Abdominal ultrasonic scanning was compared to lymphangiography and intravenous urography in 50 patients with testicular cancer. In 25 lymphangiographic stage I patients, the ultrasonic scanning was normal in all cases, too. In 5 out of 25 lymphangiographic stage II patients, the ultrasonic examination demonstrated a wider extension of the retroperitoneal metastases than combined lymphangiography and urography. The ultrasonically demonstrated masses were proven to contain malignant cells through an ultrasonically-guided fine-needle puncture in all 5 cases. Sufficient planning of the radiation ports would not have been possible in these patients without the additional ultrasonic scanning. In monitoring of the therapeutic response, ultrasonic scanning was found superior to lymphangiography.

Polysaccharides from the dried tuber of Typhonium giganteum Engl. (TGEPs) were obtained by utilizing ultrasonic-assisted extraction (UAE) as the extraction method. The determination of optimal process parameters for the UAE of TGEPs (TGEP-U) was accomplished through the application of response surface methodology (RSM).

Objective: This study investigated the associations among endodontic instruments, ultrasonic tips and various final irrigation protocols for removing intracanal and intratubular biofilms in long oval canals.
Methodology: One hundred mandibular premolars inoculated with Enterococcus faecalis were divided into two groups: the control group (CG: n = 10), which received no treatment; and the test groups (n = 30), which included saline (SS), sodium hypochlorite (2.5% NaOCl) and chlorhexidine (2% CHX).

The post-harvest management of fruit is crucial to preventing its decay and loss. Generally, edible coatings are applied to fruit to avoid decay and microbial contamination. We have used ultrasonication to synthesize TiO and residue-derived biosilica embedded in gum arabic nanocomposite.

This study investigates the effect of ultrasonic-assisted preparation on the structural and physicochemical properties of water caltrop starch-palmitic acid complexes as a function of ultrasound intensity and treatment time. All samples exhibited the characteristic birefringence of starch-lipid complexes under the polarized microscope, and flake-like and irregular structure under scanning electron microscope (SEM), indicating the formation of complexes through ultrasonic-assisted preparation. X-ray diffraction pattern further confirmed the transition from the original A-type structure for native starch to V-type structure for starch-lipid complexes, and the relative crystallinity of starch-lipid complexes increased as the ultrasound intensity and treatment time increased.

Adding value to food by-products, such as pumpkin seeds, is an important strategy for the complete utilization of plant foods and advancing sustainability goals. This study aimed to maximize the production of bioactive peptides from pumpkin seed protein (PSP) by combining ultrasonic (US) pretreatment (40 kHz, 23.8 W/L) with enzymatic hydrolysis.
