Published: May 2009

AbstractIn order to study the effect of several compounds on packaging stability, different cosmetic ingredients at two concentration levels were added to a NeoPCL® (Acofarma, Terrassa, Spain) water emulsion, and the preparations packed in sachets and stored at 40°C during 3 months. After that, the packaging was subjected to a T‐peel test and headspace solid‐phase microextraction gas chromatography mass spectrometry (HS‐SPME‐GC‐MS) analysis. The HS‐SPME‐GC‐MS analyses were performed using a 75 μm carboxen polydimethylsiloxane fibre to check for the presence of the studied analytes in the inner layers. The study revealed that the presence of a phenyl and a hydroxyl group in the compound structure lead to an important loss of adhesion between packaging layers joined by an adhesive. The interaction between the cosmetic ingredient and the adhesive was proposed as the main cause of the loss of adhesion. However, extrusion‐coating packaging was more susceptible to delamination, particularly with the volatile compounds. Copyright © 2009 John Wiley & Sons, Ltd.
Regression modeling of combined data from multiple sample surveys
Authors: Li Lei , Levy Paul S. 
Published: May 2009

AbstractCombined data from multiple sample surveys are often used in population‐based epidemiologic studies. Combining data can be beneficial in that sampling errors are reduced and coverage biases are corrected. Also, it is often necessary in order to use information lacking in one survey but available in another. We propose an estimation equations method for generalized linear models from the combined data. The estimation procedures for logistic regression models and Poisson regression models are developed. An example of estimating the relative risk of death by smoking status is used as an illustration and a simulation study is performed to examine the performance of the method.

Published: May 2009

AbstractWhile the traditional model of genetic evaluation for breast cancer risk recommended face‐to‐face disclosure of genetic testing results, BRCA1/2 testing results are increasingly provided by telephone. The few existing studies on telephone genetic counseling provide conflicting results about its desirability and efficacy. The current study aimed to (1) Estimate the prevalence among genetic counselors of providing BRCA1/2 genetic test results by phone (2) Assess patient satisfaction with results delivered by telephone versus in‐person. A survey was sent to members of the Familial Cancer Risk Counseling Special Interest Group via the NSGC listserve and was completed by 107 individuals. Additionally, 137 patients who had received BRCA genetic testing results either by phone or in‐person at UNC Chapel Hill Cancer Genetics Clinic were surveyed regarding satisfaction with the mode of their BRCA1/2 results delivery. The genetic counseling survey revealed that the majority of responding counselors (92.5%) had delivered BRCA1/2 genetic test results by telephone. Patients having received results either in person or by phone reported no difference in satisfaction. Most patients chose to receive results by phone and those given a choice of delivery mode reported significantly higher satisfaction than those who did not have a choice. Those who waited less time to receive results once they knew they were ready also reported higher satisfaction. This study found supportive results for the routine provision of BRCA1/2 genetic test results by telephone. Results suggest that test results should be delivered as swiftly as possible once available and that offering patients a choice of how to receive results is desirable. These are especially important issues as genetic testing becomes more commonplace in medicine.

Published: May 2009

Abstract
Water-soluble hollow spherical magnetite (Fe3O4) nanocages (ca. 100 nm) with high saturation magnetization are prepared in a one-pot reaction by sol-gel method and subsequent annealing to synthesise the maghemite (γ-Fe2O3) nanocages with similar nanostructures. The nanocages have been investigated by powder X-ray diffraction (XRD), transmission electron microscope (TEM), high-resolution transmission electron microscope (HRTEM), and superconducting quantum interference device (SQUID). The results indicated that glutamic acid played an important role in the formation of the cage-like nanostructures.
Effect of trans8, cis10+cis9, trans11 Conjugated Linoleic Acid Mixture on Lipid Metabolism in 3T3‐L1 Cells

Published: May 2009

AbstractEvidence suggests that minor isomers of conjugated linoleic acid (CLA), such as trans8, cis10 CLA, can elicit unique biological effects of their own. In order to determine the effect of a mixture of t8, c10+c9, t11 CLA isomers on selected aspects of lipid metabolism, 3T3‐L1 preadipocytes were differentiated for 8 days in the presence of 100 μM linoleic acid (LA); t8, c10+c9, t11 CLA; t10, c12+c9, t11 CLA or purified c9, t11 CLA. Whereas supplementation with c9, t11 and t10, c12+c9, t11 CLA resulted in cellular triglyceride (TG) concentrations of 3.4 ± 0.26 and 1.3 ± 0.11 μg TG/μg protein, respectively (P < 0.05), TG accumulation following treatment with CLA mixture t8, c10+c9, t11 was significantly intermediate (2.5 ± 0.22 μg TG/μg protein, P < 0.05) between the two other CLA treatments. However, these effects were not attributable to an alteration of the Δ9 desaturation index. Adiponectin content of adipocytes treated with t8, c10+c9, t11 mixture was similar to the individual isomer c9, t11 CLA, and both the t8, c10+c9, t11 and c9, t11 CLA groups were greater (P < 0.05) than in the t10, c12+c9, t11 CLA group. Overall, these results suggest that t8, c10+c9, t11 CLA mixture affects TG accumulation in 3T3‐L1 cells differently from the c9, t11 and t10, c12 isomers. Furthermore, the reductions in TG accumulation occur without adversely affecting the adiponectin content of these cells.
Extended Field-of-View Sonography: Evaluation of the Superficial Lesions
Authors: Yerli Hasan , Eksioglu Secil Yucel 
Published: May 2009

Objective To evaluate the usefulness of extended-field-of-view 2-dimensional ultrasonography technique in superficial lesions. Methods During a 6-month period, 44 patients with superficial lesions on various parts of their bodies were evaluated with extended-field-of-view ultrasonography in addition to routine traditional 2-dimensional ultrasonography. If the diagnosis could not be made without the extended-field-of-view images, it was considered diagnostic. The radiologist decided if the extended-field-of-view ultrasonography helped spatial orientation, communicate findings, or compare the contralateral side in a single image, or if it was useful for follow-up evaluation. Results By using extended-field-of-view imaging including the surrounding anatomy, 22 musculoskeletal, 8 scrotal, 8 thyroid, 2 breast, and 4 abdominal wall lesions were documented successfully as a single image. Nevertheless, no new cases were diagnosed solely based on the extended-field-of-view images. Extended-field-of-view ultrasonography was considered helpful for spatial orientation in 25 cases (56.8%), for comparing the contralateral side in 16 cases (36.3%), and for communicating findings in 20 cases (45.4%). It was useful for follow-up evaluation in 13 cases (29.5%). Conclusions None of the extended-field-of-view images was diagnostic. However, they did provide valuable additional information and better documentation of the lesions.

Published: May 2009

Objective To calculate the effective dose from diagnostic computed tomography (CT) scans in Saskatchewan, Canada, and compare with other reported dose levels. Methods Data from CT scans were collected from 12 scanners in 7 cities across Saskatchewan. The patient age, scan type, and selected technique parameters including the dose length product and the volume computed tomography dose index were collected for a 2-week period. This information then was used to calculate effective doses patients are exposed to during CT examinations. Data from 2,061 clinically indicated CT examinations were collected, and of them 1,690 were eligible for analysis. Every examination during a 2-week period was recorded without selection. Results The average provincial estimated patient dose was as follows: head, 2.7 mSv (638 scans; standard deviation [SD], ±1.6); chest, 11.3 mSv (376 scans; SD, ±8.9); abdomen-pelvis, 15.5 mSv (578 scans; SD, ±10.0); abdomen, 11.7 mSv (80 scans; SD, ±11.48), and pelvis, 8.6 mSv (18 scans; SD, ±6.04). Significant variation in dose between the CT scanners was observed ( P = .049 for head, P = .001 for chest, and P = .034 for abdomen-pelvis). Conclusions Overall, the estimated dose from diagnostic CT examinations was similar to other previously published Canadian data from British Columbia. This dose varied slightly from some other published standards, including being higher than those found in a review conducted in the United Kingdom in 2003.
The Politics of Naming: Derozio in Two Formative Moments of Literary and Political Discourse, Calcutta, 1825–31
Authors: CHAUDHURI ROSINKA 
Published: May 2009

AbstractHenry Derozio, India's first modern poet, used the pseudonym ‘An East Indian’ for several poems he published in his lifetime, and he may have used it again in a heated controversy that played itself out in the correspondence columns of the India Gazette, Calcutta's leading newspaper, from May 26 to June 5, 1825. The occasion was an editorial comment upon a community of office-goers in the city—called, at the time, ‘sircars’—who had set up a literary association. This editorial was widely perceived to be reactionary, and civil society responded vigorously in protest at the injustice. The sequence of editorials and letters published on this issue, which seem to have been written by Englishmen, East Indians and Indians alike, demonstrate a remarkable liberalism of spirit and a free-thinking attitude to ethnicity that was soon to disappear in the stiffening boundaries of a racially divided society. 1825 was also the year that Derozio began to publish prolifically in the poetry columns of newspapers and periodicals in the city; by the time he died, in 1831, he had published two books of poems in 1827 and 1828 and had created a revolution of sorts among the radicalised youth of the Hindu College, from which he had been dismissed for his role in their alienation from tradition. In 1831, a few months before his death, Derozio addressed a mammoth meeting called to commemorate the return of John Ricketts, the East Indian representative, from his mission to the English houses of Parliament for a redressal of the community's grievances. Using these two lost occasions—the public correspondence and the meeting—both concerned with the politics of naming, this paper will attempt to present the early radical interventions of the mixed-race community in initiating a discourse of civic rights and human dignity which led, ultimately, to organised attempts at constitutional change and political reform in India, whose estimation is underrated in present-day contexts.
Bullion for Trade, War, and Debt-Relief: British Movements of Silver to, around, and from Asia, 1760–1833
Authors: BOWEN H. V. 
Published: May 2009

AbstractThis paper provides the first detailed assessment of British exports of silver to Asia during the initial phase of imperial expansion in India. It demonstrates that, contrary to the views of some historians, exports of silver were at times very considerable, notably after 1785, when they were used to fund war and debt-relief in India, as well as for trade. Focus is on the East India Company, but attention is paid to private exports, to British transfers of silver around Asia, and the paper ends with an analysis of ‘reverse’ flows to Britain established after 1810.
An acoustic analysis of prosody in high-functioning autism

Published: May 2009

ABSTRACTThis paper examined the fundamental frequency variation in the narratives of individuals with high-functioning autism (HFA) and typical controls matched on age, IQ, and verbal abilities. Study 1 found increased fundamental frequency variation in the speech of 21 children and adolescents with HFA when compared to 21 typical controls. Study 2 replicated the findings from Study 1 with a younger sample of 17 children with HFA and 17 typical controls. In addition, Study 1 found evidence that acoustic measurements of prosody were related to clinical judgments of autism-specific communication impairments, although this was not replicated in Study 2. Taken together, these studies provide evidence for differences in expressive prosody in individuals with HFA that can be measured objectively.
Talking about writing: What we can learn from conversations between parents and their young children
Authors: ROBINS SARAH , TREIMAN REBECCA 
Published: May 2009

ABSTRACTIn six analyses using the Child Language Data Exchange System known as CHILDES, we explored whether and how parents and their 1.5- to 5-year-old children talk about writing. Parent speech might include information about the similarity between print and speech and about the difference between writing and drawing. Parents could convey similarity between print and speech by using the wordssay,name, andwordto refer to both spoken and written language. Parents could differentiate writing and drawing by making syntactic and semantic distinctions in their discussion of the two symbol systems. Our results indicate that parent speech includes these types of information. However, young children themselves sometimes confuse writing and drawing in their speech.
Bilingualism and aging: Reversal of the cognate advantage in older bilingual adults
Authors: SIYAMBALAPITIYA SAMANTHA , CHENERY HELEN J. , COPLAND DAVID A. 
Published: May 2009

ABSTRACTThis study aimed to investigate cognate/noncognate processing distinctions in young adult bilinguals and examined whether the previously reported cognate facilitation effect would also be demonstrated in older adult bilinguals. Two groups of Italian–English bilingual participants performed lexical decisions in repetition priming experiments. Results for the younger bilinguals corresponded to previous findings, and indicated the expected reaction time advantage for cognates over noncognates. The older bilinguals, however, only demonstrated a cognate advantage in the within-language condition, and in fact, showed faster reaction times for noncognates when repetition was across languages. These findings are interpreted in the context of the revised hierarchical model and the bilingual interactive activation model and in light of findings regarding the effect of aging on language processing.

AbstractWe provide effective versions of theorems of Furstenberg and Rudolph–Johnson regarding closed subsets and probability measures of ℝ/ℤ invariant under the action of a non-lacunary multiplicative semigroup of integers. In particular, we give an explicit rate at which the sequence {anbkx}n,k becomes dense for a,b fixed multiplicatively independent integers and x∈ℝ/ℤ Diophantine generic.
Maximal entropy measures for piecewise affine surface homeomorphisms
Authors: BUZZI JÉRÔME 
Published: May 2009

AbstractWe study the dynamics of piecewise affine surface homeomorphisms from the point of view of their entropy. Under the assumption of positive topological entropy, we establish the existence of finitely many ergodic and invariant probability measures maximizing entropy and prove a multiplicative lower bound for the number of periodic points. This is intended as a step towards the understanding of surface diffeomorphisms. We proceed by building a jump transformation, using not first returns but carefully selected ‘good’ returns to dispense with Markov partitions. We control these good returns through some entropy and ergodic arguments.
Evaluation framework for the design of an engineering model
Authors: Ben Ahmed Walid , Mekhilef Mounib , Yannou Bernard , Bigand Michel 
Published: May 2009

AbstractAccording to both cybernetics and general system theory, a subject develops and uses an adequate model of a system to widen his/her knowledge about the system. Models are then the interface between a subject and a real-world system to solve a problem and to construct knowledge. Hence, evaluating these models is crucial to ensure the quality of the constructed knowledge. We propose here an evaluation framework to assess complex models based on the intrinsic properties of these models as well as the properties of the derived knowledge. A series of 40 evaluation criteria are proposed under the four systemic axes: ontology, functioning, evolution, and teleology. Through a case study, we show how our evaluation model allows both presenting a given model and assessing it.
Control and benefits of CP4-57 prophage excision in Escherichia coli biofilms
Authors: Wang Xiaoxue , Kim Younghoon , Wood Thomas K 
Published: May 2009

Abstract
Earlier, we discovered that the global regulator, Hha, is related to cell death in biofilms and regulates cryptic prophage genes. Here, we show that Hha induces excision of prophages, CP4-57 and DLP12, by inducing excision genes and by reducing SsrA synthesis. SsrA is a tmRNA that is important for rescuing stalled ribosomes, contains an attachment site for CP4-57 and is shown here to be required for CP4-57 excision. These prophages impact biofilm development, as the deletion of 35 genes individually of prophages, CP4-57 and DLP12, increase biofilm formation up to 17-fold, and five genes decrease biofilm formation up to sixfold. In addition, CP4-57 excises during early biofilm development but not in planktonic cells, whereas DLP12 excision was detected at all the developmental stages for both biofilm and planktonic cells. CP4-57 excision leads to a chromosome region devoid of prophage and to the formation of a phage circle (which is lost). These results were corroborated by a whole-transcriptome analysis that showed that complete loss of CP4-57 activated the expression of the flg, flh and fli motility operons and repressed expression of key enzymes in the tricarboxylic acid cycle and of enzymes for lactate utilization. Prophage excision also results in the expression of cell lysis genes that reduce cell viability (for example, alpA, intA and intD). Hence, defective prophages are involved in host physiology through Hha and in biofilm formation by generating a diversified population with specialized functions in terms of motility and nutrient metabolism.
Postoperative Neurocognitive Dysfunction in Elderly Patients after Xenon versus Propofol Anesthesia for Major Noncardiac Surgery

Published: May 2009

Background
Postoperative cognitive dysfunction (POCD) in elderly patients after noncardiac surgery is a common problem. The noble gas xenon has been demonstrated to exert substantial neuroprotective properties in animal studies. Therefore, this study was designed to assess POCD after xenon anesthesia in comparison to propofol in elderly patients undergoing major noncardiac surgery.

Methods
After approval of the local ethical committee was obtained, 101 patients (American Society of Anesthesiologists physical status I-III; age, 65-83 yr) undergoing elective abdominal or urologic surgery (duration, > 2 h) were enrolled into this randomized, double-blinded controlled pilot study. Patients received anesthesia with sufentanil and either propofol or xenon and were assessed before treatment and 1, 6, and 30 days after treatment using a neuropsychological test battery based on previous studies investigating POCD.

Results
There were no significant differences in terms of age, American Society of Anesthesiologists status, education, duration of surgery, administered analgetics, and preoperative neurocognitive status between study groups. POCD as classified was present in 22 patients (44%) of the xenon group versus 25 patients (50%) of the propofol group 1 day after treatment, in 6 xenon patients (12%) versus 9 propofol patients (18%) 6 days after treatment, and in 3 xenon patients (6%) versus 6 propofol patients (12%) 30 days after treatment. These differences were not statistically significant.

Conclusion
Postoperative impairment of neurocognitive function was observed in a substantial proportion of elderly patients even 30 days after treatment. Xenon-based anesthesia was not associated with decreased incidence of POCD in comparison to propofol.
Opioid Tolerance Blunts the Reduction in the Sevoflurane Minimum Alveolar Concentration Produced by Remifentanil in the Rat
Authors: Gómez de Segura Ignacio A. , de la Vibora Javier Benito , Aguado Delia 
Published: May 2009

Background
Acute opioid tolerance is a known entity leading to reduced analgesic efficacy of these drugs in the postoperative period. However, the development of acute opioid tolerance in the very short term, i.e., during the intraoperative period when opioids are being administered, has not been reported. Therefore, the aim of this study was to determine if acute opioid tolerance could develop and limit the opioid-induced reduction in the minimum alveolar concentration (MAC) for inhalant anesthetics.

Methods
Male Wistar rats were randomly allocated to receive two doses of remifentanil (120 and 240 microg . kg(-1) . h(-1)) under sevoflurane anesthesia, and the sevoflurane MAC was determined before and at two time intervals afterwards. In a second experiment, the low dose of remifentanil was increased once an acute opioid tolerance effect was observed. The sevoflurane MAC was determined from alveolar gas samples at the time of tail clamp.

Results
A remifentanil constant rate of infusion dose-dependently reduced the sevoflurane MAC from 2.4 to 1.8 +/- 0.2 vol% and from 2.3 +/- 0.3 vol% to 1.5 +/- 0.3 vol%, at the low and high doses, respectively. However, 90 min later, when the sevoflurane MAC was redetermined, the observed reduction was blunted to nearly 50% of the previous sevoflurane MAC values. When this acute opioid tolerance effect was observed with the low dose, the sevoflurane MAC reduction originally achieved could be reattained by doubling the dose; i.e., giving the high dose.

Conclusions
Remifentanil efficacy in reducing the sevoflurane MAC diminishes within a short term, suggesting that increased opioid doses may be required to maintain intraoperative analgesia during sevoflurane anesthesia.
