AbstractPalm oil that has been interesterified to produce a higher proportion of palmitic acid (16:0) in the sn‐2 position reduces postprandial lipemia in young, normolipidemic men and women, but effects in older subjects with higher fasting triacylglycerol (TAG) concentrations are unknown. We tested the hypothesis that high‐fat meals rich in interesterified palm olein (IPO) decrease lipemia and alter plasma lipoprotein fraction composition compared to native palm olein (NPO) in men aged 40–70 years with fasting TAG concentrations ≥1.2 mmol/L. Postprandial changes in plasma lipids following meals containing 75 g fat (NPO and IPO) were compared using a randomized, double‐blind crossover design (n = 11). Although there were no significant differences in plasma TAG concentrations between meals over the total 6‐h postprandial measurement period, IPO resulted in a decreased plasma TAG response during the first 4 h of the postprandial period (iAUC 1.65 mmol/L h, 95 % CI 1.01–2.29) compared to NPO (iAUC 2.33 mmol/L h, 95 % CI 1.58–3.07); meal effect P = 0.024. Chylomicron fraction TAG concentrations at 4–6 h were slightly reduced following IPO compared to NPO [NPO−IPO mean difference 0.29 mmol/L (95 % CI −0.01–0.59), P = 0.055]. There were no differences in IDL fraction TAG, cholesterol or apolipoprotein B48 concentrations following IPO compared with NPO. In conclusion, consuming a meal containing palm olein with a higher proportion of 16:0 in the sn‐2 position decreases postprandial lipemia compared to native palm olein during the early phase of the postprandial period in men with higher than optimal fasting triacylglycerol concentrations.
Distribution of Glycolipid and Unsaturated Fatty Acids in Human Hair
Authors: Takahashi Toshie , Yoshida Satoshi 
Published: August 2014

AbstractIt has been recognized that human hair lipids play crucial roles in the integrity of cells and matrices, while the details of distribution and structure of the minor lipids are hardly known. Here we investigated the lipids at the hair surface, at the interface between cuticle and cortex and in the interior of hair (cortex, medulla and melanin granules). Hair lipids and fatty acids and their metabolites were detected and characterized by using infrared spectroscopy and several mass spectrometry techniques (FTIR, ToF–SIMS, GCMS, and ESI–MS). As a result, it was found that unsaturated fatty acids were present more in the cortex of hair than at the hair surface. At the interface between cuticle and cortex, it is suggested that steryl glycoside‐like lipids containing N‐acetylglucosamine were present, and contributing to the adhesion between the cuticle and cortex of hair. Oxidative metabolites derived from integral fatty acids such as linoleic and alpha‐linolenic acids were found in the hair bulb and melanin granules. Especially the oxidative metabolites of alpha‐linolenic acid were integrated into the lipids non‐covalently and tightly bound to melanin granules (namely, melanin lipids) and suggested as being involved in the biosynthetic processes of melanosome.
Applying a Darwinian model to the dynamic capabilities view: Insights and issues
Authors: Galvin Peter , Rice John , Liao Tung-Shan 
Published: August 2014

AbstractThe Darwinian logic of evolution occurring via the mechanisms of variation, selection and retention provides a possible theoretical framework from which to further develop the dynamic capabilities view. Presently, criticized for lacking a theoretical foundation and featuring a degree of confusion concerning how it aligns with the resource-based view, the dynamic capabilities view would benefit from greater clarity concerning its assumptions, theoretical base and the development of a series of testable predictions. We test elements of a potential Darwinian style framework through variation-focused hypotheses using panel data for 190 Australian service firms. Our results highlight the importance of market development as a basis for variation, however, the impact of dynamic capabilities upon a likely antecedent of selection was not clear and highlighted a nuanced relationship between capability development, market development and sales growth in an small-and-medium-sized enterprise environment. We conclude that applying a Darwinian lens to the dynamic capabilities view is challenging without longer time series data and additional measures, but such an approach remains theoretically attractive and further investigation may help clarify how we conceptualize the relationship between the dynamic capabilities view and resource-based view.

SUMMARYThis paper summarizes a study initiated by the Turkish General Directorate of Agricultural Research and ICARDA/CIMMYT Wheat Improvement Program on the adoption of five new winter and spring wheat varieties developed and released by the Turkish national breeding program and through international collaboration in the past 10 years. The study results are based on a survey of 781 households selected randomly in the Adana, Ankara, Diyarbakir, Edirne, and Konya provinces of Turkey. The five new wheat varieties are compared to old improved varieties released prior to 1995 that are also still grown by farmers. Technical and biological indicators of impacts including crop productivity are measured to determine the impact of these varieties. Yield stability is assessed by comparing average yields in normal, good and dry years and by comparing the coefficients of variation of yields by variety. Profitability is measured by the gross margin generated per unit of land. Household income from wheat and for all economic activities are estimated and compared between adopters and non-adopters. Adopters of the new varieties have higher per-capita income than non-adopters as compared to the same group using old varieties. However, the overall impact of the improved varieties is generally low, mainly due to their low adoption levels. Farmers’ knowledge and perception of certain variety characteristics and unavailability of adequate and timely seed are the main reasons. Increasing adoption has the potential to improve household income and this requires revising wheat impact pathway to achieve the expected impact.
The importance of the gestation period for welfare of lambs: maternal stressors and lamb vigour and wellbeing

Published: August 2014

SUMMARYThe prenatal period is of critical importance in defining how individuals respond to their environment throughout life. Stress experienced by pregnant females has been shown to have detrimental effects on offspring behaviour, health and productivity. The sheep has been used extensively as a model species to inform human studies. However, in the farmed environment, the consequences for the lamb of the imposition of prenatal stresses upon the ewe have received much less attention. The stressors that pregnant ewes are most frequently exposed to include sub-optimal nutrition and those related to housing, husbandry and environment which may be either acute or chronic. A systematic review of the literature was adopted to identify material which had production-relevant maternal stressors and lamb outcomes. The current review focussed upon the lamb up to weaning around the age of 100 days and the results clearly demonstrate that stressors imposed upon the ewe have implications for offspring welfare and performance. Maternal under-nutrition (UN) in the last third of pregnancy consistently impaired lamb birth-weight and subsequent vigour and performance, while earlier UN had a variable effect on performance. Feeding the ewe above requirements did not have positive effects on lamb performance and welfare. Social and husbandry stressors such as transport, shearing, mixing and physiological treatments designed to mimic acute stress which would be considered disadvantageous for the ewe had positive or neutral effects for the lamb, highlighting a potential conflict between the welfare of the ewe and her lamb. This review also identified considerable gaps in knowledge, particularly in respect of the impact of disease upon the ewe during pregnancy and interactions between different stressors and the responses of ewe and lamb.
Two new or misunderstood species related to Verrucaria praetermissa (Verrucariaceae, lichenized Ascomycota)
Authors: ORANGE Alan 
Published: August 2014

AbstractThe taxonomy of species related to Verrucaria praetermissa is investigated using morphological and molecular data. Verrucaria devensis is closely related to V. praetermissa but distinguished by the darker colour, the thinner and more uneven thallus, and the ITS sequence. This species is based on Leucocarpopsis devensis G. Salisb., which was originally described as the type species of a monotypic genus differing from Verrucaria by the absence of dark pigment. Verrucaria lapidicola is a new species from stones in non-aquatic situations; it is related to V. praetermissa and V. elaeina but differs in the very thin thallus and ITS sequence.
Melaspilea tucumana, a new gall-forming lichenicolous fungus from the tropical Andes in Bolivia
Authors: FLAKUS Adam , ETAYO Javier , KUKWA Martin 
Published: August 2014

AbstractThe new obligately lichenicolous fungus, Melaspilea tucumana Flakus, Etayo & Kukwa, inhabiting thalli of saxicolous Pertusaria s. lat. is described from Tucumano-Boliviano vegetation in Bolivia. The species is characterized by the gall formation and superficial, lirelliform to branched, aggregated apothecioid ascomata with widely exposed discs. The ascomata of M. tucumana are initially perithecioid and immersed in the host thallus, but become superficial and apothecioid when mature, and thus resemble the genus Buelliella. This may suggest the placement of the new species in Dothideomycetes.
Extended phylogeny and a revised generic classification of thePannariaceae(Peltigerales, Ascomycota)

Published: August 2014

AbstractWe estimated phylogeny in the lichen-forming ascomycete familyPannariaceae. We specifically modelled spatial (across-site) heterogeneity in nucleotide frequencies, as models not incorporating this heterogeneity were found to be inadequate for our data. Model adequacy was measured here as the ability of the model to reconstruct nucleotide diversity per site in the original sequence data. A potential non-orthologue in the internal transcribed spacer region (ITS) ofDegelia plumbeawas observed. We propose a revised generic classification for thePannariaceae, accepting 30 genera, based on our phylogeny, previously published phylogenies, as well as available morphological and chemical data. Four genera are established as new:Austroparmeliella(for the ‘Parmeliella’laceratagroup), Nebularia(for the ‘Parmeliella’incrassatagroup),Nevesia(for ‘Fuscopannaria’sampaiana), andPectenia(for the ‘Degelia’plumbeagroup). Two genera are reduced to synonymy,Moelleropsis(included inFuscopannaria) andSantessoniella(non-monophyletic; type included inPsoroma).Lepidocollema, described as monotypic, is expanded to include 23 species, most of which have been treated in the ‘Parmeliella’marianagroup.HomotheciumandLeightoniella, previously treated in theCollemataceae, are here referred to thePannariaceae. We propose 41 new species-level combinations in the newly described and re-circumscribed genera mentioned above, as well as inLeciophysmaandPsoroma.

These species were found during a study aiming at an inventory of the lichen biodiversity of the Cerrado forests in the area, and were not found during earlier ecological studies in the Caatinga forests in the same area.Stirtonia lucidais the first species assigned to this genus which occasionally has some longitudinal septa in the ascospores. Such specimens might be confused withCryptotheciaspecies.
Determination of some population parameters of the veined rapa

Published: August 2014

The veined rapa whelk is one of the most important invasive species in the
Black Sea ecosystem since the 1940s. Following its introduction to the Black
Sea, it destroyed most of the bivalve populations, mainly the Mediterranean
mussel and oysters. However, the veined rapa whelk has commercial importance
for the Black Sea fisheries as an alternative product. In this study, we
aimed to determine some population parameters of the veined rapa whelk based
on indirect ageing through length–frequency data by using the Bhattacharya
method. We collected 1704 specimens by dredging along the coasts of Samsun
Province in the Central Black Sea in 2011 from June to November. The age of
the population varied from 0 to 6. Von Bertalanffy growth parameters were
estimated as L∞ = 112.35 mm, k = 0.310, t0 = −0.486 and W∞ = 243.94 g. Mean length and weight, length–weight relationship,
mortality and exploitation rates were derived as
L = 56.80 ± 0.36 mm, W = 45.67 ± 0.89 g,
W = 0.0006 L2.719, Z = 0.96,
M = 0.57, F = 0.39 and
E = 0.40, respectively.
DEVELOPMENT OF COVERAGE WITH EVIDENCE DEVELOPMENT FOR MEDICAL TECHNOLOGIES IN SWITZERLAND FROM 1996 TO 2012
Authors: Brügger Urs , Ruckstuhl Andreas , Horisberger Bruno , Gratwohl Alois 
Published: August 2014

Objectives: The aim of this study was to assess incidence, time frame, and outcome of “Coverage with Evidence Development” (CED) decisions in the Swiss Basic Health Insurance scheme.Methods: Analysis of all controversial medical technologies submitted to review by the Swiss Federal Office of Public Health (FOPH) from 1996 to 2012 with focus on decisions with constraints. Description of types of technology, type of initial decision, duration of evaluation period, final decision, and search for potential factors associated with changes over time.Results: Forty-five (37.5 percent) of 120 controversial health technologies were classified as “yes, in evaluation, reimbursed” for a certain period of time and thirty-five (29.2 percent) as “no, in evaluation, not reimbursed” by the Federal Department of Home Affairs from 1996 to 2012. The rate of CED decisions ranged between zero and nine per year and was influenced by type of technology and calendar year. Forty-four of forty-five decisions were subject to further restrictions, to a “center or a specialist” (76 percent), “indications” (49 percent), “registry” (31 percent), or “other” (49 percent). The time to a final decision ranged from 1.5 to 11 years (median, 6 years). No factors associated with initial decision and final outcome could be identified.Conclusions: CED as a reality in Switzerland might have enabled patients to obtain access to promising technologies early in their life cycle. CED might have acted as a trigger to a successful implementation of a comprehensive national registry. The lack of qualitative data stresses the urgent need for evaluation of the HTA decisions and their impact on patient outcome and costs.
TECHNIQUES FOR DIAGNOSING OSTEOPOROSIS: A SYSTEMATIC REVIEW OF COST-EFFECTIVENESS STUDIES
Authors: Minniti Davide , Davini Ottavio , Gualano Maria Rosaria , Gianino Maria Michela 
Published: August 2014

Objectives:The study question was whether dual-energy X-ray absorptiometry (DXA) alone is more cost-effective for identifying postmenopausal women with osteoporosis than a two-step procedure with quantitative ultrasound sonography (QUS) plus DXA. To answer this question, a systematic review was performed.Methods:Electronic databases (PubMed, INAHTA, Health Evidence Network, NIHR, the Health Technology Assessment program, the NHS Economic Evaluation Database, Research Papers in Economics, Web of Science, Scopus, and EconLit) were searched for cost-effectiveness publications. Two independent reviewers selected eligible publications based on the inclusion/exclusion criteria. Quality assessment of economic evaluations was undertaken using the Drummond checklist.Results:Seven journal articles and four reports were reviewed. The cost per true positive case diagnosed by DXA was found to be higher than that for diagnosis by QUS+DXA in two articles. In one article it was found to be lower. In three studies, the results were not conclusive. These articles were characterized by the differences in the types of devices, parameters and thresholds on the QUS and DXA tests and the unit costs of the DXA and QUS tests as well as by variability in the sensitivity and specificity of the techniques and the prevalence of osteoporosis.Conclusions:The publications reviewed did not provide clear-cut evidence for drawing conclusions about which screening test may be more cost-effective for identifying postmenopausal women with osteoporosis.
Frugivorous weevils are too rare to cause Janzen–Connell effects in New Guinea lowland rain forest
Authors: Ctvrtecka Richard , Sam Katerina , Brus Erik , Weiblen George D. , Novotny Vojtech 
Published: August 2014

Abstract:A community of frugivorous weevils was studied by quantitative rearing of 57 weevil species represented by 10485 individuals from 326 woody plant species in lowland rain forest in Papua New Guinea. Only fruits from 35% of plant species were attacked by weevils. On average, weevils were reared from only 1 in 33 fruits and 1 kg of fruit was attacked by 2.51 individuals. Weevil host specificity was relatively high: 42% of weevil species fed on a single plant genus, 19% on a single plant family and only 16% were reared from more than one family. However, monophagous specialists represented only 23% of all reared individuals. The average 1 kg of fruits was infested by 1.84 individuals of generalist weevils (feeding on allogeneric or allofamilial host species), 0.52 individual of specialists (feeding on a single or several congeneric species), and 0.15 individual of unknown host specificity. Large-seeded fruits with thin mesocarp tended to host specialist species whereas those with thick, fleshy mesocarp were often infested with both specialists and generalists. Weevils tended to avoid small-seeded, fleshy fruits. The low incidence of seed damage (3% of seeds) suggests that weevils are unlikely to play a major role in regulating plant populations via density-dependent mortality processes outlined by the Janzen–Connell hypothesis.

ABSTRACTThe present study was conducted to determine whether anxiety among community-dwelling elders is associated with cognitive decline over a period of one year as well as to verify whether there are sex differences in the association between anxiety and cognitive decline. Participants (n=1942) were community-dwelling adults aged 65–96 years assessed at study entry (T0) and one year later (T1). Anxiety was identified with a semi-structured interview and cognitive functioning was assessed using the Mini-Mental State Examination. Results revealed that the presence of a clinically significant anxiety disorder did not predict cognitive decline in men and women. Subclinical anxiety symptoms predicted cognitive decline in women only. Moreover, for men, the presence of symptoms from at least two anxiety disorders predicted cognitive decline. For women, cognitive decline was predicted by the presence of symptoms from one anxiety disorder only. Overall, the results illustrate the role of anxiety in cognitive decline in community-dwelling older adults.

RÉSUMÉL'insuffisance cardiaque (IC) est fréquente chez les résidents en soins de longue durée (SLD), et peut représenter 40 pour cent des transferts aux soins aigus. Des lignes directrices de l’IC de la Société canadienne de cardiologie approuvent les traitements standards, mais les résidents de SLD sont moins susceptibles de recevoir un traitement.* Cette étude qualitative a utilisé des groupes de discussion pour explorer les perceptions, de 18 médécins et infirmières praticiennes dans trois foyers de l’Ontario, des pratiques de soins de l’IC et les défis de SLD. Par exemple, les participants ont rapporté les défis concernant aptitudes diagnostiques et les connaissances procédurales de l’IC. Ils ont également identifié la nécessité de la collaboration interprofessionnelle et la clarification des rôles pour améliorer les soins et les résultats de l’IC. Pour résoudre ces problèmes, les interventions multi-modales et l'enseignement de chevet sont requis. Le leadership a été considéré comme essentielle pour améliorer les soins de l’IC. Plusieurs préoccupations ont surgi concernant les lacunes dans les connaissances et les déficits cliniques chez les fournisseurs de soins primaires qui traitent l'insuffisance cardiaque chez les résidents de SLD. Pour améliorer les soins de l'IC à long terme, des solutions éducatives et interprofessionnelles multi-modales et cliniquement ciblées sont nécessaires.
