Abstract:
A liquid nutritional product for enteral feeding contains a fat source which provides desirable effects when fed to pulmonary patients. The fat source provides a ratio, by weight, of n-6 to n-3 fatty acids in the range of about 1.5 to about 3.0, a ratio of Linoleic acid (18:2n6) to Alpha-Linolenic acid (18:3n3) in the range of about 3.0 to about 10.0, and a ratio of the sum of Eicosapentaenoic acid (20:5n3) and Docosahexaenoic acid (22:6n3) to Gamma-Linolenic acid (18:3n6) in the range of about 1.0 to about 10.0. In a preferred embodiment the nutritional product contains quantities of nutrients having antioxidant properties in vivo, such as beta-carotene, vitamin E, vitamin C, selenium, and taurine.
Abstract:
The present invention relates to a method for directly measuring concentrations of cholesterol associated with specific lipoproteins in a plasma sample. The method involves the specific capture of intact lipoprotein particles containing cholesterol from a plasma sample with a specific lipoprotein binding agent. The quantity of the specific lipoprotein cholesterol present in the sample is then measured by detecting the amount of binding-agent-lipoprotein complexes that have formed in the reaction. The cholesterol contained in the binding-agent-lipoprotein complexes can be detected by reacting the complexes with labeled cholesterol specific binding agents and measuring the amount of label bound thereto, or by releasing the cholesterol in the complexes and measuring the amount of cholesterol released. The specific lipoprotein binding agent can be bound to a solid support. The assay method may also incorporate a further step of separating the solid support from the sample before detecting the presence of cholesterol bound to the solid support.

Abstract:
Selenium is provided in a nutritional product by incorporating selenate into a premix with an iron (II) and/or copper (II) salt which is water soluble and then combining the premix with a source of nutrition to form a nutritional product.
Abstract:
A method for identifying, characterizing, categorizing and enumerating cells. The method is based on the survival of different cell populations in the sample when the sample condition is being changed to elicit a response. The cells are being monitored either by direct disappearance of intact cells or by the appearance of cell structures, carcasses, ghosts or residuum. In one embodiment, a leukocyte cell decay rate in the presence of an erythrolytic agent is determined by monitoring leukocyte counts at several time intervals. The decay rate is used to determine the presence of fragile leukocyte and the number of leukocytes in the sample. The method corrects errors in leukocyte counts which enables the use of strong erythrolytic agents in presence of lyse-resistant erythrocytes. The leukocyte decay rate can be back extrapolated to time zero to provide an accurate estimate of the leukocyte count initially present in the sample.
Abstract:
Novel pyrene-trisulfonate derivatives and the use thereof in a method for the determination of glycohydrolitic enzyme activity are provided. The method comprises the steps of (a) forming a test solution comprising a test sample containing the glycohydrolitic enzyme and a pyrene-trisulfonate derivative of the present invention, wherein the derivative is hydrolyzed by the glycohydrolytic enzyme to result in the formation of free 8-hydroxy-1,3,6-pyrene trisulfonate as a function of, and which can be correlated to, the amount of the glycohydrolytic enzyme present in the test sample, and (b) measuring and correlating either the intensity of fluorescence, or the optical density, of the test solution to the presence or amount of the glycohydrolytic enzyme in the test sample. A preferred pyrene-trisulfonate derivative is pyrene-(1,3,6-trisulfonic acid)-8-β-D-glucuronide for the determination of β-D-glucuronidase for the diagnosis of periodontal disease.
Abstract:
A direct method for detecting viral nucleic acid of HIV-1 in a biological sample suspected of containing the target nucleic acid by adsorption of the biological sample onto a solid support coupled to an anti-HIV-1 envelope antibody, followed by amplification of the target nucleic acid sequence and detection of the amplified product. Amplification methods which can be used include the polymerase chain reaction and the ligase chain reaction.
Abstract:
The present invention provides a method of making low molecular weight urokinase-type plasminogen activator comprising cleaving high molecular weight urokinase-type plasminogen activator with the metalloproteinase pump-1. Pharmaceutical compositions and methods of thrombolysis or preventing blood clot formation using that low molecular weight urokinase-type plasminogen activator are also provided.
Abstract:
4''-Deoxy derivatives of erythromycin having formula (I) and pharmaceutically acceptable salts thereof, which are enhancers of gastric motility but have minimal antibacterial activity, as well as pharmaceutical compositions containing the same and methods for their use and preparation.
Abstract:
Prolamine fractions of grain proteins, applied in weight ratios of 5 to 100 % relative to the active agent being coated, effectively prevent the partitioning of water-soluble or water-insoluble drugs at neutral pH's in the mouth and thereby mask the taste of orally-administered drugs, which normally have a bitter taste, without sacrificing bioavailability. Zein, gliadin or a mixture thereof, particularly in combination with between 2.5 and 15 % of water-insoluble vegetable source oil or wax capable of plasticizing the prolamine fraction, when applied to particles, granules, tablets or other forms of drugs or nutritionals, to an effective thickness of about 1 to about 35 micrometers, in order to encapsulate and prevent release of an orally-administered pharmaceutical or nutritional in a suspension or chewable dosage form until such medicament reaches the stomach.
