Prostate Specific Antigen (PSA) has emerged as the most applicable and important tumor marker for carcinoma prostate. In the
present study PSA was determined in serum of healthy subjects, patients of benign prostate hypertrophy (BPH) and Carcinoma
Prostate (Ca−P) to evaluate its diagnostic efficiency in day to day management of prostate cancer patients and in differentiating
patients of early prostate cancer from those with BPH. Receiver operating characteristic curve (ROC) revealed 2 ng/ml and
10 ng/ml cut off serum PSA level for BPH and untreated carcinoma prostate patients (Ca−P). An extremely significant increase
(P<0.0001) was observed in mean PSA concentration in BPH patients and adenocarcinoma prostate patients when compared to healthy
males. Clinical relevance of PSA was highlighted by a case study of cancer patient prior to any therapy till death. 相似文献

自20世纪80年代中期以来,全世界范围内接连出现的政府主导的改革将高等教育系统向"教科书般"经济市场越推越近已实施的改革包括公司化、引入竞争性资助、增加学费和其他费用、使用高校管理中产出模式和绩效报告。但是,没有一个国家面向本国学生的第一学位教育是按照真正的资本主义经济市场来运作的,没有研究型大学的发展是被股东、利润、市场份额、配置效率或商品形式所驱动的。在一些国家,只有职业培训和国际教育才会真正收取商业性质的学费。虽然高等教育中普遍存在激烈的竞争、企业家精神和消费者话语,但资本主义在其中没有一席之地;现有的高等教育市场充其量是一个受监管的准市场在许多国家,高等教育领域的"市场改革"不同于交通、通信、广播电视和医疗保险界的私有化和商业化。究其原因,本文发现真正的市场改革受制于高等教育领域特定的内在限度(公共产品、地位竞争)以及与这些限度相关的政治因素、高等教育市场改革计划在本质上是乌托邦式的,目前市场改革的抽象理想仍在持续并不是因为它具有真正实现的前景,而是由于外源性政策的推动(如财政缩减、政府控制等)。如果资本主义市场是无法实现的,为什么要继续假装它们可以实现呢?我们需要一个与教育系... 更多还原 相似文献

Against the background of vast changes in doctoral education and the emergence of non-traditional doctoral programmes, this paper investigates the habitus of non-traditional PhD students at a South African university. Bourdieu's conceptual tool of habitus informed the study. In-depth and open-ended interviews were conducted with 10 non-traditional students. Data analysis indicates non-traditional students' complex and multifaceted habitus. Non-traditional PhD students' dispositions and experiences include tenacious self-motivation and self-regulation in the face of severely constraining conditions, diverse epistemologies, hybrid goals, more communal orientations, perplexedness about ‘produce new knowledge’ and other requirements of the PhD, vulnerability regarding funds, complex self-change ranging from elation and affirmation to humiliation and confusion and exclusion and non-recognition at the department and faculty levels. These findings indicate greater challenges for non-traditional doctoral programmes that would respond to the academic and social needs of non-traditional students. 相似文献

Abstract An OPI approach (Naidoo and Rolls, 2000) was used to understand how small-scale cattle keepers in a village in Mauritius managed information content. Grounded theory emerged from the study to show that management of information is basically an interaction between working knowledge and information from sources influenced by personal characteristics. The cattle keepers manage information through nine structures of information at the cognitive level. The OPI method has implications for future extension work. 相似文献

The article examines the theoretical and empirical literature on higher education’s role in relation to social equity and
related notions of citizenship, social justice, social cohesion and meritocracy. It considers both the education and the research
functions of higher education and how these impact upon different sections of society, on who benefits and who loses from
them. Questions for future research on the wider impact of higher education are posed as well as some research questions on
the narrower issue of widening participation. 相似文献

Humoral immune response against PPD derived A60 antigen was evaluated by quantification of serum A60 antibodies in thrity healthy adults not exposed to tuberculosis (Group 1), in twenty seven healthy adults exposed to tuberculosis patients i.e. staff working in wards of tuberculosis hospital for one to thirty years (group 2), in twenty five pulmonary tuberculosis patients admitted to the Institute for Chest Diseases, Hyderabad (Group 3) and in sixty neurotuberculosis patients admitted to Neurosurgery department of our institute (Group 4). Highly significant elevation of A60 antibodies was observed in pulmonary tuberculosis patients (p<0.01) compared to healthy adult groups. A significant elevation in serum was also observed in case of neurotuberculosis group compared to both healthy groups (p<0.01). A test on A60 antibodies in serum gavv a sensitivity of 100%, specificity of 96.6%, positive predictive value of 81% and negative predictive value of 100% for pulmonary tuberculosis, whereas a sensitivity of 58%, positive predictive value of 79% and negative predictive value of 75% were noted for neurotuberculosis patients. Results of A60 antibodies in ten cerebrospinal fluids (CSF) obtained from non tuberculosis patients and thirty two CSF from patients of neurotuberculosis did not show significant elevation of antibodies. However the ninetyfive percentile value of CSF A60 antibodies was higher in neurotuberculosis (7.4 U/ml) group compared to nontuberculous group (3.8 U/ml) and the test showed a good positive predictive value (83%), very low negative predictive value (25%) and low sensitivity (63%). Serum A60 antibody assay appears to be a good serological marker available today for pulmonary tuberculosis and a supportive marker for neurotuberculosis. 相似文献

Ovarian cancer is the fifth leading cause of death in women. The incidence of this malignancy increases in women over the
age of 40. The overall five years survival is less than 30%, as most women present with advanced stage disease. Until recently,
detection of early stage ovarian cancer has been difficult since it is usually nonpalpable and asymptomatic. The definitive
diagnosis of an ovarian mass is a common problem in gynecologic patients with adnexal mass. The routine standard evaluation
for adnexal masses includes patient's history, physical examination, ultrasound and histopathological examination. These parameters
individually or in combination have little predictive value. The accuracy of diagnostic tools are of immense value and great
concern to practicsing Gynecologists and Oncologists. The clinical application of serum concentration of CA 125, AFP and hCG
is of great help not only as diagnostic aid but also in monitoring efficacy of any treatment modality like chemotherapy, radiotherapy
or surgical resection. Additionally, evaluation of tumor marker concentration helps in predicting early biochemical recurrence
and in prognostication in different types of ovarian malignancies. The ability to differentiate a malignant mass from a benign
pelvic mass pretherapeutically could be enhanced optimally by additional use of tumor markers such as cancer antigen CA-125,
alphafetoprotein and human chorionic gonadotrophin in pre-and postmenopausal women. 相似文献

Reflecting on the training programmes for school counsellors, I feel that there is a need for more adequate training in competences and skills in basic counselling and human relationships. There is a strong need for a more balanced approach between theory and practical application. This article examines microcounselling as an innovation in interviewing training for school counsellors in particular. 相似文献

The centrality of service learning in the development of students’ professional practice has received worldwide attention. Exposure to appropriately designed service learning experience determines the acquisition of graduate attributes. This article addresses a study in which the key question was: What methods and strategies do students and their clinical supervisors find beneficial in improving their learning experiences during service learning placements? Drawing on the views and experiences of a group of final year occupational therapy (OT) students and their supervisors, the initial focus is on concepts in learning relevant to service learning and professional development, including Vygotsky's zone of proximal development (ZPD), the capability approach and collaborative and peer assisted learning. This is followed by an overview of the methodology and an analysis of the students’ and clinical supervisors’ experiences during service learning. The discussion focuses on the implications of the study findings for practice within a service learning context to enhance the alignment of institutional practices with students’ needs. 相似文献
