UNLABELLED Antibodies accumulate nonspecifically in infectious foci due to the locally increased vascular permeability. This study describes a method of infection imaging in which 99mTc-DTPA (diethylenetriaminepentaacetic acid) is trapped at the target by a previously administered anti-DTPA monoclonal antibody. DTIn1. METHODS Rats with Staphylococcus aureus-infected calf muscle were injected ...

EECD is a non-Langerhans histiocytosis first described by Chester as “lipoidgranulomatose” in 1930.2 By 2010, only 350 additional cases had been added to the literature.3 Patients with ECD typically develop characteristic multifocal osteosclerotic lesions of long bones and may also develop extraskeletal histiocytic infiltrates of other sites including pituitary, orbit, retroperitoneum, kidneys,...

Bone scintigraphy with 99mTc diphosphonates may exhibit extraosseous lesions in addition to metastatic lesions. Multiple factors can affect extraosseous 99mTc methylene diphosphonate (MDP) uptake. Similar uptake pattern of 99mTc MDP and fluorine-18 fluorodeoxyglucose (18F FDG) in hepatic metastasis was not already notified. In our case, initial tumor necrosis and subsequent intracellular calcif...

OBJECTIVE Vincristine has been widely used in various chemotherapeutic protocols in oncology. The purpose of this study was to evaluate the effect of vincristine on the biodistribution of 99mTc-DMSA, 99mTc-GHA, and 99mTc-DTPA in Balb/c female mice. METHODS Vincristine (0.03 mg, 0.3 mL) was injected into female isogenic Balb/c mice (n = 15), in 3 doses over an interval of 96 h. The 99mTc-DMSA,...

The use of radiolabeled antibiotics as diagnostic agents is an emerging area of medical research. Vibramycin is a semisynthetic antibiotic of the tetracycline family prescribed to treat a variety of infections. We present in this study a new technetium-99m labeled vibramycin radiopharmaceutical using SnCl2.2H2O as a reducing agent. The stability of 99mTc-vibramycin was evaluated in human serum ...

OBJECTIVE Stimulation in early childhood can alleviate adverse effects of poverty. In a community-randomised trial, we implemented 2 home-based interventions, each serving as an attention control for the other. One group received an integrated household intervention package (IHIP), whereas the other group received an early child development (ECD) intervention. The primary objective of the study...

Successful electron capture dissociation (ECD) Fourier transform ion cyclotron resonance mass spectrometry (FT-ICR MS) applications to peptide and protein structural analysis have been enabled by constant progress in implementation of improved electron injection techniques. The rate of ECD product ion formation has been increased to match the liquid chromatography and capillary electrophoresis ...

With the shortage of standard criteria donor (SCD) kidneys, efficient expanded criteria donor (ECD) kidney utilization has become more vital. We investigated the effects of the ECD label on kidney recovery, utilization and outcomes. Using data from the Scientific Registry of Transplant Recipients from November 2002 to May 2010, we determined recovery and transplant rates, and modeled discard ri...

Amplification or over-expression of an activated Cdc42-associated kinase 1 (ACK1) gene is common in breast, lung and ovarian cancers. However, little is known about the role of ACK1 in gastric tumorigenesis. Here, we found that DNA copy numbers of the ACK1 gene and its mRNA expression levels were significantly increased in gastric cancer (GC) compared to normal gastric tissues. Additionally, si...
