This study explored the relationships between cultural values, appraisal of child behavior problems, and associated help‐seeking intentions among Chinese‐American parents. Questionnaires were administered to 120 Chinese‐American parents of elementary‐school‐aged children. Parents were asked how they might respond if their child displayed the behavioral problems depicted in a hypothetical vignette. Influences of Chinese value orientation, severity appraisal, and affective reactions on help‐seeking intentions were examined using regression analyses and structural equation modeling. The study examined three hypotheses regarding the nature of the influence of cultural value orientation on help‐seeking intentions: (a) a direct effect model, (b) an indirect effect through cultural differences in severity appraisal, and (c) an indirect effect through cultural differences in affective responding. Results supported the hypothesis that cultural value orientation exerted an indirect effect on help‐seeking intentions through its influence on affective responding. Those parents who had more traditional Chinese values responded with more feelings of shame to child behavior problems and, in turn, reported lower intentions to seek help. Findings are discussed with reference to the literature on help‐seeking among Asian Americans. © 2001 John Wiley & Sons, Inc. 相似文献

BACKGROUND: Peanut allergy is an important health problem in the United States, affecting approximately 0.6% of children. Inadvertent exposure to peanut is a risk factor for life-threatening food-induced anaphylaxis. OBJECTIVE: The purpose of this investigation was to develop an immunoassay for a major peanut allergen, Ara h 1, to detect peanut allergen in foods so that the risk of inadvertent exposure can be reduced. METHODS: A specific 2-site monoclonal antibody-based ELISA was developed to measure Ara h 1 in foods. The sensitivity of the assay was 30 ng/mL. Ara h 1 was measured in foods (n = 83) with or without peanut and in experiments to optimize allergen yield and to determine peanut contamination in spiked foods. RESULTS: Ara h 1 levels in food products ranged from less than 0.1 microg/g to 500 microg/g. Ara h 1 measured in ng/mL was transformed to microg/g for food products. Peanut butter contained the highest amounts of Ara h 1. Peanut extracts contained from 0.5 to 15 mg Ara h 1/g of peanut depending on the extraction conditions. Optimal extraction of Ara h 1 was obtained by using phosphate buffer with 1 mol/L NaCl and Tween at 60 degrees C. Ara h 1 was not always detected in presence of chocolate under the extraction conditions tested. Spiking experiments showed that the assay could detect approximately 0.1% Ara h 1 contamination of food with ground peanut. There was an excellent correlation between Ara h 1 levels and peanut content measured by using a commercial polyclonal antibody-based ELISA (r = 93, n = 31, P <.001). CONCLUSION: A new sensitive and specific monoclonal antibody-based ELISA was used to monitor Ara h 1 content in food products. This assay should be useful for monitoring peanut contamination in the food manufacturing and processing industry and in developing thresholds for sensitization or allergic reaction in persons with peanut allergy. 相似文献

OBJECTIVE: To evaluate the effect of prostaglandin E2 (PGE2) and interleukin-1beta (IL-1beta) on integrin expression. DESIGN Cultures of endometrial epithelial cells from normal endometrium. SETTING: All endometrial specimens were obtained from the Obstetrics and gynecology Department of the Catholic University, Rome, Italy. PATIENTS: Four patients were normal menstrual cycles undergoing operative laparoscopy for non-endometrial problems. INTERVENTION: Endometrial samples were collected by uterine courettings. MAIN OUTCOME MEASURE: Immunocytochemistry for beta1 and beta3 integrin subunits. RESULTS: PGE2 clearly enhances both beta1 and beta3 integrin subunit expression. IL-1beta seem to slightly increase only beta3 subunit expression. CONCLUSIONS: In light of the critical role played by eicosanoids in endometrial differentiation, we suggest that PGE2 is also involved in local paracrine regulation of integrin expression. 相似文献

Gastrointestinal mesenchymal tumors - immunophenotypic classification and survival analysis 总被引:8,自引:0,他引:8
Rudolph P Chiaravalli AM Pauser U Oschlies I Hillemanns M Gobbo M Marichal M Eusebi V Höfler H Capella C Klöppel G 《Virchows Archiv : an international journal of pathology》2002,441(3):238-248
The current definition of gastrointestinal tumors (GIST) as CD117-positive mesenchymal tumors of uncertain malignant potential fails to include a number of cases with similar histology. In an attempt to improve the classification of these neoplasms, we conducted an immunohistochemical analysis of 244 mesenchymal tumors with histological features of GIST. According to their immunophenotype, the tumors were classified as GISTs, which are characterized by CD117 (c-kit) expression; gastrointestinal CD117-negative CD34 positive stromal tumors (GINST); alpha-smooth muscle actin and/or desmin positive gastrointestinal leiomyogenic tumors (GILT); S-100 and glial fibrillary acidic protein positive gastrointestinal glial/schwannian tumors (GIGT); gastrointestinal neuronal/glial tumors (GINT), which are positive for S-100/glial fibrillary acidic protein plus neuronal/glial markers; and gastrointestinal fibrous tumors (GIFT), which are only vimentin positive. The most common type of tumors were GIST, followed in order of frequency by GINST, GILT, GIGT, GIFT, and GINT. GISTs did not show any preferential location, whereas GINSTs occurred almost exclusively in the stomach and duodenum, and GILTs preferentially in the large intestine. Over a median follow-up period of 71 months, malignant behavior, i.e., metastatic spread, was observed in all tumor types except GINTs. Malignancy was associated with distal gut location, high mitotic activity, large tumor size, and nuclear pleomorphism, though none of these criteria alone discriminated between benign and malignant. Kaplan-Meier analysis of disease-specific survival showed significant differences in the long-term outcome of the newly defined subgroups. We conclude that, despite strong morphological similarities, gastrointestinal mesenchymal tumors are heterogeneous in their immunophenotype and biology. 相似文献

ABSTRACT This study examined if children (Mage = 14.60) with Mild Intellectual Disabilities (MID) display weaknesses in number processing and verbal working memory. An age-matched and mental age-matched (MA, Mage = 6.17) design extended by a group of 9–10-year-olds, and a group of 11–12-year-olds were used. The MID children’s working memory was equal to the MA group but poorer than the other groups. On number tasks, the MID group was faster than the MA group but slower than the other groups. All groups obtained equal Weber fraction scores and distance effects on the number comparison tasks. The MID group performed subitizing and counting faster than the MA group, but slower than the 11–12-year-olds. The results demonstrate that number processing and working memory in children with MID is characterized by a developmental delay, not a deficit. Their main problem is to access the quantitative meaning of Arabic numerals. The development of different types of cognitive abilities is differently affected by educational experience and intellectual ability. The innate number system appears to be unaffected by intellectual capacity or educational experience, while the innate working memory ability is affected by intellectual capacity but not by educational experience. Culturally acquired symbolic number abilities are strongly affected by educational experience. 相似文献

A dysmorphic patient was shown to carry a small supernumerary marker chromosome. Multicolor, centromere-multicolor and regular FISH experiments proved the marker to be an analphoid 12pter derived isochromosome. Microdissection of the marker followed by reverse painting and array CGH analysis showed that the isochromosome contains approximately 6 Mb of 12pter-12p13.31 derived sequence. This is only the second report of a marker with a neocentromere 12pter and the molecular fine mapping of the duplicated region further refines the 12p region defining the Pallister-Killian syndrome phenotype. In addition, we show the feasibility of using microdissected chromosomes or chromosomal fragments to molecularly map the chromosomal breakpoints on array CGH. This technology may aid in the identification of chromosomal translocation breakpoints. 相似文献

Four patients with alpha-1 antitrypsin (alpha-1 AT) deficiency are presented: one woman with severe (phenotype PiZ) and 3 men with moderate (phenotype PiMZ) deficiency of alpha-1 AT. The variability of clinical presentation of hereditary emphysema is described. In all patients tobacco smoking history, spirometric and 6-minutes walking tests as well as HRCT of the lung were performed and compared. The influence of smoking on the functional status is underlined. 相似文献

In January 1999, I started a two-year course in psychodynamic counselling. One of the course requirements was to produce several work journals each term. They could be on any topic the student wished to think about or explore that pertained to the course, be it clinical or theoretical work, or professional/personal development. Three months later, I wrote one on Bion's (1962) concept of ‘the hatred of learning from experience’, after a seminar on his work. In Section 1, I present the work journal itself, in which I described my difficulties with anxiety about the course in relation to this concept: how I felt I needed to be a perfect student who ‘knew everything’; my intolerance of making mistakes; and my hatred of not knowing; in tandem with my envy of others' knowledge. In Section 2, I describe my current understanding of what I was rather desperately attempting to work out in the journal – taking into consideration both my emerging feelings, in light of my own history and state of mind, together with what I had come to understand – that the course was poorly structured and did not provide an adequately safe framework for clinical work and learning. This resulted in my decision to leave. In Section 3, I write about the arduous but ultimately rewarding process of returning to training, eventually culminating in my qualification as a psychodynamic psychotherapist. My final thoughts are presented in Section 4. 相似文献
