   Abstract : 5-aminolevulinic acid (5-ALA) and derivatives thereof are widely usedprodrugs in treatment of pre-malignant skin diseases of the cancer treatmentmethod photodynamic therapy (PDT). The target molecule in 5-ALAPDTis protoporphyrin IX (PpIX), which is synthesized endogenously from5-ALA via the heme pathway in the cell. READ MORE

5. 3. Fluorescence Spectroscopy for Quantitative Demarcation of Glioblastoma Using 5-Aminolevulinic Acid

   Author : Neda Haj-Hosseini; Karin Wårdell; Göran Salerud; Peter E Andersen; Linköpings universitet; []
   Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER;

   Abstract : Total resection of glioblastoma, the highly malignant brain tumor, is difficult to accomplish due to its diffuse growth and similarity to the surrounding brain tissue. A total resection is proven to increase patient survival. READ MORE

6. 4. ALA and m-ALA in bicontinuous lipid formulations: -Characterization and Transdermal Delivery

   Author : Johanna Bender; Chalmers University of Technology; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; passive diffusion; SAXS; monoolein; methyl 5-aminolevulinate hydrochloride; NMRD; sponge phase; 5-aminolevulinic acid hydrochloride; iontophoresis;

   Abstract : δ-Aminolevulinic acid (ALA) and its methyl ester (m-ALA) are both used in photodynamic therapy (PDT) of certain non melanoma skin cancers as the basal cell carcinoma (BCC). In PDT the cancer cells are destroyed by a photochemical reaction that occurs when a photosensitive molecule is irradiated with light of a certain wavelength. READ MORE

7. 5. New approaches for treatment of acute intermittent porphyria by enzyme substitution and gene therapy : evaluation in vitro and in vivo

   Author : Annika Johansson; Karolinska Institutet; Karolinska Institutet; []
   Keywords : Acute intermittent porphyria; adenovirus; 5-aminolevulinic acid; enzyme substitution; gene therapy; non-viral gene delivery; porphobilinogen; porphobilinogen deaminase; protoporphyrin;

   Abstract : Acute intermittent porphyria (AIP) is a rare inborn metabolic error of heme synthesis in which the activity of the third enzyme, porphobilinogen deaminase (PBGD), is deficient. It is clinically characterized by acute, potentially life-threatening neurologic attacks that are precipitated by various drugs, reproductive hormones and other factors. READ MORE
