High signal intensity on magnetic resonance imaging is a better predictor of neurobehavioral performances than blood manganese in asymptomatic welders.
OBJECTIVES The aim of the study was to evaluate subclinical neurological effects in welders, using an extensive list of neurobehavioral batteries and determine if there is a link between pallidal… Expand
Idiopathic parkinsonism with superimposed manganese exposure: utility of positron emission tomography.
It is difficult to distinguish manganism from idiopathic parkinsonism by clinical signs only. Case history and examination: A 48-year-old welder for over 10 years complained of masked face, right… Expand
Increase in signal intensities on T1-weighted magnetic resonance images in asymptomatic manganese-exposed workers.
OBJECTIVES To clarify the clinical significance of increased signal intensities on T1 weighted magnetic resonance imaging (MRI) we performed a large-scale epidemiological study on asymptomatic… Expand

We have employed an estrogen receptor dependent transcriptional expression assay and E-Screen assay systems to evaluate the estrogenicity of various heavy metals and their species. Using the former,… Expand
Prenatal lead and cadmium co-exposure and infant neurodevelopment at 6 months of age: the Mothers and Children's Environmental Health (MOCEH) study.
BACKGROUND This study aimed to explore the developmental effects of prenatal exposure to Pb and Cd on infant cognitive development at 6 months of age. METHODS Between 2006 and 2010, the blood… Expand
Mercury levels in maternal and cord blood and attained weight through the 24 months of life.
Birth weight is a strong determinant of attained weight at early ages. Until now, many studies have reported that low birth weight corresponds with high mercury levels. However, the relationship… Expand
Occupations and Parkinson's disease: a multi-center case-control study in South Korea.
OBJECTIVE We performed a hospital based case-control study in South Korea (1) to clarify the role of occupational exposure, and especially manganese (Mn) exposure in the etiology of Parkinson's… Expand
A Case of Acute Organotin Poisoning
Alkyl compounds of tin chlorides are widely used for the production of plastics in the chemical industry. They inhibit the dissociation of hydrochloric acid from polyvinyl chloride (PVC) and in… Expand
Maternal Blood Manganese and Early Neurodevelopment: The Mothers and Children’s Environmental Health (MOCEH) Study
Background Manganese is an essential trace element and common component of water, soil, and air. Prenatal manganese exposure may affect fetal and infantile neurodevelopment, but reports on in utero… Expand
