Cobalt toxicity in humans. A review of the potential sources and systemic
health effects
Abstract
Cobalt (Co) and its compounds are widely distributed in nature and are part of numerous
anthropogenic activities. Although cobalt has a biologically necessary role as metal constituent
of vitamin B12, excessive exposure has been shown to induce various adverse health effects.
This review provides an extended overview of the possible Co sources and related intake routes,
the detection and quantification methods for Co intake and the interpretation thereof, and the
reported health ...

Cadmium Handling, Toxicity and Molecular Targets Involved during Pregnancy: Lessons from Experimental Models
Abstract: Even decades after the discovery of Cadmium (Cd) toxicity, research on this heavy metal
is still a hot topic in scientific literature: as we wrote this review, more than 1440 scientific articles
had been published and listed by the PubMed.gov website during 2017. Cadmium is one of the most
common and harmful heavy metals present in our environment. Since pregnancy is a very particular physiological condition that could impact and modify essential pathways involved in ...

Associations between toxic and essential trace elements in maternal blood and fetal congenital heart defects
A B S T R A C T
Prenatal exposure to toxic trace elements, including heavy metals, is an important public health concern. Few studies have assessed if individual and multiple trace elements simultaneously affect cardiac development. The current study evaluated the association between maternal blood lead (Pb), cadmium (Cd), chromium (Cr), copper (Cu), mercury (Hg), and selenium (Se) levels and congenital heart defects (CHDs) in offspring. This hospital-based case-control study ...

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 population-based cohort study, the Healthy Baby Cohort, women were recruited from three cities in Hubei ...

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 used to summary the overall estimate of the multivariate adjusted odds ratios (ORs) with 95% con...

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, chromium, and lead2. However, there have been few quantitative analyses of the effects of toxic heavy ...

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 receptor gamma coactivator 1α (PGC-1α), a transcriptional co-activator that regulates mitochon...
