INTRODUCTION Effective strategies for managing acute behavioural disturbances (ABDs) within emergency departments (EDs) are needed given their rising occurrence and negative impact on safety, psychological wellbeing, and staff turnover. Non-pharmacological interventions for ABD management generally fall into four categories: environmental modifications; policies; practice changes; and education...

Experimental evidence of environmental features important for physical activity is challenging to procure in real world settings. The current study aimed to investigate the causal effects of environmental modifications on a photographed street's appeal for older adults' walking for transport. Secondly, we examined whether these effects differed according to gender, functional limitations, and c...

Epigenetic mechanisms, such as histone modifications and DNA methylation, have been shown to play a key role in the regulation of gene transcription. Results of recent studies indicate that a novel "bivalent" chromatin structure marks key developmental genes in embryonic stem cells (ESCs), wherein a number of untranscribed lineage-control genes, such as Sox1, Nkx2-2, Msx1, Irx3, and Pax3, are e...

'Epigenetics' has been defined as the study of 'mitotically and/or meiotically heritable changes in gene function that cannot be explained by changes in DNA sequence'. Chromatin modifications are major carriers of epigenetic information that both reflect and affect the transcriptional states of underlying genes. Several histone modifications are key players that are responsible for classical ep...

Although landscapes of several histone marks are now available for Arabidopsis thaliana and Oryza sativa, such profiles remain static and do not provide information about dynamic changes of plant epigenomes in response to developmental or environmental cues. Here, we analyzed the effects of light on four histone modifications (acetylation and trimethylation of lysines 9 and 27 on histone H3: H3...

OBJECTIVES Lupus flares are triggered by environmental agents that cause oxidative stress, but the mechanisms involved are unclear. The flares are characterized by oxidative modifications of proteins by 4-hydroxynonenals, malondialdehydes, carbonyls and nitration. These modifications have been proposed to induce and perpetuate lupus flares by "altered self" mechanisms. An epigenetically altered...

Epigenetic modifications are increasingly recognized to play a role in the etiology and pathophysiology of schizophrenia other psychiatric disorders with developmental origins. Here, we summarize clinical preclinical findings epigenetic alterations relevant disease models discuss their putative origin. Recent suggest that certain risk loci can influence stochastic variation gene expression thro...
