This pilot study constitutes the first exploration of the impact of breast cancer on Asian American women. Three hypotheses guided this study: (1) Asian American women would choose breast conserving therapy and breast reconstruction at a lower rate than the Anglo American women due to cultural differences in body image, (2) Asian American women with breast cancer would express psychological distress somatically and Anglo American women would express distress emotionally, and acculturation levels of the Asian American women would modify the expressions of distress such that women with high acculturation will express distress more emotionally and less acculturated women would express distress more somatically, and (3) Asian American women would seek assistance for psychosocial problems at a significantly lower rate than Anglo women. Ethnicity, age, and levels of acculturation were found to be significant variables that had to be considered simultaneously. The three hypotheses were only partially supported: (1) Asian American women chose breast conserving therapy and adjuvant therapy at a significantly lower rate than the Anglo American women, (2) Contrary to the hypothesis, somatization did not appear to be a dominant form of symptom presentation for Asian American women regardless of level of acculturation, and (3) Asian American women sought professional assistance for psychosocial problems at a significantly lower rate than Anglo women. Asian American women reported using different modes of help-seeking behavior for emotional concerns and receiving different sources of social support than the Anglo American women. Cultural interpretations of the findings are offered to explain the differences in the physical, emotional, and social responses to the breast cancer experience of Asian American women compared with the Anglo Americans, and notably between the Chinese- and Japanese Americans as well. The findings of this study warrant more refined exploration in order to improve the medical, psychological and social outcomes for Asian American women with breast cancer. 相似文献

A hydrodynamic numerical model and a tide-surge interaction model are described for the evaluation of storm surges and their
interaction with the tides in the Bay of Bengal. Numerical experiments are performed with the help of these models to simulate
the surges generated by three recent severe cyclonic storms which struck the east coast of India and Bangladesh. The predicted
peak sea-surface elevations compare well with the limited observed values. 相似文献

Classification of underground pipe scanned images using featureextraction and neuro-fuzzy algorithm 总被引:1,自引:0,他引:1
Pipeline surface defects such as holes and cracks cause major problems for utility managers, particularly when the pipeline is buried under the ground. Manual inspection for surface defects in the pipeline has a number of drawbacks, including subjectivity, varying standards, and high costs. Automatic inspection system using image processing and artificial intelligence techniques can overcome many of these disadvantages and offer utility managers an opportunity to significantly improve quality and reduce costs. A recognition and classification of pipe cracks using images analysis and neuro-fuzzy algorithm is proposed. In the preprocessing step the scanned images of pipe are analyzed and crack features are extracted. In the classification step the neuro-fuzzy algorithm is developed that employs a fuzzy membership function and error backpropagation algorithm. The idea behind the proposed approach is that the fuzzy membership function will absorb variation of feature values and the backpropagation network, with its learning ability, will show good classification efficiency. 相似文献

The glnA gene from the human pathogen Streptococcus agalactiae was cloned from a genomic library prepared with the lambda phage vector lambdaDASHII. A 4.6-kb DNA fragment of one of the recombinant phages was subcloned in pUC18. This Escherichia coli clone expressed a 52-kDa protein encoded by a 1,341-bp open reading frame. The nucleotide sequence of the open reading frame and the deduced amino acid sequence shared a significant degree of homology with the sequences of other glutamine synthetases (GS). The highest homology was between our deduced protein and GS of gram-positive bacteria such as Bacillus subtilis, Bacillus cereus, and Staphylococcus aureus. Plasmids with the cloned streptococcal glnA were able to complement E. coli glnA mutants grown on minimal media. Rabbit antisera to streptococcal GS recombinant protein recognized not only the recombinant protein but also a similar-sized band in mutanolysin extracts of all group B streptococcal strains tested, regardless of polysaccharide type or surface protein profile. The amino acid sequence of the deduced protein had similarities to other streptococcal cell-surface-bound proteins. The possible functional role of the immunological features of streptococcal GS is discussed. 相似文献

Temporal expression of PTHrP during endochondral bone formation in mouse and intramembranous bone formation in an in vivo rabbit model 总被引:1,自引:0,他引:1

Expression of parathyroid hormone-related protein (PTHrP) messenger RNA (mRNA) and protein was investigated throughout the developmental progression of endochondral bone formation in mouse and intramembranous bone formation in an in vivo model in rabbit, using in situ hybridization and immunohistochemistry. Endochondral bone formation was investigated in a developing embryo, newborn, and adult mouse. In fetal long bones through to newborn (day 7), PTHrP mRNA and protein were consistently expressed in chondrocytes within the proliferative, transitional, and hypertrophic zones. In addition, high levels of PTHrP were also detected in osteoblasts on the surface of trabecular bone surfaces. Similarly, at the adult stage (week 7), PTHrP mRNA and protein were consistently expressed in chondrocytes at epiphyseal ends of the subarticular cartilage, within cortical periosteum, as well as in osteoblasts located at the metaphyseal trabecular bone surfaces. Using an in vivo intramembranous bone formation model in rabbits, expression of PTHrP mRNA and protein was demonstrated in preosteoblasts prior to trabecular bone formation (1-week bone harvest). As bone formed (2-, 3-, and 4-week bone tissue harvests), PTHrP mRNA and protein were highly expressed in actively synthesizing osteoblasts and in those osteocytes embedded within the superficial layers of the bone matrix. Lining osteoblasts and osteocytes buried deeply in the bone matrix displayed weak or no signal for PTHrP. The pattern of spatial and temporal expression of PTHrP demonstrated in cartilage cells and osteoblasts in the two systems suggests an important role of PTHrP in both endochondral and intramembranous bone formation. 相似文献
