African-American and Hispanic Perceptions of HIV Vaccine Clinical Research: A Qualitative Study
Authors: Toledo Lauren , McLellan-Lemal Eleanor , Arreola Sonya , Campbell Chadwick , Sutton Madeline 
Published: January 2014

Purpose. To examine perceptions of phase-I human immunodeficiency virus (HIV) vaccine trial participation among African-Americans and Hispanics in San Francisco, California. Design. Qualitative, semistructured interviews. Setting. San Francisco Department of Health. Participants. Thirty-six African-American and Hispanic men and women, 18 to 50 years of age, residing in the San Francisco Bay Area. Method. Purposive sampling using advertisements, community-based organization rosters, and snowball referrals. Thematic analysis of transcripts identified salient themes and patterns. Results. Participants viewed participation in HIV research as important; however, they held that HIV was not a health priority given limited awareness about HIV research or beliefs that only infected or high-risk persons were eligible for participation. Altruism and personal gain, trustworthy trial staff, convenient schedules and facilities, and involvement of trusted community groups in recruitment were perceived to motivate participants. Concerns about the social consequences of participating in HIV research and product-related side effects were seen as discouraging participation. Limitations include the possibility that participants in interview research have more favorable views of biomedical research than those who refuse to participate. Conclusion. Historically, African-Americans and Hispanics in the United States have had limited participation in HIV trials. Understanding their perceptions of HIV biomedical research, identifying facilitators and barriers to participation, addressing misinformation about HIV, distorted risk perceptions, HIV stigma, and providing accessible opportunities to participate are imperative to ensure health equity and generalizability of findings.

Published: January 2014

Purpose. To test the effects of a family-centered intervention for enhancing intentions to exercise among African-American boys with nonresident fathers. Design. Quasi-experimental, intervention study. Setting. Two Midwestern cities. Subjects. A total of 287 nonresident African-American fathers and their 8- to 12-year-old sons (n = 158 intervention dyads; n = 129 comparison dyads). Intervention. The Fathers and Sons Program is a 15-session family-based intervention focused on promoting the health of African-American boys by enhancing the parenting attitudes and behaviors of their nonresident fathers and positively influencing parent-child interactions. Measures. Demographic information and intervention outcomes were assessed at baseline and follow-up via self-report. Analysis. Descriptive statistics, logistic regression, and structural equation modeling. Results. The intervention was successful in improving the exercise intentions of boys (B = .246; p = .005; B = .210; p = .012). The effect was not direct; increasing contact between fathers and sons (B = .154; p = .001), enhancing the quality of their relationship (B = .366; p < .001), and improving fathers' own intentions to exercise (B = .265; p = .001) were mediating factors. Conclusion. Interventions aimed at improving exercise intentions among African-American boys with nonresident fathers should focus on relational factors.

ABSTRACT
The purpose of this article was to illustrate the orthodontic treatment in a case of implant removal. When an implant is used as anchorage the treatment alternative does not require patient compliance, but sometimes it becomes a problem in case of removal indication of a good implant made to provide a more functional and attractive alternative than removable prostheses to achieve orthodontic treatment strategy. The results seem to suggest that the extraction of the implant provide a valid treatment procedure for orthodontic purposes in case of osseointegrated implant. Successful treatment results were achieved in the reduction of the bimaxillary protrusion of Angle Class II division 1 subdivision malocclusion with a good gingival and dental result in an adult patient.

Twin City Ethnopolitics
Authors: Rasporich Anthony W. 
Published: January 2014

Urban politics and ethnicity have been intimately linked in the history of the twin cities, Port Arthur and Fort William, later amalgamated into Thunder Bay in 1970. The historic relatinship between political and urban development and ethnicity may be seen in three distinct phases: (1) the era of ethnic exclusion and factionalism in the period 1900-30, when ethnic groups settled into "foreign" enclaves, or "quarters," and largely stood apart from mainstream political parties, particularly those groups like the Ukrainians and Finns who were active on the radical left; (2) the two decades of radical protest and emergent ethnopolitcal activism from 1930-50, which saw the flowering of city "boss" rule in Port Arthur under Mayor C. W. Cox (1934-49), and federal Liberal dominance by C. D. Howe and Rev. Dan Mclvor; (3) the postwar era (1950-70) of ethnic assimilation and broad ethnic participation at all levels of civic politics, and among all parties at the provincial and federal levels. Résumé La politique urbaine et l'ethnie on été intimement liées à l'histoire des villes jumelles de Port Arthur et de Fort William qui, plus tard, ont formé Thunder Bay en 1970. Le rapport historique entre l'expansion politique et urbaine et l'etnhie a pu être observé sur trois phases distinctes: 1) l'ère de l'exclusion ethnique et du factionnalisme pendant la period de 1900 à 1930, lorsque les groupes ethniques se sont établis dans des enclaves "étrangères" ou des "quartiers" et se sont grandement séparés des partis politiques populaires, surtout les groupes comme les Ukrainiens et les Finlandais qui prenaient une part active à la gauche radicale; 2) les duex décennies de protestation radicale et d'activisme ethnopolitique émergent de 1930 à 1950, qui ont observé la naissance de la règle municipale de "patron" à Port Arthur sous la direction du maire C. W. Cox (1934-49) et la dominance fédérale libérale de C. D. Howe et du Rév. Dan Mclvor; 3) l'ère d'après-guerre (1950-70) de l'assimilation ethnique et de la vaste participation ethnique à tous le échelons de la politique municipale et à tous les partis aux échelons provinciaux et fédéral.
Difficultés de transition au collégial : des politiques éducatives aux parcours des jeunes
Authors: Picard France , Kamanzi Pierre Canisius , Labrosse Julie 
Published: January 2014

L’entrée aux études collégiales n’est pas synonyme d’intégration et de réussite pour tous. Le présent article porte sur une population étudiante fragilisée, inscrite dans un dispositif de transition au cégep (la session d’accueil et d’intégration – SAI), pour qui la persévérance aux études est incertaine. Deux cohortes étudiantes (2009, n = 977 et 2010, n = 966) ont été suivies du secondaire jusqu’à dix-huit mois après leur entrée au cégep. L’enquête a permis de cerner la morphologie de parcours étudiants débutant par la SAI, en soulignant les difficultés particulières, mais aussi leur atténuation au fil du temps pour une certaine partie de cette population étudiante.
Le travail de rue : accompagner les jeunes au fil de leurs aléas existentiels et quotidiens
Authors: Fontaine Annie 
Published: January 2014

Après avoir posé un regard sur le besoin d’accompagnement social des jeunes plus ou moins en rupture sociale, l’article décrit comment les pratiques d’action communautaire en travail de rue permettent d’explorer « in situ » leur vie sociale et intime, puis de mettre en oeuvre un accompagnement modulé à leurs préoccupations et aspirations suivant les aléas de leur vie quotidienne ainsi que de leurs enjeux existentiels et sociaux. Cette réflexion souligne aussi les paradoxes de cette logique de l’accompagnement qui participe d’une tendance à l’individualisation de l’intervention et à l’instrumentalisation de la relation de proximité.

AbstractUsing a high‐speed optical imaging system specifically designed for observing the lightning attachment process, we have documented the process for stepped, dart, and dart‐stepped leaders in an anomalous rocket‐triggered lightning flash that terminated on a 10 m grounded utility pole. The initiation of the first return stroke was found to occur at a height of 23 ± 3 m above the top of the utility pole and was associated with three “slow front” dE/dt pulses. A time of 1.5 µs later, a fast rise in luminosity at 18 ± 2 m was associated with a “fast transition” dE/dt pulse. The first return stroke propagated bidirectionally from its initiation height, as did subsequent return strokes from their initiation heights of 8 ± 1 m to 16 ± 2 m above the top of the utility pole. The initial upward speed of the first return stroke was 1.4 × 108 m/s, while its initial downward speed was 2.2 × 107 m/s. The channel bottom luminosity of the first return stroke rose more slowly to a two or more times larger amplitude than that of the subsequent stroke luminosities. In contrast, the National Lightning Detection Network‐derived first‐return‐stroke peak current is smaller than that of the second and the third strokes, and our electric field records at 45 km show similar behavior for the initial field peaks of the first and subsequent strokes.

Published: January 2014

BackgroundThe need for objective assessment of patient outcomes is becoming an essential component of clinical practice for both private and academic otolaryngologists. The purpose of this study is to describe the implementation of an online model for collection of clinical outcomes data in patients with chronic rhinosinusitis (CRS).MethodsPatients completed the Sinonasal Outcome Test (SNOT‐22), Chronic Sinusitis Survey (CSS), and EuroQol 5‐dimension assessment (EQ‐5D), before and after sinus surgery. One year after initial patient enrollment, an online tool was developed to facilitate collection of postoperative data. Response rates preimplementation and postimplementation of online data collection were compared.ResultsA total of 520 sinus surgery patients provided outcomes data from the practices of 7 private practice (n = 308) and 4 academic otolaryngologists (n = 212). With implementation of the online collection instrument, the response rate at 3 months increased from 67% to 78.8% (p = 0.004). The overall follow‐up rate at 3 months was higher in patients recruited from private as compared to academic practices (77.9% vs 69.8%, respectively, p = 0.04).ConclusionQuality of life data can be effectively collected from CRS patients in both the private and academic practice setting. The addition of an online data collection tool can significantly increase response rates, and allow a comprehensive capture of meaningful clinical outcomes. Such a model is not difficult to implement and has increasing relevance as payers begin to request outcome data from providers.

Published: January 2014

BackgroundCells of the innate immune system that are implicated in allergy and immunity bind to chitin during tissue infiltration in a process negatively regulated by vertebrate chitinases. Both acidic mammalian chitinase (AMCase) and chitotriosidase (ChT) exert chitinolytic activity. The levels of activities of these enzymes in nasal polyps (NPs) of subjects who smoke or who suffer from allergies are unknown. In the present work, we measured the activities of AMCase and ChT in NPs of smokers and allergic subjects.MethodsWe report a prospective cohort study in a tertiary care facility. AMCase and ChT activities of NPs were measured in buffers of several pH values using the fluorogenic substrate 4‐methylumbelliferyl‐β‐d‐N,N′,N″‐triacetyl‐chitotriose.ResultsThe activities of AMCase and ChT in NPs did not differ significantly among smokers, nonsmokers, and ex‐smokers. AMCase and ChT activities were significantly higher in NPs of allergic subjects than in NPs of those who did not suffer from allergy.ConclusionIncreased levels of chitinolytic activities in NPs were associated with the allergic rhinitis. We suggest that control of such rhinitis may help to prevent the development and growth of NPs.
A computational exploration into isomorphously substituted effects on hydrogen electric field gradient and chemical shielding tensors in the H‐ZSM‐5 zeolite
Authors: Soltanali Saeed , Halladj Rouein , Ektefa Fatemeh 
Published: January 2014

ABSTRACTDensity functional theory calculations have been performed at the B3LYP/6‐31++G** level to investigate the effect of the isomorphously substituted ZSM‐5 zeolite with trivalent elements B, Al, and Ga on the hydrogen atom of the Brönsted acid site via nuclear quadrupole resonance (NQR) and nuclear magnetic resonance (NMR) parameters. ZSM‐5 clusters were modeled as ((H)3SiO)3–Si–O(H)–M–(OSi(H)3)3 (M = B, Al, and Ga). Variations of isotropic chemical shifts, δiso, of 1H atom in the Brönsted acid site as well as quadrupole coupling constant, CQ, and asymmetry parameter, ηQ, of 2H atom in the Brönsted acid site are well correlated with the trend in acidic strength of isomorphously substituted H‐ZSM‐5, estimated from the experimental results: B‐ZSM‐5 < Ga‐ZSM‐5 < Al‐ZSM‐5. The CQ value of 2H atom in the Brönsted acid site decreases in the order: B‐ZSM‐5, Ga‐ZSM‐5, Al‐ZSM‐5, respectively; eventually, their ηQ values of 2H atom in the Brönsted acid site increase concluding models with high CQ have a lower Brönsted acidity than those with low CQ. In addition, the calculated chemical shifts of the Brönsted proton increase in the sequence: B‐ZSM‐5 < Ga‐ZSM‐5 < Al‐ZSM‐5. All the results show a high consistency among NQR and NMR parameters and relative acidity of the isomorphously substituted ZSM‐5 zeolite. © 2014 Curtin University of Technology and John Wiley & Sons, Ltd.
Luminescent solid phase for sialic acid determination: a promising sensor for milk‐adulterated samples
Authors: de A. Alves Aline , Belian Mônica F. , Lavorante André F. 
Published: January 2014

ABSTRACTThis article presents the synthesis, characterization and spectroscopic study of silica modified with thenoyltrifluoroacetonate (SilTTA) and coordinated to an europium (III) ion, for the determination of sialic acid (NANA). Elemental analysis and infrared spectroscopy suggest silica functionalization, as well as coordination of beta‐diketone to the lanthanide ion. The emission spectra of compound‐free and coordinated Eu–SilTTA to NANA showed significant changes with respect to the maximum emission and spectral profile, suggesting that the NANA ion is coordinated to the Eu(III). The values of the phenomenological intensity parameters show an increase in polarizability around the Eu(III) in the case of Eu–SilTTA coordinated to NANA, as expected, since water molecules are less polarizable than sialic acid. The results of the batch assay showed that luminescent silica can be used for sialic acid determination in milk‐adulterated samples, with a correlation coefficient of 0.9992; and a detection limit of 0.4 mg/L; relative standard deviation (RSD%) = 0.0028.

Protonation of Pyridyl‐Substituted TTF Derivatives: Substituent Effects in Solution and in the Proton–Electron Correlated Charge‐Transfer Complexes

Published: January 2014

AbstractProtonated pyridyl‐substituted tetrathiafulvalene electron‐donor molecules (PyH+‐TTF) showed significant changes in the electron‐donating ability and HOMO–LUMO energy gap compared to the neutral analogues and gave a unique N+H⋅⋅⋅N hydrogen‐bonded (H‐bonded) dimer unit in the proton–electron correlated charge‐transfer (CT) complex crystals. We have evaluated these features from the viewpoint of the molecular structure of the PyH+‐TTF derivatives, that is, the substitution position of the Py group and/or the presence or absence of the ethylenedithio (EDT) group. Among 2‐PyH+‐TTF (1 oH+), 3‐PyH+‐TTF (1 mH+), 4‐PyH+‐TTF (1 pH+), and 4‐PyH+‐EDT‐TTF (2 pH+) systems, the para‐pyridyl‐substituted donors 1 pH+ and 2 pH+ exhibit more marked changes upon protonation in solution; a larger redshift in the intramolecular CT absorption band and a larger decrease in the electron‐donating ability. Furthermore, the EDT system 2 pH+ has the smallest intramolecular Coulombic repulsion energy. These differences are reasonably interpreted by considering the energy levels and distributions of the HOMO and LUMO obtained by quantum chemical calculations. Such substituent effects related to protonation were also examined by comparing the structure and properties of a new H‐bonded CT complex crystal based on 2 pH+ with those of its 1 pH+ analogue recently prepared by us: Both of them form a similar type of H‐bonded dimer unit, however, its charge distribution as well as the overall molecular arrangement, electronic structure, and conductivity were significantly modulated by the introduction of the EDT group. These results provide a new insight into the structural and electronic features of the PyH+‐TTF‐based proton–electron correlated molecular conductors.
Topotactic Conversion of β‐Helix‐Layered Silicate into AST‐Type Zeolite through Successive Interlayer Modifications

Published: January 2014

AbstractAST‐type zeolite with a plate morphology can be synthesized by topotactic conversion of a layered silicate (β‐helix‐layered silicate; HLS) by using N,N‐dimethylpropionamide (DPA) to control the layer stacking of silicate layers and the subsequent interlayer condensation. Treatment of HLS twice with 1) hydrochloric acid/ethanol and 2) dimethylsulfoxide (DMSO) are needed to remove interlayer hydrated Na ions and tetramethylammonium (TMA) ions in intralayer cup‐like cavities (intracavity TMA ions), both of which are introduced during the preparation of HLS. The utilization of an amide molecule is effective for the control of the stacking sequence of silicate layers. This method could be applicable to various layered silicates that cannot be topotactically converted into three‐dimensional networks by simple interlayer condensation by judicious choice of amide molecules.
