    Notes: The structural stability and electronic properties of a (Sb2)2/(GaSb)2(111) semimetal–semiconductor superlattice are investigated by a first-principles all-electron linearized augmented plane-wave method within the local spin density functional approximation. When bulk values are used the two interfacial distances D1 and D2 are energetically unfavorable. The fully optimized structure shows that the bond lengths of Sb–Ga and Sb–Sb at interfaces are 1.3% and 2.8% longer than their bulk values, respectively. Further electronic band calculations of the stable (Sb2)2/(GaSb)2(111) superlattice show that the system has semimetallic behavior. A p-like interface band is observed below the Fermi level. © 1998 American Institute of Physics.

    Notes: Determinants of parental decisions on ‘drop out’ from cancer treatment for childhood cancer patients Little is known about the psychosocial process of parental decisions on ‘drop out’ from cancer treatment for paediatric patients in Taiwan. This study, based on structured in-depth interviews, attempted to document the determinants of parental decisions on drop out. A total of 19 parents of paediatric cancer patients who dropped out from a cancer treatment for at least a month within 3 years since first treatment were interviewed. Content analysis of qualitative data revealed six categories of determinants associated with parental decisions: suffering severe pain from medical treatments and adverse side-effects; desire for better and less painful treatments; adverse effect of other patients’ experiences; searching for possible explanations for disease after prolonged denial of diagnosis; lack of empathy from health care professionals; and misinterpretation of improved prognostics. These findings reflected the deficiency of psychological and emotional support for parents from health care professionals prior to and during cancer treatment.

    Genome-based analysis of virulence genes in a non-biofilm-forming Staphylococcus epidermidis strain (ATCC 12228) (2003)

    Notes: Staphylococcus epidermidis strains are diverse in their pathogenicity; some are invasive and cause serious nosocomial infections, whereas others are non-pathogenic commensal organisms. To analyse the implications of different virulence factors in Staphylococcus epidermidis infections, the complete genome of Staphylococcus epidermidis strain ATCC 12228, a non-biofilm forming, non-infection associated strain used for detection of residual antibiotics in food products, was sequenced. This strain showed low virulence by mouse and rat experimental infections. The genome consists of a single 2499 279 bp chromosome and six plasmids. The chromosomal G + C content is 32.1% and 2419 protein coding sequences (CDS) are predicted, among which 230 are putative novel genes. Compared to the virulence factors in Staphylococcus aureus, aside from δ-haemolysin and β-haemolysin, other toxin genes were not found. In contrast, the majority of adhesin genes are intact in ATCC 12228. Most strikingly, the ica operon coding for the enzymes synthesizing interbacterial cellular polysaccharide is missing in ATCC 12228 and rearrangements of adjacent genes are shown. No mec genes, IS256, IS257, were found in ATCC 12228. It is suggested that the absence of the ica operon is a genetic marker in commensal Staphylococcus epidermidis strains which are less likely to become invasive.

    Notes: A study of 20 mothers was conducted to determine the cognitive operations used by Chinese mothers in conceptual behaviour toward their newborn infants. Mothers' spontaneous speech, referring to the newborn infants during the feeding sessions, comprised the data for analysis. A total of 2300 records of behaviour were produced as mothers used orienting, evaluating and delineating operations in conceptualizing their newborn infants. Four aspects of the newborn infant namely, appearance, physical state, body function and social characteristics were important to these new mothers. Mothers tended to use orienting behaviour more frequently (P 〈 0.001) than both evaluating and delineating behaviours as they conceptualized irfants' body functions and physical state. Delineating behaviour was significantly (P 〈 0.001) more important in relation to infants' appearance than to other aspects of the infants. Mothers' parity seemed to be a significant variable (P 〈 0.05) only when mothers evaluate the infants' appearance. Comparison between Chinese and American maternal conceptual behaviour revealed that American mothers, in general, tended to use evaluating and delineating behaviour more frequently than Chinese mothers; but no significant difference in using orienting behaviour was found. As for the four aspects of the infant, there was no significant difference in two groups as they conceptualized infants' appearance and social characteristics. However, a significant difference (P 〈 0.05) was found in relation to infants' physical state and body functions.

    Notes: Aims.  This paper reports on a study carried out to establish a decision tree model to describe how women in Taiwan make the decision whether or not to have a hysterectomy. In addition, we examined the predictability of the decision-tree model.Background.  Hysterectomy is the second most common surgical procedure performed worldwide. Medical professionals believe that the operation can relieve pain and prevent cervical cancer, thus improving a woman's quality of life. While most physicians advise hysterectomy even for benign uterine conditions, feminists decry the belief that the uterus has no purpose, believing that it is an important symbol of womanhood.Methods.  The study was conducted in two phases. Phase I, the model development phase, was carried out to generalize data from a qualitative study of 14 women and to establish a tree model outlining their decision to proceed with hysterectomy. The second phase was the model prediction phase that applied inductive and deductive methods to data analysis and development of the decision-tree model. The model tree was then tested with 18 women who were deciding whether or not to undergo hysterectomy. Using the decision-making tree, we studied the women's thought processes and analysed their primary concerns. The study was carried out in 1999–2001.Results.  The study determined 13 criteria that Taiwanese women use when deciding about having a hysterectomy. Developed in accordance with Gladwin's methodology, the model tree successfully predicted 90% of decisions whether or not to have a hysterectomy.Conclusions.  Nurses working in gynaecological services should understand how women decide to undergo hysterectomy so that the proper counselling and follow-up can be provided. With further testing, our decision tree may help in this process.

    Notes: Objective: To explore factors influencing breast cancer screening behavior among Chinese women residing in the United States. Design: A descriptive study guided by the health belief model adapted for Chinese American women. An English-language questionnaire was modified, translated, and pretested before use in the study sample. Data were analyzed using descriptive and multivariate analysis techniques. Setting: An urban area in Michigan in 2001. Participants: A consecutive nonprobability sample of 206 Chinese American women age 40 and older. Main Outcome Measure: The percentage of women age 40 and older who received a mammogram in the past year. Results: Access to health care, perceived barriers to mammography screening, need for breast health care, and information-seeking behavior had direct effects on Chinese American women's mammography screening utilization. Cultural affiliation had an indirect effect on breast cancer screening behavior, moderated through access to health care. The variance in mammography screening explained by these factors was 51%. Conclusion: Effective strategies for promoting breast cancer screening among Chinese American women should address ways to improve information-seeking behaviors and access to health care. Cultural affiliation and beliefs should be considered when counseling Chinese American women regarding breast cancer screening.

    Notes: A protease (protease A) was successfully purified from the extracellular proteins of Vibrio parahaemolyticus no. 93, a clinical strain carrying neither tdh nor trh genes, using phenyl-Sepharose CL-4B hydrophobic interaction chromatography. The molecular mass of protease A was 43 kDa using gel filtration, which was in agreement with the results obtained from SDS–PAGE, suggesting that protease A was a monomeric protein. Additionally, the isoelectric point of this protein was 5.0. The optimum temperature and pH of protease A ranged from 40°C to 50°C and pH 8, respectively. Protease A activity was inhibited by serine protease inhibitors, such as phenylmethylsulfonyl fluoride and soybean trypsin inhibitor; moreover, the activity could be blocked by treatment with 20 mM of 1,10-phenanthroline, but could not be restored by adding metal ions. These results indicated that protease A is a serine protease that requires metal. The 12 N-terminal residues of protease A showed a high degree of identity (81%) to the sequence of Vibrio metschnikovii VapT serine protease. The purified protease had significant effects on the growth of Chinese hamster ovary, HeLa, Vero and Caco-2 cells and its cytotoxic activity was not blocked by gangliosides. Protease A lysed erythrocytes well but its hemolytic activity was unstable after heat treatment, indicating that protease A is able to cause hemolysis but is a heat-labile protein. The purified protease caused tissue hemorrhage and death in mice when injected both intraperitoneally and intravenously. In conclusion, this is the first report of a serine protease purified directly from the supernatant of V. parahaemolyticus and identifying it as a potential virulence factor.
