| gene products, rex | Post-transcriptional regulatory proteins required for the accumulation of mRNAs that encode the gag and env gene products in HTLV-I and HTLV-II. The rex (regulator x; x is undefined) products act by binding to elements in the ltr. (12 Dec 1998) |
|---|---|
| gene products, tat | Trans-acting transcription factors. Nuclear proteins whose expression is required for HIV viral replication. The tat protein stimulates HIV-ltr-driven RNA synthesis for both viral regulatory and viral structural proteins. Tat stands for trans-activation of transcription. (12 Dec 1998) |
| gene products, tax | Transcriptional trans-acting proteins of the promoter elements found in the long-terminal repeats (ltr) of HTLV-I and HTLV-II. The tax (trans-activator x; x is undefined) proteins act by binding to enhancer elements in the ltr. (12 Dec 1998) |
| gene products, vif | A 23 kD regulatory protein important for virion infectivity in HIV. The protein is found in the cytoplasm of HIV-infected cells and is not absolutely required for virion formation. (12 Dec 1998) |
| gene products, vpr | Trans-acting proteins which accelerate virus replication in HIV. The vpr proteins act in trans to increase the levels of HIV specified proteins. Vpr is short for viral protein r, where r is undefined. (12 Dec 1998) |
| gene products, vpu | Non-glycosylated, membrane-associated, 16 kD proteins which are expressed in large amounts in cells infected with HIV-1. The proteins are required for efficient virion maturation and release. They are not present in HIV-2 nor in siv. Vpu is short for viral protein u, with u undefined. (12 Dec 1998) |
| meat products | Articles of food which are derived by a process of manufacture from any portion of carcasses of any animal used for food (e.g., head cheese, sausage, scrapple). (12 Dec 1998) |
| glycosylation end products, advanced | Products derived from the nonenzymatic reaction of glucose and proteins in vivo that exhibit a yellow-brown pigmentation and an ability to participate in protein-protein cross-linking. These substances are involved in biological processes relating to protein turnover and it is believed that their excessive accumulation contributes to the chronic complications of diabetes mellitus. (12 Dec 1998) |
| waste products | Debris resulting from a process that is of no further use to the system producing it. The concept includes materials discharged from or stored in a system in inert form as a by-product of vital activities. (12 Dec 1998) |
| conventional forest products | Any commercial roundwood product (boards, dimension lumber, pulp and paper products) except fuelwood. (05 Dec 1998) |
| poultry products | Food products manufactured from poultry. (12 Dec 1998) |
| household products | Substances or materials used in the course of housekeeping or personal routine. (12 Dec 1998) |
| specialty chemicals and products | Chemicals and chemical products used in a research, industrial, or household setting. Included here are the specific drug preparations, as well as the substances involved in the manufacture and stabilization of pharmaceutical preparations and agricultural agents. (12 Dec 1998) |
| natural products | Naturally occurring compounds that are end products of secondary metabolism; often, they are unique compounds for particular organisms or classes of organisms. (05 Mar 2000) |
| dairy products | Raw and processed or manufactured milk and milk-derived products. These are usually from cows (bovine) but are also from goats, sheep, reindeer, and water buffalo. (12 Dec 1998) |
