The antioxidant activity of aqueous extracts of fresh leaves of costmary (Chrysanthemum balsamita L.) was investigated. The effect of the extraction time on total phenolic compounds (TPhC) and antioxidant activity (ABTS -, CUPRACand FRAP assays) was studied. Results demonstrated highest levels of TPhC (0.60 GAE/g fresh plant weight), CUPRAC (5.93 μMTE/g FW), ABTS (10.68 μMTE/g FW), and FRAP (7....

background and objectives:alzheimer’s disease (ad) is a neurodegenerative disorder. nowadays, many investigations are performed to find new drugs for ad and medicinal plants are considered as one of the most important sources for developing new drugs. according to the role of oxidant agents and acetylcholinesterase enzyme (ache) in ad, plants with antioxidant and ache inhibition properties coul...

Typical microscopic methods used for characterizing intracellular protein mobility are, e.g., fluorescence photobleaching recovery (FRAP) and fluorescence correlation spectroscopy (FCS). Of these, FRAP can image protein mobility in entire two-dimensional sections of live cells, but is typically limited to the time resolution of confocal image series, some frames per second. FCS, on the other ha...
