Voldemort Tyrannos: Plato’s Tyrant in the Republic and the Wizarding World
In the Harry Potter novel series, by J. K. Rowling, the character of Lord Voldemort is the dictatorial ruler of the Death Eaters and aspiring despot of the entire wizarding community. As such, he serves as an apt subject for the application of Plato’s portrait of the tyrant in Republic IX. The process of applying Plato to Voldemort, however, leads to an apparent anomaly, the resolution of which requires that we move beyond the Republic to the account of beauty presented by Plato in the Symposium. In doing so, we shall find that while Plato can help us to understand Voldemort, Voldemort can also help us to attain a deeper understanding of Plato
Pragmatism and Meaning: Assessing the Message of Star Trek: The Original Series
The original Star Trek television series purported to depict a future in which such evils as sexism and racism do not exist, and intelligent beings from numerous planets live in a condition of peace and mutual benefit. As many scholars have observed, from a standpoint of contemporary theoretical analysis, Star Trek: The Original Series contains many elements that are inimical to the utopia it claims to depict and thus undermine its supposed message. A different perspective may be gained by drawing on the American pragmatist movement, in which the value of an idea is judged by its effectiveness, how it ‘cashes out’ in terms of its impact in real life. Thus, the meaning and value of Star Trek: TOS can be assessed by observing its effects on its audience. This perspective coordinates well with Taylor’s discussion of the necessary conditions for the realization of a protreptic moral order in the social imaginary, as well as a pragmatist understanding of audience engagement and education
A Prison for Others—A Burden to One\u27s Self
Women have come a long way since the mid-1960\u27s, both in the real world and in the world of philosophy. Given the advances in society and the developments within feminism that took place between that decade and the first decade of the 21st century, we might reasonably expect the new Prisonerseries to present a more contemporary perspective on women than the original. Such is most emphatically not the case. If we compare the original Village to the new one, it looks as if those pennyfarthing wheels are spinning backwards instead of forwards
Bare Below the Elbows: A comparative study of a tertiary and district general hospital.
A \u27Bare Below the Elbows\u27 (BBTE) dress code policy has been introduced by the majority of NHS trusts in the UK. The aim of this Irish study was to evaluate the impact of an educational intervention on perception of medical attire. The study was carried out in two centres: a tertiary referral centre (Beaumont Hospital) and a district hospital (MRH, Portlaoise). Two questionnaires, incorporating photographic evaluation of appropriate attire for consultants and junior doctors, were completed pre and post BBTE education. One hundred and five patients participated. Analysis pre BBTE education indicated patients considered formal attire and white coats most appropriate for consultants and junior doctors respectively. Post-intervention analysis revealed a significant reduction in the popularity of both (

Women\u27s preferences for selective estrogen reuptake modulators: an investigation using the time trade off technique
PurposeSelective Estrogen Receptor Modulators (SERMs) reduce the risk of breast cancer for women at increased risk by 38%. However, uptake is extremely low and the reasons for this are not completely understood. The aims of this study were to utilize time trade-off methods to determine the degree of risk reduction required to make taking SERMs worthwhile to women, and the factors associated with requiring greater risk reduction to take SERMs. MethodsWomen at increased risk of breast cancer (N = 107) were recruited from two familial cancer clinics in Australia. Participants completed a questionnaire either online or in pen and paper format. Hierarchical multiple linear regression analysis was used to analyze the data. ResultsOverall, there was considerable heterogeneity in the degree of risk reduction required to make taking SERMs worthwhile. Women with higher perceived breast cancer risk and those with stronger intentions to undergo (or who had undergone) an oophorectomy required a smaller degree of risk reduction to consider taking SERMs worthwhile. ConclusionWomen at increased familial risk appear motivated to consider SERMs for prevention. A tailored approach to communicating about medical prevention is essential. Health professionals could usefully highlight the absolute (rather than relative) probability of side effects and take into account an individual’s perceived (rather than objective) risk of breast cancer
Inhibition of the glucocorticoid receptor results in an enhanced miR-99a/100-mediated radiation response in stem-like cells from human prostate cancers
Radiation therapy is a major primary treatment option for both localized early stage prostate cancer, and for advanced, regionally un-resectable, cancer. However, around 30% of patients still experience biochemical recurrence after radiation therapy within 10 years. Thus, identification of better biomarkers and new targets are urgently required to improve current therapeutic strategies. The miR-99 family has been shown to play an important role in the regulation of the DNA damage response, via targeting of the SWI/SNF chromatin remodeling factors, SMARCA5 and SMARCD1 in cell line models. In the present study, we have demonstrated that low expression of miR-99a and miR-100 is present in cell populations which are relatively radiation insensitive, for example in prostate cancer stem cells and in castration-resistant prostate cancer. Additionally, treatment of cells with the synthetic glucocorticoid, Dexamethasone resulted in decreased miR-99a and 100 expression, suggesting a new mechanism of miR-99a and 100 regulation in androgen-independent prostate cells. Strikingly, treatment of prostate cells with the glucocorticoid receptor inhibitor, Mifepristone was found to sensitize prostate cells to radiation by increasing the levels of miR-99a and miR-100. These results qualify the miR99 family as markers of radiation sensitivity and as potential therapeutic targets to improve efficiency of radiotherapy
Inhibition of the PI3K/AKT/mTOR pathway activates autophagy and compensatory Ras/Raf/MEK/ERK signalling in prostate cancer
The PI3K/AKT/mTOR pathway is frequently activated in advanced prostate cancer, due to loss of the tumour suppressor PTEN, and is an important axis for drug development. We have assessed the molecular and functional consequences of pathway blockade by inhibiting AKT and mTOR kinases either in combination or as individual drug treatments. In established prostate cancer cell lines, a decrease in cell viability and in phospho-biomarker expression was observed. Although apoptosis was not induced, a G1 growth arrest was observed in PTEN null LNCaP cells, but not in BPH1 or PC3 cells. In contrast, when the AKT inhibitor AZD7328 was applied to patient-derived prostate cultures that retained expression of PTEN, activation of a compensatory Ras/MEK/ERK pathway was observed. Moreover, whilst autophagy was induced following treatment with AZD7328, cell viability was less affected in the patient-derived cultures than in cell lines. Surprisingly, treatment with a combination of both AZD7328 and two separate MEK1/2 inhibitors further enhanced phosphorylation of ERK1/2 in primary prostate cultures. However, it also induced irreversible growth arrest and senescence.Ex vivo treatment of a patient-derived xenograft (PDX) of prostate cancer with a combination of AZD7328 and the mTOR inhibitor KU-0063794, significantly reduced tumour frequency upon re-engraftment of tumour cells.The results demonstrate that single agent targeting of the PI3K/AKT/mTOR pathway triggers activation of the Ras/MEK/ERK compensatory pathway in near-patient samples. Therefore, blockade of one pathway is insufficient to treat prostate cancer in man
