Daily Physical Activities and Sports in Adult Survivors of Childhood Cancer and Healthy Controls: A Population-Based Questionnaire Survey

Background Healthy lifestyle including sufficient physical activity may mitigate or prevent adverse long-term effects of childhood cancer. We described daily physical activities and sports in childhood cancer survivors and controls, and assessed determinants of both activity patterns. Methodology/Principal Findings The Swiss Childhood Cancer Survivor Study is a questionnaire survey including all children diagnosed with cancer 1976–2003 at age 0–15 years, registered in the Swiss Childhood Cancer Registry, who survived ≥5years and reached adulthood (≥20years). Controls came from the population-based Swiss Health Survey. We compared the two populations and determined risk factors for both outcomes in separate multivariable logistic regression models. The sample included 1058 survivors and 5593 controls (response rates 78% and 66%). Sufficient daily physical activities were reported by 52% (n = 521) of survivors and 37% (n = 2069) of controls (p<0.001). In contrast, 62% (n = 640) of survivors and 65% (n = 3635) of controls reported engaging in sports (p = 0.067). Risk factors for insufficient daily activities in both populations were: older age (OR for ≥35years: 1.5, 95CI 1.2–2.0), female gender (OR 1.6, 95CI 1.3–1.9), French/Italian Speaking (OR 1.4, 95CI 1.1–1.7), and higher education (OR for university education: 2.0, 95CI 1.5–2.6). Risk factors for no sports were: being a survivor (OR 1.3, 95CI 1.1–1.6), older age (OR for ≥35years: 1.4, 95CI 1.1–1.8), migration background (OR 1.5, 95CI 1.3–1.8), French/Italian speaking (OR 1.4, 95CI 1.2–1.7), lower education (OR for compulsory schooling only: 1.6, 95CI 1.2–2.2), being married (OR 1.7, 95CI 1.5–2.0), having children (OR 1.3, 95CI 1.4–1.9), obesity (OR 2.4, 95CI 1.7–3.3), and smoking (OR 1.7, 95CI 1.5–2.1). Type of diagnosis was only associated with sports. Conclusions/Significance Physical activity levels in survivors were lower than recommended, but comparable to controls and mainly determined by socio-demographic and cultural factors. Strategies to improve physical activity levels could be similar as for the general population.
Accurate Calculation of Magnetic-Field Intensity Due to Overhead Power Lines With or Without Mitigation Loops With or Without Capacitor Compensation

An accurate method for the evaluation of 50-Hz magnetic fields produced by overhead power lines is presented. The method, which is based on the matrix formalism of multiconductor transmission lines (MTL), allows for a correct evaluation of all the currents flowing in the MTL structure, including the currents in the subconductors of each phase bundle, the currents in the ground wires, the currents in the mitigation loop (if present), and also the earth return currents. Furthermore, the analysis also incorporates the nonuniform character of the structure arising from conductor sagging between towers. Frequency domain magnetic field calculations are performed by vectorial sum of the magnetic effects originated by all the existing currents. For exemplification purposes the case of an actual 400-kV-1.4-GVA single-circuit three-phase line is examined. Results presented include a discussion on the effects of mitigation loops with or without capacitor compensation
Estimating Latent Variable Interactions With Nonnormal Observed Data: A Comparison of Four Approaches

A Monte Carlo simulation was conducted to investigate the robustness of 4 latent variable interaction modeling approaches (Constrained Product Indicator [CPI], Generalized Appended Product Indicator [GAPI], Unconstrained Product Indicator [UPI], and Latent Moderated Structural Equations [LMS]) under high degrees of nonnormality of the observed exogenous variables. Results showed that the CPI and LMS approaches yielded biased estimates of the interaction effect when the exogenous variables were highly nonnormal. When the violation of nonnormality was not severe (normal; symmetric with excess kurtosis < 1), the LMS approach yielded the most efficient estimates of the latent interaction effect with the highest statistical power. In highly nonnormal conditions, the GAPI and UPI approaches with maximum likelihood (ML) estimation yielded unbiased latent interaction effect estimates, with acceptable actual Type I error rates for both the Wald and likelihood ratio tests of interaction effect at N ≥ 500. An empirical example illustrated the use of the 4 approaches in testing a latent variable interaction between academic self-efficacy and positive family role models in the prediction of academic performance.
Detecting Aerobic Bacterial Diversity in Patients With Diabetic Foot Wounds Using ERIC-PCR: A Preliminary Communication

The polymicrobial nature of diabetic foot infection is a reflection of the immune compromised state of the host.The methods of microbial identification based on colony morphology and biochemical characteristics have limitations as they may not differentiate the diverse microorganisms that infect foot wounds. The aim of the present study was to find out the bacterial diversity in diabetic foot infections at genetic level by finger printing, that is, ERIC-PCR (enterobacterial repetitive intergenic consensus -polymerase chain reaction). Nine patients with infected diabetic foot ulcers were recruited to the study. Pus and tissue samples were collected from the wound site. Aerobic bacteria were isolated employing standard microbiological culture methods and their genetic variability was analyzed using the ERIC-PCR. Sensitivity test for these isolates against commonly used antibiotics were performed using disc diffusion method. The standard microbiological culture technique yielded 38 morphotypes of bacteria and their genetic diversity was confirmed by ERIC-PCR assay. Analysis of the similarity index using NTSYSpc 2.1 software revealed 34 types of banding pattern among these isolates. Based on the similarity index these isolates were divided into 7 groups. As many as 8 types of aerobic bacterial isolates were detected from a single patient using the above technique compared with 2 on routine culture analysis. Genetically diverse isolates showed differential sensitivity pattern against commonly used antibiotics in the assay. The observed diversity at genetic level is attributed to variable sensitivity pattern of these isolates against the class of antibiotics. A molecular technique such as ERIC-PCR is a more sensitive detection method than conventional techniques, the potential of which needs to be fully understood.
Extended parenting education in an early parenting centre

This article reports findings from a process and impact study of a residential early parenting centre programme in Australia. The programme supports parents with young children under the age of three, referred from health and child protection services. Multiple sources of data were used from interviews, focus groups, direct observations, observer notes and a parenting sense of competence questionnaire. Qualitative data were analysed using thematic analyses, and paired t-tests were used to test data from the questionnaire. Three themes emerged from thematic analysis of the qualitative data: engaging families, building parenting capacity and transitioning back to the community. Parents’ perceptions of parent competence improved significantly between admission and discharge for participating families. Detailed accounts of the way in which nurses work to achieve positive outcomes in relation to parenting confidence and satisfaction in the short term have provided useful insights into often taken-for-granted support processes in working with referred parents. The complexity of the nurses’ role and implications for nursing practice in residential parenting centres are discussed. Future research is warranted to determine longer-term benefits of this programme being delivered in a residential early parenting centre.
The Impact of Media Exposure on Intention to Purchase Green Electronic Products amongst Lecturers

The purpose of this study is to contribute to the body of knowledge in the area of green product purchase intention within the domain of green marketing, where all activities are designed to generate and to facilitate any exchanges intended to satisfy human needs or wants, such that the satisfaction of these needs or wants occurs, with minimal detrimental impact on the natural environment. Therefore, this study intends to identify the influence of media exposure, on purchase intention of lead-free electronic products (green electronics) amongst lecturers. Through a self-administered questionnaire among 170 lecturers, from USM main campus and USM engineering campus the study found some revealing insights. Through the results of this study, media exposure had a significant positive influence on lecturers’ purchase intention. The theory of planned behavior Azjen (1985) supported the findings of this study for media exposure and purchase intention, which is related to the motivation part of the theory which includes information about a behavior, resulting in motivation to perform a certain behavior.
Correction of myopia and astigmatism using an ablatable mask.

BACKGROUND Most excimer laser refractive procedures use a computer driven mechanical diaphragm to shape the laser beam. Studies are currently underway using an ablatable polymethylmethacrylate (PMMA) mask to transfer a new spherical or toric curve to the cornea for the correction of myopia and astigmatism; it may leave a smoother corneal surface than diaphragm procedures. METHODS As part of a Phase IIb FDA clinical study, 25 eyes of 25 patients underwent excimer laser photorefractive keratectomy using a hand held ablatable mask. Fifteen eyes had attempted spherical corrections of up to 6.00 diopters (D) and 10 had toric corrections of up to 6.00 D of sphere and 2.75 D of astigmatism. RESULTS Seventy-four percent of all eyes achieved uncorrected visual acuity of 20/40 or better--86% in the spherical group and 63% in the astigmatism group. Sixty-nine percent of eyes were within +/- 1 D of the attempted correction. In eyes treated for astigmatism, mean astigmatism decreased from 1.48 D preoperatively to 0.86 D postoperatively. Approximately one half of the eyes treated for astigmatism had a decrease in cylinder of more than 0.5 D. One eye lost 2 Snellen lines of best spherical corrected visual acuity. Video keratography showed toric ablations to result in an elliptical optical zone. Analysis of centration of the procedure showed 66% of ablations centered within 1.0 mm of the center of the pupil aperture. CONCLUSIONS The ablatable mask represents a promising modality for the treatment of eyes with both myopia and myopic astigmatism.
The genes for leukemia inhibitory factor and interleukin-6 are expressed in mouse blastocysts prior to the onset of hemopoiesis

We have investigated the role that hemopoietic regulatory molecules may play in mouse embryogenesis prior to the appearance of hemopoietic stem cells or their microenvironments. Using polymerase chain reaction analysis, we detected mRNA transcripts for interleukin-6 (IL-6) and leukemia inhibitory factor (LIF) but not for granulocyte-macrophage colony-stimulating factor (GM-CSF) or IL-3 in mouse blastocysts at 3.5 days of gestation. Functional IL-6 protein was also detected in cultured blastocysts as a secreted product, as was an activity consistent with the presence of LIF protein. The expression of IL-6 and LIF in blastocysts prior to hemopoiesis suggests that these proteins may regulate the growth and development of trophoblasts or embryonic stem cells.
Affect and managerial performance: A test of the sadder-but-wiser vs. happier-and-smarter hypotheses.

We thank Jennifer Halpern for her role in the original planning of this study and for her contributions to the development of the coding scheme used in this project. This study was made possible by a faculty research grant to the first author from the Institute of Industrial Relations at the University of California at Berkeley. This study provides a comparative test of two psychological theories concerning the relationship between affect and performance. Managerial simulations are used to test whether people who are positive in disposition perform better or worse on both decisional and interpersonal tasks. Results are consistent in supporting the happier-and-smarter as opposed to the sadder-but-wiser hypothesis, since they show positive relationships between dispositional affect and performance. The results are discussed in terms of their relevance to both the older literature on links between satisfaction and performance and the more recent controversy over the dispositional approach to job attitudes.

A Contingency Perspective on External Component Reuse and Software Project Success

Software reuse can lower costs and increase the flexibility of the software development process. Despite a large body of research focused on technical factors, there is still limited research on how companies reuse exiting components. In this study, we analyzed the reuse of external software components by taking a contingency approach. Using a survey of IT managers in the software industry, we empirically found that the use of external software components in an organization leads to better outcomes of the software development process. Among large companies, organic organizations adopt external reuse strategies more aggressively than mechanistic organizations. Architecture modularity is a significant driver of software reuse strategies. Finally, our findings suggest that some organizations may view external reuse as a long-term strategy that allows them to organize and deploy resources to achieve efficiency. External software reuse can thus be seen as an effective organization strategy to improve software project success.
Delaware Longitudinal Study of Fraction Learning: Implications for Helping Children With Mathematics Difficulties

The goal of the present article is to synthesize findings to date from the Delaware Longitudinal Study of Fraction Learning. The study followed a large cohort of children (N = 536) between Grades 3 and 6. The findings showed that many students, especially those with diagnosed learning disabilities, made minimal growth in fraction knowledge and that some showed only a basic grasp of the meaning of a fraction even after several years of instruction. Children with low growth in fraction knowledge during the intermediate grades were much more likely to fail to meet state standards on a broad mathematics measure at the end of Grade 6. Although a range of general and mathematics-specific competencies predicted fraction outcomes, the ability to estimate numerical magnitudes on a number line was a uniquely important marker of fraction success. Many children with mathematics difficulties have deep-seated problems related to whole number magnitude representations that are complicated by the introduction of fractions into the curriculum. Implications for helping students with mathematics difficulties are discussed.
Attractiveness of Insecticide Baits for Cockroach Control (Dictyoptera: Blattellidae)Laboratory and Field Studies

Abstract Several insecticide bait formulations were evaluated for their attractiveness to cockroaches in olfactometer assays in the laboratory and in trapping experiments in the field. Included in the assays were bait stations, gels, pastes, and a powder that contained one of the following active ingredients: abamectin, boric acid, chlorpyrifos, or hydramethylnon. There were significant differences among the baits in their attractiveness to the German cockroach, Blattella germanica (L.). In trapping experiments, Avert powder (abamectin), Maxforce station and gel, and Siege gel (all hydramethylnon) were consistently attractive to B. germanica adults and nymphs. Laboratory olfactometer assays with adult males confirmed these results and showed that nymphs were as responsive as males whereas females were less responsive. Our bioassays also demonstrate that attractiveness of bait can be dramatically affected by the age of the bait. One week of aging significantly reduced the attractiveness of Avert powder in both laboratory and field assays. Aging, however did not diminish the attractiveness of Maxforce gel, indicating that the formulation may be critical for retention of attractiveness of baits. Baits that were most attractive to the German cockroach were also the most attractive to nymphs and adults of the brownbanded cockroach, Supella longipalpa (F.).
Motoric Dominance and Sporting Excellence: Training versus Heredity

In the past two decades, laterality in sports has become clearly established. In particular, the concept of motoric dominance in sports has been a fertile area for laterality research. The literature is consistent with the view that in certain sporting skills, sporting competitors with specific motoric-dominance patterns enjoy an advantage over other competitors and are overrepresented in some sports. Two theoretical interpretations have been offered to explain this imbalance of motoric-dominance distribution among sporting individuals: hypotheses of “innate superiority” and “strategic advantage. ” This paper presents an overview the two hypotheses, along with relevant work so far reported and identifies directions for further empirical research. The theoretical and practical implications of research on laterality in human motor performance are discussed.
Perceived Health Benefits and Soy Consumption Behavior: Two-Stage Decision Model Approach

A two-stage decision model is developed to assess the effect of perceived soy health benefits on consumers' decisions with respect to soy food. The first stage captures whether or not to consume soy food, while the second stage reflects how often to consume. A conceptual/analytical framework is also employed, combining Lancaster's characteristics model and Fishbein's multi-attribute model. Results show that perceived soy health benefits significantly influence both decision stages. Further, consumers' negative perceptions regarding soy (unappetizing taste and inconvenience) have a substantially greater impact on soy consumption behavior than their perceptions about soy health benefits. This finding carries significant implications for the soy industry. Additionally, this health benefit perception mediates the effect of general health-related factors such as knowledge, motivation, and awareness on soy consumption behavior. Our results also underscore the importance of current FDA-regulated health claims in stimulating consumer demand for soy foods.
Andrology: Analysis of sperm movement in relation to the oxidative stress created by leukocytes in washed sperm preparations and seminal plasma

The addition of luminol to unprocessed semen samples resulted in the generation of chemiluminescent signals, the intensity of which was highly correlated with the level of leukocyte contamination. Despite the spontaneous oxidant-generating capacity of seminal leukocytes, no correlations were observed between leukocyte contamination and the fertility status of the subjects or any aspect of the semen profile, including the motility of the spermatozoa or their performance in a hyaluronate penetration assay. Luminol-dependent chemiluminescence and leukocyte contamination were also correlated in washed sperm suspensions prepared either by repeated centrifugation or on discontinuous Percoll gradients. However, in such sperm suspensions, the spontaneous generation of oxidants by contaminating leukocytes (> 2 x 10(4) leukocytes/ml) was invariably associated with a decreased capacity for movement. Moreover, causative associations between leukocyte contamination, reactive oxygen species generation, lipid peroxidation and impaired sperm motility were revealed by experiments involving the selective addition or removal of activated leukocytes. From these observations we can conclude that low concentrations of leukocytes are a common feature of the human ejaculate and can impair sperm function, particularly in the absence of seminal plasma. These findings have implications for our understanding of the importance of leukocytospermia in defining the fertility of human spermatozoa in vivo and in vitro.
Thymoquinone Ameliorates Acute Renal Failure in Gentamicin-Treated Adult Male Rats

Background: Gentamicin (GEN) is considered as a main aminoglycoside antibiotic medicine. The top therapeutic side effect of GEN is nephrotoxicity. The current research was proposed to determine the protective effect of thymoquinone (TQ) on GEN-induced acute renal failure (ARF). Methods: The rats were divided into 6 groups: sham group, control group, GEN-treated group and the TQ-treated groups. At the end of the research period, the serum blood urea nitrogen (BUN) and creatinine (Cr) were measured. The kidneys were then removed for evaluating malondialdehyde (MDA), reduced glutathione (GSH), interleukins IL-6, IL-10, IL-18 and IL-1β, tumor necrosis factor α (TNF-α), superoxide dismutase (SOD) and glutathione peroxidase (GPx) levels. Results: GEN induced a raise in the levels of serum Cr, BUN and also the levels of MDA, IL-6, IL-18, IL-1β and TNF-α with decease in GSH, SOD, GPx and IL-10 in the kidney (p < 0.05). The data illustrated that the significant elevation in the levels of serum Cr, BUN, MDA, IL-6, IL-18, IL-1β, TNF-α and also the reduction of GSH, SOD, SOD, GPx, IL-10 in the kidney were ameliorated in the TQ-treated groups versus the untreated group, in a dose-dependent manner (p < 0.05). Conclusion: The present investigation proposes that TQ may be ameliorated ARF through modulation of the oxidative stress and inflammatory responses.
The natural behavior of mononuclear phagocytes in HTS formation

Hypertrophic scars (HTS) are caused by trauma or burn injuries to the deep dermis and are considered fibrosis in the skin. Monocytes, M1 and M2 macrophages are mononuclear phagocytes. Studies suggest that M2 macrophages are profibrotic and might contribute to HTS formation. Our lab has established a human HTS‐like nude mouse model, in which the grafted human skin develops red, raised, and firm scarring, resembling HTS seen in humans. In this study, we observed the natural behavior of mononuclear phagocyte system in this nude mouse model of dermal fibrosis at multiple time points. Thirty athymic nude mice received human skin grafts and an equal number of mice received mouse skin grafts as controls. The grafted skin and blood were harvested at 1, 2, 3, 4, and 8 weeks. Wound area, thickness, collagen morphology and level, the cell number of myofibroblasts, M1‐ and M2‐like macrophages in the grafted skin, as well as monocyte fraction in the blood were investigated at each time points. Xenografted mice developed contracted and thickened scars grossly. The xenografted skin resembled human HTS tissue based on enhanced thickness, fibrotic orientation of collagen bundles, increased collagen level, and infiltration of myofibroblasts. In the blood, monocytes dramatically decreased at 1 week postgrafting and gradually returned to normal in the following 8 weeks. In the xenografted skin, M1‐like macrophages were found predominantly at 1–2 weeks postgrafting; whereas, M2‐like macrophages were abundant at later time points, 3–4 weeks postgrafting coincident with the development of fibrosis in the human skin tissues. This understanding of the natural behavior of mononuclear phagocytes in vivo in our mouse model provides evidence for the role of M2‐like macrophages in fibrosis of human skin and suggests that macrophage depletion in the subacute phases of wound healing might reduce or prevent HTS formation.
