Overexpression of CUGBP1 in Skeletal Muscle from Adult Classic Myotonic Dystrophy Type 1 but Not from Myotonic Dystrophy Type 2

Myotonic dystrophy type 1 (DM1) and type 2 (DM2) are progressive multisystemic disorders caused by similar mutations at two different genetic loci. The common key feature of DM pathogenesis is nuclear accumulation of mutant RNA which causes aberrant alternative splicing of specific pre-mRNAs by altering the functions of two RNA binding proteins, MBNL1 and CUGBP1. However, DM1 and DM2 show disease-specific features that make them clearly separate diseases suggesting that other cellular and molecular pathways may be involved. In this study we have analysed the histopathological, and biomolecular features of skeletal muscle biopsies from DM1 and DM2 patients in relation to presenting phenotypes to better define the molecular pathogenesis. Particularly, the expression of CUGBP1 protein has been examined to clarify if this factor may act as modifier of disease-specific manifestations in DM. The results indicate that the splicing and muscle pathological alterations observed are related to the clinical phenotype both in DM1 and in DM2 and that CUGBP1 seems to play a role in classic DM1 but not in DM2. In conclusion, our results indicate that multisystemic disease spectrum of DM pathologies may not be explained only by spliceopathy thus confirming that the molecular pathomechanism of DM is more complex than that actually suggested.
Rift Valley Fever Risk Map Model and Seroprevalence in Selected Wild Ungulates and Camels from Kenya

Since the first isolation of Rift Valley fever virus (RVFV) in the 1930s, there have been multiple epizootics and epidemics in animals and humans in sub-Saharan Africa. Prospective climate-based models have recently been developed that flag areas at risk of RVFV transmission in endemic regions based on key environmental indicators that precede Rift Valley fever (RVF) epizootics and epidemics. Although the timing and locations of human case data from the 2006–2007 RVF outbreak in Kenya have been compared to risk zones flagged by the model, seroprevalence of RVF antibodies in wildlife has not yet been analyzed in light of temporal and spatial predictions of RVF activity. Primarily wild ungulate serum samples from periods before, during, and after the 2006–2007 RVF epizootic were analyzed for the presence of RVFV IgM and/or IgG antibody. Results show an increase in RVF seropositivity from samples collected in 2007 (31.8%), compared to antibody prevalence observed from 2000–2006 (3.3%). After the epizootic, average RVF seropositivity diminished to 5% in samples collected from 2008–2009. Overlaying maps of modeled RVF risk assessments with sampling locations indicated positive RVF serology in several species of wild ungulate in or near areas flagged as being at risk for RVF. Our results establish the need to continue and expand sero-surveillance of wildlife species Kenya and elsewhere in the Horn of Africa to further calibrate and improve the RVF risk model, and better understand the dynamics of RVFV transmission.
Effects of Olmesartan and Azilsartan on Albuminuria and the Intrarenal Renin-Angiotensin System.

Purpose Olmesartan and azilsartan decrease blood pressure more effectively than other angiotensin receptor blockers (ARBs). ARBs additionally decrease the urinary albumin to creatinine ratio (UACR), a urinary albumin marker, and urinary angiotensinogen (u-AGT), an intrarenal renin-angiotensin system activity marker. We examined the effects of these ARBs on blood pressure, UACR, and u-AGT in patients with uncontrolled hypertension. Methods Patients with uncontrolled hypertension treated with conventional ARBs, excluding olmesartan and azilsartan, for over 8 weeks were enrolled. We randomly switched patients from their prior ARBs to either olmesartan or azilsartan, and followed them for 24 weeks. Results Systolic blood pressure (SBP), diastolic blood pressure (DBP), and central systolic blood pressure (cSBP) significantly decreased at 24 weeks. UACR and u-AGT also decreased at 24 weeks in both groups. There were no significant differences in SBP, DBP, cSBP, UACR, or u-AGT between the groups. Therefore, we combined both groups for further analyses. After combining, SBP (160.5 ± 16.4 to 139.6 ± 15.6 mm Hg, P < 0.0001), DBP (88.4 ± 13.7 to 80.7 ± 13.2 mm Hg, P = 0.008), cSBP (167.4 ± 20.8 to 146.6 ± 24.6 mm Hg, P < 0.0001), UACR (13.8 to 9.0 mg/g Cre, P = 0.0096), and u-AGT (4.13 to 2.32 μg/g Cre, P = 0.0074) significantly decreased at 24 weeks. Patients with microalbuminuria (UACR ≥ 30 mg/g Cre) had significantly greater ΔUACR (-39.4 vs 0.27, P = 0.0024) and Δu-AGT (-11.9 vs -0.61, P = 0.0235) than patients without microalbuminuria. The changes in u-AGT were significantly associated with changes in UACR (r = 0.411, P = 0.046); however, there was no significant relationship between the changes in u-AGT and those in SBP or DBP. Conclusion Olmesartan and azilsartan decreased blood pressure, UACR, and u-AGT more than the other ARBs, and exerted depressor and renoprotective effects.
Dietary Micronutrient Intake in Peritoneal Dialysis Patients: Relationship with Nutrition and Inflammation Status

♦ Objective: To compare dietary intake of micronutrients by peritoneal dialysis (PD) patients according to their nutrition and inflammatory statuses. ♦ Design: This cross-sectional study evaluated 73 patients using subjective global assessment, 24-hour dietary recall, and markers of inflammation [C-reactive protein (CRP), tumor necrosis factor α, and interleukin 6]. ♦ Results: Half the patients had an inadequate micronutrient intake. Compared with dietary reference intakes, malnourished patients had lower intakes of iron (11 mg) and of vitamins C (45 mg) and B6 (0.8 mg). Malnourished and well-nourished patients both had lower intakes of sodium (366 mg, 524 mg respectively), potassium (1555 mg, 1963 mg), zinc (5 mg, 7 mg), calcium (645 mg, 710 mg), magnesium (161 mg, 172 mg), niacin (8 mg, 9 mg), folic acid (0.14 mg, 0.19 mg), and vitamin A (365 μg, 404 μg). Markers of inflammation were higher in malnourished than in well-nourished subjects. Compared with patients in lower quartiles, patients in the highest CRP quartile had lower intakes (p < 0.05) of sodium (241 mg vs 404 mg), calcium (453 mg vs 702 mg), vitamin B2 (0.88 mg vs 1.20 mg), and particularly vitamin A (207 μg vs 522 μg). ♦ Conclusions: Among PD patients, half had inadequate dietary intakes of iron, zinc, calcium and vitamins A, B6, C, niacin, and folic acid. Lower micronutrient intakes were associated with malnutrition and inflammation. Patients with inflammation had lower intakes of sodium, calcium, and vitamins A and B2. Micronutrient intake must be investigated in various populations so as to tailor adequate supplementation.
Role of social interactions in dynamic patterns of resource patches and forager aggregation

The dynamics of resource patches and species that exploit such patches are of interest to ecologists, conservation biologists, modelers, and mathematicians. Here we consider how social interactions can create unique, evolving patterns in space and time. Whereas simple prey taxis (with consumable prey) promotes spatial uniform distributions, here we show that taxis in producer–scrounger groups can lead to pattern formation. We consider two types of foragers: those that search directly (“producers”) and those that exploit other foragers to find food (“scroungers” or exploiters). We show that such groups can sustain fluctuating spatiotemporal patterns, akin to “waves of pursuit. ” Investigating the relative benefits to the individuals, we observed conditions under which either strategy leads to enhanced success, defined as net food consumption. Foragers that search for food directly have an advantage when food patches are localized. Those that seek aggregations of group mates do better when their ability to track group mates exceeds the foragers’ food-sensing acuity. When behavioral switching or reproductive success of the strategies is included, the relative abundance of foragers and exploiters is dynamic over time, in contrast with classic models that predict stable frequencies. Our work shows the importance of considering two-way interaction—i.e., how food distribution both influences and is influenced by social foraging and aggregation of predators.
University of Padua at CLEF 2002: Experiments to Evaluate a Statistical Stemming Algorithm

In Information Retrieval (IR), stemming is used to reduce variant word forms to common root. The assumption is that if two words have the same root, then they represent the same concept. Hence stemming permits a IR system to match query and document terms which are related to a same meaning but which can appear in dierent morphological variants. In this paper we will report our participation in CLEF 2002 Italian monolingual task, whose aim was to evaluate a statistical stemming algorithm based on link analysis. Considering that a word is formed by a prefix (stem) and a sux, the key idea is that the interlinked prefixes and suxes form a community of substrings. Hence discovering these communities means searching for the best word splits which give the best word stems. The results show that stemming improves the IR eectiveness. They also show that eectiveness level of our algorithm, which does not incorporate any heuristics nor linguistic knowledge, is comparable to that of an algorithm based on a-priori linguistic knowledge. This is an encouraging result, particularly in a multi-lingual context.
The extrusion test and sensory perception revisited: Some comments on generality and the effect of measurement temperature.

Relations between sensory perception, extrusion and fracture in shear, extension and compression are examined. Gelatin-based gels are perceived as less firm and less hard than expected based on their mechanical properties compared to polysaccharide gels that have the same mechanical properties at room temperature but melt well above body temperature, underlying the importance of the measurement temperature for gels that melt during mastication. Correlations between parameters from extrusion and compression, extension and shear are verified using mixed polysaccharide gels. PRACTICAL APPLICATIONS We previously reported a high correlation between several sensory attributes and parameters from an extrusion test. The extrusion test showed the most robust correlation, and could be used to assess samples at both extremes of the texture range with respect to elasticity, for example, both samples that could not be extended as their very low elasticity led to their fracture during handling, as well as samples that could not be fractured in compression. Here, we reexamine the validity of the relations reported. We demonstrate the generality of the relations between large deformation tests and extrusion, but the findings underscore the need to take into account the measurement temperature for samples that melt during mastication when correlating instrumental parameters with sensory perception.
Screening for Diabetes Mellitus among Tuberculosis Patients: Findings from a Study at a Tertiary Hospital in Lusaka, Zambia

Background Diabetes mellitus (DM) is known to be associated with active tuberculosis (TB). Zambia is a low-income sub-Saharan African country with a high TB burden and increasing numbers of newly diagnosed DM patients. Materials and Methods This was an observational study conducted at the University Teaching Hospital in Lusaka, Zambia, from October 2014 to February 2016. Adult patients with active TB were screened for DM. Results A total of 127 individuals were enrolled in the study. Six patients (5%) were found to have diabetes. Of these, three had a prior diagnosis of diabetes and were on medication while three were newly diagnosed. Low education level was significantly associated with DM (p=0.001; 95% CI 0.001–0.148). Conclusion The prevalence of DM among individuals with smear positive TB in our study population was similar to that of the general population in Zambia.
A Sequential Non-Parametric Multivariate Two-Sample Test

Given samples from two distributions, a non-parametric two-sample test aims at determining whether the two distributions are equal or not, based on a test statistic. Classically, this statistic is computed on the whole data set, or is computed on a subset of the data set by a function trained on its complement. We consider methods in a third tier, so as to deal with large (possibly infinite) data sets, and to automatically determine the most relevant scales to work at, making two contributions. First, we develop a generic sequential non-parametric testing framework, in which the sample size need not be fixed in advance. This makes our test a truly sequential non-parametric multivariate two-sample test. Under information theoretic conditions qualifying the difference between the tested distributions, consistency of the two-sample test is established. Second, we instantiate our framework using nearest neighbor regressors, and show how the power of the resulting two-sample test can be improved using Bayesian mixtures and switch distributions. This combination of techniques yields automatic scale selection, and experiments performed on challenging data sets show that our sequential tests exhibit comparable performances to those of state-of-the-art non-sequential tests.
Exchange Market Pressure in China: A Re-Examination Based on Girton-Roper Monetary Model

For China’s inefficient foreign exchange market, as the foreign exchange market is difficult to clear in time, so the foreign exchange market pressure always exists. Therefore, the in-depth study and discussion of China’s foreign exchange market pressure issue has important practical significance. This paper applies Lance Girton and Don Roper’s monetary model of exchange market pressure to China’s experience. The purpose of this paper is mainly to test whether the excess supply of money in China can be absorbed by some combination of the change in exchange rate and the change in foreign reserves. The results of empirical analysis indicate that the basic theoretical proposition is accordant with the practice.
A comparative view on the potential acting on an electron in a molecule and the electrostatic potential through the typical halogen bonds

This work considers the features of the electrostatic potential (ESP), and the potential acting on an electron in a molecule (PAEM) for the series of isolated dihalide molecules and for their molecular complexes. The joint analysis of these functions enriches the vision of atomic predispositions to the halogen bond formation and reveals details for their characterization. The account for the exchange‐correlation interaction in PAEM retains the specific anisotropy of the ESP, which is commonly used for the halogen bonding explanation within σ‐hole concept. Along the halogen bonds, the curvatures of PAEM and ESP functions are opposite. Being jointly mapped on the closed isosurfaces of the reduced density gradient, placed between bound atoms, they are significantly differed from the side facing the halogen atom and from the side looking at the electron donor atom. © 2017 Wiley Periodicals, Inc.
Multicommodity network flows - A survey

This report aims at a comprehensive survey of the literature dealing with the multicommodity flow problem. This problem arises naturally in network modelling wherever commodities, vehicles, or messages are to be shipped or transmitted from certain nodes of an underlying network to some others. Recent applications of mathematical programming techniques to traffic equilibrium problems in transportation studies as well as computer networks analysis has renewed considerable interest in this problem. This report discusses solution techniques for both linear and nonlinear flow problems. The former includes decomposition, partitioning, compact inverse methods, and primal-dual algorithms. Described is a variety of feasible direction methods for the latter. The report concludes by giving applications and computational experience for both types of problems.
Variation of surface roughness, micro-hardness and friction behaviour during sheet-metal forming

The aim of the research described in this paper is to analyse the evolution of the main surface parameters values and friction coefficient value due to the sheet deformation. Frictional properties of the deep-drawing quality steel sheets were investigated using the strip drawing test under both dry and lubricated conditions. An increase in the plastic deformation of sheets in the range of true strain between 0 to 0.28 caused an increase in the value of amplitude roughness parameters Ra, Rp, Rt, measured along the rolling direction of the sheet metal and perpendicular to this direction. The character of frictional phenomena of the deformed sheets is a complex function of sheet directional topography, formed by pre-straining and strain-hardening phenomena. It was also found that owing to the strain-hardening phenomenon the micro-hardness of the sheet increased with the sheet deformation. However, this relation was near linear.
Bouncing and 3D printable hybrids with self-healing properties

Conventional composites often do not represent true synergy of their constituent materials. This is particularly evident in biomaterial applications where devices must interact with cells, resist cyclic loads and biodegrade safely. Here we propose a new hybrid system, with co-networks of organic and inorganic components, resulting in unprecedented mechanical properties, including “bouncy” elasticity and intrinsic ability to self-heal autonomously. They are also developed as new ‘inks’ that can be directly 3D printed. A hybrid is different from a nanocomposite because the components are indistinguishable from each other at the nanoscale and above. The properties are generated by a novel methodology that combines in situ cationic ring-opening polymerisation with sol–gel, creating silica/poly(tetrahydrofuran)/poly(e-caprolactone) hybrids with molecular scale interactions and covalent links. Cartilage is notoriously difficult to repair and synthetic biomaterials have yet to mimic it closely. We show that 3D printed hybrid scaffolds with pore channels of ∼200 μm mimic the compressive behaviour of cartilage and provoke chondrocytes to produce markers integral to articular cartilage-like matrix. The synthesis method can be applied to different organic sources, leading to a new class of hybrid materials.
outputs Exploring pathways across stories Conference Item

This paper describes a method for supporting the exploration of a collection of documents organized as a hypertext by investigating relations between documents along userspecified paths. The approach is demonstrated on a corpus of stories about the World War Two activities of the British Government Code and Cypher School at Bletchley Park. Each story is described by one or more events and annotated in terms of domain ontologies. A pathway in the document space is a sequence of events in which adjacent events share common binding concepts. The criteria for selecting the pathway include a measure of the adherence to the user-specified part of the document space and the mutual information between adjacent documents calculated from their annotations.
Effects of Long-Term Type I Interferon on the Arterial Wall and Smooth Muscle Progenitor Cells Differentiation

Objective— Patients with systemic lupus erythematosis are at risk for premature atherosclerosis and half of the patients with systemic lupus erythematosis have elevated type I interferon (IFN-I) levels. We hypothesized that IFN-I would induce premature atherosclerosis by increasing the number of smooth muscle progenitor cells (SMPC) in the bloodstream and promoting atherosclerotic lesions within the vasculature. Approach and Results— SMPC isolated from wild-type and IFN receptor knockout animals were cultured in medium±IFN-I. In vivo, we used electroporation to generate stable IFN-I expression for as long as 4 months. The number of SMPC was determined in mice that expressed IFN-I and in control mice and sections from the bifurcation of the abdominal aorta were analyzed 3 months after electroporation of an IFN-I expression plasmid or a control plasmid. Adding IFN-I to the media increased the number of cultured wild-type SMPC and increased mRNA for SM22, but had no effect on SMPC isolated from IFN receptor knockout mice. Our in vivo results demonstrated a positive relationship between the preatherosclerotic-like lesions and endothelial damage. Although, there were no significant differences in smooth muscle cell density or thickness of the medial layer between groups, the IFN-I–expressing mice had a significant increase in preatherosclerotic-like lesions and immature smooth muscle cells, cells that expressed CD34 and smooth muscle &agr;-actin; but lacked smooth muscle myosin heavy chain. Conclusions— IFN-I seems to enhance SMPC number in vitro. In vivo IFN-I expression may maintain SMPC in an immature state. These immature smooth muscle cells could give rise to macrophages and eventually foam cells.
Cross-lingual Semantic Parsing

We introduce the task of cross-lingual semantic parsing: mapping content provided in a source language into a meaning representation based on a target language. We present: (1) a meaning representation designed to allow systems to target varying levels of structural complexity (shallow to deep analysis), (2) an evaluation metric to measure the similarity between system output and reference meaning representations, (3) an end-to-end model with a novel copy mechanism that supports intrasentential coreference, and (4) an evaluation dataset where experiments show our model outperforms strong baselines by at least 1.18 F1 score.
The Effect of Chlorhexidine Varnish on Root Caries: A Systematic Review

Objective: The aim of this study was to systematically review the present literature on the effect of chlorhexidine varnish (CHX-V) on root caries. Materials and Methods: The MEDLINE-PubMed, the Cochrane-CENTRAL and EMBASE databases were searched through December 2010 to identify any appropriate studies. Root caries incidence and root caries activity were selected as outcome variables. Results: An independent screening of the unique titles and abstracts of 24 MEDLINE-PubMed, 14 Cochrane-CENTRAL and 18 EMBASE papers resulted in 6 publications that met the eligibility criteria. Data extraction provided no conclusive evidence that the application of CHX-V is effective in patients when regular professional oral prophylaxis is performed. If effective, the 40% CHX-V was found to provide a benefit over a control or fluoride varnish. CHX-V at lower concentrations (1 and 10%) may provide protection against root caries in high-risk patients (such as geriatric and xerostomia patients) in the absence of regular professional oral prophylaxis. Conclusion: Within the limitations of this review, it may be concluded that in the absence of regular professional tooth cleaning and oral hygiene instructions, CHX-V may provide a beneficial effect in patients in need of special care. The strength of this recommendation is graded as ‘weak’.
Endoscopic Duodenal Mucosal Resurfacing for the Treatment of Type 2 Diabetes

Type 2 diabetes is a pandemic disease with an incidence that has risen steadily over recent decades. Experimental evidence in animals has demonstrated that intestinal bypass surgery of the upper small intestine, particularly the duodenum, has an important role in glucose homoeostasis. Furthermore, Roux-en-Y bypass performed as bariatric surgery has shown to correct hyperglycaemia from the first postoperative days in obese diabetic patients. Therefore, on the basis of these considerations, duodenal mucosal resurfacing was studied in type 2 diabetes patients as a minimally invasive procedure that could offer an alternative treatment for these patients. Further studies, and particularly large controlled trials, are needed to determine the place of this procedure in the treatment of type 2 diabetes as well as other metabolic diseases such as non-alcoholic fatty liver disease/non-alcoholic steatohepatitis.
