Intramedullary nail fixation is the treatment of choice for impending and pathologic fractures secondary to metastatic cancer; however, this procedure has been shown to cause systemic embolization of intramedullary contents. This article reports the use of the reamer-irrigator-aspirator (RIA) (Synthes, Paoli, Pennsylvania) instead of a standard femoral reamer to decrease tumor intravasation dur...
BACKGROUND/AIMS This study was designed to investigate the expression and function of gap junction protein connexin 45 (Cx45) in renal interlobar artery (RIA) of spontaneously hypertensive rats (SHR), and the association between hypertension and enhanced vasoconstrictive response in SHR. METHODS Western blot analysis and pressure myography were used to examine the differences in expression an...
Radioactive immunoassay (RIA) is a traditional serum hormone assay method, but the application of the method in reproductive studies is limited by the associated radioactivity. The aim of present study was to evaluate the reliability of RIA and to compare its canine serum progesterone concentration determination accuracy to that of the electric chemiluminescence immunoassay (ECLI). In vivo matu...
The measurement of both immune complex-bound and free unbound tumor-associated antigen was evaluated independently on a panel of sera from colon cancer patients by radioimmunoassay (RIA). A monoclonal antibody (mAb 46.3) raised against secreted antigens from human colon cancer cells in vitro was utilized in the RIA. When circulating immune complexes alone were analyzed, the data demonstrated th...
The aims of the present study were to determine (i) the long-term immunogenicity and the decay rate of hepatitis B virus (HBV) surface antibody (anti-HBs) from universal hepatitis B vaccination at infancy for a healthy population in an area of hyperendemicity and (ii) whether the anti-HBs levels measured by enzyme immunoassay (EIA) were closely correlated with those assayed by radioimmunoassay ...
A monoclonal radioimmunoassay (RIA) was developed for detection of dengue virus in infected cell culture fluids and blood samples from dengue patients. Antibodies used to construct the RIA were selected on the basis of high binding avidity, the demonstration of synergism in competitive binding assays and empirical trials with different antibody combinations. Optimal binding of all four dengue v...
Results obtained by competitive protein binding assay (PBA) and a solid-phase radioimmunoassay (RIA) for cortisol were compared in 157 samples from 100 psychiatric patients given a dexamethasone suppression test (DST). Cortisol levels in plasma samples obtained at 8:00 a.m. or 4:00 p.m. the day following 1.0 mg dexamethasone orally at bedtime ranged from 0 to 30 micrograms/dl and correlated clo...
