متن کاملMechanistic Studies of Ultrasonically-Enhanced Transdermal Drug Delivery
Transdermal drug delivery (TDD), a painless, non-invasive method of drug delivery, is limited to only a handful of drugs due to the low permeability of skin, The application of low frequency ultrasound significantly enhances transdemal transpor[ of a variety of drugs (sonophoresis), most likely through cavitation-related phenomena. It is unclear whether the primary effect of ultrasound is on th...
متن کاملEnhanced ultrasonically assisted turning of a β-titanium alloy.
Although titanium alloys have outstanding mechanical properties such as high hot hardness, a good strength-to-weight ratio and high corrosion resistance; their low thermal conductivity, high chemical affinity to tool materials severely impair their machinability. Ultrasonically assisted machining (UAM) is an advanced machining technique, which has been shown to improve machinability of a β-tita...
متن کاملUltrasonically enhanced rifampin activity against internalized Staphylococcus aureus
Staphylococcus aureus (S. aureus) is the principle causative agent of osteomyelitis, accounting for 80% of all human cases. S. aureus internalized in osteoblasts escapes immune response, including engulfment by phagocytes. It also escapes the action of a number of antibiotics. Ultrasound increases cell membrane permeability to a number of drugs. Following an internalization assay, we used low-f...
متن کاملEnergy enhancement in time-reversed ultrasonically encoded optical focusing using a photorefractive polymer.
Time-reversed ultrasonically encoded (TRUE) optical focusing achieves light focusing into scattering media beyond one transport mean free path, which is desirable in biomedical optics. However, the focused optical energy needs to be increased for broad applications. Here, we report the use of a photorefractive polymer (PRP) as the phase conjugate mirror in TRUE optical focusing. The PRP boosted...
