investigated in seedlings of yellow lupine (Lupinus luteus L.) and soybean (Glycine max L.) treated with copper (25 mg/l) and an inhibitor of ethylene biosynthesis (CoCl 2 ). Both lupine and soybean plants stressed with an excess of copper exhibited a decrease in root length and fresh weight. In lupine pla...

Homeostatic systems for essential and non-essential metals create the cellular environments in which the correct metals are acquired by metalloproteins while the incorrect ones are somehow avoided. Cyanobacteria have metal requirements often absent from other bacteria; copper in thylakoidal plastocyanin, zinc in carboxysomal carbonic anhydrase, cobalt in cobalamin but magnesium in chlorophyll, ...

introduction: indian childhood cirrhosis is a chronic liver disease usually seen in paediatric age group and is unique to the indian subcontinent. the definitive causative factor for the disease is not found till now but excess copper ingestion has been associated with it.case presentation: an indian origin one and half year old premorbidly normal male child presented with history of gradual di...

Spectrophotometric studies are presented of the glycylglytine-copper(I1) [GG-Cu(II)] system in aqueous solution under conditions in which the ligand is present in great excess (up to 1000: 1). In highly basic solution (pH 12 to 13) the spectral absorption maximum changes with increasing ligand concentration from 640 to 540 rnp. The spectral data are interpreted in terms of an equilibrium betwee...
