Adipose tissue lipoprotein lipase (LPL) is a necessary enzyme for storage of VLDL-TG, but whether it is a rate determining step is unknown. To test this hypothesis we included 10 upper-body obese (UBO), 11 lower-body obese (LBO) and 8 lean women. We infused ex-vivo labeled VLDL-¹⁴C-TG and then performed adipose tissue biopsies to understand the relationship between VLDL-TG ...

Many time-based radionuclide techniques, such as glomerular filtration rate measurement (GFR), require prompt intravenous delivery of and accurately measured tracer bolus with minimal residual tracer retention at the injection site. The quality assurance aspects of two antecubital vein, quantitative injection techniques were investigated. A flush bolus ...

Protein losing enteropathy (PLE) is a gastrointestinal disorder that is associated with excessive loss of plasma protein into the gut resulting from abnormal mucosal permeability. The disease is usually caused by inflammation. The loss of protein in PLE is a nonselective process affecting albumin, globulin and transferrin. Abdominal scintigraphy with human serum albumin marked ...

During breathing, the diaphragm and abdominal muscles contract out of phase. However, during other behaviors (including vomiting, postural adjustments, and locomotion) simultaneous contractions are required of the diaphragm and other muscle groups including abdominal muscles. Recent studies in cats using transneuronal tracing techniques showed that in ...

Imaging of tumors with cationic tracers, especially with technetium-99 methoxy isobutyl isonitrile ((99m)Tc-MIBI), revealed high specificity for the diagnosis and follow up of various malignancies. However, these radiopharmaceuticals are of limited value for the diagnosis of malignancies of the abdominal region due to the immediate biliary secretion of the ...

Adipose tissue lipoprotein lipase (LPL) is a necessary enzyme for storage of very-low-density lipoprotein-triglyceride (VLDL-TG), but whether it is a rate-determining step is unknown. To test this hypothesis we included 10 upper-body obese (UBO), 11 lower-body obese (LBO), and 8 lean women. We infused ex vivo-labeled VLDL-(14)C-TG and then performed adipose tissue biopsies to understand the ...

Technetium-99m-labeled leukocyte (WBC) imaging is a valuable screening method for inflammatory bowel disease, especially in children, because of its high rate of sensitivity, low cost, and ease of preparation. A 14-year-old girl is described who had juvenile arthritis and iritis complicated by inflammatory bowel disease. She was examined for recurrent abdominal pain. A Tc-99m ...

The present invention is a biological tracer method for characterizing the movement of a material through a medium, comprising the steps of: introducing a biological tracer comprising a microorganism having ice nucleating activity into a medium; collecting at least one sample of the medium from a point removed from the introduction ...

Development of chemical separations for the transactinides has traditionally been performed with longer-lived tracer activities purchased commercially. With these long-lived tracers, there is always the potential problem that the tracer atoms are not alwa...

Partitioning tracer tests have been used in laboratory and field investigations to quantify the amount of nonaqueous phase liquid (NAPL) within porous media. In these tests multiple chemical tracers are typically injected into flowing groundwater: conservative tracers react minimally with the NAPL, while non-conservative ...

OBJECTIVE Because direct adipose tissue free fatty acid (FFA) storage may contribute to body fat distribution, we measured FFA (palmitate) storage rates and fatty acid (FA) storage enzymes/proteins in omental and abdominal subcutaneous fat. RESEARCH DESIGN AND METHODS Elective surgery patients received a bolus of [1-(14)C]palmitate followed by omental and ...

We report a patient with chronic active hepatitis in whom one of the initial findings was retroperitoneal lymphadenopathy, detected by abdominal ultrasound examination. Extrahepatic presenting findings of chronic active hepatitis may include arthritis, urticaria, pleurisy and pericarditis, while abdominal ...

Velocities of fluids in pipes can be measured by injecting radioactive tracers into the fluid and recording the activity downstream of the injection point. One convenient method of injecting radioactive tracers is by neutron activation of the fluid itself...

''Pitfalls'' in clinical imaging with Indium-111 Leukocytes (In-111 WBC) have been previously discussed. The authors expand these findings by describing 5 further cases of misleading In-111 WBC uptake patterns, 2 cases were of bladder visualization without bladder inflammation; one was due to excretion of WBC's from an infected kidney and another from ...

In animal experiments, studies on the mechanisms involved in drowning were carried out using latex and gold tracers of defined size and concentration. The tracers were detectable by fluorescence microscopy (latex tracers) and by electron microscopy (gold tracers) in the lungs, kidneys and lymph nodes and were ...

Positron emission tomography-computed tomography (PET-CT) fuses uptake of a radiotracer combined with CT images to assess both functional tissue activity and anatomical detail. Since its introduction it ...

Cholescintigraphy with technetium-labeled biliary agents has great value in evaluation of the patient with suspected acute cholecystitis. Visualization of the gall bladder virtually excludes acute cholecystitis and obstruction of the cystic duct. Nonvisualization of the gall bladder, however, is not specific for acute cholecystitis and may also occur in some patients with chronic cholecystitis or ...

An intraoperative beta probe was designed, built, and tested for detection of radio-labeled malignant tissues that has the advantage of being selectively sensitive to beta while insensitive to gamma radiation. Since beta radiation (electrons or positrons) has a short range in tissue, this probe is ideal for detecting tracers in tumors at the surface of the surgical field. This ...

A 66-year-old female patient was admitted to our department with a large tumor of the tongue measuring 10 cm in diameter. The tumor occupied nearly the entire oral cavity and showed exophytic and ulcerative areas. Histological analysis revealed a low grade squamous cell carcinoma (SCC) of the tongue. Bilateral enlarged cervical lymphatic masses were also present. The extent of the tumor ...
