We report the case of a 56-year-old white man who presented at the Emergency Department for evaluation of dark-red urine. Rapid development of acute renal failure and haemolytic anaemia initially elicited the hypothesis of a haemolytic-uremic syndrome. A previous exposure to a gas mixture containing arsenic and copper was later recognized as the probable aetiology while other differential diagn...

Palladium-copper alloys continue to be of interest for hydrogen membrane applications because of their high catalytic activity for hydrogen dissociation, high hydrogen permeability, robustness, and degradation resistance in the presence of sulfur-containing compounds. This sulfur tolerance makes these alloys attractive for membrane applications where sulfur compounds are likely to be present, s...

copper (cu) is an essential trace element involved in normal reproduction but its over-exposure may produce some detrimental effects. the aim of this study was to investigate the effects of purslane on copper sulfate poisoning on liver structures changes. twenty eight wistar rats were randomly allocated to four treatment groups. group i) control, group ii) copper sulfate (200 mg/kg bw were appl...

Nutritional immunity is a process whereby an infected host manipulates essential micronutrients to defend against an invading pathogen. We reveal a dynamic aspect of nutritional immunity during infection that involves copper assimilation. Using a combination of laser ablation inductively coupled mass spectrometry (LA-ICP MS) and metal mapping, immunohistochemistry, and gene expression profiling...

held by loose connective tissue makes it mobile and, in children, the mucous membrane may have developed more strongly than the muscularis mucosae. They concluded that two factors might operate: first, a congenital weakness of tissue with an unduly wide urethra and, secondly, an acquired factor such as debility or inflammation. Other theories frequently mentioned are redundancy of the urethral ...

Through the identificat,ion of copper as an active agent in hemoglobin building in the rat by Hart, Steenbock, and associates (l-7), later confirmed by McHargue, Healy, and Hill (8), the role of this element in life processes has acquired new and increased importance. Because of this newly discovered function and also because of its general occurrence in food materials (9, 10)-a fact which sugg...

Eleven out of a series of twenty-nine patients (37-9%) with acute copper sulphate poisoning developed acute renal failure. Intravascular haemolysis appeared to be the chief factor responsible for renal lesions in these patients. Histological lesions observed in the kidney varied from those of mild shock to well established acute tubular necrosis. In one case, granulomatous lesions were seen in ...

Lead and zinc poisoning have been recorded in a variety of bird species, including migrating waterfowl such as Canada Geese (Branta canadensis), at sites contaminated with mine waste from lead and zinc mines in the Tri-State Mining District, Kansas, Oklahoma, and Missouri, USA. The adverse health impacts from mine waste on these birds may, however, be more extensive than is apparent from incide...
