A novel alternative. Book groups, women, and workplace networking

Drawing on the results of a small qualitative research project involving four work-based book groups – three in the UK and one in the USA- this article examines the ways in which participation in workplace reading groups facilitates women’s networking within work organizations, in terms of both formal and informal as well as expressive and instrumental networking. It has long been recognized that women’s employment progression is hampered, in part, by their exclusion from male-dominated networks. Taking a gendered approach to the analysis of workplace networking, this study suggests that book groups can function as an alternative to traditional old boys’ networks, in some instances. Within the workplace the collective reading of literature, I suggest, can potentially function as a means to extend the social as well as the more career-focused opportunities of its participants

Aesthetic surgery and the expressive body

In this paper we explore the relation between bodies and selves evident in the narratives surrounding aesthetic surgery. In much feminist work on aesthetic surgery such narratives have been discussed in terms of the normalising consequences of the objectifying, homogenising, cosmetic gaze. These discussions stress the ways in which we model our bodies, under the gaze of others, in order to conform to social norms. Such an objectified body is contrasted with the subjective body; the body –for –the self. In this paper, however, we wish to make sense of the narratives surrounding such surgery by invoking the expressive body, which fits on neither side of this binary. We wish to explore how the modification of the body’s anatomical features (physiology) are taken to be a modification of its expressive possibilities, and therefore as modifications of possibilities for inter-subjective relations with others. It is such expressive possibilities, which, we suggest, underlie decisions to undergo surgical procedures. The possibility of modification of the expressive possibilities of the body, by the modification of its anatomical features, rests on the social imaginaries attached to anatomical features. In the context of such imaginaries individual decisions to undergo or promote surgery can be both intelligible and potentially empowering. However, the social consequences of such acts are an increasing normalisation of the ‘body under the knife’ and an intolerance of bodily difference. This, we suggest, can only be changed by a re-visioning of bodily imaginaries so that expressive possibilities can be experienced across bodies with a range of physiological features

Disordered clusters of Bak dimers rupture mitochondria during apoptosis

During apoptosis, Bak and Bax undergo major conformational change and form symmetric dimers that coalesce to perforate the mitochondrial outer membrane via an unknown mechanism. We have employed cysteine labelling and linkage analysis to the full length of Bak in mitochondria. This comprehensive survey showed that in each Bak dimer the N-termini are fully solvent-exposed and mobile, the core is highly structured, and the C-termini are flexible but restrained by their contact with the membrane. Dimer-dimer interactions were more labile than the BH3:groove interaction within dimers, suggesting there is no extensive protein interface between dimers. In addition, linkage in the mobile Bak N-terminus (V61C) specifically quantified association between dimers, allowing mathematical simulations of dimer arrangement. Together, our data show that Bak dimers form disordered clusters to generate lipidic pores. These findings provide a molecular explanation for the observed structural heterogeneity of the apoptotic pore

Resistance of Renal Cell Carcinoma to Sorafenib Is Mediated by Potentially Reversible Gene Expression

Purpose: Resistance to antiangiogenic therapy is an important clinical problem. We examined whether resistance occurs at least in part via reversible, physiologic changes in the tumor, or results solely from stable genetic changes in resistant tumor cells. Experimental Design: Mice bearing two human RCC xenografts were treated with sorafenib until they acquired resistance. Resistant 786-O cells were harvested and reimplanted into naïve mice. Mice bearing resistant A498 cells were subjected to a 1 week treatment break. Sorafenib was then again administered to both sets of mice. Tumor growth patterns, gene expression, viability, blood vessel density, and perfusion were serially assessed in treated vs control mice. Results: Despite prior resistance, reimplanted 786-O tumors maintained their ability to stabilize on sorafenib in sequential reimplantation steps. A transcriptome profile of the tumors revealed that the gene expression profile of tumors upon reimplantation reapproximated that of the untreated tumors and was distinct from tumors exhibiting resistance to sorafenib. In A498 tumors, revascularization was noted with resistance and cessation of sorafenib therapy and tumor perfusion was reduced and tumor cell necrosis enhanced with re-exposure to sorafenib. Conclusions: In two RCC cell lines, resistance to sorafenib appears to be reversible. These results support the hypothesis that resistance to VEGF pathway therapy is not solely the result of a permanent genetic change in the tumor or selection of resistant clones, but rather is due to a great extent to reversible changes that likely occur in the tumor and/or its microenvironment
