Light Emitting Diode Therapy (LEDT) encompasses two primary therapeutic approaches: photodynamic Therapy (PDT) and photobiomodulation Therapy (PBMT). Photodynamic therapy (PDT) utilises light-sensitive compounds combined with LED light to generate reactive oxygen species, which selectively target and destroy abnormal cells.
The transcranial photobiomodulation or transcranial low level light therapy is limited in neuromodulation due to several reasons: An excessive dose of radiation can be harmful. [ 21 ] Therefore, at adequate doses of light there may be stimulation of growth, but at high doses excessive singlet oxygen may be produced and its chemical action may ...
Fluorescence biomodulation is a form of photobiomodulation, which utilizes fluorescence energy to induce multiple transduction pathways that can modulate biological processes through the activation of photoacceptors found within many different cell and tissue types. According to Magalhães and Yoshimura, photoacceptors are molecules that do not ...
Photostimulation is the use of light to artificially activate biological compounds, cells, tissues, or even whole organisms.Photostimulation can be used to noninvasively probe various relationships between different biological processes, using only light.
Photobiology is the scientific study of the beneficial and harmful interactions of light (technically, non-ionizing radiation) in living organisms. [1] The field includes the study of photophysics, photochemistry, photosynthesis, photomorphogenesis, visual processing, circadian rhythms, photomovement, bioluminescence, and ultraviolet radiation effects.
FBI Director Christopher Wray’s resignation announcement was the latest, and inevitable, step in the accumulation of massive and unusual power around President-elect Donald Trump.
Cells in vivo may be partially protected against the effects of photodynamic therapy by the presence of singlet oxygen scavengers (such as histidine). Certain skin cells are somewhat resistant to PDT in the absence of molecular oxygen; further supporting the proposal that the Type-II process is at the heart of photoinitiated cell death. [3]
