Abstract: The present invention relates to a substance that specifically binds a nuclear localization signal (NLS)-containing molecule. Said substance may be a naturally occurring, synthetic or recombinant antibody, or it may be a protein, a peptide or a small molecule. Preferably, said NLS-containing molecule is a HIV-1 protein, more preferably Vpr or Tat. In addition, the present invention relates to a composition or a vaccine comprising the substance of the invention, as well as methods of inhibiting viral infection through the administration thereof.

Abstract: A system for transmitting data is provided. The system includes a frame analysis system receiving frame data, such as a frame of video data, and generating region data, such as a uniform matrix size that is used to divide the frame into a predetermined set of matrices. A pixel selection system receives the region data and generates one set of pixel data for each region, such as by selecting one of the pixels contained within each of the original matrices that comprise the frame.

Abstract: The subject invention provides a method for detecting the presence of human malignant cells in a sample of tumor cells, which comprises contacting the sample with an antibody directed to an epitope present on the &bgr; subunit of human luteinizing hormone or on intact human luteinizing hormone under conditions such that the antibody forms a complex with cells present in the sample if the epitope is present on the surface of the cells, and determining whether the antibody forms such a complex. The subject invention also provides a method for determining whether a tumor present in a human subject is malignant which comprises obtaining a sample of cells from the tumor and detecting the presence of malignant cells in the sample according to the method of the subject invention.

Abstract: This invention provides methods for detecting the presence of human malignant cells in a sample of tumor cells; determining whether a tumor present in a human subject is malignant; obtaining an enriched population of live human malignant cells; determining the amount of intact luteinizing hormone in a sample; determining the ovulatory stage of a subject; determining the amount of intact follicle stimulating hormone in a sample; determining the ovulatory stage of a subject; determining the amount of intact human chorionic gonadotropin in a sample; determining whether a subject is pregnant; determining the ovulatory stage of a subject; determining the amount of free &agr; subunit of human luteinizing hormone in a sample; determining whether a subject has a malignant tumor; determining the amount of nicked human chorionic gonadotropin in a sample; and determining the likelihood of a fetus's being afflicted with Down's syndrome.
