Comparative study on the free radical scavenging mechanism exerted by geraniol and geranylacetone using the combined experimental and theoretical approach
Authors: Stobiecka Agnieszka 
Published: June 2015

AbstractIn the current study the free radical scavenging mechanism of geraniol and geranylacetone has been investigated experimentally and theoretically. Two fragrant acyclic terpenoids were subjected to the ABTS and DPPH assay. Furthermore, the detailed quantum chemical calculations have been undertaken in order to evaluate the possible pathways underlying the radical scavenging activity of selected compounds in the non‐polar and polar media. The density functional theory (DFT) using the hybrid Becke three‐parameter exchange‐correlation functional (B3LYP) was applied. In general both investigated compounds possessed very weak anti‐radical activity at the applied experimental conditions but geranylacetone was significantly more effective as a ABTS•+ and DPPH• scavenger than geraniol. The comparison of DFT‐predicted reaction enthalpies associated with the hydrogen atom transfer mechanism (HAT), the single electron and proton transfer process (SET‐PT) and the sequential proton loss electron‐transfer (SPLET), revealed that the former mechanism should be favoured in geraniol solvated in both the non‐polar and polar media. On the contrary, an anti‐radical activity of geranylacetone in the non‐polar solvent was ascribed to the hydrogen donation mechanism while in the polar solvent it was assigned to the SPLET. According to the computational results the presence of allylic H‐atom (at the position 1C) close to the –OH group seemed to be essential for the observed anti‐radical activity of geraniol. The scavenging ability of geranylacetone was associated with the presence of both allylic and alkylic hydrogens in the close vicinity of the carbonyl functionality.

On the Benefits of Equicorrelation for Portfolio Allocation
Authors: Clements Adam , Scott Ayesha , Silvennoinen Annastiina 
Published: June 2015

AbstractThe importance of modelling correlation has long been recognised in the field of portfolio management, with large‐dimensional multivariate problems increasingly becoming the focus of research. This paper provides a straightforward and commonsense approach toward investigating a number of models used to generate forecasts of the correlation matrix for large‐dimensional problems. We find evidence in favour of assuming equicorrelation across various portfolio sizes, particularly during times of crisis. During periods of market calm, however, the suitability of the constant conditional correlation model cannot be discounted, especially for large portfolios. A portfolio allocation problem is used to compare forecasting methods. The global minimum variance portfolio and Model Confidence Set are used to compare methods, while portfolio weight stability and relative economic value are also considered.

Interprofessional sepsis education module: a pilot study
Authors: Chung Han-Oh , Medina Damien , Fox-Robichaud Alison 
Published: June 2015

ABSTRACTAlthough there is an increasing emphasis on interprofessional collaboration for safer health care systems, there remains a paucity of opportunities for postgraduate trainees to engage in formal interprofessional education (IPE). Current opportunities for interprofessional learning, such as simulation sessions, typically do not provide true IPE because they often utilize actors or confederates as support staff, making residents the only stakeholders in the education experience.Here, we describe a flexible educational module designed to provide genuine IPE for physicians, nurses, and respiratory therapists. We outline how simulation, feedback, and group discussions can be used to teach interprofessional team communication, collaboration, and crew resource management skills—while, at the same time, also teaching a highly relevant medical topic (sepsis management) and thus resulting in learner engagement and motivation.
Association between the emotional status of family caregivers and length of stay in a palliative care unit: A retrospective study

Published: June 2015

ABSTRACTObjective:Several factors associated with referral time to hospice and/or palliative care services have been identified, but there is no literature on the association between these services and the emotional status of the family caregivers (FCs). This article is intended to address that issue.Method:A semistructured interview was employed to collect data for a retrospective cohort study. The primary FCs of terminally ill cancer patients were interviewed at the time of the patient's referral to the palliative care unit. Interview data were combined with patients' medical record data for our analysis. The emotional status of the FCs was categorized into one of three groups according to their responses to the anticipated death of their family member: acceptance, anxious/depressed, and denial/angry. A Cox proportional hazard model was used to examine and identify the factors related to the length of stay (LOS) in the palliative care unit.Results:A total of 198 patient–FC pairs were identified. The median LOS was 18 days. A multivariate analysis with adjustment for potential variables revealed significant differences in LOS according to cancer type and time since cancer diagnosis. The denial/angry FC category was independently associated with a shorter LOS (vs. acceptance, adjusted hazard ratio (aHR) 2.11; 95% confidence interval (CI), 1.11–4.03).Significance of Results:We found that terminally ill cancer patients who were referred late had FCs who were in denial or were angry about the anticipated death of their loved one. The emotional status of FCs should be considered when patients with terminal cancer are referred to palliative care.
Cross-species amplification and characterization of new microsatellite markers for the macaw palm,Acrocomia aculeata(Arecaceae)

Published: June 2015

Microsatellites or simple sequence repeats (SSRs) are useful molecular markers allowing for efficient conservation and sustainable use of genetic resources of plant species. Development of SSR marker system for new species is a very expensive task and time consuming. Cross-species amplification of microsatellite loci is considered as a cost-effective approach for developing microsatellite markers for new species. The aim of this work was to examine the transferability of some SSR markers of twoArecaceaespecies (Astrocaryum aculeatumandElaeis oleifera), inAcrocomia aculeata. Out of the total markers analysed 44% of the markers successfully amplified the genomic DNA inA. aculeata, of which 26% were polymorphic detecting a range of three to eight alleles with an average of 4.5 per locus. High average percentage of polymorphic loci (P= 71.2%) per provenance was obtained within a range of 57–100% detecting genetic variation inA. aculeatagermplasm collections. The polymorphic markers detected a positive inbreeding coefficient (F>0) per locus revealing heterozygote deficiency in the accessions that were analysed. As the cross-amplification was at family level, in which the taxonomic distance is relatively wider between the sources (A. aculeatumandE. oleifera) and the target (A. aculeata) species, the amplification success was relatively low. However, the results are promising and implicated that high cross-amplification success could be achieved at species or genus level inA. aculeata. The markers will contribute towards the domestication of the potential macaw palm through realizing various studies such as population genetics, germplasm characterization, genetic improvement and conservation.
Convergence behaviour and Control in Non-Linear Biological Networks
Authors: Karl Stefan , Dandekar Thomas 
Published: June 2015

AbstractControl of genetic regulatory networks is challenging to define and quantify. Previous control centrality metrics, which aim to capture the ability of individual nodes to control the system, have been found to suffer from plausibility and applicability problems. Here we present a new approach to control centrality based on network convergence behaviour, implemented as an extension of our genetic regulatory network simulation framework Jimena ( http://stefan-karl.de/jimena). We distinguish three types of network control and show how these mathematical concepts correspond to experimentally verified node functions and signalling pathways in immunity and cell differentiation: Total control centrality quantifies the impact of node mutations and identifies potential pharmacological targets such as genes involved in oncogenesis (e.g. zinc finger protein GLI2 or bone morphogenetic proteins in chondrocytes). Dynamic control centrality describes relaying functions as observed in signalling cascades (e.g. src kinase or Jak/Stat pathways). Value control centrality measures the direct influence of the value of the node on the network (e.g. Indian hedgehog as an essential regulator of proliferation in chondrocytes). Surveying random scale-free networks and biological networks, we find that control of the network resides in few high degree driver nodes and networks can be controlled best if they are sparsely connected.
The HRDC domain of E. coli RecQ helicase controls single-stranded DNA translocation and double-stranded DNA unwinding rates without affecting mechanoenzymatic coupling

Published: June 2015

AbstractDNA-restructuring activities of RecQ-family helicases play key roles in genome maintenance. These activities, driven by two tandem RecA-like core domains, are thought to be controlled by accessory DNA-binding elements including the helicase-and-RnaseD-C-terminal (HRDC) domain. The HRDC domain of human Bloom’s syndrome (BLM) helicase was shown to interact with the RecA core, raising the possibility that it may affect the coupling between ATP hydrolysis, translocation along single-stranded (ss)DNA and/or unwinding of double-stranded (ds)DNA. Here, we determined how these activities are affected by the abolition of the ssDNA interaction of the HRDC domain or the deletion of the entire domain in E. coli RecQ helicase. Our data show that the HRDC domain suppresses the rate of DNA-activated ATPase activity in parallel with those of ssDNA translocation and dsDNA unwinding, regardless of the ssDNA binding capability of this domain. The HRDC domain does not affect either the processivity of ssDNA translocation or the tight coupling between the ATPase, translocation and unwinding activities. Thus, the mechanochemical coupling of E. coli RecQ appears to be independent of HRDC-ssDNA and HRDC-RecA core interactions, which may play roles in more specialized functions of the enzyme.
