The Escherichia coli O157:H7 EhaB autotransporter protein binds to laminin and collagen I and induces a serum IgA response in O157:H7 challenged cattle

Enterohaemorrhagic Escherichia coli (EHEC) are a subgroup of Shiga toxin-producing E. coli that cause gastrointestinal disease with the potential for life-threatening sequelae. Cattle serve as the natural reservoir for EHEC and outbreaks occur sporadically as a result of contaminated beef and other farming products. While certain EHEC virulence mechanisms have been extensively studied, the factors that mediate host colonization are poorly defined. Previously, we identified four proteins (EhaA,B,C,D) from the prototypic EHEC strain EDL933 that belong to the autotransporter (AT) family. Here we characterize the EhaB AT protein. EhaB was shown to be located at the cell surface and overexpression in E. coli K-12 resulted in significant biofilm formation under continuous flow conditions. Overexpression of EhaB in E. coli K12 and EDL933 backgrounds also promoted adhesion to the extracellular matrix proteins collagen I and laminin. An EhaB-specific antibody revealed that EhaB is expressed in E. coli EDL933 following in vitro growth. EhaB also cross-reacted with serum IgA from cattle challenged with E. coli O157:H7, indicating that EhaB is expressed in vivo and elicits a host IgA immune response.

Uropathogenic Escherichia coli mediated urinary tract infection

Urinary tract infection (UTI) is among the most common infectious diseases of humans and is the most common nosocomial infection in the developed world. They cause significant morbidity and mortality, with approximately 150 million cases globally per year. It is estimated that 40-50% of women and 5% of men will develop a UTI in their lifetime, and UTI accounts for more than 1 million hospitalizations and $1.6 billion in medical expenses each year in the USA. Uropathogenic E. coli (UPEC) is the primary cause of UTI. This review presents an overview of the primary virulence factors of UPEC, the major host responses to infection of the urinary tract, the emergence of specific multidrug resistant clones of UPEC, antibiotic treatment options for UPEC-mediated UTI and the current state of vaccine strategies as well as other novel anti-adhesive and prophylactic approaches to prevent UTI. New and emerging themes in UPEC research are also discussed in the context of future outlooks.

Co-branding strategies for luxury fashion brands : Missoni for Target

Missoni is a luxury Italian knitwear brand that partnered with Target in September 2011 releasing a large, one off, mass-market collection that ranged from apparel to home wares. The collaboration received extensive media coverage and was consequently extremely sought after. The online sales site crashed within hours of opening while shelves were cleared in stores minutes after trading began. Within hours more than 40000 items from the collection were posted for sale online at greatly inflated prices. Evaluation of the case study revealed that sales of the Missoni collection increased following the collaboration and the value of the publicity generated at estimated US$100 million. The lack of available stock, despite the enormous hype created, reinforced Missoni’s luxury image. Missoni was able to gain massive awareness of the brand despite not employing any of its own communication channels in the promotion of the collaboration. However the co-branded collaboration was distinctively Missoni, potentially inciting comparison and confusion with the signature line. Nevertheless, this study shows that co-branding strategies can offer a viable opportunity for luxury brands to increase their market share, while they maintain their market position.

2nd ESMO consensus conference on lung cancer : early-stage non-small-cell lung cancer consensus on diagnosis, treatment and follow-up

To complement the existing treatment guidelines for all tumour types, ESMO organises consensus conferences to focus on specific issues in each type of tumour. The 2nd ESMO Consensus Conference on Lung Cancer was held on 11-12 May 2013 in Lugano. A total of 35 experts met to address several questions on non-small-cell lung cancer (NSCLC) in each of four areas: pathology and molecular biomarkers, first-line/second and further lines in advanced disease, earlystage disease and locally advanced disease. For each question, recommendations were made including reference to the grade of recommendation and level of evidence. This consensus paper focuses on early-stage disease. © The Author 2014.

1950s made in Brisbane : Italian tailors and the continental suit

During the 1950s and 1960s, when the French couturiers Dior, Balenciaga, Givenchy and Chanel dominated the fashion industry, the Italian community in Brisbane, Australia, was very active in the local industry through retail, dress-making and tailoring. Australia is geographically at the margins of the developed countries and has been dependent on European trends and taste. In the 1950s, communication was based on magazines and especially newsreels and film; each ethnic group dressed as they liked and according to their custom. Moreover, ‘Made in Italy’ was not yet the prestigious concept that revolutionized ready-to-wear design from the 1970s. However, Italian tailors and demi-couturiers brought to Brisbane their trans-national sense of elegance (the Italian style) and the taste in fashion that influenced new generations in England and elsewhere in Europe from the 1950s. They brought quality and workmanship, offering excellence through the use of quality fabrics from prestigious English and Italian brands. These tailors and dress-makers also contributed towards the local industry through passing on the skills that they brought from Italy. This article is based on a project that seeks to understand the connection between fashion, history and place. The area under examination is the Valley, short for Fortitude Valley, an area adjacent to the Brisbane CBD. Fundamental to this connection between place and fashion was the presence of many Italian migrants in the area. Through archival research and oral history, the aim of this ethnographic project is to bring to the fore an untold story about the economic and aesthetic contribution of Italian migrants to Queensland. Central to the understanding of this aesthetic change is the Italian suit. This research is innovative in that it opens a new area of study in Australian fashion history, connected to the history of migrants and their identity.

Editorial

Welcome to the third issue of Clothing Cultures. We are honoured to have served as the guest editors for this issue. The authors in this issue explore three intersecting themes in using various methods: identity, cross-cultural encounters and everyday practices related to designing, branding and wearing clothing. These themes are at the core of fashion and dress: as an everyday individual and social project, and as a system in which people and objects (clothing) globally circulate. The performance of identity (Goffman 1979; Butler 1990), social practices and the movement of people and commodities (Appadurai 1986, 1996) create and transfer cultural meanings.

Spinning a sustainable yarn : environmental sustainability and brand story in the Australian fashion industry

In the Australian fashion industry, few fashion brands have intervened in the design of their products or the systems around their product to tackle environmental pollution and waste. Instead, support of charities (whether social or environmental) has become conflated with sustainability in the eyes of the public. Thus it is difficult to assess with any accuracy fashion brands’ response to sustainability. This article aims to address this through proposing a categorization system to structure the various interventions that a company may make. This system is applied to two case studies, analysing campaigns that respond to environmental sustainability by two established Australian brands, Country Road and Billabong. The case studies demonstrate how the interventions employed by a company, at least in the Australian context, are carefully developed to align with their brand story, revealing the interplay between the intangible aspects of a brand’s positioning and the tangible, measurable impacts of their garments.

Changing influences on the concept of ‘media influence’

The concept of media influence has a long history in media and communication studies, and has also had significant influence on public policy. This article revisits questions of media influence through three short case studies. First, it critically analyses the strongly partisan position of News Corporation’s newspapers against the Labor government during the 2013 Australian Federal election to consider whether the potential for media influence equated to the effective use of media power. Second, it discusses the assumption in broadcasting legislation, in both the United Kingdom and Australia, that terrestrial broadcasting should be subject to more content regulation than subscription services, and notes the new challenges arising from digital television and over-the-top video streaming services. Finally, it discusses the rise of multi-platform global content aggregators such as Google, Apple, Microsoft and others, and how their rise necessitates changes in ways of thinking about concentration of media ownership, and regulations that may ensue from it.

Evolution of the docklands food hub : a design-led innovation approach to food sovereignty through local food systems

Access to nutritious, safe and culturally appropriate food is a basic human right (Mechlem, 2004). Food sovereignty defines this right through the empowerment of the people to redefine food and agricultural systems, and through ecologically sustainable production methods. At the heart of the food sovereignty movement are the interests of producers, distributors and consumers, rather than the interests of markets and corporations, which dominate the current globalized food system (Hinrichs, 2003). Food sovereignty challenges designers to enable people to innovate the food system. We are yet to develop economically viable solutions for scaling projects and providing citizens, governments and business with tools to develop and promote projects to innovate food systems and promote food sovereignty (Meroni, 2011; Murray, Caulier-Grice and Mulgan, 2010). This article examines how a design-led approach to innovation can assist in the development of new business models and ventures for local food systems: this is presented through an emerging field of research ‘Design-Led Food Communities’. Design-Led Food Communities enables citizens, governments and business to innovate local food projects through the application of design. This article reports on the case study of the Docklands Food Hub Project in Melbourne, Australia. Preliminary findings demonstrate valued outcomes, but also a deficiency in the design process to generate food solutions collaboratively between government, business and citizens.

A Mammalian Circadian Clock Model Incorporating Daytime Expression Elements

Models of the mammalian clock have traditionally been based around two feedback loops-the self-repression of Per/Cry by interfering with activation by BMAL/CLOCK, and the repression of Bmal/Clock by the REV-ERB proteins. Recent experimental evidence suggests that the D-box, a transcription factor binding site associated with daytime expression, plays a larger role in clock function than has previously been understood. We present a simplified clock model that highlights the role of the D-box and illustrate an approach for finding maximum-entropy ensembles of model parameters, given experimentally imposed constraints. Parameter variability can be mitigated using prior probability distributions derived from genome-wide studies of cellular kinetics. Our model reproduces predictions concerning the dual regulation of Cry1 by the D-box and Rev-ErbA/ROR response element (RRE) promoter elements and allows for ensemble-based predictions of phase response curves (PRCs). Nonphotic signals such as Neuropeptide Y (NPY) may act by promoting Cry1 expression, whereas photic signals likely act by stimulating expression from the E/E' box. Ensemble generation with parameter probability restraints reveals more about a model's behavior than a single optimal parameter set.

Collecting in an urban context: Relationships between collections and space in the home

Collecting has become a popular hobby within Western society, with collectables including anything from ‘bottle tops’ to ‘skyscrapers’. As the nature and size of these collections can impact upon the use of space in the home, the purpose of this study is to explore the relationship between the collections, space in the home and the impacts on others. This qualitative study explores the experiences of 11 Australian collectors, investigating the motivations, practices and adaption techniques used within their urban home environment. The themes of sentimentality, sociability and spatial tensions, including physical, personal and use of space are discussed within the context of their home and family environments. Overall the practice of collecting objects is a complex, varied, sentimental and sociable activity, providing enjoyment, knowledge and friendships. Space can be a central consideration to the practice of collecting as collections shape and are shaped by the available space in a household.

Prospective ten-month exercise intervention in premenarcheal girls: Positive effects on bone and lean mass

Enhancement of bone mineral acquisition during growth may be a useful preventive strategy against osteoporosis. The aim of this study was to explore the lean mass, strength, and bone mineral response to a 10-month, high-impact, strength-building exercise program in 71 premenarcheal girls, aged 9–10 years. Lean body mass, total body (TB), lumbar spine (LS), proximal femur (PF), and femoral neck (FN) bone mineral were measured using the Hologic QDR 2000+ bone densitometer. Strength was assessed using a grip dynamometer and the Cybex isokinetic dynamometer (Cybex II). At baseline, no significant difference in body composition, pubertal development, calcium intake, physical activity, strength, or bone mineral existed between groups. At completion, there were again no differences in height, total body mass, pubertal development, calcium intake, or external physical activity. In contrast, the exercise group gained significantly more lean mass, less body fat content, greater shoulder, knee and grip strength, and greater TB, LS, PF, and FN BMD (exercise: TB 3.5%, LS 4.8%, PF 4.5%, and FN 12.0%) compared with the controls (controls: TB 1.2%, LS 1.2%, PF 1.3%, and FN 1.7%). TB bone mineral content (BMC), LS BMC, PF BMC, FN BMC, LS bone mineral apparent density (BMAD), and FN bone area also increased at a significantly greater rate in the exercise group compared with the controls. In multiple regression analysis, change in lean mass was the primary determinant of TB, FN, PF, and LS BMD accrual. Although a large proportion of bone mineral accrual in the premenarcheal skeleton was related to growth, an osteogenic effect was associated with exercise. These results suggest that high-impact, strength building exercise is beneficial for premenarcheal strength, lean mass gains, and bone mineral acquisition.
