Salicylic acid 3% / Hydrous wool fat 25% in Yellow soft paraffin

Secondary metabolites are highly beneficial to human health and have commercial and industrial values. So, this research aimed to study the effects of exogenous salicylic acid (SA) and jasmonic acid (JA) on some secondary metabolites in purple coneflower. A field experiment as a randomized complete block design with three replications was conducted in Shahrood, Iran. Treatments were the factorial arrangement of 3 SA (0, 0.5, and 1 millimole) and 4 JA concentrations (0, 5, 20, and 50 micromole). The non-linear regression procedure was employed to quantify the relation of these materials with each other. The results indicated that the SA effect on all ten measured secondary metabolites changed with changing the JA levels as there was the interaction between these elicitors. On average, most (7 out of 11) of the combined SA_JA levels up-regulated the production of secondary metabolites as compared to the plants not sprayed with SA and JA. In terms of average response to elicitation with 11 combined SA_JA levels, they ranked from higher to lower as the guaiacol peroxidase, hydrogen proxide (H2O2), polyphenol oxidase, glutathione S-transferase, superoxide dismutase, NADPH oxidase, total phenolic content, phenylalanine ammonia-lyase, anthocyanin, and flavonoid. A few secondary metabolites appeared to have a biphasic relationship with each other. For instance, over lower and medium values of NADPH oxidase activity, anthocyanin content increased linearly with increasing NADPH oxidase activity; over higher values of NADPH oxidase activity, it showed a plateau state.

The researches were carried out on sheep of the Kazakh Kurdy semi-coarse wool breed: rams of producers of the Bayyssk type of the same breed were used on uteruses of the Kargali inbreed type. The level and dynamics of live weight for the suckling period and up to 16 (yarki) months of age, as well as slaughter and meat qualities of rams of 2 and 4 months of age were studied in the obtained offspring. The level of live weight for all the studied age periods was the highest in the young stock obtained from crossing of Kargali inbred type mothers with rams of Bayys type producers, the superiority amounted to 6.0-3.9% at birth (rams - yarochki), 4.3-3.3% at weaning and 2.7% at 16 months of age (yarki). The study of features of articles of physique of 4 and 16 months old yaks showed that in these age periods yarks with genotype KPG-B × KPG-K have an advantage over purebred Kargalinsky coevals KPG-K by all measures of physique. In terms of slaughter indices, KPG-B × KPG-K lambs had superiority over purebred Kargala lambs at both age periods of slaughter

Aspirin is used for a variety of reasons, from reducing fever to providing relief for mild pain associated with headaches, menstrual cramps, and arthritis. Its versatility leads to aspirin tablets being present in almost every home, which makes the consequences of their mishandling that much more impactful. Generally, patients are instructed not to store aspirin in areas exposed to excess heat and humidity as they cause aspirin to break down into salicylic acid and acetic acid. Salicylic acid is the substance responsible for aspirin’s medicinal properties, and fluctuations in its concentration can lead to dosage inaccuracies. This leads to questions and concerns about the correlation between temperature and the concentration of salicylic acid within hydrolyzed aspirin. Within this paper, it was found that there is a directly proportional relationship between temperature and the concentration of salicylic acid in acetylsalicylic, as the concentration steadily increases as the temperature increases.
