Abstract

We consider the efficient numerical solution of the three-dimensional wave equation with Neumann boundary conditions via time-domain boundary integral equations. A space-time Galerkin method with $C^\infty$-smooth, compactly supported basis functions in time and piecewise polynomial basis functions in space is employed. We discuss the structure of the system matrix and its efficient parallel assembly. Different preconditioning strategies for the solution of the arising systems with block Hessenberg matrices are proposed and investigated numerically. Furthermore, a C++ implementation parallelized by OpenMP and MPI in shared and distributed memory, respectively, is presented. The code is part of the boundary element library BEM4I. Results of numerical experiments including convergence and scalability tests up to a thousand cores on a cluster are provided. The presented implementation shows good parallel scalability of the system matrix assembly. Moreover, the proposed algebraic preconditioner in combination with the FGMRES solver leads to a significant reduction of the computational time., Comment: 24 pages

Abstract

OBJECTIVES To assess the antihypertensive and antiproteinuric efficacy and safety of the angiotensin II type 1 receptor blocker telmisartan in patients with hypertension and chronic kidney disease. METHODS A multicenter, prospective trial was performed in adults with hypertension [systolic blood pressure (SBP)/diastolic blood pressure (DBP) >130/85 mmHg), chronic renal insufficiency (serum creatinine 1 g/24 h). In addition to existing antihypertensive therapy, the nature and doses of which remained unchanged throughout the study, patients received once-daily telmisartan 40 mg for the first 3 months followed by forced titration to telmisartan 80 mg for the subsequent 3 months to achieve a target SBP/DBP of

Abstract

ADPKD is the most common hereditary renal disease. IGAN is a mesangial proliferative glomerulonephritis characterized by diffuse mesangial deposition of immunoglobulin A. ET-1 has been suggested to be a major disease-promoting factor in renal diseases. The vasoconstrictor effect of ET-1 is mediated by the ET-A receptor. We have investigated the influence of C/T polymorphism in exon 8 of the EDNRA gene. A total number of 193 patients (87 males, 106 females) with ADPKD entered into this study. Patients were divided into three groups: 1. 47 pts with ESRD later than in 63 years (slow progressors), 2. 49 pts with ESRD before 45 (rapid progressors) and 3. 97 pts with ESRD between 45-63 years. Moreover, we examined a group of 153 pts with histologically proven IGAN (116 males, 37 females). Pts were divided into two groups: 1. 79 pts with ERSD during 5 years of the study (IGAN rapid progressors) and 2. 74 patients with normal renal function (IGAN slow progressors). As a control group we used 100 genetically unrelated healthy subjects. The distribution of C/T polymorphism did not significantly differ between rapid and slow progressors of ADPKD and IGAN. The comparison of ESRD ages showed that CC females with ADPKD failed significantly later than CT heterozygotes: CC (57.4 +/- 8.1 years), CT (53.0 +/- 9.1 years) and TT (54.5 +/- 6.4years) (t-test, P = 0.018). To conclude, the CC genotype could be protective in ADPKD females. This genotype was described to be associated with lower pulse pressure.

26. Vorbeugender Hochwasserschutz durch Wasserrückhalt in der Fläche. Untersucht am Beispiel des Einzugsgebietes der Mulde in Sachsen

Author

Abstract

Der im Falle hochwasserverursachender Niederschläge vorhandene ungesättigte Bodenraum stellt ein wichtiges Potenzial für den vorbeugenden Hochwasserschutz dar. Die gezielte Nutzung dieses Speicherraumes durch infiltrationsfördernde Maßnahmen kann helfen, einen Beitrag zur Hochwasserminderung zu leisten. Für das Einzugsgebiet der Mulde in Sachsen wurde über eine umfangreiche Datenanalyse und grundlegende bodenphysikalische Untersuchungen das durch Maßnahmen in der Land- und Siedlungswasserwirtschaft nutzbare Potenzial nachgewiesen. Die erarbeitete Methodik ist auf andere Einzugsgebiete in Deutschland übertragbar. Sie kann dazu dienen, potentielle Hochwasserminderungsgebiete auszuweisen, in denen bodenbezogene wasserspeichernde Maßnahmen vorrangig empfohlen und gegebenenfalls gefördert werden sollten.

Abstract

Acne vulgaris is a disorder of the skin characterized by changes in blackheads, papules, pustules, and nodules that often occur on the face, shoulders, and back. Propionibacterium acnes is the main habitat that contributes to acne. One of the plants that have an anti-bacterial effect is takokak fruit. This study aims to study the presence or absence of anti-bacterial effects of takokak fruit extract on the growth of Propionibacterium acne bacteria. The test method used is the Diplo disk diffusion method. The fruit was extracted by maceration method using ethanol as a solvent and then diluted using 96% ethanol at a concentration of 25%, 50%, 75%, 100% while the positive control used a clindamycin suspension and negative control of distilled water. The results showed that takokak fruit extract had an antibacterial effect on Propionibacterium acnes with an average diameter inhibition zone of 16.75 mm; 18.3 mm; 18.85 mm; 21.92 mm. Positive control (clindamycin) 37,45; negative control (distilled water) has no value to prevent bacteria.

Abstract

Background: Plasma levels of some pro-inflammatory cytokines and soluble adhesion molecules have been suggested to be useful parameters to assess the activity of antineutrophil cytoplasmic antibody (ANCA)-positive vasculitis and lupus nephritis. We hypothesized that the renal activity of these diseases is better reflected by the urinary excretion and fractional excretion of these molecules. [ABSTRACT FROM PUBLISHER]
