Blast Crisis definition: An advanced phase of chronic myelogenous leukemia, characterized by a rapid increase in the proportion of immature white blood cells (blasts) in the blood and bone marrow to greater than 30%.
blast phase definition: The phase of chronic myelogenous leukemia in which the number of immature, abnormal white blood cells in the bone marrow and blood is extremely high.
Blast Phase Chronic Myelogenous Leukemia definition: An advanced phase of chronic myelogenous leukemia. It is characterized by: 1. the presence of blasts in the peripheral blood or bone marrow that are at least 20% of the peripheral blood white cells or of the nucleated cells in the bone marrow respectively, or 2. an extramedullary proliferation of blasts, and/or 3. when there are large aggregates and clusters of blasts in the bone marrow biopsy specimen (adapted from WHO, 2001).
M Phase definition: The period of the cell cycle when CELLS divide their nucleus and cytoplasm.
Follicular Phase definition: The period of the MENSTRUAL CYCLE representing follicular growth, increase in ovarian estrogen (ESTROGENS) production, and epithelial proliferation of the ENDOMETRIUM. Follicular phase begins with the onset of MENSTRUATION and ends with OVULATION.
Luteal Phase definition: The period in the MENSTRUAL CYCLE that follows OVULATION, characterized by the development of CORPUS LUTEUM, increase in PROGESTERONE production by the OVARY and secretion by the glandular epithelium of the ENDOMETRIUM. The luteal phase begins with ovulation and ends with the onset of MENSTRUATION.
Mitosis definition: A type of CELL NUCLEUS division by means of which the two daughter nuclei normally receive identical complements of the number of CHROMOSOMES of the somatic cells of the species.
M phase definition: A cell cycle process comprising the steps by which a cell progresses through M phase, the part of the cell cycle comprising nuclear division. [GOC:dph, GOC:mah, ISBN:0815316194]
mitosis definition: A cell cycle process comprising the steps by which the nucleus of a eukaryotic cell divides; the process involves condensation of chromosomal DNA into a highly compacted form. Canonically, mitosis produces two daughter nuclei whose chromosome complement is identical to that of the mother cell. [GOC:dph, GOC:ma, GOC:mah, ISBN:0198547684]
M Phase definition: The part of a standard cell cycle during which mitosis and cytokinesis take place. (GO)
M Phase definition: The last cell cycle stage during which the replicated daughter chromosomes separate in to separate nuclei; cytokinesis then occurs to produce separate daughter cells. M phase consists of Prophase, Metaphase, Anaphase, and Telophase. (NCI)
Mitosis definition: The usual process of somatic reproduction of cells consisting of a sequence of modifications of the nucleus that result in the formation of two daughter cells with exactly the same chromosome and DNA content as that of the original cell. It is the process by which the body grows and replaces cells and is divided into four phases. In Prophase, paired chromosomes form, nuclear membrane disappears, the achromatic spindle appears, and polar bodies form. In Metaphase, chromosomes are arranged in the equatorial plane of the central spindle to form the monaster and chromosomes separate into exactly similar halves. In Anaphase, the two groups of daughter chromosomes separate and move along the fibers of the central spindle, each toward one of the asters, forming the diaster. In Telophase, the daughter chromosomes resolve themselves into a reticulum, the daughter nuclei are formed, and the cytoplasm divides forming two complete daughter cells.
Mitosis definition: The division of the eukaryotic cell nucleus to produce two daughter nuclei that, usually, contain the identical chromosome complement to their mother. (GO)
Mitosis definition: The process of division of somatic cells in which each daughter cell receives the same amount of DNA as the parent cell.
G0 Phase definition: A quiescent state of cells during G1 PHASE.
G1 Phase definition: The period of the CELL CYCLE preceding DNA REPLICATION in S PHASE. Subphases of G1 include "competence" (to respond to growth factors), G1a (entry into G1), G1b (progression), and G1c (assembly). Progression through the G1 subphases is effected by limiting growth factors, nutrients, or inhibitors.
G1 phase definition: A cell cycle process comprising the steps by which a cell progresses through G1 phase, one of two 'gap' phases in the cell cycle; G1 is the interval between the completion of DNA segregation (usually by mitosis or meiosis) and the beginning of DNA synthesis. [GOC:ai, GOC:dph, GOC:mah]
G1 Phase definition: Phase of the cell cycle preceding DNA synthesis (Gap 1 phase). The subphases of G1 include competence, entry (G1a), progression (G1b), and assembly (G1c), based on the effects of limiting growth factors, nutrients, or inhibitors.
G2 Phase definition: The period of the CELL CYCLE following DNA synthesis (S PHASE) and preceding M PHASE (cell division phase). The CHROMOSOMES are tetraploid in this point.
G2 phase of mitotic cell cycle definition: A cell cycle process comprising the steps by which a cell progresses through G2 phase, one of two 'gap' phases in the mitotic cell cycle; G2 is the interval between the completion of DNA synthesis and the beginning of mitosis. [GOC:dph, GOC:mah, ISBN:0815316194]
G2 phase definition: A cell cycle process comprising the steps by which a cell progresses through G2 phase, one of two 'gap' phases in the cell cycle; G2 is the interval between the completion of DNA synthesis and the beginning of DNA segregation (usually by mitosis or meiosis). [GOC:ai, GOC:dph, GOC:mah]
G2 Phase definition: Phase of the cell cycle following DNA synthesis and preceding mitosis (Gap 2 phase). The chromosomes are tetraploid in this phase.
Advanced definition: Far along in course.
Phase definition: A distinguishable part, a stage in a series of events or in a process of development, e.g. any of the varying aspects or stages in course of a disease; a fraction of a cycle.
chronic phase definition: (KRAHN-ik) Refers to the early stages of chronic myelogenous leukemia or chronic lymphocytic leukemia. The number of mature and immature abnormal white blood cells in the bone marrow and blood is higher than normal, but lower than in the accelerated or blast phase.
Accelerated Phase definition: (ak-SEL-er-ay-ted) Refers to chronic myelogenous leukemia that is progressing. The number of immature, abnormal white blood cells in the bone marrow and blood is higher than in the chronic phase but not as high as in the blast phase.
phase change definition: in physical chemistry, alteration of a physically or chemically distinct homogeneous and mechanically separable part of a system, for example the ice and steam phases of water.
Phase Transition definition: A change of a substance from one form or state to another.
Lytic Phase definition: A phase of the virus life cycle during which the virus replicates within the host cell, releasing a new generation of viruses when the infected cell lyses. (NCI)
Eluent definition: The liquid or gas entering a chromatographic bed used to effect a separation.
Phase 0 Trial definition: A clinical trial that uses an investigational agent that is available only in very limited quantities and which has never previously given to humans or for which there is extremely limited human experience. Phase 0 clinical trials are intended to enable researchers to understand the path of the drug in the body and its efficacy. Adverse event reporting in Phase 0 trials is expedited.
Continuous Phase definition: The substance in an emulsion that usually makes up the largest portion of the emulsion and contains another substance suspended within.
Dispersed Phase definition: The substance in an emulsion that is suspended or dispersed within another substance of greater volume.
phase definition: phase.
phase definition: #* ''The marketing department decided to '''phase out''' the old product.''
