The Landscape of Reason: A Scheme for Representing Arguments Concerning Environmental, Health and Safety Effects of Chemical Weapons Disposal in the US

To reduce the risk of environmental contamination and honor an international treaty, chemical weapons stored at eight locales around the US are slated for destruction. Incineration is the main choice of a National Research Council committee directed by Congress to weigh the hazards of alternative destruction technologies, but many citizens\u27 groups remain unconvinced. The US Army, which must dispose of the dangerous chemicals, faces decisions about the choice of destruction technologies, as well as more specific questions concerning protection of environment, safety and public health once the technology choices are made. Based on more than 200 individual interviews and 40 focus groups held in communities near where the weapons are stored, this paper illustrates an argumentation scheme for representing the underlying reasons for varying positions in the conflict over technology choices. The argumentation scheme is effective in representing qualitative interview data concerning the complex and dynamic environmental perspectives of diverse regional and national constituencies

Synergistic effects of bombesin and epidermal growth factor on cancers.

Bombesin and gastrin-releasing peptide act as autocrine mitogens in various cancers. Bombesin antagonist RC-3095 inhibited growth in some cancers and slowed the progression of premalignant lesions, possibly by down-regulating epidermal growth factor (EGF) receptors. Since the EGF receptor mitogen response involves tyrosine kinase stimulation, we tested the hypotheses that bombesin stimulates, and RC-3095 inhibits, phosphorylation; EGF and bombesin promote the phosphorylation of the same substrates; and EGF and bombesin act synergistically on phosphorylation. Therefore, in vitro assays for phosphorylation were performed in the presence or absence of EGF, bombesin, RC-3095, and combinations in samples derived from tumor, tissue surrounding tumor, cell lines, and normal and transforming tissue derived from the 9,10-dimethyl-1,2-benzanthracene-induced squamous cell lesions of the hamster cheek pouch. Bombesin increased, and RC-3095 decreased, phosphorylation in these samples. In the human hepatoma sample and surrounding tissue, these ligands altered the phosphorylation of the same substrates affected by EGF. EGF and bombesin stimulated phosphorylation synergistically in the hamster samples and the hepatoma. Bombesin-induced phosphorylation was greater in tissue surrounding the hepatoma, whereas RC-3095 was more effective in inhibiting phosphorylation in the hepatoma itself. This cancer, therefore, could be endogenously stimulated by gastrin-releasing peptide. These observations support the hypothesis that bombesin stimulates growth of tissues and tumors by amplifying the phosphorylation response to EGF. The growth inhibitory response to RC-3095, or other bombesin analogues, of individual tumors may be prognosed by in vitro phosphorylation assays using the samples from the patient's tumor

Pulmonary Sclerosing Hemangioma Detected by Fluorodeoxyglucose Positron Emission Tomography in Familial Adenomatous Polyposis: Report of a Case

We present a 53-year-old female suffering from familial adenomatous polyposis, who was found to have a positive nodus, lateral to the hilus of the left lung, on routine FDG-PET scan. This lesion was found to be a sclerosing hemangioma. We found an aberrant β-catenin expression on immunohistochemical staining, suggesting that sclerosing hemangioma and familial adenomatous polyposis share the same pathophysiology. It is important to be aware of the association of familial adenomatous polyposis and sclerosing hemangioma

Lifestyle gambling, indebtedness and anxiety: A deviant leisure perspective

While once subject to wide-ranging state control, gambling has successfully culturally embedded itself within the normalised and legitimised forms of leisure such as the night-time economy, sports fandom and online forums of socialisation. Consequently, this article argues that existing research which conceptualises gambling as separate from everyday life is largely obsolete in the contemporary context. We argue here that gambling has become an integral feature of the wider masculine weekend leisure experience, intimately connected to an infantilised consumer identity that is peculiar to late-capitalism. This article, drawing upon ongoing ethnographic research among what we term ‘lifestyle gamblers’, utilises a deviant leisure perspective to problematise the myriad harms that emerge from this relationship, situated within a broader critique of consumerism and global capitalism. While social gambling is defended fiercely by the industry, this article argues that an identity-based culture of sports-betting that attaches fragile social and cultural capital to the allure of the gambling win encourages the chasing of losses and impulsive betting. Underscored by a culture of readily available and high-interest credit, we explore how gamblers in a technologically accelerated culture develop a pathological relationship to money as it becomes desublimated and loses its symbolic value. Such processes, exacerbated by the promise of consumer culture, have the potential to cast these young adults into a paralysing reality of indebtedness that is fraught with depression, stress, domestic instability and destructive behaviours of consumption
