Aspirin for primary prevention of cardiovascular disease in diabetes mellitus
Creators: name: Pignone, Michael

Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2010

description: Aspirin is effective for the prevention of cardiovascular events in patients with a history of vascular disease, as so-called secondary prevention. In general populations with no history of previous myocardial infarction or stroke, aspirin also seems useful for primary prevention of cardiovascular events, although the absolute benefits are smaller than those seen in patients with previous cardiovascular disease. Patients with diabetes mellitus are at an increased risk of cardiovascular events, but new trials have raised questions about the benefit of aspirin for primary prevention in patients with this disorder. This Review comprehensively examines the basic pharmacology of aspirin and provides an overview of the randomized, controlled trials of aspirin therapy that have included patients with diabetes mellitus. On the basis of currently available evidence from primary prevention trials, aspirin is estimated to reduce the relative risk of myocardial infarction and stroke by about 10% in patients with diabetes mellitus; however, aspirin also increases the risk of gastrointestinal bleeding. As such, low-dose aspirin therapy (75–162 mg) is reasonable for patients with diabetes mellitus and a 10-year risk of cardiovascular events >10%. Results from upcoming large trials will help clarify the effects of aspirin with greater precision, including whether the benefits differ between men and women.

description: Shape transitions and shape coexistence in the $^{70-98}$Kr region are studied in a unified view with state-of-the-art beyond self-consistent mean field methods based on the Gogny D1S interaction. Beyond mean field effects are taken into account through the exact angular momentum and particle number restoration and the possibility of axial and non-axial shape mixing. The results of the low-lying properties of these isotopes are in good agreement with the experimental data when the triaxial degree of freedom is included. Shape transitions from axial-oblate ($^{70-72}$Kr) to triaxial-prolate ($^{74-78}$Kr) and from spherical-triaxial ($^{86-92}$Kr) to axial-oblate ($^{94-98}$Kr) ground states are obtained. Additionally, low-lying $0^{+}$ excited states and quasi-gamma bands are found showing the richness of the collective structure in this region.

Emerging themes in SecA2-mediated protein export
Creators: name: Braunstein, Miriam

Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2012

description: The conserved general secretion (Sec) pathway carries out most protein export in bacteria and is powered by the essential SecA ATPase. Interestingly, mycobacteria and some Gram positive bacteria possess two SecA proteins: SecA1 and SecA2. In these species, SecA1 is responsible for exporting the majority of proteins whereas SecA2 exports only a subset of substrates and is implicated in virulence. However, despite the impressive body of knowledge on the canonical SecA (SecA1), less is known concerning SecA2 function. Here, we review our current understanding of the different types of SecA2 systems and outline future directions for SecA2 studies.

description: The $γ$-ray spectrum of the low-frequency-peaked BL Lac (LBL) object AP Librae is studied, following the discovery of very-high-energy (VHE; $E>100\,{\rm GeV}$) $γ$-ray emission up to the TeV range by the H.E.S.S. experiment. This makes AP Librae one of the few VHE emitters of the LBL type. The measured spectrum yields a flux of $(8.8 \pm 1.5_{\rm stat} \pm 1.8_{\rm sys}) \times 10^{-12}\ {\rm cm}^{-2} {\rm s}^{-1}$ above 130 GeV and a spectral index of $Γ= 2.65\pm0.19_{\rm stat}\pm0.20_{\rm sys}$. This study also makes use of \textit{Fermi}-LAT, observations in the high energy (HE, E$>$100 MeV) range, providing the longest continuous light curve (5 years) ever published on this source. The source underwent a flaring event between MJD 56306-56376 in the HE range, with a flux increase of a factor 3.5 in the 14-day bin light curve and no significant variation in spectral shape with respect to the low-flux state. While the H.E.S.S., and (low state) \textit{Fermi}-LAT fluxes are in good agreement where they overlap, a spectral curvature between the steep VHE spectrum and the \textit{Fermi}-LAT, spectrum is observed. The maximum of the $γ$-ray emission in the spectral energy distribution is located below the GeV energy range.

description: The analysis of the spatiotemporal picture of particle radiation in relativistic heavy-ion collisions in terms of correlation femtoscopy scales, emission and source functions allows one to probe the character of evolution of the system created in the collision. Realistic models, like the integrated hydrokinetic model (iHKM), used in the present work, are able to simulate the entire evolution process of strongly interacting matter produced in high-energy nuclear collision. The mentioned model describes all the stages of the system's evolution, including formation of the very initial state and its consequent gradual thermalization, hydrodynamic expansion and afterburner hadronic cascade, that can help researchers to figure out the specific details of the process and better understand the formation mechanisms of certain observables. In the current paper we investigate the behavior of the pion and kaon interferometry radii and their connection with emission functions in ultrarelativistic heavy-ion collisions at the Large Hadron Collider within iHKM. We are focusing on the study of the emission time scales at different energies for both particle species (pions and kaons) aiming to get deeper insight into relation of these scales and the peculiarities of the mentioned system's collective expansion and decay with the experimentally observed femtoscopy radii. One of our main interests is the problem of the total system's lifetime estimation based on the femtoscopy analysis.

description: Owing to the detection of mixed modes, subgiant and red-giant stars provide a unique opportunity to probe the complete stellar structure of solar-like stars and to constrain stellar structure and evolution models. KIC 11026764 (Gemma) is a subgiant observed for more than 48 months with around 30 detected modes, a perfectly suited benchmark star. Using our recently developed method to analyse mixed-mode spectra, EGGMiMoSA, and aided by our local minimisation code, PORTE-CLES, we search for stellar models adjusting mixed-mode seismic indicators to precisely constrain the structure of Gemma, a milestone in the context of the PLATO mission. Testing different sets of physical parameters, we aim at unveiling Gemma’s convective history. Combining seismic indicators defined in the EGGMiMoSA framework, namely, Δν_0, Δπ_1, and ε_g with spectroscopic observable (T_eff and log g), and testing different chemical compositions and overshooting amounts, we show that while Gemma is expected to be relatively massive (M ~ 1.17 M⊙), solutions without a convective core during its main-sequence phase are favoured.

description: While image segmentation is crucial in various computer vision applications, such as autonomous driving, grasping, and robot navigation, annotating all objects at the pixel-level for training is nearly impossible. Therefore, the study of unsupervised image segmentation methods is essential. In this paper, we present a pixel-level clustering framework for segmenting images into regions without using ground truth annotations. The proposed framework includes feature embedding modules with an attention mechanism, a feature statistics computing module, image reconstruction, and superpixel segmentation to achieve accurate unsupervised segmentation. Additionally, we propose a training strategy that utilizes intra-consistency within each superpixel, inter-similarity/dissimilarity between neighboring superpixels, and structural similarity between images. To avoid potential over-segmentation caused by superpixel-based losses, we also propose a post-processing method. Furthermore, we present an extension of the proposed method for unsupervised semantic segmentation. We conducted experiments on three publicly available datasets (Berkeley segmentation dataset, PASCAL VOC 2012 dataset, and COCO-Stuff dataset) to demonstrate the effectiveness of the proposed framework. The experimental results show that the proposed framework outperforms previous state-of-the-art methods.

Finding an Appetite for Reducing Food Waste:  Determinants of Commercial Food Waste Management and Diversion in Alberta
Creators: So, Farrah WY
Publisher: name: University of Alberta Library
Year: 2022

Considerable quantities of food waste have been observed globally and minimizing it has the potential to generate significant reductions in the environmental burden of the agri-food sector. The commercial food sector contributes substantially to food waste generation, so understanding the motivations for reducing food waste in this sector is of importance. Pro-environmental behaviours in businesses, have been shown to be influenced by managers' environmental concern, altruism, incentives, and corporate support. However, other factors that may motivate the adoption of strategies to prevent and divert food waste, such as demographic factors, economic beliefs, and collaborative beliefs, have not been addressed in the literature. The aim of this thesis is to investigate factors that influence commercial food businesses in Alberta to engage with behaviours that can reduce waste, firstly by examining the commercial food waste landscape and determining significant demographic and psychological variables that influence behaviour adoption, and secondly by identifying collaborations and policy options that could support food waste reduction. A questionnaire was used to survey representatives from food establishments in Alberta. Binary, fractional, and ordinal probit models were used to analyze the relative contributions of independent variables. Subjective norms, perceived behavioural control, intention, environmental beliefs, collaborative beliefs, business size, and years of experience increased the probability of adopting certain measures to address food waste. Business location influenced the reported amount of food waste produced and the percent of food waste sent to landfill, with businesses in Calgary tending to report the lowest rates. Stronger economic beliefs positively influenced the percent of food waste sent to landfill. Respondents seemed sensitive to financial considerations, showing a low willingness to pay for waste diversion services and perceiving monetary incentives as the most effective instrument to reduce food waste compared to recognition, collaboration, and information provision. There is an opportunity for improvement when it comes to preventing and diverting waste in Alberta. A high level of awareness of waste and a large percentage of respondents being interested in diversion methods indicates that businesses would likely be interested in these solutions if they become available, as long as they are considered cost-effective. This work hopes to contribute to pro-environmental literature and knowledge for policy and industry.

description: We explore the optical birefringence of the nematic binary mixtures 6CB$_{1-x}$7CB$_x$ ($0~\le~x~\le~1$) imbibed into parallel-aligned nanochannels of mesoporous alumina and silica membranes for channel radii of $3.4~\le~R~\le 21.0$ nm. The results are compared with the bulk behavior and analyzed with a Landau-de-Gennes model. Depending on the channel radius the nematic ordering in the cylindrical nanochannels evolves either discontinuously (subcritical regime, nematic ordering field $σ<1/2$) or continuously (overcritical regime, $σ>1/2$), but in both cases with a characteristic paranematic precursor behavior. The strength of the ordering field, imposed by the channel walls, and the magnitude of quenched disorder varies linearly with the mole fraction $x$ and scales inversely proportionally with $R$ for channel radii larger than 4 nm. The critical pore radius, $R_c$, separating a continuous from a discontinuous paranematic-to-nematic evolution, varies linearly with $x$ and differs negligibly between the silica and alumina membranes. We find no hints of preferred adsorption of one species at the channels walls. By contrast, a linear variation of the nematic-to-paranematic transition point $T_{\rm PN}$ and of the nematic ordering field $σ$ vs. $x$ suggest that the binary mixtures of cyanobiphenyls 6CB and 7CB keep their homogeneous bulk stoichiometry also in nanoconfinement, at least for channel diameters larger than $\sim$7 nm.

description: Effective antiretroviral therapy (ART) blunts viraemia, which enables HIV-1-infected individuals to control infection and live long, productive lives. However, HIV-1 infection remains incurable owing to the persistence of a viral reservoir that harbours integrated provirus within host cellular DNA. This latent infection is unaffected by ART and hidden from the immune system. Recent studies have focused on the development of therapies to disrupt latency. These efforts unmasked residual viral genomes and highlighted the need to enable the clearance of latently infected cells, perhaps via old and new strategies that improve the HIV-1-specific immune response. In this Review, we explore new approaches to eradicate established HIV-1 infection and avoid the burden of lifelong ART.

description: With the help of the recently developed SIESTA-PEXSI method [J. Phys.: Condens. Matter \textbf{26}, 305503 (2014)], we perform Kohn-Sham density functional theory (DFT) calculations to study the stability and electronic structure of hexagonal graphene nanoflakes (GNFs) with up to 11,700 atoms. We find the electronic properties of GNFs, including their cohesive energy, HOMO-LUMO energy gap, edge states and aromaticity, depend sensitively on the type of edges (ACGNFs and ZZGNFs), size and the number of electrons. We observe that, due to the edge-induced strain effect in ACGNFs, large-scale ACGNFs' cohesive energy decreases as their size increases. This trend does not hold for ZZGNFs due to the presence of many edge states in ZZGNFs. We find that the energy gaps $E_g$ of GNFs all decay with respect to $1/L$, where $L$ is the size of the GNF, in a linear fashion. But as their size increases, ZZGNFs exhibit more localized edge states. We believe the presence of these states makes their gap decrease more rapidly. In particular, when $L$ is larger than 6.40 $nm$, we find that ZZGNFs exhibit metallic characteristics. Furthermore, we find that the aromatic structures of GNFs appear to depend only on whether the system has $4N$ or $4N+2$ electrons, where $N$ is an integer.

description: We performed a Bayesian analysis of pulsar timing residuals from the NANOGrav pulsar timing array to search for a specific form of stochastic narrow-band signal produced by oscillating gravitational potential in the Galactic halo. Such oscillations arise in models of warm dark matter composed of an ultralight massive scalar field (m\sim 10^{-23} eV), recently considered by Khmelnitsky and Rubakov (2014). In the monochromatic approximation, the stringent upper limit (95% c.l.) on the variable gravitational potential amplitude is found to be Psi_c<1.14 10^{-15}, corresponding to the characteristic strain h_c=2\sqrt{3}Ψ_c < 4 10^{-15} at frequency f=1.75 10^{-8} Hz. In the narrow-band approximation, the upper limit of this background energy density is Ω_{GPB}<1.27 10^{-9} at frequency f=6.2 10^{-9} Hz. These limits are an order of magnitude higher than the expected signal amplitude if the galactic dark matter consists of the ultralight scalar field. The applied analysis of pulsar timing residuals can be used to search for any narrow-band stochastic signals with different correlation properties. As a by-product, parameters of the red noise present in four NANOGrav pulsars (J1713+0747, J2145-0750, B1855+09, J1744-1134) have been evaluated.

description: We report the observation of a dense triangular network of one-dimensional (1D) metallic modes in a continuous and uniform monolayer of MoSe2 grown by molecular-beam epitaxy. High-resolution transmission electron microscopy and scanning tunneling microscopy and spectroscopy (STM/STS) studies show these 1D modes are mid-gap states at inversion domain boundaries. STM/STS measurements further reveal intensity undulations of the metallic modes, presumably arising from the superlattice potentials due to moire pattern and the quantum confinement effect. A dense network of the metallic modes with high density of states is of great potential for heterocatalysis applications. The interconnection of such mid-gap 1D conducting channels may also imply new transport behaviors distinct from the 2D bulk.

Delimitation and identification of crescent butterflies (Nymphalidae: Phyciodes) in Alberta using molecular and morphological techniques
Creators: Wingert, Brittany Denee
Publisher: name: University of Alberta Library
Year: 2022

Species delimitation can be challenging, especially in taxonomic groups that exhibit little morphological divergence. Many techniques and concepts have been developed for detecting species boundaries, and molecular methods are becoming increasingly common. Next generation sequencing techniques make it feasible to obtain hundreds to thousands of genome-wide markers, even for non-model organisms. This can provide powerful insights into species boundaries and the integrity of those boundaries in the presence of gene flow. However, classical taxonomic information, such as morphology, is often excluded from molecular studies, creating a disconnect between delimitation and identification. Integrative and iterative approaches to taxonomy that include morphological data maintain a link between delimitation and identification while providing a more complete understanding of the organisms being studied.

The Phyciodes tharos species group of nymphalid butterflies is currently thought to comprise four species. However, interspecific overlap and intraspecific variability of the wing patterns have resulted in a complicated taxonomic history with uncertainty regarding the level of divergence between species. Discordance of mitochondrial COI with traditional taxonomic identifications has added to this uncertainty but has been attributed to incomplete lineage sorting and contemporary introgression. In this thesis, I used an iterative approach to examine the species limits of this group using genome-wide single nucleotide polymorphisms (SNPs) and the barcoding region of the mitochondrial COI gene. I then quantitatively examined the utility of eighteen morphological characters for identification based on the genomic species lineages. I focused on Alberta, the only region where all four species occur, and no other species of the genus are present.

Genomic SNPs resolved all four species boundaries with strong support for P. tharos (Drury, 1773), P. cocyta (Cramer, 1777), and P. pulchella (Boisduval, 1852). Phyciodes batesii (Reakirt, 1865) did not form a monophyletic clade but did form a distinct cluster in all genomic analyses. Evidence of occasional hybridization and low levels of introgression indicate that these lineages maintain their genomic integrity when in contact. The COI haplotypes were discordant with genomic SNPs but provided evidence of unidirectional mitochondrial gene flow likely due to brood timing and opportunistic mating between species. Morphological characters exhibited extensive intraspecific variation and broad interspecific overlap. None of the character states were strictly diagnostic, but the proportions of character states exhibited for each species are provided as an identification resource.

description: HIV-1 infection typically results from the transmission of a single viral variant, the transmitted/founder (T/F) virus. Studies of these HIV-1 variants provide critical information about the transmission bottlenecks and the selective pressures acting on the virus in the transmission fluid and in the recipient tissues. These studies reveal that T/F virus phenotypes are shaped by stochastic and selective forces that restrict transmission and may be targets for prevention strategies. In this Review, we highlight how studies of T/F viruses contribute to a better understanding of the biology of HIV-1 transmission and discuss how these findings affect HIV-1 prevention strategies.

This is an extension of that proposed Ramer and Rappe [J. Phys. Chem. Sol. 61, 315(2000)], the scheme of which is in want of the explicit incorporation of semi-core states. To compensate this drawback, a kind of fine tuning applied to the non-multi-reference VCA pseudo-potential; the form of the pseudo-potential is slightly modified within the cut-off radius in order that the agreements between the pseudo-potential and all-electron calculations are guaranteed both for semi-core and valence states. The improvement in the present work is validated by atomic and crystalline test calculations for the transferability and the lattice constant estimation.

description: Hepatitis C virus (HCV) is an unusual RNA virus that possesses a striking capacity to persist for life in the majority of infected individuals. In order to persist, HCV must balance viral RNA synthesis and decay in infected cells. In this Review, we focus on interactions between the positive-sense RNA genome of HCV and host RNA-binding proteins and microRNAs (miRNAs) that influence the competing processes of viral RNA synthesis and decay to achieve stable, long-term persistence of the viral genome. We discuss how these processes impact HCV pathogenesis and therapeutic strategies against the virus.

description: A train of action potentials (a spike train) can carry information in both the average firing rate and the pattern of spikes in the train. But can such a spike-pattern code be supported by cortical circuits? Neurons in vitro produce a spike pattern in response to the injection of a fluctuating current. However, cortical neurons in vivo are modulated by local oscillatory neuronal activity and by top-down inputs. In a cortical circuit, precise spike patterns thus reflect the interaction between internally generated activity and sensory information encoded by input spike trains. We review the evidence for precise and reliable spike timing in the cortex and discuss its computational role.

description: Gene-expression profiling has had a considerable impact on our understanding of breast cancer biology, and more recently on clinical care. Two statistical approaches underlie these advancements. Supervised analyses have led to the development of gene-expression signatures designed to predict survival and/or treatment response, which has resulted in the development of new clinical assays. Unsupervised analyses have identified numerous biological signatures including signatures of cell type of origin, signaling pathways, and of cellular proliferation. Included within these biological signatures are the molecular subtypes known as the ‘intrinsic’ subtypes of breast cancer. This classification has expanded our appreciation of the heterogeneity of breast cancer and has provided a way to sub-classify the disease in a manner that might have clinical utility. In this Review, we discuss the clinical utility of gene-expression-based assays and their technical potential as clinical tools vis-a-vis the performance of breast cancer biomarkers that are the current standard of care.

description: Significant advances in our understanding of the in vivo functions of human cells, tissues and immune systems have resulted from the development of mouse strains that are based on severely immunodeficient mice expressing mutations in the interleukin-2 (IL-2) receptor common γ-chain locus. These mouse strains support the engraftment of a functional human immune system and permit detailed analysis of human immune biology, development and functions. In this Review, we discuss recent advances in the development of humanized mice, the lessons learned, the remaining challenges and the promise of using humanized mice for the in vivo study of human immunology.

description: Scegliere di rendere la sua salvezza un fatto tutt’altro che individuale e ammettere che essa passi attraverso un processo di edificazione formativa ‘guidata’ è una trasposizione concreta del modo dantesco di intendere la dimensione culturale. Nelle prime parole che Dante rivolge al poeta latino, l’urgenza di essere salvato si scioglie in un grido, «Miserere di me», che fa coincidere l’inizio del cammino nell’ammissione sincera e autentica del bisogno di misericordia, ovvero con la necessità di riempire un vuoto e soccorrere una condizione di povertà (insita nella radice mĭsĕsr) che richiede di essere colmata. PAROLE CHIAVE: Didattica, salvezza, discepolo, maestro

Fast Membranes Hemifusion via Dewetting between Lipid Bilayers

description: The behavior of lipid bilayer is important to understand the functionality of cells like the trafficking of ions between cells. Standard procedures to explore the properties of lipid bilayer and hemifused states typically use either supported membranes or vesicles. Both techniques have several shortcoming in terms of bio relevance or accessibility for measurements. In this article the formation of individual free standing hemifused states between model cell membranes is studied using an optimized microfluidic scheme which allows for simultaneous optical and electrophysiological measurements. In a first step, two model membranes are formed at a desired location within a microfluidic device using a variation of the droplet interface bilayer (DiB) technique. In a second step, the two model membranes are brought into contact forming a single hemifused state. For all tested lipids, the hemifused state between free standing membranes form within hundreds of milliseconds, i.e. several orders of magnitude faster than reported in literature. The formation of a hemifused state is observed as a two stage process, whereas the second stage can be explained as a dewetting process in no-slip boundary condition. The formed hemifusion states are long living and a single fusion event can be observed when triggered by an applied electric field as demonstrated for monoolein.

description: We report the development of a laboratory-based Rowland-circle monochromator that incorporates a low poer x-ray (bremsstrahlung) tube source, a spherically-bent crystal analyzer (SBCA), and an energy-resolving solid-state detector. This relatively inexpensive, introductory level instrument achieves 1-eV energy resolution for photon energies of 5 keV to 10 keV while also dmeonstrating a net efficiency previously seen only in laboratory monochromators having much coarser energy resolution. Despite the use of only a compact, air-cooled 10 W x-ray tube, we find count rates for nonresonant x-ray emission spectroscopy (XES) comparable to those achived at monochromatized spectroscopy beamlines at synchrotron light sources. For x-ray absorption near edge structure (XANES), the monochromatized flux is small (due to the use of a low-powered x-ray generator) but still useful for routine transmission-mode studies of concentrated samples. These results indicate that upgrading to a standard commercial high-powered line-focused x-ray tube or rotating anode x-ray generator would result in monochromatized fluxes of order 10^6 to 10^7 photons/s with no loss in energy resolution. This work establishes core technical capabilities for a rejuvenation of laboratory-based x-ray spectroscopies that could have special relevance for contemporary research on catalytic or electrical energy storage systems using transition-metal, lanthanide, or noble-metal active species.
