Industry:Health care
The second of seven steps in the HIV life cycle. During reverse transcription, HIV uses reverse transcriptase (an HIV enzyme) to convert genetic information carried in HIV RNA to make HIV DNA.
Industry:Health care
The second step in testing an experimental drug (or other treatment) in humans. Typically, Phase II trials are done only if Phase I trials have shown that the drug is safe, but sometimes Phase I and Phase II trials are combined. Phase II trials are designed to evaluate the drug's effectiveness in people with the disease or condition being studied and to determine the common short-term adverse effects and risks associated with the drug. Phase II trials involve more participants (often several hundred) and typically last longer than Phase I trials.

The sequence of events required for HIV to replicate. There are seven steps in the HIV life cycle: 1) fusion; 2) reverse transcription; 3) integration; 4) transcription; 5) translation; 6) budding; 7) maturation.

Industry:Health care
The sixth of seven steps in the HIV life cycle. During budding, new HIV RNA and HIV proteins made by the host cell move to the surface of the host cell and assemble into an immature (noninfectious) HIV. After the immature HIV is formed, the virus pushes itself out of the host cell, taking with it part of the host cell’s outer membrane.
Industry:Health care
The soft, sponge-like tissue in the center of bones. There are two types of bone marrow: yellow (made up of mostly fat cells) and red (the source of red blood cells, platelets, and most white blood cells).
Industry:Health care
The state of being mortal (subject to death). Mortality rate is a measure of the frequency of occurrence of death among a defined population during a specified time period.
Industry:Health care
The state of either having or not having detectable antibodies against a specific antigen, as measured by a blood test (serologic test). For example, HIV seropositive means that a person has detectable antibodies to HIV; seronegative means that a person does not have detectable HIV antibodies.
Industry:Health care
The strongest form of warning required by the Food and Drug Administration (FDA) for prescription drug labeling. A boxed warning alerts health care providers and consumers to increased risk of serious adverse reactions associated with use of a drug or to restrictions on use of a drug. The boxed warning is presented in a box surrounded by a black border and is placed on the drug label and any package inserts or promotional materials intended for the prescriber or patient.
