Biofilm removal efficacy of vortexing alone was compared with the standard vortexing-sonication procedure. Among 135 removed prostheses, 35 were diagnosed with infection and 100 with aseptic failure. At a cutoff of ≥ 50 CFU/ml, sonication was more sensitive than vortexing (60% versus 40%, P = 0.151), while the specificity was 99% for both methods.

Introduction: A recent development in the treatment of uterine fibroids is the use of magnetic resonance guided high intensity focused ultrasound (MR-HIFU), which has been tested in several clinical trials and has been approved for clinical use in several countries In a traditional MR-HIFU treatment, a single focal point is iteratively sonicated at a time until the desired volume is ablated, wi...

The influence of tip sonication duration on the spectral characteristics of carbon single-walled nanotubes (SWNTs) in aqueous suspension with single-stranded DNA (ssDNA) has been studied by NIR luminescence, NIR absorption, and Raman spectroscopy. It was revealed that prolongation of sonication leads to weakening of the SWNT polymer coverage and appearance of additional defects on the nanotube ...

Transdermal drug delivery makes a critical contribution to medical practice and some advantages over conventional oral administration and hypodermic injection. Enhancement of percutaneous absorption or penetration of therapeutic agents (ie, drugs and macromolecules) by ultrasound, termed sonophoresis, has been applied and studied for decades. In this study, the penetration percentage through po...

conclusions anova results showed that the effect of cycle and time on the selected bacterial removal efficiency were more important than that of the microbial concentration. results the results showed that e. coli and e. faecalis were effectively treated at 10 pulse/s in 9 minutes and 6 log cfu/ml bacterial suspension (p < 0.0001 for e. coli with 99.99% (4 log) and p = 0.0002 for e. faecalis wi...

Nowadays, electrospray is becoming a favourable approach for preparing monodispersed nanoparticles. However, this approach is quite recent and requires further works to optimize control over physicochemical properties of its products. This study aimed to determine the possible effects of sonication as a pretreatment to reduce the size of azelaic acid-chitosan particle before using electrospray....

Background: Pineapple juice processing is an art of preservation, and the processing technologies play important role in pineapple juice quality. Therefore, this study aimed to explore the potential impacts of non-thermal processing methods on the physicochemical, bioactive, and microbiological properties of fresh pineapple juice. Methods: Extracted juices were subjected to several non-thermal...

Background and purpose - The correct diagnosis of prosthetic joint infection (PJI) can be difficult because bacteria form a biofilm on the surface of the implant. The sensitivity of culture from sonication fluid is better than that from periprosthetic tissue, but no comparison studies using molecular methods on a large scale have been performed. We assessed whether periprosthetic tissue or soni...

Two  simple  protocols  for  the  synthesis  of  1,  2,  4,  5-   tetrasubstitutedimidazoles  using  nano-SPA  as  a  reusable,  eco-   friendly,  inexpensive,  and  efficient  catalyst  are  reported.  Short   reaction  times,  high  yields,  scale-up  and  easy  workup  are  the   advantages of these protocols.
