    No full text
    The churchwardens’ accounts for the City of London church of St. Mary-at-Hill (P69/MRY4/B/005/MS01239/001-002) are extensive for the period 1420-1558 and provide a wealth of evidence for the cultural life of the parish. They show that during the first half of the 16th century, the parish was both wealthy and musically advanced, with the church engaging a number of musicians in this period who later became significant figures, including the composer Thomas Tallis (c.1505–1585). This article provides a brief examination of the church’s choir school which was developed by the conductor, organist and master of the choir boys, John Northfolke during the 1520s

    A study in sixteenth-century performance and artistic networks: British Library, Additional Manuscript 15233

    No full text
    This thesis is a modern spelling edition of unedited poems and song lyrics from British Library, Additional Manuscript 15233, and a cultural and sociological study of the collection.The manuscript contains music, poetry and fragments of drama attributed to John Redford, Organist, Almoner and Master of the Choristers at St. Paul's Cathedral c.1534–1547, as well as work by at least six other mid Tudor poets. The manuscript has systematically been cited as a ‘St. Paul’s miscellany’(because the main body of work within it is attributed to Redford), and despite its varied content, has been considered almost solely from the perspective of Early Modern drama. This thesis considers the manuscript anew: as a whole, rather than in parts divided along disciplinary lines, as an example of material culture, and separately from the well-researched centres of St. Paul’s and John Redford.Chapters one and two comprise a study of the physical makeup of the manuscript, demonstrating new evidence for its date, and suggesting that it is the product of an artistic network centred on the London parish church of St. Mary-at-Hill.Chapters three and four comprise new studies of the content of the manuscript. Chapter three examines The Play of Wit and Science, with particular attention to its bibliographical status, and its engagement with contemporary artistic debate in performance. It also demonstrates its importance as a source for two later sixteenth-century plays. Chapter four is a case study of a single poem from the manuscript. This demonstrates the overall significance of MS 15233 as a source for verse and song, uncovers a network of printers involved in the transmission of its contents, and calls into question the long-standing theory that the Elizabethan poet George Gascoigne was a contributor to the manuscript.The final chapter of the thesis comprises a modern spelling edition of the poems and song lyrics from MS 15233 with individual commentaries and textual apparatus. This thesis demonstrates that to examine MS 15233 purely in relation to St. Paul’s Cathedral and John Redford, and from any one perspective, is reductive, and that these approaches have caused evidence to be skewed, and scholars to miss more complex possibilities regarding its compilation and provenance

    The present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed

    Ophthalmology. 2005 Feb;112(2):208-18; discussion 219. Mitomycin C modulation of corneal wound healing after photorefractive keratectomy in highly myopic eyes. Gambato C, Ghirlando A, Moretto E, Busato F, Midena E. SourceRefractive Surgery Service and Antimetabolite Therapy Research Unit, Department of Ophthalmology, University of Padova, Padova, Italy. Abstract PURPOSE: To evaluate the role of topical mitomycin C in corneal wound healing (CWH) after photorefractive keratectomy (PRK) in highly myopic eyes. DESIGN: Prospective, double-masked, randomized clinical trial. PARTICIPANTS: Seventy-two eyes of 36 patients affected by high (>7 diopters) myopia. METHODS: In each patient, one eye was randomly assigned to PRK with intraoperative topical 0.02% mitomycin C application, and the fellow eye was treated with a placebo. Postoperatively, mitomycin C-treated eyes received artificial tears (3 times daily, tapered in 3 months), whereas the fellow eye was treated with fluorometholone sodium 2% and artificial tears (3 times daily, tapered in 3 months). MAIN OUTCOME MEASURES: Uncorrected visual acuity (UCVA) and best-corrected visual acuity (BCVA), contrast sensitivity, manifest refraction, and biomicroscopy. Contrast sensitivity was determined using the Pelli-Robson chart. Corneal confocal microscopy documented CWH. RESULTS: Mean follow-up was 18 months (range, 12-36). No side effects or toxic effects were documented. At 12-month follow-up examination, UCVAs (logarithm of the minimum angle of resolution) were 0.4+/-0.48 and 0.5+/-0.53 (P = .03) in mitomycin C-treated eyes and corticosteroid-treated eyes, respectively. At 1 year, corneal haze developed in 20% of corticosteroid-treated eyes, versus 0% of mitomycin C-treated eyes. At 12, 24, and 36 months, corneal confocal microscopy showed activated keratocytes and extracellular matrix significantly more evident in untreated eyes (Ps = 0.004, 0.024, and 0.046, respectively). CONCLUSION: Topical intraoperative application of 0.02% mitomycin C can reduce haze formation in highly myopic eyes undergoing PRK. Comment in Ophthalmology. 2006 Feb;113(2):357; author reply 357-8

    Structures of microfilament destabilizing toxins bound to actin provide insight into toxin design and activity

    Marine macrolides that disrupt the actin cytoskeleton are promising candidates for cancer treatment. Here, we present the actinbound x-ray crystal structures of reidispongiolide A and C and sphinxolide B, three marine macrolides found among a recently discovered family of cytotoxic compounds. Their structures allow unequivocal assignment of the absolute configuration for each compound. A comparison of their actin-binding site to macrolides found in the trisoxazole family, as well as the divalent macrolide, swinholide A, reveals the existence of a common binding surface for a defined segment of their macrocyclic ring. This surface is located on a hydrophobic patch adjacent to the cleft separating domains 1 and 3 at the barbed-end of actin. The large area surrounding this surface accommodates a wide variety of conformations and designs observed in the macrocyclic component of barbed-end-targeting macrolides. Conversely, the binding pocket for the macrolide tail, located within the cleft itself, shows very limited variation. Functional characterization of these macrolides by using in vitro actin filament severing and polymerization assays demonstrate the necessity of the N-methyl-vinylformamide moiety at the terminus of the macrolide tail for toxin potency. These analyses also show the importance of stable interactions between the macrocyclic ring and the hydrophobic patch on actin for modifying filament structure and how this stability can be compromised by subtle changes in macrolactone ring composition. By identifying the essential components of these complex natural products that underlie their high actin affinity, we have established a framework for designing new therapeutic agents

    Dispelling the Myths Behind First-author Citation Counts

    We conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more sophisticated methods

    Prevalence and aetiology of neuropathic pain in cancer patients: a systematic review

    No full text
    Pain in cancer patients remains common and is often associated with insufficient prescribing of targeted analgesia. An explanation for undertreatment could be the failure to identify neuropathic pain mechanisms, which require additional prescribing strategies. We wanted to identify the prevalence of neuropathic mechanisms in patients with cancer pain to highlight the need for detailed assessment and to support the development of an international classification system for cancer pain. We searched for studies that included adult and teenage patients (age above 12 years), with active cancer and who reported pain, and in which a clinical assessment of their pain had been made. We found 22 eligible studies that reported on 13,683 patients. Clinical assessment methods varied, and only 14 studies reported confirmatory testing for either sensory abnormality or diagnostic lesion to corroborate a diagnosis of neuropathic pain. We calculated that the prevalence of patients with neuropathic pain (95% confidence interval) varied from a conservative estimate of 19% (9.4% to 28.4%) to a liberal estimate of 39.1% (28.9% to 49.5%) when patients with mixed pain were included. The prevalence of pain with a neuropathic mechanism (95% confidence interval) ranged from a conservative estimate of 18.7% (15.3% to 22.1%) to a liberal estimate of 21.4% (15.2% to 27.6%) of all recorded cancer pains. The proportion of pain caused by cancer treatment was higher in neuropathic pain compared with all types of cancer pain. A standardised approach or taxonomy used for assessing neuropathic pain in patients with cancer is needed to improve treatment outcomes

    A Multi-Language Comparison of Influences on Author Verification using Character N-Grams

    No full text
    We create a new multi-language corpus for author verification based on Wikipedia talkpages, and evaluate the influence that differences in topic and time have on character n-gram author profiles. Topic alignment between two texts is found to increase author verification precision, and an authors writing style is found to change over time, but not more significantly after 3 years than after 1 year.Information ArchitectureWISElectrical Engineering, Mathematics and Computer Scienc
