Intratumoral injection of ultrasonically prepared emulsions of the synthetic glycolipid methly 6-O-(2-tetradecyl-3-hydroxyoctadecanoyl)-alpha-D-glucopyranoside (designated C39) induced complete regression of transplants of a syngeneic murine fibrosarcoma in most of the treated animals as did 6,6'-di-O(2-tetradecyl-3-hydroxyoctadecanoyl)-alpha,alpha,-trehalose (designated C76) in a previous stud...

Thirty-five rabbit eyes were implanted subchoroidally with Greene's hamster melanoma. When the tumours reached a base diameter of 5 mm, they were treated with ultrasonically induced hyperthermia with a range of temperatures and exposure durations (43-67 degrees C and 75 s to 60 min). Of the 23 treated eyes examined two months after treatment eight showed complete regression of the tumour. Seven...

Ultrasonically-assisted bone cutting with high precision has manyadvantagesfororthopedic surgeries. However, irregular crack propagation, large fractured chips, and surface damagemay occurduring the processdue to brittleness anisotropy of cortical bone. These can be minimized by optimizing operating parameters tool; frequency, amplitude, speed, depth, temperature, inconsideration toughening mec...

Dense machinable α-SiAlON/BN composites were fabricated by hot-pressing using turbostratic boron nitride (tBN) obtained from nitridation of melamine diborate. The tBN was added to the starting powders, or introduced as a coating that formed in situ on α-Si3N4 carrier powders during nitridation, and was subsequently converted to hexagonal boron nitride (hBN) during hot pressing by solution repre...

The self-assembly of uniform single-crystalline microrods of organic dye Sudan II (1-(2,4- dimethylphenyl-azo)-2-naphthol) in solution was achieved by reprecipitation with the assistance of amphiphilic block copolymer Pluronic F127. It was found that the formation of F127 micelles was favorable for the production of uniform Sudan II microrods whereas individual F127 molecules favored the format...

AIM The ultrasonically induced effect of a tumor accumulative derivative of rose bengal (RB) on isolated tumor cells was investigated to clarify whether the RB derivative (RBD) maintains the sonosensitizing ability of RB. MATERIALS AND METHODS Sarcoma 180 cells were suspended in air-saturated phosphate-buffered saline and were exposed to ultrasound in standing wave mode for up to 60 s in the ...

The reprecipitation mechanisms and kinetics of γ' particles during cooling from supersolvus and subsolvus temperatures were studied in AD730(TM) Ni-based superalloy using Differential Thermal Analysis (DTA). The evolution in the morphology and distribution of reprecipitated γ' particles was investigated using Field Emission Gun Scanning Electron Microscopy (FEG-SEM). Depending on the cooling ra...
