Paracentric curve
(Math.) a curve having the property that, when its plane is placed vertically, a body descending along it, by the force of gravity, will approach to, or recede from, a fixed point or center, by equal distances in equal times; - called also a paracentric.
Paracentric motion
the motion or velocity of a revolving body, such as a planet, by which it approaches to, or recedes from, the center, without reference to its motion in space, or to its motion as reckoned in any other direction.

The structural changes involving the long arm of chromosome 3 at bands 3q21 and 3q26.2 in the forms of inversion and translocation--namely, paracentric inversion [inv(3)(q21q26.2), referred to as inv(3) hereafter] and homologous translocations [t(3;3)(q21;q26.2), referred to as t(3;3) hereafter]--in myeloid neoplasms have long been recognized.
