The possibility of reducing the pesticide load on agrocenosis without losing economic and biological effectiveness fungicides is considered. results a two-year experiment comparing single application fungicide Elatus® Ria, EC (active ingredient: 83.33 g/l Solatenol®, 66.67 cyproconazole, 208.33 propiconazole) with base Alto Super, 250 propiconazole, 80 cyproconazole) in winter wheat crops Zhemc...

BACKGROUND Approximately 2 million patients in the United States annually undergo total joint arthroplasty with reaming and placement of intramedullary nails, resulting in extravasation of bone marrow and fat into the circulatory system and potentially causing fat embolism syndrome. Acute and chronic changes in mental status documented after these procedures may be related to embolic events. Th...

Chapter 5 looks at a study within the OECD of the application of RIA in the field of the regulation of corporate governance. Noting that the requirement to undertake RIA is an established part of the regulatory systems of OECD members, this chapter examines examples of the application of RIA by financial services regulators to strengthen their evidence-based policy-making. It draws on examples ...

A radioimmunoassay (RIA) of progesterone in urine is described. After the addition of labelled progesterone, morning urine was extracted with n-hexane adn the residue was either directly subjected to RIA, or chromatographed on celite prior to RIA. The progesterone from celite chromatography was radiochemically pure. RIA after chromatography was therefore considered valid. The non-chromatographe...

Starting from the development of VR and WEB technologies, in this article, we analyze the characters and the development foregrounds of the 3D virtual community based on the WEBVR (Web Virtual Reality) technology, and introduce the characters of the RIA (Rich Internet Application) technology system. And we put forward the technical frame of the 3D virtual community based on WEBVR and RIA, and i...

Receptors for the Fc portion of immunoglobulin (Ig)G (Fc gamma R) mediate phagocytosis of IgG-opsonized particles by a process that can be divided into four major steps: receptor-ligand binding, pseudopod extension, internalization, and lysosomal fusion. We have expressed single classes of Fc gamma R in COS fibroblasts to examine the structural determinants necessary to complete the four steps ...

OBJECTIVE To test the clinical usefulness of sensitive commercial immunoassays for determination of low 17beta-estradiol concentrations in children. METHODS The lower limit of detection and clinical usefulness (functional sensitivity) of three commercial estradiol immunoassays were validated by use of 500 sera from prepubertal and pubertal children and 55 pooled sera. The three immunoassays c...

A radioimmunoassay (RIA) procedure is described for measuring antibodies to alphaviruses in human and other mammalian sera. The test employed protein Abearing Staphylococcus aureus as a solid-phase immunoadsorbent for (3)H-labeled viruses complexed with immunoglobulin G. Using antibodies produced in humans and guinea pigs, the RIA procedure clearly differentiated among antibodies to Venezuelan,...

LY309887, a reduced analogue of folic acid, is a potent inhibitor of glycinamide ribonucleotide formyltransferase and possesses a broad spectrum of antitumor activity. During preclinical studies using supplementation with oral folic acid, this second-generation inhibitor displayed both the desired safety profile and the pharmacology to warrant clinical investigation. A sensitive analytical meth...
