Predicting mean ribosome load for 5'UTR of any length using deep learning.

PLoS Comput Biol 2021 May 10;17(5):e1008982. Epub 2021 May 10.

Department of Informatics, Technical University of Munich, Garching, Germany.

The 5' untranslated region plays a key role in regulating mRNA translation and consequently protein abundance. Therefore, accurate modeling of 5'UTR regulatory sequences shall provide insights into translational control mechanisms and help interpret genetic variants. Recently, a model was trained on a massively parallel reporter assay to predict mean ribosome load (MRL)-a proxy for translation rate-directly from 5'UTR sequence with a high degree of accuracy.

Collectively coping with coronavirus: Local community identification predicts giving support and lockdown adherence during the COVID-19 pandemic.

Br J Soc Psychol 2021 May 10. Epub 2021 May 10.

Università Degli Studi della Campania Luigi Vanvitelli, Naples, Italy.

The role of shared identity in predicting both ingroup helping behaviour and adherence to protective norms during COVID-19 has been extensively theorized, but remains largely under-investigated. We build upon previous Social Identity research into community resilience by testing the role of pre-existing local community (or 'neighbourhood') identity as a predictor of these outcomes, via the mediator of perceived social support. Community residents in the UK completed a longitudinal online survey four months before lockdown (T1; N = 253), one month before lockdown (T2; N = 217), and two months into lockdown (T3; N = 149).

A Bayesian approach to comparing common models of life-course epidemiology.

Int J Epidemiol 2021 May 10. Epub 2021 May 10.

Jacobs Center for Productive Youth Development, University of Zurich, Zurich, Switzerland.

Background: Life-course epidemiology studies people's health over long periods, treating repeated measures of their experiences (usually risk factors) as predictors or causes of subsequent morbidity and mortality. Three hypotheses or models often guide the analyst in assessing these sequential risks: the accumulation model (all measurement occasions are equally important for predicting the outcome), the critical period model (only one occasion is important) and the sensitive periods model (a catch-all model for any other pattern of temporal dependence).

Methods: We propose a Bayesian omnibus test of these three composite models, as well as post hoc decompositions that identify their best respective sub-models. Read More
