Abstract:
A method is provided for reducing the incidence of otitis media in infants and young children by enterally administering indigestible oligosaccharides. More specifically, the present invention relates to a method for reducing the incidence of otitis media comprising administering to humans an indigestible oligosaccharide selected from the group consisting of fructooligosaccharides, fructosans, xylooligosaccharides and galactooligosaccharides. The indigestible oligosaccharides can be produced through enzymatic synthesis, chemical techniques or isolated from plant materials and are administered in the form of a nutritional product, candy, tablets, chewing gums, lozenges, milk products, yogurts and the like. In a preferred embodiment of this invention, the indigestible oligosaccharides have a DP of 2 to 20 and still more preferably are the fructooligosaccharides GF2, GF3 and GF4.
Abstract:
Embodiments described herein provide a pipetting apparatus with leak detection and a method for detecting a leak. In one embodiment, an automatic pipetting apparatus comprises a nozzle having a lower end portion through which a fluid sample is aspirated and dispensed by changes in air pressure supplied to the nozzle. A piping system operatively connects the nozzle to a pump for supplying the air pressure to the nozzle. A pressure sensor is operatively connected with the piping system for measuring internal pressure in the piping system. Means is operatively connected with the nozzle for three-dimensionally moving the nozzle between an aspirating position of the fluid sample and a dispensing position. Leak detecting means is operatively connected with the pressure sensor for detecting a leak in the piping system based upon a measured result obtained by measuring the internal pressure in the piping system with the pressure sensor while the nozzle, which has aspirated a predetermined volume of the fluid sample, is being moved between the aspirating position and the dispensing position by the moving means.
Abstract:
An improved immunoassay for detecting the presence of anti-HIV-1 or anti-HIV-2 antibody that may be present in a test sample is provided. A composition comprising site specifically haptenated peptide conjugates and test kits also are provided.
Abstract:
A mammalian expression system capable of generating recombinant proteins from non-secretor genes. Also provided are an assay which utilizes the fusion protein, a test kit which contains the fusion protein, a diagnostic reagent which comprises the fusion protein, and a vaccine which utilizes the fusion protein produced by the disclosed plasmid.
Abstract:
A method for reducing background caused by target-independent generation of amplification products, typically the products of a ligase chain reaction or a polymerase chain reaction, involves chemically "masking" or blocking the amplification probes or primers so that they cannot be extended or ligated until the occurence of a triggering event which can be delayed until the amplification reaction is begun. The probe masks take the form of complementary blocking oligonucleotides that are incapable of serving as template themselves and inhibit random tailing of the probe/primers. The blocking oligo masks are denatured from the probes during amplification and preferably are effectively eliminated from competing for probes in the amplification reaction
Abstract:
Processes are disclosed for the preparation of (2S, 3S, 5S)-5-(N-(N-((N-Methyl-N-((2-isopropyl-4-thiazolyl)methyl)amino)carbonyl)-L-valinyl)amino)-2-(N-((5-thiazolyl)methoxycarbonyl)amino)-1,6-diphenyl-3-hydroxyhexane or an acid addition salt thereof and (2S, 3S, 5S)-5-(N-(N-((N-Methyl-N-((2-isopropyl-4-thiazolyl)methyl)amino)carbonyl)-D-valinyl)amino)-2-(N-((5-thiazolyl)methoxycarbonyl)amino-1,6-diphenyl-3-hydroxyhexane or an acid addition salt thereof.
Abstract:
1 alpha ,25-dihydroxycholecalciferol is a naturally occurring form of Vitamin D3. Vitamin D3 is converted to 1 alpha , 25-dihydroxycholecalciferol in the liver and kidney before it acts to stimulate intestinal calcium and phosphorous absorption. Parenteral solutions of 1 alpha , 25-dihydroxycholecalciferol are suitable for replacement therapy.
Abstract:
Antimicrobial compounds having formula (I) as well as pharmaceutical compositions comprising such compounds and methods of treating bacterial infection and colitis by the administration thereof.
