Published: August 2012

AbstractThis study compared the susceptibility of three blue catfish strains (D&B, USDA 101 and USDA 102) to the parasite Ichthyophthirius multifiliis (Ich). In Trial I, a cohabitation study (all strains stocked communally) was conducted and fish were exposed to theronts at 0, 200, 1000, 5000 or 25 000 theronts fish−1, respectively. All fish died when exposed to theronts at 5000 or 25 000 theronts fish−1. When exposed to 1000 theronts fish−1, USDA 102 strain of blue catfish showed significantly lower mortality (78.5%) compared to USDA 101 and D&B strains (92.7% and 100%). In Trial II, the same three strains of blue fish were evaluated for their susceptibility to Ich with strains challenged in separate tanks by adding Ich theronts at 0, 200 and 1000 theronts fish−1, respectively. All D&B and USDA 101 blue catfish died; however, 42.3% of USDA 102 strain survived the infection when exposed to 1000 theronts per fish. The results indicate that there are differences among strains of blue catfish for susceptibility to Ich, and these differences will be useful in the development of improved catfish germplasm for commercial aquaculture.

Published: August 2012

AbstractBackground  Telangiectasia macularis multiplex acquisita (TMMA) is a rarely documented entity with distinctive clinical manifestation. Most patients are middle‐aged adults. It may be associated with other diseases such as hepatitis, diabetes, or cardiovascular diseases.Objectives  To assess the clinical presentation of TMMA and its association to other systemic diseases, especially the correlation to liver disease, in Taiwan.Methods  We identified and retrospectively analyzed clinical criteria‐matched and skin biopsy‐proven patients from 2002 to 2010 at a single medical center. The clinical criteria for diagnosis of TMMA included: (i) crops of telangiectasia superimposed on erythematous macules symmetrically on bilateral upper arms, possibly extending to the forearms, shoulders, V‐shaped area of the anterior chest, back or thighs; (ii) no mucosal or systemic involvement; (iii) not associated with autoimmune diseases, such as lupus erythematosus, dermatomyositis or systemic scleroderma that may induce cutaneous telangiectasia; and (iv) no ataxia or unsteady gait.Results  Twenty‐five patients were enrolled in this study. The male‐to‐female ratio was 19:6. The age of onset was variable, mostly between the third to sixth decades. The V‐shaped area of the anterior chest was commonly involved (68%), in addition to the arms (100%). Viral hepatitis was diagnosed in 56.5% of the patients (13/23); 38.9% (7/18) and 50% (9/18) of the patients had diabetes and hypertension, respectively. In addition, 64.7% of the patients (11/17) had dyslipidemia. The pathological reports of most cases showed only mild perivascular lymphocytic infiltration with or without telangiectasia.Conclusions  TMMA should be assigned to a distinct entity with unique clinical manifestation. It has not been well recognized and mostly misdiagnosed as other diseases with telangiectasia. It is important to evaluate the complete liver function tests when TMMA is suspected.

Reference values of hematology, chemistry, electrolytes, blood gas, coagulation time, and urinalysis in the Chinese rhesus macaques (Macaca mulatta). Xenotransplantation 2012; 19: 244–248.. © 2012 John Wiley & Sons A/S.Abstract: Background:  Due to increasing preclinical study using the rhesus monkeys, the physiological data of these monkeys are very important for the objective evaluation of experimental results. Here, we report the physiological values of the Chinese rhesus monkeys acclimated under a well‐controlled laboratory environment.Methods: Seventy healthy rhesus monkeys of both genders (29 males and 41 females) were used in this study. Available data on hematology, serum biochemistry, electrolytes, blood gas, coagulation time, urinalysis, water consumption, urine volume, and body weight were examined.Results: The lymphocyte values were 1.5–2.5 times higher than the neutrophil values in both genders. In serum biochemistry, there was no significant difference between the two genders. Interestingly, the values of alkaline phosphatase from the monkeys were very high. According to isoenzyme analysis, the percentage of alkaline phosphatase that originated from the bone was 60%, and this value was significantly higher than that from the liver (39%, P = 0.020).Conclusion: Physiological data are very important parameters that can be directly and indirectly related to organ function (e.g. islet, kidney, liver, heart, etc.) in the transplantation model. In this respect, our data constitute valuable references for preclinical study using the Chinese rhesus monkeys.
Investigating the molecular systematic relationships amongst selected Plesionika (Decapoda: Pandalidae) from the Northeast Atlantic and Mediterranean Sea

Published: August 2012

AbstractDespite the high number of species and ecological diversity of pandalid shrimps, there has been no previous attempt to resolve evolutionary relationships of several genera using molecular tools. Although mitochondrial DNA cytochrome oxidase I (COI) is widely used in barcoding studies to delimit species boundaries, additional insights into phylogenetic affinities can be obtained, especially when used in combination with data from additional genes. The knowledge of molecular diversity is essential to understand phylogenetic relationships and will help systematic clarifications. Based on partial fragments of the 16S and COI genes, we have focused specifically on addressing the systematic relationships of the economically and ecologically important shrimp genus Plesionika within a framework of five genera from within the Pandalidae. Our results showed that species within Plesionika are substantially divergent when compared with other genera, exhibiting the highest average nucleotide divergence, with 0.1123 and 0.0846 in COI and 16S genes, respectively. In addition, sequence divergence was found to vary greatly within the genus Plesionika (COI/16S): 0.0247/0.0016 between Plesionika antigai and Plesionika heterocarpus and 0.1616/0.098 between Plesionika heterocarpus and Plesionika edwardsii. We did not find amino acid sequence divergence between P. heterocarpus and P. antigai compared with P. heterocarpus and P. edwardsii (8.10%, K2P distance). Three species of Plesionika (P. antigai, P. heterocarpus and Plesionika scopifera) appear well separated from other Plesionika species in both maximum likelihood and Bayesian analyses. The present study confirms the utility of COI over 16S as a genetic marker to resolve relationships between different species of Plesionika from the Northeast Atlantic and Mediterranean Sea, in addition to species delimitation. The findings highlight the need to further review paraphyly within Plesionika in an attempt to recognize a concordance in the evolutionary history of Plesionika with major ecological and geological events.
Somatic Cell Nuclear Transfer Cloning: Practical Applications and Current Legislation
Authors: Niemann H , Lucas‐Hahn A 
Published: August 2012

ContentsSomatic cloning is emerging as a new biotechnology by which the opportunities arising from the advances in molecular genetics and genome analysis can be implemented in animal breeding. Significant improvements have been made in SCNT protocols in the past years which now allow to embarking on practical applications. The main areas of application of SCNT are: Reproductive cloning, therapeutic cloning and basic research. A great application potential of SCNT based cloning is the production of genetically modified (transgenic) animals. Somatic cell nuclear transfer based transgenic animal production has significant advances over the previously employed microinjection of foreign DNA into pronuclei of zygotes. This cell based transgenesis is compatible with gene targeting and allows both, the addition of a specific gene and the deletion of an endogenous gene. Efficient transgenic animal production provides numerous opportunities for agriculture and biomedicine. Regulatory agencies around the world have agreed that food derived from cloned animals and their offspring is safe and there is no scientific basis for questioning this. Commercial application of somatic cloning within the EU is via the Novel Food regulation EC No. 258/97. Somatic cloning raises novel questions regarding the ethical and moral status of animals and their welfare which has prompted a controversial discussion in Europe which has not yet been resolved.
Severe intergenerational reproductive conflict and the evolution of menopause

Published: August 2012

AbstractHuman menopause is ubiquitous among women and is uninfluenced by modernity. In addition, it remains an evolutionary puzzle: studies have largely failed to account for diminishing selection on reproduction beyond 50 years. Using a 200‐year dataset on pre‐industrial Finns, we show that an important component is between‐generation reproductive conflict among unrelated women. Simultaneous reproduction by successive generations of in‐laws was associated with declines in offspring survivorship of up to 66%. An inclusive fitness model revealed that incorporation of the fitness consequences of simultaneous intergenerational reproduction between in‐laws, with those of grandmothering and risks of dying in childbirth, were sufficient to generate selection against continued reproduction beyond 51 years. Decomposition of model estimates suggested that the former two were most influential in generating selection against continued reproduction. We propose that menopause evolved, in part, because of age‐specific increases in opportunities for intergenerational cooperation and reproductive competition under ecological scarcity.
How to assemble a beneficial microbiome in three easy steps
Authors: Scheuring István , Yu Douglas W. 
Published: August 2012

AbstractThere is great interest in explaining how beneficial microbiomes are assembled. Antibiotic‐producing microbiomes are arguably the most abundant class of beneficial microbiome in nature, having been found on corals, arthropods, molluscs, vertebrates and plant rhizospheres. An exemplar is the attine ants, which cultivate a fungus for food and host a cuticular microbiome that releases antibiotics to defend the fungus from parasites. One explanation posits long‐term vertical transmission of Pseudonocardia bacteria, which (somehow) evolve new compounds in arms‐race fashion against parasites. Alternatively, attines (somehow) selectively recruit multiple, non‐coevolved actinobacterial genera from the soil, enabling a ‘multi‐drug’ strategy against parasites. We reconcile the models by showing that when hosts fuel interference competition by providing abundant resources, the interference competition favours the recruitment of antibiotic‐producing (and ‐resistant) bacteria. This partner‐choice mechanism is more effective when at least one actinobacterial symbiont is vertically transmitted or has a high immigration rate, as in disease‐suppressive soils.
Diversity of plant evolutionary lineages promotes arthropod diversity

Published: August 2012

AbstractLarge‐scale habitat destruction and climate change result in the non‐random loss of evolutionary lineages, reducing the amount of evolutionary history represented in ecological communities. Yet, we have limited understanding of the consequences of evolutionary history on the structure of food webs and the services provided by biological communities. Drawing on 11 years of data from a long‐term plant diversity experiment, we show that evolutionary history of plant communities – measured as phylogenetic diversity – strongly predicts diversity and abundance of herbivorous and predatory arthropods. Effects of plant species richness on arthropods become stronger when phylogenetic diversity is high. Plant phylogenetic diversity explains predator and parasitoid richness as strongly as it does herbivore richness. Our findings indicate that accounting for evolutionary relationships is critical to understanding the severity of species loss for food webs and ecosystems, and for developing conservation and restoration policies.

What's known on the subject? and What does the study add?
Extracorporeal shockwave lithotripsy is effective for the treatment of paediatric renal stones with favourable short‐term safety.
Extracorporeal shockwave lithotripsy for treatment of paediatric renal stones is also safe for the kidney and the child on long‐term follow‐up.
Objective
To evaluate the long‐term effects of extracoporeal shockwave lithotripsy (SWL) for treatment of renal stones in paediatric patients.
Patients and Methods
A database of paediatric patients who underwent SWL monotherapy for treatment of renal stones from September 1990 through to January 2009 was compiled. This study included only patients with follow‐up for more than 2 years. The long‐term effects of SWL were evaluated at the last follow‐up with measurement of patients' arterial blood pressure, estimation of random blood sugar and urine analysis. The results of diastolic blood pressure were plotted against a standardized age reference curve. The treated kidney was examined by ultrasonography for measurement of renal length and detection of stones. The measured renal lengths were plotted against age‐calculated normal renal lengths in healthy individuals.
Results
The study included 70 patients (44 boys (63%) and 26 girls) with mean age at the time of SWL 6.5 ± 3.6 years (range 1–14). The mean follow‐up period was 5.2 ± 3.6 years (range 2.1–17.5). The mean age at last follow‐up was 11.7 ± 5.3 years (range 4.4–27.5). No patients developed hypertension or diabetes. Only one treated kidney was smaller than one standard deviation of the calculated length. The cause of this was obstruction by a stone in the pelvic ureter 3 years after SWL.
Conclusion
The long‐term follow‐up after SWL for treatment of renal stones in paediatric patients showed no effect on renal growth and no development of hypertension or diabetes.
International Productivity Differences, Trade and the Distributions of Factor Endowments
Authors: Sly Nicholas 
Published: August 2012

AbstractThis paper presents a model of task assignment and worker matching to explore how the distributions of labor endowments within countries influence aggregate productivity and international trade patterns. Higher moments of the skill distribution have complex relationships with the organization of the labor force. First, labor endowments skewed toward high abilities exhibit positive assortment of workers across tasks, while countries with distributions of ability skewed towards low abilities exhibit underemployment. Second, greater dispersion improves aggregate productivity in countries that experience underemployment, but worsens productivity where there is assortative assignment. Furthermore, the shape and size of factor endowments are shown to jointly determine a global pattern of comparative advantage. Countries are more likely to export their abundant factors when labor markets organize heterogenous workers effectively. These predictions receive empirical support from Organization for Economic Co‐operation and Development (OECD) countries using measures of diversity constructed from educational attainment.
Import Variety and Welfare Gain in China
Authors: Chen Bo , Ma Hong 
Published: August 2012

AbstractThis paper provides the first comprehensive measure of how much China has gained from import variety from 1997 to 2008, by adopting a simplified trade restrictiveness index. Utilizing the most disaggregated product‐level import data available for China, the paper finds that the welfare gain as a result of new import variety amounts to 4.9% of gross domestic product (GDP), or 0.4% annually, after controlling for the prevalent imported intermediate inputs for processing. Furthermore, the empirical strategy is extended to investigate specific contributions of different countries, and finds that China gains the most from Japan, followed by Canada and Germany. Countries with abundant natural resources, such as Indonesia, Russia, Iran, and Australia, also contribute significantly to China's welfare.

Scandinavian Journal of Psychology 53, 512–522.This study investigates the associations of longitudinal Big Five personality profiles with long‐term health in 304 adults (53% males). Personality traits (Neuroticism, Extraversion, Openness, Conscientiousness, Agreeableness) were assessed at ages 33, 42, and 50. Subjective (self‐rated health, symptoms, psychological distress) and objective (body mass index, waist‐to‐hip ratio, blood pressure, cholesterol, triglycerides) indicators of health were measured at ages 42 and 50. Five longitudinally stable personality profiles were extracted over 17 years by latent profile analysis. The levels of traits were the same in each profile at each age. Resilient individuals (N = 65; Neuroticism low, other traits high) had the best subjective health and Overcontrolled individuals (N = 40; Neuroticism high, other traits low) the poorest health over eight years. Reserved individuals (N = 25; high Conscientiousness, other traits low), Undercontrolled (N = 41; high Openness and Extraversion, low Conscientiousness), and Ordinary (N = 133; all traits scored medium) individuals were in the middle of these extremes in subjective health. No differences between the profiles were found in the objective indicators of health. Thus, overcontrol and resilience were most discriminative in terms of good health. Moreover, personality profiles revealed associations with health to be more nuanced than simply being composed of single traits. High Extraversion needed to be combined with high Conscientiousness (Resilients) in order to be associated with the best health; high Extraversion with low Conscientiousness (Undercontrolled) was associated with average health; and low Extraversion with high Neuroticism (Overcontrolled) was associated with the poorest health.
A Limited Repertoire of Emotion Regulation Strategies is Associated with Internalizing Problems in Adolescence
Authors: Lougheed Jessica P. , Hollenstein Tom 
Published: August 2012

AbstractThe present study was designed to test whether the beneficial effects of emotion regulation (ER) have less to do with the use of singular, ‘adaptive’ strategies and more to do with using a range of strategies. Using a community sample of adolescents (N = 177, M = 13.6 years), groups based on five measures of ER (reappraisal, suppression, concealing, emotional engagement, and adjusting) were created through latent profile analysis. A six‐group model was the best fit. As hypothesized, ER profiles with high scores on one or two indicators were associated with higher levels of internalizing problems, whereas profiles with average to high scores on several indicators and high scores on adjusting were associated with lower levels of internalizing problems (depression, general anxiety, and social anxiety). Results highlight the importance of having different ER strategies to use and that a limited ER repertoire in adolescence may be associated with internalizing problems.
A Conceptual Regulatory Framework for the Design and Evaluation of Complex, Participative Cultural Planning Strategies
Authors: Sacco Pier Luigi , Crociata Alessandro 
Published: August 2012

AbstractThe current hype about culture‐led local development models is causing an increasing interest in cultural policies in the broader context of urban policy. This is not necessarily a transitory situation bound to fade once the hype is over. Under certain conditions, there is room to believe that culture may indeed become a main development driver of urban systems. For this to happen, however, it is necessary to abandon simple mono‐causal developmental schemes (such as the ‘creative class’ model) and look for more articulated approaches. This calls in turn for a complex systems‐based conceptual framework that is at the same time rich enough to capture the complexity of the interdependences among policy and state variables, and manageable enough to be of practical use, not only for policy design professionals but also for local stakeholders who want to take part in collective decision‐making processes. Inclusiveness and collective decision making are almost unavoidable in the case of cultural planning strategies, as the social sustainability of culture‐based value creation processes crucially depends on boosting the level of access to cultural opportunities by local residents. In this article we present an approach that may be a tentative first step in this direction.
Contesting Sustainability: ‘SMARTGrowth’ and the Redevelopment ofAustin'sEastside
Authors: Tretter Eliot M. 
Published: August 2012

AbstractThe compatibility between an agenda for sustainable urban development and the neoliberal economic restructuring of urban space has been observed within cities in developed countries across the globe. From providing economic support to local ‘green’ industries to creating bike lanes, municipalities develop sustainability strategies that are designed to boost their competitive advantage. Moreover, municipalities are responding to demands from popular social movements and national governments that seek to reconfigure societal relationships with the natural environment in cities. Cities are increasingly understood not as part of the ecological crisis but as part of the solution, or as places where alternative patterns of sustainable consumption and new socially and ecologically responsible industries can be developed. Over the last decade in Austin, environmental sustainability has become an uncontested paradigm that has progressively shaped the city's urban space and policy. Two competing conceptualizations of the environment, so‐called ‘environmental’ and ‘just’ sustainability groups, are explored in this article. I demonstrate how the notion of environmental sustainability has been selectively incorporated into the hegemonic vision of Austin's strategic growth plan. I argue that the dominance of this conceptualization is best understood by asking what counts as the ‘environment’ for environmentalists, and understanding the unstated assumptions about the environment shared by the business community and environmentalists.
