We report the case of a male patient with community-acquired quadruple-valve endocarditis on presumed normal native valves. This patient had originally presented elsewhere with generalized edema and malaise and had been diagnosed with suspicious endocarditis and renal dysfunction, for which he unfortunately received incomplete treatment. Transthoracic and transesophageal echocardiographic exami...

*Correspondence: [email protected] School of Science, Sichuan University of Science and Engineering, Zigong, Sichuan 643000, China Abstract We prove quadruple fixed point theorems in partially ordered metric spaces with mixed g-monotone property. Also, we state some examples to show that our results are real generalization of known ones in quadruple fixed point theory. MSC: 46T99; 54H25; 47H10;...

In an Apollonian circle packing, the curvatures a, b, c, d of any four mutually tangent circles satisfy Descartes’ equation, 2(a + b + c + d) = (a+ b+ c+ d). For an equilateral triangle and a point P , if a, b, c, d denote the squares of the lengths of the sides of the triangle and the distances from P to the vertices of the triangle, then a, b, c, d, satisfy 3(a+ b+ c+d) = (a+ b+ c+d). Define ...

Background: Acute appendicitis is one of the most common acute surgery events. Its main treatment is surgery. However medical management before and after the surgery has an important impact on the treatment. Objective: The aim of study was evaluating the outcomes of single dose and quadruple doses of prophylactic antibiotic therapy in patients with acute ...

Our main result is an existence and uniqueness theorem for Steiner triple systems which associates to every such system a binary code | called the \carrier" | which depends only on the order of the system and its 2-rank. When the Steiner triple system is of 2-rank less than the number of points of the system, the carrier organizes all the information necessary to construct directly all systems ...

Purpose To compare the effectiveness of quadruple-drug therapy consisting of cotrimoxazole (trimethopin and sulfamethoxazole), clindamycin antibiotics, and oral corticosteroid versus triple therapy consisting of pyrimetamine, sulphadiazine, and oral corticosteroid in the resolution of toxoplasmic chorioretinitis. Methods This was a double-blind randomized controlled trial with repeated measur...

Although triple (omeprazole, amoxicillin, and metronidazole) and quadruple (omeprazole, tetracycline, metronidazole, and bismuth subcitrate) therapeutic regimens for H. pylori eradication has been studied much in the general population, there is a lack of data in renal transplanted patients. So, this study aimed at comparing regimens in these patients who were considered being immunocompromised...

We study a general elliptical potential of the form ψ(x + y/q) (0 < q ≤ 1) plus an additional shear (with an arbitrary direction) as models for the observed quadruple lenses. It is shown that a minimum additional shear is needed even just to reproduce the observed positions alone. We also obtain the dependence of the axial ratio, q, on the orientation of the major axis of potential. A general r...

The purpose of the current study was to propose a Korean-specific parameter set for calculating the risk of Down syndrome in the second trimester of pregnancy and to determine the screening performances of triple and quadruple tests in Korean women. Using the data on triple or quadruple screening from three hospitals in Korea during 7 yr, we re-converted the concentrations of four serum markers...

The purpose of this study was to compare triple (T) and quadruple (Q) toe-loop figure skating jumps and quantify basic characteristics of these jumps to provide information to coaches that will assist them in teaching quadruple toe-loops to elite figure skaters. High-speed video was taken during men's practice and competition sessions at the 2002 Salt Lake City Winter Olympics; three-dimensiona...
