Vpx: Vpx is a virion-associated protein encoded by human immunodeficiency virus type 2 HIV-2 and most simian immunodeficiency virus (SIV) strains, but that is absent from HIV-1. It is similar in structure to the protein Vpr that is carried by SIV and HIV-2 as well as HIV-1.Carbon–carbon bond: A carbon–carbon bond is a covalent bond between two carbon atoms. The most common form is the single bond: a bond composed of two electrons, one from each of the two atoms.Envelope glycoprotein GP120: Envelope glycoprotein GP120 (or gp120) is a glycoprotein exposed on the surface of the HIV envelope. The 120 in its name comes from its molecular weight of 120 kDa.Conference on Retroviruses and Opportunistic Infections: The Conference on Retroviruses and Opportunistic Infections (CROI) is an annual scientific meeting devoted to the understanding, prevention and treatment of HIV/AIDS and the opportunistic infections associated with AIDS. Thousands of leading researchers and clinicians from around the world convene in a different location in North America each year for the Conference.Statnamic load test: The Statnamic load test is a type of test for assessing the load carrying capacity of deep foundations which is faster and less expensive than the static load test. The Statnamic test was conceived in 1985, with the first prototype tests carried out in 1988 through collaboration between Berminghammer Foundation Equipment of Canada and TNO Building Research of the Netherlands (Middendorp et al.CCR5 receptor antagonist: CCR5 receptor antagonists are a class of small molecules that antagonize the CCR5 receptor. The C-C motif chemokine receptor CCR5 is involved in the process by which HIV, the virus that causes AIDS, enters cells.Coles PhillipsAdult-onset immunodeficiency syndrome: Adult-onset immunodeficiency syndrome is a provisional name for a newly diagnosed immunodeficiency illness. The name is proposed in the first public study to identify the syndrome.KeliximabPol (HIV): Pol (DNA ymerase) refers to a gene in retroviruses, or the protein produced by that gene.CXC chemokine receptors: CXC chemokine receptors are integral membrane proteins that specifically bind and respond to cytokines of the CXC chemokine family. They represent one subfamily of chemokine receptors, a large family of G protein-linked receptors that are known as seven transmembrane (7-TM) proteins, since they span the cell membrane seven times.Management of HIV/AIDS: The management of HIV/AIDS normally includes the use of multiple antiretroviral drugs in an attempt to control HIV infection. There are several classes of antiretroviral agents that act on different stages of the HIV life-cycle.Discovery and development of nucleoside and nucleotide reverse-transcriptase inhibitors: Discovery and development of nucleoside and nucleotide reverse-transcriptase inhibitors (NRTIs and NtRTIs) began in the 1980s when the AIDS epidemic hit Western societies. NRTIs inhibit the reverse transcriptase (RT), an enzyme that controls the replication of the genetic material of the human immunodeficiency virus (HIV).Protein primary structure: The primary structure of a peptide or protein is the linear sequence of its amino acid structural units, and partly comprises its overall biomolecular structure. By convention, the primary structure of a protein is reported starting from the amino-terminal (N) end to the carboxyl-terminal (C) end.HIV-positive people: HIV-positive people are people who have the human immunodeficiency virus HIV, the agent of the currently incurable disease AIDS.Protease inhibitor (pharmacology): Protease inhibitors (PIs) are a class of antiviral drugs that are widely used to treat HIV/AIDS and hepatitis caused by hepatitis C virus. Protease inhibitors prevent viral replication by selectively binding to viral proteases (e.Co-option (biology)Nef (protein): coordinates.Symmetry element: A symmetry element is a point of reference about which symmetry operations can take place. In particular, symmetry elements can be centers of inversion, axes of rotation and mirror planes.Viral infectivity factor: Viral infectivity factor, or Vif, is a protein found in HIV and other retroviruses. Its role is to disrupt the antiviral activity of the human enzyme APOBEC (See also APOBEC3G) by targeting it for ubiquitination and cellular degradation.Vpr: Vpr is a Human immunodeficieny viral gene and protein product.Cro repressor family: In molecular biology, the Cro repressor family of proteins includes the bacteriophage lambda Cro repressor.Plaque reduction neutralization test: The Plaque reduction neutralization test is used to quantify the titre of neutralising antibody for a virus.Silent mutation: Silent mutations are mutations in DNA that do not significantly alter the phenotype of the organism in which they occur. Silent mutations can occur in non-coding regions (outside of genes or within introns), or they may occur within exons.Host tropism: Host tropism is the name given to a process of tropism that determines which cells can become infected by a given pathogen. Various factors determine the ability of a pathogen to infect a particular cell.Natural transfer: The natural transfer (hypothesis or theory), in reference to the HIV/AIDS pandemic, states that humans first received HIV by contact with primates, presumably from a fight with a Chimpanzee during hunting or consumption of primate meat, and became contaminated with simian immunodeficiency virus (SIV). According to the 'Hunter Theory', the virus was transmitted from a chimpanzee to a human when a bushmeat hunter was bitten or cut while hunting or butchering an animal.Cognitive effects of HIVAvian HBV RNA encapsidation signal epsilonRev (HIV): Rev is a transactivating protein that is essential to the regulation of HIV-1 protein expression. A nuclear localization signal is encoded in the rev gene, which allows the Rev protein to be localized to the nucleus, where it is involved in the export of unspliced and incompletely spliced mRNAs.Branching order of bacterial phyla (Gupta, 2001): There are several models of the Branching order of bacterial phyla, one of these was proposed in 2001 by Gupta based on conserved indels or protein, termed "protein signatures", an alternative approach to molecular phylogeny. Some problematic exceptions and conflicts are present to these conserved indels, however, they are in agreement with several groupings of classes and phyla.Proximity ligation assay: Proximity ligation assay (in situ PLA) is a technology that extends the capabilities of traditional immunoassays to include direct detection of proteins, protein interactions and modifications with high specificity and sensitivity. Protein targets can be readily detected and localized with single molecule resolution and objectively quantified in unmodified cells and tissues.Tingible body macrophage: A tingible body macrophage is a type of macrophage predominantly found in germinal centers, containing many phagocytized, apoptotic cells in various states of degradation, referred to as tingible bodies (tingible meaning stainable).Horst Ibelgaufts' COPE: Cytokines & Cells Online Pathfinder Encyclopaedia > tingible body macrophages Retrieved on June 27, 2010 Tingible body macrophages contain condensed chromatin fragments.CyclophilinNevirapineReaction coordinateDNA binding site: DNA binding sites are a type of binding site found in DNA where other molecules may bind. DNA binding sites are distinct from other binding sites in that (1) they are part of a DNA sequence (e.APOBEC4: C->U-editing enzyme APOBEC-4, also known as Apolipoprotein B mRNA-editing enzyme catalytic polypeptide-like 4, is a protein that in humans is encoded by the APOBEC4 gene.Antiviral drug: Antiviral drugs are a class of medication used specifically for treating viral infections. Like antibiotics for bacteria, specific antivirals are used for specific viruses.Genetic variation: right|thumbThermal cyclerCryptic self epitopes: In immunology, cryptic self epitopes are a source of autoimmunity.Multiple cloning site: A multiple cloning site (MCS), also called a polylinker, is a short segment of DNA which contains many (up to ~20) restriction sites - a standard feature of engineered plasmids. Restriction sites within an MCS are typically unique, occurring only once within a given plasmid.
