Oral Cancer is one of the five leading sites of cancer in Indian population. The circulating immune complexes were investigated in 100 serum samples of 60 oral cancer patients having different grades of the disease and 40 patients with precancerous lesions obtained from Nair Hospital Dental collage, Mumbai. The results obtained were compared with those of group of 40 healthy blood donors. Elevated levels of Circulating Immune Complexes were observed in oral cancer patients and patients with oral precancerous lesions. 92% positive samples were observed in well differentiated squamous cell carcinoma whereas 100% positive samples were observed in both moderately and poorly differentiated squamous cell carcinoma. Oral leukoplakia and oral submucous fibrosis showed 15% and 90% positivity respectively. Increased level of Circulating Immune complexes in high grade tumor suggest that Circulating Immune complexes is likely to contribute in evaluating the degree of malignancy, but follow up study is needed to draw any conclusion regarding it's prognostic role  相似文献

This study examined the effects of social influences in the lives of an ethnically diverse sample of fifth through eighth grade students with and without learning disabilities (LD) using survey data and academic achievement scores collected in 19 Chicago public schools from 1993–1997. Similarities and differences in student perceptions of school, family, and peer group contexts were examined. In addition, longitudinal data were analyzed using hierarchical linear modeling (HLM) to identify contextual influences on changes in student reading achievement over time. Comparisons of student responses confirm and extend existing findings in the literature concerning the perceptions of students with LD of their social environments. In particular, having a learning disability was associated with consistent, mostly negative, effects on social relations across the contexts of students’ lives, regardless of gender, race, grade, and socioeconomic status. In addition, student perceptions of their friendship groups were found to have small, but significant, effects on their growth in reading achievement over the course of middle school. While students with and without LD had somewhat different views of their social contexts, the processes working within these environments appeared to affect their reading achievement in similar ways. The results suggest that careful attention should be paid to the social contexts of students’ lives when planning academic interventions.  相似文献

This article offers a case study account of a garden-themed poetry writing project run by a creative writing organisation in partnership with a class of 9–10-year-old children from a London primary school. I explore the concept of creativity which framed the five-week project and analyse the different ways in which the creative practitioner worked collaboratively with the class teacher to develop children’s writing, not least by adopting an open, inclusive pedagogy. Despite the obvious successes of this project, I raise questions about the role of creative practitioners working in schools and the ways in which special projects locate creativity on the margins of the mainstream curriculum.  相似文献

Individuals with autism spectrum disorder (ASD) show differences in face processing abilities from early in development. To examine whether these differences reflect an atypical versus delayed developmental trajectory, neural responses to familiar and unfamiliar faces in twenty-four 18- to 47-month-old children with ASD were compared with responses of thirty-two 12- to 30-month-old typically developing children. Results of 2 experiments revealed that neural responses to faces in children with ASD resembled those observed in younger typically developing children, suggesting delayed development. Electrophysiological responses to faces were also related to parent report of adaptive social behaviors for both children with ASD and typical development. Slower development of the face processing system in ASD may be related to reduced self-directed "expected" experience with faces in early development.  相似文献

A questionnaire was administered to 1,929 applicants to Oxford University, including measures of trait anxiety, behavioural response to examinations and to breakdown in relationships. 635 of these applicants were admitted to the university and of these, 383 also responded to a questionnaire administered 4 years later, just before their final examinations. The classification (first, upper and lower second, third class) and marks in the final examinations were obtained and the relationship between the personality measures and academic performance were calculated. Women showed higher anxiety scores than men at both times of testing. Women who obtained the best (first class) degrees scored significantly higher on anxiety than those who performed less well. In contrast, there was no such difference in men. Explanations for anxiety having a facilitatory effect on academic performance of women at Oxford University are proposed.  相似文献

The race to establish regional education hubs is a recent development in cross-border higher education. This article briefly examines the rationales and strategies used by three countries in the Middle East and three in South East Asia which are working towards positioning themselves as regional education hubs. The different approaches and purposes among the six countries highlight the need for a typology of education hubs. Three types are proposed: the student hub, the training and skilled workforce hub, and the knowledge/innovation hub. The final section of the paper takes a closer look at Malaysia??s cross-border education initiatives and its actions to establish itself as a competitive education hub in a region where Singapore and Hong Kong have similar intentions. Whether Malaysia has the ability to make a quantum leap from being a student hub to becoming a knowledge/innovation hub remains to be seen and appears to be an optimistic outlook.  相似文献
