First Report of Bacterial Canker of Kiwifruit Caused by Pseudomonas syringae pv. actinidiae in Turkey
Authors: Bastas K. K. , Karakaya A. 
Published: December 2011

A new disease was observed during the spring and autumn of 2009 and 2010 on kiwifruit plants (Actinidia deliciosa cv. Hayward) in Rize Province of Turkey. Disease incidence was estimated as 3% in approximately 10 ha. Symptoms were characterized by dark brown spots surrounded by yellow halos on leaves and cankers with reddish exudate production on twigs and stems. Eight representative bacterial strains were isolated from leaf spots and tissues under the bark on King's B medium (KB) and identified as Pseudomonas syringae pv. actinidiae on the basis of biochemical, physiological (1,2), and PCR tests (3). Bacteria were gram negative, rod shaped, and nonfluorescent on KB; positive for levan production, sucrose and inositol utilization, and tobacco (Nicotiana tabacum cv. White Burley) hypersensitivity; and negative for growth at 37°C, oxidase, potato soft rot, arginine dihydrolase, urease, arbutin, erythritol, lactic acid, aesculin hydrolysis, gelatin liquefaction, and syringomycin production. Identity of the eight isolates was confirmed by PCR using P. syringae pv. actinidiae-specific primers PsaF1/R3 to generate a 280-bp DNA fragment (3). P. syringae pv. actinidiae reference strain NCPPB 3739, and CJW7 from Jae Sung Jung, Department of Biology, Sunchon National University, Korea, were employed in all biochemical, physiological, and molecular tests as positive controls. Pathogenicity was confirmed by artificial inoculation of 2-year-old A. deliciosa cv. Hayward. A bacterial suspension (108 CFU ml–1) was injected into kiwifruit twig tips, stems, and leaves with a hypodermic syringe, and the inoculated plants were placed at 25 to 28°C and 80% relative humidity growth chamber for 3 weeks. First symptoms were observed on leaves within 5 days after inoculation and on twigs after 20 days. No symptoms were observed on control plants that were inoculated with sterile water. Reisolation was made from dark brown lesions surrounded by yellow halos on leaves and cankers on twigs and stem and their identities were confirmed using the techniques previously described. All tests were performed three times and pathogenicity tests employed three plants for each strain. To our knowledge, this is the first report of P. syringae pv. actinidiae causing disease on kiwifruit in Turkey. Kiwifruit production in Turkey has expanded rapidly during the last 10 years ( http://www.tuik.gov.tr ) and phytosanitary measures are needed to prevent further spread of the bacterium to other kiwifruit orchards.

AbstractObjectives:  Here we present a model aiming to provide an estimate of time from tumour genesis, for grade II gliomas. The model is based on a differential equation describing the diffusion–proliferation process. We have applied our model to situations where tumour diameter was shown to increase linearly with time, with characteristic diametric velocity.Materials and methods:  We have performed numerical simulations to analyse data, on patients with grade II gliomas and to extract information concerning time of tumour biological onset, as well as radiology and distribution of model parameters.Results and conclusions:  We show that the estimate of tumour onset obtained from extrapolation using a constant velocity assumption, always underestimates biological tumour age, and that the correction one should add to this estimate is given roughly by 20/v (year), where v is the diametric velocity of expansion of the tumour (expressed in mm/year). Within the assumptions of the model, we have identified two types of tumour: the first corresponds to very slowly growing tumours that appear during adolescence, and the second type corresponds to slowly growing tumours that appear later, during early adulthood. That all these tumours become detectable around a mean patient age of 30 years could be interesting for formulation of strategies for early detection of tumours.

AbstractObjective  We wished to ascertain if there is an association between symptoms of attention‐deficit/hyperactivity disorder (ADHD) and home environment in children with ADHD and non‐ADHD siblings, controlling for other environmental measures.Methods  96 children with ADHD combined type (ADHD‐CT) and their siblings participated in the study. Parent and teacher Conners' rating scales were completed and home environment was assessed using the middle childhood and early adolescent Home Observation for Measurement of the Environment (HOME). ADHD symptoms were assessed for correlation with HOME in children with ADHD‐CT and non‐ADHD siblings and multiple regression analysis was used to control for gender, socio‐economic status, exposure to nicotine, exposure to alcohol in utero, birth weight, gestational age, pregnancy and perinatal risk factors. The presence of oppositional disorders was assessed for association with HOME score in those with ADHD‐CT. The multiple regression analysis was repeated controlling for environmental factors and for oppositional disorders in those with ADHD‐CT. Oppositional symptoms were assessed for correlation with HOME score in non‐ADHD siblings.Results  Teacher‐rated hyperactive/impulsive scores correlated with HOME (r=−0.27, P < 0.01) in children with ADHD‐CT. This association remained significant when other environmental factors and oppositional disorders were controlled for. Environmental factors and gender contributed to 30% of the variance of ADHD symptoms in ADHD‐CT. Parent‐rated hyperactive/impulsive scores also correlated with HOME (r=−0.28, P < 0.05) for non‐ADHD siblings. An association between HOME and diagnosis of oppositional defiant disorder or conduct disorder was found for children with ADHD‐CT and between HOME and oppositional symptoms in non‐ADHD siblings.Conclusions  The home environment has a small but significant association with hyperactive/impulsive symptoms in children with ADHD‐CT and non‐ADHD siblings. This association remained when other environmental factors were taken into account. Oppositional symptoms are associated with home environment in ADHD‐CT and in non‐ADHD siblings.
Human‐knowledge resources and interorganisational systems
Authors: Ibrahim Mohammed , Ribbers Pieter M. , Bettonvil Bert 
Published: December 2011

AbstractThis paper analyses how human‐knowledge resources affect interorganisational systems (IOS) capabilities and subsequently attainment of operational and strategic benefits. A conceptual model is constructed combining the transaction cost economics (TCE) view, resource‐based view (RBV) and insights from IOS literature. The model is tested through a triangulation approach combining two qualitative case studies and a quantitative field study within the logistics sector. This sector is chosen due to its need for high reliance on information technology. The findings indicate that human knowledge positively influences IOS capabilities related to cross‐organisational business processes and transfer of knowledge. Findings also show that strategic benefits are the consequence of knowledge transfer, when the transfer supports business processes resulting in operational benefits. The main theoretical contribution of this paper is that it combines a TCE view and RBV to analyse the effect of relationship‐specificity of human‐based knowledge resources in IOS.

Authors: Hong Hui , Luo Yongkang , Zhu Sichao , Shen Huixing 
Published: December 2011

SummaryQuality predictive models were developed to predict the freshness of bighead carp (Aristichthys nobilis) fillets during storage at different temperatures. Quality indices [sensory score, total volatile base nitrogen (TVB‐N), total aerobic counts (TAC) and K value] at −3, 0, 3, 9 and 15 °C were estimated and kinetically modelled by the Arrhenius equation. The activation energy (EA) of sensory score, TVB‐N, TAC and K value was 78.17, 75.93, 106.53 and 76.21 kJ mol−1, and the corresponding rate constants (k0) were 1.16 × 1015, 2.60 × 1014, 4.05 × 1019 and 1.36 × 1015. The high regression coefficients (R2 > 0.87) indicated the acceptability of the zero‐order reaction for sensory score, TVB‐N, TAC and K value. Relative errors between predicted and observed freshness indicators values of sensory score, TVB‐N, TAC and K value were all below 10% except the values at 6th day of K value, 3rd day and 9th day of TVB‐N. These results indicated that the models based on sensory score, TVB‐N, TAC and K value could effectively predict the freshness indicators of bighead carp fillets at the range of −3 to 15 °C.

SummaryBecause of secreting large amounts of enzymes, Aspergillus oryzae was widely used in the fermentation of soy sauce in many Asian countries. Here, N+ ion implantation mutagenesis was applied to improve the ability of A. oryzae to secrete acid protease. Several mutants were screened using three kinds of plates (Casein medium, Czapek’s medium and carboxymethyl cellulose medium agar plates). Compared with the other mutants, the mutant A100‐8 could secrete the most protease. Acid protease activity of A100‐8 was enhanced about 44.1% at 36 h by koji fermentation test. In addition, A100‐8 was stable by periodically subculturing and maintaining on the agar slant. The mRNA expression levels of two kinds of acid protease (serine carboxypeptidase and aspartyl protease) were measured by RT‐PCR at different periods. Serine carboxypeptidase and some kinds of aspartyl protease of A100‐8 were significantly (P < 0.01) expressed higher than the control at all times.

Published: December 2011

SummaryThe objective of this work was to study the effects of the combination of glucose oxidase (Gox), α‐amylase (AM) and xylanase (Xyl) on dough properties and bread quality, applying response surface analysis. Gox improved dough stickiness and bread crumb uniformity, but had a negative effect on specific volume. A positive synergist effect was observed combining Xyl and AM on specific volume and crumb firmness but this synergist effect was negative on crumb uniformity. Using the ‘desirability function’, two optimal formulations for the baking process were obtained. In the first optimisation, the combination of Gox 0.0026, Xyl 0.016 and AM 0.01 g per 100 g of flour will allow to obtain breads with high specific volume and low firmness. Second optimisation (Gox 0.0037, Xyl 0.0089 and AM 0.0105 g per 100 g of flour) will allow to obtain breads with 37% higher specific volume than control and, additionally, with low dough stickiness.
Bridging evidence and consensus methodology for inherited metabolic disorders: creating nutrition guidelines
Authors: Singh Rani H. , Rohr Fran , Splett Patricia L. 
Published: December 2011

AbstractRationale, aims and objectives  The management of many inherited metabolic disorders (IMDs) is dependent on nutrition intervention, but few clinical management guidelines for these uncommon disorders exist. Clinicians are forced to make nutrition treatment decisions using limited data. This results in clinical variations in both service and cost. We describe a method for establishing management guidelines to help clinicians treat patients with IMDs.Methods  The Southeast Newborn Screening and Genetics Collaborative (Region 3) convened a group of nine national experts in metabolic nutrition to determine the pertinent issues in the development of nutrition management guidelines for IMDs. These experts were trained in evidence analysis and examined established consensus techniques for guideline development.Results  The workgroup developed a multi‐step process for guideline development known as the Delphi‐Nominal Group‐Delphi‐Field Testing methodology, which includes a review of scientific and grey (unpublished) literature, a Delphi survey of practice, a nominal group meeting to clarify discrepancies, a formulation of recommendations and a second Delphi round to assess the degree of consensus with the proposed recommendations. External review and field testing are also built into the process.Conclusion  The evidence‐ and consensus‐based method suggested for the development of nutrition management guidelines for IMDs will result in the production of consistent and accessible guidelines that can be created in a timely and cost‐effective manner and offer a validated methodology to develop management guidelines for this field to optimize outcomes.

AbstractThe impact of ecology and social organization on genetic structure at landscape spatial scales, where gene dynamics shape evolution as well as determine susceptibility to habitat fragmentation, is poorly understood. Attempts to assess these effects must take into account the potentially confounding effects of history. We used microsatellites to compare genetic structure in seven bat species with contrasting patterns of roosting ecology and social organization, all of which are codistributed in an ancient forest habitat that has been exceptionally buffered from radical habitat shifts. Over one thousand individuals were captured at foraging sites and genotyped at polymorphic microsatellite loci. Analyses of spatially explicit genotype data revealed interspecies differences in the extent of movement and gene flow and genetic structure across continuous intact forest. Highest positive genetic structure was observed in tree‐roosting taxa that roost either alone or in small groups. By comparison, a complete absence of genetic autocorrelation was noted in the cave‐roosting colonial species across the study area. Our results thus reveal measurable interspecies differences in the natural limits of gene flow in an unmodified habitat, which we attribute to contrasting roosting ecology and social organization. The consequences of ecology and behaviour for gene flow have important implications for conservation. In particular, tree‐roosting species characterized by lower vagility and thus gene flow will be disproportionally impacted by landscape‐scale forest clearance and habitat fragmentation, which are prevalent in the study region. Our method also highlights the usefulness of rapid sampling of foraging bats for assaying genetic structure, particularly where roosting sites are not always known.

Kim IK, Tan JC, Lapasia J, Elihu A, Busque S, Melcher ML. Incidental kidney stones: a single center experience with kidney donor selection.Abstract:  The presence of kidney stones has been a relative contraindication for living donation. With the widespread use of more sensitive imaging techniques as part of the routine living donor workup, kidney stones are more frequently detected, and their clinical significance in this setting is largely unknown. Records from 325 potential kidney donors who underwent MRA or CT‐angiography were reviewed; 294 proceeded to donation. The prevalence of kidney stones found incidentally during donor evaluation was 7.4% (24 of 325). Sixteen donors with stones proceeded with kidney donation. All incidental calculi were nonobstructing and small (median 2 mm; range 1–9 mm). Eleven recipients were transplanted with allografts containing stones. One recipient developed symptomatic nephrolithasis after transplantation. This recipient was found to have newly formed stones secondary to hyperoxaluria, suggesting a recipient‐driven propensity for stone formation. The remaining ten recipients have stable graft function, postoperative ultrasound negative for nephrolithiasis, and no sequelae from stones. No donor developed symptomatic nephrolithiasis following donation. Judicious use of allografts with small stones in donors with normal metabolic studies may be acceptable, and careful follow‐up in recipients of such allografts is warranted.

With 3 figures and 5 tablesAbstractTo identify quantitative trait loci (QTL) controlling heat tolerance in rice, the progeny of BC1F1 and F2 populations derived from an IR64 × N22 cross were exposed to 38/24°C for 14 days at the flowering stage, and spikelet fertility was assessed. A custom 384‐plex Illumina GoldenGate genotyping assay was used to genotype the F2 and selected BC1F1 plants. Four single nucleotide polymorphisms were associated with heat tolerance in the BC1F1 population using selective genotyping and single marker analysis, and four putative QTL were found to be associated with heat tolerance in the F2 population. Two major QTL were located on chromosome 1 (qHTSF1.1) and chromosome 4 (qHTSF4.1). These two major QTL could explain 12.6% (qHTSF1.1) and 17.6% (qHTSF4.1) of the variation in spikelet fertility under high temperature. Tolerant allele of qHTSF1.1 was from the susceptible parent IR64, and that of qHTSF4.1 was from tolerant parent N22. The effect of qHTSF4.1 on chromosome 4 was confirmed in selected BC2F2 progeny from the same IR64 × N22 cross, and the plants with qHTSF4.1 showed significantly higher spikelet fertility than other genotypes.
Emotional intelligence: A promise unfulfilled?
Authors: MATTHEWS GERALD , ZEIDNER MOSHE , ROBERTS RICHARD D. 
Published: December 2011

AbstractEmotional intelligence (EI) is a relatively new construct in differential psychology. Proponents of EI have made strong claims for its importance in basic and applied psychology. This article considers whether the promise of EI has been fulfilled. We examine various fundamental challenges to establishing EI as a major individual differences factor, including cross‐cultural issues. We then examine strategies for assessing EI as a personal quality distinct from general intelligence and personality, and evaluate leading tests and scales for EI. Various sources of validity evidence demonstrate the value of research on EI, but we also identify various weaknesses of existing instruments. It appears that there is no strong, over‐arching general factor of EI that shapes human emotional functioning across a range of diverse contexts. Instead, we advocate a “multipolar” conception of EI that discriminates temperament, information‐processing, emotion‐regulation and acquired skills. Focusing research on more narrowly defined but conceptually coherent research domains may be a more productive strategy than seeking to define an all‐embracing general EI.
‘Get alongside us’, women's experiences of being overweight and pregnant in Sydney, Australia

AbstractStudies of women's experiences of being overweight and pregnant are limited in the literature. Given the increasing rates of obesity in pregnant women, and the impact of being overweight on the health of the mother and the child, this qualitative descriptive study aimed to explore the perceptions and experiences of overweight pregnant women attending two maternity units in Sydney, Australia. Fourteen women aged between 25 and 42 years with a body mass index greater than 30 kg/m2 participated in a face‐to‐face interview in their third trimester of pregnancy or in the early post‐natal period. All interviews were recorded and transcribed. Field notes were also recorded following each interview. Data were analysed using thematic analysis. Four themes were identified in the data: ‘being overweight and pregnant’, ‘being on a continuum of change’, ‘get alongside us’ and finally ‘wanting the same treatment as everyone else’. Most women recognised their weight as an issue both for their own health and well‐being and for its impact on the baby. Women believed health professionals should address the issue of obesity with them but do so in a supportive and positive way that recognised their individual needs and expectations. Health professionals need to consider new approaches or models of care for overweight women that give them support and enable individual needs and expectations to be met. Culturally specific programs may also need to be developed.
Association between the Interleukin 10−1082G>A polymorphism and coronary heart disease risk in a Caucasian population: a meta‐analysis

SummaryInterleukin‐10 (IL‐10) is a cytokine with anti‐inflammatory and B‐cell‐stimulating activity. IL‐10 is expressed in human atherosclerotic plaques and studies have shown the involvement of IL‐10 in the atherosclerotic process. The IL‐10−1082G/A polymorphism is one of the most commonly studied polymorphisms in this gene because of its association with coronary heart disease (CHD) risks, but previous results have been conflicting. We performed a meta‐analysis using six eligible case–control studies (including 14 data sets) with a total of 5006 patients and 3968 controls to summarize the existing data on the association between the IL‐10−1082G/A polymorphism and CHD risk. Compared with the common IL‐10−1082G/A GG genotype, the carriers of variant genotypes (IL‐10−1082GA/AA) had a 1.12‐fold elevated risk of CHD (95% CI = 1.01–1.23, P = 0.03) under the dominant genetic model, as estimated using a random effect model. The effect of the IL‐10−1082G/A polymorphism was further evaluated using stratification analysis. In the three disease of artery studies, with the variant genotypes had a not obvious increased risk of disease of artery (OR = 1.19, 95% CI = 0.98–1.44, P = 0.08) as estimated using a fixed effect model. Similar results were found in the nine myocardial infarction studies (OR = 1.13, 95% CI = 1.00–1.27, P = 0.05). It was also demonstrated that the increased risk of CHD associated with IL‐10−1082G/A variant genotypes was more pronounced in Caucasians (OR = 1.12, 95% CI = 1.01–1.23, P = 0.03). Our meta‐analysis suggests that the IL‐10−1082G/A polymorphism genotypes (GA+AA) might be associated with an increased risk of CHD, especially in Caucasians.
