On the dynamics of systems with vastly different frequencies حسب Sheheitli, Hiba

"…The method of direct partition of motion (DPM) has been widely used to study the dynamics of non-autonomous oscillatory systems subject to external high frequency excitation. In this work, we explore the non-trivial dynamics that arise in autonomous systems with vastly different frequencies, in which the fast excitation is intrinsic to the system and possibly influenced by the slow dynamics. …"

Effect of High-Frequency Ultrasound on Targeted Liposomes حسب AlSawaftah, Nour Majdi

"…Here, the US-mediated drug release from calcein-loaded non-pegylated, pegylated as well as targeted-pegylated liposomes modified with human serum albumin (HSA) and transferrin (Tf) was investigated. HFUS at two different frequencies (1 MHz and 3 MHz) was found to trigger calcein release, with higher release rates recorded at the lower frequency (1 MHz) compared to the higher frequency (3 MHz) despite a higher power density. …"

Role of frequency and mechanical index in ultrasonic-enhanced chemotherapy in rats حسب Staples, Bryant J.

"…Purpose The therapeutic effect of ultrasound and micellar-encapsulated doxorubicin was studied in vivo using a tumor-bearing rat model with emphasis on how tumor growth rate is affected by ultrasonic parameters such as frequency and intensity. Methods This study employed ultrasound of two different frequencies (20, 476 kHz) and two pulse intensities, but identical mechanical indices and temporal average intensities. …"
