Abstract: The invention provides for a system and method for minimizing space requirements and increasing speed in a geometry accelerator for a computer graphics system. In architecture, the system is implemented as follows. The geometry accelerator includes a plurality of processing elements (e.g., an arithmetic logic unit, a multiplier, a divider, a compare mechanism, a clamp mechanism, etc.) and a plurality of control units (e.g., a transform mechanism, a decomposition mechanism, a clip mechanism, a bow-tie mechanism, a light mechanism, a classify mechanism, a plane equation mechanism, a fog mechanism, etc.) that utilize the processing elements for performing data manipulations upon image data. In accordance with the invention, the control units are implemented in a read-only memory (ROM) via microcode. A next address field is associated with each of the microcode instructions and defines a location in the ROM of a next instruction to be executed.

Abstract: The invention comprises inhibiting expression of TNF-.alpha. by administering an effective amount of a stabilized activated oxygen in a matrix of chlorite ions. Preferably, a pharmaceutically acceptable formulation of tetrachlorodecaoxide is used, and more preferably, WF-10. An effective amount of WF-10 comprises up to about 0.5 ml/kg. Another embodiment of the invention is a method of treating AIDS-associated dementia comprising the step of administering to a human an amount of a stabilized activated oxygen in a matrix of chlorite ions sufficient to inhibit production of TNF-.alpha..

Abstract: The presence of clonal macrophages in pre-cancerous and cancerous tissue represents an early stage of the disease in which clonal expansion of macrophages occurs due to HIV integration or other genetic mutation. Clonally expanded macrophages induce proliferation of surrounding tissue leading to cancerous tumor growth. The invention provides methods and kits for diagnosis of HIV- and non-HIV-associated clonal expansion of macrophages in pre-cancerous and cancerous tissue. The invention also provides methods for the treatment of cancers induced by clonal macrophage expansion and proliferation of surrounding tissue.

Abstract: A method and system for generating a control program executable by an industrial controller, wherein a source program is displayed using a variable width ladder diagram. Instructions of a source program are received by a host computer, wherein the source program is compilable into the control program. A ladder diagram representative of at least one of the instructions of the source program is displayed on a display device. The ladder diagram comprises a graphical interconnection of schematic elements, at least one of which having a corresponding display width which is variable. The corresponding display width is varied in dependence upon the greater of a corresponding symbol display width and a corresponding label display width. A method and system for data communication with the industrial controller uses a hybrid error detection code.

Abstract: A method and system for generating a control program executable by an industrial controller, wherein the control program is formed using instructions from a high-level text-based language and instructions from a ladder-based language. A source program is received by a host computer. At least one instruction of the source program in the high-level text-based language is displayed on a display device along with a corresponding ladder diagram of the source program in the ladder-based language. The source program is edited in either the high-level text-based language using a first editor or the ladder-based language using a second editor. Modifications of the source program made using the first editor and the second editor are converted to a lower-level language representation.

Abstract: A novel retrovirus isolated from human lymphoma cells is disclosed. The retrovirus is characterized by a C-type retroviral particle of approximately 100 nm diameter; and an approximately 27,000 molecular weight p24 core protein. Also disclosed are cell lines from which the virus can be obtained and screening methods for detecting the presence of the virus in human sera.

Abstract: This invention provides a reagent capable of binding to T cells and having specificity for a unique sequence within the variable region of the .beta. chain of the T cell receptor, the presence of increased number of T cells carrying the unique sequence relative to the number of T cells carrying the sequence present in a normal subject being associated with a specific disease. Specific diseases such as human cancers, e.g. lymphomas; autoimmune diseases, e.g. rheumatoid arthritis; Alzheimer's disease; infectious diseases, e.g. those caused by bacteria, yeast or parasite; or allergies, may be diagnosed as follows. A suitable sample containing T cells is obtained from a subject. The sample is contacted under appropriate conditions with such a reagent. If the subject's cells contain the unique sequence, a detectable complex is formed between the reagent and T cells which contain the sequence.

Abstract: A method of inhibiting HIV replication in and cellular proliferation of HIV-infected cells. The infected cells are exposed to a single-chain ribosome inactivating protein, at a protein concentration and for an exposure period sufficient to produce a substantial reduction in (a) the level of HIV antigen or reverse transcriptase associated with the infected cells, (b) the ratio of viability of infected/uninfected T cells, and/or (c) the ratio of HIV antigen/cellular antigen in infected macrophages. The method is used to treat HIV infection in humans.

Abstract: A method of inhibiting expression of HIV antigens in human blood cells infected with HIV. The infected cells are exposed to a plant protein or glycoprotein, such as trichosanthin or momorcharin, at a concentration sufficient to (a) produce a substantial reduction in the level of HIV antigen, and (b) effect a selective reduction in the number of HIV-infected cells, with respect to uninfected cells of the same type. The method is used to treat HIV infection in humans. In another aspect, the invention includes a method of screening drug agents effective in treating HIV infection in humans.

Abstract: Specific binding members are provided for binding to lymphocytic cell surface receptors, which receptors are involved in the activation of a cell from the G.sub.0 state into the cell division cycle to proliferate. The cell surface receptors are further characterized by binding to envelope proteins of neoplasia-causing retroviruses, and/or to intact retroviral particles.
