Dietary exposure of stormwater contaminants in biofilm to two freshwater macroinvertebrates.

Aquatic habitats in urban environments are exposed to complex contaminant mixtures that may harm aquatic biota. The impact of contaminant transfer from contaminated biofilm through aquatic food webs is still understudied, as is the current state of knowledge on dietary exposure of urban contaminants to biota residing in stormwater ponds. Our overall objective was to characterize urban pesticide accumulation in a common aquatic food source (biofilm) in stormwater ponds and to investigate the potential toxicity of that food source by testing the responses of two freshwater macroinvertebrates to experimental exposure.

Duality in disease: How two amino acid substitutions at actin residue 312 result in opposing forms of cardiomyopathy.

Two common types of cardiovascular disease are hypertrophic cardiomyopathy (HCM) and dilated cardiomyopathy (DCM) which occur from changes to sarcomere contractile mechanisms and activity. Actin amino acid substitutions R312C and R312H have been found in HCM and DCM patients, respectively. Previously, we observed that R312C/H variants display both hyperactivity and hypoactivity in vitro, contradicting traditional characterizations of HCM- and DCM-causing variants.

Partial coverage adhesive augmented sternal fixation and stabilization: A biomechanical analysis.

Adhesive-augmented sternal fixation (AASF) has been investigated as an alternative to the clinical standard of cerclage wires; however, previous studies have focused on a full adhesive layer across the sternal midline, which acts as a barrier to bone healing. This study used a human cadaveric model to investigate if partial coverage AASF used in combination with wired fixation could provide adequate stability. Median sternotomies were performed on fifteen human cadaveric sterna.

The Making of Everyday Space of Publicness: Insights from a Mall in Beijing.

The rise of malls in China raises questions about their roles as public spaces in Chinese cities. This article proposes the concept of everyday space of publicness to trace contextually sensitive ways that urban inhabitants make the mall a space for public life. The making of everyday space of publicness is evidenced using data from ethnographic fieldwork conducted in an inner-city open-air mall in Beijing.

The aim of this study was to develop an accessible and reusable ultrasound skill simulator for ultrasound guided centesis (USGC). Fifty second year veterinary students reviewed an instructional video prior to performing two USGC skill tests on the simulator, separated by a period of practice.

An Investigation of Veterinary College Websites in the US and Canada: Representations and Content of Equity, Diversity, and Inclusion.

University websites are often a first point of contact for prospective students. Portrayals of diversity on the website can influence current and future students' perceptions. Using content and statistical analysis, all 38 veterinary college websites in Canada and the US were systematically coded for representations of people in photos and content related to equity, diversity, and inclusion (EDI).

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.

Is Digital Video Recorded Simulated Suture Skills Testing Associated With Lower Stress and Anxiety Than Traditional In-Person Assessment for Veterinary Students?

Anxiety can affect exam performance so exploring methods to improve mental health and academic performance is relevant. The objectives of this study were to investigate stress amongst veterinary students undergoing simulated suture skills examinations and determine if digital video recording can reduce stress compared to in-person examination. Thirty-nine students were prospectively enrolled and randomized to undergo two simulated suture examinations, a session proctored by an in-person examiner or one digitally recorded with no proctor present and then crossed over to the other group.

A Benchmark Survey of the Delivery of Clinical Education in Small Animal Primary-Care Clinical Programs Among Member Institutions of the American Association of Veterinary Medical Colleges.

While primary-care clinical rotations are well established and have been incorporated into veterinary colleges over the past 50 years, standardization of teaching small animal primary care across veterinary colleges is unknown. The purpose of this study was to explore and document variations and similarities in the delivery of small animal primary-care clinical education curricula among member programs of the American Association of Veterinary Medicine Colleges (AAVMC). A comprehensive, 114-question online survey was conducted, comprising seven sections, including Rotation Logistics; House Officers; Procedures Performed; Rounds; Spectrum of Care; Diversity, Equity, and Inclusion; Assessment; Leadership Roles; and Research.

A Global Evaluation of Generic Antimicrobial Prescribing Competencies for Use in Veterinary Curricula.

The European Society for Clinical Microbiology and Infectious Diseases (ESCMID) developed consensus-based generic competencies in antimicrobial prescribing and stewardship. These may be useful in structuring and evaluating antimicrobial prescribing education to veterinary students, but their applicability has not been evaluated. We aimed to evaluate whether the ESCMID competencies are currently taught and how relevant they are to veterinary prescribing in veterinary schools globally.

A low-cost homogenizing device for in-field and remote DNA and RNA extraction.

Environmental monitoring of microorganisms is critical for the protection and enhancement of human and ecosystem health. Even though these molecular methods have overtaken traditional culture-based methods and become more accessible, these techniques still require expensive equipment and dedicated facilities to process samples which in the context of a global pandemic, remote sampling areas or low-income countries can be extremely challenging. Sample preparation and sample homogenisation are critical steps for molecular-based techniques, especially for the extraction of DNA and RNA.
