Displaced Stories: The Interplay of Telling and Being in the Face of Displacement

Throughout the last decades, narrative approaches have become quintessential tools for understanding crisis and displacement. While a focus on individual stories allows for a deep look into the particularity of being-displaced, it simultaneously runs the risk of romanticising the outcome (the life story) of what is indeed the product of a rather complex process (the telling of the life story). In this paper I will discuss a change of perspectives: Rather than laying the focus on life stories as texts, I will suggest to shift the attention towards the existential dynamics of storytelling. By zooming in on my longstanding collaboration with a Somali woman in Melbourne, Australia, I will map out the interplay of telling and being that marked this process. Focusing on one particular storytelling moment, I will suggest the importance of appreciating the intersubjective force of storytelling. Rather than melting the set of stories into a coherent “life story”, I will look at the storytelling moment in its lived messiness. In doing so, I will sketch out its potential to shed light both on the teller’s hopes, imaginations and ambitions, and on the reality of being part of a wider world that often contradicts and shatters these hopes.

Pelvic floor muscle displacement during voluntary and involuntary activation in continent and incontinent women: a systematic review.

INTRODUCTION Investigations of the dynamic function of female pelvic floor muscles (PFM) help us to understand the pathophysiology of stress urinary incontinence (SUI). Displacement measurements of PFM give insight into muscle activation and thus help to improve rehabilitation strategies. This systematic review (PROSPERO 2013: CRD42013006409) was performed to summarise the current evidence for PFM displacement during voluntary and involuntary activation in continent and incontinent women. METHODS MEDLINE, EMBASE, Cochrane and SPORTDiscus databases were searched using selected terminology reflecting the PICO approach. Screening of Google Scholar and congress abstracts added to further information. Original articles investigating PFM displacement were included if they reported on at least one of the aims of the review, e.g., method, test position, test activity, direction and quantification of displacement, as well as the comparison between continent and incontinent women. Titles and abstracts were screened by two reviewers. The papers included were reviewed by two individuals to ascertain whether they fulfilled the inclusion criteria and data were extracted on outcome parameters. RESULTS Forty-two predominantly observational studies fulfilled the inclusion criteria. A variety of measurement methods and calculations of displacement was presented. The sample was heterogeneous concerning age, parity and continence status. Test positions and test activities varied among the studies. CONCLUSIONS The findings summarise the present knowledge of PFM displacement, but still lack deeper comprehension of the SUI pathomechanism of involuntary, reflexive activation during functional activities. We therefore propose that future investigations focus on PFM dynamics during fast and stressful impact tasks.

ANALYSIS OF ESTROGEN-INDUCED ANEUPLOIDY AND CHROMOSOME DISPLACEMENT

Diethylstilbestrol (DES) is a known human carcinogen and teratogen whose mechanism of action remains undetermined. As essentially diploid Chinese hamster cell line (Don) was used to test diethylstilbestrol (DES), dienestrol, hexestrol and the naturally occurring estrogens, estradiol and estriol for their ability to cause metaphase arrest and to induce aneuploidy. These compounds arrest mitosis within a narrow range of high concentrations and induce aneuploidy in recovering cell populations. DES was the most effective arrestant on a comparative molar basis. Estradiol and estriol were less potent as arrestants but were effective inducers of aneuploidy. Aneuploidy was induced in a non-random manner. The smallest chromosomes were most frequently recorded in aneuploid cells. Using anti-tubulin antibody and indirect immunofluorescence, it was found that DES inhibits bi-polar spindle assembly and disrupts the cytoplasmic microtubule complex (CMTC). Estradiol arrests mitosis in a manner that allows spindle assembly. Estradiol has no apparent effect on the CMTC. The naturally occurring estrogens caused chromosome displacement during mitotic arrest. Electron microscopy confirmed that the displaced chromosomes appeared at the polar regions of arrested cells. The arresting effect of estradiol, and to some extent DES, was reduced by the addition of dibutyryl cyclic adenosine monophosphate (db-cAMP). Aneuploidy induction by DES and similar compounds may be related to their carcinogenic and/or teratogenic potential. ^
