Abstract: The developed reagent is three-color immunophenotyping reagent for measurement of CD4 positive lymphocytes in peripheral blood. The reagent contains 7-aminoactinomycin D (7-AAD) which intercalates into double stranded DNA and is easily excited at 488 nm. The fluorescence emission of 7-AAD has peak at 670 nm that can be detected with FL3 detector of flow cytometer. The 7-AAD, therefore, stains white blood cells and discriminates it from red blood cells. The reagent also contains fluorescein isothiocyanate (FITC) labeled CD4 monoclonal antibody and phycoerythrin (PE) labeled CD14 monoclonal antibody which are detected with FL1 and FL2 detectors of flow cytometer, respectively. The developed reagent can be used to measure number of CD4 positive lymphocytes in lymphocyte population and monitor monocyte contamination simultaneously. This reagent therefore provides more accuracy results of CD4 positive lymphocyte enumeration.

Abstract: The present disclosure provides a series of compositions, or a single composition formulation (e.g., which includes distinct time release portions), supportive of or resulting in antipode immune system effects. A method of administrating the series of compositions or the single composition formulation to support, provide, enhance, or improve health benefit by way of modulating aspects immune system function is also provided.

Abstract: The invention provides a device and method for the rapid identification of patients suspected of having thalassemia. The invention provides a test strip for the aqueous detection of thalassemia related proteins in whole blood. The test strip includes antibodies specific to the gamma 4, (?4) protein and provides easy visual discrimination between a positive result and a negative result. The invention can be used in remote or clinical settings.

Abstract: The invention includes a genetic construct and a mutant dengue virus, designated as strain MBU 01-2002, which is a mutant dengue virus generated by genetic modification of the 13-amino acid sequence just proximal to the pr-M junction within the prM coding region of the genome. The modification involves increasing the number of positively charged amino acids and abolishing the negatively charged amino acids in this pr-M junction sequence. The mutant dengue virus strain MBU 01-2002 possesses less prM protein on the viral envelope than the prototype dengue virus, is capable of inducing infected C6/36 cells to fuse at neutral pH, is as efficient as the prototype virus in the intracellular multiplication, but is defective in its release from infected cells.

Abstract: The present specification discloses methods of determining risk of developing Dengue Hemorrhagic Fever/Dengue Shock Syndrome (DHF/DSS) in an individual infected with dengue virus (DV). The methods comprise determining, in a fluid or tissue sample of an individual, the presence, absence or quantity of dengue virus protein NS1, and determining, in a fluid or tissue sample of the individual, presence, absence or quantity of SC5b-9 complement complex. The methods can further comprise comparing the levels of NS1 protein and SC5b-9 complement complex with a database comprising epidemiological data correlating levels of NS1 protein and SC5b-9 complement complex with probability of developing DHF/DSS in a population.
