Personalities, Preferences and Practicalities: Educating Nurses in Wound Sepsis in the British Hospital, 1870 – 1920

The history of nursing education has often been portrayed as the subordination of nursing to medicine. Yet, as scholars are increasingly acknowledging, the professional boundaries between medicine and nursing were fluid in the nineteenth and early twentieth centuries, when both scientific knowledge and systems of nurse training were in flux. Through its focus on the role of medical practitioners in educating nurses in wound sepsis at four British hospitals between 1870 and 1920, this article attempts to further unite histories of medicine and nursing. It demonstrates that, in this period of uncertainty, the ideas and practices relating to antisepsis, asepsis and bacteriology disseminated to nursing probationers depended on the individual instructor. In demonstrating the localised nature of nursing education, this article argues that further analyses of clinical problems like wound sepsis may enable historians to more clearly identify the importance of professional collaboration within the hospital

Pressure-induced polymorphism of caprolactam : a neutron diffraction study

Caprolactam, a precursor to nylon-6 has been investigated as part of our studies into the polymerization of materials at high pressure. Single-crystal X-ray and neutron powder diffraction data have been used to explore the high-pressure phase behavior of caprolactam and we have observed two new high pressure solid forms. The transition between each of the forms requires a substantial rearrangement of the molecules and we observe that the kinetic barrier to the conversion can aid retention of phases beyond their region of stability. Form II of caprolactam shows a small pressure region of stability between 0.5 and 0.9 GPa with Form III being stable from 0.9 GPa to 5.4 GPa. The two high-pressure forms have a catemeric hydrogen-bonding pattern compared with the dimer interaction observed in the ambient pressure Form I. The interaction between the chains has a marked effect on the directions of maximal compressibility in the structure. Neither of the high-pressure forms can be recovered to ambient pressure and there is no evidence of any polymerization occurring

Reaction of acetylenedicarboxylic acid made easy : high-pressure route for polymerization

A breakthrough has been achieved in improving the efficiency of solid-state polymerization of acetylenedicarboxylic acid (ADCA). Traditional solid state polymerization of ADCA is marked by long exposure times of γ-radiation (>10 days) and very low yields (around 5.5%). We have been able to perform a reaction to an n=8 oligomer, as confirmed by MALDI-TOF, in less than 2 minutes by employing ~6 GPa of pressure. We have determined the crystal structure of ADCA on increasing pressure to (5.2 GPa) to provide insight into the process of polymerization with Pixel calculations supporting our evaluation of the polymerization process

Voices from the past: early institutional experience of children with disabilities - the case of Scotland

In Scotland, public interest in children with disabilities followed an uneven path. The proponents for such interest included workers in medicine, education and training, public administration, law and order, religion and moral rectitude, philanthropy and charity. Their foci of attention were similarly divers. Initial attention towards children with ‘disabilities’ was directed towards those with sensory impairments. This was followed by provision for children with mental disabilities. Until the introduction of compulsory education in 1872, philanthropists and charities were largely unaware of children with physical impairments. The Scottish experience was distinctive from the rest of the United Kingdom because of its own legal system, and was set against a background of heavy industrialization accompanied by poverty and bad housing. Legislation in such areas as poor law reform and education was not introduced simultaneously to that for England and Wales. The Church of Scotland maintained a strong influence in local government, through the network of clearly defined parishes, despite the secularization that was intent in such legislation as the Poor Law (Scotland) Act of 1843. The influence of Presbyterian clergymen and church elders committed to strongly held ideals of religious belief, respectability and self-help is often apparent in the institutions established for children with disabilities. The following research makes use of archival sources on institutions receiving, accommodating and caring for children with disabilities, supplemented by some contemporary narrative and oral testimony. While the archival sources show that the attention paid to children with disabilities did not develop simultaneously for categories of impairment broadly grouped as sensory, mental and physical, they also indicate that the responses to different forms of disablement followed diverse approaches and objectives

Oralism: a sign of the times? The contest for deaf communication in education provision in late nineteenth-century Scotland

Disability history is a diverse field. In focussing upon children within deaf education in late nineteenth-century Scotland, this essay reflects some of that diversity. In 1880, the International Congress on the Education of the Deaf in Milan stipulated that speech should have ‘preference’ over signs in the education of deaf children. The mode of achieving this, however, effectively banned sign language. Endeavours to teach deaf children to articulate were not new, but this decision placed pressures on deaf institutions to favour the oral system of deaf communication over other methods. In Scotland efforts were made to adopt oralism, and yet educators were faced with the reality that this was not good educational practice for most pupils. This article will consider responses of Scottish educators of deaf children from the 1870s until the beginning of the twentieth century

FOXM1 Induces a Global Methylation Signature That Mimics the Cancer Epigenome in Head and Neck Squamous Cell Carcinoma

The oncogene FOXM1 has been implicated in all major types of human cancer. We recently showed that aberrant FOXM1 expression causes stem cell compartment expansion resulting in the initiation of hyperplasia. We have previously shown that FOXM1 regulates HELLS, a SNF2/helicase involved in DNA methylation, implicating FOXM1 in epigenetic regulation. Here, we have demonstrated using primary normal human oral keratinocytes (NOK) that upregulation of FOXM1 suppressed the tumour suppressor gene p16INK4A (CDKN2A) through promoter hypermethylation. Knockdown of HELLS using siRNA re-activated the mRNA expression of p16INK4A and concomitant downregulation of two DNA methyltransferases DNMT1 and DNMT3B. The dose-dependent upregulation of endogenous FOXM1 (isoform B) expression during tumour progression across a panel of normal primary NOK strains (n = 8), dysplasias (n = 5) and head and neck squamous cell carcinoma (HNSCC) cell lines (n = 11) correlated positively with endogenous expressions of HELLS, BMI1, DNMT1 and DNMT3B and negatively with p16INK4A and involucrin. Bisulfite modification and methylation-specific promoter analysis using absolute quantitative PCR (MS-qPCR) showed that upregulation of FOXM1 significantly induced p16INK4A promoter hypermethylation (10-fold, P<0.05) in primary NOK cells. Using a non-bias genome-wide promoter methylation microarray profiling method, we revealed that aberrant FOXM1 expression in primary NOK induced a global hypomethylation pattern similar to that found in an HNSCC (SCC15) cell line. Following validation experiments using absolute qPCR, we have identified a set of differentially methylated genes, found to be inversely correlated with in vivo mRNA expression levels of clinical HNSCC tumour biopsy samples. This study provided the first evidence, using primary normal human cells and tumour tissues, that aberrant upregulation of FOXM1 orchestrated a DNA methylation signature that mimics the cancer methylome landscape, from which we have identified a unique FOXM1-induced epigenetic signature which may have clinical translational potentials as biomarkers for early cancer screening, diagnostic and/or therapeutic interventions
