The role of Plasmodium falciparum var genes in malaria in pregnancy
No full textSequestration of Plasmodium falciparum-infected erythrocytes in the placenta is responsible for many of the harmful effects of malaria during pregnancy. Sequestration occurs as a result of parasite adhesion molecules expressed on the surface of infected erythrocytes binding to host receptors in the placenta such as chondroitin sulphate A (CSA). Identification of the parasite ligand(s) responsible for placental adhesion could lead to the development of a vaccine to induce antibodies to prevent placental sequestration. Such a vaccine would reduce the maternal anaemia and infant deaths that are associated with malaria in pregnancy. Current research indicates that the parasite ligands mediating placental adhesion may be members of the P. falciparum variant surface antigen family PfEMP1, encoded by var genes. Two relatively well-conserved subfamilies of var genes have been implicated in placental adhesion, however, their role remains controversial. This review examines the evidence for and against the involvement of var genes in placental adhesion, and considers whether the most appropriate vaccine candidates have yet been identified
Texting "boosts" felt security
No full textAttachment security can be induced in laboratory settings (e.g., Rowe & Carnelley, 2003) and the beneficial effects of repeated security priming can last for a number ofdays (e.g., Carnelley & Rowe, 2007). The priming process, however, can be costly in terms of time. We explored the effectiveness of security priming via text message.Participants completed a visualisation task (a secure attachment experience or neutral experience) in the laboratory. On three consecutive days following the laboratory task, participants received (secure or neutral) text message visualisation tasks. Participants inthe secure condition reported significantly higher felt security than those in the neutral condition, immediately after the laboratory prime, after the last text message prime and one day after the last text prime. These findings suggest that security priming via text messages is an innovative methodological advancement that effectively induces felt security, representing a potential direction forward for security priming research
Repeated priming of attachment security influences immediate and later views of self and relationships
No full textResearch shows that priming attachment security results in positive relationship expectations and affect (Rowe & Carnelley, 2003). We examined whether repetitive priming of attachment security (e.g., experimentally activating cognitive representations of attachment security) would have more lasting effects on relationship- and self-views. Participants provided baseline measures at Time 1. On 3 occasions (across 3 days), we primed participants with attachment security or a neutral prime (Times 2–4). Two days later (Time 5), participants completed trait-level measures not preceded by a prime. As expected, those repeatedly primed with attachment security reported more positive relationship expectations, more positive self-views, and less attachment anxiety at Time 5 than at Time 1; those primed with neutral primes showed no change with time. These priming effects last longer than those typically found

Rynkatorpa Rowe and Pawson 1967
No full textGenus <i>Rynkatorpa</i> Rowe and Pawson, 1967 <p> <b>Diagnosis</b>: Anchor plates more or less irregular in outline, tending to be rectangular, with small number of perforations (25–50), of which two near center line are usually conspicuously larger than the rest; perforations with smooth to spinous margins. One to three Polian vesicles. (After Rowe and Pawson, 1967).</p> <p> <b>Type Species</b>: <i>Rynkatorpa hickmani</i> Rowe and Pawson, 1967</p> <p> <b>Remarks:</b> Rowe and Pawson (1967) listed eight Indo­Pacific species in this genus. Since 1967, three further Indo­Pacific species have been described: <i>R. pawsoni</i> (Martin, 1969a, 1969b), <i>R. gibbsi</i> (Rowe, 1977), and <i>R. coriolisi</i> (Smirnov, 1997). Of the 11 species now known in the genus, four, <i>hickmani</i> Rowe & Pawson, <i>bisperforatus</i> (Clark), <i>gibbsi</i> Rowe, and <i>uncinata</i> (Hutton) are essentially shallow­water forms, known from less than 100 meters depth. The other seven species, <i>bicornis</i> (Sluiter), <i>sluiteri</i> (Fisher), <i>timida</i> (Koehler & Vaney), <i>challengeri</i> (Théel), <i>coriolisi</i> Smirnov, <i>pawsoni</i> Martin, and <i>duodactyla</i> (Clark) are bathyal forms, ranging in depth from 252 to 1,920 meters. It is indeed surprising to find this genus in the Atlantic. Its nearest congeneric neighbors are <i>R. pawsoni</i> and <i>R. duodactyla</i> (Clark); both occur off the west coast of North America, and both differ from <i>R. felderi</i> new species in possessing just one pair of terminal tentacle digits.</p>Published as part of <i>Pawson, David L. & Vance, Doris J., 2005, Rynkatorpa felderi, new species, from a bathyal hydrocarbon seep in the northern Gulf of Mexico (Echinodermata: Holothuroidea: Apodida), pp. 15-20 in Zootaxa 1050</i> on page 16, DOI: <a href="http://zenodo.org/record/169978">10.5281/zenodo.169978</a>
Erythrocyte complement receptor 1 (CR1) expression level is not associated with polymorphisms in the promoter or 3' untranslated regions of the CR1 gene
No full textComplement receptor 1 (CR1) expression level on erythrocytes is genetically determined and is associated with high (H) and low (L) expression alleles identified by a HindIII restriction fragment-length polymorphism (RFLP) in intron 27 of the CR1 gene. The L allele confers protection against severe malaria in Papua New Guinea, probably because erythrocytes with low CR1 expression, are less able to form pathogenic rosettes with Plasmodium falciparum-infected erythrocytes. Despite the biological importance of erythrocyte CR1, the genetic mutation controlling CR1 expression level remains unknown. We investigated the possibility that mutations in the upstream or 3' untranslated regions of the CR1 gene could control erythrocyte CR1 level. We identified several novel polymorphisms; however, the mutations did not segregate with erythrocyte CR1 expression level or the H and L alleles. Therefore, high and low erythrocyte CR1 levels cannot be explained by polymorphisms in transcriptional control elements in the upstream or 3' untranslated regions of the CR1 gene

CR1 Knops blood group alleles are not associated with severe malaria in the Gambia
No full textThe Knops blood group antigen erythrocyte polymorphisms have been associated with reduced falciparum malaria-based in vitro rosette formation (putative malaria virulence factor). Having previously identified single-nucleotide polymorphisms (SNPs) in the human complement receptor 1 (CR1/CD35) gene underlying the Knops antithetical antigens Sl1/Sl2 and McC(a)/McC(b), we have now performed genotype comparisons to test associations between these two molecular variants and severe malaria in West African children living in the Gambia. While SNPs associated with Sl:2 and McC(b+) were equally distributed among malaria-infected children with severe malaria and control children not infected with malaria parasites, high allele frequencies for Sl 2 (0.800, 1,365/1,706) and McC(b) (0.385, 658/1706) were observed. Further, when compared to the Sl 1/McC(a) allele observed in all populations, the African Sl 2/McC(b) allele appears to have evolved as a result of positive selection (modified Nei-Gojobori test Ka-Ks/s.e.=1.77, P-valu
