A Case-Control Study of Skin Cancer and Exposure of Toxic Heavy Metals Dear Editor: The prevalence of skin cancer is increasing in Korea1. Although increased public awareness has contributed to this trend, other risk factors or mechanisms in addition to ultraviolet-exposure may be involved. It is known that exposure to heavy metals contributes to the development of skin cancers2. The main threats to human health are associated with ...

Quercetin induces mitochondrial biogenesis in experimental traumatic brain injury via the PGC-1α signaling pathway Abstract: Quercetin, a dietary flavonoid used as a food supplement, has been found to have protective effect against mitochondria damage after traumatic brain injury (TBI) in mice. However, the mechanisms underlying these effects are still not well understood. The aim of the present study was to investigate the effect of ...

Pomegranate extract decreases oxidative stress and alleviates mitochondrial impairment by activating AMPK-Nrf2 in hypothalamic paraventricular nucleus of spontaneously hypertensive rats High blood pressure, or “hypertension,” is associated with high levels of oxidative stress in the paraventricular nucleus of the hypothalamus. While pomegranate extract is a known antioxidant that is thought to have antihypertensive effects, the ...

Neuroprotection by quercetin via mitochondrial function adaptation in traumatic brain injury: PGC-1a pathway as a potential mechanism Abstract The aim of this study was to investigate the neuroprotective effects of quercetin in mouse models of traumatic brain injury (TBI) and the potential role of the PGC-1a pathway in putative neuroprotection. Wild-type mice were randomly assigned to four groups: the sham group, the TBI group, the ...
