Effect of LED photobiomodulation on fluorescent light induced changes in cellular ATPases and Cytochrome c oxidase activity in Wistar rat.

Background: Fluorescent light exposure at night alters cellular enzyme activities resulting in health defects. Studies have demonstrated that light emitting diode photobiomodulation enhances cellular enzyme activities.

Objective: The objectives of this study are to evaluate the effects of fluorescent light induced changes in cellular enzymes and to assess the protective role of pre exposure to 670 nm LED in rat model.

Second digit and fourth digit ratio--an adjunct tool to predict obstructive sleep apnea.

Obstructive sleep apnea (OSA) is a sleep related breathing disorder associated with high morbidity and mortality. Digit ratio (2D:4D) a sexually dimorphic trait is a putative indicator of prenatal testosterone exposure and adult testosterone level. Present study aimed at investigating the correlation between 2D:4D ratio and OSA based on the study conducted on 290 volunteered participants of both the sexes in the age range of 20-45 years.

Protective effect of light emitting diode phototherapy on fluorescent light induced retinal damage in Wistar strain albino rats.

Background: Artificial light at night alters retinal physiology. Several studies have shown that light emitting diode phototherapy protects the retina from the damaging effects of acute light exposure.

Objective: The aim of this study has been to elucidate the protective effects of 670 nm LED light on retinal damage induced by chronic fluorescent light in Wistar rats.

Effect of REM sleep deprivation on the antioxidant status in the brain of Wistar rats.

Background: Rapid eye movement [REM] sleep deprivation is a stressor. It results in a predictable syndrome of physiological changes in rats. It has been proposed that reactive oxygen species and the resulting oxidative stress may be responsible for some of the effects of sleep deprivation.

Effect of alpha-ketoglutarate on neurobehavioral, neurochemical and oxidative changes caused by sub-chronic cyanide poisoning in rats.

Recent studies revealed that alpha-ketoglutarate (A-KG) alone or with sodium thiosulfate (STS) provide significant protection against acute and sub-acute cyanide poisoning in rodents. This study addresses the protective effect of A-KG and/or STS in sub-chronic (90 days) cyanide poisoning. Wistar rats were divided into seven groups (n = 10): Control animals, potassium cyanide (KCN) A-KG, STS, KCN + A-KG, KCN + STS and KCN + A-KG + STS.
