OBJECTIVE We assessed the effect of 670-nm light therapy on growth and hatching kinetics in chickens (Gallus gallus) exposed to dioxin. BACKGROUND DATA Photobiomodulation has been shown to stimulate signaling pathways resulting in improved energy metabolism, antioxidant production, and cell survival. In ovo treatment with 670-nm light-emitting diode (LED) arrays improves hatching success and increases hatchling size in control chickens. Under conditions where developmental dioxin exposure is…

Survivorship and mortality implications of developmental 670-nm phototherapy: dioxin co-exposure.
TLDR
Overall survivorship and hatching success of chicks developmentally exposed to dioxin concentrations above the lethality threshold (>100 ppt TCDD) is improved by 670-nm LED treatment administered throughout the gestation period, but the relationship may be complicated by an LED-oil interaction.
Effects of 670-nm phototherapy on development.
TLDR
Results indicate that 670-nm phototherapy by itself does not adversely affect developing embryos and may improve the hatching survival rate, and a substantial decrease in overall and third-week mortality rates in the light-treated chickens.
670 nanometer light treatment attenuates dioxin toxicity in the developing chick embryo
TLDR
It is demonstrated that 670 nm phototherapy can mitigate the oxidative stress and energy deficit resulting from developmental exposure to TCDD while reducing T CDD‐induced embryo mortality and restores hepatic enzyme activities to control levels in TCDd‐exposed embryos.
Clinical and experimental applications of NIR-LED photobiomodulation.
TLDR
The experimental results demonstrate that NIR-LED light treatment stimulates mitochondrial oxidative metabolism in vitro, and accelerates cell and tissue repair in vivo, and represents a novel, noninvasive, therapeutic intervention for the treatment of numerous diseases linked to mitochondrial dysfunction.
Graphical Methods for Exploratory Analysis of Complex Data Sets
TLDR
Little-known modern graphical methods can be powerful tools for exploration of complex data and are provided using a pairs plot and several trellis plots in which the data appeared consistent or inconsistent with prior expectations and suggested unexpected findings that will motivate new research.
Effects of Toxic Stimuli Combinations on Determination of Exposure Limits
TLDR
This chapter discusses single stressor studies, multiple stressor Studies, and types of Combination Effects that have been studied over a period of years.

TLDR
These findings provide a link between the actions of monochromatic red to near-IR light on mitochondrial oxidative metabolism in vitro and retinoprotection in vivo and suggest that photobiomodulation may enhance recovery from retinal injury and other ocular diseases in which mitochondrial dysfunction is postulated to play a role.
The relative sensitivity of chicken embryos to yolk‐ or air‐cell‐injected 2,3,7,8‐tetrachlorodibenzo‐p‐dioxin
TLDR
Embryos exposed to high concentrations of TCDD injected into either the yolk or the air cell tended to die within the first 2 weeks of incubation, and only air-cell-injected embryos were able to hatch successfully.
Photobiomodulation Directly Benefits Primary Neurons Functionally Inactivated by Toxins
TLDR
The results are consistent with the hypothesis that the mechanism of photobiomodulation involves the up-regulation of cytochrome c oxidase, leading to increased energy metabolism in neurons functionally inactivated by toxins.
Effect of NASA light-emitting diode irradiation on wound healing.
TLDR
The use of NASA LED for light therapy alone, and in conjunction with hyperbaric oxygen, will greatly enhance the natural wound healing process, and more quickly return the patient to a preinjury/illness level of activity.
Effect of NASA light-emitting diode irradiation on molecular changes for wound healing in diabetic mice.
TLDR
It is believed that the use of NASA light-emitting diodes (LED) for light therapy will greatly enhance the natural wound healing process, and more quickly return the patient to a preinjury/illness level of activity.
The effects of dioxin on reproduction and development.
TLDR
In this report, low-dose developmental effects of dioxins on offspring in animal experiments and human studies were reviewed and risk assessment, methods to describe dosimetry, models to describe dose-response and approaches to express health risk are discussed.
COMPARATIVE DEVELOPMENTAL TOXICITY OF PLANAR POLYCHLORINATED BIPHENYL CONGENERS IN CHICKENS, AMERICAN KESTRELS, AND COMMON TERNS
TLDR
Concentrations of PCB 126 causing low-level toxic effects in common tern eggs are comparable to highest levels inCommon terns and Forster's terns in the field, suggesting additional involvement of other compounds in the Great Lakes.
THE EFFECT OF LASER IRRADIATION ON THE RELEASE OF bFGF FROM 3T3 FIBROBLASTS
TLDR
Results provide direct evidence that the proliferation of fibroblasts as a result of stimulation by low level laser irradiation may be associated with the autocrine production of bFGF from fibroblast cells in cell culture.
