Biochemical characterization of activation associated bovine class I major histocompatibility complex antigens por Bensaid, A.M., Kaushal, A., MacHugh, Niall D., Shapiro, S.Z., Teale, A.J.

“…Sequential immunoprecipitations performed with the mAb revealed that class I molecules on PBM comprise a single population with respect to reactivity with the mAb in that the β2m‐associated proteins bear all three epitopes. By contrast, TCGF‐driven lymphoblasts and cells transformed by Theileria parva (Tp) additionally express molecules of Mr 45000 bound to β2m which are recognized by mAb B1G6 and IL‐A19 but not by W6/32. …”

Tick salivary gland extract and interleukin-2 stimulation enhance susceptibility of lymphocytes to infection by Theileria parva sporozoites por Shaw, M.K., Tilney, L.G., McKeever, Declan J.

“…The IL-2-induced increase in host cell susceptibility could be prevented by treating the lymphocytes with the monoclonal antibody IL-A 111, which reacts with the bovine IL-2 receptor alpha chain and inhibits IL-2-driven cell proliferation. The changes induced by tick salivary gland extract and IL-2 occurred in less than 90 min. …”

Estimating ungauged stream flows based on model regionalization: examples from the mountainous, semi-arid Karkheh River Basin, Iran por Masih, Ilyas, Uhlenbrock, Silke, Maskey, S., Ahmad, Mobin-ud-Din, Islam, Aminul

“…FDCs for the ungauged catchments were predicted using logarithmic relationship derived from physiographic characteristics of eleven gauged catchments. The study shows that transferring HBV model parameters based on the FDC similarity criterion produces better runoff simulation compared to the similarity criteria based on catchment area and geographical proximity. …”

Combining remotely sensed surface energy fluxes and GIS analysis of groundwater parameters for irrigation system assessment por Alexandridis, T.K., Panagopoulos, A., Galanis, G., Alexiou, I., Cherif, I., Chemin, Yann H., Stavrinos, E., Bilas, G., Zalidis, G.C.

“…The resulting maps from the proposed methodology show that the performance of the irrigation system varied across space and time due to differences in its characteristics and changes in its operation, driven by fluctuation of water availability and the response of stakeholders to water depletion. …”

Adapting to water scarcity: constraints and opportunities for improving irrigation management in Khorezm, Uzbekistan por Tischbein, B., Manschadi, A.M., Conrad, C., Hornidge, A.-K., Bhaduri, Anik, Ul-Hassan, Mehmood, Lamers, John P.A., Awan, Usman K., Vlek, Paul L.G.

“…Like many irrigation schemes in Central Asia, the one in Khorezm faces a two-fold challenge: on the one side, the severe problems inherited from the past need to be remedied and on the other side, the rising supply-demand gap driven by sharpening competition for water and climate change must be dealt with. …”

A framework for analyzing participatory plant breeding approaches and results por Sperling, L., Ashby, Jacqueline A., Smith, M.E., Weltzien, Eva, McGrath, S.

“…While some have argued that commercial, private sector plant breeding has long been client-driven, or `participatory' under another name, the application of `PPB' to reach poor client groups, to breed for high-stress, heterogeneous environments and to incorporate diverse traits to meet specific client preferences is resulting in fundamental changes in the way plant genetic resources are being managed. …”

QTL mapping of resistance to Thrips palmi karny in common bean por Frei, AM, Blair, Matthew W., Cardona Mejía, César, Beebe, Stephen E., Gu, H, Dorn, S.

“…The QTLs for both traits were located based on single interval mapping (IM) and joint interval mapping (JIM) analysis using a genetic map constructed with microsatellite and random amplified polymorphic DNA (RAPD) markers. Eight of eleven resulting linkage groups (LGs) were shown to be homologous to chromosomes of the integrated linkage map of common bean. …”

Recipes for Change validation report: Papas a la Huancaina in Bolivia por Norman, James

“…CCAFS also identifies the fact that the livelihoods of farmers engaged in potato production in Bolivia are subject to multiple stressors, many of which are linked with (but not primarily driven by) changes in the climate. Alleviation of the risks posed by climate change therefore also entails alleviating risks posed by non-climatic stressors. …”
