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...

IPv4-IPv6 transition rolls out numerous challenges to the world of Internet as the Internet is drifting from IPv4 to IPv6. IETF recommends few transition techniques which includes dual stack and translation and tunneling. By means of tunneling the IPv6 packets over IPv4 UDP, Teredo maintains IPv4/IPv6 dual stack node in isolated IPv4 networks behindhand network address translation (NAT). Howeve...

Spikelets, small spikelike membrane potential deflections, are prominent in the activity of hippocampal pyramidal neurons in vivo. The origin of spikelets is still a source of much controversy. Somatically recorded spikelets have been postulated to originate from dendritic spikes, ectopic spikes, or spikes in an electrically coupled neuron. To differentiate between the different proposed mechan...

The need for a fire-induced flashover probability index (FIFPI) for Eskom’s transmission lines (South Africa) became evident soon after the installation the Advanced Fire Information System (AFIS) in 2004. Thousands of wildfires were detected by satellites close to transmission lines, but only a small percentage (4%) of these fires caused a flashover. Historical flashover data was compared to s...

The objective of this paper is to develop neutrosophic quadruple algebraic hyperstructures. Specifically, we develop neutrosophic quadruple semihypergroups, neutrosophic quadruple canonical hypergroups and neutrosophic quadruple hyperrings and we present elementary properties which characterize them. 2010 AMS Classification: 03B60, 20A05, 20N20, 97H40

BACKGROUND We assessed whether quadruple or triple-class therapy for the initial treatment of HIV-1 infection provides a virological benefit over standard triple therapy in patients with very high plasma viraemia. The assessment was made based on a national observational HIV cohort in the Netherlands. METHODS Inclusion criteria were age ≥18 years, treatment-naive, plasma viral load (pVL) ≥500...

BACKGROUND AND AIMS Quadruple therapy is recommended as second-line treatment for Helicobacter pylori eradication failure. However, high cost, multiple side effects, and low adherence rates are major drawbacks to its routine use. Our aim was to compare the efficacy and safety of sequential versus quadruple regimens as second line treatment for persistent Helicobacter pylori infection. METHODS...

A Steiner quadruple system of order v is a set X of cardinality v, and a set Q, of 4-subsets of X, called blocks, with the property that every 3-subset of X is contained in a unique block. A Steiner quadruple system is resolvable if Q can be partitioned into parallel classes (partitions of X). A necessary condition for the existence of a resolvable Steiner quadruple system is that v = 4 or 8 (m...

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...
