Sir, Ultrasonography (USG) is nowadays routinely used in anesthesia and critical care practice for nerve blocks, central venous cannulation, and tapping of pleural or pericardial effusions. There have been reports of bacterial infections transmitted through ultrasound probe and coupling gel.[1] To prevent or minimize the risk of infection, USG probe and its cable are generally wrapped in commer...

In 2009, prostate cancer ranked as the most common cancer and the second most fatal cancer in men in the United States. Unfortunately, the current clinical diagnostic methods (e.g. prostate-specific antigen (PSA), digital rectal examination, endorectal MRI, transrectal ultrasound, biopsy) used for detecting and staging prostate cancer are limited. It has been shown that cancerous prostate tissu...

The effect of ultrasound in combination heat on the extraction yield and technological properties chia seed mucilage was investigated. Chia seeds were mixed with distilled water at a seed-to-water ratio 1:30. dispersion adjusted to pH 9 treated either by bath or heat/ultrasound probe-type sonication 50 °C 80 for 30 60 min. samples evaluated. gave greater (6.92–10.52%) as compared (1.03–1.86%). ...

Microdialysis is a method by which compounds can be studied in the extracellular space in skin, in vivo. The microdialysis probe is inserted in the dermis using a guide cannula. It is expected that intradermal oedema associated with insertion trauma as well as the probe depth can influence the results of microdialysis studies. The aim of the present study was to assess the effects of insertion ...

This work demonstrates the feasibility of using high intensity focused ultrasound (HIFU) for selective ablation of renal tissue through laparoscopic procedures. Two laparoscopic HIFU probe prototypes were developed and tested. Probe 1: It is a hand-held probe with no integrated ultrasound imaging capability. It consists of two focused rectangular HIFU piezoceramic crystals mounted on a stainles...

The aim of this paper is to study the effect of substrate on the Cu3N thin films. At first Cu3N thin films are prepared using DC magnetron sputtering system. Then structural properties, surface roughness, and electrical resistance are studied using X-ray diffraction (XRD), the atomic force microscope (AFM) and four-point probe techniques respectively. Finally, the results are investigated and c...
