Compared with the traditional treatment, photodynamic therapy (PDT) in the treatment of
malignant tumors has the advantages of less damage to normal tissues, quick therapeutic …

Abstract Exogenous 5‐aminolevulinic acid (ALA) is taken up directly by bacteria, yeasts,
fungi, and some parasites, which then induces the accumulation of protoporphyrin IX (PPIX) …

Synthesis of water soluble porphyrin and phthalocyanine derivatives with, respectively, eight
and sixteen galactose units has been carried out. The combined preliminary photophysical …

The mechanisms of cell death can be predetermined (programmed) or not and categorized
into apoptotic, autophagic and necrotic pathways. The process of Hayflick limits completes …

The aim of this study is to investigate the antitumor effects and possible mechanisms of meta-
tetrahydroxyphenylchlorin-mediated photodynamic therapy (m-THPC-PDT) on human …

BACKGROUND: Photodynamic therapy (PDT) is a therapeutic modality capable of inducing
cell death by oxidative stress through activation of a sensitizer by light. Aryl-porphyrin with …

Optical absorption and emission properties of Ho 3+ ions in barium–gallium-germanate
glass are investigated. A significant result is that the emission intensity of Ho 3+: 5 I 7→ 5 I 8 …

In Er^ 3+/Yb^ 3+ codoped Na_2O-ZnO-PbO-GeO_2-TeO_2 (NZPGT) glass fiber, a clear and
compact green upconversion amplified spontaneous emission (ASE) trace is observed, and …

The development of new stable 4, 5, 6, 7-tetrahydropyrazolo [1, 5-a] pyridine-fused chlorins
with high absorption properties at 650 nm, and their impressive photosensitizer ability …

Diarylporphyrins (1‐5) with hydroxyl groups and halogens as substituents were prepared by
condensation between unsubstituted dipyrromethane and halogenated m …
