  • checkpoint
  • Simultaneous mutations in one of several kinetochore and cohesion genes and a spindle checkpoint gene cause a synthetic-lethal or synthetic-sick phenotype. (nih.gov)
  • bipolar
  • B-E. Representative images ( B ) show that xBuGZ depletion reduced astral MT length, bipolar spindle formation and length, which were all rescued by His-xBuGZ. (nih.gov)
  • orientation
  • We illustrate how Pitx2 activity directs asymmetrical gonad morphogenesis by controlling mitotic spindle orientation of the developing gonad cortex and how, by modulating cyclinD1 expression during asymmetric ovarian development, Pitx2 appears to control gonad organ size. (biomedsearch.com)
  • When dynein heavy chain function was diminished only partially with RNAi, centrosome separation took place, but orientation of the mitotic spindle was defective. (nih.gov)
  • CB NB asymmetric divisions occur with a persistent spindle orientation with each new daughter born next to the previous daughter (Akong et al. (nih.gov)
  • Drosophila
  • APC2's striking asymmetric localization suggested it helps orient spindles as it does in the Drosophila male germline (Yamashita et al. (nih.gov)
  • astral
  • White dashed lines in B indicate Aurora A spindle length and longest astral MTs measured. (nih.gov)
  • Structures
  • F-H. xBuGZ depletion caused multiple sperm spindle defects ( F ), which was rescued by His-xBuGZ ( G , H ). ~500 ( G ) and ~50 ( H ) structures were analyzed in each experiment and condition. (nih.gov)
  • signals
  • A narrowest signal detector of the apparatus generates a second status signal representing a status of the narrowest pulse width of the first status signals according to the frame clock signal divided by a second predetermined number k, where k is greater than j. (google.se)
  • The overrun controller compares the currently counted result with overrun upper limit and lower limit values and generates first and second flag signals braking the rotation of the spindle motor according to the compared result. (google.se)
  • an overrun controller for (i) performing one of up-counting, down-counting and holding a previously counted result, according to the frame clock signal divided by the second predetermined number and the second status signals, (ii) comparing the currently counted result with overrun upper limit and lower limit values, and (iii) generating first and second flag signals to brake the rotation of the spindle motor according to the compared result. (google.se)
  • To achieve this, the spindle apparatus sends out two signals. (uni-muenchen.de)
  • motor
  • A control apparatus and method for controlling a velocity of a spindle motor included in an optical disk reproducing system to prevent a forward or backward overrun of a spindle motor are disclosed. (google.se)
  • cell division
  • Surprisingly, APCs are not essential for asymmetric cell division or the stereotyped division axis of central brain (CB) neuroblasts, although they do affect cell cycle progression and spindle architecture. (nih.gov)
