Lymphoid Proliferations Associated With Human Immunodeficiency Virus Infection
Authors: Chadburn Amy , Abdul-Nabi Anmaar M. , Teruya Bryan Scott , Lo Amy A. 
Published: March 2013

Context.—Individuals who are immune deficient are at an increased risk for developing lymphoproliferative lesions and lymphomas. Human immunodeficiency virus (HIV) infection is 1 of 4 clinical settings associated with immunodeficiency recognized by the World Health Organization (WHO) in which there is an increased incidence of lymphoma and other lymphoproliferative disorders.Objectives.—To describe the major categories of benign lymphoid proliferations, including progressive HIV-related lymphadenopathy, benign lymphoepithelial cystic lesions, and multicentric Castleman disease, as well as the different types of HIV-related lymphomas as defined by the WHO. The characteristic morphologic, immunophenotypic, and genetic features of the different entities will be discussed in addition to some of the pathogenetic mechanisms.Data Sources.—The WHO classification of tumors of hematopoietic and lymphoid tissues (2001 and 2008), published literature from PubMed (National Library of Medicine), published textbooks, and primary material from the authors' current and previous institutions.Conclusions.—HIV infection represents one of the clinical settings recognized by the WHO in which immunodeficiency-related lymphoproliferative disorders may arise. Although most lymphomas that arise in patients with HIV infection are diffuse, aggressive B-cell lesions, other lesions, which are “benign” lymphoid proliferations, may also be associated with significant clinical consequences. These lymphoproliferations, like many other immunodeficiency-associated lymphoproliferative disorders, are often difficult to classify. Studies of HIV-associated lymphoid proliferations will continue to increase our understanding of both the immune system and lymphomagenesis.

Authors: Hanson Joshua Anspach , Ason Regina , Weinreb Jeffrey , Van Dyke Alison , Mitchell Kisha Anne 
Published: March 2013

Context.—No study has evaluated radiology/pathology correlation of percentage viable tumor (PVT) estimates in ablated hepatocellular carcinoma (HCC) to examine the reliability of radiologic estimates.
Objective.—To determine how well interdisciplinary PVT estimates correlate and identify pathologic factors that influence this correlation.
Design.—Pathologists and radiologists established blinded PVT estimates in 22 HCC ablation cavities. Paired sample t tests examined the differences between the interdisciplinary estimates.
Results.—Fifteen cavities had pathologic viable tumor (VT) (68%) and 6 had radiographic VT (22%). Radiology's sensitivity for detecting VT was 40% and the specificity was 100%. Pathology detected significantly more VT than radiology (pathology mean = 22.3% versus radiology mean = 2.6%; P = .005). Five cavities had tumor growth in a discontinuous rim pattern, 7 in a nodular pattern, and 3 in a solid pattern. Radiology did not detect VT in cavities with a discontinuous rim pattern (sensitivity = 0%) but did detect VT in 3 cavities with a nodular pattern (sensitivity = 43%), and in all cavities with a solid pattern (sensitivity = 100%). There was no significant difference in PVT estimates in cavities 3.5 cm or larger (P = .07), but there was a significant difference in cavities smaller than 3.5 cm (P = .01).
Conclusion.—This study clarifies that the risk of underestimation by imaging is greatest in small lesions (&lt;3.5 cm), though the sensitivity of detection depends primarily on the tumor growth pattern within the cavity. This underestimation raises the question of whether basing treatment decisions on a radiologic impression of complete ablation is valid.
Le magazine canadien-français : un média américain ?
Authors: Saint-Jacques Denis , des Rivières Marie-José 
Published: March 2013

L’article examine la qualification d’« américain » donnée au magazine canadien-français du premier tiers du xxe siècle. Si l’opinion des contemporains et la présentation matérielle apparaissent comme des indices en ce sens, une comparaison avec les formes dominantes des magazines français et américains de la même époque révèle aussi un critère « d’esprit » qui confirmerait la justesse de cette appréciation. Pourtant, un autre aspect fondamental, le contenu de fiction, s’affirme absolument français et conduit à réévaluer l’américanité de ce média.
Un valentin au grand Maurice — Léon Bloy, Olivar Asselin et Robert LaPalme : essai sur un problème de transfert culturel dans l’histoire de la caricature au Québec
Authors: Hardy Dominic 
Published: March 2013

En partant d’une caricature remarquablement violente de Maurice Duplessis, dessinée par Robert LaPalme et publiée dans l’hebdomadaire Vrai en février 1958, la présente étude fait état de certains défis que posent l’analyse et l’interprétation de l’image satirique dans l’histoire et, plus généralement, dans l’histoire de la culture littéraire et artistique au Québec. Les recherches sur la carrière de LaPalme montrent l’importance qu’il faut accorder à son milieu intellectuel et idéologique, de par son association avec quelques-uns des plus influents journalistes-éditeurs de son temps. Or une figure surprenante émerge de ces recherches : celle de l’écrivain français Léon Bloy. Les traces de son influence semblent nombreuses mais demeurent difficiles à dégager. Nous croyons pourtant qu’il s’agit bel et bien d’un cas de transfert culturel qui s’opère depuis la littérature polémique bloyenne du tournant du xxe siècle vers cette autre littérature polémique, souvent illustrée, qui est pratiquée au Québec dans les années 1930-1950 par les Olivar Asselin, Claude-Henri Grignon, André Laurendeau et, bien entendu, Robert LaPalme.
Les sites Internet des conseils scolaires francophones canadiens en milieu minoritaire : ressources indispensables pour les couples mixtes (interlinguistiques / interculturels)
Authors: Rocque Jules 
Published: March 2013

L’article présente les résultats d’une cueillette de données virtuelles (2008 et 2010) à partir d’un échantillon de sites Internet de la Fédération nationale des conseils scolaires francophones (FNCSF). À la lumière de la transformation du profil de la clientèle qui fréquente les écoles de langue française en milieu francophone minoritaire (63 % provenant de couples mixtes ayant l’anglais comme langue de fonctionnement), l’étude cherche à voir quelle place occupe la langue anglaise dans les sites Internet et, plus particulièrement, quel type d’information est disponible pour les parents qui ne parlent pas le français. Malgré une certaine amélioration dans l’information disponible en anglais, l’auteur propose des recommandations qui pourraient améliorer la communication entre les autorités scolaires et leur clientèle.
Pneumoconiosis and malignant mesothelioma in a family operated metal casting business that used industrial talc from New York state
Authors: Finkelstein Murray M. 
Published: March 2013

AbstractBackgroundThe United States is second only to the People's Republic of China in annual talc production. U.S. talc is used in the production of ceramics, paint, paper, plastics, roofing, rubber, cosmetics, flooring, caulking, and agricultural applications. A number of U.S. talc deposits consistently contain talc intergrown with amphiboles such as tremolite and/or anthophyllite. It has long been recognized that miners and millers of talc deposits are at risk for pneumoconiosis and it has recently been reported that it is prudent, on the balance of probabilities, to conclude that dusts from New York State talc ores are capable of causing mesothelioma in exposed workers. This is a report of the diagnosis of pneumoconiosis and mesothelioma in a husband and wife who operated a small metal casting business that used industrial talc from New York as a parting agent.MethodsCase reports, including medical records and exposure histories, were provided by an attorney who had also commissioned laboratory investigation of the industrial talc product used in the factory.ResultsMrs X was diagnosed with pneumoconiosis characterized by interstitial fibrosis and heavily calcified pleural plaques. Mr X had calcified pleural plaques and developed a fatal pleural mesothelioma. Samples of the industrial talc contained fibrous tremolite and anthophyllite.ConclusionsThe author concludes that end users of industrial talc from New York State may be at risk of pneumoconiosis and malignant disease. End users of talcs from other regions of the United States, where talc formation arose from processes driven by regional metamorphism, might also be at risk. Am. J. Ind.

Published: March 2013

AbstractBackgroundIn 2000, a manufacturer of beryllium materials and products introduced a comprehensive program to prevent beryllium sensitization and chronic beryllium disease (CBD). We assessed the program's efficacy in preventing sensitization 9 years after implementation.MethodsCurrent and former workers hired since program implementation completed questionnaires and provided blood samples for the beryllium lymphocyte proliferation test (BeLPT). Using these data, as well as company medical surveillance data, we estimated beryllium sensitization prevalence.ResultsCross‐sectional prevalence of sensitization was 0.7% (2/298). Combining survey results with surveillance results, a total of seven were identified as sensitized (2.3%). Early Program workers were more likely to be sensitized than Late Program workers; one of the latter was newly identified. All sensitization was identified while participants were employed. One worker was diagnosed with CBD during employment.ConclusionsThe combination of increased respiratory and dermal protection, enclosure and improved ventilation of high‐risk processes, dust migration control, improved housekeeping, and worker and management education showed utility in reducing sensitization in the program's first 9 years. The low rate (0.6%, 1/175) among Late Program workers suggests that continuing refinements have provided additional protection against sensitization compared to the program's early years. Am. J. Ind.

AbstractBackgroundRespiratory tract‐related occupational disability is common among adults of working age. We examined occupational vapors, gas, dust, or fume (VGDF) exposure as a predictor of disability, based on respiratory sickness absence among the actively employed, at an early point at which prevention may be most relevant.MethodsCurrently employed European Community Respiratory Health Survey II participants (n = 6,988) were classified into three mutually exclusive, condition/symptom‐based categories: physician‐diagnosed asthma, self‐reported rhinitis, and wheeze/breathlessness (n = 4,772). Logistic regression analysis estimated the odds of respiratory sickness absence (past 12 months) by VGDF exposure.ResultsIn the condition/symptom groups, 327 (6.9%) reported respiratory sickness absence. Exposure to VGDF was associated with increased odds of respiratory sickness absence: asthma odds ratio [OR] 2.0 (95% confidence interval [CI] 1.1–3.6), wheeze/breathlessness OR 2.2 (95% CI 1.01–4.8); rhinitis OR 1.9 (95% CI 1.02–3.4).ConclusionOne in 15 currently employed with asthma, breathlessness, or rhinitis reported respiratory sickness absence. VGDF exposure doubled the odds of respiratory sickness absence, suggesting a focus for disability prevention. Am. J. Ind. Med. 56:541–549, 2013. © 2013 Wiley Periodicals, Inc.
Dominance style of female white‐faced capuchins
Authors: Bergstrom Mackenzie L. , Fedigan Linda M. 
Published: March 2013

ABSTRACTDominance style, the level of tolerance displayed by dominant individuals toward subordinate ones, is exhibited along a continuum from despotic to relaxed. It is a useful concept to describe the nature of dominance relationships in macaque species and it bridges among multiple features of dominance hierarchies, aggression, kinship and conflict resolution. Capuchins share many behavioral similarities with Old World monkeys and like macaques, may exhibit a suite of covarying characteristics related to dominance. Here, we provide an assessment of dominance style by examining measures of aggression and kin bias in 22 adult female white‐faced capuchin monkeys (Cebus capucinus) in three social groups at Santa Rosa Sector, Costa Rica. We found that bidirectionality of aggression was low (mean = 6.9% ± SE 1.6). However, there were few significant correlations between kin relatedness and social behavior (approaching, grooming, proximity, and co‐feeding), even though the intensity of kin bias in grooming was moderate and higher in the larger group. We conclude that patterns of aggression and kin‐biased behavior in our study animals are dissimilar to the patterns of covariation observed in macaque species. While unidirectional aggression suggests a despotic dominance style, the moderate expression of kin bias suggests an intermediate to relaxed classification when compared with results from an analysis of 19 macaque species. Additional studies of capuchin species and behaviors associated with dominance style (i.e., conciliatory tendencies) would help to create a comparative framework for the genus Cebus, and allow for more detailed cross‐species comparison of dominance relationships across all primates.

Antibacterial antiadhesion membranes from silver‐nanoparticle‐doped electrospun poly(L‐lactide) nanofibers

Published: March 2013

AbstractElectrospun fibrous membranes have been used frequently in biomedical applications, but their simultaneous use as antibacterial agents and in the prevention of cell adhesion on repaired tendons after injury has not been investigated. In this study, silver‐nanoparticle (SN)‐loaded poly(L‐lactide) (PLLA) fibrous membranes were prepared by the electrospinning of SNs into PLLA fibers. Micrograph results showed that these membranes were composed of electrospun fibers and that the fibers were incorporated with SNs. From the results of X‐ray diffraction and thermogravimetry, we concluded that the SNs were physically mixed into the fibers at the desired content. The mechanical properties were not significantly changed. The preliminary antibacterial effects on Staphylococcus epidermidis and Staphylococcus aureus and the synergistic antiproliferative effects of the SN‐loaded PLLA fibrous membranes were observed. Taken together, these results demonstrate that SNs can be directly loaded onto a biodegradable PLLA fibrous membrane via electrospinning to achieve proper material properties with preliminary potential as antibacterial antiadhesion barriers for tendon injury. © 2013 Wiley Periodicals, Inc.

d‐penicillamine capped cadmium telluride quantum dots as a novel fluorometric sensor of copper(II)
Authors: Mohammad‐Rezaei Rahim , Razmi Habib , Abdolmohammad‐Zadeh Hossein 
Published: March 2013

ABSTRACTd‐penicillamine‐capped cadmium telluride quantum dots (DPA‐capped CdTe QDs) were synthesized as the new fluorescent semiconductor nanocrystal in aqueous solution. Fourier transmission infrared spectroscopy, X‐ray diffraction, transmission electron microscopy, ultraviolet‐visible and photoluminescence spectroscopy were used for characterization of the QDs. Based on the quenching effect of Cu2+ ions on the fluorescence intensity of DPA‐capped CdTe QDs, a new fluorometric sensor for copper(II) detection was developed that showed good linearity over the concentration range 5 × 10–9–3 × 10–6 m with the detection limit 0.4 × 10–9 m. Owing to the strong affinity of the DPA to copper(II), the sensor showed appropriate selectivity for copper(II) compared with conventional QDs. The DPA‐capped CdTe QDs was successfully applied for determination of Cu2+ concentration in river, well and tap waters with satisfactory results. Copyright © 2013 John Wiley & Sons, Ltd.
Steric Control in the π‐Dimerization of Oligothiophene Radical Cations Annelated with Bicyclo[2.2.2]octene Units

Published: March 2013

AbstractA Two series of oligothiophenes 2(nT) (n=4,5), annelated with bicyclo[2.2.2]octene (BCO) units at both ends, and quaterthiophenes 3 a–c, annelated with various numbers of BCO units at different positions, were newly synthesized to investigate the driving forces of π‐dimerization and the structure–property relationships of the π‐dimers of oligothiophene radical cations. Their radical‐cation salts were prepared through chemical one‐electron oxidation by using nitrosonium hexafluoroantimonate. From variable‐temperature electron spin resonance and electronic absorption measurements, the π‐dimerization capability was found to vary among the members of the 2(nT)+.SbF6− series and 3+.SbF6− series of compounds. To examine these results, density functional theory (DFT) calculations at the M06‐2X/6‐31G(d) level were conducted for the π‐dimers. This level of theory was found to successfully reproduce the previously reported X‐ray structure of (2(3T))22+ having a bent π‐dimer structure with cis–cis conformations. The absorption bands obtained by time‐dependent DFT calculations for the π‐dimers were in reasonable agreement with the experimental spectra. The attractive and repulsive forces for the π‐dimerization were divided into four factors: 1) SOMO–SOMO interactions, 2) van der Waals forces, 3) solvation, and 4) Coulomb repulsion, and the effects of each factor on the structural differences and chain‐length dependence are discussed in detail.
