Autoimmune thyroid diseases (AITD) are a group of both B cell- and T cell-mediated organ-specific autoimmune diseases. Graves' disease and Hashimoto thyroiditis are the two main clinical presentations of AITD. Both genetic and environmental factors have important roles in the development of AITD. Epigenetics have been considered to exert key roles in integrating those genetic and environmental ...

BACKGROUND It is now widely believed that health promotion strategies should go beyond education or communication to achieve significant behavioral changes among the target population. Environmental modifications are thought to be an important addition to a worksite health promotion program (WHPP). This review aimed to systematically assess the effectiveness of WHPPs with environmental modifica...

Biofilms are surface-attached communities of bacterial cells embedded in a self-produced matrix that are found ubiquitously in nature. The biofilm matrix is composed of various extracellular polymeric substances, which confer advantages to the encapsulated bacteria by protecting them from eradication. The matrix composition varies between species and is dependent on the environmental niche that...

Unlike the genome, the epigenome can be modified and hence some epigenetic risk markers have the potential to be reversed. Such modifications take place by means of drugs, diet or environmental exposures. It is widely accepted that epigenetic modifications take place during early embryonic and primordial cell development, but it is also important that we gain an understanding of the potential f...

Plants interact with their environment by modifying gene expression patterns. One mechanism for this interaction involves epigenetic modifications that affect a number of aspects of plant growth and development. Thus, the epigenome is highly dynamic in response to environmental cues and developmental changes. Flowering is controlled by a set of genes that are affected by environmental condition...

It has been encountering with large modifications and developments during recent decades and it makes large developments at Rey & Islamshahr regions. As the habitation areas as shaped in different dimensions. Thought it can investigate the implicational structural at large scales even at littler scales too. Nevertheless the essential applications of living areas on over coming life need such ha...

the epigenetic alterations like histone modifications , dna methylation and others remarkable categories  including nucleosome remodeling and rna mediated targeting have been strongly investigated  recently .in this way , beside the notable importance of dna methylation ,the histone modifications are the most important issues in the  tumorogenesis and cancer progression. moreover, the fluctuati...

There are numerous examples in psychology and other disciplines of the enduring effects of early experience on neural function. In this article, we review the emerging evidence for epigenetics as a candidate mechanism for these effects. Epigenetics refers to functionally relevant modifications to the genome that do not involve a change in nucleotide sequence. Such modifications include chemical...

Asthma is a complex, heterogeneous and chronic airway inflammatory disease with different clinical phenotypes caused by diverse triggers and pathophysiological mechanisms. Asthma heritability has been established in many genetic studies but it is evident that only genetic elements are not responsible for the development of asthma. Increasing rate of asthma incidence during past decades has impl...
