Exempel på spindle

• The topic of spindle-whorl classification and use has received considerable attention.

• Its rigid anti-vibration structure enables several technologies to be incorporated: laser, water jet, machining spindles or non-destructive controls.

• The present study suggests that an active cortical network participates in disrupting the spindle activities.

• We consider this unsuccessful development of reconstituted eggs to be due mainly to abnormal spindle formation and/or unequal distribution of chromatids, as described above.

• This effect occurs during cortical augmenting responses mimicking sleep spindles as well as during the self-sustained, post-augmenting activity.

• The longitudinal axis of the spindle takes an oblique angle to the egg axis.

• Cooling induced spindle disassembly and the recovery after warming in living human eggs (abstract).

• This cycle waxes and wanes at variable intervals; between spindles, thalamocortical neurons are depolarized.

• It was of interest to us to examine whether inhibition of calmodulin would affect spindle formation and/or chromatin condensation and alignment.

• At this early stage the mitotic spindle is located some 50 m from the top of the blastodisc.

• The floating bearing was assumed not to affect the error motions of the spindle assembly and was not included in the machine model.

• Therefore, during spindle recovery chromosomes may be rearranged on the spindle and mistakes in the segregation between microtubules and chromosomes may occur.

• At first sight, this may indicate a role for the 'elimination chromatin' in the organisation of the second meiotic spindle.

• Another important role for microtubules is in cell division, where they make up the spindle fibres.

• The weight, height, inner-hole diameter, and total diameter of each spindle whorl were measured.
