conclusions we found considerable relationship between s1a/m1a, s1a/m2, s2/m2 and s1c/m1a and some gastric disorders. further studies about the role of h. pylori virulence factors and gastric disorders were recommended. results the frequency of the vaca genotypes, sa1/m1, s1a/m1b, s1a/m2, s1b/m1a, s1b/m1b, s1b/m2, s1c/m1a, s1c/m1b, s1c/m2, s2/m1a, s2/m1b and s2/m2 were 27(6.6%), 8(4.3%), 45(28....

Then, let q(x) = ∑ m∈M (am ·m(x)) be the weighted sum of these monomials, for a set of weights {am}m∈M . We want to choose the weights in order to give q the properties already stated, which is equivalent to finding a non-trivial solution to a certain system of equations. Denote S = {s1, . . . , s|S|} and M = {m1, . . . ,m|M |}. Then, the system of equations we would like to solve is  m1(s1...

BACKGROUND Helicobacter pylori have different virulence factors which are associated with several gastroduodenal diseases; however, this association is variable in different geographical regions. Data of genotypes of Iranian H. pylori isolates are few. OBJECTIVES The aim of the current study was to investigate the cagA/vacA genotypes of Helicobacter pylori isolates and determine the relations...

Several different families of vacuolating toxin (vacA) alleles are present in Helicobacter pylori, and they encode products with differing functional activities. H. pylori strains containing certain types of vacA alleles have been associated with an increased risk for peptic ulcer disease. In this study, we tested serum samples and gastric juice from 19 H. pylori-negative and 39 H. pylori-posit...

Fig.2. Manganese-induced ΔR1 in contralesional M2, S1FL and S2 at 1 day after injection in M1, and corresponding functional connectivity (FC) between contralesional M1 and M2, S1FL and S2 for both control (=C) (n=7) and stroke (=S) (n=5) groups. Enhanced functional and structural connectivity in the contralesional hemisphere after unilateral stroke in rats: A combined resting-state fMRI and MEM...

We study DBI-type effective theory of an unstable D3-brane in the background manifold R×M2 where M2 is an arbitrary two-dimensional manifold. We obtain an exact tubular D2-brane solution of arbitrary cross sectional shape by employing 1/ cosh tachyon potential. When M2 = S2, the solution is embedded in the background geometry R1,3 × S2 of Salam-Sezgin model. This tachyon potential shows a uniqu...

The long-term changes in the main tidal constituents (O1, K1, M2, N2, and S2) along the coasts of China and in adjacent seas are investigated based on 17 tide-gauge records covering the period 1954– 2012. The observed 18.61 year nodal modulations of the diurnal constituents O1 and K1 are in agreement with the equilibrium tidal theory, except in the South China Sea. The observed modulations of t...

In an earlier paper, the authors showed that standard semigroups M1, M2 andM3 play an important role in the classification of weaker versions of alg-universality of semigroup varieties. This paper shows that quasivarieties generated by M2 and M3 are neither relatively alg-universal nor Q-universal, while there do exist finite semigroups S2 and S3 generating the same semigroup variety as M2 and ...
