The interaction of dendritic cells (DCs) and T cells has been the cornerstone of approaches to cancer immunotherapy. Antitumoral immune responses can be elicited by delivering cancer antigens to DCs. As antigen presenting cells, these DCs activate cancer antigen specific T cells. Whereas the first part of the review discusses methods for delivery of cancer vaccines to DCs, in this part the focus is on the potential role of nanoscopic devices for molecular imaging of these immune responses. Nanoscopic devices could potentially deliver tracking molecules to DCs, enabling monitoring of DCs and/or T cell activation and tumoricidal activity during immunotherapy, using non-invasive imaging modalities such as nuclear imaging (single photon emission computed tomography (SPECT), positron emission tomography (PET)), magnetic resonance imaging (MRI) and optical imaging. 相似文献

Background: Self care of diabetes is essential for control of disease and im-provement of quality of patients' life. The aim of this study was to assess factors influencing self-care practice of patients in urban area of Urmia, Northwest of Iran. Methods: In this cross-sectional study, 400 diabetic patients were randomly selected from eight healthcare centers in Urmia City in 2010. Data collection tools was a questionnaire included data on demographic characteristics, diabetes statues, and self-care practice. Patients' self-care practice was classified to good, moderate, and poor levels. ANOVA and Chi-square tests were used to exam the association between self-care practice and clinical and behavioral factors. Spearman's rho correlation was used to examine the relation between self-care practice and control of glycemia. Results: The patients' self-care practice was good in 15.1%, moderate in 58.7%, and poor in 26.2%. There was a significant association between education (P=0.030), duration of disease (P=0.04), and treatment intensity (P=0.001) and self-care practice of patients. Conclusion: Despite the important role of self-care practice in management of diabetes and preventing its serious complications, most patients who have medical record in health care centers had inappropriate self-care practice especially in SMBG, which has critical role in controlling diabetes. 相似文献

Recently, advances in understanding the etiology of urticaria and updates of diagnostic and therapeutic management guidelines have drawn attention to chronic urticaria (CU) morbidity. The present study aimed to evaluate Iranian dermatologists' practice and real life management of CU patients. A total of 35 dermatologists and 443 patients were included in the study. Number of female patients was 321 (72.5%). Mean (standard deviation) age of the study patients was 38 (13) years and the median (inter quartile range) of disease duration was 12 (6–48) months. Severity of patients' symptoms was mild for 32.1%, moderate for 38.7%, severe for 18.8%, and 10.4% of them had no evident signs or symptoms. The most common diagnostic methods were physical examination (96.6%), differential blood count (83.5%), erythrocyte sedimentation rate (77.4%), and C‐reactive protein (62.8%). The number of dermatologists prescribed nonsedating antihistamines (nsAH) in regular dose and high dose mono therapy were 26 (74%) and 6 (17%), respectively. About 66% of dermatologists were familiar with British Association of Dermatologists (BAD) guideline. The most common first‐line treatment for CU by Iranian dermatologists was nonsedating antihistamines in regular or high doses. The real‐life management of patients with CU in Iran was in accordance with the available practice guidelines. 相似文献

Assessment of the knowledge and attitude of female students towards cervical cancer prevention at an international university in Japan 下载免费PDF全文
Cervical cancer resulting from prior infection with human papillomavirus (HPV) is a significant public health threat against young Japanese women. A national immunization plan to vaccinate 13~16 year old female students against HPV infection has been started in Japan since 2010, and may reach almost full coverage by the end of 2012. Older age females who may already be sexually active are not targeted by this plan but should follow safer sex practices as well as periodic screening of the cervix cytology to reduce their risk of developing cervical cancer. HPV vaccination alone does not offer full protection either, because only some HPV types are covered by the vaccines and the long-term efficacy of the vaccines has not been determined yet. Therefore, we did a survey at an international university in Japan to study the knowledge and attitude of female college students towards prevention of cervical cancer, to examine the age when they start sexual activity and other related attributes that may influence the risk of cervical cancer. We discuss the results of our survey and what they imply for the possible impact of an HPV immunization plan on the risk of cervical cancer in Japan, and conclude by an emphasis on the need to increase awareness among Japanese female adolescents and to enhance the cervical screening rates among older females who are already sexually active. 相似文献
