Quasi-multipliers of Hilbert and Banach C*-bimodules
No full textQuasi-multipliers for a Hilbert C*-bimodule V were introduced by L. G. Brown, J. A. Mingo, and N.-T. Shen as a certain subset of the Banach bidual module V**. We give another (equivalent) definition of quasi-multipliers for Hilbert C*-bimodules using the centralizer approach and then show that quasi-multipliers are, in fact, universal (maximal) objects of a certain category. We also introduce quasi-multipliers for bimodules in Kasparov's sense and even for Banach bimodules over C*-algebras, provided these C*-algebras act non-degenerately. A topological picture of quasi-multipliers via the quasi-strict topology is given. Finally, we describe quasi-multipliers in two main situations: for the standard Hilbert bimodule and for bimodules of sections of Hilbert C*-bimodule bundles over locally compact spaces
Role of Pavlov-like Strategy on Emergence of Cooperation in Demographic Donor-Recipient Game
No full textProceedings of the 16th Czech-Japan Seminar on Data Analysis and Decision Making under Uncertainty に掲載された論文に加筆修正したものWe deal with Pavlov-like strategy as well as Tit for Tat-like strategy in Demographic Donor-Recipient (DR) game. We study the role of Pavlov-like strategy on the emergence of cooperation by Agent-Based Simulation. We extend Tit for Tat (TFT) and Pavlov (Pav) up to three states from two and call them TFT-like and Pavlov-like strategy, respectively. Unlike TFT-like, Pav-like has the following feature: Pav-like changes to using C from using D or remains in using D if he is using D and experiences opponents' D's or C's, respectively. Thus we expect that some Pavlov-like strategies in the population may soften the tendency toward defection of the whole population and also the tendency toward full cooperation of the whole population. Although sole Pavlov-like strategy is not so e ective to promote the cooperation, we found case where the cooperation emerges more frequently with both TFT-like and Pavlov-like strategy than with sole TFT-like (or Pav-like) strategy.16th Czech-Japan Seminar on Data Analysis and Decision Making under UncertaintyCzechSeptember 18-22, 2013conference pape
FibroTest, transient elastography method, and combined FibroTest and transient elastography method for diagnosis of severe hepatic fibrosis and cirrhosis in adults with chronic hepatitis C
No full textThis is the protocol for a review and there is no abstract. The objectives are as follows: To determine the diagnostic accuracy of FibroTest, transient elastography method, combined FibroTest and transient elastography method, no matter the sequence, using liver biopsy as reference standard, for assessment of severe hepatic fibrosis and cirrhosis in adults with chronic hepatitis C without any co-infections such as hepatitis B, HIV, and alcoholic liver disease. To compare the accuracy of FibroTest, transient elastography method, combined FibroTest and transient elastography method, for assessment of hepatic fibrosis in adults with chronic hepatitis C. To explore heterogeneity analysing the following study factors: different grade of inflammation according to the liver biopsy; different lengths of liver biopsy sample; different number of portal tracts included in a liver biopsy sample; different serum levels of ALT activity. different grade of inflammation according to the liver biopsy; different lengths of liver biopsy sample; different number of portal tracts included in a liver biopsy sample; different serum levels of ALT activity
Going Beyond Counting First Authors in Author Co-citation Analysis
No full textThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Essential phospholipids for people with non-alcoholic fatty liver disease (Protocol)
No full textNon-alcoholic fatty liver disease (NAFLD) covers conditions related to accumulation of fat in the liver if specific causes, such as significant alcohol consumption, long-term use of a steatogenic medication, or monogenic hereditary disorders can be excluded (WGO 2014). Non-alcoholic fatty liver disease features a wide spectrum of histologically conditions, from simple accumulation of fat ('fatty liver' or hepatic steatosis) to non-alcoholic steatohepatitis (NASH), liver fibrosis, and liver cirrhosis with clinical consequences (Brunt 2011; McPherson 2015; Bertot 2016). Simple hepatic steatosis is defined as when the fat, built up in the epithelial cells of the liver, is at least 5% of the liver weight, and the parenchymal cells and liver structure are intact. Non-alcoholic fatty liver (NAFL) is defined as the presence of hepatic steatosis with no evidence of hepatocellular injury in the formof ballooning of the hepatocytes. Non-alcoholic steatohepatitis is defined as the presence of hepatic steatosis and inflammation with hepatocyte injury (ballooning) with or without fibrosis (Brunt 2011). Nonalcoholic fatty liver disease is considered to be a clinical manifestation of the metabolic syndrome, that is the co-occurrence of metabolic risk factors for both type 2 diabetes and cardiovascular disease (abdominal obesity, hyperglycaemia, dyslipidaemia, and hypertension) (Dyson 2014;Mikolasevic 2016; AASLD NAFLD 2018). The prevalence of NAFLD is increasing, but only a small number of affected people develop inflammation, which may be followed by fibrosis and cirrhosis, possibly requiring liver transplantation (Bertot 2016; Younossi 2016). The life expectancy in people with hepatic steatosis is reported to be similar to the life expectancy of the general population (Lazo 2011)
Hippodonta exigua A. Pavlov, Levkov, D. M. Williams & Edlund 2013, sp. nov.
No full textHippodonta exigua A. Pavlov, Levkov, D.M. Williams & Edlund, sp. nov. (Figs 201–212, 225) Type:— MACEDONIA. Lake Prespa, Bay of Stenje, littoral sediment, 28 June 2002, collector Z. Levkov. (Accession No. MKNDC 000142; holotype: slide MKNDC! 000142/1; isotype: slide BM! 101642). Valves strictly lanceolate, with narrow and long protracted and broadly rounded valve ends. Valve length 14.5–19.0 µm, width 4.0– 4.5 µm. Axial area narrow-linear throughout, expanding into a transverse small, irregularly shaped central area. Usually, central area defined by shortening of one central stria, from both valve sides. Terminal area clearly discernible in LM, small, semi-circular in shape. Raphe linear-filiform, with weakly pronounced, small teardrop-shaped central pores. Central pores closely spaced. Terminal pores of raphe discernible in LM, as round-shaped. Striae fine, moderately to strongly radiate at middle, becoming parallel towards valve ends, 14 in 10 µm. Interstriae of equal or higher width than striae, evenly pronounced throughout valve length. In longer valves, interstriae more pronounced than striae. Lineolae composing striae quite densely spaced within a stria and not clearly distinguishable in LM. SEM: Externally, valve face flat (Fig. 225). Terminal area expanding weakly onto valve face. Terminal pores of raphe simple teardrop-shaped and weakly pronounced, slightly advancing into the terminal area. Terminal pores of raphe slightly deflected towards one valve side. Striae uniseriate. Lineolae simple linear, moderately pronounced and short, c. 40 in 10 µm. Rows of lineolae positioned on apical valve mantle also uniseriate. Distribution:— Hippodonta exigua has so far only been observed from Lake Prespa, Macedonia, where it occurs on organic sediment from various depths. Observations:—A specimen depicted in Lange-Bertalot (2001: fig. 79: 6) named as " Hippodonta spec. ", from Lake Baikal, is quite similar to H. exigua with respect to valve outline and appearance of the striae. However, H. exigua has slightly more densely spaced striae (14 in 10 µm compared to 10 striae in 10 µm on the specimen from Lake Baikal) as well as somewhat more broadly protracted valve ends. In addition, and concerning the valve outline, H. exigua is also similar to H. coxiae Lange-Bert. (2001: 221, 222, figs 76: 29–33), but the latter species has shorter protracted, broadly rostrate and broadly rounded valve ends, when compared to the narrow and long protracted valve ends in H. exigua. Furthermore, the terminal area of H. coxiae is more strongly pronounced and the lineolae are clearly discernible in LM.Published as part of Pavlov, Aleksandar, Levkov, Zlatko, Williams, David M. & Edlund, Mark B., 2013, Observations on Hippodonta (Bacillariophyceae) in selected ancient lakes, pp. 1-53 in Phytotaxa 90 (1) on page 19, DOI: 10.11646/phytotaxa.90.1.1, http://zenodo.org/record/507197

Abstract
PURPOSE: To evaluate the role of topical mitomycin C in corneal wound healing (CWH) after photorefractive keratectomy (PRK) in highly myopic eyes.
DESIGN: Prospective, double-masked, randomized clinical trial.
PARTICIPANTS: Seventy-two eyes of 36 patients affected by high (>7 diopters) myopia.
METHODS: In each patient, one eye was randomly assigned to PRK with intraoperative topical 0.02% mitomycin C application, and the fellow eye was treated with a placebo. Postoperatively, mitomycin C-treated eyes received artificial tears (3 times daily, tapered in 3 months), whereas the fellow eye was treated with fluorometholone sodium 2% and artificial tears (3 times daily, tapered in 3 months).
MAIN OUTCOME MEASURES: Uncorrected visual acuity (UCVA) and best-corrected visual acuity (BCVA), contrast sensitivity, manifest refraction, and biomicroscopy. Contrast sensitivity was determined using the Pelli-Robson chart. Corneal confocal microscopy documented CWH.
RESULTS: Mean follow-up was 18 months (range, 12-36). No side effects or toxic effects were documented. At 12-month follow-up examination, UCVAs (logarithm of the minimum angle of resolution) were 0.4+/-0.48 and 0.5+/-0.53 (P = .03) in mitomycin C-treated eyes and corticosteroid-treated eyes, respectively. At 1 year, corneal haze developed in 20% of corticosteroid-treated eyes, versus 0% of mitomycin C-treated eyes. At 12, 24, and 36 months, corneal confocal microscopy showed activated keratocytes and extracellular matrix significantly more evident in untreated eyes (Ps = 0.004, 0.024, and 0.046, respectively).
CONCLUSION: Topical intraoperative application of 0.02% mitomycin C can reduce haze formation in highly myopic eyes undergoing PRK.
