THE IMPACTS OF HONEY BEE QUEEN STRESS ON WORKER BEHAVIOR AND HEALTH

Pesticides, poor nutrition, parasites and diseases work synergistically to contribute to the decline of the honey bee. Heritable sub-lethal behavior/immune effects may also contribute to the decline. Maternal stress is a common source of heritable immune/behavior deficits in many species. A stressed honey bee queen has the potential to pass such deficits on to worker bees. Using a repeated measures design, this study will determine whether the health of worker bee is reduced by a cold stress on the queen by analyzing egg hatch rate and protein content, emergence rate, and adult aggression and immune function for offspring laid before and after the stressor. Results show that queen stress influences egg hatching rate and emergence rate but does not impact egg protein content, adult offspring immune function or aggressive behavior

Computer Interactive Reminiscence and Conversation Aid groups – delivering cognitive stimulation with technology

INTRODUCTION: Group-based cognitive stimulation is the only nonpharmacological intervention recommended by the UK National Institute for Clinical and Health Excellence (NICE) for people with dementia. The potential of technology to extend the availability of group-based cognitive stimulation has not been tested. METHOD: One hundred and sixty-one people with dementia participated in an 8-session group activity using Computer Interactive Reminiscence and Conversation Aid (CIRCA). Cognition, quality of life and general health were assessed pre-, post- and three-months later. RESULTS: There was a significant improvement in cognition and quality of life at the end of the CIRCA group intervention, which was further improved at three-month follow-up. CONCLUSION: CIRCA group sessions improved cognition and quality of life similar to group-base cognitive stimulation approved by NICE. These benefits were maintained at three-month follow-up. The data confirm the potential of CIRCA, which can be populated with different cultural and language contents for different user groups

Early modern Oxford bindings in twenty-first century markup

Purpose – The Bodleian Binders Book contains nearly 150 pages of seventeenth century library records, revealing information about the binders used by the library and the thousands of bindings they produced. The purpose of this paper is to explore a pilot project to survey and record bindings information contained in the Binders Book. Design/methodology/approach – A sample size of seven pages (91 works, 65 identifiable bindings) to develop a methodology for surveying and recording bindings listed in the manuscript. To create a successful product that would be useful to bindings researchers, it addressed questions of bindings terminology and the role of the library in the knowledge creation process within the context that text encoding is changing the landscape of library functions. Text encoding formats were examined, and a basic TEI (Text Encoding Initiative) transcription was produced. This facilitates tagging of names and titles and the display of transcriptions with text images. Findings – Encoding was found not only to make the manuscript content more accessible, but to allow for the construction of new knowledge: characteristic Oxford binding traits were revealed and bindings were matched to binders. Plans for added functionality were formed. Originality/value – This research presents a “big picture” analysis of Oxford bindings as a result of text encoding and the foundation for qualitative and statistical analysis. It exemplifies the benefits of interdisciplinary methods – in this case from Digital Humanities – to enhance access to and interpretation of specialist materials and the library's provenance record

The immune response to nematode infection

Nematode infection is a major threat to the health of humans, domestic animals and wildlife. Nematodes vary in their effect on the host and in the mechanisms underlying immunity but the general features are becoming clear. There is considerable variation among individuals in resistance to infection and much of this variation is due to genetic variation in the immune response. The major histocompatibility complex has a strong influence on resistance to infection but other genes are collectively more important. Resistant individuals produce more IgA, eosinophils, IgE and mast cells than susceptible individuals and this is a consequence of stronger type 2 (Th2) immune responses. A variety of factors promote Th2 responses including genetic background, diet, molecules produced by the parasite and the location of the infection. A variety of cells and molecules including proteins, glycolipids and RNA act in concert to promote responses and to regulate the response. Nematodes themselves also modulate the host response and over 20 parasite-derived immunomodulatory molecules have been identified. Different species of nematodes modulate the immune response in different ways and probably use multiple molecules. The reasons for this are unclear and the interactions among immunomodulators have still to be investigated. © 2023 by the authors

Increasing Student Confidence in Writing: Integrating Authentic Manuscript Writing into an Online 8-Week Research Program

In various formats, students at the secondary and postsecondary levels participate in multiweek authentic science research projects. There have been many papers explaining the operations of such programs, but few have provided explicit instruction on how to incorporate authentic communication practices into the student research process. In this paper, we describe how we integrated primary literature into an 8-week online research program for 8th to 11th graders. Each week, students were introduced to a specific section of a primary research article reflecting different stages of their research project, and they were guided on how to write that specific section for their own research paper. By the end of the program, students had an outline or first draft of a primary research paper based on their research. Following completion of the program, student participants reported greater self-efficacy and confidence in scientific writing. Here, we describe our approach and provide an adaptable framework for integrating primary literature into research projects

Quantifying the sources of variation in eosinophilia among Scottish blackface lambs with mixed, predominantly Teladorsagia circumcincta nematode infection

Eosinophils play a key role in defence against gastrointestinal nematodes. There is considerable variation among animals in the intensity of eosinophilia following nematode infection. However, the statistical distribution of eosinophils among animals has still to be determined. A better description of the variation among animals could provide biological insight and determine the most appropriate way to analyse the effect of eosinophils. We estimated blood eosinophil numbers in a flock of Scottish Blackface sheep that were naturally exposed to mixed, predominantly Teladorsagia circumcincta infection. Three of the four eosinophil counts were better described by a gamma distribution than by a lognormal distribution. The scale and shape parameters of the gamma distribution varied over time. Eosinophil counts differed among animals kept on separate fields before weaning and between singletons and twins but were not significantly different between years and genders. Eosinophil counts also differed among offspring from different sires and dams. The parameters of the gamma distribution were used to enable a power analysis. Large numbers of animals were required to reliably detect even large differences between two groups. These results indicate that methods appropriate for gamma distributions, such as generalized linear mixed models, will provide more reliable inferences than traditional methods of analysis and experimental design. © 2021 The Author(s). **Please note that there are multiple authors for this article therefore only the name of the first 5 including Federation University Australia affiliate “David Piedrafita and Sarah Preston” is provided in this record*

The oligomeric assembly of galectin-11 is critical for anti-parasitic activity in sheep (Ovis aries)

Galectins are a family of glycan-binding molecules with a characteristic affinity for ß-D-glycosides that mediate a variety of important cellular functions, including immune and inflammatory responses. Galectin-11 (LGALS-11) has been recently identified as a mediator induced specifically in animals against gastrointestinal nematodes and can interfere with parasite growth and development. Here, we report that at least two natural genetic variants of LGALS-11 exist in sheep, and demonstrate fundamental differences in anti-parasitic activity, correlated with their ability to dimerise. This study improves our understanding of the role of galectins in the host immune and inflammatory responses against parasitic nematodes and provides a basis for genetic studies toward selective breeding of animals for resistance to parasites. © 2020, The Author(s). **Please note that there are multiple authors for this article therefore only the name of the first 5 including Federation University Australia affiliate “Dhanasekaran Sakthivel, Sarah Preston, Robin Gasser, Els Meeusen, David Piedrafita” is provided in this record*
