Effects of Mass and Interpersonal Communication on Breast Cancer Screening: Advancing Agenda-Setting Theory in Health Contexts     

Karyn Ogata Jones  Bryan E. Denham  Jeffrey K. Springston 《Journal of Applied Communication Research》2006,34(1):94-113

Drawing on components of agenda-setting theory and the two-step flow of information from mass media to news audiences, this study examines the effects of mass and interpersonal communication on breast cancer screening practices among college- and middle-aged women (n = 284). We theorized that screening behaviors among younger women would be influenced more by interpersonal sources of information while screening among middle-aged women would be more influenced by exposure to mass-mediated information. Findings supported anticipated patterns, revealing important and varying roles for both mass and interpersonal communication in the health behaviors of women. Implications for health practitioners and campaign planners, as well as recommendations for future research, are discussed.  相似文献

Clinical usefulness of alterations in sialic acid,sialyl transferase and sialoproteins in breast cancer     

G. N. Raval  L. J. Parekh  D. D. Patel  F. P. Jha  R. N. Sainger  P. S. Patel 《Indian journal of clinical biochemistry : IJCB》2004,19(2):60-71

Sialic acid, the end moieties of the carbohydrate chains are biologically important and essential for functions of glycoconjugates and are reported to be altered in cancer patients. Two hundred and twenty five breast cancer (BC) patients, 100 patients with benign breast disease (BBD) and 100 healthy females (controls) were enrolled for the study. Eight hundred and twenty four follow-up samples of 225 breast carcinoma patients were also evaluated. The association of sialic acid forms, sialyltransferase and α-2–6 sialoproteins levels with presence and extent as well as prognosis of breast carcinoma was studied. Serum sialic acid forms and sialyltransferase revealed significantly elevated levels among untreated breast cancer patients as compared to the controls, patients with BBD as well as cancer patients in remission. Non-responders showed comparable levels of the markers with those found in breast cancer patients at the time of diagnosis. Higher levels of sialic acid forms at diagnosis were associated with poor prognosis. A positive correlation between serum levels of different forms of sialic acids and extent of malignant disease was observed. The changes in serum proteins with terminal α-2–6 sialic acid correlated well with alterations in the levels of sialic acid forms and sialyltransferase. Malignant tissues showed elevated levels of sialic acid and sialyltransferase as compared to surrounding normal tissues. The results suggested potential utility of these markers in evaluation of clinical outcome.  相似文献   

论庄子视野中的理想人格   总被引：2，自引：0，他引：2  

徐春根 《嘉应学院学报》2007,25(1):42-45

庄子坚持从“他人为尊”、与人为善的“以鸟养养鸟”人格立场出发,追求人格的完善、独立和自由。庄子认为,要真正实现人格的完善、独立和自由,就必须挣脱物质和人身的依附关系,过平易恬淡的生活,不因所谓人生的辉煌腾达而改变自己高洁的志向,也不因生活窘困而变得庸俗不堪;并且,还必须在此基础上,进一步参透生死,依据自然的内在法则傲立于天地之间,从宇宙大道的立场观照死,从而达至内在与外在、天与人的和谐圆融的审美理想人格。庄子审美理想人格不是现实人格的简单复制或摹仿,它导源于、却又超越于现实生活中的各种人格,这本身彰显了庄子某种积极“入世”的对于社会民生困境与出路的深层关切。  相似文献

Breast cancer in developing population: A nutrition caveat     

Garima Mehta  Seema Kothari  P. P. Singh 《Indian journal of clinical biochemistry : IJCB》2001,16(1):65-71

From January 1992-January 1998, 1404 patients attended the “Breast Clinic” of R.N.T. Medical College M.B. Hospital, Udaipur. Out of these, 11% and 81% patients had breast cancer (B.C.) and benign breast cancer (B.B.D.) respectively. The oxidative load in B.C. was 2.32 times higher than controls, but comparable to B.B.D. β-Carotene deficiency was uncommon in patients, whereas vitamin A deficiency was almost equally common in both B.C. and controls. Most of the patients had almost depleted levels of α-tocopherol and ascorbic acid but their TBAR levels were in normal range. The data in the present study when compared with B.B.D. and other local normal subjects point out: a) oxidative burden in B.C. is a consequence and not the cause of the disease, (b) oxidative stress could be one of the etiological factors in tumor expression, which need not to be malignant and c) α-tocopherol and ascorbic acid are not importantly responsible for higher oxidative burden in B.C.  相似文献   

Serum total PSA and free PSA in breast tumors     

Dash P  Pati S  Mangaraj M  Sahu PK  Mohapatra PC 《Indian journal of clinical biochemistry : IJCB》2011,26(2):182-186

Now a days measurement of molecular forms of PSA has gained importance in clinical practice. Several studies have demonstrated the production of PSA in female tissues, such as breast. The present piece of work has been undertaken with an objective to estimate the relative proportion of the molecular forms of PSA in serum along with serum testosterone in benign and malignant breast tumor cases and to analyze their association with the severity of the disease process 34 malignant and 26 benign breast disease cases along with 33 healthy controls of same age group were enrolled in this study for evaluation. Serum testosterone was measured by ELISA, whereas serum total PSA (TPSA) and free PSA (FPSA) were estimated by electrochemiluminescence immunoassay. A significant rise of fasting plasma glucose along with prominent dyslipidemia was observed in breast tumor cases. Marked rise in serum testosterone as well as TPSA and FPSA was documented in both benign and malignant breast tumor cases. Serum testosterone revealed a significant positive association with both TPSA and FPSA pointing towards an etiological association between them. However, surgical removal of tumor mass resulted in a marked decline of presurgical value of both TPSA and FPSA with a non-significant fall in serum testosterone revealing tumor tissue as the source of FPSA and TPSA. Thus, estimation of PSA provides prognostic information that may assist in future treatment.  相似文献
