Exploring the Experiences of Visiting Veterinary Service Providers in Indigenous Communities in Canada: Proposing Strategies to Support Pre-Clinical Preparation.

Many Indigenous communities in Canada lack access to veterinary services due to geography, affordability, and acceptability. These barriers negatively affect the health of animals, communities, and human-animal relationships. Canadian veterinary colleges offer veterinary services to Indigenous communities through fourth-year veterinary student rotations.

Supporting Positive Learning Experiences for Veterinary Students on Rotations in Remote Indigenous Communities in Canada.

Many health care programs in medicine, nursing, social work, and physiotherapy include practicum rotations near the end of students' studies. Increasingly, veterinary education programs also offer community-based rotations in underserved or remote communities. While these opportunities in veterinary medicine provide many learning benefits, they can also be stressful if the students do not feel adequately supported.

Are we asking the right questions? Female athletes' perspectives on the menstrual cycle in sport.

Background: Menstrual cycle (MC) research employing qualitative and quantitative methods has recently increased in athlete populations. A move towards a participant-centered approach to help formulate questions that align with practitioners' and stakeholders' priorities in the sport environment is needed. Therefore, our study aims were to 1) understand what athletes feel is important to consider regarding their MC in sport, and 2) provide practical recommendations for coaches and practitioners to support a positive sport culture around the MC.

Continuum Mechanics Applied to the Biomechanics of Motion.

Continuum mechanics is the discipline that studies the motion and deformation of material bodies and is at the basis of both solid mechanics and fluid mechanics. This work aims at highlighting how a basic education in modern continuum mechanics can be of fundamental importance not only in the biomechanics of tissue but also in the biomechanics of movement. The latter is largely based on rigid body mechanics, which can be considered as a simple particular case of the general theory of continuum mechanics.

Synthesis of an Ethylenediaminetetraacetic Acid-like Ligand Based on Sucrose Scaffold and Complexation and Proton Relaxivity Studies of Its Gadolinium(III) Complex in Solution.

Sucrose constitutes a non-toxic, biodegradable, low-cost and readily available natural product. To expand its utility, we developed total synthesis for a ligand based on a sucrose scaffold for potential use as a metal chelation agent. The designed target (compound ) has a metal-chelating functionality at both the C-6 and C-6' positions, which can provide a first coordination sphere of eight valencies.

The emerging application of LC-based metallomics techniques to unravel the bioinorganic chemistry of toxic metal(loid)s.

The on-going anthropogenic emission of toxic metal(loid) species into the environment contaminates the food supply and drinking water resources in various parts of the world. Given that inorganic pollutants cannot be degraded, their increased influx into the bloodstream of babies, children and pregnant women is inevitable. Since the ramifications of the ensuing environmental exposure on human health remain poorly defined, fundamentally new insight into their bioinorganic chemistry in organisms is urgently needed.

Unprecedented Cubic Mesomorphic Behaviour of Crown-Ether Functionalized Amphiphilic Cyclodextrins.

Amphiphilic supramolecular materials based on biodegradable cyclodextrins (CDs) have been known to self-assemble into different types of thermotropic liquid crystals, including smectic and hexagonal columnar mesophases. Previous studies on amphiphilic CDs bearing 14 aliphatic chains at the secondary face and 7 oligoethylene glycol (OEG) chains at the primary face showed that the stability of the mesophase can be rationally tuned through implementation of terminal functional groups to the OEG chains. Here, we report the syntheses of first examples of crown ether-functionalized amphiphilic cyclodextrins that unexpectedly form thermotropic bicontinuous cubic phases.

Mobilizing strategic inflection points for sustainment of an effective intervention in an integrated learning health system: an interpretive description.

Background: Innovative models of care have the potential to improve the sustainability of health systems by improving patient and provider experiences and population outcomes while simultaneously reducing costs. Yet, it is challenging to recognize the distinctive points during research and quality improvement processes that contribute to sustainment of effective interventions. The business concept of an inflection point-the position on the curve of a trajectory where the progress in implementation of an intervention is accelerated or decelerated-may be useful to understand implementation and improve sustainability and ultimately sustainment of effective interventions.

Long-term Evaluation of Machine Learning Based Methods for Air Emission Monitoring.

Machine learning (ML) techniques have been researched and used in various environmental monitoring applications. Few studies have reported the long-term evaluation of such applications. Discussions regarding the risks and regulatory frameworks of ML applications in environmental monitoring have been rare.

Reconsidering assumptions in the analysis of muscle fibre cross-sectional area.

Cross-sectional area (CSA) is a fundamental variable in characterizing muscle mechanical properties. Typically, the CSA of a single muscle fibre is assessed by measuring either one or two diameters, and assuming the cross-section is either circular or elliptical in shape. However, fibre cross-sections have irregular shapes.

Substitutional Cu doping at the cation sites in Ba2YNbO6 toward improved visible-light photoactivity-A first-principles HSE06 study.

Artificial photosynthesis holds immense promise for sustainable clean energy harvesting, with recent strides in material engineering with the earth abundant elements enabling efficient utilization of the visible solar spectrum for photoelectrochemical catalytic water splitting. Here, we have investigated the impact of substitutional Cu doping at all three cation sites in Ba2YNbO6 (BYN) using density functional theory calculations at the Heyd-Scuseria-Ernzerhof-06 level. One of the key findings is that the defect formation energy follows the hierarchy Nb > Ba > Y.

A geospatial approach to identifying and mapping areas of relative environmental pressure on ecosystem integrity.

The influence of increasing anthropogenic pressure on ecosystem integrity, such as land use change, is resulting in many ecosystems experiencing a decline in their ability to maintain balanced functions and services. Identifying and quantifying these pressures over different scales is challenging and thus impacting the achievement or maintenance of key environmental outcomes. In this study, a GIS-based and scalable tool was developed, the Relative Environmental Pressure (REP) Tool, to address these challenges.

Microbial dietary preference and interactions affect the export of lipids to the deep ocean.

Lipids comprise a significant fraction of sinking organic matter in the ocean and play a crucial role in the carbon cycle. Despite this, our understanding of the processes that control lipid degradation is limited. We combined nanolipidomics and imaging to study the bacterial degradation of diverse algal lipid droplets and found that bacteria isolated from marine particles exhibited distinct dietary preferences, ranging from selective to promiscuous degraders.

Denitrification genotypes of endospore-forming .

Denitrification is a key metabolic process in the global nitrogen cycle and is performed by taxonomically diverse microorganisms. Despite the widespread importance of this metabolism, challenges remain in identifying denitrifying populations and predicting their metabolic end-products based on their genotype. Here, genome-resolved metagenomics was used to explore the denitrification genotype of enriched in nitrate-amended high temperature incubations with confirmed NO and N production.
