conclusions open gastrostomy was successfully performed under subcostal tap block with small dose fentanyl supplementation. the subcostal tap block is considered a useful anesthetic choice in surgery for high risk patients. introduction many papers have reported that tap block provides effective postoperative analgesia, but the sole use of tap block for surgical anesthesia has been rarely repor...

BACKGROUND Transrectal ultrasound-guided prostate needle biopsies are performed to diagnose prostate cancer. This study prospectively evaluated the safety, morbidity and complication rates with two different ultrasound probes. PATIENTS AND METHODS Three huntred and thirty-two patients were biopsied using a biplane 7.5 MHz probe (GE Medical Systems Kretz Ultrasound, Zipf, Austria) and 101 pati...

PLACE AND DURATION OF STUDY Radiology Department, the Aga Khan University Hospital, Karachi and Microbiology Department, JPMC, Karachi, from December 2006 to April 2007. PATIENTS AND METHODS A total of 75 culture swa...

scanning impedance microscopy (sim) is one of the novel scanning probe microscopy (spm) techniques, which has been developed to taking image from sample surface, providing quantitative information with high lateral resolution on the interface capacitance, and investigating the local capacitance–voltage (c–v) behavior of the interface and ac transport properties. the sim is an ordinary afm equip...

the scanning probe microscopes (spms) based lithographic techniques have been demonstrated as an extremely capable patterning tool. manipulating surfaces, creating atomic assembly, fabricating chemical patterns, imaging topography and characterizing various mechanical properties of materials in nanometer regime are enabled by this technique. in this paper, a qualified overview of diverse lithog...

An experiment set-up is used to study wall deposition rate of particles on a rough surface in a turbulent channel flow. Deposition velocities for three classes of particles, namely, spherical glass particles, irregular shape polymer particles, and fibrous silicon particles are studied. The particle concentration at the test section was measured with the aid of an isokinetic probe in conjunction...

Background: Trauma is one of the most common causes of death in all ages. Considering the prevalence of trauma in the general population, and its costs and complications, it is important to use aiding tools to accelerate the diagnosis in order to act in time. The aim of this study was to evaluate the efficacy of ultrasound in diagnosing nerve and tendon injuries in the upper extremities. Metho...

Microbubbles (MBs) coupled with nanoparticles represent a new class of multifunctional probe for multiscale biomedical imaging and drug delivery. In this study, we describe the development of multifunctional, microscale microbubble probes that are composed of a nitrogen gas core and a biocompatible polymer shell harboring silver nanoparticles (AgNPs). Ultrasound imaging studies show that the pr...
