effect of concentration and application methods of 5-aminolevulinic acid on inducing cold resistance of soybean (glycine max l.)
compound of 5-aminolevulinic acid (5-ala) has herbicide behavior in high concentration. while, it acts as growth regulator at low concentrations and causes resistance to various stresses incluing cold and salibity. therefore the exogenous application of 5-aminolevulinic acid was investigated to induce cold stress tolerance in young soybean plants (glycine max l.). the experiment was conducted a...
متن کامل5-Aminolevulinic acid synthesis in Escherichia coli.
A hemA mutant of Escherichia coli containing a multicopy plasmid which complemented the mutation excreted 5-aminolevulinic acid (ALA) into the medium. [1-14C]glutamate was substantially incorporated into ALA by this strain, whereas [2-14C]glycine was not. Periodate degradation of labeled ALA showed that C-5 of ALA was derived from C-1 of glutamate. The synthesis of ALA by two sonicate fractions...
متن کاملEffect of Silver Nanoparticles on Improving the Efficacy of 5-Aminolevulinic Acid-Induced Photodynamic Therapy
Introduction: The most important limitation of 5-aminolevulinic acid (5-ALA)-induced photodynamic therapy (PDT) is the efficacy of the cells in converting 5-ALA to protoporphyrin IX. The present study aimed to investigate the effectiveness of silver nanoparticles (AgNPs) with the photosensitivity at the surface plasmon resonance wavelength on 5-ALA-mediated PDT. Material and Methods: First of a...
متن کامل5-Aminolevulinic acid synthesis in epimastigotes of Trypanosoma cruzi.
BACKGROUND AND AIMS Trypanosoma cruzi is the causative agent of Chagas disease or American trypanosomiasis. The parasite manifests a nutritional requirement for heme compounds because of its biosynthesis deficiency. The aim of this study has been to investigate the presence of metabolites and enzymes of porphyrin pathway, as well as ALA formation in epimastigotes of T. cruzi, Tulahuén strain, T...
متن کاملPain associated with photodynamic therapy using 5-aminolevulinic acid or 5-aminolevulinic acid methylester on tape-stripped normal skin.
BACKGROUND Pain during and after topical photodynamic therapy (PDT) is one of the few severe adverse effects of the new treatment of skin diseases. OBJECTIVE To compare the pain experienced in normal skin treated with 5-aminolevulinic acid (ALA) PDT and 5-aminolevulinic methylester (ALA-ME) PDT. DESIGN Double-blind randomized trial. INTERVENTIONS Twenty healthy volunteers were treated ran...
