    Critical Moments of Meaning and Being: Narratives of Cancer during Young Adult Life

    Emerging conversations within oncology have drawn more attention to cancer among young adults (ages 18-45). Recent research has illuminated many of the psychosocial difficulties young adults face as they go through the many trials and tribulations of chronic illness. However, a subject still understudied, much is unclear about the personal as well as the cultural implications of being diagnosed during this period of time. In a book of cancer stories, performer and young adult cancer patient Kairol Rosenthal (2009) expressed her frustration with what she saw as “stereotypes” promulgated by the limited public discourses that exist on the subject (p. 7). She sought to counterbalance these representations with stories capturing the “complexities of our real daily lives” (p. 7). Indeed, in oncological discourses young adults tend to be cast in oversimplified terms, based upon cultural expectations about what young adulthood should be and pressures to conform to those standards. Intersecting with dominant discourses within narrative identity development, two imperatives are placed upon young adults’ stories: integration of different life experiences and selves into a coherent narrative and developing a sense of self-authorship in the direction of one’s life. What seems to be lost in these imperatives within the existing research is what is at stake for individual lives (a phenomenological perspective) and how those stakes are negotiated or contested with hegemonic trajectories of life (a critical perspective). Receptive to Rosenthal’s critique of dominant discourses around cancer and young adulthood, the purpose of this thesis was to explore the complexity and diversity of young adults living with cancer. More specifically, I intended to interrogate some of their existential and biographical challenges as expressed in their narratives of cancer, as well as their engagements with ideological constructions of young adulthood, namely, the expectations of narrative coherence and self-authorship. This research marked a departure from most studies on the subject in its qualitative methodology (i.e., narrative analysis) and in its explicit evaluation of the effects of cultural discourses on young adults’ attempts to make meaning. More generally, this research shows the importance of language—in discourses, narratives, and metaphors—in constructing and communicating illness experiences. For this project, I gathered a mix of written and oral narratives (through semi-structured interviews) from 21 participants from across Canada. The foci of analyses were on what could be called narrative ‘moments of meaning’ and ‘moments of being,’ that is, situated expressions of how they made sense of their worlds and themselves. Many of these were critical moments in the sense of questioning and resisting dominant discourses of cancer and young adulthood. Their moments of meaning often expressed negotiation of personal desires and innovative intentions with familiar cultural narratives or “prototypical plots” (Good, 1994)—including stories of battling cancer, embarking on a life journey, nearing recovery, encountering unpredictability and mystery, and living with chaos. These moments of meaning served an array of purposes well beyond the expected function of constructing a coherent narrative. When telling of identity disruptions and the liminality of cancer, participants produced both more orderly moments of being (e.g., survivor, patient, or warrior identities) and more liminal moments of non-being (e.g., victim, phoenix, or trickster identities). Self-authorship seemed to be present among the former, while the latter expressed less control and certainty of being—which was not always seen as a problem. These moments of being and non-being were collaborated and contested within the intersubjective spaces of their clinical relationships, local worlds, and cancer patient communities. More specific to their age group, their moments of being and non-being often related to what may be understood as developmental identities, including the ‘traditional milestones’ such as individual autonomy, family (i.e., marriage and parenthood), and vocation (i.e., getting an education and building a career). In their struggles they sometimes reaffirmed these cultural ideals toward identity integration and other times resisted them as “normalizing ideologies” (Becker, 1997) of young adulthood. As part of these larger negotiations of meaning and being, the participants expressed struggles to understand the moral significance of their illnesses. Confronted with what may be called “causal ontologies” of suffering (Shweder, 1997), they spoke of different etiological models of cancer’s origins as well as reconciliatory models for living with cancer in the future. Their narratives sometimes led toward “remoralization” (Kleinman, 1988)—couching experiences of suffering in terms of a moral order (narrative coherence) and personal responsibility (self-authorship)—and sometimes led away from it, depending on whether they believed their illnesses originated from events in their personal and social lives. Overall, the participants in this study communicated complex and potentially chronic existential challenges. In many ways their narratives resisted dominant representations of young adults with cancer—and of cancer patients in general—suggesting that such representations need to be rethought. Their critical moments of meaning and being may serve as counternarratives to the stereotypes of concern to Rosenthal and many other cancer patients. Specifically, their narratives revealed the merits and limits of the ideological construction of young adulthood as a time of narrative coherence and self-authorship. This study has important implications for future health research and psychosocial support in the field of oncology; building upon a “narrative medicine” (Charon, 2006), sensitivity to how language is used among young adult cancer patients may lead toward more inclusive clinical practices

    The purpose of this paper is to validate the impact attenuator designed by SDSU Formula SAE team according to 2010 Formula SAE rules. The impact attenuator is made of Plascore PCGA-XR1-5.2-1/4-P-3003 aluminum honeycomb that is pre-crushed to 245 psi. The test was dynamically performed using a 661 lb mass dropped 8.3 ft onto the material sample at 23 ft/sec, and data was measured with an Olympus i-SPEED 3 high speed camera. The impact attenuator must have an average deceleration equal to or less than 20 G’s and a peak deceleration equal to or less than 40 G’s. Two specimens were tested. The physical dimensions of the first specimen are 10 inches long by 8 inches wide by 5 inches tall. Data of the first sample showed a peak deceleration of 46.88 G’s and an average deceleration of 17.86 G’s. The velocity at impact was above 24ft/sec. The second specimen is 10 inches long by 10 inches wide by 4 inches tall. The second sample had a peak deceleration of 36.2 G’s and an average deceleration of 14 G’s. The velocity at impact was slightly above 23ft/sec. The first sample was unacceptable and the second specimen was acceptable under the guidelines set forth by Formula SAE Rule B.3.21.1

    Deliberative democracy and inequality: Two cheers for enclave deliberation among the disempowered

    Get PDF
    Deliberative democracy grounds its legitimacy largely in the ability of speakers to participate on equal terms. Yet theorists and practitioners have struggled with how to establish deliberative equality in the face of stark differences of power in liberal democracies. Designers of innovative civic forums for deliberation often aim to neutralize inequities among participants through proportional inclusion of disempowered speakers and discourses. In contrast, others argue that democratic equality is best achieved when disempowered groups deliberate in their own enclaves (interest groups, parties, and movements) before entering the broader public sphere. Borrowing from each perspective, the authors argue that there are strong reasons to incorporate enclave deliberation among the disempowered within civic forums. They support this claim by presenting case study evidence showing that participants in such forums can gain some of the same benefits of deliberation found in more heterogeneous groups (e.g., political knowledge, efficacy and trust), can consider a diversity of viewpoints rather than falling into groupthink and polarization, and can persuade external stakeholders of the legitimacy of the group’s deliberations

    Ligation of OX40 (CD134, TNFRSF4) on activated T cells by its natural ligand (OX40L, CD252, TNFSF4) enhances cellular survival, proliferation, and effector functions such as cytokine release and cellular cytotoxicity. We engineered a recombinant human OX40L IgG4P Fc fusion protein termed MEDI6383 that assembles into a hexameric structure and exerts potent agonist activity following engagement of OX40. MEDI6383 displayed solution-phase agonist activity that was enhanced when the fusion protein was clustered by Fc gamma receptors (FcγRs) on the surface of adjacent cells. The resulting costimulation of OX40 on T cells induced NFκB promoter activity in OX40-expressing T cells and induced Th1-type cytokine production, proliferation, and resistance to regulatory T cell (Treg)-mediated suppression. MEDI6383 enhanced the cytolytic activity of tumor-reactive T cells and reduced tumor growth in the context of an alloreactive human T cell:tumor cell admix model in immunocompromised mice. Consistent with the role of OX40 costimulation in the expansion of memory T cells, MEDI6383 administered to healthy nonhuman primates elicited peripheral blood CD4 and CD8 central and effector memory T-cell proliferation as well as B-cell proliferation. Together, these results suggest that OX40 agonism has the potential to enhance antitumor immunity in human malignancies

    High frequency of known copy number abnormalities and maternal duplication 15q11-q13 in patients with combined schizophrenia and epilepsy

    <p>Abstract</p> <p>Background</p> <p>Many copy number variants (CNVs) are documented to be associated with neuropsychiatric disorders, including intellectual disability, autism, epilepsy, schizophrenia, and bipolar disorder. Chromosomal deletions of 1q21.1, 3q29, 15q13.3, 22q11.2, and <it>NRXN1 </it>and duplications of 15q11-q13 (maternal), 16p11, and 16p13.3 have the strongest association with schizophrenia. We hypothesized that cases with both schizophrenia and epilepsy would have a higher frequency of disease-associated CNVs and would represent an enriched sample for detection of other mutations associated with schizophrenia.</p> <p>Methods</p> <p>We used array comparative genomic hybridization (CGH) to analyze 235 individuals with both schizophrenia and epilepsy, 80 with bipolar disorder and epilepsy, and 191 controls.</p> <p>Results</p> <p>We detected 10 schizophrenia plus epilepsy cases in 235 (4.3%) with the above mentioned CNVs compared to 0 in 191 controls (p = 0.003). Other likely pathological findings in schizophrenia plus epilepsy cases included 1 deletion 16p13 and 1 duplication 7q11.23 for a total of 12/235 (5.1%) while a possibly pathogenic duplication of 22q11.2 was found in one control for a total of 1 in 191 (0.5%) controls (p = 0.008). The rate of abnormality in the schizophrenia plus epilepsy of 10/235 for the more definite CNVs compares to a rate of 75/7336 for these same CNVs in a series of unselected schizophrenia cases (p = 0.0004).</p> <p>Conclusion</p> <p>We found a statistically significant increase in the frequency of CNVs known or likely to be associated with schizophrenia in individuals with both schizophrenia and epilepsy compared to controls. We found an overall 5.1% detection rate of likely pathological findings which is the highest frequency of such findings in a series of schizophrenia patients to date. This evidence suggests that the frequency of disease-associated CNVs in patients with both schizophrenia and epilepsy is significantly higher than for unselected schizophrenia.</p

    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 ∼99% of the euchromatic genome and is accurate to an error rate of ∼1 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

    Guidelines for the use and interpretation of assays for monitoring autophagy (3rd edition)

    Get PDF
    In 2008 we published the first set of guidelines for standardizing research in autophagy. Since then, research on this topic has continued to accelerate, and many new scientists have entered the field. Our knowledge base and relevant new technologies have also been expanding. Accordingly, it is important to update these guidelines for monitoring autophagy in different organisms. Various reviews have described the range of assays that have been used for this purpose. Nevertheless, there continues to be confusion regarding acceptable methods to measure autophagy, especially in multicellular eukaryotes. For example, a key point that needs to be emphasized is that there is a difference between measurements that monitor the numbers or volume of autophagic elements (e.g., autophagosomes or autolysosomes) at any stage of the autophagic process versus those that measure fl ux through the autophagy pathway (i.e., the complete process including the amount and rate of cargo sequestered and degraded). In particular, a block in macroautophagy that results in autophagosome accumulation must be differentiated from stimuli that increase autophagic activity, defi ned as increased autophagy induction coupled with increased delivery to, and degradation within, lysosomes (inmost higher eukaryotes and some protists such as Dictyostelium ) or the vacuole (in plants and fungi). In other words, it is especially important that investigators new to the fi eld understand that the appearance of more autophagosomes does not necessarily equate with more autophagy. In fact, in many cases, autophagosomes accumulate because of a block in trafficking to lysosomes without a concomitant change in autophagosome biogenesis, whereas an increase in autolysosomes may reflect a reduction in degradative activity. It is worth emphasizing here that lysosomal digestion is a stage of autophagy and evaluating its competence is a crucial part of the evaluation of autophagic flux, or complete autophagy. Here, we present a set of guidelines for the selection and interpretation of methods for use by investigators who aim to examine macroautophagy and related processes, as well as for reviewers who need to provide realistic and reasonable critiques of papers that are focused on these processes. These guidelines are not meant to be a formulaic set of rules, because the appropriate assays depend in part on the question being asked and the system being used. In addition, we emphasize that no individual assay is guaranteed to be the most appropriate one in every situation, and we strongly recommend the use of multiple assays to monitor autophagy. Along these lines, because of the potential for pleiotropic effects due to blocking autophagy through genetic manipulation it is imperative to delete or knock down more than one autophagy-related gene. In addition, some individual Atg proteins, or groups of proteins, are involved in other cellular pathways so not all Atg proteins can be used as a specific marker for an autophagic process. In these guidelines, we consider these various methods of assessing autophagy and what information can, or cannot, be obtained from them. Finally, by discussing the merits and limits of particular autophagy assays, we hope to encourage technical innovation in the field
