Three experimental paradigms for examining defense mechanismsPaulhus, Delroy LPaulhus, D. L. (1990). Three experimental paradigms for examining defense mechanisms. Polish Psychological Bulletin, 21, 345-351.
The tentative HPLC–MS identification of phytohormone-like substances, such as gibberellin A2 and zeatin, or the antioxidant acetyl eugenol, may partially explain the mechanisms of L. multiflorum plant growth promotion after the application of fungal filtrates and/or extracts....
Since these receptors probably function in part through independent signaling pathways, MPSS may function at a common site related to vesicular trafficking. Further investigation is needed to determine the specific means by which corticosteroids interfere with neutrophil upregulation mechanisms. 展开 关键词...
Nevertheless, alternative mechanisms could supply cells with phosphatidylinositol, phosphatidylcholine, inositol and choline (Fig. 4; Supplementary Note 5). Strikingly, most of the genes involved in fatty acid b-oxidation are missing in all three species, suggesting that fatty acids are not an energy...
Common metabolites of this dataset are presented in Fig. 6. Full size image To summarize: two thirds of compounds were detected in roots and exudates of all plant species, comprising the root and the exudate core metabolome. We speculate that the latter is of importance for interaction with ...
Grana, as well as probablyOsparvis, belong to Phygadeuontinae, which is the most abundant ichneumonid subfamily in Baltic amber and is also very common in temperate forests today16,20. Phygadeuontinae are idiobiont ectoparasitoids of a diverse range of hosts that are more or less concealed...
The most common of these beneficial defense mechanisms is a pump protein, P-glycoprotein or P-gp, as it's called. Another is one seen in breast and many other cancers, called breast cancer resistance protein, BCRP. In the case of cancer cells on the first round of treatment, these pumps...
An interesting revision of this part of the model was suggested by Stokes (1997) who suggested it might be possible to distinguish between lines of scientific research which might be ‘use-inspired’ (e.g. Pasteur’s investigations into the mechanisms of fermentation) from those that are ‘pure...
such as protein translation and transport. Plant viruses must also overcome antiviral defence mechanisms, such as post-transcriptional gene silencing, to create a favourable environment that supports their life cycles. How plant viruses can perform all these tasks on their own is still a matter of ...
The occurrence of these concurrent extremes raises questions about association mechanisms and forcing sources, it is important for forecasting and implementing global defense strategies and mitigation measures. Anthropogenic forcing, resulting from human activities, contributes to the amplification of both the...
