TDR Targets: a chemogenomics resource for neglected diseases

The TDR Targets Database (http://tdrtargets.org) has been designed and developed as an online resource to facilitate the rapid identification and prioritization of molecular targets for drug development, focusing on pathogens responsible for neglected human diseases. The database integrates pathogen specific genomic information with functional data (e.g. expression, phylogeny, essentiality) for genes collected from various sources, including literature curation. This information can be browsed and queried using an extensive web interface with functionalities for combining, saving, exporting and sharing the query results. Target genes can be ranked and prioritized using numerical weights assigned to the criteria used for querying. In this report we describe recent updates to the TDR Targets database, including the addition of new genomes (specifically helminths), and integration of chemical structure, property and bioactivity information for biological ligands, drugs and inhibitors and cheminformatic tools for querying and visualizing these chemical data. These changes greatly facilitate exploration of linkages (both known and predicted) between genes and small molecules, yielding insight into whether particular proteins may be druggable, effectively allowing the navigation of chemical space in a genomics context

Seletividade de Metarhizium anisopliae à Telenomus podisi (Hymenoptera: Scelionidae).

Telenomus podisi e Metarhizium anisopliae são agentes de controle biológico que ocorrem ou podem ser utilizados conjuntamente. Entretanto, estudos de compatibilidade entre parasitoides e fungos entomopatogênicos são escassos. O objetivo deste trabalho foi avaliar a seletividade do fungo M. anisopliae a adultos do parasitoide de ovos T. podisi. Suspensões de M. anisopliae (1,0×109 conídios/ml) foram pulverizadas sobre placas de vidro em Torre de Potter e secas à temperatura ambiente, formando uma película. Como testemunha foi utilizada água destilada estéril + Tween 80 (0,01%). As placas de vidro pulverizadas foram utilizadas na construção de gaiolas de exposição (IOBC) e em seu interior foram liberados adultos de T. podisi com 24 h de idade. As gaiolas foram mantidas em condições controladas de temperatura, umidade e fotoperiodo (25±1º C, 80% UR, 14 h) e os parasitóides foram alimentados com mel. Cartelas contendo ovos de Euschistus heros foram oferecidas às fêmeas de T. podisi 24 h, 48 h, 72 h e 144 h após a pulverização e, sendo posteriormente, acondicionadas em sacos plásticos para avaliar a porcentagem de parasitismo e viabilidade dos parasitoides. Os resultados obtidos indicam que mesmo com as aplicações de M. anisopliae, o parasitismo e a viabilidade foram superiores a 70%, mostrando que o fungo é seletivo aos adultos de T. podisi, sendo classificado como inócuo (classe 1), de acordo com a IOBC, e portanto, ambos os agentes de controle biológico podem ser utilizados no Manejo Integrado de Pragas.SICONBIOL 2011

Efeito de Metarhizium anisopliae ASH. sobre Telenomus podisi (Hymenoptera: scelionidae).

Os agentes de controle biológico Metarhizium anisopliae e Telenomus podisi são empregados no controle de populações de pragas. Porém na literatura são citados casos de interferência entre agentes de controle. Para serem utilizados concomitantemente, a compatibilidade entre o fungo entomopatogênico e o parasitoide deve ser elucidada. O objetivo deste trabalho foi avaliar os possíveis efeitos do fungo M. anisopliae na eficiência do parasitoide de ovos T. podisi. Os bioensaios foram conduzidos em duas etapas, utilizando ovos não parasitados e ovos parasitados. Na primeira etapa, ovos de Euschistus heros esterilizados aderidos a cartelas (1×2 cm), receberam aplicações de 1,5 ml de suspensão de M. anisopliae (1,0×1010 conídios/ml), em torre de Potter, sendo posteriormente expostos ao parasitismo. Na segunda etapa, suspensões de (1,0×109 conídios/ml) foram pulverizados sobre ovos parasitados. A testemunha recebeu água destilada estéril + Tween 80 (0,01%) em ambos os ensaios. Após as pulverizações, as cartelas foram inseridas em gaiolas de exposição padronizadas pela (IOBC), mantidas em condições controladas de temperatura, umidade e fotoperiodo (25±1º C, 80%, 14:10). Os parasitoides foram alimentados com mel. Para avaliar a porcentagem de parasitismo, emergência e viabilidade dos parasitóides, as cartelas de ovos contendo os parasitoides foram acondicionadas em sacos plásticos, posteriormente observadas em lupa estereoscópica para quantificação e calculo dos parâmetros estudados, Os resultados obtidos indicam que M. anisopliae não afeta o parasitismo de T. podisi, porém a emergência do parasitoide pode ser reduzida quando o fungo é aplicado sobre ovos previamente parasitados. Possivelmente, houve alguma atividade dos fungos sobre os ovos de E. heros que impediram a emergência de T. podisi e fatores físicos e bioquímicos podem estar envolvidos durante a infecção e penetração pelo córion. Entretanto, a redução da viabilidade do parasitismo quando o fungo foi aplicado em ovos parasitados foi percentualmente pequena. Por tanto, M. anisopliae é inócuo e seletivo a T. podisi, e ambos podem ser utilizados no manejo de pragas, preferencialmente quando as aplicações do fungo e liberações do parasitoide sejam realizadas em momentos diferentes para conseguir maior eficiência.SICONBIOL 2011

Immunoblot analysis of the seroreactivity to recombinant Borrelia burgdorferi sensu lato antigens, including VlsE, in the long-term course of treated patients with Erythema migrans

Objective: We evaluated whether immunoblotting is capable of substantiating the posttreatment clinical assessment of patients with erythema migrans ( EM), the hallmark of early Lyme borreliosis. Methods: In 50 patients, seroreactivity to different antigens of Borrelia burgdorferi sensu lato was analyzed by a recombinant immunoblot test (IB) in consecutive serum samples from a minimum follow-up period of 1 year. Antigens in the IgG test were decorin- binding protein A, internal fragment of p41 (p41i), outer surface protein C (OspC), p39, variable major protein-like sequence expressed (VlsE), p58 and p100; those in the IgM test were p41i, OspC and p39. Immune responses were correlated with clinical and treatment-related parameters. Results: Positive IB results were found in 50% before, in 57% directly after therapy and in 44% by the end of the follow-up for the IgG class, and in 36, 43 and 12% for the IgM class. In acute and convalescence phase sera, VlsE was most immunogenic on IgG testing 60 and 70%), and p41i (46 and 57%) and OspC (40 and 57%) for the IgM class. By the end of the follow-up, only the anti-p41i lgM response was significantly decreased to 24%. Conclusions: No correlation was found between IB results and treatment-related parameters. Thus, immunoblotting does not add to the clinical assessment of EM patients after treatment. Copyright (c) 2008 S. Karger AG, Basel

Charge neutralization in vacuum for non-conducting and isolated objects using directed low-energy electron and ion beams

We propose using ions and electrons of energy 1 eV–10 eV for neutralizing the charges on the non-conducting or isolated surfaces of high-sensitivity experiments. The mirror surfaces of the test masses of the laser interferometer gravitational observatory are used as an example of the implementation of this method. By alternatively directing beams of positive and negative charges towards the mirror surfaces, we ensure the neutralization of the total charge as well as the equalization of the surface charge distribution to within a few eV of the potential of the ground reference of the vacuum system. This method is compatible with operation in high vacuum, does not require measuring the potential of the mirrors and is expected not to damage sensitive optical surfaces

Establishing a Reference Baseline for Midday Stem Water Potential in Olive and Its Use for Plant-Based Irrigation Management

Midday stem water potential (SWP) is rapidly becoming adopted as a standard tool for plant-based irrigation management in many woody perennial crops. A reference or “baseline” SWP has been used in some crops (almond, prune, grape, and walnut) to account for the climatic influence of air vapor pressure deficit (VPD) on SWP under non-limiting soil moisture conditions. The baseline can be determined empirically for field trees maintained under such non-limiting conditions, but such conditions are difficult to achieve for an entire season. We present the results of an alternative survey-based approach, using a large set of SWP and VPD data collected over multiple years, from irrigation experiments in olive orchards located in multiple countries [Spain, United States (California), Italy, and Argentina]. The relation of SWP to midday VPD across the entire data set was consistent with an upper limit SWP which declined with VPD, with the upper limit being similar to that found in Prunus. A best fit linear regression estimate for this upper limit (baseline) was found by selecting the maximum R2 and minimum probability for various upper fractions of the SWP/VPD relation. In addition to being surprisingly similar to the Prunus baseline, the olive baseline was also similar (within 0.1 MPa) to a recently published mechanistic olive soil-plant-atmosphere-continuum (SPAC) model for “super high density” orchard systems. Despite similarities in the baseline, the overall physiological range of SWP exhibited by olive extends to about −8 MPa, compared to about −4 MPa for economically producing almond. This may indicate that, despite species differences in physiological responses to low water availability (drought), there may be convergent adaptations/acclimations across species to high levels of water availability. Similar to its use in other crops, the olive baseline will enable more accurate and reproducible plant-based irrigation management for both full and deficit irrigation practices, and we present tentative SWP guidelines for this purpose
