| rouge | 1. <chemistry> A red amorphous powder consisting of ferric oxide. It is used in polishing glass, metal, or gems, and as a cosmetic, etc. Called also crocus, jeweler's rouge, etc. 2. A cosmetic used for giving a red colour to the cheeks or lips. The best is prepared from the dried flowers of the safflower, but it is often made from carmine. Origin: F.

| rough | Not smooth; denoting the irregular, coarsely granular surface of a certain bacterial colony type. (05 Mar 2000) |
| rough colony | A bacterial colony with a granular, flattened surface; this type of colony is usually associated with loss of virulence with respect to that of smooth colony's. (05 Mar 2000) |
| rough endoplasmic reticulum | <cell biology> Membrane organelle of eukaryotes that forms sheets and tubules. Contains the receptor for the signal receptor particle and binds ribosomes engaged in translating mRNA for secreted proteins and the majority of transmembrane proteins. Also a site of membrane lipid synthesis. The membrane is very similar to the nuclear outer membrane. The lumen contains a number of proteins that possess the C terminal signal KDEL. (17 Dec 1997) |
| rough line | A rough ridge with two pronounced lips running down the posterior surface of the shaft of the femur; the lateral lip of the linea aspera is a continuation of the gluteal tuberosity, the medial lip of the intertrochanteric line; it affords attachment to the vastus medialis, adductor longus, adductor magnus, adductor brevis, the short head of the biceps, and the vastus lateralis muscles as well as to the intermuscular septa of the thigh. Synonym: rough line. (05 Mar 2000) |
| rough microsome | <cell biology> Small vesicles obtained by sonicating cells and that are derived from the rough endoplasmic reticulum. Have bound ribosomes and can be used to study protein syntheis. Origin: Gr. Soma = body (17 Dec 1997) |
| rough strain | <microbiology> Bacterial strains that have altered outer cell wall carbohydrate chains causing colonies on agar to change their appearance from smooth to dull. In Streptococci the smooth strains are virulent whereas the rough strains are not. This is partly because the rough strains are much more readily phagocytosed. (17 Dec 1997) |
| rough trees | Live trees of commercial species which do not contain a sawlog because of roughness, poor form, splits, or cracks. Includes all living trees of noncommercial species. (05 Dec 1998) |
| rough-footed | <zoology> Feather-footed; as, a rough-footed dove. Source: Websters Dictionary (01 Mar 1998) |
