Data from: Differing patterns of stress and craving across the day in moderate-heavy alcohol consumers during their typical drinking routine and an imposed period of alcohol abstinence

Rhiannon E. Mayhugh, W. Jack Rejeski, Meredith R. Petrie, Paul J. Laurienti & Lise Gauvin
Background: Stress is a known factor related to alcohol use. However, how the relationship between alcohol craving and stress varies across the day is not fully understood. As craving is a consistent predictor of alcohol use disorder (AUD), understanding stress and craving patterns across the day in routine, non-dependent, moderate-heavy alcohol consumers may help in understanding those who may be vulnerable to transitioning into AUD. Method: Moderate-heavy drinkers were recruited from the local community (n=32)...

Data from: Fast formation of a supramolecular ion gel/solvoplastic elastomer with excellent stretchability

ShiShun Bai, Xin Wang, Jaana Vapaavuori & Xianru He
This study describes a simple yet efficient approach for the preparation of an ionic gel that is also elastomeric in its solid state bulk form. A series of poly(2-(Diethylamino)ethyl methacrylate-co-Lauryl methacrylate) P(DMAEMA-co-LMA) copolymer were synthesized first by radical polymerization. Quaternization of the PDMAEMA component in THF enables the formation of supramolecular network, gave rise to an ion gel. An elastomer with an elongation at break of over 600 % was obtained from the gel. The...

Data from: Cardiac vagal dysfunction moderates patterns of craving across the day in moderate to heavy consumers of alcohol

Rhiannon E. Mayhugh, Paul J. Laurienti, Jason Fanning, Lise Gauvin, Keri J. Heilman, Stephen W. Porges & W. Jack Rejeski
Background: Alcohol craving, a known correlate of vulnerability to Alcohol Use Disorder (AUD), has been found to be inversely related to cardiac vagal tone (CVT). Here we examine how resting CVT, CVT reactivity to a postural challenge, and their interaction influence craving during imposed alcohol abstinence and their usual drinking among moderate to heavy drinkers. Methods: Participants were recruited from the local community (final n=29) and assessed for CVT functioning via respiratory sinus arrhythmia (RSA)...

Data from: Leaf nutrients, not specific leaf area, are consistent indicators of elevated nutrient inputs

Jennifer Firn, James M. McGree, Eric Harvey, Habacuc Flores-Moreno, Martin Schütz, Yvonne M. Buckley, Elizabeth T. Borer, Eric W. Seabloom, Kimberly J. La Pierre, Andrew M. MacDougall, Suzanne M. Prober, Carly J. Stevens, Lauren L. Sullivan, Erica Porter, Emma Ladouceur, Charlotte Allen, Karine H. Moromizato, John W. Morgan, W. Stanley Harpole, Yann Hautier, Nico Eisenhauer, Justin P. Wright, Peter B. Adler, Carlos Alberto Arnillas, Jonathan D. Bakker … & Anita C. Risch
Leaf traits are frequently measured in ecology to provide a ‘common currency’ for predicting how anthropogenic pressures impact ecosystem function. Here, we test whether leaf traits consistently respond to experimental treatments across 27 globally distributed grassland sites across 4 continents. We find that specific leaf area (leaf area per unit mass)—a commonly measured morphological trait inferring shifts between plant growth strategies—did not respond to up to four years of soil nutrient additions. Leaf nitrogen, phosphorus...

Data from: Valproic acid is protective in cellular and worm models of oculopharyngeal muscular dystrophy

Aida Abu-Baker, Alex Parker, Siriram Ramalingam, Janet Laganiere, Bernard Brais, Christian Neri, Patrick Dion & Guy Rouleau
Objective: To explore valproic acid (VPA) as a potentially beneficial drug in cellular and worm models of oculopharyngeal muscular dystrophy (OPMD). Methods: Using a combination of live cell imaging and biochemical measures, we evaluated the potential protective effect of VPA in a stable C2C12 muscle cell model of OPMD, in lymphoblastoid cell lines derived from patients with OPMD and in a transgenic Caenorhabditis elegans OPMD model expressing human mutant PABPN1. Results: We demonstrated that VPA...

Data from: Differential impacts of vaccination on wildlife disease spread during epizootic and enzootic phases

Erica J. Newton, Bruce A. Pond, Rowland R. Tinline, Kevin Middel, Denise Belanger & Erin E. Rees
1. Dissemination of oral vaccine baits is a cost-effective method to contain and control infectious wildlife diseases. The effectiveness of vaccine barriers in slowing or halting the disease spread depends on host ecology and landscape variability. It is not clear, however, how the success of vaccine barriers to manage disease may change from an epizootic to an enzootic phase of a disease invasion, and if this depends on the quality and configuration of host habitat....

Data from: Exploring an alternative explanation for the second phase of viral decay: infection of short-lived cells in a drug-limited compartment during HAART

Steven Sanche, Thibault Mesplède, Nancy Sheehan, Jun Li, Fahima Nekka & Nancy L. Sheehan
Most HIV-infected patients who initiate combination antiretroviral therapy experience a viral load decline in several phases. These phases are characterized by different rates of viral load decay that decrease when transitioning from one phase to the next. There is no consensus as to the origin of these phases. One hypothesis put forward is that short- and long-lived infected cells are responsible for the first and second phases of decay, respectively. However, significant differences in drug...

Data from: Data management, archiving and sharing for biologists and the role of research institutions in the technology-oriented age

Sebastien Renaut, Amber E. Budden, Dominique Gravel, Timothée Poisot & Pedro Peres-Neto
Data are one of the primary outputs of science. Although certain sub-disciplines of biology have pioneered efforts to ensure their long-term preservation and facilitate collaborations, data continue to disappear, owing mostly to technological, regulatory and ideological hurdles. In this review, we describe the important steps towards proper data management and archiving, and provide a critical discussion on the importance of long term data conservation. We then illustrate the rise in data archiving through the Joint...

Data from: Plasticity in root symbioses following shifts in soil nutrient availability during long-term ecosystem development

François P. Teste & Etienne Laliberté
1. The vast majority of terrestrial plants form root symbioses with arbuscular mycorrhizal (AM) fungi to enhance nutrient (particularly phosphorus, P) acquisition, but some plant species also form dual symbioses involving ectomycorrhizal (ECM) fungi, with a subset of those also forming triple symbioses also involving dinitrogen (N2)-fixing bacteria. Whether these plants show plasticity in root symbioses to optimise nutrient acquisition depending on the type and strength of soil nutrient limitation (e.g., N vs. P) has...
