The methanol extracts of the various plant parts were screened for anti-oxidant activity by thin layer chromatography using 2,2-diphenyl-1-dipicrylhydrazyl (DPPH) while in vitro antimicrobial evaluation was determined agar diffusion method and bioautographic technique Escherichia coli, Bacillus subtilis, Staphylococcus aureus Pseudomonas aeruginosa as test organisms; aqueous solvent served cont...

Background: Skin reflects the general health status and is not an exception in the process of aging. Intervention studies indicate that it is possible to delay skin aging and improve skin conditions through diet-based anti-aging strategies. The purpose of the current work was to review recent existing literature regarding the role of nutrition, for and against skin aging processes.Method: This ...

Abstract: The use of computational resources to assess the physiological potential seeds has attracted attention researchers and professionals in seed sector. aim this study was evaluate vigor cowpea using Vigor-S software (Automated Seed Vigor Analysis System), comparison information provided by traditional tests that are recommended for species. Seven lots cultivar BRS Guariba were used. They...

Protein phosphatase 2A (PP2A) is a critical target to control cumulative oxidative stress and chronic inflammation during skin aging by reversible methylation of the C-terminal leucine PP2A catalytic subunit (PP2Ac). A novel, proprietary Activated-Grape Seed Extract (AGSE), enriched for PP2A-activating flavonoids, was recently developed, has demonstrated potent antioxidant anti-inflammatory act...

high variability in delivering the target torque is reported for friction-style mechanical torque limiting devices (f-s mtlds). the effect of aging (number of use) on the accuracy of these devices is not clear. the purpose of this study was to assess the effect of aging on the accuracy (±10% of the target torque) of f-s mtlds.fifteen new f-s mtlds and their appropriate drivers from three differ...

in this paper, the effect of prestrain on strain aging of low carbon steels, in the temperatures of 100°c and 200°c and the aging time of 50 minutes, and also the effect of aging temperature on strain aging in a constant aging time and prestrain, are investigated. the results of experiments show that with increasing the amount of prestrain, the increase in yield stress and ultimate tensile stre...
