Age differences in everyday stressor-related negative affect: A coordinated analysis.

Psychol Aging 2018 Dec 13. Epub 2018 Dec 13.

Department of Biobehavioral Health and Medicine.

Advancing age is often characterized by preserved or even enhanced emotion regulation, which is thought to manifest in terms of age-related reductions in the within-person association between stressors and negative affect. Existing research from ecological momentary assessment and end-of-day daily diary studies examining such age-related benefits have yielded mixed results, potentially due to differences in samples, design, and measurement of everyday stressors and negative affect. We conducted a coordinated analysis of 5 ecological momentary assessments and 2 end-of-day daily diary studies to examine adult age differences in the within-person association between everyday stressors and negative affect.

DNA Methylation Analysis.

Methods Mol Biol 2019 ;1894:181-227

Institute of Occupational Diseases, Zhejiang Academy of Medical Sciences, Hangzhou, P. R. China.

DNA methylation is a process by which methyl groups are added to cytosine or adenine. DNA methylation can change the activity of the DNA molecule without changing the sequence. Methylation of 5-methylcytosine (5mC) is widespread in both eukaryotes and prokaryotes, and it is a very important epigenetic modification event, which can regulate gene activity and influence a number of key processes such as genomic imprinting, cell differentiation, transcriptional regulation, and chromatin remodeling.

Analysis of Nanomaterial Toxicity by Western Blot.

Methods Mol Biol 2019 ;1894:161-169

Department of Gastroenterology, Affiliated Children's Hospital, Zhejiang University School of Medicine, Hangzhou, Zhejiang Province, China.

Western blot is a routine biochemical technique for the immunodetection of proteins in cells and tissues exposed to nanomaterials (NMs). It is a sensitive method for protein analysis that involves the solubilization and separation of proteins by sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE), transferring and immobilizing proteins onto a solid support, and targeted immunoprobing of a specific antigen. As a convenient and reliable research tool, the western blot plays an irreplaceable role in the era of proteomics together with mass spectrometry and protein chip. Read More

Determination of Phosphorylated Histone H2AX in Nanoparticle-Induced Genotoxic Studies.

Methods Mol Biol 2019 ;1894:145-159

Department of Environmental and Occupational Health Sciences, School of Public Health and Information Sciences, University of Louisville, Louisville, KY, USA.

DNA double-strand breaks (DSBs), one of the most severe lesions of DNA damage triggered by various genotoxic insults, can lead to chromosome change, genomic instability, and even tumorigenesis if not repaired efficiently. In response to DNA damage, histone H2AX molecules are rapidly phosphorylated at serine 139 near the site of DNA DSBs and form γ-H2AX foci. As an early important cellular event linked to DNA damage and repair, γ-H2AX is a highly sensitive biomarker for "monitoring" DNA damage and consequently is a useful tool in genetic toxicology screen.
