The trend for melatonin–metal complexes was K+>Li+>Na+>Al3+>Ca2+. The binding and stable complex formation between both ligands, serotonin and melatonin with lithium, potassium and sodium is of biological importance. The binding of serotonin to lithium could provide an explanation for the therapeutic effects of lithium in depression treatment, whereas the binding of aluminium by melatonin could provide insight into the role of this element in the aetiology of Alzheimer's disease.]]> Fri 23 Sep 2022 14:43:22 SAST ]]> Effect of oligomerization on the photochemical properties of silicon octaphenoxyphthalocyanine https://commons.ufh.ac.za/vital/access/manager/Repository/vital:56885 Fri 23 Sep 2022 14:40:38 SAST ]]> Construction and characterization of carbon paste ultra-microelectrodes https://commons.ufh.ac.za/vital/access/manager/Repository/vital:56884 Fri 23 Sep 2022 14:37:23 SAST ]]> Comparative photosensitised transformation of polychlorophenols with different sulphonated metallophthalocyanine complexes in aqueous medium https://commons.ufh.ac.za/vital/access/manager/Repository/vital:56883 Fri 23 Sep 2022 14:35:53 SAST ]]>
