Resampling the pool of genotypic possibilities: an adaptive function of sexual reproduction

Author(s): Hickey DA; Golding GB;

Background: Natural populations harbor significant levels of genetic variability. Because of this standing genetic variation, the number of possible genotypic combinations is many orders of magnitude greater than the population size. This means that any given population contains only a tiny fraction of all possible genotypic combinations. Results: We sho ...

Emotion regulation from infancy to toddlerhood: Individual and group trajectories of full-term and very-low-birthweight preterm infants

Author(s): Atkinson NH; Jean ADL; Stack DM;

Adaptive emotion regulation begins with infants operating jointly with their parents to regulate their emotions, which fosters the development of independent regulation. Little is known about when or how this transition occurs, or the impact of factors such as parental availability or premature birth status. The current study examined the use of self-soot ...

COVID-FACT: A Fully-Automated Capsule Network-Based Framework for Identification of COVID-19 Cases from Chest CT Scans

Author(s): Heidarian S; Afshar P; Enshaei N; Naderkhani F; Rafiee MJ; Babaki Fard F; Samimi K; Atashzar SF; Oikonomou A; Plataniotis KN; Mohammadi A;

The newly discovered Coronavirus Disease 2019 (COVID-19) has been globally spreading and causing hundreds of thousands of deaths around the world as of its first emergence in late 2019. The rapid outbreak of this disease has overwhelmed health care infrastructures and arises the need to allocate ...

Blocking utilization of major plant biomass polysaccharides leads Aspergillus niger towards utilization of minor components

Author(s): Kun RS; Garrigues S; Di Falco M; Tsang A; de Vries RP;

Fungi produce a wide range of enzymes that allow them to grow on diverse plant biomass. Wheat bran is a low-cost substrate with high potential for biotechnological applications. It mainly contains cellulose and (arabino)xylan, as well as starch, proteins, lipids and lignin to a lesser extent. In this study, we dissected the regulatory network governing wh ...

Clustering of Unhealthy Behaviors: Protocol for a Multiple Behavior Analysis of Data From the Canadian Longitudinal Study on Aging

Author(s): van Allen Z; Bacon SL; Bernard P; Brown H; Desroches S; Kastner M; Lavoie K; Marques M; McCleary N; Straus S; Taljaard M; Thavorn K; Tomasone JR; Presseau J;

<strong>Background:</strong> Health behaviors such as physical inactivity, unhealthy eating, smoking tobacco, and alcohol use are leading risk factors for noncommunicable chronic diseases and play a central role in limiting health and life satisfaction. To date, however, health behavi ...

Characterizing white matter alterations subject to clinical laterality in drug-naïve de novo Parkinson's disease

Author(s): Xiao Y; Peters TM; Khan AR;

Parkinson's disease (PD) is a progressive neurodegenerative disorder that is characterized by a range of motor and nonmotor symptoms, often with the motor dysfunction initiated unilaterally. Knowledge regarding disease-related alterations in white matter pathways can effectively help improve the understanding of the disease and propose targeted treatm ...

Data-driven beamforming technique to attenuate ballistocardiogram artefacts in electroencephalography-functional magnetic resonance imaging without detecting cardiac pulses in electrocardiography recordings

Author(s): Uji M; Cross N; Pomares FB; Perrault AA; Jegou A; Nguyen A; Aydin U; Lina JM; Dang-Vu TT; Grova C;

Simultaneous recording of electroencephalography (EEG) and functional magnetic resonance imaging (fMRI) is a very promising non-invasive neuroimaging technique. However, EEG data obtained from the simultaneous EEG-fMRI are strongly influenced by MRI-related artefacts, namely gradient artefacts (G ...

Depressive Symptoms and Social Context Modulate Oxytocin's Effect on Negative Memory Recall

Author(s): Wong SF; Cardoso C; Orlando MA; Brown CA; Ellenbogen MA;

Oxytocin promotes social affiliation across various species, in part by altering social cognition to facilitate approach behaviour. However, the effects of intranasal oxytocin on human social cognition are mixed, perhaps because its effects are context-dependent and subject to inter-individual differences. Few studies have included explicit manipulations ...

Simple, scalable mechanosynthesis of metal-organic frameworks using liquid-assisted resonant acoustic mixing (LA-RAM)

Author(s): Titi HM; Do JL; Howarth AJ; Nagapudi K; Frišcic T;

We present a rapid and readily scalable methodology for the mechanosynthesis of diverse metal-organic frameworks (MOFs) in the absence of milling media typically required for other types of mechanochemical syntheses. We demonstrate the use of liquid-assisted resonant acoustic mixing (LA-RAM) methodology for the synthesis of three- and two-dimensional MOFs ...

Disturbance-induced emigration: an overlooked mechanism that reduces metapopulation extinction risk

Author(s): Mestre A; Barfield M; Peniston JH; Peres-Neto PR; Mesquita-Joanes F; Holt RD;

Emigration propensity (i.e., the tendency to leave undisturbed patches) is a key life-history trait of organisms in metapopulations with local extinctions and colonizations. Metapopulation models of dispersal evolution typically assume that patch disturbance kills all individuals within the patch, thus causing local extinction. However, individuals may in ...

Developing a collaborative and sustainable return to work program for employees with common mental disorders: a participatory research with public and private organizations

Author(s): Corbière M; Mazaniello-Chézol M; Lecomte T; Guay S; Panaccio A;

Purpose: To disentangle the key steps of the return to work (RTW) process and offer clearer recovery-focused and sustainable RTW for people on sick leave due to common mental disorders (CMDs). Methods: This participatory research involves two large Canadian organizations. In each organization, we established an advisory committee composed of RTW stakehol ...
