Background: DNA is subject to constant chemical modification and damage, which eventually results in variable mutation rates throughout the genome. Although detailed molecular mechanisms of DNA damage and repair are well understood, damage impact and execution of repair across a genome remain poorly defined.

Results: To bridge the gap between our understanding of DNA repair and mutation distributions, we developed a novel method, AP-seq, capable of mapping apurinic sites and 8-oxo-7,8-dihydroguanine bases at approximately 250-bp resolution on a genome-wide scale. Read More

Space-time heterogeneity of hand, foot and mouth disease in children and its potential driving factors in Henan, China.

BMC Infect Dis 2018 Dec 7;18(1):638. Epub 2018 Dec 7.

China National Center for Food Safety Risk Assessment, Beijing, 100022, China.

Background: Hand, foot and mouth disease (HFMD) has become a substantial threat recently. However few studies have quantified spatiotemporal heterogeneity of HFMD and detected spatiotemporal interactive effect of potential driving factors on this disease.

Methods: Using GeoDetector and Bayesian space-time hierarchy model, we characterized the epidemiology of HFMD in Henan, one of the largest population provinces in China, from 2012 to 2013, and quantified the impacts of potential driving factors. Read More

Contrasting effects of acute and chronic stress on the transcriptome, epigenome, and immune response of Atlantic salmon.

Epigenetics 2018 Dec 11. Epub 2018 Dec 11.

a Centre for Sustainable Aquatic Research, College of Science, Swansea University , Swansea , SA2 8PP , UK.

Stress experienced during early life may have lasting effects on the immune system, with impacts on health and disease dependent on the nature and duration of the stressor. The epigenome is especially sensitive to environmental stimuli during early life and represents a potential mechanism through which stress may cause long-lasting health effects. However, the extent to which the epigenome responds differently to chronic vs acute stressors is unclear, especially for non-mammalian species. Read More

Exploring Dynamics and Structure of Biomolecules, Cryoprotectants, and Water Using Molecular Dynamics Simulations: Implications for Biostabilization and Biopreservation.

Annu Rev Biomed Eng 2018 Dec 10. Epub 2018 Dec 10.

Center for Engineering in Medicine and BioMEMS Resource Center, Massachusetts General Hospital, Harvard Medical School, Charlestown, Massachusetts 02129, USA; email: , ,

Successful stabilization and preservation of biological materials often utilize low temperatures and dehydration to arrest molecular motion. Cryoprotectants are routinely employed to help the biological entities survive the physicochemical and mechanical stresses induced by cold or dryness. Molecular interactions between biomolecules, cryoprotectants, and water fundamentally determine the outcomes of preservation. Read More
