Metaphase Spindle Assembly [PDF]

open access: yesBiology, 2017
A microtubule-based bipolar spindle is required for error-free chromosome segregation during cell division. In this review I discuss the molecular mechanisms required for the assembly of this dynamic micrometer-scale structure in animal cells.

Sleep spindle deficits in antipsychotic-naïve early course schizophrenia and in non-psychotic first-degree relatives

open access: yesFrontiers in Human Neuroscience, 2014
Introduction: Chronic medicated patients with schizophrenia have marked reductions in sleep spindle activity and a correlated deficit in sleep-dependent memory consolidation.

Mitotic Spindle: Illuminating Spindle Positioning with a Biological Lightsaber [PDF]

open access: yesCurrent Biology, 2018
In metazoans, positioning of the mitotic spindle is controlled by the microtubule-dependent motor protein dynein, which associates with the cell cortex. Using optogenetic tools, two new studies examine how the levels and activity of dynein are regulated at the cortex to ensure proper positioning of the mitotic spindle.

Force on spindle microtubule minus ends moves chromosomes

open access: yesJournal of Cell Biology, 2014
After the loss of continuous spindle microtubule attachment to the spindle pole, a previously undescribed mechanism of chromosome transport, powered by dynein pulling on minus ends of severed microtubules, repairs spindle architecture and integrity.

Tool post modification allows easy turret lathe cutting-tool alignment [PDF]

open access: yes, 1966
Modified tool holder and tool post permit alignment of turret lathe cutting tools on the center of the spindle. The tool is aligned with the spindle by the holder which is kept in position by a hydraulic lock in feature of the tool post. The tool post is
