E-cadherin, a member of the cadherin family, plays a major role in cell-cell adhesion of normal epithelium. Recent studies have shown that reduction or loss of E-cadherin expression in carcinomas have some relationship with their clinicopathological manifestation including invasion and metastasis. In the present study, we have established cell clones with different E-cadherin expression from hu...

Background. Topical diagnosis of primary hyperparathyroidism (PHPT) remains an urgent problem due to the high incidence persistence and recurrence after surgical treatment. At preoperative stage, a search for parathyroid hormone hyperproduction source is performed using instrumental methods: ultrasound, scintigraphy glands (PTG) multislice computed tomography (MSCT). The cause PHPT parathyroide...

Purpose: To demonstrate a rare clinical case of early recurrence verified primary genital lymphoma and the possibility 99mTc-1-Thio-D-glucose (99mTc-TG) SPECT/CT using to brain metastasis diagnosis. Material methods: A patient with diagnosis diffuse large B-cell underwent magnetic resonance imaging (MRI) assess extent disease. Post-treatment follow-up included 18F-FDG PET/CT. diagnose metastasi...

BACKGROUND Studies have shown that antibodies targeting the intracellular (ICD) or extracellular domains (ECD) of human epidermal growth factor receptor 2 (HER2) are equivalent when traditional methods are used. We describe a new method to quantify ICD and ECD expression separately and assess the prognostic value of domain-specific HER2 results in patients who received adjuvant trastuzumab ther...

A radio frequency-free electromagnetostatic (EMS) cell devised for electron-capture dissociation (ECD) of ions has been retrofitted into the collision-induced dissociation (CID) section of a triple quadrupole mass spectrometer to enable recording of ECD product-ion mass spectra and simultaneous recording of ECD-CID product-ion mass spectra. This modified instrument can be used to produce easily...

This first clinical prospective study was conducted to use of technetium-99m immunoglobulin G (99mTc-IgG) as compared with autologous 99mTc-red blood cells (RBC) in gated blood pool ventriculography. We studied 12 patients who referred to us for a possible diagnosis of liver hemangioma or infection. Six patients underwent gated planar blood pool (GPBP) acquisition using 99mTc-RBC and 6 GPBP acq...

BACKGROUND Phosphatidylserine (PS) is a phospholipid normally located in the inner leaflet of the cell membrane. PS is translocated from the inner to the outer leaflet of the plasma membrane during the early stages of apoptosis and in necrosis. In cell and animal studies, reversible PS externalisation to the outer membrane leaflet has been observed in viable cells. Hence, PS markers have been p...

99mTc radiopharmaceuticals play an important role in widespread applications of nuclear medicine. When 99mTc radiopharmaceuticals first came into use, major efforts were directed toward the development of 99mTc radiopharmaceuticals for bone imaging and for the excretory functions of the liver and kidneys. In the past 20 years, a significant advance has been made in technetium chemistry, which p...

BACKGROUND Little is known about the incidence and risk factors of early consciousness disorder (ECD) in patients with acute ischemic stroke, or about how ECD may affect complications and outcomes. METHODS Patients admitted to our hospital within 24 h of onset of acute ischemic stroke were consecutively enrolled. ECD was evaluated clinically and using the Glasgow coma scale. Multivariate anal...

OBJECTIVES To validate 99mTc-labeled arginylglycylaspartic acid (99mTc-3PRGD2) scintigraphy as a means to image synovial neoangiogenesis in joints afflicted by rheumatoid arthritis and to investigate its potential in the early detection and management of rheumatoid arthritis. METHODS Rheumatoid arthritis and osteoarthritis were generated in Sprague Dawley rats by type II collagen immunization...
