Characteristics of Fluorescent Intraoperative Dyes Helpful in Gross Total Resection of High-Grade Gliomas—A Systematic Review

Diagnostics, 2020
Background: A very important aspect in the treatment of high-grade glioma is gross total resection to reduce the risk of tumor recurrence. One of the methods to facilitate this task is intraoperative fluorescence navigation.

Genetic factors affecting intraoperative 5-aminolevulinic acid-induced fluorescence of diffuse gliomas

Radiology and Oncology, 2017
In patients operated for malignant glioma, 5-aminolevulinic acid (5-ALA)-induced fluorescence guidance is useful. However, we occasionally experience instances of non-visible fluorescence despite a histopathological diagnosis of high-grade glioma.

5-Aminolevulinic acid-induced severe hypotension during transurethral resection of a bladder tumor: a case report

JA Clinical Reports, 2019
Background Although 5-aminolevulinic acid (5-ALA) is used for the photodynamic diagnosis of bladder tumors, hypotension is the most commonly observed adverse effect.

Biophysical aspects of photodynamic therapy [PDF]

, 2012
Photodynamic therapy (PDT) is a multimodality cancer treatment available for the palliation or eradication of systemic and cutaneous malignancies. In this thesis, the application of PDT is for the treatment of non-melanoma skin cancer (NMSC).

Pale-green phenotype of atl31atl6 double mutant leaves is caused by disruption of 5-aminolevulinic acid biosynthesis in Arabidopsis thaliana.

PLoS ONE, 2015
Arabidopsis ubiquitin ligases ATL31 and homologue ATL6 control the carbon/nitrogen nutrient and pathogen responses. A mutant with the loss-of-function of both atl31 and atl6 developed light intensity-dependent pale-green true leaves, whereas the single ...

5-Aminolevulinic acid-mediated sonosensitization of rat RG2 glioma cells in vitro

, 2016
Sonodynamic therapy (SDT) is a promising technique based on the ability of certain substances, called sonosensitizers, to sensitize cancer cells to non-thermal effects of low-energy ultrasound waves, allowing their destruction.

Effect of 5-aminolevulinic acid on yield and quality of lettuce in sunlit greenhouse [PDF]

, 2016
The role of 5-aminolevulinic acid (ALA) as a precursor of chlorophyll and heme is well documented. Low concentration of exogenous ALA has been found to regulate plant growth and increase crop yield, but there is little information on how ALA influences ...
