The aim of this study is to investigate whether (111)Indium-labelled recombinant FVIIa (rFVIIa) could be a potential radiopharmaceutical for localization of bleeding sources. DTPA-conjugated rFVIIa was radiolabelled with (111)In chloride. In vitro binding efficiency of (111)In-DTPA-rFVIIa to F1A2-Mab-sepharose was 99% in buffer, while it was 88-82% in serum. The binding efficiency of (111)In-DT...

Surfactant micelles (cetyltrimethylammonium chloride) adsorbed on Au(111) exhibit orientational order dictated by the gold crystal axes. To explain this phenomenon, we take into account the ionic contribution to the dielectric response of the metal. Since the motion of an ion inside the metallic lattice is restricted by its neighbors in an anisotropic way, the total dielectric response of the m...

The myocardial uptake of In-111 antimyosin Fab and Tc-99m pyrophosphate was studied in dogs undergoing coronary artery occlusion for 90 minutes followed by reperfusion. The regional myocardial blood flow was determined by injecting Sc-46 labeled microsphere and was related to the relative concentrations of In-111 antimyosin and Tc-99m pyrophosphate. There was an inverse linear correlation betwe...

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.

In the title compound, C(12)H(14)N(2) (2+)·2Cl(-), the 4,4'-dimethyl-2,2'-bipyridinium cation is essentially planar (r.m.s. deviation for all non-H atoms = 0.004 Å) and is located on a crystallographic inversion centre. The cations and chloride anions lie in planes parallel to (111) and are connected by N-H⋯Cl and C-H⋯Cl hydrogen bonds.

For the diagnosis of cystic fibrosis, we use the "Macroduct Sweat Collection System" (Wescor) to sample sweat, and anion-exchange chromatography to determine its chloride content. The chromatographic system consists of a Whatman Partisil SAX 10-microns column, an isocratic phosphate-buffered mobile phase, and ultraviolet detection at 200 nm. The sweat chloride concentrations of 10 individuals w...

OBJECTIVE To assess the clinical utility of SPECT/ CT in subjects with endocrine and neuroendocrine tumors compared to SPECT alone. MATERIAL AND METHODS 48 subjects (31 women;17 men; mean age 54±11) with clinical suspicion or diagnosis of endocrine and neuroendocrine tumor had 50 SPECT/CT scans (32 Tc-99m MIBI, 5 post treatment I-131, 8 In-111 Pentetreotide, and 5 I-123 MIBG). SPECT alone fin...

OBJECTIVE This study was undertaken to evaluate the efficacy of a new adjuvant protocol with octreotide, alone or in combination with radiotherapy, in radically resected large cell neuroendocrine carcinomas of the lung. METHODS Between 1990 and 2001, a total of 18 consecutive patients affected by large cell neuroendocrine carcinomas of the lung were operated on. Lobectomy and systemic lymphad...
