Marginal Maximum Likelihood Estimation of Item Response Models in R
No full textItem response theory (IRT) models are a class of statistical models used by researchers to describe the response behaviors of individuals to a set of categorically scored items. The most common IRT models can be classified as generalized linear fixed- and/or mixed-effect models. Although IRT models appear most often in the psychological testing literature, researchers in other fields have successfully utilized IRT-like models in a wide variety of applications. This paper discusses the three major methods of estimation in IRT and develops R functions utilizing the built-in capabilities of the R environment to find the marginal maximum likelihood estimates of the generalized partial credit model. The currently available R packages ltm is also discussed.
Data on isoaspartylation of neuronal ELAVL proteins
No full textAbstractThis article contains experimental data examining the propensity of neuronal ELAVL proteins to become isoaspartylated. The data are related to the article “Isoaspartylation appears to trigger small cell lung cancer-associated autoimmunity against neuronal protein ELAVL4” (M.A. Pulido, M.K. DerHartunian, Z. Qin, E.M. Chung, D.S. Kang, A.W. Woodham, J.A. Tsou, R. Klooster, O. Akbari, L. Wang, W.M. Kast, S.V. Liu, J.J.G.M. Verschuuren, D.W. Aswad, I.A. Laird-Offringa, 2016) [1], in which it was reported that the N-terminal region of recombinant human ELAVL4 protein, incubated under physiological conditions, acquires a type of highly immunogenic protein damage. Here, we present Western blot analysis data generated by using an affinity-purified polyclonal rabbit antibody (raised against an N-terminal ELAVL4 isoaspartyl-converted peptide) to probe recombinant protein fragments of the other three members of the ELAVL family: the highly homologous neuronal ELAVL2 (HuB) and ELAVL3 (HuC), and the much less homologous ubiquitously expressed ELAVL1 (HuR)
Discovery of a single faint AGN in a large sample of z > 5 Lyman break galaxies
No full textAs part of a large spectroscopic survey of z > 5 Lyman break galaxies (LBGs), we have identified a single source which is clearly hosting an active galactic nucleus (AGN). Out of a sample of more than 50 spectroscopically confirmed R-band dropout galaxies at z∼ 5 and above, only J104048.6−115550.2 at z= 5.44 shows evidence for a high ionization potential emission line indicating the presence of a hard ionizing continuum from an AGN. Like most objects in our sample the rest-frame-UV spectrum shows the UV continuum breaking across a Lyα line. Uniquely within this sample of LBGs, emission from N V is also detected, a clear signature of AGN photoionization. The object is spatially resolved in Hubble Space Telescope (HST) imaging. This, and the comparatively high Lyα/N V flux ratio indicates that the majority of the Lyα (and the UV continuum longward of it) originates from stellar photoionization, a product of the ongoing starburst in the LBG. Even without the AGN emission, this object would have been photometrically selected and spectroscopically confirmed as a Lyman break in our survey. The measured optical flux (IAB= 26.1) is therefore an upper limit to that from the AGN and is of order 100 times fainter than the majority of known quasars at these redshifts. The detection of a single object in our survey volume is consistent with the best current models of high redshift AGN luminosity function, providing a substantial fraction of such AGN is found within luminous starbursting galaxies. We discuss the cosmological implications of this discovery
Molecular basis of gene-environment interactions in the pathogenesis of asthma and COPD
No full textThe origins of respiratory disease, such as asthma in childhood and COPD in later life are unclear. Maternal smoking during pregnancy and low birth weight is associated with increased risk of asthma, poor lung function in adults and COPD in old age. Exposure to oxidative stress and poor nutrition in utero is thought to cause damage to the lung and alter the normal course of lung development.Glutathione S-transferases (GST) are potent antioxidants. In this work, genetic polymorphisms that alter GST enzyme activity were genotyped in a family-based childhood asthma cohort (341 families, n = 1508) and analysed to investigate whether they alter the risk of developing asthma when individuals are exposed to environmental tobacco smoke. Real-time PCR based copy number variation methodology was developed to genotype the common gene deletion polymorphism of GSTT1 and GSTM1 genes, for other GST genes (GSTP1 and GSTO2) SNP haplotypes were constructed. A rare GSTO2 haplotype was negatively associated with asthma susceptibility, atopy severity, and FEV1 values. Asthmatic children with a GSTT1 gene deletion, or a common GSTP1 haplotype, developed more severe asthma compared to individuals with a GSTT1 gene or non-carriers of the GSTP1 haplotype. Total IgE levels were increased in GSTT1*0 individuals when exposed to tobacco smoke in early life, suggesting a gene-environment interaction. GSTO2 may be a shared susceptibility locus for asthma in childhood and COPD in later life.Animal models of maternal protein-restriction during pregnancy can induce hypertension, diabetes and endothelial dysfunction in offspring and in some of these models alterations to lung gene expression and lung architecture have been reported. This work established that a rat model of maternal dietary protein-restriction during pregnancy known to induce hypertension in the offspring, results in persistent alterations to the expression of genes in the lungs of adult offspring (120 days), including genes involved in glucocorticoid action (Hsd11b2), growth (Igf1 & 2 and Pcdh1) and alveolar development (Tp53). Lung microRNA expression profiles were also altered in response to exposure to protein restriction in utero. These findings suggest a role for nutritional programming in respiratory disease susceptibility in later life and a role for microRNAs in the study of the developmental origins of health and disease in general. Further work will include the investigation of epigenetic mechanisms that control nutritional programming in lungs of animals exposed to protein-restriction in utero.This work has demonstrated that GST polymorphism is a risk factor for childhood asthma and certain genotypes can offer some protection against the development of severe asthma. There was little evidence to suggest that GST polymorphism modulates the effects of smoke exposure in early life. In addition, we have demonstrated that maternal diets that are poor in nutrition could predispose her offspring to respiratory disease in later life by altering the course of normal lung development in early life or response to environmental stimuli in later life

No full textLisa Ward (University of Huddersfield) and Ron Laird (University of Ulster) will provide conference with an insight to selected themes from recent Work Integrated Learning conferences and symposia. Their dialogue will enable delegates to hear of developments and practice from around the world of co-operative education. Their observations should enable all delegates to evaluate aspects of their own practice within a wider international context and lead to improvement
Cancer cachexia: Rationale for the MENAC (Multimodal - Exercise, Nutrition and Anti-inflammatory medication for Cachexia) trial
No full textCancer cachexia is a multifactorial syndrome characterised by an ongoing loss of skeletal muscle mass that cannot be fully reversed by conventional nutritional support alone. Cachexia has a high prevalence in cancer and a major impact on patient physical function, morbidity and mortality. Despite the consequences of cachexia, there is no licensed treatment for cachexia and no accepted standard of care. It has been argued that the multifactorial genesis of cachexia lends itself to therapeutic targeting through a multimodal treatment. Following a successful phase II trial, a phase III randomised controlled trial of a multimodal cachexia intervention is under way. Termed the MENAC trial (Multimodal - Exercise, Nutrition and Anti-inflammatory medication for Cachexia), this intervention is based on evidence to date and consists of non-steroidal anti-inflammatory drugs and eicosapentaenoic acid to reduce inflammation, a physical exercise programme using resistance and aerobic training to increase anabolism, as well as dietary counselling and oral nutritional supplements to promote energy and protein balance. Herein we describe the development of this trial. Trial registration number: NCT02330926.</p
