Epigenetics and environmental exposures.
It is becoming increasingly apparent that genetic factors are inadequate to fully explain many processes that shape development and disease. For example, monozygotic twin pairs, despite sharing identical DNA sequences, are often discordant for many traits and diseases, indicating that the same genotype can give rise to distinct phenotypes. This points towards the involvement of additional facto...
متن کاملEnvironmental Exposures and Hepatocellular Carcinoma
Infection with hepatitis B and/or hepatitis C virus is a well-established risk factor for the development of hepatocellular carcinoma (HCC).

The label "sick building syndrome" is often used to imply the absence of a physiologic basis for symptoms in the built environment. Although building-related illness is widely recognized but considered rare, several well-studied mechanisms may be responsible for many symptoms in buildings. These mechanisms do not explain why some individuals perceive disability. Until researchers distinguish ph...
متن کاملEnvironmental Exposures and Parkinson’s Disease
Parkinson's disease (PD) affects millions around the world. The Braak hypothesis proposes that in PD a pathologic agent may penetrate the nervous system via the olfactory bulb, gut, or both and spreads throughout the nervous system. The agent is unknown, but several environmental exposures have been associated with PD. Here, we summarize and examine the evidence for such environmental exposures...
متن کاملParallel Outcomes: Comparing Effects of Environmental Contaminant Exposures with ADHD in Children
Attention deficit/hyperactivity disorder (ADHD), the most frequently diagnosed neurobehavioral disorder in children, affects more than 5% of the population worldwide. Although the etiology of ADHD is poorly understood, characteristics similar to those seen in children with ADHD also have been observed in children and animals exposed to lead or polychlori nated biphenyls (PCBs). Two literature r...
