PP2A-Tws dephosphorylates Map205, is required for Polo localization to microtubules and promotes cytokinesis in Drosophila.

Cell Div

December 2024

Institute for Research in Immunology and Cancer, Département de biochimie et médecine moléculaire, Université de Montréal, Montreal, Québec, Canada.

Background: Mitosis and cytokinesis are regulated by reversible phosphorylation events controlled by kinases and phosphatases. Drosophila Polo kinase, like its human ortholog PLK1, plays several roles in this process. Multiple mechanisms contribute to regulate Polo/PLK1 activity, localization and interactions.

Background: Epistasis, the phenomenon where the effect of one gene (or variant) is masked or modified by one or more other genes, significantly contributes to the phenotypic variance of complex traits. Traditionally, epistasis has been modeled using the Cartesian epistatic model, a multiplicative approach based on standard statistical regression. However, a recent study investigating epistasis in obesity-related traits has identified potential limitations of the Cartesian epistatic model, revealing that it likely only detects a fraction of the genetic interactions occurring in natural systems.

Bias in machine learning applications to address non-communicable diseases at a population-level: a scoping review.

BMC Public Health

December 2024

Upstream Lab, MAP Centre for Urban Health Solutions, Li Ka Shing Knowledge Institute, Unity Health Toronto, 30 Bond Street, Toronto, ON, M5B 1W8, Canada.

Background: Machine learning (ML) is increasingly used in population and public health to support epidemiological studies, surveillance, and evaluation. Our objective was to conduct a scoping review to identify studies that use ML in population health, with a focus on its use in non-communicable diseases (NCDs). We also examine potential algorithmic biases in model design, training, and implementation, as well as efforts to mitigate these biases.

A systematic review of the comparative effects of sound and music interventions for intensive care unit patients' outcomes.

Aust Crit Care

December 2024

Department of Music, Canadian Centre for Ethnomusicology (CCE), Department of Performing Arts, Faculty of Communication and Media Studies, University for Development Studies, Ghana; Department of Music, Faculty of Arts, University of Alberta, 3-98 Fine Arts Building, Edmonton, AB, T6G 2C9, Canada. Electronic address:

Background: Despite syntheses of evidence showing efficacy of music intervention for improving psychological and physiological outcomes in critically ill patients, interventions that include nonmusic sounds have not been addressed in reviews of evidence. It is unclear if nonmusic sounds in the intensive care unit (ICU) can confer benefits similar to those of music.

Objective: The aim of this study was to summarise and contrast available evidence on the effect of music and nonmusic sound interventions for the physiological and psychological outcomes of ICU patients based on the results of randomised controlled trials.

Introduction: Women with early bilateral salpingo-oophorectomy (BSO) have greater Alzheimer's disease (AD) risk than women with spontaneous menopause (SM), but the pathway toward this risk is understudied. Considering associative memory deficits may reflect early signs of AD, we studied how BSO affected brain activity underlying associative memory.

Methods: Early midlife women with BSO (with and without 17β-estradiol therapy [ET]) and age-matched controls (AMCs) with intact ovaries completed a face-name associative memory task during functional magnetic resonance imaging.

Introduction: Urinary incontinence is associated with social isolation, deconditioning, depression, falls and early mortality. It impairs quality of life, even in residents of nursing homes, and, in the community, increases the risk of institutionalisation. Care focused on the preservation of dignity during intimate care is important in the care of older adults.

Background: Abnormalities in effort-based decision-making have been consistently reported in major depressive disorder (MDD). Evidence indicates that metabolic factors, such as insulin resistance and dyslipidemia, which are highly prevalent in MDD, are independently associated with reward disturbances. Herein, we investigate the moderating effect of metabolic factors on effort-based decision-making in individuals with MDD.

Background & Aims: The Crohn's Disease (CD) Exclusion Diet (CDED)+Partial Enteral Nutrition (PEN) is effective for inducing remission in mild-moderate CD. We assessed whether a 2-week course of Exclusive Enteral Nutrition (EEN), followed by CDED+PEN is superior to 8 weeks of EEN in sustaining clinical remission at week 14 in mild-to-severe CD and if CDED+PEN can maintain remission to week 24.

Methods: This international, multicenter, randomized-controlled trial compared 2-weeks of EEN (Modulen®IBD) followed by 3 phases of the CDED+PEN (henceforth CDED) to 8 weeks of EEN, followed by PEN with free diet up to week 24 (henceforth EEN).
