Response to comment on "Human-specific gain of function in a developmental enhancer"

Duret and Galtier argue that human-specific sequence divergence and gain of function in the HACNS1 enhancer result from deleterious biased gene conversion (BGC) with no contribution from positive selection. We reinforce our previous conclusion by analyzing hypothesized BGC events genomewide and assessing the effect of recombination rates on human-accelerated conserved noncoding sequence ascertainment. We also provide evidence that AT → GC substitution bias can coexist with positive selection

Great Expectations: New Organizational Models for Overworked Liaisons Based on the UNCG Libraries Liaison Collections Responsibilities Task Force

Liaisons (subject specialists) keep getting busier. Research instruction, embedding in classes, outreach, collection development, weeding, assessing teaching and collections, promoting scholarly communication issues, and creating online learning objects are all potentially part of what a liaison is expected to do nowadays. So we hope every liaison is very interested—and very good—at all those responsibilities. Is that realistic? And does a liaison have time for all those things? At University of North Caroline at Greensboro (UNCG), library administrators decided it is time to examine how liaisons are organized to manage all of these competing responsibilities. The library formed a Liaison Collection Responsibilities Task Force to benchmark how other libraries might be handling the complexities of liaison responsibilities in innovative ways and to recommend several possible new organizational models for the collection development and public services work of liaisons. Members of the task force will review their benchmark findings and invite the audience to provide their own examples. Then we will present our recommendations for new organization models. Some recommendations will reflect incremental changes; others will be radical. We will ask the audience for feedback on the recommendations and suggestions for other models

Evaluating diabetes mobile applications for health literate designs and functionality, 2014

INTRODUCTION: The expansion of mobile health technologies, particularly for diabetes-related applications (apps), grew exponentially in the past decade. This study sought to examine the extent to which current mobile apps for diabetes have health literate features recommended by participants in an Institute of Medicine Roundtable and compare the health literate features by app cost (free or not). METHODS: We used diabetes-related keywords to identify diabetes-related apps for iOS devices. A random sample of 110 apps (24% of total number of apps identified) was selected for coding. The coding scheme was adapted from the discussion paper produced by participants in the Institute of Medicine Roundtable. RESULTS: Most diabetes apps in this sample addressed diabetes management and therapeutics, and paid apps were more likely than free apps to use plain language strategies, to label links clearly, and to have at least 1 feature (a “back” button) that helps with the organization. CONCLUSION: Paid apps were more likely than free apps to use strategies that should be more useful and engaging for people with low health literacy. Future work can investigate ways to make free diabetes mobile apps more user-friendly and accessible

Wound care challenges in children and adults with spina bifida: An open-cohort study

Skin breakdown is a frequent concern for individuals with spina bifida. We explored wound incidence in patients with spina bifida and how it varies across a person\u27s life span and functional neurologic level. We examined the settings in which skin breakdown most commonly occurred, looking for evidence of chronic, non-healing wounds. We also sought to develop criteria to improve wound monitoring. We identified reported wound episodes in an open-cohort study over a 13-year period, examining the hospital and outpatient clinical records of spina bifida patients at Children\u27s National Medical Center (CNMC). Current age, age at wound presentation, sex, weight, functional neurologic level, wound location, setting in which the wound was acquired, the development of a chronic wound, and presence of a shunt were recorded. Of the 376 patients in our clinical population, 123 (average age: 18.8 years, range: infancy–56 years) developed a total of 375 wounds; the majority of patients who developed one wound went on to develop one or more additional wounds, and 20 patients developed chronic wounds. Our data suggest that age bracket (adolescents), wheelchair use, and bare feet, as well as possibly obesity and reduced executive functioning, are key risk factors for wound development. These findings have led to a focused effort to increase wound education and prevention. In addition we report on our early experience using a wound care specialist to champion this initiative

More than skin deep: Functional genomic basis for resistance to Amphibian Chytridiomycosis

The amphibian-killing chytrid fungus Batrachochytriumdendrobatidis (Bd) is one of themost generalist pathogens known, capable of infecting hundreds of species globally and causing widespread population declines and extinctions. However, some host species are seemingly unaffected by Bd, tolerating or clearing infections without clinical signs of disease. Variation in host immune responses is commonly evoked for these resistant or tolerant species, yet to date,we have nodirect comparisonof amphibian species responses to infection at the level of gene expression. In this study,we challenged four CentralAmerican frog species that vary in Bd susceptibility, with a sympatric virulent strain of the pathogen. We compared skin and spleen orthologous gene expression using differential expression tests and coexpression gene network analyses.Wefound that resistant species have reduced skin inflammatory responses andincreased expressionofgenes involved inskin integrity. Incontrast, onlyhighly susceptible species exhibited suppressionof splenic T-cell genes. We conclude that resistance to chytridiomycosis may be related to a species’ ability to escape the immunosuppressive activity of the fungus. Moreover, our results indicate that within-species differences in splenic proteolytic enzyme gene expression may contribute to intraspecific variation in survival. This first comparison of amphibian functional immunogenomic architecture in response to Bd provides insights into key genetic mechanisms underlying variation in disease outcomes among amphibian species

Connecting Online Graduate Students to the University Community

The purpose of this study was to understand how to facilitate a sense of belonging among online graduate students. Sense of community theory was the basis for examining students’ desires to be a part of a community and feel connected to the institution. Findings from a survey using the Sense of Community Index 2 (SCI-2) of online graduate students provided insight into the sense of community, the importance of belonging to a community, and activities that could strengthen their connection with the institution. Overall students showed a slightly stronger sense of belonging to their program than to the institution. Students were also asked how they prefer to connect to others in the community with mentoring and inperson social events being the most requested

Quantifying the impact of avian influenza on the northern gannet colony of Bass Rock using ultra-high-resolution drone imagery and deep learning

Drones are an increasingly popular choice for wildlife surveys due to their versatility, quick response capabilities, and ability to access remote areas while covering large regions. A novel application presented here is to combine drone imagery with neural networks to assess mortality within a bird colony. Since 2021, Highly Pathogenic Avian Influenza (HPAI) has caused significant bird mortality in the UK, mainly affecting aquatic bird species. The world’s largest northern gannet colony on Scotland’s Bass Rock experienced substantial losses in 2022 due to the outbreak. To assess the impact, RGB imagery of Bass Rock was acquired in both 2022 and 2023 by deploying a drone over the island for the first time. A deep learning neural network was subsequently applied to the data to automatically detect and count live and dead gannets, providing population estimates for both years. The model was trained on the 2022 dataset and achieved a mean average precision (mAP) of 37%. Application of the model predicted 18,220 live and 3761 dead gannets for 2022, consistent with NatureScot’s manual count of 21,277 live and 5035 dead gannets. For 2023, the model predicted 48,455 live and 43 dead gannets, and the manual count carried out by the Scottish Seabird Centre and UK Centre for Ecology and Hydrology (UKCEH) of the same area gave 51,428 live and 23 dead gannets. This marks a promising start to the colony’s recovery with a population increase of 166% determined by the model. The results presented here are the first known application of deep learning to detect dead birds from drone imagery, showcasing the methodology’s swift and adaptable nature to not only provide ongoing monitoring of seabird colonies and other wildlife species but also to conduct mortality assessments. As such, it could prove to be a valuable tool for conservation purposes
