The physiological relevance of wet versus dry differential scanning calorimetry for biomaterial evaluation: a technical note
Authors: Zeugolis Dimitrios I , Raghunath Michael 
Published: July 2010

AbstractCollagen and its denatured form, gelatin, have been extensively used as scaffolds for tissue engineering and tissue repair applications. Denaturation temperature, commonly measured using differential scanning calorimetry (DSC), for biomaterial applications is a significant physical property that will determine the stability of a potential implant at body temperature. In order to imitate a clinical setting, DSC should be run under fully hydrated conditions. We show here that for hydrophobic polymers such as poly(ε‐caprolactone) and chitosan there is no significant difference between dry and wet DSC operation (p > 0.05). In contrast, for hydrophilic polymers such as collagen, gelatin, poly(ethylene glycol) (40 kDa) and poly(ethylene oxide) (900 kDa) significant differences occur between measurements in the dry and the wet state (p < 0.0011). Moreover, we demonstrate that only when wet DSC is carried out are we able to separate the unique crystalline structure of collagen from its randomly coiled heat‐denatured by‐product gelatin (p < 0.0005). We therefore recommend running DSC under fully hydrated conditions when the function and properties of a biomaterial are under investigation. Copyright © 2010 Society of Chemical Industry
Empowering Latino families: Effects of a culturally responsive intervention for low‐income immigrant Latino parents on children's behaviors and parental stress
Authors: Ceballos Peggy L. , Bratton Sue C. 
Published: July 2010

AbstractThis randomized, controlled study examined the effectiveness of Child Parent Relationship Therapy (CPRT) in school settings with 48 low‐income Latino immigrant parents whose children were identified with behavioral concerns. Results from a 2 (group) × 2 (measures) split plot analysis of variance indicated that parents who participated in 11 weeks of CPRT reported statistically significant decreases (p < .001) in child behavior problems and parent–child relationship stress. Large treatment effects were demonstrated for all dependent variables. Clinical significance of findings and cultural considerations are discussed. © 2010 Wiley Periodicals, Inc.
Children's self‐regulated learning profile in language and mathematics: The role of task value beliefs
Authors: Metallidou Panayiota , Vlachou Anastasia 
Published: July 2010

AbstractThis study explored the self‐regulated learning (SRL) profile of upper elementary (fifth and sixth grade) school children who were differentiated in their task value beliefs (low and high) in language and mathematics. Students' SRL profile involved their teachers' ratings of achievement outcomes and SRL behaviors. The subscale of task value beliefs from the Motivational Self‐Regulated Learning Questionnaire (MSLQ) was administered to the children, and their teachers completed a battery of scales and measurements concerning students' achievement and SRL behaviors. The results confirm previous evidence indicating that SRL involves high levels of motivation, metacognition, and strategic action. Furthermore, the results support the domain‐specific character of task value beliefs. Differences in teachers' evaluations about the achievement outcomes and SRL behaviors regarding the two groups of students (low and high in task value beliefs) were found significant mostly in the domain of mathematics. Students with high value beliefs in mathematics were described as more cognitively, metacognitively, and motivationally competent learners as compared to students with lower value beliefs. The results suggest that future intervention studies should focus on strengthening task value beliefs in “threatening” school subjects, such as mathematics, from the elementary school years. © 2010 Wiley Periodicals, Inc.
Type 1 diabetes mellitus case decisions: Health‐related service considerations for school psychologists
Authors: Schmitt Ara J. , Wodrich David L. , Lazar Susan 
Published: July 2010

AbstractType 1 diabetes mellitus (T1DM) is a chronic illness that can impact learning and often requires medical management in the school setting. School psychologists must therefore be knowledgeable of special service eligibility criteria associated with T1DM, the health‐related services often required of such students, and what health‐related services schools are obliged to provide. Although federal regulations speak to special service eligibility criteria to consider for children with T1DM, such codes do not outline what health services schools are expected to provide. One way to glean this information is by examining published case decisions involving diabetes health‐related services in the schools. Themes and examples in five decision categories provide vital information for school psychologists regarding school service planning for T1DM. © 2010 Wiley Periodicals, Inc.
Identifying predictors of emotional exhaustion among special education paraeducators: A preliminary investigation
Authors: Shyman Eric 
Published: July 2010

AbstractThe purpose of this preliminary study was to identify predictors of emotional exhaustion among special education paraeducators. A sample of 100 paraeducators in public and specialized alternative setting schools was used to determine whether self‐reported levels of emotional exhaustion and other job‐related factors were reported. Using hierarchical regression analysis, the researcher investigated whether predictors of emotional exhaustion could be determined. Results indicated that a notable level of emotional exhaustion was reported among the sample and that role conflict, emotional demand, sense of efficacy, and supervisor support were significant predictors of emotional exhaustion. The results of this study are intended to be used to guide future studies to further investigate this topic. © 2010 Wiley Periodicals, Inc.
Reciprocal peer tutoring and repeated reading: Increasing practicality using student groups
Authors: Oddo Maria , Barnett David W. , Hawkins Renee O. , Musti‐Rao Shobana 
Published: July 2010

AbstractPrevious research has investigated the efficacy of peer‐mediated repeated reading (RR) interventions carried out by student dyads. This research extends the existing research by investigating the impact of RR on oral reading fluency and comprehension when carried out by a teacher in small groups of fourth‐grade students. Outcomes were analyzed using a multiple baseline single case design across groups in addition to supplementary analyses (dual level and trend criteria, percentage of non‐overlapping data, class box plots). Visual analysis of results indicated that RR was effective in improving levels of reading fluency and reading comprehension skills of four targeted students as well as classwide performance in fluency and comprehension. Acceptability ratings showed that the small group format was easy to implement and acceptable to the teacher and students. Despite positive findings, RR may need to be supplemented by other instructional and practice strategies to promote consistent and comprehensive changes beyond fluency. © 2010 Wiley Periodicals, Inc.
Proteomic analysis identifies highly antigenic proteins in exosomes from M. tuberculosis‐infected and culture filtrate protein‐treated macrophages
Authors: Giri Pramod K. , Kruh Nicole A. , Dobos Karen M. , Schorey Jeff S. 
Published: July 2010

AbstractExosomes are small 30–100 nm membrane vesicles released from hematopoietic and nonhematopoietic cells and function to promote intercellular communication. They are generated through fusion of multivesicular bodies with the plasma membrane and release of interluminal vesicles. Previous studies from our laboratory demonstrated that macrophages infected with Mycobacterium release exosomes that promote activation of both innate and acquired immune responses; however, the components present in exosomes inducing these host responses were not defined. This study used LC‐MS/MS to identify 41 mycobacterial proteins present in exosomes released from M. tuberculosis‐infected J774 cells. Many of these proteins have been characterized as highly immunogenic. Further, since most of the mycobacterial proteins identified are actively secreted, we hypothesized that macrophages treated with M. tuberculosis culture filtrate proteins (CFPs) would release exosomes containing mycobacterial proteins. We found 29 M. tuberculosis proteins in exosomes released from CFP‐treated J774 cells, the majority of which were also present in exosomes isolated from M. tuberculosis‐infected cells. The exosomes from CFP‐treated J774 cells could promote macrophage and dendritic cell activation as well as activation of naïve T cells in vivo. These results suggest that exosomes containing M. tuberculosis antigens may be alternative approach to developing a tuberculosis vaccine.

Published: July 2010

AbstractObjectives: Studies on colorectal cancer screening among specific Asian American groups are limited despite the fact that Asians are comprised of culturally distinct subgroups. The purpose of this study was to investigate the impact of cultural characteristics on colorectal cancer screening adherence among Filipinos in the United States.Methods: One hundred and seventeen Filipino men and women aged 50 years or older participated in the cross‐section research design. Lifetime proportion of immigration, language preference and cultural beliefs of personal control regarding health outcomes measured cultural characteristics. Demographic and healthcare variables were also measured to describe the study sample. Participant recruitment employed culturally responsive sampling methods.Results: There was no significant association between language preference and screening. Likewise, perceived personal internal control of health outcome was not related to screening. However, personal external control revealed a marginally significant association. The percent of lifetime residence in the United States was significantly greater among those who were adherent to screening than those who were not adherent. After adjusting for demographic and healthcare variables, the relationship between length of immigration and screening adherence was no longer significant. Finally, age and doctor's recommendation showed significant impact on colorectal cancer screening adherence.Discussion: This pilot study adds to the knowledge regarding cultural factors associated with colorectal cancer screening behaviors among Filipino Americans. Future research is needed to confirm findings that will be useful in developing culturally appropriate strategies to increase screening adherence. Copyright © 2010 John Wiley & Sons, Ltd.
Pulsed Plasma Enhanced Chemical Vapor Deposition of Poly(allyl alcohol) onto Natural Fibers
Authors: Malkov Galiya S. , Fisher Ellen R. 
Published: July 2010

AbstractPulsed plasma enhanced chemical vapor deposition was used to coat natural fibers of silk, wool, and cotton with poly(allyl alcohol) films. Untreated and coated fibers were characterized using X‐ray photoelectron spectroscopy (XPS), electron paramagnetic resonance (EPR), and scanning electron microscopy. Coated fibers had very similar XPS high resolution C1s spectra, suggesting the coatings are uniformly and conformally coated, regardless of fiber type. EPR data show strong signals from incorporated radicals in all three of the coated fibers, with the strongest signal arising from the coated cotton fibers, indicating more free radicals are formed during plasma treatment of cotton. Tensile strength tests reveal coated wool and silk fibers were significantly stronger than their uncoated counterparts.magnified image
Depressive symptoms in children with cystic fibrosis and parents and its effects on adherence to airway clearance
Authors: Smith Beth A. , Modi Avani C. , Quittner Alexandra L. , Wood Beatrice L. 
Published: July 2010

AbstractBackgroundLittle is currently known about the co‐morbidity of depression and cystic fibrosis (CF) and there is currently no empirical research on the effects of depressive symptoms on adherence in children and adolescents with CF. The primary aim of this study was to evaluate the extent of depressive symptoms in children and adolescents with CF and their parents, and determine whether depressive symptoms in the child and/or parent was associated with adherence to airway clearance. We also evaluated whether children's perceptions of relational security with a parent were associated with adherence to airway clearance.MethodsParticipants included 39 children with CF ages 7–17 years and their primary caregivers. Depressive symptoms were measured with the Children's Depression Inventory (CDI) and the Center for Epidemiological Studies‐Depression Scale (CES‐D). The Relatedness Questionnaire assessed the quality of parent–child relational security. Adherence to airway clearance was measured using the daily phone diary (DPD), an empirically validated adherence measure for youth with CF.ResultsRates of depressive symptoms were elevated in children with CF and their parents (29% for children; 35% for mothers; 23% for fathers). Child depressive symptoms were significantly associated with lower rates of adherence to airway clearance, after controlling for demographic variables (r = −0.34, P = 0.02). Child depressive symptoms were associated with worse perceptions of parental relationships (t(35) = 3.2; P = 0.002) and the quality of this relationship was also related to worse adherence (r = 0.42, P = 0.005).ConclusionsA large percentage of youth with CF and their parents reported elevated symptoms of depression. Children scoring in the depressed range on a standardized screening measure and those with less secure parent–child relationships were at greatest risk for poor adherence. Thus, depressive symptoms and family relationships are appropriate targets for adherence promotion interventions, which may ultimately improve health outcomes. Pediatr.

Novel surgical technique for insertion of pleuroperitoneal shunts for bilateral chylous effusions in Ex preterm infant at term corrected age
Authors: Vasu V. , Ude C. , Shah V. , Lim E. , Bush A. 
Published: July 2010

AbstractNeonatal chylothorax is a relatively uncommon condition. Here we describe the case of an extremely preterm infant with bilateral chylous effusions which were resistant to conventional medical management and were ultimately managed with the insertion of pleuroperitoneal shunts using a novel surgical technique. Subsequently the infant recovered and the shunts could be removed. We report this case to highlight that such shunts can be inserted even in tiny preterm infants with minimally invasive techniques, and be extremely successful in managing chylothorax, pending spontaneous recovery.

Published: July 2010

AbstractA major problem for patients with cystic fibrosis (CF) is the maintenance of adequate nutrition to maintain normal growth. The hypotheses that poor nutrition could be due to smell and/or taste dysfunction has been pursued in several studies with contradictory results. None, however, investigated whether inadequate nutrition is due to CF patients having different liking for foods compared to healthy children and whether liking can be linked to specific changes in smell or taste function. Here, the relationships between food liking, BMI, and smell and taste function in 42 CF and 42 healthy 5‐ to 18‐year olds is pursued. A three‐choice 16‐item odor identification test and a gustatory identification test involving five concentrations of sweet, sour, bitter, and salty tastes, were used to assess chemosensory function. Food liking was assessed using a 94‐item questionnaire. Patients identified significantly fewer odors than controls (89.8% vs. 95.7% correct; P < 0.001). However, only a few patients were affected and their loss of olfactory function was not substantial and unlikely to affect their liking for foods. Taste identification was similar for the two groups (patients 92.6% vs. controls 94.2% correct). There was no correlation between age and odor identification ability, but taste performance improved with age (r = 0.39, P < 0.05), suggesting cognition was the cause. Patients liked several types of foods and high‐fat foods more than the controls. Both groups had a similar liking for low‐fat foods and both liked high‐fat foods more than low‐fat foods. No significant relationships existed between FEV1 and smell or taste function or liking for foods, the BMI of the groups were similar and there was no relationship between BMI and smell or taste function. The results indicate that the abnormal eating behavior reported for many CF patients is not due to changes in chemosensory function which remains normal in most CF patients at least to 18 years of age.

AbstractBackgroundThe EPIC Observational Study is an ongoing prospective cohort study investigating risk factors for and clinical outcomes associated with early Pseudomonas aeruginosa (Pa) acquisition in young children with cystic fibrosis (CF).Objectives and HypothesisTo describe the baseline characteristics of the cohort and evaluate associations between potential risk factors and nutritional and respiratory characteristics at enrollment. We hypothesized that distinct demographic and environmental risk factors could be identified for poorer nutritional status and lung function at enrollment.MethodsDuring 2004–2006, 1,700 children with CF were enrolled at 59 US CF centers. Children ≤12 years were eligible if they had no prior Pa infection (Pa‐Never) or, if prior isolation of Pa from respiratory cultures, at least a 2‐year history of Pa negative cultures (Pa‐Past).ResultsOne thousand one hundred seventeen participants (65.7%) were Pa‐Never and 583 (34.3%) Pa‐Past. Pa‐never patients had a lower proportion of CFTR genotypes with both mutations in functional classes I, II, or III), higher lung function and less respiratory symptoms. Diagnosis after newborn or prenatal screening was associated with significantly higher mean weight, height, and FEV1 at enrollment, while maternal smoking during pregnancy appeared to worsen these parameters.ConclusionsChildren in this cohort with a remote history of Pa infection had a higher proportion of CFTR genotypes associated with severely reduced CFTR function as well as lower lung function and more respiratory symptoms than those without prior Pa infection. These observed differences in respiratory indices may reflect the impact of prior Pa airway infection and/or of CFTR genotype or other genetic factors predisposing both to earlier Pa acquisition and more severe lung disease. Key characteristics associated with nutritional and pulmonary status at enrollment included diagnosis after prenatal or neonatal screening (protective) and in utero cigarette exposure (harmful).

Wrapping effects in supersymmetric gauge theories
Authors: Fiamberti F. 
Published: July 2010

AbstractSeveral perturbative computations of finite‐size effects, performed on the gauge side of the AdS/CFT correspondence by means of superspace techniques, are presented. First, wrapping effects are analyzed in the standard 𝒩 = 4 theory, by means of the calculation of the four‐loop anomalous dimension of the Konishi operator. Then, a similar computation at five loops is described. Afterwards, finite‐size effects are studied in the β‐deformed case, where thanks to the reduced number of supersymmetries the simpler class of single‐impurity operators can be considered, so that the leading corrections to the anomalous dimensions at generic order can be reduced to the computation of a class of integrals. Explicit results are given up to eleven loops. A further chapter is dedicated to the computation of the leading finite‐size effects on operators dual to open strings. In the end, some comments are made and proposals for future developments are discussed.

Published: July 2010

AbstractBACKGROUNDp53 is a transcription factor that regulates the cell cycle, DNA repair, and apoptosis. A variant at codon 72, rs1042522, results in altered activities for p53 and is, notably, differentially distributed among different ethnic populations. However, associations of this variant with cancer in men of African descent have not been explored. Herein, we tested the hypothesis that rs1042522 was associated with prostate cancer (PCa) risk.MATERIALS AND METHODSGenotypes were determined by PCR‐RFLP methods in a study population of African descent consisting of 266 PCa patients and 196 male controls.RESULTSOur results indicate that the p53 polymorphism may be associated with increased risk of PCa. Genotypes were significantly and marginally associated with PCa risk using the dominant and log‐additive genetic models (OR = 1.53, 95% CI: 1.02–2.29, P = 0.04; OR = 1.33, 95% CI: 0.99–1.78, P = 0.06, respectively). After adjusting for age, the associations with PCa remained, but results were not statistically significant (OR = 1.48, 95% CI: 0.95–2.31, P = 0.08; OR = 1.30, 95% CI: 0.95–1.80, P = 0.10, respectively).CONCLUSIONSThe present study demonstrates that population‐dependent differences in allele frequencies associated with health disparities provide a valuable framework for the interrogation of complex diseases in all populations.

The development of integrated pest management for the control of mushroom sciarid flies, Lycoriella ingenua (Dufour) and Bradysia ocellaris (Comstock), in cultivated mushrooms
Authors: Shamshad Afsheen 
Published: July 2010

AbstractMushrooms are susceptible to a range of diseases and pests that can cause serious crop loss. Effective pest and pathogen control is a very important factor for the maintenance of efficient production of cultivated mushrooms. Integrated pest management in mushrooms is reliant upon four main principals/elements: sanitation, exclusion, monitoring and pest control. Bradysia ocellaris (Comstock) and Lycoriella ingenua (Dufour) (Diptera: Sciaridae) are major pests of cultivated mushrooms, Agaricus bisporus (Lange) Imbach. These pests cause losses in yield through larval damage of the compost, mycelium and sporophores, and affect the structural features of the compost itself. Adult flies of these species also act as vectors for the introduction of mites and fungal diseases in cultivated mushrooms. Copyright © 2010 Society of Chemical Industry
