The SALMFamides S1 and S2 are two structurally related neuropeptides that are present in starfish, and which share the C-terminal amino acid sequence SXLXFamide, where X is variable. To establish the distribution of S1 and S2 in starfish, we have raised antisera that recognise specifically the C-terminal pentapeptide sequence of either S1 or S2. Here we describe the production and characterisat...

In every dense poset P every maximal antichain S may be partitioned into disjoint subsets S1 and S2 , such that the union of the upset of S1 with the downset of S2 yields the entire poset: U(S1) [ D(S2) = P . To nd a similar splitting of maximal antichains in posets is NP{hard in general.

AIM To evaluate the association between virulence factor status and antibiotic resistance in Helicobacter pylori (H. pylori)-infected patients in Ireland. METHODS DNA was extracted from antral and corpus biopsies obtained from 165 H. pylori-infected patients. Genotyping for clarithromycin and fluoroquinolone-mediating mutations was performed using the Genotype HelicoDR assay. cagA and vacA ge...

This paper considers a constrained version of longest common subsequence problem for two strings. Given strings S1, S2 and P , the constrained longest common subsequence problem for S1 and S2 with respect to P is to find a longest common subsequence lcs of S1 and S2 such that P is a subsequence of this lcs. An O(rn 2m2) time algorithm based upon the dynamic programming technique is proposed for...

The images for Figures 1 and 2 are incorrectly switched. The image that appears as Figure 1 should be Figure 2, and the image that appears as Figure 2 should be Figure 1. The figure legends appear in the correct order. In the section entitled “Validation of RNA-Seq”, S2 Fig should be referenced instead of S1 Fig. Additionally, the files linked to S1 Fig and the file linked to S2 Fig are incorre...

The coronavirus spike protein (S) plays a key role in the early steps of viral infection, with the S1 domain responsible for receptor binding and the S2 domain mediating membrane fusion. In some cases, the S protein is proteolytically cleaved at the S1-S2 boundary. In the case of the severe acute respiratory syndrome coronavirus (SARS-CoV), it has been shown that virus entry requires the endoso...

A language in which we can express arithmetic and which contains its own satisfaction predicate (in the style of Kripke’s theory of truth) can be formulated using just two nonlogical primitives: ′ (the successor function) and Sat (a satisfaction predicate). Let L be a language with vocabulary: , ( ) ∃ ¬ ∨ = ′ Sat plus the variables x0, x1, x2, . . .. A term is a variable followed by zero or mor...
