Accuracy of power mode transcranial Doppler in the diagnosis of brain death
(Elsevier (Singapore) Pte Ltd, 2015)
© 2014.Background: The diagnosis of brain death (BD) is complex. For this reason, we aimed to evaluate the accuracy of power mode transcranial Doppler (PMD-TCD) in diagnosing BD. Patients and methods: Patients admitted to ...
Influence of ultrasound irradiation on the adsorption of bovine serum albumin on copper
(SpringerDordrechtHolanda, 2007)
The influence of external ultrasound on the histologic architecture of the organic capsule around smooth silicone implants: Experimental study in rats
(Springer, 2008-05-01)
Background Capsular contracture is the main complication related to breast silicone implants, and its prevention remains a medical challenge. The authors present experimental research examining the effect of external ...

High intensity ultrasound assisted decaffeination process of coffee beans in aqueous medium
(2018-12-01)
The purpose of this study was to determine the influence of ultrasound intensity, pulse and temperature on extraction of caffeine, from Arabica coffee beans using water as solvent, and ultrasound frequency of 24 kHz. A ...
Ultrasound guidance is not necessary during easy embryo transfers
(Kluwer Academic/plenum Publ, 2004-12-01)
Purpose: To determine whether the use of ultrasound (US) to guide embryo transfer (ET) in a population previously defined as likely to have easy transfer would change the implantation and pregnancy rates in an ICSI ...
Behavior of Bi2S3 under ultrasound irradiation for Rhodamine B dye degradation
(2021-12-16)
In this study, we have demonstrated that Bi2S3 semiconductor under ultrasound behaves as a piezoelectric material, facilitating the transfer of electrons and holes, thus enabling the formation of oxidizing agents. In the ...
Wrist ultrasound analysis of patients with early rheumatoid arthritis
(Associação Brasileira de Divulgação Científica, 2011)
In the present study, we evaluated 42 wrists using the semi-quantitative scales power Doppler ultrasound (PDUS) and gray scale ultrasound (GSUS) with scores ranging from 0 to 3 and correlated the results with clinical, ...
