Photodynamic therapy of cancer: An update
Photodynamic therapy is a clinically approved, minimally invasive therapeutic procedure that can exert a selective cytotoxic activity toward malignant cells and can prolong survival in patients with inoperable cancers and significantly improve quality of life.

All the available evidence suggests that multi-antibiotic resistant strains are as easily killed by PDT as naive strains, and that bacteria will not readily develop resistance to PDT.
The Nuts and Bolts of Low-level Laser (Light) Therapy
The mechanisms of action of LLLT at a cellular and at a tissular level are covered and the various light sources and principles of dosimetry that are employed in clinical practice are summarized.
Biphasic Dose Response in Low Level Light Therapy
The molecular and cellular mechanisms in LLLT are covered, and some of the recent results in vitro and in vivo that provide scientific explanations for this biphasic dose response are described.
Photodynamic therapy and anti-tumour immunity
Photodynamic therapy (PDT) uses non-toxic photosensitizers and harmless visible light in combination with oxygen to produce cytotoxic reactive oxygen species that kill malignant cells by apoptosis
Proposed Mechanisms of Photobiomodulation or Low-Level Light Therapy
After the initial photon absorption events, numerous signaling pathways are activated via reactive oxygen species, cyclic AMP, NO, and Ca2+, leading to activation of transcription factors, which can lead to increased expression of genes related to protein synthesis, cell migration and proliferation,Anti-inflammatory signaling, anti-apoptotic proteins, and antioxidant enzymes.
Mechanisms of low level light therapy
This introductory review will cover some of the proposed cellular chromophores responsible for the effect of visible light on mammalian cells, including cytochrome c oxidase (with absorption peaks in the near infrared) and photoactive porphyrins.
Cell Death Pathways in Photodynamic Therapy of Cancer
Photodynamic therapy (PDT) is an emerging cancer therapy that uses the combination of non-toxic dyes or photosensitizers (PS) and harmless visible light to produce reactive oxygen species and destroy
