Indium Tris-thiocarbamates, *H N M R Spectra Indium tris(thiocarbamates) In(S2CN'Pr2)3 (1), In(SOCN'Pr2)3 (2) and In(S2CNC4H4)3 (3) have been synthesized and characterized. Variable temperature *H NM R spectra of 1 and 2 are reported. The X-ray molecular structures of 1 and 3 are found to be quite similar; the symmetry of the In(S2C)3 unit in 3 is close to point group D 3 with small asymmetry i...

Indium vanadate (InVO4) gas sensors were fabricated by depositing InVO4 nanoribbons aqueous suspension onto ceramic substrates. Their resistances distinctively increased in the detection of ammonia and propylamine, indicating an n-to-p semiconductor transition. This novel phenomenon of the InVO4-based sensor may be ascribed to the surface doping effect: electrons were trapped by H2O and O2 and ...

The outstanding electrical, mechanical and chemical properties of graphene make it attractive for applications in flexible electronics. However, efforts to make transparent conducting films from graphene have been hampered by the lack of efficient methods for the synthesis, transfer and doping of graphene at the scale and quality required for applications. Here, we report the roll-to-roll produ...

  Introduction: Over expression of selected peptide receptors in human tumors has been shown to represent clinically relevant targets for cancer diagnosis and therapy. The aim of this work was to investigate Neuropeptide Y (NPY) as a new radiopharmaceutical for diagnosis of breast cancer. Methods: A neuropeptide Y analogues with Y1 receptor preference and agonistic p...

Studies in the collagen and rabbit models of arthritis have indicated that indium-111 chloride (111InCl3) scintigraphy objectively measures synovial inflammation. Indium-111 chloride scans, with imaging three days after 19 MBq intravenous injection, were performed on 21 patients with definite or classical rheumatoid arthritis (RA), all of whom were functional class II. Standard clinical indices...

Patients who are human immunodeficiency virus (HIV) antibody positive are at increased risk of life threatening infection. Scintigraphic imaging with Ga-67 citrate has been used to identify the presence and site of focal infection. However, focal accumulation of Ga-67 is not specific for infection. A retrospective study was performed to compare the accuracy of Ga-67 citrate and pooled human pol...

The survival of red cells labelled with indium-111 oxine in the circulation was determined. In vivo distribution at equilibrium and sites of deposition at the T50In--that is, the half life of labelled red cells--were quantitated with a scintillation camera and computer assisted image analysis. Although the rate of elution. Of 111In from the red cells was higher than that of chromium-51-disodium...

Carcinoid is a neuroendocrine neoplasm derived from primitive stem cells, occurring most frequently in the alimentary tract. Somatostatin-receptor scintigraphy with indium-111 pentetreotide is a sensitive and noninvasive technique for imaging carcinoid and its metastatic spread. However, nontumoral lesions such as sarcoidosis may also express somatostatin receptors, which may present a diagnost...
