Helicobacter pylori is a gram-negative rod associated with gastroduodenal pathologies, such as gastritis, peptic ulcer, and gastric adenocarcinoma. Although most H. pylori infections are clinically silent, the organism is associated with substantial morbidity and mortality. It is unknown why the bacteria are able to produce severe disease in some hosts and be innocuous in others. Different viru...

The paper presents a part of the results obtained in a complex research project on Romanian Grey Steppe breed, owner of some remarkable qualities such as hardiness, longevity, adaptability, special resistance to ban weather and diseases and included in the genetic fund (G.D. no. 822/2008.) from Romania. Following the researches effectuated, we identified alleles of six loci, codifying the six t...

Genetic and receptor interference data have indicated the presence of one or more cellular receptors for subgroup B, D, and E avian leukosis viruses (ALV) encoded by the s1 allele of the chicken tvb locus. Despite the prediction that these viruses use the same receptor, they exhibit a nonreciprocal receptor interference pattern: ALV-B and ALV-D can interfere with infection by all three viral su...

The self-incompatibility response involves S allele-specific recognition between stigmatic S proteins and incompatible pollen. This response results in pollen inhibition. Defining the amino acid residues within the stigmatic S proteins that participate in S allele-specific inhibition of incompatible pollen is essential for the elucidation of the molecular basis of the self-incompatibility respo...

The vacA s and m genotypes and the presence of cagA and IS605 were determined in Helicobacter pylori strains from patients with mono- and multiple infections. Surprisingly, these genetic markers were not associated with nonulcer dyspepsia or mucosa-associated lymphoid tissue lymphoma. The presence of cagA correlated with the presence of the vacA s1 allele (P < 0.05), whereas the presence of IS6...

Targeting construct, genotyping, colony generation and analysis. We have isolated Nobox genomic clones from a 129S6/SvEv genomic library and generated a targeting construct (Fig. S1A). The Nobox targeting construct was electroporated into AB2.2 ES cells to mutate the wild type Nobox locus by homologous recombination as previously described(S1,S 2). The mutant Nobox allele replaces exons 2-8 wit...

Otani et al. reported the genetic interactions between ikkε and spn-F, using the allele ikkε. This allele was referred to in the Materials and Methods on p. 2349, Fig. 3 on p. 2343 and Table S1. However, they subsequently found that the allele used in the experiments was ikkε (also known as ikkε). This was as a result of misannotation in their laboratory stock list. Both alleles are strong loss...

(1) For all real numbers s1, s3, s4, l such that s1 ≤ s3 and s1 ≤ s4 and 0 ≤ l and l ≤ 1 holds s1 ≤ (1− l) · s3 + l · s4. (2) For all real numbers s1, s3, s4, l such that s3 ≤ s1 and s4 ≤ s1 and 0 ≤ l and l ≤ 1 holds (1− l) · s3 + l · s4 ≤ s1. (3) If n > 0, then mn mod m = 0. (4) If j > 0 and i mod j = 0, then i÷ j = j . (5) If n > 0, then in÷ i = in i . (6) If 0 < n and 1 < r, then 1 < rn. (7)...

Self-incompatibility in almond and Prunus species is an important trait that prevents self-fertilization. Selfincompatibility in almond is controlled gametophytically by the multiallelic S-locus. Present study was done in order to identification and preliminary selection of self compatible progenies resulted from controlled crosses in almond using specific primer SfF/SfR. Some important morphol...
