| heart septal defects, ventricular | Congenital defects in the septum between the cardiac ventricles, most often due to failure of the bulbar septum to completely close the interventricular foramen. (12 Dec 1998) |
|---|---|
| endocardial cushion defects | A spectrum of septal defects associated with persistence of the embryonic atrioventricular canal due to incomplete growth and fusion of the endocardial cushion. (12 Dec 1998) |
| furcation defects | Conditions in which a bifurcation or trifurcation of the molar tooth root becomes denuded as a result of periodontal disease. It may be followed by tooth mobility, temperature sensitivity, pain, and alveolar bone resorption. (12 Dec 1998) |
| aromatic series | All the compounds derived from benzene, or similar cyclic compounds that obey Huckel's rule, distinguished from those compounds that are acyclic or that contain rings that lack the conjugated double bond structure characteristic of benzene. (05 Mar 2000) |
| granulocytic series | <haematology> The cells in the several stages of development in the bone marrow leading to the mature granulocyte of the circulation, e.g., myeloblasts, different stages of the myelocyte, granulocytes. (05 Mar 2000) |
| myeloid series | The granulocytic and the erythrocytic series. (05 Mar 2000) |
| Hofmeister series | <chemistry> The series of cations Magnesium, Calcium, Sr2+, Ba2+, Li+, Na+, K+, Rb+, Cs+, and of anions citrate3-, tartrate2-, SO42-, acetate-, NO3-, CIO3-, I-, CNS- (among others). Each series is arranged in order of decreasing ability to: 1) precipitate the dispersed substance of lyophilic soltions; 2) "salt out" organic substances (e.g., aniline, ethyl acetate) from aqueous solutions; or 3) inhibit the swelling of gels. These effects, among other related ones, are ascribable to the abstraction and binding of water by these ions (i.e., hydration), which also decreases in the orders given, so that (in the monovalent cation series) Li+, with the smallest crystal radius, has the largest hydrated radius, and vice versa for Cs+. Synonym: lyotropic series. (05 Mar 2000) |
| homologous series | A series of organic compounds, the succeeding members of which differ from each other by the radical CH2 (as in the fatty series). (05 Mar 2000) |
| series | 1. A number of things or events standing or succeeding in order, and connected by a like relation; sequence; order; course; a succession of things; as, a continuous series of calamitous events. "During some years his life a series of triumphs." (Macaulay) 2. <biology> Any comprehensive group of animals or plants including several subordinate related groups. Sometimes a series includes several classes; sometimes only orders or families; in other cases only species. 3. <mathematics> An indefinite number of terms succeeding one another, each of which is derived from one or more of the preceding by a fixed law, called the law of the series; as, an arithmetical series; a geometrical series. Origin: L. Series, fr. Serere, sertum, to join or bind together; cf. Gr. To fasten, Skr. Sarit thread. Cf. Assert, Desert a solitude, Exert, Insert, Seraglio.

| small bowel series | Radiographic examination of the small intestine following the oral administration of contrast medium, usually barium sulfate. Compare: small bowel enema. (05 Mar 2000) |
| soil series | A group of soils having horizons similar in differentiating characteristics and arrangements in the soil profile, except for texture of the surface layer. (09 Oct 1997) |
| thrombocytic series | The cells of successive stages in thrombocytic (platelet) development in the bone marrow, e.g., thromboblasts, thrombocytes. (05 Mar 2000) |
| erythrocytic series | The cells in the various stages of development in the red bone marrow leading to the formation of the erythrocyte, e.g., erythroblasts, normoblasts, erythrocytes. (05 Mar 2000) |
| type series | <zoology> The series of specimens which either constitutes the name-bearing type of a nominal species or subspecies or from which the name-bearing type has been or may be designated. (09 Jan 1998) |
| fatty series | The alkanes; all the acyclic compounds in the methane, ethane, propane, etc., group, distinguished from the aromatic series. (05 Mar 2000) |
