Photoprotective Effect of the Plant Collaea argentina against Adverse Effects Induced by Photodynamic Therapy

open access: yesInternational Journal of Photoenergy, 2014
Photodynamic therapy (PDT) is a treatment modality for tumours and other accessible lesions based on the combination of light and a photosensitizer (PS) accumulated in the target tissue. The main disadvantage of PDT is PS retention after treatment during

Fluorescent redox-dependent labeling of lipid droplets in cultured cells by reduced phenazine methosulfate [PDF]

open access: yesHeliyon, 2020
Natural and synthetic phenazines are widely used in biomedical sciences. In dehydrogenase histochemistry, phenazine methosulfate (PMS) is applied as a redox reagent for coupling reduced coenzymes to the reduction of tetrazolium salts into colored ...

Delta-aminolevulinic acid cytotoxic effects on human hepatocarcinoma cell lines. [PDF]

open access: yesBMC Cancer, 2002
BACKGROUND: Acute Intermittent Porphyria is a genetic disorder of heme metabolism, characterized by increased levels of porphyrin precursors, delta-aminolevulinic acid (ALA) and porphobilinogen (PBG).

Influence of ceramide 2 on in vitro skin permeation and retention of 5-ALA and its ester derivatives, for Photodynamic Therapy [PDF]

open access: yesBrazilian Journal of Pharmaceutical Sciences, 2009
Photodynamic therapy (PDT) based on topical 5-aminolevulinic acid (5-ALA), an endogenous precursor of protoporphyrin, is an interesting approach for the treatment of skin cancer.

Acute intermittent porphyria in Argentina: an update. [PDF]

open access: yesBiomed Res Int, 2015
Porphyrias are a group of metabolic diseases that arise from deficiencies in the heme biosynthetic pathway. A partial deficiency in hydroxymethylbilane synthase (HMBS) produces a hepatic disorder named Acute Intermittent Porphyria (AIP); the acute porphyria is more frequent in Argentina.

Experimental protoporphyria: effect of bile acids on liver damage induced by griseofulvin. [PDF]

open access: yesBiomed Res Int, 2015
The effect of bile acids administration to an experimental mice model of Protoporphyria produced by griseofulvin (Gris) was investigated. The aim was to assess whether porphyrin excretion could be accelerated by bile acids treatment in an attempt to diminish liver damage induced by Gris.

Modulation of 5-Aminolevulinic acid mediated photodynamic therapy induced cell death in a human lung adenocarcinoma cell line [PDF]

open access: yes, 2016
Photodynamic therapy (PDT) is a cancer treatment involving the administration of a photosensitising drug which selectively accumulates in tumor tissue, followed by irradiation with appropriate wavelength light.

Photodynamic inactivation of planktonic and biofilm growing bacteria mediated by a meso-substituted porphyrin bearing four basic amino groups [PDF]

open access: yes, 2016
Biofilm-associated diseases account for 80% of all infections in humans. Due to the emergence of antibiotic resistances, alternative therapies such as Photodynamic Inactivation (PDI) of microorganisms have emerged.
