BACKGROUND Diagnostic and therapeutic strategies for lower-limb lymphedema have not yet been established. The purpose of this study was to estimate the lymphodynamic condition and therapeutic efficacy of lymphovenous anastomosis (LVA) in lower-limb lymphedema patients using 2-phase (99m)Tc-phytate lymphoscintigraphy with single-photon emission computed tomography-computed tomography (SPECT-CT)....
Soybean [Glycine max (L.) Merr.] seed phosphorus is stored primarily as phytic acid, a form in which it is unavailable to monogastric mammals and birds. Because of the nutritional and environmental problems caused by phytic acid, development of cultivars with low phytic acid (lpa) mutations has become an important objective in many soybean breeding programs. Information about the inheritance of...
Pyrroloquinoline quinone (PQQ), an essential nutrient, antioxidant, redox modulator and nerve growth factor found in a class of enzymes called quinoproteins, was labeled with 99mTc by using stannous fluoride (SnF2) method. Radiolabeling qualification, quality control and characterization of 99mTc-PQQ and its biodistribution studies in mice were performed and discussed. Effects of pH values, tem...
OBJECTIVE To investigate the value of integrin αvβ3 targeted imaging with 99mTc-HYNIC-PEG4-E[PEG4-c(RGDfk)]2 (99mTc-3P-RGD2) as a radiotracer in dectecting osteolytic bone metastases. METHODS This is a retrospective study involving a cohort of 69 consecutive patients including 59 with lung cancer and 10 with other cancers. Patients were required to receive whole body scan (WBS) and regional S...
PURPOSE This study aimed to explore the diagnostic performance of single photon emission computed tomography / computerized tomography (SPECT/CT) using a new radiotracer 99mTc-RGD-BBN for breast malignant tumor compared with 99mTc-3P4-RGD2. METHODS 6 female patients with breast malignant tumors diagnosed by fine needle aspiration cytology biopsy (FNAB) who were scheduled to undergo surgery we...
UNLABELLED The constant-volume urinary bladder model in the standard MIRD Pamphlet No. 5 (Revised) phantom has recognized limitations. Various investigators have developed detailed models incorporating more physiologically realistic features, such as expanding bladder contents and residual volume, and variable urinary input rate, initial volume and first void time. We have reviewed these publis...
UNLABELLED SPECT using 99mTc-hexamethyl propyleneamine oxime (HMPAO) mainly reflects regional cerebral blood flow, however metabolic abnormalities also affect the retention of 99mTc-HMPAO. METHODS To rule out any flow factor, a test-tube model was used to evaluate the effects of metabolic alterations both on intracellular trapping of 99mTc-HMPAO and on extracellular glutamate and lactate dehy...
A 99mTc labeled tropane derivative, [99mTc] TRODAT-1 (2beta-((N,N'-bis(2-mercaptoethyl) ethylene diamino)methyl), 3beta-(4-chlorophenyl) tropane), is a potential dopamine transporter (DAT) imaging agent for the central nervous system. To better understand the binding localization of [99mTc] TRODAT-1 both in the brain and the body, whole-body macroautoradiography (WBAR) was used in this study. T...
introduction phytic acid is a main compound in all plant seeds and contains 60 to 70% of total phosphorus in plant. monogastric animals cannot use phytatephosphorus because of low phytase activity in their digestive tract. thus in addition to unabsorbed mineral phosphorus, phytate phosphorus in fecal ofmonogastric animals may affect water and environment pollution. it is suggested to use of phy...
99MTechnetium-labeled low density lipoprotein (99MTc-labeled LDL) was developed to detect atherosclerosis by external imaging with the gamma scintillation camera (Lees, et al. J. Nucl. Med. 1985. 26: 1056-1062; Lees, et al. Arteriosclerosis. 1988. 8: 461-470). The present study examined high affinity LDL receptor recognition and intracellular sequestration of 99MTc-labeled LDL by fibroblasts. T...
