Inosinic acid dehydrogenase was partially purified from sarcoma 180 cells. The concentrations of each reactant, inosine 5’-phosphate, nicotinamide adenine dinucleotide, and K+, altered both the apparent K, and Vmaxvalues for each of the other reactants. Enzymatic activity was inhibited by both products of the reaction, xanthosine S-phosphate and reduced nicotinamide adenine dinucleotide; the in...

This experiment consists of determining the modal properties of a model structure. Many buildings in the practical world can be reasonably approximated by shear structures in which only one translational degree of freedom is taken into account for each floor level. Due to the simple characteristics of a shear structure, it is possible to determine its modal properties, such as the natural frequ...

Objective: To analyze whether for an equal health problem there are gender differences in the drugs used in an adult population attended in the Health Care Centers of the Valencian Community (Spain). Methods: A cross-sectional analytical study was carried out between February-August 1997. The independent variables were: socio-economic parameters, frequency of visits, and selfperceived or diagno...

In the globalized world, good products may not be enough to reach potential clients if creative marketing strategies are not well delineated. Public relations are also important when it comes to capture clients attention, making the first contact between them and companies products while being persuasive enough to trust that the company has the right products to fit their needs. A virtual publi...

Carcinomas in the oral region, like those found in other regions of human body, have differences owing to sex, age, spot of primary origin, etc., in terms of their frequency. Observations of these differences are, therefore, full of significance not only from a clinical point of view as providing an exact diagnostic tool, but also from a pathological standpoint in that it makes clear peculiarit...

A fully automated direct assay of testosterone has been developed for the Ciba Corning ACS:180 immunoassay system. We have evaluated this method and compared specimen results with those from the Diagnostic Products Corp. (DPC) and Medgenix direct assays and an in-house extraction assay. Accuracy of the method was assessed by measuring GC-MS-targeted serum pools. Within-assay im- precision was <...
