The groundbreaking discovery1 that graphite could be cleaved into its 2D building block, graphene, has led to similar efforts directed towards other layered 3D solids. In fact, a wide variety of 2D materials have been discovered over the past decade: phosphorene, transition metal dichalcogenides and MXenes (transition metal carbides, nitrides or carbonitrides) to name just a few2,3. Most such 2...

An 8-yr-otd boy with a l-too history of culture-negative fever and anemia underwent gallium, ultrasound, and computed tomography studies as part of the evaluation of a fever of unknown origin. These studies revealed a mobile gallium-avid solid abdominal mass subsequently proven to be an inflammatory pseudotumor of the mesentery, a rare benign mass. This report documents the gallium-avid nature ...

AIM To study the effect of gallium nitrate in the treatment of flare hypercalcemia in rats, bearing mammary tumor with bone metastasis. MATERIALS AND METHODS Female Sprague-Dawley albino rats were used in the study. Animals were divided into 5 groups: normal control; hypercalcemic rats bearing DMBA-induced mammary tumors; flare hypercalcemic animals bearing DMBA-induced mammary tumors (hyperc...

Objective: To evaluate the value of Gallium-67 single-photon emission computed tomography/computed tomography in the diagnosis and monitoring treatment response of malignant otitis externa. Methods: Eight patients underwent 12 Gallium-67 single-photon emission computed tomography/computed tomography scintigraphy for eight suspected malignant otitis externa and were subsequently subjected to vis...

Two topologically different metallamacrocycles--S8 symmetric octanuclear gallium(III) metalladiazamacrocycle and pseudo-D4 symmetric octanuclear gallium(III) metalladiazamacrocycle--could be prepared using two similar heteroditopic bridging ligands having asymmetrical tridentate-bidentate binding residues.

introduction: although pet scanning using f-18[fdg] is considered the superior radiotracer for tumnor imaging, gallium-67 is still in use for some malignancies such as lymphoma and hepatoma. one of the strategies to improve the diagnostic accuracy of gallium is to perform spect which is reported to be more sensitive compared to planar imaging. in this study we compared the sensitivity of spect ...

Phosphate-based glasses (PBGs) are excellent controlled delivery agents for antibacterial ions such as silver and gallium. The aim of this study was to assess the potential utility of novel PBGs combining both gallium and silver for use in periodontal therapy. To this end, an in vitro biofilm model with the putative periodontal pathogen, Porphyromonas gingivalis, and an initial colonizer, Strep...
