...nt, while the second for ultrasonication treatment, before conducting antimicrobial activities. Zones of inhibition were measured by using disc diffusion method. Supernatant fraction of E. coli was positive against Sal. typhi and supernatant fraction of P. multocida was positive against E. coli, which show that antimicrobial agents were secretory in nature. Sonicated fractions were on second order to produce ant...

...lied through
ultrasonication of Montanide ISA 206 in the presence of Tween 80 as a detergent. The physical
characteristics were studied and imaged by TEM.
Results: Images showed particle size ranged from 200-400 nm instead of 1 micron of the original.
Immunological evaluation by serum neutralization test showed enhanced immunogenicity of
developed formula when compared to the conventional one. Challen...

...ds: This was achieved by ultrasonication of aluminum hydroxide gel in the presence of
trehalose as dispersant and measuring different physical characters including particle size, Zeta
potential, loading capacity and imaging of adjuvant before and after formulation.
Results: Ultrasonication of aluminum hydroxide gel resulted in generation of 120-200 nm gel
structures followed by...

...rrent work describes the ultrasonication assisted extraction followed by comprehensive investigation of antioxidant activity and α-amylase inhibition potential of hydroethanolic leaf extracts of Vitexnegundo. Freeze drying assisted ultrasonicated extraction revealed highest level of total phenolic contents (258.29±2.52 mgGAE/g DE) and total flavonoid content (155.91±1.75 mgRE/g DE) in 60% hydro-ethanolic V. negundo leaf extract. Furthermore...
