BACKGROUND Any sentinel lymph node that receives lymph drainage directly from a primary melanoma site, regardless of its location, may contain metastatic disease. This is true even if the sentinel node does not lie in a recognized node field. Interval (in-transit) nodes that lie along the course of a lymphatic vessel between a primary melanoma site and a recognized node field are sometimes seen...

Lymphoscintigraphy was used to measure lymphatic function at rest and during exercise in breast cancer survivors with lymphedema (BCRL, n = 10), breast cancer survivors (BC, n = 10), and controls (Cont, n = 10). After injection of (99m)Tc-antimony colloid to the hands, subjects rested or performed 12 repeated sets of arm cranking for 2.5 min at 0.6 W/kg followed by 2.5 min of rest. One-minute s...

A new chemical deposition method has been developed to prepare photoconducting n-Sb2S3 thin polycrystalline films. The solution composition of the deposition bath was 0.025M potassium antimonyl tartarate, 0.4M triethanolamine, 0.025M thioacetamide, and 5 • 10-7M silicotungstic acid (STA), respectively. The as-deposited and the annealed films were characterized through x-ray diffraction, neutron...

Janus colloids propelled by light, e.g., thermophoretic particles, offer promising prospects as artificial microswimmers. However, their swimming behavior and its dependence on fluid properties and fluid-colloid interactions remain poorly understood. Here, we investigate the behavior of a thermophoretic Janus colloid in its own temperature gradient using numerical simulations. The dissipative p...

The antimony-iron sulfide system in general does not produce alloys below 540 °C from traditional solid-state methods. However, single source precursors have been known to unexpected products that arise kinetically trapped polymorphs. In this paper, we test the efficacy of approach toward Fe-Sb-S system. Antimony and iron diethyldithiocarbamate complexes form Sb[S2CN(Et2)]3 (1) Fe[S2CN(Et2)]3 (...

An 18 year old woman with beta thalassaemia/haemoglobin E developed a large pelvic tumour resulting in bilateral obstructive uropathy. Technetium-99m sulphur colloid marrow image, computed tomographic scan of the abdomen and needle biopsy of the mass confirmed the diagnosis of extramedullary haematopoiesis. Although radiation is the treatment of choice for decompression, the mass in this patien...

Three groups of 24 C57BL/6J black mice were studied. One group was implanted with B16 malignant melanoma, another was implanted with mammary adenocarcinoma, and the third was not given tumor implants. After 14 to 17 days, the mice were given injections i.v. of technetium-99m sulfur colloid and killed 30 min later. Organs were weighed, and radioactivity was counted. The ratios of specific radioa...

Local regional recurrence of renal cell cancer post-nephrectomy most often occurs within three years after surgery. Post-nephrectomy, many processes may mimic RCC recurrence. We present the case of a 75 year-old Caucasian male patient with a mass in his renal fossa post-nephrectomy for renal cell cancer, suggesting local recurrence. Use of the technetium-99m sulfur colloid scan showed that the ...
