Several studies have proven the important influence that environmental exposures have in the individual's susceptibility to suffer allergy and other related diseases, mostly during embryonic or early life. Although the relationship between the environment and allergic diseases had been previously reported, one interesting attempt to describe this relationship was Strachan's hygiene hypothesis, ...

Environmental proteomics, the study of changes in the abundance of proteins and their post-translational modifications, has become a powerful tool for generating hypotheses regarding how the environment affects the biology of marine organisms. Proteomics discovers hitherto unknown cellular effects of environmental stressors such as changes in thermal, osmotic, and anaerobic conditions. Proteomi...

The risk of developing neurodegenerative disorders such as Alzheimer's disease or Parkinson's disease is influenced by genetic and environmental factors. Environmental events occurring during development or later in life can be related to disease susceptibility. One way by which the environment may exert its effect is through epigenetic modifications, which might affect the functioning of genes...

Over the last decade a shift in paradigm has occurred with respect to the interaction between environment and genes. It is now clear that animal genomes are regulated to a large extent as a result of input from environmental events and experiences, which cause short- and long-term modifications in epigenetic markings of DNA and histones. In this review, the evidence that such epigenetic modific...

BACKGROUND There is strong evidence to suggest that multiple work-related health problems are preceded by a higher need for recovery. Physical activity and relaxation are helpful in decreasing the need for recovery. This article aims to describe (1) the development and (2) the design of the evaluation of a daily physical activity and relaxation intervention to reduce the need for recovery in of...

BACKGROUND DNA methylation is sensitive and responsive to stressful environmental conditions. Nonetheless, the extent to which condition-induced somatic methylation modifications can impose transgenerational effects remains to be fully understood. Even less is known about the biological relevance of the induced epigenetic changes for potentially altered well-being of the organismal progenies re...

The ability of environmental factors to shape health and disease involves epigenetic mechanisms that mediate gene-environment interactions. Metastable epiallele genes are variably expressed in genetically identical individuals due to epigenetic modifications established during early development. DNA methylation within metastable epialleles is stochastic due to probabilistic reprogramming of epi...

background: tricyclic antidepressants (tcas) poisoning is the most common poisoning in the poisoning emergency department of noor hospital, isfahan, iran. the objective of this study was to compare qrs interval duration with ravr³3mm and r/savr³ 0.7 in predicting: serious complications of acute tca toxicity. methods and materials: this study was descriptive – analytic and prospective cohort. tc...

The aim of the present article is to provide a summary of the epigenetic modifications that might occur in children exposed to heavy metals pollutants. It is known that children are more susceptible to environmental pollutants, because their detoxification enzymes are less competent, and this may lead to alterations in chromatin structure or of DNA causing, in turn, epigenetic modifications. Li...

A growing area of epigenetics research focuses on changes in gene expression that occur without altering the primary sequence, exclusively based on DNA, RNA, or protein modifications. Epigenetic modifications have been shown to change based on nutrition and environmental factors, and have been implicated in human diseases such as cancer and aging. In some cases, epigenetic changes are heritable...
