Evolution and persistence of the cilium [PDF]

Cell Motility, 2007
AbstractThe origin of cilia, a fundamental eukaryotic organelle, not present in prokaryotes, poses many problems, including the origins of motility and sensory function, the origins of nine‐fold symmetry, of basal bodies, and of transport and selective mechanisms involved in ciliogenesis. We propose the basis of ciliary origin to be a self‐assembly RNA

Generic flow profiles induced by a beating cilium [PDF]

Eur. Phys. J. E 35 (2012) 72, 2012
We describe a multipole expansion for the low Reynolds number fluid flows generated by a localized source embedded in a plane with a no-slip boundary condition. It contains 3 independent terms that fall quadratically with the distance and 6 terms that fall with the third power.

Spontaneous creation of macroscopic flow and metachronal waves in an array of cilia [PDF]

, 2006
Cells or bacteria carrying cilia on their surface show many striking features : alignment of cilia in an array, two-phase asymmetric beating for each cilium, coordination between cilia and existence of metachronal waves with a constant phase difference between two adjacent cilia.

The primary cilium at a glance [PDF]

Journal of Cell Science, 2010
The primary cilium, which was first so named by Sergei Sorokin ([Sorokin, 1968][1]), is a solitary organelle that emanates from the cell surface of most mammalian cell types during growth arrest.

Hydrodynamic flow patterns and synchronization of beating cilia [PDF]

Phys. Rev. Lett. 96, 058102 (2006), 2005
We calculate the hydrodynamic flow field generated far from a cilium which is attached to a surface and beats periodically. In the case of two beating cilia, hydrodynamic interactions can lead to synchronization of the cilia, which are nonlinear oscillators.

Seeing through the cilium [PDF]

The Journal of Cell Biology, 2002
![Graphic][1] IFT88 (green) is found in mouse photoreceptor cilia (red).To understand vision in vertebrates, one might look to worms and algae, according to recent results. On [page 103][2], Pazour et al.

Kinematics of the most efficient cilium [PDF]

Phys. Rev. Lett. 109, 038101 (2012), 2012
In a variety of biological processes, eukaryotic cells use cilia to transport flow. Although cilia have a remarkably conserved internal molecular structure, experimental observations report very diverse kinematics. To address this diversity, we determine numerically the kinematics and energetics of the most efficient cilium.

Targeting of CRMP-2 to the primary cilium is modulated by GSK-3β. [PDF]

PLoS ONE, 2012
CRMP-2 plays a pivotal role in promoting axon formation, neurite outgrowth and elongation in neuronal cells. CRMP-2's role in other cells is unknown. Our preliminary results showed CRMP-2 expression in cilia of fibroblasts. To localize CRMP-2, define its

Proteomic analysis of a eukaryotic cilium [PDF]

The Journal of Cell Biology, 2005
Cilia and flagella are widespread cell organelles that have been highly conserved throughout evolution and play important roles in motility, sensory perception, and the life cycles of eukaryotes ranging from protists to humans. Despite the ubiquity and importance of these organelles, their composition is not well known. Here we use mass spectrometry to

Cilium and VDM -- Towards Formal Analysis of Cilium Policies [PDF]

arXiv
Industrial control systems are becoming more distributed and interconnected to allow for interaction with modern computing infrastructures. Furthermore, the amount of data generated by these systems is increasing due to integration of more sensors and the need to increase the reliability of the system based on predictive data models.
