We construct traveling wave solutions with vortex helix structures for the Schrödinger map equation ∂m ∂t = m× (∆m−m3~e3) on R × R, of the form m(s1, s2, s3 − δ| log | t) with traveling velocity δ| log | along the direction of s3 axis. We use a perturbation approach which gives a complete characterization of the asymptotic behavior of the solutions.

Bordetella pertussis is a gram negative bacterium that causes respiratory tract infection in human (whooping cough). Pertussis toxin (PT) is the main component of current acellular pertussis vaccine and the S1 (subunit1) is the main immunogenic part of it. Thus, S1 has been the target of many studies as a potent candidate of acellular vaccine against Bordetella pertussis, lacking the side effec...

conclusions the most predominant vaca genotypes in our areas were s1/m2 and s1/m1, which regard as the genotypes with more virulence intensity. the h. pylori vacas1a, caga genotypes have a significant relationship with the presence of pud and gc in iranian patients with dyspepsia. results in this study, vaca genotypes s1/m2, s1/m1, s2/m2 and s2/m1 were determined in 43.4%, 19.3%, 13.2% and 6% o...

Sensory maps for pain can be modified by deafferentation or injury, and such plasticity has been attributed mainly to changes in the convergence of projections in "bottom-up" mechanisms. We addressed the possible contribution of "top-down" mechanisms by investigating the functional significance of corticofugal influences from the primary somatosensory cortex (S1) to the ventroposterolateral tha...

The single-strand-specific S1 nuclease from Aspergillus oryzae is an archetypal enzyme of the S1-P1 family of nucleases with a widespread use for biochemical analyses of nucleic acids. We present the first X-ray structure of this nuclease along with a thorough analysis of the reaction and inhibition mechanisms and of its properties responsible for identification and binding of ligands. Seven st...

The high mutation rates of the chicken coronavirus (IBV) cause economic threats to poultry industry. However, most dangerous situation is likelihood changing its sequences into human (COVID-19-like virus). Therefore, in present study we aimed investigate possibility genetic IBV COVID-19. Thus, Spike (S1) Glycoprotein genes both and COVID-19 were aligned, analyzed calculated predict possible cha...

BACKGROUND The cytotoxin associated gene A (cagA), and the vacuolating cytotoxin gene A (vacA) of Helicobacter pylori have been associated to phenotypic characteristics of virulence. The objectives of this study were to detect the presence of cagA and to characterize the allelic variants of vacA in 63 strains of H. pylori isolated from colonized individuals with different clinical outcomes. M...

Ribosomal protein S1 is known to play an important role in translational initiation, being directly involved in recognition and binding of mRNAs by 30S ribosomal particles. Using a specially developed procedure based on efficient crosslinking of S1 to mRNA induced by UV irradiation, we have identified S1 binding sites on several phage RNAs in preinitiation complexes. Targets for S1 on Q beta an...
