Chromosome movement in lysed mitotic cells is inhibited by vanadate. [PDF]

, 1978
Mitotic PtK1 cells, lysed at anaphase into a carbowax 20 M Brij 58 solution, continue to move chromosomes toward the spindle poles and to move the spindle poles apart at 50% in vivo rates for 10 min.

Biocompatible Ink Optimization Enables Functional Volumetric Bioprinting With Xolography

Advanced Materials, EarlyView.
Xolography's reliance on weak‐base co‐initiators introduces unique biochemical constraints. By dissecting the effects of extracellular pH, osmolality, and lysosomotropic stress, this study defines the biochemical design space that enables fully biocompatible, cell‐laden volumetric printing. Abstract Xolography is a novel linear volumetric manufacturing

Method for Vibration Response Simulation and Sensor Placement Optimization of a Machine Tool Spindle System with a Bearing Defect

Sensors, 2012
Bearing defects are one of the most important mechanical sources for vibration and noise generation in machine tool spindles. In this study, an integrated finite element (FE) model is proposed to predict the vibration responses of a spindle bearing ...

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

Nature 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.

Macrophages Mediate Mesoscale Brain Mechanical Homeostasis

Advanced Materials, EarlyView.
We investigated the role of infiltrating immune cells in sculpting the developing brain. Using Brillouin microscopy and active microrheology, we found microglia actively maintain tissue viscoelasticity. Moreover, colony stimulating factor one receptor (CSF1R)‐driven stromal remodeling alters brain mechanics in vivo. These findings link immune activity,

Multifunctional Small Intestinal Submucosa Mesh for Scarless Abdominal Wall Defect Repair

Advanced Materials Interfaces, EarlyView.
a) Schematic illustration of the SIS/PCA/Mg mesh preparation. b) Schematic illustration of the repair of full‐thickness abdominal wall defects by multifunctional and degradable SIS/PCA/Mg mesh. ABSTRACT Decellularized small intestinal submucosa (SIS) mesh used for the treatment of abdominal wall defects often suffers from a high risk of recurrence due ...

A comparison of two sleep spindle detection methods based on all night averages: individually adjusted vs. fixed frequencies

Frontiers in Human Neuroscience, 2015
Sleep spindles are frequently studied for their relationship with state and trait cognitive variables, and they are thought to play an important role in sleep-related memory consolidation.

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

Current 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.
