BACKGROUND The eradication of Helicobacter pylori (H. pylori) can be challenging in certain circumstances. There is no current first-line therapy that is curative in all patients. OBJECTIVE This article summaries the role of emerging novel therapies in the treatment of 
H. pylori. Known as sequential therapy and salvage therapy, these new therapeutic strategies are thought to produce eradicat...

The sequential sound therapy is a treatment for tinnitus with white noise that has some own characteristics. We describe the methodology, as well as their differences and similarities with the Tinnitus Retraining Therapy. The sequential sound therapy has been carried out to seventeen patients assisted during the year 2002. 26 generators of sound were adapted, of them, 22 had incorporated an ear...

We present herein a new and efficient four-component synthesis of isoxazol-5(2H)-ones involving ring closing/Knoevenagel condensation/Michael addition sequential reactions.

childrenwith helicobacter infection need treatment. the aim of treatment is elimination of h.pylori. most patients with this infection are asymptomatic and without peptic disease. treatment and management of these patients are controversy. conventional treatment: the best treatment for h. pylori eradication regimens should have cure rates of at least 80%, be without major side effects, and indu...

   One of the several promising new technologies for computing at nano-scale is quantum-dot cellular automata (QCA). In this paper, new designs for different QCA sequential circuits are presented. Using an efficient QCA D flip-flop (DFF) architecture, a 5-bit counter, a novel single edge generator (SEG) and a divide-by-2 counter are implemented. Also, some types of oscillators, a new edge-t...

BACKGROUND The eradication rate of Helicobacter pylori (H. pylori) with triple therapy which was considered as standard first-line treatment has decreased to 70-85%. The aim of this study is to compare 7-day triple therapy versus 10-day sequential therapy as the first line treatment. METHODS Data of 1240 H. pylori positive patients treated with triple therapy or sequential therapy from Januar...

In this paper a new sequential sampling plan is introduced in which the acceptable quality level (AQL) and the lot tolerance percent defective (LTPD) are a fuzzy number. This plan is well defined, since, if the parameters are crisp, it changes to a classical plan. For such a plan, a particular table of rejection and acceptance is calculated and compared with the classical one. Keywords : St...
