Lengthening without letting go
erotelic chromosome attachments present the cell with a particularly threatening scenario. With a single kinetochore attached to both spindle poles, the tension on this kinetochore ensures that no error message is sent out, as would be the case with a detached kinetochore. Most researchers presumed that the relatively lower tension on the " incorrect " attachment (the one that is relieved by th...
متن کاملLimb Lengthening by Implantable Limb Lengthening Devices
Implantable limb lengthening using noninvasively adjusted telescopic nails dates back to 1983. The newest technology is the Precice (Ellipse Technologies). A retrospective study of the first 65 Precice nails was carried out for the treatment of limb length discrepancy (unilateral) and short stature (bilateral). Successful lengthening was achieved in all patients. There were numerous distraction...

Text by Hema Bashyam [email protected] Skin-based immunity W hen skin cells are hit by a blast of UV light, they instruct dendritic cells (DCs) to suppress immunity system-wide, say Karin Loser, Stefan Beissert (University of Münster, Münster, Germany), and colleagues. UV has the unusual ability to cause immunosuppression by recruiting T regulatory cells (T regs). UV has thus been used t...
متن کاملOrbital Shrinking
Symmetry plays an important role in optimization. The usual approach to cope with symmetry in discrete optimization is to try to eliminate it by introducing artificial symmetry-breaking conditions into the problem, and/or by using an ad-hoc search strategy. In this paper we argue that symmetry is instead a beneficial feature that we should preserve and exploit as much as possible, breaking it o...
متن کاملMyotopography in Tibial Lengthening
Limb lengthening by Ilizarov lengthens not just the long bone, but also the soft tissues too. Damage of the musclesduring corticotomy and their stretching during distraction play a crucial role in occurrence of complications and finallimb function. We present here a systematic codified nomenclature system of each muscle summarising all theinfluence that corticotomy and distraction have the part...
