    Cooperative variety trials were conducted at 33 locations to determine field, storage, and processing behavior of selected potato clones and varieties when grown under soil, climatic, and cultural conditions common to the potato growing areas of 12 cooperating States and the Province of New Brunswick, Canada. These trials are all contributions to Regional Project NE107 entitled, Breeding and Evaluation of New Potato Clones in the Northeast Area.https://digitalcommons.library.umaine.edu/aes_bulletin/1123/thumbnail.jp

    The Unseeing Eye: Disability and the hauntology of Derrida’s ghost. A story in three parts

    Get PDF
    Through the employment of the three stanzas of Thomas Hardy’s poem ‘The Self-Unseeing’ this paper seeks to tremble the picture of disability located in the pedagogical materials in English Schools. By mobilising, and then reversing, Derrida’s concept of the visor and the ghost, as well as Bentham’s Panopticon, this story reveals the power of the Them, the Their and the They. In materialising the ghost of the real of disability within a utopia of hope this story deconstructs the power of Their transparent house by revealing disabled people as magnificent beings

    basic conducting, nonverbal conducting behaviors, conducting effectivenessThe purpose of this study was to examine undergraduate conductors’ and conducting teachers’ perceptions about basic conducting efficacy. At the beginning and end of the semester, undergraduate students (N = 19) enrolled in a basic conducting course (a) were surveyed about the importance of certain skills necessary for being an effective conductor and (b) viewed and rated their first videotaped conducting episode. Results indicated very few significant differences in participants’ ratings of important conducting skills or their own self-evaluation of nonverbal conducting skills. In addition, university conducting teachers (N = 9) evaluated videos of 10 conductors (five who had participated in the basic conducting course and five nonconductors who had not) who led a university concert band in an identical 1-minute excerpt of band music. No significant differences were found between the basic conductors and the nonconductors’ nonverbal conducting behaviors. Implications for conducting teachers, undergraduate conducting students, and preservice teachers are discussed.YesReviewed and accepted for publication in "Update: Applications of Research in Music Education" http://upd.sagepub.com/content/early/2014/10/23/8755123314554809.abstrac

    Transplantation elicits a clonally diverse CD8+ T cell response that is comprised of potent CD43+ effectors

    Summary: CD8+ T cells mediate acute rejection of allografts, which threatens the long-term survival of transplanted organs. Using MHC class I tetramers, we find that allogeneic CD8+ T cells are present at an elevated naive precursor frequency relative to other epitopes, only modestly increase in number after grafting, and maintain high T cell receptor diversity throughout the immune response. While antigen-specific effector CD8+ T cells poorly express the canonical effector marker KLRG-1, expression of the activated glycoform of CD43 defines potent effectors after transplantation. Activated CD43+ effector T cells maintain high expression of the coreceptor induced T cell costimulator (ICOS) in the presence of CTLA-4 immunoglobulin (Ig), and dual CTLA-4 Ig/anti-ICOS treatment prolongs graft survival. These data demonstrate that graft-specific CD8+ T cells have a distinct response profile relative to anti-pathogen CD8+ T cells and that CD43 and ICOS are critical surface receptors that define potent effector CD8+ T cell populations that form after transplantation

    Comparative Analysis of Single-cell and Single-nucleus RNA-sequencing in a Rabbit Model of Retinal Detachment-related Proliferative Vitreoretinopathy

    Purpose: Proliferative vitreoretinopathy (PVR) is the most common cause of failure of retinal reattachment surgery, and the molecular changes leading to this aberrant wound healing process are currently unknown. Our ultimate goal is to study PVR pathogenesis by employing single-cell transcriptomics to dissect cellular heterogeneity. Design: Here we aimed to compare single-cell RNA sequencing (scRNA-seq)  and single-nucleus RNA-sequencing (snRNA-seq) of retinal PVR samples in the rabbit model. Participants: Unilateral induction of PVR lesions in rabbit eyes with contralateral eyes serving as controls. Methods: Proliferative vitreoretinopathy was induced unilaterally in Dutch Belted rabbits. At different timepoints after PVR induction, retinas were dissociated into either cells or nuclei suspension and processed for scRNA-seq or snRNA-seq. Main Outcome Measures: Single cell and nuclei transcriptomic profiles of retinas after PVR induction. Results: Single-cell RNA sequencing and snRNA-seq were conducted on retinas at 4 hours and 14 days after disease induction. Although the capture rate of unique molecular identifiers and genes were greater in scRNA-seq samples, overall gene expression profiles of individual cell types were highly correlated between scRNA-seq and snRNA-seq. A major disparity between the 2 sequencing modalities was the cell type capture rate, however, with glial cell types overrepresented in scRNA-seq, and inner retinal neurons were enriched by snRNA-seq. Furthermore, fibrotic Müller glia were overrepresented in snRNA-seq samples, whereas reactive Müller glia were overrepresented in scRNA-seq samples. Trajectory analyses were similar between the 2 methods, allowing for the combined analysis of the scRNA-seq and snRNA-seq data sets. Conclusions: These findings highlight limitations of both scRNA-seq and snRNA-seq analysis and imply that use of both techniques together can more accurately identify transcriptional networks critical for aberrant fibrogenesis in PVR than using either in isolation.
