A patient with anti-NXP2-positive dermatomyositis and syphilis
Dermatomyositis is an auto-immune inflammatory myopathy that primarily affects the skin and muscle and can be triggered by exposure to various environmental factors. We present a patient with active syphilis infection who developed dermatomyositis and discuss the significance of anti-NXP2 autoantibody positivity
If Words Could Kill: Rhetorical Methodology in Media Depictions of Serial Killers
This thesis explores how the Canadian Broadcasting Corporation (CBC), a trusted national broadcaster, engages in implicit and particularly damaging rhetoric in The Fifth Estateâs âKarla Homolkaâ documentary to influence audiences into adopting a misleading impression of its conveyed message. Originally aired on November 25, 1997, the hour-long episode of CBCâs flagship television program, The Fifth Estate is dedicated to examining the Ontario Crown prosecutorsâ plea bargain with Karla Homolka. The Fifth Estateâs âKarla Homolkaâ from the CBC will serve as the primary rhetorical artefact with Geraldoâs âManson: Psychoâ from a syndicated network acting as a secondary rhetorical artefact and comparison point.
To understand the rhetorical processes in the respective episodes of The Fifth Estate and Geraldo, this thesis will conduct an analysis using (1) leadership theory by John P. Kotter and James MacGregor Burns, and (2) rhetorical criticism rooted in concepts provided by Lloyd Bitzer, Edwin Black, and Kenneth Burke. The leadership and rhetorical theories offer insight into identifying the context, motives, and patterns to critically analyze Geraldoâs âManson: Psychoâ as a baseline of defining sensationalism to contextualize with the sensational tactics in The Fifth Estateâs âKarla Homolkaâ episode.
To conclude, this thesis reveals how the leadership and rhetorical strategies enacted by the CBC undermine its own integrity in the documentary by inviting an audience to indulge in salacious entertainment, motivated less by a desire to understand a complex legal process than to be titillated by sensationalistic and fantastical narratives. The CBC manipulates and misdirects the audiencesâ attitudes, flirting with societal harm and public moral panic over a supposed threat that was disparate to its potential harm or actual danger

Young childrenâs food brand knowledge. Early development and associations with television viewing and parentâs diet
Brand knowledge is a prerequisite of childrenâs requests and choices for branded foods. We explored the development of young childrenâs brand knowledge of foods highly advertised on television â both healthy and less healthy. Participants were 172 children aged 3â5 years in diverse socio-economic settings, from two jurisdictions on the island of Ireland with different regulatory environments. Results indicated that food brand knowledge (i) did not differ across jurisdictions; (ii) increased significantly between 3 and 4 years; and (iii) children had significantly greater knowledge of unhealthy food brands, compared with similarly advertised healthy brands. In addition, (iv) childrenâs healthy food brand knowledge was not related to their television viewing, their motherâs education, or parent or child eating. However, (v) unhealthy brand knowledge was significantly related to all these factors, although only parent eating and childrenâs age were independent predictors. Findings indicate that effects of food marketing for un- healthy foods take place through routes other than television advertising alone, and are present before pre-schoolers develop the concept of healthy eating. Implications are that marketing restrictions of un- healthy foods should extend beyond television advertising; and that family-focused obesity prevention programmes should begin before children are 3 years of age
Catalysis in flow: Operando study of Pd catalyst speciation and leaching
A custom-made plug flow reactor was designed and constructed to examine the behaviour of Pd catalysts during Suzuki-Miyaura cross-coupling reactions. Spatial-temporal resolution of catalyst activation, deactivation and leaching processes can be obtained by single-pass experiments. Subsequent deployment of the flow reactor in a XAS beam line revealed speciation of Pd along the catalyst bed
The Circadian Clock Protein Timeless Regulates Phagocytosis of Bacteria in Drosophila
Survival of bacterial infection is the result of complex host-pathogen interactions. An often-overlooked aspect of these interactions is the circadian state of the host. Previously, we demonstrated that Drosophila mutants lacking the circadian regulatory proteins Timeless (Tim) and Period (Per) are sensitive to infection by S. pneumoniae. Sensitivity to infection can be mediated either by changes in resistance (control of microbial load) or tolerance (endurance of the pathogenic effects of infection). Here we show that Tim regulates resistance against both S. pneumoniae and S. marcescens. We set out to characterize and identify the underlying mechanism of resistance that is circadian-regulated. Using S. pneumoniae, we found that resistance oscillates daily in adult wild-type flies and that these oscillations are absent in Tim mutants. Drosophila have at least three main resistance mechanisms to kill high levels of bacteria in their hemolymph: melanization, antimicrobial peptides, and phagocytosis. We found that melanization is not circadian-regulated. We further found that basal levels of AMP gene expression exhibit time-of-day oscillations but that these are Tim-independent; moreover, infection-induced AMP gene expression is not circadian-regulated. We then show that phagocytosis is circadian-regulated. Wild-type flies exhibit up-regulated phagocytic activity at night; Tim mutants have normal phagocytic activity during the day but lack this night-time peak. Tim appears to regulate an upstream event in phagocytosis, such as bacterial recognition or activation of phagocytic hemocytes. Interestingly, inhibition of phagocytosis in wild type flies results in survival kinetics similar to Tim mutants after infection with S. pneumoniae. Taken together, these results suggest that loss of circadian oscillation of a specific immune function (phagocytosis) can have significant effects on long-term survival of infection
Finishing the euchromatic sequence of the human genome
The sequence of the human genome encodes the genetic instructions for human physiology, as well as rich information about human evolution. In 2001, the International Human Genome Sequencing Consortium reported a draft sequence of the euchromatic portion of the human genome. Since then, the international collaboration has worked to convert this draft into a genome sequence with high accuracy and nearly complete coverage. Here, we report the result of this finishing process. The current genome sequence (Build 35) contains 2.85 billion nucleotides interrupted by only 341 gaps. It covers âŒ99% of the euchromatic genome and is accurate to an error rate of âŒ1 event per 100,000 bases. Many of the remaining euchromatic gaps are associated with segmental duplications and will require focused work with new methods. The near-complete sequence, the first for a vertebrate, greatly improves the precision of biological analyses of the human genome including studies of gene number, birth and death. Notably, the human enome seems to encode only 20,000-25,000 protein-coding genes. The genome sequence reported here should serve as a firm foundation for biomedical research in the decades ahead

Brain multiplexes reveal morphological connectional biomarkers fingerprinting late brain dementia states
Accurate diagnosis of mild cognitive impairment (MCI) before conversion to Alzheimerâs disease (AD) is invaluable for patient treatment. Many works showed that MCI and AD affect functional and structural connections between brain regions as well as the shape of cortical regions. However, âshape connectionsâ between brain regions are rarely investigated -e.g., how morphological attributes such as cortical thickness and sulcal depth of a specific brain region change in relation to morphological attributes in other regions. To fill this gap, we unprecedentedly design morphological brain multiplexes for late MCI/AD classification. Specifically, we use structural T1-w MRI to define morphological brain networks, each quantifying similarity in morphology between different cortical regions for a specific cortical attribute. Then, we define a brain multiplex where each intra-layer represents the morphological connectivity network of a specific cortical attribute, and each inter-layer encodes the similarity between two consecutive intra-layers. A significant performance gain is achieved when using the multiplex architecture in comparison to other conventional network analysis architectures. We also leverage this architecture to discover morphological connectional biomarkers fingerprinting the difference between late MCI and AD stages, which included the right entorhinal cortex and right caudal middle frontal gyrus

Multimodal and Multiscale Deep Neural Networks for the Early Diagnosis of Alzheimerâs Disease using structural MR and FDG-PET images
Alzheimerâs Disease (AD) is a progressive neurodegenerative disease where biomarkers for disease based on pathophysiology may be able to provide objective measures for disease diagnosis and staging. Neuroimaging scans acquired from MRI and metabolism images obtained by FDG-PET provide in-vivo measurements of structure and function (glucose metabolism) in a living brain. It is hypothesized that combining multiple different image modalities providing complementary information could help improve early diagnosis of AD. In this paper, we propose a novel deep-learning-based framework to discriminate individuals with AD utilizing a multimodal and multiscale deep neural network. Our method delivers 82.4% accuracy in identifying the individuals with mild cognitive impairment (MCI) who will convert to AD at 3 years prior to conversion (86.4% combined accuracy for conversion within 1â3 years), a 94.23% sensitivity in classifying individuals with clinical diagnosis of probable AD, and a 86.3% specificity in classifying non-demented controls improving upon results in published literature
