1-Hexanoic acid stabilised copper nanoparticles were obtained. Cu 64 O phase could be found on the particle surface. During sintering, stabilising molecule, 1-hexanoic acid, reduced to and it introduced neckings between particles.

Copper deficiency is an uncommon, but treatable cause of hematologic abnormalities. We present and describe two interesting cases in this report. The first case was a 37-year-old man with history of short bowel syndrome and long-term total parenteral nutrition (TPN) presenting with pancytopenia and chronic symmetrical polyarthritis that resembled rheumatoid arthritis. The second case was a 64-y...

Data are presented of a 5-day balance study for iron, zinc, and copper in seven patients with short bowel syndrome on oral nutrition. The small bowel remnant of these patients varied from 40 to 110 cm (mean 64 cm) and was radiologically normal in all patients. The study was carried out an average 2.7 yr (range 1 to 5 yr) after intestinal resection. Balance materials (diets, urine, and stools) w...

A 64-year-old British Caucasian man presented with red skin wheals and breathlessness and then developed a progressive neurological syndrome. Investigation revealed hereditary haemachromatosis, porphyria, and a myelodysplastic syndrome. No unifying diagnosis was made, and his neurological symptoms remained unexplained, until further studies revealed an underlying copper deficiency.

A gene encoding the yeast ubiquitin was chemically synthesized and expressed in yeast under regulatory control of the copper metallothionein (CUP1) promoter. The gene was assembled in a one-step ligation reaction from eight oligonucleotide fragments ranging in length from 50 to 64 nucleotides. To facilitate mutagenesis and gene fusion studies, eight unique 6-base-cutting restriction enzyme site...
