Published: June 2013

Aim and objectivesTo assess the construct validity and reliability of the Brazilian Portuguese versions of the 29‐ and 13‐item scales of the Antonovsky's Sense of Coherence Scale (SOC‐29 and SOC‐13).BackgroundAntonovsky's Sense of Coherence Questionnaire was developed to measure the main construct of the salutogenic theory, the sense of coherence. The use of the sense of coherence by health professionals might help identifying specific coping strategies used by person with chronic illness.DesignCross‐sectional study.MethodsThe SOC‐29 has been culturally adapted to Brazilian Portuguese language. In this study, we assessed its psychometric properties (construct validity and internal reliability) tested on 203 cardiac patients. The SOC‐13 was tested on another 100 cardiac patients hospitalised in the same hospital. The construct validity of both versions was investigated through Pearson correlation between the measures of sense of coherence and of correlated constructs (self‐esteem, depression and age), analysis of the principal components and comparison of distinct groups (male vs. female). The internal reliability for both versions was evaluated by Cronbach's alpha.ResultsFor both versions, the construct validity assessments showed strong positive correlations between sense of coherence and self‐esteem and strong negative correlations between sense of coherence and depression (convergent validity), and weak correlation between sense of coherence and age (divergent validity). Principal component analysis supported in part the presence of a single component (unidimensionality). Differences in sense of coherence were found by sex with SOC‐29, but not with SOC‐13. Cronbach's alpha coefficients showed satisfactory internal consistency in both versions.ConclusionsThe Brazilian Portuguese versions of SOC‐29 and SOC‐13 can be considered valid and reliable for the populations studied. More studies need to be performed to assess these proprieties in other Brazilian populations.Relevance to clinical practiceThis scale can be used in research and clinical practice in Brazil to assess nursing interventions aimed at decreasing stress during cardiac rehabilitation.
Moving beyond the therapeutic relationship: a selective review of intimacy in the sexual health encounter in nursing practice
Authors: East Leah , Hutchinson Marie 
Published: June 2013

Aims and objectivesFor the purposes of this study, a selective review of the literature was undertaken with the aim of examining nurses' preparedness to engage in intimate interactions within the context of sexual health care. Kirk's (2007) model of interactional intimacy is used as a lens to examine the literature.BackgroundThe provision of sexual health care is often a neglected area of nursing care despite being recognised as a component of holistic nursing practice. Despite theoretical discussion about various forms of intimacy and intimate care, there has been little examination of the interface between intimacy and sexual health care that usefully informs practice.DesignSelective review and synthesis of the literature.ConclusionThe literature of humanistic interpretations of caring that has dominated nursing discourse over the last half‐century has limited progress on defining and developing forms of clinical interaction that are suited to promoting nurses engagement in sexual health care. We propose that Kirk's model has useful utility in preparing nurses to engage more readily with sexual health care as a routine component of their practice.Relevance to clinical practiceSexual health adversity can often accompany ill health, and therefore, the provision of appropriate care is required to negate detrimental outcomes and promote positive well‐being. Although sexual health care is often not prioritised in practice, nurses are in a prime position to promote sexual health care and well‐being. By conducting sexual health assessments and providing sexual health care routinely, the gap that exists between patients' sexual healthcare needs and the lack of sexual health care provided can be minimised.
Allegories of the End: Classical Sociologies of Economic Sustainability and Cultural Ruin
Authors: Kemple Thomas 
Published: June 2013

AbstractAgainst the backdrop of contemporary discourses of “sustainable growth” and “cultures of waste”, this essay considers the arguments of early sociologists concerning the relationship between subsistence economies of reproduction and sacrificial economies of symbolic exchange. In the first few decades of the twentieth century, Marcel Mauss and Thorstein Veblen each formulated influential accounts of the social barriers and physical limits to human life which find an echo in later cultural theories concerning economies of excess and overproduction in (post)modern societies. Rather than assess the empirical validity or theoretical accuracy of these arguments, this essay examines how factual descriptions of excess and decay can be read as sociological allegories of a world in ruins. The model for such a reading can be found in the work of another sociological classic, Georg Simmel, whose systematic account of the self‐preservation and expansion of social groups anticipates his later more impressionistic and fragmentary reflections on “the tragedy of culture”, understood as a struggle for individual autonomy against social and natural forces of objectification. Simmel and his classical contemporaries thus anticipate later thinkers who ask whether “the end of an era” should be understood as a terminal point, an ideal purpose, or a cyclical stage in the “progress” of history.
Categorizing Categorization Research: Review, Integration, and Future Directions
Authors: Vergne J.‐P. , Wry Tyler 
Published: June 2013

AbstractThis paper offers a systematic review of the literature on organizational categories and categorization published in the last 14 years (1999–2012). After identifying a core of roughly 100 papers on categories that appeared in management, organization, and sociology journals, we classified them based on several key dimensions, and analysed a few trends within the categorization literature. Our most surprising finding may be the fact that until recently, there was no mutual recognition of the existence of a distinct ‘literature on categories’ despite the wealth of published material on the topic. After summarizing some core theoretical features of that emergent literature, we propose integrative definitions of its core constructs and suggest several areas of research that could further enrich it in the future.
Angiographic Lumen Changes Associated with Oversized Intracranial Stent Implantation for Aneurysm Treatment

Published: June 2013

ABSTRACTBACKGROUNDThe effect of oversized intracranial stent implantation, and potential excessive neointimal hyperplasia from the chronic outward radial force, has not been reported. We sought to compare the angiographic narrowing associated with implantation of oversized stents.METHODSWe reviewed an aneurysm database and identified patients treated with stent‐assisted embolization involving a vessel size transition. Demographics and lesion characteristics were extracted. The relationship between lumen diameter and stent oversizing was compared.RESULTSTwenty vessels were identified in 18 patients, providing 80 paired data points. Mean follow‐up time was 8 months (SD 6). The average oversizing in the smaller diameter parent vessel landing‐zone was 1.75 mm. Mean change in lumen size from pre‐stent implantation was not significantly different for any of the four sites. There was a significant difference in change of lumen size at the stent tines when compared with the respective mid‐stent segment for both the proximal (P = 0.02) and distal (P = 0.0004) landing zones.CONCLUSIONSA small significant lumen loss occurs at stent tines when compared to midstent struts. However, there is no overall significant stenosis from highly oversized stents. Persistent luminal gain from the oversized stent radial force likely predominates over any neointimal hyperplasia.

Published: June 2013

AimsTo assess the awareness of hepatitis C virus (HCV) infection status in a high‐risk population.MethodsA targeted population survey of clients of methadone maintenance clinics in metropolitan and rural New South Wales, using an interviewer‐administered face‐to‐face questionnaire. Main outcome measures include awareness of HCV status, time elapsed since last tested and children's HCV status.ResultsA total of 329 clients completed the survey, of which 97% perceived to have been tested for HCV in the past. One hundred and seventy (52%) participants considered themselves to be negative for HCV. Of these the median time since last tested was 2 years (2 weeks–25 years). Although 94% of all parents believed that their child's HCV status was negative, only 49% of respondents stated that their children had been tested for HCV. Voluntary testing was offered to all clients and their children with only one accepting.ConclusionsAwareness of HCV infection status in this high‐risk population is suboptimal. This indicates that existing educational strategies are inadequate and that there is a disconnect between their health needs and the medical care they receive. Novel approaches need to be considered to improve the knowledge of HCV transmission and hopefully improve HCV‐associated health outcomes in high‐risk populations.
Detection of Plant Pathogen Spores of Economic Significance on Pollen Trap Slides
Authors: Brittain Ian , Selby Katherine , Taylor Moray , Mumford Rick 
Published: June 2013

AbstractReal‐time polymerase chain reaction (PCR) assays were used to evaluate a small number of samples from a volumetric spore trap normally used for counting pollen grains. Samples from a total of 6 days during July and August 2011 were screened. Pathogen DNA was detected from three of four groups of economically significant plant pathogens for which real‐time PCR assays were available. These were Tilletia spp. on 1 day, Puccinia spp. on 2 days and Fusarium spp. on all 6 days. No amplification of real‐time PCR assays was detected for Phytophthora infestans or P. ramorum. The results indicate that plant pathogens can be detected in air sampling networks, which are remote from arable cropping and deployed for other purposes. This has implications for rapidly identifying periods of pathogen dispersal and improving the accuracy of information on pathogen spore load in the atmosphere.

Background and ObjectiveAtorvastatin (ATV) has bone anabolic properties, and alendronate (ALD) is an important antiresorptive drug. This study aimed to evaluate the effects of the combination of ALD and ATV on ligature‐induced alveolar bone loss in rats.Material and MethodsPeriodontitis was induced by ligature in 78 Wistar rats. Groups of six rats prophylactically received 0.9% saline (SAL), ALD (0.01 or 0.25 mg/kg subcutaneously) or ATV (0.3 or 27 mg/kg by gavage). Then, groups of six rats received the combination of ALD+ATV (0.25 mg/kg + 27 mg/kg, 0.01 mg/kg + 0.3 mg/kg, 0.25 mg/kg + 0.3 mg/kg or 0.01 mg/kg + 27 mg/kg) prophylactically. An extra group of six rats received therapeutic SAL or a lower‐dose combination of ALD+ATV (0.01 mg/kg + 0.3 mg/kg, respectively) therapeutically. Three extra groups of six rats each received SAL or a lower‐dose combination of ALD+ATV (0.01 mg/kg + 0.3 mg/kg, respectively) prophylactically or therapeutically for histometric and immunohistochemical analyses. The rats were killed on day 11 after ligature placement, and the maxillae were removed and processed for macroscopic, histomorphometric and TRAP immunohistochemical analyses. Gingival samples were collected to evaluate myeloperoxidase (MPO) activity. Blood samples were collected to measure serum bone‐specific alkaline phosphatase (BALP) and transaminase levels and for hematological studies. Rats were weighed daily.ResultsAll combined therapies prevented alveolar bone loss when compared with SAL or low doses of monotherapy (ALD or ATV) (p < 0.05). The lower‐dose combination of ALD+ATV (0.01 mg/kg + 0.3 mg/kg, respectively), administered either prophylactically (39.0%) or therapeutically (53.5%), prevented alveolar bone loss. Decreases in bone and cementum resorption, in leukocyte infiltration and in immunostaining for TRAP and MPO activity corroborated the morphometric findings. The lower‐dose combination of ALD+ATV (0.01 mg/kg + 0.3 mg/kg, respectively) prevented BALP reduction (p < 0.05) and did not alter the level of serum transaminases. Moreover, the lower‐dose combination of ALD+ATV (0.01 mg/kg + 0.3 mg/kg, respectively) also reduced neutrophilia and lymphomonocytosis and did not cause weight loss when compared with administration of SAL.ConclusionThe lower‐dose combination of ALD+ATV (0.01 mg/kg + 0.3 mg/kg, respectively) demonstrated a protective effect on alveolar bone loss.
Nucleotide diversity of 11S seed storage protein gene and its implications for ecological adaptation of Oryza nivara

Published: June 2013

AbstractThe mechanism by which a new species arises and adapts to its environment is a fundamental question in evolutionary biology. Seed characteristics such as seed size and nutrient composition are important fitness‐related traits and have been shown to vary greatly among populations and species. However, the significance of variation in seed traits in plant adaptation and speciation remains unclear. We carried out a population genetic study on nucleotide variation of one 11S seed storage protein gene (Pss) of Oryza rufipogon Griff. and O. nivara Sharma & Shastry, two closely related wild rice species. By comparatively examining the genetic variation pattern of the regulatory and coding regions of Pss and fragments of six reference loci across different chromosomes, we found significantly lower polymorphisms at coding regions of the gene (PssI) in O. nivara relative to O. rufipogon. Neutrality tests indicated that the reduction of polymorphisms at PssI in O. nivara was caused by positive selection rather than population demography, implying a role of selection on the 11S seed protein gene. Further phylogenetic and principal component analyses also support the hypotheses that the origin of O. nivara was associated with the adaptive divergence on the coding region of Pss. It is most likely that higher reproductive effort would be favored when O. nivara arose from O. rufipogon populations and adapted to the environment change.
Overview of the morphology, anatomy, and ontogeny of Adiantum capillus‐veneris: An experimental system to study the development of ferns

Published: June 2013

AbstractAdiantum capillus‐veneris L., commonly regarded as a good experimental plant for the study of fern development, is investigated, and its life cycle under laboratory conditions is described. In our study, the life cycle of A. capillus‐veneris was completed in 100 days. Features of spore germination, antheridium and archegonium ontogeny and development, and embryogenesis are investigated. Exosporic gametophytes of A. capillus‐veneris came from spores, and ended with the cordate prothallia. Antheridia and archegonia were generally situated toward the posterior end and the notch of the prothallia, respectively. Sporophyte was also studied with emphasis on leaf morphology and the vascular system. There were vascular bundles of dictyostele without secondary vascular tissues. Sporogenesis was scrutinized from sporangial initial of a single surface cell to the annulus shedding spores explosively. Our findings provide insight into the life cycle of the leptosporangiate ferns under experimental conditions, and make it possible for A. capillus‐veneris to be an underlying model plant for the study of evolutionary and developmental biology.

Published: June 2013

AbstractBranches and leafy shoots of fossil Glyptostrobus Endlicher (Cupressaceae s.l.), preserved as compressions of leaf cuticle with stomata and a single scale of a seed cone, have been found for the first time in the Jijuntun Formations of the Eocene in Fushun, Liaoning Province, NE China. These fossil remains are identified as Glyptostrobus by comparing them with Sequoia, Metasequoia, and Taxodium, which are commonly in association and have similar morphological features. The fossil remains are assigned to Glyptostrobus based on characters of leaf morphotypes, phyllotaxis, leaf apex, leaf base, epidermal cell morphology, orientation of stomata, and a single flabellate ovuliferous scale of a seed cone. All of the characteristics of the fossil remains are in agreement with those of the diagnosis of G. europaeus (Brongn.) Ung. These newly described Glyptostrobus specimens from China represent linear, linear‐subulate, and scale‐like leaves. The species G. europaeus is common for Eurasia where it has a wide geographic and stratigraphic range, but the cuticle characteristics of the species are rarely reported. In China, fossil remains of G. europaeus have been found in the provinces of Heilongjiang, Jilin, Liaoning, Xinjiang, Yunnan, and Hong Kong.

SummaryHuman APOBEC3 (A3) cytosine deaminases are antiviral restriction factors capable of editing the genome the hepatitis B virus (HBV). Despite the importance of the human A3 protein family for the innate immune response little is known about the clinical relevance for hepatitis B. The aim of this study was to utilize ultra‐deep pyrosequencing (UDPS) data to analyse the phenomenon of G‐to‐A hypermutation of the complete HBV genome and to relate it to fundamental characteristics of patients with chronic hepatitis B. By analysing the viral population of 80 treatment naïve patients (47 HBeAg‐positive and 33 HBeAg‐negative), we identified an unequal distribution of G‐to‐A hypermutations across the genome. Our data indicate that G‐to‐A hypermutation occurs predominantly in a region between nucleotide positions 600 and 1800 a region which is usually single stranded in matured HBV particles. This implies that A3 likely edits HBV in the virion. Hypermutation rates for HBeAg‐negative patients were more than 10‐fold higher than those of HBeAg‐positive patients. For HBeAg‐negative patients higher hypermutation rates were significantly associated with the degree of fibrosis. Additionally, we found that for HBeAg‐positive chronic hepatitis G‐to‐A hypermutation rates were significantly associated with the relative prevalence of the G1764A mutation, which is related to HBeAg seroconversion. In total, our data imply an important association of hypermutation mediated by A3 deaminases with the natural progression of chronic hepatitis B infections both in terms of HBeAg seroconversion and disease progression towards cirrhosis.
On the importance of edaphic variables to predict plant species distributions – limits and prospects
Authors: Thuiller Wilfried 
Published: June 2013

AbstractAlthough the importance of edaphic parameters on plant growth and survival is known, they are rarely incorporated as predictors in plant species distribution models (SDM). Dubuis et al., in this issue, show they may improve the performance of plant SDMs in Alpine ecosystems. This paves the way for more comprehensive assessments of the value of including edaphic variables into SDMs.
Receptors and mechanisms mediating the biphasic response evoked by bradykinin in rat colonic smooth muscle
Authors: Würner L. , Diener M. 
Published: June 2013

AbstractBackgroundIn rat duodenum, bradykinin induces a relaxation followed by a contraction. Different types of ion channels and receptors as well as non‐muscle cells have been suggested to be involved in this response. As it is unclear whether these changes are observed also in rat large intestine and the mechanisms which might underlie this response, the effect of bradykinin on rat colonic motility was tested.MethodsIsometric contractions were measured on full‐thickness preparations or preparations, from which individual layers had been dissected. The expression of bradykinin receptors was analyzed by immunohistochemistry and RT‐PCR. Isolated intestinal muscle cells were investigated with Ca2+‐imaging techniques.Key ResultsBradykinin caused a biphasic contractile response (initial relaxation followed by contraction) in rat colon, which was resistant against tetrodotoxin. The kinin‐induced relaxation was inhibited by tetrapentylammonium chloride, a blocker of Ca2+‐activated K+ channels. Des‐arg9‐bradykinin did not induce any effect on the native colon, although after 5 h in vitro preincubation, a contractile response was evoked by this B1 receptor agonist. The consecutive ablation of adherent layers of the intestinal wall strongly reduced the response to bradykinin in comparison with a control stimulus, i.e., carbachol, suggesting a contribution of non‐muscle cells in the mediation of this response.Conclusions & InferencesBradykinin induced a biphasic change in contractility in the rat colon. In the native intestine, only the B2 receptor is involved in this effect. Neighboring cell obviously sensitize the smooth muscle to the stimulation of these receptors.

AbstractThis article reports the case of a large aneurysmal bone cyst (ABC) in a 12‐year‐old girl, who came to the Ophir Loyola Hospital (Belém, Pará, Brazil) complaining of pain and debilitated because of a secondary infection. Radiographic and tomographic findings presented an expansion/destruction pattern, including a slight narrowing of the oropharynx and destruction of the right mandibular condyle and coronoid process, which according to the literature are rarely affected by this type of cyst. Because of the size and progression of the cyst, the treatment included block resection with a costochondral rib graft. The clinical and radiographic aspects of expansion with destruction, associated with trans‐surgical moderate bleeding and the histopathological findings (dense connective tissue and numerous blood spaces) led to a final diagnosis of a mixed type ABC.
