Salicylic acid (SA) is a likely endogenous signal in the development of systemic acquired resistance (SAR) in some dicotyledonous plants. In tobacco mosaic virus (TMV)-resistant Xanthi-nc tobacco, SA levels increase systemically following the inoculation of a single leaf with TMV. To determine the extent to which systemic increases in SA result from SA export from the inoculated leaf, SA produc...
BACKGROUND Staphylococcus aureus (SA) is a leading cause of infectious diseases in sports teams. In recent decades, community-associated SA (CA-SA) strains have emerged worldwide and have been responsible for outbreaks in sports teams. There are very few data on the prevalence of these strains in France, and none on the carriage among athletes. METHODS We conducted a cross-sectional study to ...
The phenomenon of situational awareness (SA) has received considerable attention in recent years and significant theoretical advances have been made which establish that SA is an important component of teamwork. This is especially true in complex environments, such as in command and control, where the team is required to deal with decision-making problems under significant pressure. Two models ...
Plant defenses induced by salicylic acid (SA) are vital for resistance against biotrophic pathogens. In basal and receptor-triggered immunity, SA accumulation is promoted by Enhanced Disease Susceptibility1 with its co-regulator Phytoalexin Deficient4 (EDS1/PAD4). Current models position EDS1/PAD4 upstream of SA but their functional relationship remains unclear. In a genetic and transcriptomic ...
Human milk compared with infant formulas contains considerably more sialic acid (SA) and cholesterol. Because both compounds accumulate rapidly in the frontal cortex in infancy, it has been suggested these compounds may be conditionally essential nutrients for brain development. A limited number of animal studies demonstrate that dietary cholesterol and SA increase cortical cholesterol and SA c...
Linkage analyses in experimental crosses of hypertensive and normotensive rats have strongly suggested the presence of a quantitative trait locus (QTL) influencing blood pressure on rat chromosome 1, at or near the Sa gene. To confirm the presence of such a locus and move toward identification of the causative gene, we have developed, through targeted breeding over 10 generations using an Sa ge...
Salicylic acid (SA) is an important hormone involved in many diverse plant processes, including floral induction, stomatal closure, seed germination, adventitious root initiation, and thermogenesis. It also plays critical functions during responses to abiotic and biotic stresses. The role(s) of SA in signaling disease resistance is by far the best studied process, although it is still only part...
Systemic induction of pathogenesis-related (PR) proteins in tobacco, which occurs during the hypersensitive response to tobacco mosaic virus (TMV), may be caused by a minimum 10-fold systemic increase in endogenous levels of salicylic acid (SA). This rise in SA parallels PR-1 protein induction and occurs in TMV-resistant Xanthi-nc tobacco carrying the N gene, but not in TMV-susceptible (nn) tob...
این آزمایش روی گلهای شاخه بریده رز رقم ‘ردنائومی’ و ‘آوالانج’ با طول 40 سانتی متر، به مدت 18 ساعت بصورت تیمار کوتاه مدت(پالسینگ) بر پایه آزمایش کاملاً تصادفی با 5 تیمار شیمیایی: ساکارز + هیدروکسی کوئینولین سولفات (suc+hqs) ، ساکارز+ هیدروکسی کوئینولین سولفات+ سالسیلیک اسید(suc+hqs+sa)، ساکارز+ هیدروکسی کوئینولین سولفات+ آسکوربیک اسید (suc+hqs+asa) ، ساکارز + هیدروکسی کوئینولین سولفات+ سالسیلیک ا...
Female (n = 5,226) and male (n = 5,969) U.S. Navy recruits completed a survey assessing their premilitary histories of adult sexual assault (SA), defined as attempted or completed rape since the age of 14. The survey was completed under anonymous or identified conditions. Overall, 39% of women reported premilitary SA victimization and 13% of men admitted premilitary SA perpetration. As predicte...
