Abela‐Hofbauerová I, Münzbergová Z & Skuhrovec J (2011). The effect of different natural enemies on the performance of Cirsium arvense in its native range. Weed Research51, 394–403.SummaryUnderstanding the effects of herbivores on weedy plant performance under different habitat conditions may provide useful information for limiting the spread of these plant species in their native and invaded ranges. A critical drawback to using herbivores to limit the spread of weedy plant species is the limited knowledge regarding the effects of different natural enemies on plant performance under natural conditions and in different habitat types. The aim of this study was to collect information on the degree and types of damage caused by natural enemies and their effects on the performance of the weed species Cirsium arvense, under different abiotic conditions in its native range in the Czech Republic. Damage induced by different natural enemies of C. arvense in four different populations in wet and dry sites was studied. The most common types of damage found in C. arvense were folivory (eaten foliage), external stem damage and leaf necrosis, and their occurrence varied strongly in space and time. Different plant damage types tended to be significantly associated with each other. It was therefore difficult to separate the effects of individual damage types and to study their interactions. Overall, the results indicate that in its native range, C. arvense experiences high levels of herbivory, with stem damage, flower herbivory and folivory having the strongest effects on plant performance. Experimental studies that would separate the effect of single herbivores are, however, needed to confirm this.

Délye C, Pernin F & Michel S (2011). ‘Universal’ PCR assays detecting mutations in acetyl‐coenzyme A carboxylase or acetolactate synthase that endow herbicide resistance in grass weeds. Weed Research51, 353–362.SummaryHerbicides inhibiting acetyl‐coenzyme A carboxylase (ACCase) or acetolactate synthase (ALS) are key for grass weed control. Yet, numerous cases of resistance have evolved. Using the derived cleaved amplified polymorphic sequence method, we developed molecular assays to detect amino acid replacements at the seven ACCase codons (1781, 1999, 2027, 2041, 2078, 2088 and 2096) and at two ALS codons (197 and 574) known to play a role in herbicide resistance in grass weeds. For each codon, one assay detecting all known amino acid replacements endowing herbicide resistance was developed. The nine assays were successfully used to genotype ACCase and ALS in 39 grass species. Their flexible design enables easy detection of new mutations at the targeted codons. Because they can be implemented with basic molecular biology facilities and no previous knowledge of the ACCase or ALS sequence of the grass weed of interest, these assays are tools of choice to easily detect resistance caused by alteration(s) of ACCase or ALS in such species.

Stress and coping in caregivers of patients awaiting solid organ transplantation.  Clin Transplant 2012: 26: 97–104.  © 2011 John Wiley & Sons A/S.Abstract:  Caregivers for patients undergoing solid organ transplantation play an essential role in the process of transplantation. However, little is known about stress and coping among these caregivers. Six hundred and twenty‐one primary caregivers of potential candidates for lung (n = 317), liver (n = 147), heart (n = 115), and/or kidney (n = 42) transplantation completed a psychometric test battery at the time of the candidate’s initial pre‐transplant psychosocial evaluation. Caregivers were generally well adjusted, with only 17% exhibiting clinical symptoms of depression (Beck Depression Inventory‐II score >13) and 13% reporting clinical levels of anxiety (State Trait Anxiety Inventory score >48). Greater caregiver burden and negative coping styles were associated with higher levels of depression. Greater objective burden and avoidant coping were associated with higher levels of anxiety. Caregivers evidenced a high degree of socially desirable (i.e., defensive) responding, which may reflect a deliberate effort to minimize fears or worries so as to not jeopardize patients’ listing status.

Ansari M, Rougemont A‐L, Le Deist F, Ozsahin H, Duval M, Champagne MA, Fournet J‐C. Secondary pulmonary alveolar proteinosis after unrelated cord blood hematopoietic cell transplantation.Abstract:  PAP is a rare alveolointerstitial lung disorder characterized histologically by the intra‐alveolar accumulation of eosinophilic and PAS‐positive material. We observed two cases of PAP after unrelated CB hematopoietic progenitor cell transplantation in children with ALL. No antagonist activity toward GM‐CSF was identified in the patient tested. The putative multifactorial PAP etiology is discussed. This potentially curable condition should be considered in a CB allograft recipient with alveolointerstial lung disorder.

Tuberculous hepatic abscess appearing after liver transplantation in a patient with human immunodeficiency virus and hepatitis B and C virus co‐infection. Transpl Infect Dis 2011: 13: 515–519. All rights reservedAbstract: Tuberculosis infection occurs relatively frequently in solid organ transplant recipients, although the occurrence of tuberculous hepatic abscesses is uncommon. Anti‐tuberculous therapy has several concerns in transplant recipients, including an increased risk of cellular rejection and potential hepatotoxicity. We present the case of a human immunodeficiency virus‐infected liver transplant patient who developed multiple tuberculous liver abscesses. Treatment with isoniazid, ethambutol, pyrazinamide, and moxifloxacin was efficacious, well tolerated, and safe.

Published: March 2011

AbstractAlthough tropical environments are often considered biodiversity hotspots, it is precisely in such environments where least is known about the factors that drive species richness. Here, we use phylogenetic comparative analyses to study correlates of species richness for the largest Neotropical amphibian radiation: New World direct‐developing frogs. Clade‐age and species richness were nonsignficantly, negatively correlated, suggesting that clade age alone does not explain among‐clade variation in species richness. A combination of ecological and morphological traits explained 65% of the variance in species richness. A more vascularized ventral skin, the ability to colonize high‐altitude ranges, encompassing a large variety of vegetation types, correlated significantly with species richness, whereas larger body size was marginally correlated with species richness. Hence, whereas high‐altitude ranges play a role in shaping clade diversity in the Neotropics, intrinsic factors, such as skin structures and possibly body size, might ultimately determine which clades are more speciose than others.
Genetic differences among populations in sexual dimorphism: evidence for selection on males in a dioecious plant

Published: March 2011

AbstractGenetic variation among populations in the degree of sexual dimorphism may be a consequence of selection on one or both sexes. We analysed genetic parameters from crosses involving three populations of the dioecious plant Silene latifolia, which exhibits sexual dimorphism in flower size, to determine whether population differentiation was a result of selection on one or both sexes. We took the novel approach of comparing the ratio of population differentiation of a quantitative trait (QST) to that of neutral genetic markers (FST) for males vs. females. We attributed 72.6% of calyx width variation in males to differences among populations vs. only 6.9% in females. The QST/FST ratio was 4.2 for males vs. 0.4 for females, suggesting that selection on males is responsible for differentiation among populations in calyx width and its degree of sexual dimorphism. This selection may be indirect via genetic correlations with other morphological and physiological traits.
Response of Trifolium repens to UV‐B radiation: morphological links to plant productivity and water availability

Published: March 2011

AbstractThis study used nine populations of Trifolium repens L. (white clover) to investigate possible relationships between plant morphological attributes and responses to ultraviolet‐B (UV‐B) radiation. Plants were exposed to 0 or 13.3 kJ·m−2·day−1 UV‐B for 12 weeks. Drought was applied in parallel to these treatments during the last 4 weeks of the experiment to test whether limited moisture availability would alter morphological UV‐B responses. UV‐B affected plant morphology under well‐watered conditions, reducing leaf size by 15%, leaf number by 5% and stolon elongation by 19%. The number of leaf primordia in the apical bud was decreased by 4% under UV‐B, and by 12% under drought. In drought‐exposed plants, leaf size was reduced by 50%, leaf number by 30% and stolon elongation by 60%. In addition, drought reduced specific leaf area (SLA) by 33% and increased leaf percentage dry mass (PDM) by 40%. UV‐B‐induced reduction in plant biomass in the T. repens populations was associated with higher plant productivity and this was further linked to larger leaf size as well as to lower PDM. In conclusion, the findings suggest that morphological attributes conferring fast potential growth under productive conditions carry a cost in the form of lower biomass accumulation under UV‐B.
Resistance of ‘Roxana’ to powdery mildew and its presence in some European spring barley cultivars
Authors: Dreiseitl Antonín 
Published: March 2011

With 3 tables AbstractIn the last two decades, powdery mildew resistance has been investigated in a large number of barleys grown in the Czech Republic. Apart from those with the Mlo resistance, 29 spring barley cultivars were as fully resistant. In this study, tests on 22 of these cultivars are presented. Forty reference isolates of Blumeria graminis f. sp. hordei, including five isolates collected in 2008, were used. Two of the latter were virulent on 18 cultivars including ‘Havanna’, ‘Marnie’ and ‘Roxana’. ‘Roxana’ derived its resistance from wild barley accession 1B–86B, and was the first cultivar registered with this resistance. It is recommended that this resistance be designated Ro. According to their pedigrees, the resistances of ‘Andrey’ and ‘Lilly’ were also derived from ‘Marnie’. It is likely that the resistance of IN 0614 and NORD 06/1108 is Mlo. Thus, among the 29 cultivars, there are only two resistances, and only Mlo remains fully resistant.

Published: March 2011

With 2 figuresAbstractDevelopment of PCR‐based markers for single‐nucleotide polymorphism (SNP) detection is prerequisite for various genetic analyses. The use of restriction enzymes (REs) following PCR amplification is a common and relatively low cost method for SNP detection. Simple and cost‐effective methodologies for SNP marker development that would enhance the use of SNP‐based technologies are desirable. As an alternative analytical method for selection of REs for recognition of SNP motifs for marker development that does not require computer‐based selection of REs is herein described. Given that only 12 REs are required for the detection of any SNP motif, the method described in this study is relatively inexpensive and technically simple.

Published: March 2011

AbstractBackground and Aim: Inflammatory bowel disease (IBD) is a multi‐factorial disease with an unknown etiology characterized by oxidative stress, leukocyte infiltration and a rise in inflammatory cytokines. This study was conducted to investigate lithium in 2,4,6‐trinitrobenzene sulfonic acid (TNBS)‐induced chronic model of experimental IBD, and the contribution of potassium channels as a possible underlying mechanism.Methods: Experimental IBD was induced in rats by a single colonic administration of 10 mg of TNBS. Lithium, Glibenclamide (a potassium channel blocker), Lithium + Glibenclamide, Cromakalim or Lithium + Glibenclamide + Cromakalim were given twice daily for 7 successive days. At the end of the experiment, macroscopic and histopathologic scores, colonic malondialdehyde (MDA), tumor necrosis factor‐α (TNF‐α) level, and myeloperoxidase (MPO) activity as well as plasma lithium level were assessed.Results: Both macroscopic and histological features of colonic injury were markedly ameliorated by lithium. Likewise, the elevated amounts of MPO and MDA were diminished as well as those of TNF‐α (P < 0.05). Glibenclamide reversed the effect of lithium on these markers, Addition of cromakalim abrogated the effects mediated by glibenclamide and markedly decreased MPO activity, MDA level and TNF‐α content (P < 0.0.05). Macroscopic and microscopic scores and biochemical markers were significantly decreased in Cromakalim‐treated animals. No significant difference was observed between TNBS and Glibenclamide groups.Conclusion: Lithium exerts prominent anti‐inflammatory effects on TNBS‐induced colitis in rats. Potassium channels contribute to these beneficial properties.
Pleural controversy: Aetiology of pneumothorax
Authors: HAYNES DEMONDES , BAUMANN MICHAEL H. 
Published: March 2011

ABSTRACTPneumothoraces are classified as spontaneous, traumatic and iatrogenic. Spontaneous pneumothoraces that occur without recognized lung disease are termed primary spontaneous pneumothoraces (PSP), whereas those that occur due to an underlying lung disease are termed secondary spontaneous pneumothoraces. The aetiology of secondary, traumatic or iatrogenic pneumothoraces is not usually debated. However, the aetiology of PSP is potentially controversial and often debated. Therefore, PSP is the focus of this article. There are several purported causes, which include blebs, bullae, emphysema‐like changes (ELC) and pleural porosity. The controversy is valid because of the importance of recurrence prevention. This article reviews the current available evidence for the causes of PSP. The causes of PSP are likely a combination ELC, pleural porosity and other potential factors.
Comparison of cardiorespiratory fitness and body mass index between rural and urban youth: Findings from the East of England Healthy Hearts Study
Authors: Sandercock Gavin R.H. , Ogunleye Ayodele , Voss Christine 
Published: March 2011

AbstractBackground:  The aim of the present study was to determine if there were differences in cardiorespiratory fitness (CRF) and body mass index (BMI) in rural versus urban youth.Methods:  We measured BMI in 6628 10.0–15.9‐year‐olds and classified them as normal weight, overweight or obese. CRF was assessed with a 20‐m shuttle‐run test and subjects were classified as unfit, fit or highly fit. Rural or urban dwelling was calculated from postcodes.Results:  There were no differences in frequency of BMI categories or CRF between rural and urban children (<13 years) or adolescents (>13 years). Rural adolescents were less likely to be fit (OR = 0.80; 95%CI 0.67–0.96) or highly fit (OR = 0.69; 95%CI 0.55–0.86) independent of their age, sex, race or level of deprivation.Conclusions:  Whilst there were no differences evident in children <13 years, rural adolescents were significantly less likely to meet criterion‐based cut‐off points for CRF. Research to elucidate why such differences exist is warranted.

Published: March 2011

AbstractBackground:  Microvascular changes have been associated with the metabolic syndrome.Methods:  We included 869 participants aged ≥40 years from the High‐risk for Diabetes Changfeng Study, who had gradable fundus photographs. On digital photographs sum retinal arteriolar and venular calibers were measured with a semi‐automated system. Metabolic syndrome was defined according to the International Diabetes Federation consensus.Results:  A total of 286 (32.9%) participants was diagnosed with metabolic syndrome. Participants with narrower retinal arteriolar caliber were more often diagnosed with metabolic syndrome (odds ratio 1.78, 95% confidence interval 1.02–3.10; lowest vs highest quintile). Additionally adjusting for age, gender, education, smoking and weekly activity, and adding arteriolar and venular caliber simultaneously in the same models did not alter these associations. In the component analyses, participants with narrower retinal arteriolar caliber were more likely to have central obesity, dyslipidaemia or raised blood pressure, and less likely to have raised fasting plasma glucose. The association between wider venular caliber and metabolic syndrome was less pronounced and non‐significant (odds ratio 1.34; 95% confidence interval 0.79–2.38; highest vs lowest quintile).Conclusion:  Retinal arteriolar narrowing and, to a lesser extent, retinal venular dilatation were associated with metabolic syndrome in this Chinese population. These vascular changes, although small in magnitude, may still be important in the pathophysiological mechanisms involved in the metabolic syndrome.

Published: March 2011

AbstractBackground:  Measuring serum 25(OH)D concentration is common in clinical practice despite the questionable reliability of assays.Aims:  The aim of the present study was to examine agreement in 25(OH)D concentrations measured by different assays and laboratories, and consider related clinical implications.Methods:  Serum samples from 813 participants in the Australian Multicentre Study of Environment and Immune Function (the Ausimmune Study) were assayed for 25(OH)D concentration. Duplicate samples from subsets of subjects were sent to different laboratories, two using DiaSorin Liaison (Laboratory A and B) and one using Liquid Chromatography‐Tandem Mass Spectrometry (LC‐MS/MS – selected here as the nominal gold standard). Pairwise within‐assay (both within‐laboratory and between‐laboratories) and between‐assay agreement was examined using Deming regression and Bland‐Altman plots. Common 25(OH)D cut‐points for classification of vitamin D deficiency were used to compare the different assays.Results:  25(OH)D concentrations measured using Liaison were substantially lower at Laboratory A than at Laboratory B (mean bias −11.60 nmol/L, 95% limits of agreement −46.39, 23.18). Both Liaison assays returned much lower 25(OH)D concentrations than LC‐MS/MS (mean bias up to −26.05 nmol/L, 95% limits of agreement of −13.21, 65.31). For Laboratory A participants, 46% (355/765) were classified as vitamin D deficient (25(OH)D <50 nmol/L) using Liaison compared with 17% (128/765) using LC‐MS/MS. For Laboratory B participants, the respective figures were 36% (76/209) and 20% (41/209). Hence, between 1‐in‐5 and 1‐in‐3 participants were misclassified as ‘deficient’.Conclusion:  Bias and variability in 25(OH)D measurements sufficient to affect significantly clinical decision‐making were found both between‐laboratories and between‐assays. The adoption of common standards to allow assay calibration is required urgently.
