Proctolin and an Endogenous Proctolin-Like Peptide Enhance the Contractility of the Limulus Heart [PDF]
, 1983 Synthetic proctolin increases the force but not the rate of heart contractions of Limulus in a time- and dose-dependent manner. The threshold of this effect is 3 × 10−10M and the ED50 is approximately 10−8M. At concentrations up to 10−7 M, proctolin has

Pest Management Science, EarlyView.SCB has a robust RNAi response to injected dsRNA, but oral RNAi is less efficient. Nucleases do not appear to be responsible for the discrepancy, suggesting other factors are involved. Abstract BACKGROUND The striped cucumber beetle (SCB) is a serious pest of cucurbit crops, causing damage both by feeding on plants and by vectoring plant diseases ...

Pest Management Science, EarlyView.We isolated Zymoseptoria tritici strains from a diverse wheat field and quantified fungicide resistance using a novel plate assay. We found high diversity in fungicide sensitivity and host–fungicide–pathogen interactions. Abstract BACKGROUND Zymoseptoria tritici causes Septoria tritici blotch (STB), the most damaging wheat disease in Europe. In Europe,

Are plants with anti-cancer activity resistant to crown gall? : A test of hypothesis [PDF]
, 2007 The Crown gall tumour assay (CGTA) is one of several bench top bioassays recommended for the rapid screening of plants with anti-cancer activity. The rationale for the use of the bioassay is that the tumorogenic mechanism initiated in plant tissues by ...

The Annals of Statistics, 1983 A Bayesian treatment of the quantal bioassay design problem is given. It is assumed that the potency curve is a Dirichlet random distribution $F$ with parameter $\alpha(t) = MF_0(t)$, and that $n_1, \cdots, n_L$ animals are treated at drug levels $t_1, \cdots, t_L$ respectively.

Pest Management Science, EarlyView.Tebuconazole‐resistant isolates overexpress CYP51 and, when tested at field rates, did not reduce ABS severity, whereas difenoconazole and mefentrifluconazole remained effective. Abstract BACKGROUND Alternaria brown spot (ABS), caused by Alternaria spp., is an important disease affecting mandarin production in several citrus‐growing regions worldwide ...
