Pregnancy Loss,Skin-Based Body Modifications and Agency

This article utilizes notions of ‘agency’ to explore the relationship between experiences of pregnancy loss and narratives about related skin-based body modifications. The term ‘pregnancy loss’ is used to denote a range of medical events with potentially far-reaching emotional and social consequences. The research from which the empirical content of this article is drawn seeks to bring together feminist interests and the discipline of human geography to examine experiences of pregnancy loss. Different aspects regarding ‘agency’ are attended to through several practices—namely, the acquisition, display/concealment and narration of skin-based bodily marks like stretch marks and memorial tattoos. This includes a discussion on notions of ‘choice’ in terms of receiving/acquiring changes to the skin through pregnancy and pregnancy loss, regarding which stretch marks and tattoos are often pitted as oppositional. A more complex picture of agency is explored and illustrated with the narratives of several women with pregnancy-loss experiences, highlighting that both kinds of skin-based modifications can be framed in more agential ways, including as appreciated reminders of simultaneous love and loss. In doing so, this article constitutes an attempt to engage with pregnancy loss from a feminist perspective, as encouraged by Linda Layne, and to contribute to feminist scholarship on body modifications.     

Translation and ideology

This article attempts to investigate, in depth, the concept of ideology in translation. That is to say, the extent to which ideology can influence the translator's style and choice of words that will, consequently, shape the receivers’ worldviews. In recent years the issue of ideological leanings and the implications of ideology on translation have received particular attention. Owing to the importance of this issue of ideology, and as an example of the issues that both the translating practitioner and theorist must deal with, this article provides a detailed, comparative analysis of a translation of the first, formal speech delivered by bin Laden on 7 October 2001 concerning the events of September 11 and his conflict with the United States. The analysis assesses the probability of a translator's ideological intervention in the text and other technical, linguistic problems.     

Effectiveness of a Cancer Education Program for Women Attending Rural Public Health Departments in North Carolina

SUMMARY

The Western North Carolina Cancer Awareness Program (CAP) was a four-year program, funded by the National Cancer Institute, to increase education and support services for the prevention and early detection of breast, cervical, and skin cancer among women receiving care in six rural county public health departments. Three health departments were selected as intervention units, and the remaining three health departments served as comparison units. Women age 20 and older were randomly selected in each health department. Women in the intervention group received a comprehensive health education program that included easy-to-read printed materials and telephone counseling dealing with breast, cervical, and skin cancer. Theoretical guidelines for development of the intervention program included the PRECEDE Model and the Health Belief Model. Overall, the results indicated that personalized education, which includes the combination of readable printed materials and telephone contact, can be effective in increasing some early detection behaviors for breast and skin cancer among women who attend public health departments. The value of telephone counseling as a comparatively inexpensive approach to individualizing health education has significant implications for the development of similar cancer education programs for underserved populations.     

Staphylococcal scalded skin syndrome mimicking child abuse by burning

Child abuse by burning comprises 6–20% of all child abuse cases, but misdiagnosis may arise in cases of some medical conditions. We present two cases of suspected inflicted burns, later diagnosed as staphylococcal scalded skin syndrome (SSSS).

小鼠皮肤切创愈合过程中Ⅱ型大麻素受体的表达

目的观察皮肤切创愈合过程中CB2R表达变化的时问规律性。方法 健康小鼠50只,随机分为10组,建立皮肤切创模型,应用免疫组织化学技术及Westernbloting方法检测切创后不同时间段小鼠背部正中皮肤CB2R的表达。结果免疫组织化学结果显示,对照组CB2R表达于表皮、毛囊、皮脂腺、皮肌层、血管平滑肌、神经纤维外膜及神经纤维束束膜;伤后6h损伤区及周边区多核粒细胞少量表达CB2R,12～24h以单个核细胞阳性表达为主,3d以单个核细胞和梭形成纤维细胞表达为主,5～14d以梭形成纤维细胞为主。CB2R阳性细胞率于0h～3d逐渐升高,5d达最高峰,随后逐渐下降。经Westernblotting检测显示,对照及各个损伤时间段都有CB2R阳性条带,其中5d为CB2R表达高峰。结论小鼠皮肤切创愈合过程中,CB2R于损伤区及周边区多核粒细胞、单个核细胞、梭形成纤维细胞中表达,并具有规律性,提示CB2R可能参与皮肤损伤愈合,并可用于皮肤损伤时间的推断。
