Data from an acoustic Doppler current profiler (ADCP), a wave-gauge, met-ocean buoy and model results provide new insights into the wave regime in partially sheltered upwelling-driven bay, Ría de Vigo (NW Iberia), adjacent continental shelf June 2013 to August 2014. Swell on NW-Iberian comes mainly NW directions, while wind sea under upwelling conditions, SW downwelling conditions. As ria is pr...

Rich Internet Applications (RIAs) have become a common platform for Web developments. Its adoption has been accelerated thanks to different factors, among others, the appearance of patterns for typical RIA behaviors and the extension of different Model Driven Web Engineering methodologies to introduce RIA concepts. The real fact is that more and more developers are switching to RIA technologies...

The performance of enzyme immunoassay (EIA) and radioimmunoassay (RIA) in the quantitative analysis of ecdysteroids was compared. The EIA was found to be at least equivalent to the RIA with respect to analytical range and sensitivity and to be more comfortable with respect to safety and time saving. When biological samples were analyzed by both assays a good correlation (r = 0.83) was found. Si...

A recently described hemagglutination test for hepatitis B antigen (HBsAg) using turkey erythrocytes coated with horse antibody to HBsAg purified by affinity column chromatography was evaluated on a comparative basis with 100 HBsAg-positive and -negative serum samples. The turkey erythrocyte hemagglutination test (TEHA) was found to be less sensitive than radioimmunoassay (RIA) but gave far bet...

A new procedure for measuring cyclosporine in plasma has been introduced by Abbott Laboratories, involving their TDx instrumentation and fluorescence polarization immunoassay. Radioimmunoassay (RIA) and high-performance liquid chromatography are currently the conventional methods for measuring cyclosporine in plasma and whole blood. In an effort to find a method that will decrease the radioacti...

The effect of two concentrations of prednisolone on synthesis of prostaglandin E2 (PGE2) by 40 rectal biopsies in organ culture was investigated using both laminar flow bioassay and radioimmunoassay (RIA). Prednisolone (concentration 8.33 x 10(-7)M) reduced mean synthesis of PGE2 to 36.4% of control values (measured by bioassay) or 26.2% of control values (measured by RIA). With prednisolone (c...

To date, many of the current criteria for diagnosis of somatotropin (growth hormone, GH) deficiency have been based upon measurement of this hormone by competitive radioimmunoassay (RIA) with use of polyclonal antibodies. In recent years, however, the development of hybridoma technology has led to the generation of various monoclonal antibodies (Mabs) to GH with different affinities and epitope...

An indirect solid phase radioimmunoassay (RIA) was developed for typing antibody to herpes simplex virus (HSV) types 1 and 2 (HSV-1 and HSV-2) in human sera. The test is based upon absorption of sera with uninfected, HSV-1-infected cells and testing for residual antibody. The high sensitivity of the RIA method for detecting HSV antibody permits examination of sera at high dilutions, and thus re...

BACKGROUND High concentrations of estrone sulfate (EIS) are present in serum of pre- and postmenopausal women. Most assays for this estrogen conjugate involve enzyme hydrolysis and chromatographic purification prior to RIA. We have compared concentrations of serum EIS in postmenopausal women measured by direct RIA or GC-MS/MS methods. PATIENTS AND METHODS We analysed serum EIS concentrations ...
