Resisting “national breast cancer awareness month”: the rhetoric of counterpublics and their cultural performances     

Phaedra C. Pezzullo 《Quarterly Journal of Speech》2013,99(4):345-365

Since 1984, October has been recognized in the U.S. as National Breast Cancer Awareness Month. In 1997, the Toxic Links Coalition of the Bay Area, California, began organizing annual “Stop Cancer Where It Starts” tours to counter attempts to obscure the environmentally-linked causes of cancer. By drawing on research including participant observation, this essay analyzes the politics of these two publics in an attempt to illustrate the limits of a binary conceptualization of publics and counterpublics and to emphasize the rhetorical value of the cultural performances that constitute public life.  相似文献

The effects of a home-based physical activity intervention on cardiorespiratory fitness in breast cancer survivors; a randomised controlled trial

The aim of this current randomised controlled trial was to evaluate the effects of a home-based physical activity (PA) intervention on cardiorespiratory fitness in breast cancer survivors. Thirty-two post-adjuvant therapy breast cancer survivors (age = 52 ± 10 years; BMI = 27.2 ± 4.4 kg?m²) were randomised to a six-month home-based PA intervention with face-to-face and telephone PA counselling or usual care. Cardiorespiratory fitness and self-reported PA were assessed at baseline and at six-months. Participants had a mean relative V?O₂max of 25.3 ± 4.7 ml?kg^?1?min^?1, which is categorised as “poor” according to age and gender matched normative values. Magnitude-based inference analyses revealed likely at least small beneficial effects (effect sizes ≥.20) on absolute and relative V?O₂ max (d = .44 and .40, respectively), and total and moderate PA (d = .73 and .59, respectively) in the intervention compared to the usual care group. We found no likely beneficial improvements in any other outcome. Our home-based PA intervention led to likely beneficial, albeit modest, increases in cardiorespiratory fitness and self-reported PA in breast cancer survivors. This intervention has the potential for widespread implementation and adoption, which could considerably impact on post-treatment recovery in this population.  相似文献   

Glycoprotein components in the serum of patients with cancer breast     

Miriam Varkey  R. Sundara Devi  Shrinivas B. Rao 《Indian journal of clinical biochemistry : IJCB》1997,12(1):63-66

The levels of total sialic acid, lipid bound sialic acid and fucose were estimated in the sera of patients with benign and malignant tumours of breast. An increase was noted in all the three parameters, with a more marked increase in malignancy, when compared with benign and controls. Consequent to surgery, there was an elevation in the serum levels of the above parameters than the values prior to surgery and a decline was noted two months after surgery although none of the values reached the normal range. These results suggest a close association of the glycoproteins with the tumour burden and further signify their role in early detection and staging of cancer breast.  相似文献   

UFCI基因在乳腺细胞系中的表达分析     

贺爱兰  张梦成  彭东海 《娄底师专学报》2011,(2):79-81

泛素结合酶UFC1是一个新鉴定的类似泛素结合酶E2的基因。目前,对UFC1的功能研究报道还比较少,有待更进一步的研究和探讨。采用半定量RT-PCR技术分别检测一系列的乳腺细胞系MCF7、HBL100、MDA-MB231和MDA-MB-453中UFC1基因的转录水平,结果显示,在正常的HBL100乳腺细胞系中的表达最高,而在乳腺癌细胞系MCF7,MDA-MB231,MDA-MB-453中的表达明显降低。UFC1在乳腺细胞系中的差异表达的结果为将UFC1作为新的靶分子引入乳腺癌的临床预防和治疗提供实验依据。  相似文献   

乳腺癌中mRNA结合蛋白IMP3表达差异的研究     

杜艳  王英  赵华  葛芹玉 《南京晓庄学院学报》2011,(6):64-68

IMP3（胰岛素生长因子Ⅱ的mRNA的结合蛋白3）是一个新发现的癌胚胎的RNA结合蛋白,研究发现其参与细胞生长和细胞迁移在胚胎发育的早期阶段．该研究利用实时定量逆转录PCR对IMP3在乳腺癌的诊断和治疗中的应用潜力进行了研究和评估．检测了不同类型乳腺癌样本中IMP3的表达情况,定量PCR结果分析中应用2也小。方法进行了归一化比较．研究结果表明,IMP3基因表达与乳腺癌病人肿瘤的大小及淋巴转移存在明显的相关性（P〈0．01）．不同的临床阶段和病理分期与IMP3的表达水平之间也存在一定的相关性,表明差异不显著（P〉0．05）．该研究表明IMP3作为一种新的肿瘤相关因子,其表达水平与乳腺癌也存在一定的相关性,显示了其作为一种潜在的肿瘤标志物的可能性．  相似文献

谷化平  尚培中  胡海霞 《河北北方学院学报(医学版)》1999,(1)

应用免疫组化SP法对94例乳腺癌、41例乳腺良性病变和10例正常乳腺组织进行了细胞粘附分子CD_(15)检测。结果发现,CD_(15)。在乳腺癌和乳腺良性病变的阳性率分别为79.8％和58.3％,两者有显著差异性(P<0 01),10例正常乳腺组织仅4例呈CD_(15)弱阳性反应。CD_(15)表达与患者年龄和肿瘤大小无显著关系。CD_(15)表达阳性率在浸润性导管癌中显著高于单纯癌(P<0.05),组织学Ⅱ～Ⅲ级显著高于Ⅰ级者(P<0.05),临床Ⅲ一Ⅳ期显著高于Ⅰ期和Ⅱ期者(P<0.05),淋巴结转移阳性组显著高于阴性组(P<0.01)。在一组原发部位和淋巴结转移性乳腺癌配对标本中,CD_(15)表达无明显差异性。CD_(15)阳性的乳腺癌Cath-D和c-erbB-2的表达阳性率均显著高于CD_(15)阴性者(P<0.001)。结果提示,CD_(15)的表达与乳腺癌的发生发展、浸润转移及预后有密切关系。  相似文献
