On the Mass of Population III Stars [PDF]

open access: yes, 1998
Performing 1D hydrodynamical calculations coupled with non-equilibrium processes for H2 formation, we pursue the thermal and dynamical evolution of filamentary primordial clouds and attempt to make an estimate on the mass of population III stars.

A narrow window of cortical tension guides asymmetric spindle positioning in the mouse oocyte

open access: yesNature Communications, 2015
Cell mechanics control the outcome of cell division. In mitosis, external forces applied on a stiff cortex direct spindle orientation and morphogenesis. During oocyte meiosis on the contrary, spindle positioning depends on cortex softening.

TRIP13 is a protein-remodeling AAA+ ATPase that catalyzes MAD2 conformation switching. [PDF]

open access: yes, 2015
The AAA+ family ATPase TRIP13 is a key regulator of meiotic recombination and the spindle assembly checkpoint, acting on signaling proteins of the conserved HORMA domain family.

Small molecule inhibitor of mitotic spindle bipolarity identified in a phenotype-based screen.

open access: yesScience, 1999
Small molecules that perturb specific protein functions are valuable tools for dissecting complex processes in mammalian cells. A combination of two phenotype-based screens, one based on a specific posttranslational modification, the other visualizing ...

Measurement of Spindle Rigidity by using a Magnet Loader

open access: yesJournal of Advanced Mechanical Design, Systems, and Manufacturing, 2010
The static rigidity of a rotating spindle in the radial direction is investigated in this research. A magnetic loading device (magnet loader) has been developed for the measurement.

Mad1 kinetochore recruitment by Mps1-mediated phosphorylation of Bub1 signals the spindle checkpoint

open access: yesGenes & Development, 2014
The mitotic spindle checkpoint ensures accurate chromosome segregation and genomic integrity. Understanding the regulation of checkpoint protein Mad1 recruitment to the kinetochore has been an outstanding question in the field.

Emerging Insights into the Function of Kinesin-8 Proteins in Microtubule Length Regulation

open access: yesBiomolecules, 2018
Proper regulation of microtubules (MTs) is critical for the execution of diverse cellular processes, including mitotic spindle assembly and chromosome segregation.

Spindle oscillations are generated in the dorsal thalamus and modulated by the thalamic reticular nucleus [PDF]

open access: yes, 2008
Spindle waves occur during the early stage of slow wave sleep and are thought to arise in the thalamic reticular nucleus (TRN), causing inhibitory postsynaptic potential spindle-like oscillations in the dorsal thalamus that are propagated to the cortex ...

Neuromorphic compliant control facilitates human-prosthetic performance for hand grasp functions

open access: yesNeuromorphic Computing and Engineering
Current bionic hands lack the ability of fine force manipulation for grasping fragile objects due to missing human neuromuscular compliance in control.

How Does SUMO Participate in Spindle Organization?

open access: yesCells, 2019
The ubiquitin-like protein SUMO is a regulator involved in most cellular mechanisms. Recent studies have discovered new modes of function for this protein.
