Salicylic acid (SA) plays many roles in plant physiology. Besides pathogenesis-related resistance, SA is involved in the response to abiotic stress. However, the effects of SA on plant resistance to abiotic stress were found contradictionary, and the actual role of SA in abiotic stress remains unresolved. Generally, deficiency of SA or a very high level of SA increase the plant susceptibility t...

The goal of this research is (a) to investigate the effects of task practice on situation awareness (SA); (b) to investigate how cognitive ability – in particular, working memory – moderates this practice effect on SA; and (c) to investigate effects of the SA measurement procedure (covering or uncovering the display while queries are answered). Task practice and working memory influence SA. How...

We previously proposed that salicylic acid (SA)-sensitive catalases serve as biological targets of SA in plant defense responses. To further examine the role of SA-sensitive catalases, we have analyzed the relationship between SA levels and SA sensitivity of catalases in different rice (Oryza sativa) tissues. We show here that, whereas rice shoots contain extremely high levels of free SA, as pr...

There has been little investigation of the effects of past substance abuse (SA) on working memory (WM) impairments in schizophrenia. This study examined the behavioral and neurobiological impact of past SA (6 months or longer abstinence period) on WM in schizophrenia. Thirty-seven schizophrenia patients (17 with past SA and 20 without) and 32 controls (12 with past SA and 20 without) completed ...

BACKGROUND Fibrosis or fatty infiltration of the human sinoatrial (SA) node is generally believed to represent replacement of the SA nodal cells by connective tissue. Quantitative analysis, however, has not been performed precisely to validate the interpretation of such histological changes. METHODS AND RESULTS The actual volume of the SA node and its components were calculated according to t...

The small phenolic compound salicylic acid (SA) is critical for plant defense against a broad spectrum of pathogens and responses to different abiotic stress conditions. Particularly in response to pathogens, SA is involved in multiple processes, including basal and resistance gene-mediated defense as well as systemic acquired resistance (SAR). This Research Topic includes a collection of 18 ar...
