An Apocalypse of Change: The Reconstruction of the American Identity in Post-9/11 Cinema

Thesis advisor: Bonnie JeffersonThis paper analyzes the reconstruction of the American identity through the lens of two post-modern films: Paul Haggis’ Crash and Tony Kushner’s Angels in America. First, the role of 9/11 on the resurgence of trauma culture and its catalytic effect on the start of the post-modern era is examined. This analysis argues that these films unite American citizens through the central notion of humanity that mankind ultimately shares. This is achieved through the framework of three central themes: the elimination of the typified other, the restoration of faith in mankind and the human condition, and the uniting sense of touch. The construction of these themes reconciles the ambiguity and uncertainty inherent in all aspects of the post-modern era. These films serve as metaphorical narrative vehicles and function to draw the American people back into a sense of a universal, national identity in the wake of September 11. In addition, they foster reassurance in the American spirit and ensure the ability of the United States to initiate collective recovery after periods of intense national trauma.Thesis (BA) — Boston College, 2010.Submitted to: Boston College.

The mPower Study, Parkinson Disease Mobile Data Collected Using Researchkit

Current measures of health and disease are often insensitive, episodic, and subjective. Further, these measures generally are not designed to provide meaningful feedback to individuals. The impact of high-resolution activity data collected from mobile phones is only beginning to be explored. Here we present data from mPower, a clinical observational study about Parkinson disease conducted purely through an iPhone app interface. The study interrogated aspects of this movement disorder through surveys and frequent sensor-based recordings from participants with and without Parkinson disease. Benefitting from large enrollment and repeated measurements on many individuals, these data may help establish baseline variability of real-world activity measurement collected via mobile phones, and ultimately may lead to quantification of the ebbs-and-flows of Parkinson symptoms. App source code for these data collection modules are available through an open source license for use in studies of other conditions. We hope that releasing data contributed by engaged research participants will seed a new community of analysts working collaboratively on understanding mobile health data to advance human health

Dietary intake of micronutrients and the risk of developing bladder cancer: results from the Belgian case–control study on bladder cancer risk

OBJECTIVE: We aimed to investigate the effect of dietary intake of micronutrients that are metabolized and excreted via the urinary tract on bladder cancer risk. METHODS: A semi-quantitative 322 item food frequency questionnaire (FFQ) was used to collect dietary data from 200 bladder cancer cases and 386 control subjects participating in the Belgian case-control study on bladder cancer risk. Odds ratios (ORs) and 95% confidence intervals (CIs) were calculated using unconditional logistic regression adjusting for age, sex, smoking characteristics, occupational exposures, and energy intake. RESULTS: We observed a positive association between calcium intake and bladder cancer (OR: 1.77; 95% CI: 1.00-3.15; p-trend = 0.049) and increased odds, although not statistically significant, for highest tertile of phosphorus intake (OR: 1.82; 95% CI: 0.95-3.49; p-trend = 0.06). We identified possible modification of the effects of both calcium and phosphorus by level of magnesium intake. Increased odds of bladder cancer were also observed for participants with highest intake of phosphorus and lowest intake of vitamin D (OR: 4.25; 95% CI: 1.44-12.55) and among older participants with the highest intakes of calcium (OR: 1.90; 95% CI: 1.08-3.36) and phosphorus (OR: 2.02; 95% CI: 1.05-3.92). CONCLUSION: The positive associations we observed between bladder cancer and intake of calcium and phosphorus require confirmation by other studies. The balances between inter-related micronutrients also warrant further examination

Elevated tph2 mRNA expression in a rat model of chronic anxiety

BACKGROUND: Allelic variations in TPH2, the gene encoding tryptophan hydroxylase 2, the rate-limiting enzyme for brain serotonin (5-HT) biosynthesis, may be genetic predictors of panic disorder and panic responses to panicogenic challenges in healthy volunteers. To test the hypothesis that tph2 mRNA is altered in chronic anxiety states, we measured tph2 expression in an established rat model of panic disorder. METHODS: We implanted 16 adult, male rats with bilateral guide cannulae and then primed them with daily injections of the corticotropin-releasing factor (CRF) receptor agonist, urocortin 1 (UCN1, 6 fmoles/100 nl per side, n = 8) or vehicle (n = 8) into the basolateral amygdaloid complex (BL) for 5 consecutive days. Anxiety-like behavior was assessed, 24 hr prior to and 48 hr following priming, in the social interaction (SI) test. A third group (n = 7) served as undisturbed home cage controls. All rats were killed 3 days after the last intra-BL injection to analyze tph2 and slc6a4 (gene encoding the serotonin transporter, SERT) mRNA expression in the dorsal raphe nucleus (DR), the main source of serotonergic projections to anxiety-related brain regions, using in situ hybridization histochemistry. RESULTS: UCN1 priming increased anxiety-related behavior in the SI test compared to vehicle-injected controls and elevated tph2, but not slc6a4, mRNA expression in DR subregions, including the ventrolateral DR/ventrolateral periaqueductal gray (DRVL/VLPAG), a subregion previously implicated in control of panic-related physiologic responses. Tph2 mRNA expression in the DRVL/VLPAG was correlated with increased anxiety-related behavior. CONCLUSION: Our data support the hypothesis that chronic anxiety states are associated with dysregulated tph2 expression

A Gene Expression Fingerprint of C. Elegans Embryonic Motor Neurons

Differential gene expression specifies the highly diverse cell types that constitute the nervous system. With its sequenced genome and simple, well-defined neuroanatomy, the nematode C. elegans is a useful model system in which to correlate gene expression with neuron identity. The UNC-4 transcription factor is expressed in thirteen embryonic motor neurons where it specifies axonal morphology and synaptic function. These cells can be marked with an unc-4::GFP reporter transgene. Here we describe a powerful strategy, Micro-Array Profiling of C. elegans cells (MAPCeL), and confirm that this approach provides a comprehensive gene expression profile of unc-4::GFP motor neurons in vivo.

Metodologia para definição de unidades territoriais de planejamento do transporte interurbano de pessoas no Brasil

No Brasil, é comum o desenvolvimento de planos e estudos voltados à mobilidade urbana, mas a mobilidade interurbana, em escala nacional, não é estudada como um sistema integrado, grande parte em razão da segregação institucional de gestão e planejamento de sistemas de transporte, o que dificulta a visão do território , a compreensão do contexto geográfico e limita o desenvolvimento técnico do planejamento sob uma visão sistêmica. Portanto, a fim de materializar um zoneamento que permita a definição de um contexto geográfico de referência, esse artigo propõe uma metodologia para definição de Unidades Territoriais de Planejamento – UTP, aqui definidas como as regiões onde se concentram as populações e agrupam os fluxos intraurbanos. Para tanto, foram utilizados como base de dados informações sobre o transporte terrestre rodoviário e ferroviário, aeroviário, aquaviário, além de Planos Nacionais de Turismo (MTur, 2013), de Logística (EPL, 2018), Plano Aeroviário Nacional (MTPA, 2018) e estudos do IBGE (2008, 2016, 2017a, 2017b). Conclui- se que, apesar de ser um recorte inicial, com as UTPs definidas para o planejamento do transporte interurbano de pessoas no Brasil, é possível iniciar uma análise sistêmica, e consequentemente, evoluir o planejamento das infraestruturas e serviços envolvidos.

Granulysin-Expressing CD4+ T Cells as Candidate Immune Marker for Tuberculosis during Childhood and Adolescence

BACKGROUND: Granulysin produced by cytolytic T cells directly contributes to immune defense against tuberculosis (TB). We investigated granulysin as a candidate immune marker for childhood and adolescent TB. METHODS: Peripheral blood mononuclear cells (PBMC) from children and adolescents (1-17 years) with active TB, latent TB infection (LTBI), nontuberculous mycobacteria (NTM) infection and from uninfected controls were isolated and restimulated in a 7-day restimulation assay. Intracellular staining was then performed to analyze antigen-specific induction of activation markers and cytotoxic proteins, notably, granulysin in CD4(+) CD45RO(+) memory T cells. RESULTS: CD4(+) CD45RO(+) T cells co-expressing granulysin with specificity for Mycobacterium tuberculosis (Mtb) were present in high frequency in TB-experienced children and adolescents. Proliferating memory T cells (CFSE(low)CD4(+)CD45RO(+)) were identified as main source of granulysin and these cells expressed both central and effector memory phenotype. PBMC from study participants after TB drug therapy revealed that granulysin-expressing CD4(+) T cells are long-lived, and express several activation and cytotoxicity markers with a proportion of cells being interferon-gamma-positive. In addition, granulysin-expressing T cell lines showed cytolytic activity against Mtb-infected target cells. CONCLUSIONS: Our data suggest granulysin expression by CD4(+) memory T cells as candidate immune marker for TB infection, notably, in childhood and adolescence

Epidemiology of Chronic Pain in Denmark and Sweden

Introduction. Estimates on the epidemiology of chronic pain vary widely throughout Europe. It is unclear whether this variation reflects true differences between populations or methodological factors. Information on the epidemiology of chronic pain can support decision makers in allocating adequate health care resources. Methods. In order to obtain epidemiological data on chronic pain in Denmark and Sweden, we conducted a literature review of epidemiological data primarily on chronic noncancer pain, prioritising studies of highest quality, recency, and validity by conducting a systematic search for relevant studies. Following quality assessment, data were summarised and assigned to the research questions. Results. The prevalence of moderate to severe noncancer pain was estimated at 16% in Denmark and 18% in Sweden. Chronic pain impacts negatively on perceived health status, quality of life and is associated with increased cost. Despite using pain medications, a large proportion of chronic pain sufferers have inadequate pain control. There was a lack of high-quality and low-bias studies with clear inclusion criteria. Conclusions. In both Denmark and Sweden, chronic pain is a common health problem which is potentially undertreated and warrants attention of health care workers, policy makers and researchers. Future research should utilise clear reporting guidelines to assist decision and policy makers, in this important area
