Background Although it has been shown to be superior to simple antithrombotic drug therapy, most patients are unable to receive timely percutaneous coronary intervention (PCI) and are treated with conventional triple antithrombotic therapy (aspirin, clopidogrel, low-molecular-weight heparin). Here, we evaluate the efficacy and safety of adding low-dose tirofiban to this regimen. Methods A tot...

INTRODUCTION This study aimed to compare the efficacy and safety of quadruple therapy containing doxycycline and routine quadruple therapy for Helicobacter (H.) pylori rescue eradication in patients who had failed the one-week triple therapy. METHODS Patients who failed the first-line eradication therapy were allocated into two groups. Group A patients (n = 43) were administered esomeprazole ...

In this project we explore the capability and flexibility of FPGA solutions in a sense to accelerate scientific computing applications which require very high precision arithmetic, based on IEEE 754 standard 128-bit floating-point number representations. Field Programmable Gate Arrays (FPGA) is increasingly being used to design high end computationally intense microprocessors capable of handlin...

A blocking quadruple (BQ) is a quadruple of vertices of a graph such that any two vertices of the quadruple either miss (have no neighbours on) some path connecting the remaining two vertices of the quadruple, or are connected by some path missed by the remaining two vertices. This is akin to the notion of asteroidal triple used in the classical characterization of interval graphs by Lekkerkerk...

The fungal pathogen Candida albicans causes lethal systemic infections in humans. To better define how pathogens resist oxidative attack by the immune system, we examined a family of four Flavodoxin-Like Proteins (FLPs) in C. albicans. In agreement with previous studies showing that FLPs in bacteria and plants act as NAD(P)H quinone oxidoreductases, a C. albicans quadruple mutant lacking all fo...

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 non-complicated appendicitis. methods: t...

Quadruple tank process is a Multi-Input-Multi-Output process exhibiting both minimum phase and non-minimum phase behaviour. In this research, an attempt has been made to mathematically model and design a fuzzy controllerr for the non-minimum phase of Quadruple Tank Process. Both servo and regulatory responses are obtained for the proposed controller.

Let N = Ln(q), n ≥ 2, q a prime power, be a projective linear simple group. We classify all Steiner quadruple systems admitting a group G with N ≤ G ≤ Aut(N). In particular, we show that G cannot act as a group of automorphisms on any Steiner quadruple system for n > 2.

Helicobacter pylori (H. Pylori) infection is currently recognized as the major cause of chronic active gastritis, peptic ulcer disease and mucosa associated lymphoid tissue (MALT) lymphoma and carcinoma of the stomach. Eradication of the infection will prevent the recurrence of the majority of such diseases. Different combined treatments have been tried in Iran for eradication of H. Pylori, but...

BACKGROUND Traditional standard triple therapy for Helicobacter pylori (H. pylori) infection (proton pump inhibitor-clarithromycin-amoxicillin) can easily be converted to non-bismuth quadruple (concomitant) therapy by the addition of a nitroimidazole twice daily. AIM To critically review evidence on the role of non-bismuth quadruple therapy (proton pump inhibitor-clarithromycin-amoxicillin-ni...
