Patients with primary cutaneous melanoma underwent sentinel node (SN) mapping and biopsy at 25 facilities in Japan by the combination of radiocolloid with gamma probe and dye. Technetium-99m ((99m)Tc)-tin colloid, (99m)Tc-phytate, 2% patent blue violet (PBV) and 0.4% indigo carmine were used as tracers. In some hospitals, 0.5% fluorescent indocyanine green, which allows visualization of the SN ...
UNLABELLED A wide range of radiolabeled test meals have been used for gastric emptying scintigraphy. The purpose of this study was to test whether (99m)Tc-sulfur colloid-labeled liquid egg white is as stable as 2 fresh whole eggs labeled with (99m)Tc-sulfur colloid and whether the cooking method is important. METHODS Whole eggs and liquid egg white were mixed with (99m)Tc-sulfur colloid and c...
A 62-year-old patient presented with flatulence, abdominal distension and other symptoms of ileus. Roentgenographic finding found compression on duodenum. Blood pool scintigraphy ((99m)Tc erythrocytes) showed aortal aneurysm, while simultaneous gastric emptying study with liquid meal ((99m)Tc-S-colloid) showed dislocation of duodenum and compression from abdominal aortal aneurysm.
when tc-99m-sulfur colloid was introduced as an ideal liver-spleen agent in nuclear medicine, many other types of colloids followed by different manufacturers. they hoped to find a suitable colloidal agent, contrary to sulfur colloid, which is easy to use, and less sensitive to the low contamination of aluminum ions. one of this type of colloid agents, is tc-99-tin-colloid which is prepared by ...

Gastrointestinal bleeding scintigraphy performed with (99m)Tc-labeled autologous erythrocytes or historically with (99m)Tc-sulfur colloid has been a clinically useful tool since the 1970s. This article reviews the history of the techniques, the different methods of radiolabeling erythrocytes, the procedure, useful indications, diagnostic accuracy, the use of SPECT/CT and CT angiography to evalu...
BACKGROUND The new trend in diagnosis of the lymph node is sentinel node biopsy. This method has become increasingly accepted as a minimally invasive alternative to routine axillary dissection. Although the results of numerous studies have shown that sentinel node biopsy can accurately determine the axillary nodal status, the identification rates and false-negative rates have been variable. The...
Observation of high-temperature superconductivity in compressed sulfur hydrides has generated an irresistible wave of searches for new hydrogen-containing superconductors. We herein report the prediction of high-T_{c} superconductivity in tellurium hydrides stabilized at megabar pressures identified by first-principles calculations in combination with a swarm structure search. Although telluriu...
This work aimed to investigate the effect of lipoic acid (LA) on sulfane sulfur (S*) level, infiltration of neutrophils and vascular permeability in a model of zymosan-induced peritonitis. The study showed that lipoic acid increased the sulfane sulfur level. Also, it decreased count of neutrophils and inhibition of intensity of early vascular permeability compared to the control group. These st...
Select meteoritic classes possess mass-independent sulfur isotopic compositions in sulfide and organic phases. Photochemistry in the solar nebula has been attributed as a source of these anomalies. Hydrogen sulfide (H2S) is the most abundant gas-phase species in the solar nebula, and hence, photodissociation of H2S by solar vacuum UV (VUV) photons (especially by Lyman-α radiation) is a relevant...
