Measurement of paraben concentrations in human breast tissue at serial locations across the breast from axilla to sternum

The concentrations of five esters of p-hydroxybenzoic acid (parabens) were measured using HPLC-MS/MS at four serial locations across the human breast from axilla to sternum using human breast tissue collected from 40 mastectomies for primary breast cancer in England between 2005 and 2008. One or more paraben esters were quantifiable in 158/160 (99%) of the tissue samples and in 96/160 (60%) all five esters were measured. Variation was notable with respect to individual paraben esters, location within one breast and similar locations in different breasts. Overall median values in nanograms per gram tissue for the 160 tissue samples were highest for n-propylparaben [16.8 (range 0–2052.7)] and methylparaben [16.6 (range 0–5102.9)]; levels were lower for n-butylparaben [5.8 (range 0–95.4)], ethylparaben [3.4 (range 0–499.7)] and isobutylparaben 2.1 (range 0–802.9). The overall median value for total paraben was 85.5 ng g−1 tissue (range 0–5134.5). The source of the paraben cannot be identified, but paraben was measured in the 7/40 patients who reported never having used underarm cosmetics in their lifetime. No correlations were found between paraben concentrations and age of patient (37–91 years), length of breast feeding (0–23 months), tumour location or tumour oestrogen receptor content. In view of the disproportionate incidence of breast cancer in the upper outer quadrant, paraben concentrations were compared across the four regions of the breast: n-propylparaben was found at significantly higher levels in the axilla than mid (P = 0.004 Wilcoxon matched pairs) or medial (P = 0.021 Wilcoxon matched pairs) regions (P = 0.010 Friedman ANOVA).

From apotheosis to damnation: Mussolini and the Fascist regime, 1936-45

This is an essay for a catalogue of the exhibition 'Against Mussolini: art and the fall of a dictator' held at the Estorick Collection, London, September - December 2010. The essay examines shifting attitudes towards Mussolini in the years immediately preceding his fall, and suggests that the development of 'anti-fascism' was less pronounced than often suggested.

From hieroglyphics to Isotype: a visual autobiography (Otto Neurath)

Otto Neurath (1882–1945) wrote From hieroglyphics to Isotype during the last two years of his life and this is the first publication of the text in full, carefully edited from the original manuscripts. He called it a 'visual autobiography', in which he documents the importance of visual material to him from his earliest years to his professional activity with the picture language of Isotype. Neurath draws clear links between the stimulus he received as a boy from illustrated books, toys and exhibitions to the considered work in visual education that occupied him for the last two decades of his life. This engaging and informal account gives a rich picture of Central European culture around the turn of the twentieth century, seen through the eyes of Neurath's insatiable intelligence, as well as a detailed exposition of the technique of Isotype, a milestone of modern graphic design. This edition includes the numerous illustrations intended by Neurath to accompany his text, and is completed by an extensive appendix showing examples from the rich variety of graphic material that he collected.

Revisiting the Earth's sea-level and energy budgets from 1961 to 2008

We review the sea-level and energy budgets together from 1961, using recent and updated estimates of all terms. From 1972 to 2008, the observed sea-level rise (1.8 ± 0.2 mm yr−1 from tide gauges alone and 2.1 ± 0.2 mm yr−1 from a combination of tide gauges and altimeter observations) agrees well with the sum of contributions (1.8 ± 0.4 mm yr−1) in magnitude and with both having similar increases in the rate of rise during the period. The largest contributions come from ocean thermal expansion (0.8 mm yr−1) and the melting of glaciers and ice caps (0.7 mm yr−1), with Greenland and Antarctica contributing about 0.4 mm yr−1. The cryospheric contributions increase through the period (particularly in the 1990s) but the thermosteric contribution increases less rapidly. We include an improved estimate of aquifer depletion (0.3 mm yr−1), partially offsetting the retention of water in dams and giving a total terrestrial storage contribution of −0.1 mm yr−1. Ocean warming (90% of the total of the Earth's energy increase) continues through to the end of the record, in agreement with continued greenhouse gas forcing. The aerosol forcing, inferred as a residual in the atmospheric energy balance, is estimated as −0.8 ± 0.4 W m−2 for the 1980s and early 1990s. It increases in the late 1990s, as is required for consistency with little surface warming over the last decade. This increase is likely at least partially related to substantial increases in aerosol emissions from developing nations and moderate volcanic activity

From matron to matrix: gender, authority and (dis)embodiment in Beckett’s Theatre

An examination of Samuel Beckett's representation of women in a selection of his plays for stage and radio.

From saccades to smooth pursuit: real-time gaze control using motion feedback

The authors present an active vision system which performs a surveillance task in everyday dynamic scenes. The system is based around simple, rapid motion processors and a control strategy which uses both position and velocity information. The surveillance task is defined in terms of two separate behavioral subsystems, saccade and smooth pursuit, which are demonstrated individually on the system. It is shown how these and other elementary responses to 2D motion can be built up into behavior sequences, and how judicious close cooperation between vision and control results in smooth transitions between the behaviors. These ideas are demonstrated by an implementation of a saccade to smooth pursuit surveillance system on a high-performance robotic hand/eye platform.

The Gift of the Nile: Hellenizing Egypt from Aeschylus to Alexander

The Egyptians mesmerized the ancient Greeks for scores of years. The Greek literature and art of the classical period are especially thick with representations of Egypt and Egyptians. Yet despite numerous firsthand contacts with Egypt, Greek writers constructed their own Egypt, one that differed in significant ways from actual Egyptian history, society, and culture. Informed by recent work on orientalism and colonialism, this book unravels the significance of these misrepresentations of Egypt in the Greek cultural imagination in the fifth and fourth centuries B.C.E. Looking in particular at issues of identity, otherness, and cultural anxiety, Phiroze Vasunia shows how Greek authors constructed an image of Egypt that reflected their own attitudes and prejudices about Greece itself. He focuses his discussion on Aeschylus Suppliants; Book 2 of Herodotus; Euripides' Helen; Plato's Phaedrus, Timaeus, and Critias; and Isocrates' Busiris. Reconstructing the history of the bias that informed these writings, Vasunia shows that Egypt in these works was shaped in relation to Greek institutions, values, and ideas on such subjects as gender and sexuality, death, writing, and political and ethnic identity. This study traces the tendentiousness of Greek representations by introducing comparative Egyptian material, thus interrogating the Greek texts and authors from a cross-cultural perspective. A final chapter also considers the invasion of Egypt by Alexander the Great and shows how he exploited and revised the discursive tradition in his conquest of the country. Firmly and knowledgeably rooted in classical studies and the ancient sources, this study takes a broad look at the issue of cross-cultural exchange in antiquity by framing it within the perspective of contemporary cultural studies. In addition, this provocative and original work shows how Greek writers made possible literary Europe's most persistent and adaptable obsession: the barbarian.
