Different Effects of Penconazole on Enzymatic and Non-enzymatic Antioxidants of Sesame (Sesamum indicum L.) Under Salinity _ Crimson Publishers


Different Effects of Penconazole on Enzymatic and Non-enzymatic Antioxidants of Sesame (Sesamum indicum L.) Under Salinity by Niknam V* in Modern Concepts & Developments in Agronomy_ Agronomy open access journals

 

Abstract

Salinization of soil is recognized as one of the most pressing environmental challenges to resolve for the next century. The ability to respond to environmental stimuli is among the most fundamental processes that enable plants to survive. Penconazole (PEN), a triazole group of fungicide, which has both fungicidal and plant growth regulator properties, protects plants from several types of abiotic stresses. The purpose of this work is to assess the effect of sodium chloride (0, 50, 100, and 200mM) and PEN (15mg/L) on some biochemical responses of sesame. Results revealed that some growth parameters decreased under salinity however, compatible solutes, H2O2 and Malondialdehyde (MDA) levels, flavonoid content, and PPO enzyme activity increased. PEN application had a positive effect on growth parameters, proline and H2O2 contents, SOD, CAT and POX enzyme activities, but decreased MDA, carbohydrate, flavonoid and anthocyanin contents, as well as PPO activity. According to our results, PEN changed physiological and biochemical parameters, and therefore, due to its low price and availability is suggested for reduction of the negative effects of salinity in sesame

Keywords: Penconazole; Salt stress; Sesamum indicum L.; Tolerance

Lessons from Masters World Records: Lack of Gender Differences In Aging Muscle Decay Rates_ Crimson Publishers


Lessons from Masters World Records: Lack of Gender Differences In Aging Muscle Decay Rates by Albertin G* in Research & Investigations in Sports Medicine_ Journal of Sports Medicine

 

Abstract
The physiology and physiopathology of muscle aging differ between female sand males. Here, our aim is to investigate gender differences in the rate of the age-related decay of skeletal muscle performance using a complete series of female and male normalized master’s world records. Masters athletes compete in age groups of five-year divisions and range from 35 to 100 years of age. The world records are lists of up to 16 data points that, after normalization, can be interpolated with polynomial trend-lines with a high R2. Gender comparisons were performed for 19 Track and Field specialties using weighted regression analyses. As expected, the aging decline began at 35 years for both the women and men. Despite differences in the 19 Track and Field Masters world records for female and male athletes in the same age groups, in comparing the normalized female and male Masters athlete world records, the rates of aging performance decay were very similar if not identical. This lack of gender difference is a unique exception to the general rule of gender differences in sports activities, suggesting that neuro-hormonal mechanisms poorly influence the rate of aging muscle power decay. We then discuss the hypothesis that age-induced decline is related to fundamental cellular mechanisms, perhaps those that control energy metabolism. The limitations and implications of our hypothesis are discussed as well.
