Keratins represent the principal structural proteins of hair. They are also found in horn, nail, claw, hoof, and feather. Hair and nail samples from human and canine sources and hair samples from mule deer, white tail deer, cat, moose, elk, antelope, caribou, raccoon, and goat were studied. Parrot and goose feathers were also analyzed. Keratins are polymorphic, and species differences are known to exist. Proteinaceous extracts of deer and antelope antlers and bovine and rhinoceros horn were prepared by solubilizing 10 mg of horn sample in 200 microL of a solution containing 12M urea, 74mM Trizma base, and 78mM dithiothreitol (DTT). Extraction took place over a 48-h period. A 25-microL aliquot of extract was removed and incubated with 5 microL of 0.1 M DTT for 10 min at 25 degrees C. Keratins were then separated by isoelectric focusing (IEF) on 5.2% polyacrylamide gels for 3 h and visualized using silver staining. At least 20 bands could be observed for each species studied. However, band patterns differed in the position of each band, in the number of bands, and in band coloration resulting from the silver staining process. Horn from two species of rhinoceros was examined. For both specimens, most bands occurred in the pH range of 4 to 5. Although similar patterns for both species were observed, they differed sufficiently to differentiate one from the other. As might be expected, the closer two species are related phylogenetically, the greater the similarity in the IEF pattern produced from their solubilized keratin.(ABSTRACT TRUNCATED AT 250 WORDS) 相似文献

ABSTRACTViews of people involved in the commercial sex trade have shifted. Once seen as prostitutes or “whores,” they are increasingly perceived as exploited “victims.” The behavior associated with commercial sex has been redefined from voluntary and disreputable to coerced and deserving of rescue. This new framework is part of a broader anti-trafficking movement in society to recognize and save vulnerable individuals who are exploited for sex. In this context, the model of problem-solving or specialty courts has been extended to sex trafficking cases. The goal first is to identify trafficking victims–also known as “victim-defendants”–and then to address their risk factors with services. The current review examines the prevalence and the effectiveness of sex trafficking courts. Although some promising evaluations have been conducted, it remains unclear whether such courts are addressing the unique needs of victim-defendants. Investigating this question is essential, given that trafficking courts are likely to grow in popularity and in number. 相似文献

Canadian women have been at the forefront of the international movement for women's rights in Afghanistan since the rise of the Taliban in the late 1990s. Focusing on the prominent group Canadian Women for Women in Afghanistan (CW4WAfghan), this paper looks at the role its advocacy assumes in the context of the ‘War on Terror’. In Canada, as in the United States, government agencies have justified the military invasion of Afghanistan by revitalizing the oppressed Muslim woman as a medium through which narratives of East versus West are performed. While CW4WAfghan attempts to challenge dominant narratives of Afghan women, it ultimately reinforces the Orientalist logic on which the War on Terror operates. Drawing on Chandra Talpade Mohanty's study of feminist pedagogy, this paper explores the implications of CW4WAfghan's discourse and its dissemination through the Canadian school system. It highlights how CW4WAfghan's portrayal of Canadian values and responsibilities is at odds with feminist efforts to reconceptualize the gendered nature of war and national identity. 相似文献

Male prison rape and sexual assaults remains a serious and sensitive issue in many countries. Human rights groups claim that sexual assaults among male prisoners have reached pandemic proportions and need to be stopped. Researchers for many years have studied the causes of male sexual assault in prison and offered numerous recommendations on its prevention. Few, however, have presented evidence for a decline in male prisoner sexual assaults and investigated the reasons for the decline. This article provides evidence from population-based surveys of a steady decrease in male prisoner sexual assaults in New South Wales (NSW) between 1996 and 2009. The authors conducted in-depth interviews with former and current inmates, and using a "systems" approach they discuss the complexity of sexual assaults in prison, incorporating a multiplicity of perspectives. In particular, they bring together different sources of data and discuss this in relation to changes in power structures and control in a modern prison, the attitudes of older and younger prisoners, the concept of "duty of care," introduction of prison drug programs, and prisoner attitudes toward gender and sexuality. In anthropology, the term "system" is used widely for describing sociocultural phenomena of a given society in a holistic manner without reducing the complexity of a given community. 相似文献
