Introduction:
Heavy chain diseases (HCD) are neoplastic proliferations of B cells which secrete truncated immunoglobulin heavy chains without associated light chains. Being rare and probably underdiagnosed diseases the aim of this report is to show an additional case of gamma heavy chain disease in a 48 year old female patient with rheumatoid arthritis focusing on the laboratory presentation.Materials and methods:
Laboratory work-up included agarose gel electrophoresis (AGE), capillary zone electrophoresis (CZE), immunofixation and nephelometrically determined immunoglobulin and immunoglobulin subclasses of the patient’s serum. Urine samples were also subjected to immunofixation and to a SDS-PAGE with consecutive immunoblot.Results:
Nephelometrically measured elevated IgG concentrations were noted in combination with a decreased gamma globulin region and an increased beta globulin region on AGE. A definite monoclonal spike was not identified on AGE but at least suspected on CZE; finally serum and urine immunofixation demonstrated a monoclonal gamma heavy chain devoid of any corresponding light chains confirming the diagnosis of HCD. Analysis of the gamma heavy chain (HC) with means of SDS-PAGE revealed proteins of 40 kD and 80 kD most likely presenting a truncated HC in its monomeric and dimeric form and possibly leading to the failure of IgG-subclass typing with the applied IgG subclass antisera.Conclusion:
This case report illustrates a new case of gamma HCD demonstrating variable laboratory manifestations and therefore the need for heightened awareness concerning this disease when confronted with abnormal and discrepant protein profiles in routinely applied laboratory tests. 相似文献642.
Disclosure to parents and reasons for not disclosing different activities were examined in 489 Chinese, Mexican, and European American adolescents ( M = 16.37 years, SD = 0.77). With generational status controlled, Chinese American adolescents disclosed less to mothers about personal and multifaceted activities than European Americans and less about personal feelings than other youth, primarily because these acts were considered personal, not harmful, or because parents would not listen or understand. Disclosure regarding prudential behavior was lower among Mexican American than among European American adolescents, primarily due to concerns with parental disapproval. Multigroup path analyses indicated that greater closeness to parents is associated with more disclosure for all youth and activities; associations between family obligation and disclosure varied by domain and ethnicity. 相似文献

This study explores how graduate students enrolled in M.A./M.S. and Ph.D. geography programs perceive the social and academic
climate of their departments. A second objective is to understand how these students self-assess their own professional abilities,
values, and goals, and whether these self-assessments differ across demographic and institutional contexts. The survey instrument
for this research is based on data collected from graduate student focus groups and on validated constructs of academic culture
and climate from previous research. T-tests, ANOVA, and regression analyses identified significant differences among graduate students and their perceptions of
departmental climate when compared on the basis of gender, citizenship, race/ethnicity, disciplinary subfield, and institutional
type. Interview data provide additional context for analysis of the survey data. The primary areas in which we detected differences
in graduate students’ experiences were 1) diversity issues, 2) disciplinary and institutional cultures, 3) career planning
and development, 4) financial matters, and 5) quality of the learning environment. These differences result from the varying
social and academic dynamics of graduate programs, illustrating the importance of the local environment in shaping student
experiences.

This paper takes a cross‐disciplinary perspective in examining the views and practices of public engagement with research by UK academics. Using a mixed method approach consisting of a survey questionnaire and interviews, the paper identifies the range of audience groups that can potentially be engaged with by academics, and shows that some audiences are more relevant to particular disciplinary groups than others. The paper also identifies the various public engagement activities undertaken by academics and finds that some academics are using creative ways of engaging the public, such as using the services of public relations firms to help in disseminating their research in traditional media outlets, and also by using social media. Essentially, the study reveals that some academics feel the pressure of engaging particular audiences at the expense of those that are relevant to them and that, academics in the main, are opposed to the notion of mandating public engagement as part of appraisal systems. 相似文献
