BACKGROUND Hepatocellular carcinoma (HCC) is a particularly lethal cancer with few treatment options. Since gallium is known to accumulate specifically in HCC tumors but not in non-tumor liver, we investigated two gallium compounds, gallium nitrate (GaN) and gallium maltolate (GaM), as potential new agents for treating HCC. MATERIALS AND METHODS The anti-proliferative and apoptotic activities...

A mouse model of cystitis caused by uropathogenic Escherichia coli was used to study the distribution of gallium in bladder tissue following oral administration of gallium maltolate during urinary tract infection. The median concentration of gallium in homogenized bladder tissue from infected mice was 1.93 μg/g after daily administration of gallium maltolate for 5 days. Synchrotron X-ray fluore...

that the gallium activity was located near the stomach. After another glass of water was taken, the stomach was imaged again, using the upper three gallium peaks and thus excluding the Tc99m energy. This showed that the gallium activity was no longer present in the stomach (Fig. I). Gallium and Tc-99m were seen on the oscilloscope to enter the small bowel. An image taken 30 min later did not sh...

Yttrium iron garnet (YIG) is a magnetic insulator with record-low damping, allowing spin-wave transport over macroscopic distances. Doping YIG gallium ions greatly reduces the demagnetizing field and introduces perpendicular anisotropy, which leads to an isotropic dispersion that facilitates optics steering. Here, we characterize of gallium-doped (Ga:YIG) thin film using electrical spectroscopy...

The extractabilities of aluminium(III), gallium(III), and indium(III) from hydrochloric acid solutions were investigated using a mixture of two protic ionic liquids, trioctylammonium bis(trifluoromethanesulfonyl)amide ([TOAH][NTf(2)]) and trioctylammonium nitrate ([TOAH][NO(3)]). At a HCl concentration of 4 mol L(-1) or more, gallium(III) was nearly quantitatively extracted and the extractabil...

Gallium is a group IIIa metal that has efficacy in the therapy of malignant disorders such as lymphoma and urothelial tract tumors. Preclinical studies also indicate a role for gallium in autoimmune disorders, suggesting that gallium is able to modulate T-cell immune reactivity. The purpose of this study was to examine the in vitro and in vivo immunomodulatory action of gallium on T-cell functi...

Planar Indium Gallium Arsenide (In0.57Ga0.47As) Gunn diode was fabricated on a semi-insulating indium phosphide substrate with on chip matching circuit to enable the extraction of second harmonic in millimeter and terahertz frequencies. The In0.57Ga0.47As planar Gunn diodes were designed with an active length of 4 lm, channel width of 120 lm and integrated with a novel diamond resonator to supp...

Effect of gallium nitrate on the pharmacokinetics and tissue accumulation of 67Ga was investigated in rats bearing turpentine oil-induced abscess. Gallium nitrate accelerated the blood disappearance of 67Ga, but this effect was less potent than that of ferric nitrate. The accumulation of 67Ga in liver was significantly lowered by gallium nitrate, but no significant decrease of 67Ga accumulation...

Power devices are increasingly important and more complex, often using wide bandgap materials such as Silicon Carbide (SiC) and Gallium Nitride (GaN). The need for high voltage, high power, and fast switching devices operating in harsh environments require accurate design and performance optimization for both device and circuit operation. The best solution is complete integration from process f...

The Gallium Nitride (GaN) Light-Emitting-Diode (LED) bottom refection grating simulation and results are presented. A microstructure GaN bottom grating, either conical holes or cylindrical holes, was calculated and compared with the non-grating (flat) case. A time monitor was also placed just above the top of the LED to measure both time and power output from the top of the LED. Many different ...
