Chemokines are a group of structurally related peptides that promote the directed migration of leukocytes in tissue. Mechanisms controlling the retention of chemokines in tissue are not well understood. In this study we present evidence that two different mechanisms control the persistence of the CXC chemokine, IL-8, in lungs and skin. (125)I-labeled IL-8 was injected into the airspaces of the ...
With the assistance of molecular docking and 3D-QSAR models established previously, structurally identical (18)F- and (125)I-labeled benzyloxybenzene derivatives were designed to achieve the early detection of Aβ plaques by PET/SPECT imaging. In competition binding assay, ligands 7a and 12a displayed high binding affinities to Aβ42 aggregates with Ki values of 19.5 nM and 23.9 nM, respectively....
UNLABELLED A33, a monoclonal antibody that targets colon carcinomas, was labeled with (125)I or (131)I and the relative therapeutic efficacy of the 2 radiolabeled species was compared in a human colon cancer xenograft system. METHODS Nude mice bearing human SW1222 colon carcinoma xenografts were administered escalating activities of (125)I-A33 (9.25-148 MBq) or (131)I-A33 (0.925-18.5 MBq), (1...
Some quantitative aspects of the labelling of proteins with 125 I by the iodine monochloride method.
The labelling of proteins by the iodine monochloride method was studied by using a mathematical model. The equations used were primarily derived from the mass law equation of the isotopic exchange reaction between [(125)I]iodide and iodine monochloride. For convenient application, all equations were programmed into a computing desk-top calculator. To support the validity of the theoretical mode...
BACKGROUND Iodine 125 ((125)I) seed irradiation is an effective non-surgical treatment for unresectable hepatocellular carcinoma (HCC) patients. However, the safety and tolerability of (125)I seed sequential irradiation therapy remain unclear, there is no unified standard of brachytherapy radiation dose, and further study on the basic radiobiology of continuous rate irradiation is necessary. ...
The uptake of (125)I albumin microaggregates (U-(125)I-AMA) from portal blood, during a single passage through the hepatic reticuloendothelial system, has been found to be generally decreased in cirrhosis. To investigate if a similar phenomenon occurs for the colloid flowing through the hepatic artery, the U-(125)I-AMA was first calculated in normal dogs after injection of a mixture of (51)Cr r...
Islet amyloid deposition composed of amylin aggregates is regarded as one of the hallmarks of type 2 diabetes mellitus (T2DM). For the diagnosis of T2DM, several nuclear medical imaging probes have been developed. However, there have been no reports regarding the development of imaging probes targeting amylin. In this report, we investigated the feasibility of amylin imaging using [(125)I]IPBF ...
این پژوهش با الهام گرفتن از نتایج یک طرح مطالعاتی کاربردی، رویکرد سلسلهمراتبی جهت پیگیری فرایند توسعه تأمینکنندگان و حمایت تصمیمات موجود در هر مراحل آن ارائه میکند. ابتدا، زمینههای تأمین نیازمند سپس واجد شرایط هریک زمینهها به کمک تصمیمگیری چندشاخصه بهترین-بدترین مشخص میگردند. معیارهای شناسایی نیز مرور مطالعات پیشین بهرهگیری نظرات خبرگان حوزهی خرید استخراجشدهاند. درنهایت، مدل ریاضی ...
Radiation myelitis is the most serious complication in clinical radiotherapy for spinal metastases. We previously showed that (125)I brachytherapy induced apoptosis of spinal cord neurons accompanied by autophagy. In this study, we further investigated the mechanism by which (125)I radiation triggered autophagy in neural cells. We found that autophagy induced by (125)I radiation was involved in...
The kinetics for mesangial uptake and transport of radiolabeled aggregated human immunoglobulin (Ig)G (AHIgG(125)I) deviated markedly from normal in male Sprague-Dawley rats with ureteral obstruction. Four experimental groups, each containing 25 rats, were used: (a) bilateral ureteral ligation (BUL) with release of one ureter 24 h later; (b) unilateral ureteral ligation with release 24 h later ...
