Association of adverse birth outcomes with prenatal exposure to vanadium: a population-based cohort study
Summary
Background Vanadium, an important pollutant produced from anthropogenic activities, has been suggested to be embryotoxic and fetotoxic in animal studies. However, little is known about its effects on humans. We aimed to assess the association of prenatal exposure to vanadium with the risk of adverse birth outcomes in babies born to women in China.
Methods For this populat...

Association between cadmium exposure and urolithiasis risk
A systematic review and meta-analysis
Abstract
Background: We performed a meta-analysis to determine whether a consistent relationship exists between cadmium exposure and urolithiasis in humans. Accordingly, we summarized and reviewed previously published quantitative studies.
Methods: Eligible studies with reference lists published before June 1, 2017 were obtained from searching several databases. Random effects models were ...

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 toxic heavy metals, such as arsenic, cadmium, chr...

Skeletal Muscle-Specific Overexpression of PGC-1α Induces Fiber-Type Conversion through Enhanced Mitochondrial Respiration and Fatty Acid Oxidation in Mice and Pigs
Abstract
Individual skeletal muscles in the animal body are heterogeneous, as each is comprised of different fiber types. Type I muscle fibers are rich with mitochondria, and have high oxidative metabolisms while type IIB fibers have few mitochondria and high glycolytic metabolic capacity. Peroxisome proliferator-activated ...

Sesamol Induces Human Hepatocellular Carcinoma Cells Apoptosis by Impairing
Mitochondrial Function and Suppressing Autophagy
Sesamol, a nutritional phenolic antioxidant compound enriched in sesame seeds, has been shown to have potential anticancer activities. This study aims at characterizing the antitumor efficacy of sesamol and unveiling the importance of mitochondria in sesamol-induced effects using a human hepatocellular carcinoma cell line, HepG2 cells. Results of this study ...

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 quercetin on the potential mechanism mediating these ...

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 mechanism whereby pomegranate extract lowers ...
