Ego networks associated with e-cigarette use among college fraternity students: a cross-sectional study.

Objective: To use egocentric network analysis (ENA) to identify how the role of social networks relates to e-cigarette use among college fraternity members.

Participants: 212 fraternity members participated in this study.

Methods: Hierarchical logistic regression analyses assessed the relationship between egocentric network variables and ever use and current use of e-cigarettes.

An expert consensus statement on biomarkers of ageing for use in intervention studies.

Biomarkers of ageing serve as important outcome measures in longevity-promoting interventions. However, there is limited consensus on which specific biomarkers are most appropriate for human intervention studies. This work aimed to address this need by establishing an expert consensus on biomarkers of ageing for use in intervention studies via the Delphi method.

From Ridge 2 Reef: An interdisciplinary model for training the next generation of environmental problem solvers.

Regional and global environmental challenges have become increasingly complex and require broader solutions than a single discipline can provide. Although there is a growing need for interdisciplinary research, many graduate education programs still train students within the confines of a particular discipline or specialty. The Ridge 2 Reef research traineeship program at the University of California, Irvine, aimed to provide transferable and interdisciplinary skill training to prepare graduate students from different disciplines to address current and future environmental challenges.

Elevated levels of intracellular RNA lariats suppress the antiviral response.

Unlabelled: Recent studies report the genetic loss of the lariat debranching enzyme ( ) activity increases susceptibility to viral infection. Here, we show that more than 25% of human introns contain large hairpin structures created by the folding of two elements inserted in opposite orientation. In wildtype cells, this large reservoir of endogenous dsRNA is efficiently degraded.
