Abstract: A method for preparing block polyether amide foamed particles with sandbag structure includes: premixing modifier, filler and coupling agent, melting and blending the premixed raw materials, and preparing blended particles I with core-shell structure after underwater granulation or water tank granulation; premixing the blended particles I with block polyether amide raw material, melting and blending the premixed raw material, and preparing block polyether amide blended particles II with sandbag structure after underwater granulation or water tank cutting; putting the quantitative blended particle II into an autoclave, introducing quantitative environment-friendly physical foaming agent until the foaming agent and G2 blende particles reach a homogeneous system, evacuating autoclave pressure through a valve, and taking out block polyether amide blended particles III containing the foaming agent; and transferring the blended particles III into a thermostatic equipment at softening temperature of particles, and o

Abstract: Pathogenic effector proteins which include one or more RxLR, dEER, Pexel or analogous motifs are blocked from entry into plant or animal cells by binding one or more of the motifs with a blocking compound which prevents binding of phosphoinositides or other polar lipids to the motifs which is a prerequisite for translocation of the pathogenic effector proteins into the plant or animal cell. The blocking compounds can take a variety of forms including synthetic peptides or the hydrophilic head-groups of phosphoinositides, phosphatidic acids, phospholipids, or sphingolipids. Suitable blocking compounds can be identified by assays demonstrating binding to RxLR, dEER, Pexel or analogous motifs. In addition, pathogenic effector proteins can be identified by analyzing whether they contain structural RxLR motifs using hidden markov modeling.
