Three distinct molecular surfaces in ephrin-A5 are essential for a functional interaction with EphA3

Eph receptor tyrosine kinases (Ephs) function as molecular relays that interact with cell surface-bound ephrin ligands to direct the position of migrating cells. Structural studies revealed that, through two distinct contact surfaces on opposite sites of each protein, Eph and ephrin binding domains assemble into symmetric, circular heterotetramers. However, Eph signal initiation requires the assembly of higher order oligomers, suggesting additional points of contact. By screening a random library of EphA3 binding-compromised ephrin-A5 mutants, we have now determined ephrin-A5 residues that are essential for the assembly of high affinity EphA3 signaling complexes. In addition to the two interfaces predicted from the crystal structure of the homologous EphB2 center dot ephrin-B2 complex, we identified a cluster of 10 residues on the ephrin-A5 E alpha-helix, the E-F loop, the underlying H beta-strand, as well as the nearby B - C loop, which define a distinct third surface required for oligomerization and activation of EphA3 signaling. Together with a corresponding third surface region identified recently outside of the minimal ephrin binding domain of EphA3, our findings provide experimental evidence for the essential contribution of three distinct protein-interaction interfaces to assemble functional EphA3 signaling complexes.

House building productivity : a study of labour requirements on Scottish house building sites using activity sampling methods

This study is concerned with labour productivity in traditional house building in Scotland. Productivity is a measure of the effective use of resources and provides vital benefits that can be combined in a number of ways. The introduction gives the background to two Scottish house building sites (Blantyre and Greenfield) that were surveyed by the Building Research Establishment (BEE) activity sampling method to provide the data for the study. The study had two main objectives; (1) summary data analysis in average manhours per house between all the houses on the site, and (2) detailed data analysis in average manhours for each house block on the site. The introduction also provides a literature review related to the objectives. The method is outlined in Chapter 2, the sites are discussed in Chapter 3, and Chapter 4 covers the method application on each site and a method development made in the study. The summary data analysis (Chapter 5) compares Blantyre and Greenfield, and two previous BEE surveys in England. The main detailed data analysis consisted of three forms, (Chapters 6, 7 and 8) each applied to a set of operations. The three forms of analysis were variations in average manhours per house for each house block on the site compared with; (1) block construction order, (2) average number of separate visits per house made by operatives to each block to complete an operation, and (3) average number of different operatives per house employed on an operation in each block. Three miscellaneous items of detail data analysis are discussed in Chapter 9. The conclusions to the whole study state that considerable variations in manhours for repeated operations were discovered, that the numbers of visits by operatives to complete operations were large and that the numbers of different operatives employed in some operations were a factor related to productivity. A critique of the activity sampling method suggests that the data produced is reliable in summary form and can give a good context for more detailed data collection. For future work, this could take the form of selected operations, with the context of an activity sampling survey, that wuld be intensively surveyed by other methods.

Drivers of supply chain collaboration among Finnish manufacturers

This paper focuses on data exchange relationships and ways to improve collaboration in the supply chain. Initially, the paper examines the information needs and alternatives in supply chain management. In the second part, the paper identifies different sets of factors that are likely to influence information sharing with suppliers, from the manufacturers’ point of view. Results from a Finnish Manufacturing industry survey show that manufacturers provided substantial information on demand data, production schedules, and inventories to their suppliers. Respondents perceived delivery performance measured by the timeliness, accuracy, and defect rate of deliveries as the primary incentives for supplier collaboration. On the other hand, supplier image and the market in which the supplier operates were found to be less relevant in determining the intensity of collaboration.

Effect of High Pressure on the Electrical Conductivity of TlInX2 (X = Se, Te) Layered Semiconductors

The dc electrical conductivity of TlInX2 (X = Se, Te) single crystals, parallel and perpendicular to the (001) c-axis is studied under high quasi-hydrostatic pressure up to 7.0 GPa, at room temperature. Conductivity measurements parallel to the c-axis are carried out at high pressures and down to liquid nitrogen temperatures. These materials show continuous metallization under pressure. Both compounds have almost the same pressure coefficient of the electrical activation energy parallel to the c-axis, d(ΔE∥)/dP = −2.9 × 10−10 eV/Pa, which results from the narrowing of the band gap under pressure. The results are discussed in the light of the band structure of these compounds.

Associação entre periodontite crônica e marcadores de risco para doença cardiovascular

Pesquisas recentes têm demonstrado que a periodontite pode modificar a concentração sanguínea de uma série de tipos celulares e substâncias bioquímicas, que são considerados fatores de risco para doenças cardiovasculares. Este trabalho tem como objetivo avaliar a associação entre a periodontite crônica e marcadores de risco para doença cardiovascular. No Estudo I foram examinados 100 pacientes aparentemente saudáveis sistemicamente, sendo 66 portadores de periodontite crônica e 34 pacientes controle, sem doença periodontal. Exames periodontais e exames sanguíneos foram realizados, e obtidas as espessuras das camadas íntima-média (IMT) da artéria carótida. No Estudo II, 66 pacientes participantes do Estudo I, diagnosticados com periodontite crônica, foram aleatoriamente submetidos a tratamento periodontal imediato (Grupo Teste, n=33) ou tratamento periodontal retardado (Grupo Controle, n=33). Os dados colhidos no Estudo I foram registrados como pré-tratamento (T0). Novos exames clínicos periodontais e laboratoriais foram realizados no período de 2 meses (T2) e 6 meses (T6) após os exames iniciais (Grupo Controle) ou conclusão do tratamento periodontal (Grupo Teste). Os dados colhidos foram analisados através de testes estatísticos. Os resultados mostraram que pacientes com periodontite crônica quando comparados ao grupo controle, apresentaram valores médios significativamente mais elevados na contagem total de hemácias (p<0,001), hemoglobina (p<0,001), hematócrito (p<0,001), contagem de plaquetas (p=0,019), velocidade de hemossedimentação (p<0,001), proteína C-reativa (p<0,001). Os níveis de HDL-colesterol foram significativamente mais baixos nos pacientes com periodontite crônica quando comparados ao grupo controle (p<0,001). As camadas íntima-média da parede da artéria carótida esquerda foram significativamente mais espessas nos pacientes com periodontite crônica quando comparados ao grupo controle (p=0,049). Os indíviduos com periodontite crônica também apresentaram 3,26 vezes mais chances de possuir Síndrome Metabólica do que aqueles indivíduos que não possuem doença peridontal (IC 95%: 1,8-5,9). No Estudo II, quando comparados os valores médios dos dados hematológicos após tratamento, no grupo teste, foi possível observar melhora estatisticamente significativa, entre T0/T2, dos valores de VHS e triglicerídeos (p=0,002; p=0,004; respectivamente). Redução nos valores médios da contagem total de leucócitos, VHS, CRP, transaminase glutâmico pirúvica, colesterol total e triglicerídeos, entre T0/T6, foi verificada no grupo teste pós-tratamento (p=0,028; p<0,001; p<0,001; p=0,010; p<0,001; p=0,015, respectivamente). Os resultados indicaram que a periodontite crônica severa está associada com níveis elevados de marcadores da inflamação e trombogênese, além de alterações no perfil lipídico em indivíduos sistemicamente saudáveis, podendo atuar como possível fator de risco para as doenças cardiovasculares. O tratamento periodontal não-cirúrgico mostrou-se eficaz na redução dos níveis dos marcadores sistêmicos da inflamação e na melhora do perfil lipídico em indivíduos com doença periodontal severa, consequentemente, reduzindo o risco de doenças cardiovasculares.
