The ethics of exclusive submission: a narrative review of reciprocity in the author–journal relationship

Exclusive manuscript submission is a longstanding norm of scholarly publishing intended to protect finite peer-review resources, prevent duplicate publication and preserve the integrity of the scholarly record. While the ethical obligations required of authors are well establishe...

The Impact of Age and Physical Assessment Measures on Performance Among Non-Weightbearing Walking Aids: A Randomized Clinical Trial

Background: Walking aids for non-weightbearing (NWB) ambulation are often arbitrarily provided with no evidence that physical assessment predicts ambulatory performance. Purpose: We sought to determine if convenient physical assessment measures could guide NWB walking aid prescri...

On Horizontal Mergers in the Presence of Economies of Scale

Abstract This paper studies the conditions under which a profitable merger can simultaneously increase consumer surplus and total welfare. In Cournot markets with linear demand and concave-quadratic costs, greater economies of scale or more concave costs are associated with large...

A photogrammetry phenomic approach to quantifying canopy architecture traits in spring wheat

Canopy architecture refers to the arrangement of plant organs, leaves and shoots within a canopy and is an important plant trait which contributes to yield. High-throughput phenotyping has gained attention because of its high efficiency, quantitative and non-destructive method of...

Bioenergy potential of fast-growing trees, perennial grasses, and agricultural residues for renewable natural gas production in Canada

This study presents a comprehensive evaluation of fourteen lignocellulosic biomass feedstocks—including fast-growing trees (FGT: poplar, willow), perennial grasses (PG: switchgrass, miscanthus, phragmites), and agricultural residues (AR: hemp and canola straw)—to assess their pot...

Berberine as a Mitochondrial Metabolic Reprogrammer in Metabolic Dysfunction-Associated Steatotic Liver Disease (MASLD): Adaptive Energetic Stress, Quality Control, and Translational Limitations

Metabolic dysfunction-associated steatotic liver disease (MASLD) is closely linked to mitochondrial dysfunction, including altered oxidative phosphorylation, disrupted fatty-acid oxidation, redox imbalance, abnormal mitochondrial dynamics, and impaired quality control. Berberine...

Exploring Medical Professionals’ Perspectives on Cannabinoid Use in Professional and Elite-Level Contact Sports: A Qualitative Inquiry

BACKGROUND: The legalization and growing use of cannabis in elite sport raise concerns about the preparedness of sports medical staff, who often lack formal cannabinoid education and face regulatory, ethical, and communication challenges. HYPOTHESIS: Elite and professional contac...

An Emerging Omega-3 Fatty Acid—Octadecapentaenoic Acid (18:5n-3): Biosynthesis, Potential Sources and Applications

Octadecapentaenoic acid (OPA, 18:5n-3) is an emerging and poorly characterized omega-3 polyunsaturated fatty acid (PUFA) that is primarily produced by certain marine microalgae. Although it is structurally similar to the well-studied eicosapentaenoic acid (EPA, 20:5n-3) and docos...

Host‐mediated filtering and interspecific associations structure strongyle parasite communities in Sable Island horses

Mixed-species parasite infections are common in wildlife, yet the ecological processes that structure these communities remain poorly understood. We hypothesized that host-mediated and extrinsic environmental filtering, alongside biotic interactions, act concurrently to shape par...

Innate immune response to Streptococcus suis infection: advances and future challenges

Abstract Streptococcus suis is a pathogenic bacterium primarily found in pigs, where it causes sudden death and meningitis, but it is also capable of causing septic shock and meningitis in humans, being the most important cause of adult bacterial meningitis in Southeast Asia. As...

Performance Evaluation of Electrostatic Particle Ionization and Electro-Nanospray for Inlet Air Treatment in Livestock Facilities Under Controlled Conditions

Disease outbreaks impose substantial economic impacts on livestock production systems due to mortality, mandatory depopulation, reduced productivity, and additional costs associated with disease mitigation and biosecurity strategies. The introduction of viruses into commercial li...

Shared patterns of human milk composition link mammary gland function to infant growth

The mammary gland produces nutrient-rich human milk (HM), yet how mammary functional state shapes HM composition and infant outcomes remains poorly understood. We used HM multi-omics - metabolomics, proteomics, micronutrients, macronutrients, and HM oligosaccharides - across 1,54...

Ebselen Inactivates Essential Mycoplasmopsis bovis Proteins

Abstract Mycoplasmopsis bovis contributes to a variety of infectious diseases in cattle that limit meat and milk production, motivating significant antimicrobial use to prevent animal and economic loss. Currently approved antimicrobial treatments for M. bovis are ineffective or b...

Rail or river rivalry? Intermodal transportation of grain through Mississippi Corridors from 2002 to 2013

U.S. grain farming occurs predominantly throughout the vast Midwest. U.S. railroads as well as barges operating on the Mississippi River have played key roles in the regional grain supply chain. While research has been done about U.S. grain transportation, surprisingly little is...

Two-peakon dynamics in the Clifford algebra generalization of the Camassa–Holm equation

We study the dynamics of a two-component perturbation of the Camassa–Holm equation arising from a reformulation of the Euler–Bernoulli beam problem, recently extended to a general Clifford algebra setting. We focus on the original case associated with a Clifford algebra with two...

44. A Benchmark Study of Feeding and Management Practices, Feed Utilization, and Adoption of Growth-enhancing Technologies by the Canadian Feedlot Industry.

Abstract The Canadian feedlot industry is exceptionally diverse, in both operational practices and feeding management. Previous Canadian feedlot industry surveys lacked detailed information on feed ingredient usage, feeding management, and the use of growth and health enhancing t...

331. Growth Performance of Backgrounding Steers Fed a Diet with Continuous or Intermittent Inclusion of Ergot Alkaloids with and Without a Mycotoxin Deactivating Product.

Abstract This study evaluated the effect of feeding a backgrounding diet (60% barley silage:40% concentrate; DM basis) containing ergot alkaloids, with and without a mycotoxin-deactivating product (MDP), on the growth performance of feedlot steers. Crossbred steers (n = 360; 330...

Consistency between zonal mean stratospheric and total column ozone trends (2000–2024)

This study presents an updated assessment of stratospheric and total column ozone trends over the 2000–2024 period using six merged limb-profile datasets and six merged total ozone datasets. Long-term changes were quantified using a multiple linear regression framework that accou...

Agricultural practices as natural climate solutions in the Canadian Prairies

Management practices focused on environmental outcomes in agriculture can increase soil organic carbon (SOC) and reduce greenhouse gas (GHG) emissions, complementing farm production practices that provide food and a wide variety of other social-ecological services. However, evide...

Role of Na in determining the properties of sodic glasses

Molecular Dynamics (MD) simulation of Na 4 SiO 4 glass yields Na-O bond distances, and O-Na-O angles remarkably similar to those in sodic crystals, regardless of their compositions. Na polyhedra in both phases are stabilized by a common, formative mechanism, collapse of SiO 4 tet...
