FROM HIPPOCRATIC DATABASES TO SECURE TROPOS: A COMPUTER-AIDED RE-ENGINEERING APPROACH
Authors: MASSACCI FABIO , MYLOPOULOS JOHN , ZANNONE NICOLA 
Published: May 2007

Privacy protection is a growing concern in the marketplace. Yet, privacy requirements and mechanisms are usually retro-fitted into a pre-existing design which may not be able to accommodate them due to potential conflicts with functional requirements. We propose a procedure for automatically extracting privacy requirements from databases supporting access control mechanisms for personal data (hereafter Hippocratic databases) and representing them in the Secure Tropos framework where tools are available for checking the correctness and consistency of privacy requirements. The procedure is illustrated with a case study.
Hair Relaxers Not Associated with Breast Cancer Risk: Evidence from the Black Women's Health Study
Authors: Rosenberg Lynn , Boggs Deborah A. , Adams-Campbell Lucile L. , Palmer Julie R. 
Published: May 2007

Abstract
Hair relaxers (straighteners) have been used by millions of African American women, often for many years. Relaxer ingredients can enter the body through scalp lesions and burns. Because manufacturers are not required to list all ingredients, these products may contain unknown harmful substances. We assessed hair relaxer use in relation to breast cancer incidence in the Black Women's Health Study, a nationwide follow-up study of African American women. Information on hair relaxer use was collected in 1997; 48,167 women were followed subsequently through 2003 for incident breast cancer. Incidence rate ratios of breast cancer were estimated with Cox regression. During 266,298 person-years of follow-up, 574 incident cases of breast cancer were ascertained. There were no increases in breast cancer risk associated with any categories of duration of hair relaxer use, frequency of use, age at first use, number of burns experienced during use, or type of relaxer used. The incidence rate ratio for use at least seven times a year for 20 or more years relative to use for less than a year was 0.98 (95% confidence interval, 0.78-1.39). These results suggest that hair relaxer use does not increase the incidence of breast cancer in African American women. (Cancer Epidemiol Biomarkers Prev 2007;16(5):1035–7)
Validity and Reliability of the Movement Ability Measure: A Self-Report Instrument Proposed for Assessing Movement Across Diagnoses and Ability Levels
Authors: Allen Diane D 
Published: May 2007

Background and Purpose
Physical therapists lack instruments that assess movement across diagnoses and ability levels while focusing on physical therapy–specific outcomes. This article describes the creation of a Movement Ability Measure (MAM) and initial evidence of validity and reliability.

Subjects
More than 300 adult volunteers with various movement levels completed the 24-item questionnaire.

Methods
Item response theory methods were used to create the MAM and gather evidence of content and construct validity, test-retest and other types of reliability, and concurrent validity with the California Functional Evaluation instrument and self-acknowledgement of movement problems.

Results
The intraclass correlation coefficient for test-retest reliability was .92. Person separation reliability was .98. Correlation (r) with the California Functional Evaluation instrument was .76. Respondents who denied having movement problems perceived a significantly higher level of movement ability than those who claimed to have a little, some, or a lot of movement problems in the preceding week.

Discussion and Conclusion
The MAM shows promise for documenting perceived movement ability across ability levels and diagnoses.
Associations of osseous abnormalities in Neurofibromatosis 1
Authors: Alwan S. , Armstrong L. , Joe H. , Birch P.H. , Szudek J. , Friedman J.M. 
Published: May 2007

AbstractThe characteristic sites of Neurofibromatosis 1‐associated osseous manifestations are the long bones (usually the tibia and fibula), vertebrae and sphenoid wing. Although these focal bony lesions may cause profound clinical consequences, a minority of people with NF1 are affected. However, most people with NF1 are shorter than expected for their age, gender and family. The pathogenesis of NF1 focal osteopathy and its relationship, if any, to short stature are unknown. We examined associations between the occurrence of various osseous lesions in 3377 NF1 probands from the Children's Tumor Foundation NF International Database. Using logistic regression analysis among 260 NF1 probands who had undergone radiological examination of both the spine and skull, we found associations between the occurrence of sphenoid wing and long bone osteopathy (conditional odds ratio [OR] = 6.1; 95% confidence interval [CI] = 1.7–22.3; P = 0.006) and between sphenoid wing and vertebral osteopathy (OR = 16.9; 95% CI = 5.3–53.3; P < 0.001) after adjusting for age and gender. Similar findings were observed from all 3377 NF1 probands using a multivariate probit regression model. In a separate analysis, we found lower age‐ and gender‐standardized height in patients who had characteristic vertebral or sphenoid wing lesions than in people who did not (P < 0.05). We found no relationship between height and tibial osteopathy. We conclude that some people with NF1 are more likely to develop osseous manifestations than others and speculate that there may be a common pathogenetic mechanism responsible for the development of osseous abnormalities and that of the vertebrae and long bones. © 2007 Wiley‐Liss, Inc.
Morphology and properties of nanocomposites from organoclays with reduced cation exchange capacity
Authors: Chavarria F. , Nairn K. , White P. , Hill A. J. , Hunter D. L. , Paul D. R. 
Published: May 2007

AbstractOrganoclays with different levels of reduction in the original cation exchange capacity (CEC) were prepared to characterize the morphology and Young's modulus of their melt‐processed nanocomposites made from nylon 6 (PA‐6) and polypropylene/polypropylene grafted with maleic anhydride (PP/PP‐g‐MA). Wide‐angle X‐ray scattering (WAXS), transmission electron microscopy (TEM), and Young's modulus data are reported. Three different levels of CEC reduction were obtained; WAXS analysis and percentage loss on ignition (LOI) calculations for these organoclays showed a reduction in both the intergallery spacing and in the amount of organic modifier contained in the clay with CEC reduction. The morphology and modulus results show that these reduced‐CEC organoclays led to lower exfoliation and modulus enhancement for both PA‐6 and PP/PP‐g‐MA nanocomposites. The results may be influenced by differences in layer charge and charge distribution that could have been produced during the charge reduction process. © 2007 Wiley Periodicals, Inc.

Emission spectroscopic analysis of poly(3‐octyl thiophene) exposed to plasmas
Authors: Rodríguez‐Lazcano Y. , Martínez H. 
Published: May 2007

AbstractEmission spectroscopy was employed to study reaction process of poly(3‐octyl thiophene) (P3OT) exposed to helium, nitrogen, air and hydrogen plasmas. The plasma was generated by an AC discharge at a pressure of 2 × 10−2 Pa. The discharge power was maintained at an output of 220 V and a current of 0.2 A. The light emitted was monitored in the case of each plasma. Measurements at various discharge times were made of several emission peaks. The dominant emission bands were assigned to CH2 at 589.32 nm, S2 (B3Σu−–X3Σg−) at 413.35 nm, CH+ (A1Π–X1Σ) at 422.51 nm and C3H3 at 344.02 nm. These dominant emission bands indicate that the poly(3‐octyl thiophene) was decomposed by plasma interaction. Nevertheless, the reaction between the polymer and nitrogen, hydrogen and air plasmas is more intense than that in the helium plasma. The possible reaction channels and formation mechanisms of some species produced are discussed. © 2007 Wiley Periodicals, Inc. J Appl Polym Sci 2007
Surface‐modifiers of clay on mechanical properties of rigid polyurethane foams/organoclay nanocomposites
Authors: Xu Zhongbin , Tang Xiling , Gu Aijuan , Fang Zhengping , Tong Lifang 
Published: May 2007

AbstractThree different surface modifiers, octadecyl trimethyl ammonium (ODTMA), octadecyl primary ammonium (ODPA), and decanediamine (DDA) were used to modify Na+ montmorillonite (MMT), and the resultant organoclays were coded as ODTMA‐MMT, ODPA‐MMT, DDA‐MMT, respectively. Rigid PU foams/organoclay composites were prepared by directly using organoclay as the blowing agent without the addition of water. Investigation shows that the morphology of the nanocomposites is greatly dependent on the surface modifiers of clay used in the composites. In detail, DDA‐MMT is partially exfoliated in the PU matrix with the smallest cell size, while two others are intercalated in the PU matrices with smaller cell sizes. The sequence of their cell sizes is pristine PU foams > rigid PU foams/ODTMA‐MMT > rigid PU foams/ODPA‐MMT > rigid PU foams/DDA‐MMT, and the average cell size of rigid PU foams/DDA‐MMT composites decreases evidently from 0.30 to 0.07 mm. Moreover, all rigid PU foams/organoclay composites show remarkable enhanced compressive and tensile strengths as well as dynamic properties than those of PU foams, and the enhancement degree coincides well with the relative extent of internal hydrogen bonding of materials and gallery spacing of organoclay. For example, in the case of rigid PU foams/DDA‐MMT composite, 214% increase in compressive strength and 148% increase in tensile strength compared with those of pure PU foams were observed. © 2007 Wiley Periodicals, Inc.

Mutational activation of ErbB family receptor tyrosine kinases: insights into mechanisms of signal transduction and tumorigenesis
Authors: Riese David J. , Gallo Richard M. , Settleman Jeffrey 
Published: May 2007

AbstractSignaling by the Epidermal Growth Factor Receptor (EGFR) and related ErbB family receptor tyrosine kinases can be deregulated in human malignancies as the result of mutations in the genes that encode these receptors. The recent identification of EGFR mutations that correlate with sensitivity and resistance to EGFR tyrosine kinase inhibitors in lung and colon tumors has renewed interest in such activating mutations. Here we review current models for ligand stimulation of receptor dimerization and for activation of receptor signaling by receptor dimerization. In the context of these models, we discuss ErbB receptor mutations that affect ligand binding and those that cause constitutive receptor phosphorylation and signaling as a result of constitutive receptor dimerization. We discuss mutations in the cytoplasmic regions that affect enzymatic activity, substrate specificity and coupling to effectors and downstream signaling pathways. Finally, we discuss how emergent mechanisms of ErbB receptor mutational activation could impact the search for clinically relevant ErbB receptor mutations.

Pyramidal inversion mechanism of simple chiral and achiral sulfoxides: A theoretical study
Authors: Marom Hili , Biedermann P. Ulrich , Agranat Israel 
Published: May 2007

AbstractThe pyramidal inversion mechanism of simple sulfoxides was studied, employing ab initio and DFT methods. The convergence of the geometrical and energetic parameters of H2SO and DMSO with respect to the Hamiltonian and basis set was analyzed in order to determine a computational level suitable for methyl phenyl sulfoxide (3), methyl 4‐cyanophenyl sulfoxide (4), diphenyl sulfoxide (5), 4,4′‐dicyanodiphenyl sulfoxide (6), benzyl methyl sulfoxide (7) and benzyl phenyl sulfoxide (8). The DFT B3LYP/6‐311G(d,p) level was chosen for further calculations of larger sulfoxides. The barriers ΔE‡ calculated for the pyramidal inversion mechanism of sulfoxides 3–8 are in the range of 38.7–47.1 kcal/mol. These values are in good agreement with the experimental barriers for racemization via the pyramidal inversion mechanism. A resonance effect of a phenyl ring selectively stabilizes the transition state conformations, decreasing the energy barrier for pyramidal inversion by about 3 kcal/mol, compared to a similar molecule without a phenyl substituent. Introducing electron withdrawing groups (cyano) at the para positions of the phenyl ring(s) causes a further decrease of the energy barrier. Chirality, 2007. © 2007 Wiley‐Liss, Inc.
