    PhDThe question 'Where does she begin and I end, asked in Virginia Woolf's The Years, voices a modernist concern with the limits of self-identity and related questions of egoism and altruism. In this thesis I argue that this concern is informed by a pre-history of thinking about selfhood, psychic boundaries and the spiritual mainly ignored by readings of modernism which map the psyche via psychoanalysis, or Freud's 'discovery of the unconscious'. Our thinking about the self has become colonised by the literary doctrines of better known canonical figures of the modernist period, generating a way of thinking about the limits of the psyche which is both literally and metaphorically circumscribed. A reading of more eccentric discourses explicitly engaged in negotiating the boundaries of individuality can provide a history of the psychic underpinnings to the modernist conception of the self. The representation of marginal states of consciousness, or epiphanic moments, is crucial to the literature of modernism: interpretation of these altered states, or edges, can be refigured through readings of Vernon Lee, Evelyn Underhill, May Sinclair, Dion Fortune and Jane Harrison: five women writing between 1880-1930 for whom pre-Freudian forms of dissolution and challenge to self-unity are palpably present in the form of telepathy, subliminal selves, oceanic consciousness and internal multiplicity. In addition to writing non-fictional texts which variously explore the psychological, philosophical, ethical, spiritual and occult implications of the modernist position, each of these women, excepting the classical scholar Jane Harrison, also wrote fiction. The aesthetic questions of modernism dovetail into the theoretical arguments of the writers in this thesis, inviting a different reading of its psychological sub-text and to suggest that where 'stream-of-consciousness' is stylistically indispensable, the 'oceanic', as counterpart, thematically haunts the modernist aestheti

    EZH2 modifies sunitinib resistance in renal cell carcinoma by kinome reprogramming

    Acquired and intrinsic resistance to receptor tyrosine kinase inhibitors (RTKi) represent a major hurdle in improving the management of clear cell renal cell carcinoma (ccRCC). Recent reports suggest that drug resistance is driven by tumor adaptation via epigenetic mechanisms that activate alternative survival pathways. The histone methyl transferase EZH2 is frequently altered in many cancers including ccRCC. To evaluate its role in ccRCC resistance to RTKi, we established and characterized a spontaneously metastatic, patient-derived xenograft (PDX) model that is intrinsically resistant to the RTKI sunitinib but not to the VEGF therapeutic antibody bevacizumab. Sunitinib maintained its anti-angiogenic and anti-metastatic activity but lost its direct anti-tumor effects due to kinome reprogramming, which resulted in suppression of pro- apoptotic and cell cycle regulatory target genes. Modulating EZH2 expression or activity suppressed phosphorylation of certain RTK, restoring the anti-tumor effects of sunitnib in models of acquired or intrinsically resistant ccRCC. Overall, our results highlight EZH2 as a rational target for therapeutic intervention in sunitinib-resistant ccRCC as well as a predictive marker for RTKi response in this disease.This research was funded by Roswell Park Cancer Institute’s Cancer Center Support Grant from National Cancer Institute, NIH P30CA016056 (RP) and a generous donation by Richard and Deidre Turner (RP).

    Finishing the euchromatic sequence of the human genome

    Get PDF
    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

    Proton–proton collision data recorded in 2011 and 2012 by the LHCb experiment, corresponding to an integrated luminosity of 3.0 fb−1 , are analysed to search for the charmless B0→ρ0ρ0 decay. More than 600 B0→(π+π−)(π+π−) signal decays are selected and used to perform an amplitude analysis, under the assumption of no CP violation in the decay, from which the B0→ρ0ρ0 decay is observed for the first time with 7.1 standard deviations significance.

The production cross-sections of D0D^0, D+D^+, Ds+D_s^+, and D+D^{*+} mesons are measured in bins of charm meson transverse momentum, pTp_{\text{T}}, and rapidity, yy. They cover the rapidity range 2.0<y<4.52.0 < y < 4.5 and transverse momentum ranges 0<pT<10GeV/c0 < p_{\text{T}} < 10\, \text{GeV}/c for D0D^0 and D+D^+ and 1<pT<10GeV/c1 < p_{\text{T}} < 10\, \text{GeV}/c for Ds+D_s^+ and D+D^{*+} mesons. The inclusive cross-sections for the four mesons, including charge-conjugate states, within the range of 1<pT<8GeV/c1 < p_{\text{T}} < 8\, \text{GeV}/c are determined to be \begin{equation*} \sigma(pp\rightarrow D^0 X) = 1190 \pm 3 \pm 64\,\mu\text{b} \end{equation*} \begin{equation*} \sigma(pp\rightarrow D^+ X) = 456 \pm 3 \pm 34\,\mu\text{b} \end{equation*} \begin{equation*} \sigma(pp\rightarrow D_s^+ X) = 195 \pm 4 \pm 19\,\mu\text{b} \end{equation*} \begin{equation*} \sigma(pp\rightarrow D^{*+} X)= 467 \pm 6 \pm 40\,\mu\text{b} \end{equation*} where the uncertainties are statistical and systematic, respectively.Production cross-sections of prompt charm mesons are measured using data from pp collisions at the LHC at a centre-of-mass energy of 5 TeV. The data sample corresponds to an integrated luminosity of 8.60 ± 0.33 pb1^{−1} collected by the LHCb experiment. The production cross-sections of D0^{0}, D+^{+}, Ds+_{s}^{+} , and D+^{∗+} mesons are measured in bins of charm meson transverse momentum, pT_{T}, and rapidity, y.
