Subject:
hyperbolic periodic point, differentiable map, Lefschetz number, Lefschetz zeta function, quasi-unipotent map, and almost quasi-unipotent map
Language:
English
Description:
Let X be a connected closed manifold and f a self-map on X. We say that f is almost quasi-unipotent if every eigenvalue λ of the map f∗k (the induced map on the k-th homology group of X) which is neither a root of unity, nor a zero, satisfies that the sum of the multiplicities of λ as eigenvalue of all the maps f∗k with k odd is equal to the sum of the multiplicities of λ as eigenvalue of all the maps f∗k with k even. We prove that if f is C 1 having finitely many periodic points all of them hyperbolic, then f is almost quasi-unipotent.

Type:

Subject:
obfuscaton, source code, and malware
Language:
English
Description:
Obfuscation is a process that changes the code, but without any change to semantics. This process can be done on two levels. On the binary code level, where the instructions or control flow are modified, or on the source code level, where we can change only a structure of code to make it harder to read or we can make adjustments to reduce chance of successful reverse engineering.

2216. C*-algebras have a quantitative version of Pełczyński's property (V)

Subject:
matematika, mathematics, Pełczyński's property (V), $C^*$-algebra, Grothendieck property, 13, and 51
Language:
English
Description:
A Banach space $X$ has Pełczyński's property (V) if for every Banach space $Y$ every unconditionally converging operator $T\colon X\to Y$ is weakly compact. H. Pfitzner proved that $C^*$-algebras have Pełczyński's property (V). In the preprint (Krulišová, (2015)) the author explores possible quantifications of the property (V) and shows that $C(K)$ spaces for a compact Hausdorff space $K$ enjoy a quantitative version of the property (V). In this paper we generalize this result by quantifying Pfitzner's theorem. Moreover, we prove that in dual Banach spaces a quantitative version of the property (V) implies a quantitative version of the Grothendieck property., Hana Krulišová., and Obsahuje bibliografii

2217. C-banding, fluorescent staining and NOR location in holokinetic chromosomes of bugs of the Neotropical genus Antiteuchus (Heteroptera: Pentatomidae: Discocephalinae)

Subject:
Heteroptera, Antiteuchus, holokinetic chromosomes, C-banding, NORs, and fluorochromes
Language:
English
Description:
Different cytogenetic techniques including C-banding, base-specific fluorochromes and silver nitrate staining were used to compare the karyotypes of three species of bugs, representatives of the Neotropical genus Antiteuchus, namely A. mixtus, A. sepulcralis and A. macraspis. The species have holokinetic chromosomes which is typical of the Hemiptera, and their diploid chromosome number is 2n = 14 and they have an XX/XY (female/male) sex chromosome system. C-banding revealed telomeric blocks of constitutive heterochromatin in most chromosomes of these three species. In each species, CMA3-positive blocks were observed in the telomeric heterochromatin region of chromosome pair 1. This chromosome pair carried the nucleolar organizer region (NOR), which silver nitrate staining revealed is located in the telomeric heterochromatin. In contrast to the result obtained with CMA3, entire chromosome complement stained homogenously with DAPI, except for the telomeric region of pair 1, which remained unstained.

Description:
Cíl práce: Posoudit vliv jednorázové hemodialýzy a dlouhodobé pravidelné hemodialyzační léčby (1 rok) na hladinu C-reaktivního proteinu (CRP) u pacientů s chronickým renálním selháním. Název a sídlo pracoviště: Oddělení klinické biochemie, FN u sv. Anny v Brně. Materiál a metody: Do sledování bylo zavzato celkem 27 nemocných podstupujících pravidelnou hemodialýzu (bikarbonátová hemodialýza, membrána hemophan). Dialýzy probíhaly po dobu 3–4 hodin 3krát týdně. Plazmatická koncentrace CRP, albuminu a diferenciální rozpočet leukocytů byly stanoveny běžnými rutinními metodami. Krev na vyšetření byla odebrána před hemodialýzou a po hemodialýze na počátku sledování a znovu po 12 měsících pravidelné hemodialyzační léčby. K vyhodnocení byly použity párové přístupy statistické analýzy: dvoucestná analýza rozptylu (ANOVA) u parametricky rozložených dat a Wilcoxonův párový test pro neparametrická data. Výsledky: Průměrná koncentrace CRP byla po jednorázové hemodialýze signifi kantně vyšší, než před hemodialýzou (12,3 ± 2,22 a 9,9 ± 2,12 mg/l, p < 0,01). Po 12 měsících pravidelné hemodialýzy nebyl nalezen signifi kantní rozdíl v hladině CRP ve srovnání s hodnotou na počátku sledování (8,6 ± 2,83 a 9,9 ± 2,12 mg/l, p = 0,191). Závěr: Výsledky podporují hypotézu, že aktivaci mediátorů zánětu (CRP) může ovlivnit jednorázová hemodialyzační procedura, hladina CRP však nezávisí na délce trvání chronické hemodialyzační léčby., Objective: To identify if a single hemodialysis session or long-term (one year) hemodialysis treatment infl uences serum C-reactive protein (CRP) level in patients with chronic renal failure. Settings: Department of Clinical Biochemistry, St. Anna’s Faculty Hospital, Brno, Czech Republic. Methods: A total of 27 patients on maintenance hemodialysis (bicarbonate hemodialysis with hemophan membrane) were included in the study. Their chronic dialysis protocol consisted of 3-4 hours sessions three times a week. Plasma CRP concentration, blood leukocyte differential counts and albumin were determined by routine methods. Blood samples were taken before and after a single hemodialysis sessions at the start of the study, and after 12 months of regular hemodialysis treatment. Two-factor analysis of variance in parametrically ordered data and the Wilcoxon paired test for non-parametrically ordered data were used. Results: The mean CRP level after a 4-hour hemodialysis session was signifi cantly higher than that before hemodialysis (12.3 ± 2.22 and 9.9 ± 2.12 mg/l, p < 0.01). No signifi cant changes in mean CRP levels were found after 12 months of regular hemodialysis treatment in comparison with CRP levels at the start of the study (8.6 ± 2.83 and 9.9 ± 2.12 mg/l, p = 0,191). Conclusion: Our study corroborates the hypothesis that the hemodialysis procedure itself can affect infl ammation markers (CRP), but CRP level does not depend on the length of time of regular hemodialysis treatment., Soška Vladimír, Sobotová D., and Lit.: 23

E. coli, random-amplified-polymorphic-DNA, 3H primer, high-resolution melt, and sequence characterized amplified (region)
Language:

Description:
A single random oligonucleotide 3H primer has been previously applied in random-amplfied-polymorphic-DNA (RAPD)-PCR to distinguish stocked bacteria E. coli within a cocktail mixture also containing Enterococcus faecalis, Bifidobacterium longum and Ruminococcus gnavus. In this study, we demonstrate that a 702 base pair (bp) gene fragment can be amplified as a unique pattern by RAPD-PCR using a 3H primer in human faeces containing E. coli. This unique 702 bp amplicon contained a 687 bp gene fragment identified as the C-terminal region of the glutamate-ammonia-ligase adenyltransferase (glnE) gene of E. coli. By high-resolution melt (HRM) analysis, a mean melt-curve temperature of this 702 bp amplicon was determined to be approximately 88.1 ± 0.22 degrees Celsius (°C). A combination of RAPD with HRM in one single reaction based on this amplicon can achieve semi-quantitative detection of up to 102 CFU/ml of E. coli. To increase the signal intensity of HRM, a primer pair capable of screening E. coli directly from fresh human faeces was re-designed from the 687 bp gene segment, giving a mean peak melt-curve temperature at 88.35 ± 0.11 °C. Finally, single-nucleotide polymorphisms of this 687 bp gene segment were analysed for pathogenic E. coli strains, including UMN026, O83:H1, O104:H4, O157:H7 and O169:H41. We conclude that this 687 bp segment of the glnE gene has a high potential for screening of human faecal E. coli, including pathogenic strains, in contaminated food and water. and Corresponding author: Ko-Tung Chang
