Thin-film solar cells made from earth-abundant, inexpensive, and non-toxic materials are needed to replace the current technologies whose widespread use is limited by their use of scarce, costly, and toxic elements. Tin monosulfide (SnS) is a promising candidate for making absorber layers in scalable, inexpensive, and non-toxic solar cells. SnS has always been observed to be a p-type semiconduc...

Tin-antimony sulfide nanocomposites were prepared via hydrothermal synthesis and a N2 reduction process for use as negative electrode in sodium ion battery. The electrochemical energy storage performance of the battery was analyzed according to tin-antimony composition. optimized sulfides exhibited superior charge/discharge capacity (770 mAh g-1 at current density 100 mA g-1) stable lifespan ch...

UNLABELLED Lymphoscintigraphy allows functional assessment of lymphatic transport and depiction of regional lymph nodes, is fast and nontraumatic and has no known side effects. We retrospectively analyzed lymphoscintigraphic studies to determine their efficacy in the investigation of chyluria, chyloperitoneum and chylothorax. METHODS Twenty-one whole-body lymphoscintigrams using 99mTc-antimon...

An incidental finding of absent splenic uptake of autologous, indium-111-oxine-labeled leukocytes in an immunosuppressed renal transplant recipient was documented to be associated with functional asplenia based on absence of technetium-99m-sulfur colloid clearance by a morphologically normal spleen. The patient had recently suffered an episode of disseminated varicella infection that might have...

We report a case of intrathoracic extramedullary hematopoiesis associated with hemolytic anemia. While the paravertebral localization of the lesions demonstrated on CT and MRI was suspicious of intrathoracic extramedullary hematopoiesis, In-111 chloride and Tc-99m Sn colloid bone marrow scintigraphies showing a bone marrow element of the lesion were useful to confirm the diagnosis.

We present the case of a 40-year-old male with multiple myeloma for whom bone marrow scintigraphy was utilized to help differentiate between active bony myelomatous disease versus treated lesions with compensatory marrow uptake. This case demonstrates technetium (Tc-99m) sulfur colloid imaging as an inexpensive technique to quickly distinguish between active focal bone disease and reactive marrow.

UNLABELLED The purpose of this study was to compare the results of isotope injection the morning of surgery (1-d protocol) with isotope injection the day before surgery (2-d protocol) in patients having sentinel lymph node (SLN) biopsy for breast cancer. METHODS The 1-d (protocol 1) and 2-d (protocol 2) protocols included 514 and 152 patients, respectively, treated contemporaneously by surgeo...

We encountered a case of splenic pseudotumor. It contained a cystic portion, and the solid portion of the mass showed much higher vascularity than the proper spleen on dynamic CT. An accessory spleen was considered most likely, but the differential diagnosis still included malignant lymphoma and metastatic tumor. The diagnosis was obtained by technetium-99m Sn colloid scintigraphy.
