Multicase study on product design in the area of assistive technology in Brazil.

The present research aims to contribute to the comprehension of the product development process (PDP) of Assistive Technology (AT) through methodological multi-case studies in Brazil. The following considerations presented in the study are part of a Master's degree thesis, conducted from 2013 to 2015. The research adopted a multi-case study methodology by selecting four product developers from the Assistive technology field in Brazil, focusing on physical disability.

A feedback regulatory loop between G3P and lipid transfer proteins DIR1 and AZI1 mediates azelaic-acid-induced systemic immunity.

Systemic acquired resistance (SAR), a highly desirable form of plant defense, provides broad-spectrum immunity against diverse pathogens. The recent identification of seemingly unrelated chemical inducers of SAR warrants an investigation of their mutual interrelationships. We show that SAR induced by the dicarboxylic acid azelaic acid (AA) requires the phosphorylated sugar derivative glycerol-3-phosphate (G3P).
