Protein bodies in catecholamine neurons of the normal human brain contain arginine-rich proteins similar to those present in the core of Lewy bodies in Parkinsonian brains. Lewy bodies are known also to contain phospholipids in their core, demonstrable with Baker's

Current chemical concepts were applied to Weigert's, M. Heidenhain's and Verhoeff's iron hemateins, Mayer's acid hemalum stain and the corresponding brazilein compounds. Fe bonds tightly to oxygen in preference to nitrogen and is unlikely to react with lysyl and arginyl

Analytically pure hematoxylin (Htx), pentaacetylhematoxylin (PAHtx), and hematein (Hm) were isolated and characterized by 1H-NMR spectroscopy. The VIS/UV spectra of Htx and Hm were recorded in MeOH and in H2O at various pH values. The molar extinction coefficients of the

An amperometric penicillin biosensor with enhanced sensitivity was successfully developed by co-immobilization of multi-walled carbon nanotubes (MWCNTs), hematein, and beta-lactamase on glassy carbon electrode using a layer-by-layer assembly technique. Under catalysis of the immobilized enzyme, penicillin was hydrolyzed, decreasing the

The electrospray ionisation mass spectra of the neoflavanoids brazilin and hematoxylin are reported in both their reduced (1 and 2, respectively) and their oxidised forms (3 and 4, respectively). In the reduced forms, breakdown pathways under collision induced decomposition (CID)
