Disturbed copper (Cu) homeostasis may be associated with the pathological processes in Alzheimer's disease (AD). In the present report, we evaluated the efficacy of oral Cu supplementation in the treatment of AD in a prospective, randomized, double-blind, placebo-controlled phase 2 clinical trial in patients with mild AD for 12 months. Sixty-eight subjects were randomized. The treatment was well-tolerated. There were however no significant differences in primary outcome measures (Alzheimer's Disease Assessment Scale, Cognitive subscale, Mini Mental Status Examination) between the verum [Cu-(II)-orotate-dihydrate; 8 mg Cu daily] and the placebo group. Despite a number of findings supporting the hypothesis of environmental Cu modulating AD, our results demonstrate that oral Cu intake has neither a detrimental nor a promoting effect on the progression of AD.

Structure-dependant models of intercalation with DNA and base-pair oligonucleotides are presented at the molecular level for some cytostatic agents. The application of these procedures is interesting to teacher and student in that they provide rational foundation for the development of new intercalating drugs.

Three German patients developed nosocomial pneumonia after cardiac surgery and had Burkholderia cepacia complex detected in respiratory specimens. Two patients died of septic multi-organ failure. Whole-genome sequencing detected genetically identical B. cepacia complex strains in patient samples, from a batch of octenidine mouthwash solution, which had been used for nursing care, as well as in samples obtained from the manufacturer during production. Contamination of medical products during manufacturing may lead to international outbreaks.
