Cyclin-dependent kinase 5 (CDK-5) appears to play a significant role in peripheral nerve regeneration as CDK-5 inhibition retards nerve regeneration following nerve crush. Anti-inflammatory drug acetyl salicylic acid elevates CDK-5 and reduces ischemia - reperfusion injury in cultured neurons. In this study we have evaluated the effect of acetyl salicylic acid on functional recovery following s...

Stem and peduncle bending by the weight of the flower is one of the main postharvest problems in gerbera (Gerbera jamesonii Bolus.) and sometimes caused stem crushing or water loss. In this research, silicon and salicylic acid were applied to enhance the mechanical strength of inflorescence stem, and the results revealed that stem curving was decreased by silicon and salicylic acid treatments. ...

Maize seedling water relations and abscisic acid (ABA) levels were measured over 24 h of root chilling (5.5 degrees C). At 2.5 h into chilling, leaf ABA levels increased by 40x and stomatal conductance (g(s)) decreased to 20% compared with prechill levels. Despite a rapid g(s) response to root chilling, leaf water potential (Psi(L)) of chilled seedlings decreased to -2.2 MPa resulting in a comp...

This experiment was conducted to study the effect of salicylic acid and methyl jasmonate as preharvest treatments on the tomato vegetative growth, yield and fruit quality. The experiment was completely randomized experimental design with four replications. These factors included salicylic acid in 2 levels (0.5 and 0.75 mmolL-1) and methyl jasmonate in 3 levels (0.25, 0.5 and 0.75 mmolL-1) appli...

The importance of p-aminosalicylic acid in the treatment of tuberculosis has been demonstrated both clinically and experimentally (l-6). The close structural relationships between benzoic, salicylic, p-aminobenzoic (PABA), and p-aminosalicylic (PASA) acid warrant a comparative study of the metabolism of these substances in the animal body.* Recent workers, interested in the behavior of PABA in ...

A chilling-sensitive mutant of Arabidopsis thaliana was isolated and subjected to genetic, physiological, and biochemical analysis. The chilling-sensitive nature of the mutant line is due to a single recessive nuclear mutation at a locus designated chs1. In contrast to wild-type plants, which are not adversely affected by low temperatures, the chs1 mutant is killed by several days of exposure t...

Diacylglycerol (DAG) is likely converted to triacylglycerol (TAG) by the enzyme diacylglycerol acyltransferase (DGAT), and this conversion important in freezing tolerance of Arabidopsis. The phytohormone salicylic acid (SA) DAG/TAG ratio are known play roles chilling Arabidopsis while interaction or connection was not clear. In our study, we analysed phenotype, proline sugar accumulation, conte...

this experiment was carried out as factorial based on randomized complete block design with four replications in 2011-2012 growing season. the experimental factors were selenium in four levels 0, 6, 12 and 18 g ha-1 and salicylic acid in three levels 0, 100 and 200 mg l-1. results showed that foliar application of selenium at rate of 12 and 18 g ha-1 decreased ion leakage by 11.6 and 18.8% comp...

To elucidate how physiological and biochemical mechanisms of chilling stress are regulated by abscisic acid (ABA) pretreatment, pepper variety (cv. 'P70') seedlings were pretreated with 0.57 mM ABA for 72 h and then subjected to chilling stress at 10°/6°C (day/night). Chilling stress caused severe necrotic lesions on the leaves and increased malondialdehyde and H(2)O(2) levels. Activities of mo...

UNLABELLED Data emerging from the past 10 years have consolidated the rationale for investigating the use of aspirin as a chemopreventive agent; however, the mechanisms leading to its anticancer effects are still being elucidated. We hypothesized that aspirin's chemopreventive actions may involve cell-cycle regulation through modulation of the levels or activity of cyclin A2/cyclin-dependent ki...
