| frozen-in flow law | <radiobiology> In a perfect conductor, the total magnetic flux through any surface is a constant. In a plasma which is nearly perfectly conducting, the relevant surfaces move with the plasma, the result is that the plasma is tied to the magnetic field, and the field is tied to the plasma. Motion of the plasma thus deforms the magnetic field, and vice versa. The magnetic flux is said to be frozen into the plasma. (09 Oct 1997) |
| frozen pelvis | A condition in which the true pelvis is indurated throughout, especially by carcinoma. Synonym: hardened pelvis. (05 Mar 2000) |
| frozen section | <technique> Part of biopsy material frozen immediately to enable pathological analysis in a few minutes on a microscope slide. (16 Dec 1997) |
| frozen sections | Thinly cut sections of frozen tissue specimens prepared with a cryostat or freezing microtome. (12 Dec 1998) |
| frozen shoulder | <orthopaedics, rheumatology> This disorder results from any conditions that enforce prolonged immobility of the shoulder joint. The shoulder is painful and tender to palpation. There is marked restriction of passive and active range of motion. Physical therapy and corticosteroid injections may be helpful in some cases. Surgery will be required for more advanced cases. (27 Sep 1997) |
| frozen stock | <cell culture> Because cell lines tend to change their properties with continuous rounds of subculturing, it is common practice to keep stocks of cells frozen (either in liquid nitrogen or at 70_C) and to keep returning to this stock so that experiments are all carried out on cells of comparable passage number. The method also allows strains to be stored for long periods. Cells are usually frozen down in the presence of a cryoprotectant such as DMSO or glycerol. The method is also extensively used for storing semen for artificial insemination. (18 Nov 1997) |
| antihemophilic plasma | Human plasma in which the labile antihemophilic globulin component, present in fresh plasma, has been preserved; it is used to temporarily relieve dysfunction of the haemostatic mechanism in haemophilia. (05 Mar 2000) |
| apical plasma membrane | <cell biology> The term used for the cell membrane on the apical (inner or upper) surface of transporting epithelial cells. This region of the cell membrane is separated, in vertebrates, from the baso lateral membrane by a ring of tight junctions that prevents free mixing of membrane proteins from these two domains. (18 Nov 1997) |
| basolateral plasma membrane | <cell biology> The plasma membrane of epithelial cells that is adjacent to the basal lamina or the adjoining cells of the sheet. Differs both in protein and phospholipid composition from the apical plasma membrane from which it is isolated by tight junctions (zonula occludentes). (18 Nov 1997) |
| beam-plasma reaction | <radiobiology> Fusion reaction which occurs from the collision of a fast beam ion with a thermal plasma ion. (09 Oct 1997) |
| bean-shaped plasma | <radiobiology> A toroidal plasma indented on the inboard side (the side with the donut hole), that results in additional stability to ballooning modes. Moderate indentation may provide access to the second-stability region (high beta). (13 Nov 1997) |
