Copper in health test tubes that damaged DNA in the cells of a Menkes patient can be repaired. In time, the procedures needed to repair damaged genes in the human body may be found. Wilson's disease is a rare autosomal (chromosome 13) recessive genetic disorder of copper transport that causes an excess of copper to build up in the liver. This results in liver toxicity, among other symptoms. The disease is now treatable. Wilson's disease is produced by mutational defects of a protein that transports copper from the liver to the bile for excretion. The disease involves poor incorporation of copper into ceruloplasmin
Drug delivery to the brain these characteristics that makes a drug able to pass through the blood–brain barrier. The study found that barrier permittivity is "based on the measurement of the surface activity and as such takes into account the molecular properties of both hydrophobic and charged residues of the molecule of interest." They found that there is not a simple answer to what compounds transverse the blood–brain barrier and what does not. Rather, it is based on the complex analysis of the surface activity of the molecule as well as relative size. Other problems persist besides just simply getting through the blood–brain barrier. The
