Case report: Surgical closure of a facial defect in an African wild dog () utilizing a transpositional skin flap.

Veterinary intervention in zoological species can be complicated by species-specific social dynamics. African wild dogs are a pack species and removal or separation of an individual may disrupt established pack hierarchy resulting in conspecific aggression. Therefore, medical interventions that optimize a quick return to health are ideal to minimize the duration of absence from the pack.

Slipping Through the Cracks? Concussion Management in Aotearoa New Zealand Secondary Schools.

Background: Concussion-related guidelines appear to be inconsistently implemented in secondary schools in Aotearoa New Zealand. The purpose of this qualitative Participatory Action Research study was to describe key school stakeholders' perceptions of their current concussion management processes.

Methods: Seventeen focus groups, two dyad, and nine individual interviews were conducted with stakeholders (n = 95) from six secondary schools and healthcare clinics, exploring their perceptions of barriers and facilitators to concussion management.

Quantifying Metagenomic Strain Associations from Microbiomes with Anpan.

Genetic and genomic variation among microbial strains can dramatically influence their phenotypes and environmental impact, including on human health. However, inferential methods for quantifying these differences have been lacking. Strain-level metagenomic profiling data has several features that make traditional statistical methods challenging to use, including high dimensionality, extreme variation among samples, and complex phylogenetic relatedness.

Native Point Defects Controlling Piezoelectric Voltage in Strained ZnO Microwires.

Piezovoltages generated by ZnO nano/microwire bending and strain enable electronic biogenerators that harvest human body movement to power-implanted biomedical devices. Currently, low voltages generated by these biogenerators limit their use to replace today's biomedical batteries. Electrically charged native point defects inside ZnO microwires can control these macroscopic piezo voltages, generating transverse electric fields that couple with strained wires' lengthwise piezoelectric fields so they redistribute spatially and change voltage output.

Alterations in whole muscle quality and physiological cross-sectional area measured with quantitative MRI following ACL injury.

Background: Emerging evidence suggests that there are morphological and physiological changes to the vastus lateralis after an anterior cruciate ligament (ACL) tear. However, it is unclear whether these alterations are limited to just the vastus lateralis or are more representative of widespread changes across the thigh musculature and/or if these changes precede reconstruction. The purpose of this study was to determine T1ρ relaxation time, a measure of extracellular matrix organization in muscle, and physiological cross-sectional area (PCSA) for muscles of the quadriceps and hamstrings of the ACL-deficient and contralateral limbs soon after ACL injury.
