Isolation of Growth Cones from Mouse Brain

open access: yesBio-Protocol, 2013
Growth cones are motile structures at the tips of growing neurites, which play an essential role in regulation of growth and navigation of growing axons and dendrites of neurons in the developing nervous system.

Notes on factor price equality and biased technical change in a two-cone trade model [PDF]

open access: yes, 2006
We reconsider the effects of long-run economic growth on relative factor prices across cones of specialization. We model economic growth as exogenous technical change.

Mechanochemical regulation of growth cone motility

open access: yesFrontiers in Cellular Neuroscience, 2015
Neuronal growth cones are exquisite sensory-motor machines capable of transducing features contacted in their local extracellular environment into guided process extension during development.

Moderate repulsive effects of E-unit-containing chondroitin sulfate (CSE) on behavior of retinal growth cones [PDF]

open access: yes, 2013
Chondroitin sulfate (CS), the carbohydrate chain of chondroitin sulfate proteoglycans, is involved in neuronal circuit formation during development. CS shows great structural diversity with combination of disaccharide units of different structure (A-, C-,

Growth cone dynamics during the migration of an identified commissural growth cone [PDF]

open access: yesThe Journal of Neuroscience, 1993
We have used time-lapse video microscopy to study the behavior of a neuron, Q1, that pioneers the posterior commissure of the embryonic grasshopper. Our goal is to use time-lapse video as a tool to acquire a precise picture of normal development over time, and thereby identify stereotypic activities that might indicate important interactions necessary ...

Non-canonical retinoid signaling in neural development, regeneration and synaptic function

open access: yesFrontiers in Molecular Neuroscience
Canonical retinoid signaling via nuclear receptors and gene regulation is critical for the initiation of developmental processes such as cellular differentiation, patterning and neurite outgrowth, but also mediates nerve regeneration and synaptic ...

Performance of Hop Cultivars Grown with Artificial Lighting under Subtropical Conditions

open access: yesPlants, 2023
The objective of this study was to determine the duration of the main phenological stages, plant growth development, yield, and cone quality of hop cultivars grown under artificial light (17 h per day) during vegetative development (early season) in a ...

Directing growth cones of optic axons growing with laser scissors and laser tweezers [PDF]

open access: yes, 2012
We have combined a laser scissors and a laser tweezers to study, (1) the response of nerve fiber growth cones to laserinduced damage on single axons, and (2) localized microfluidic flow generated by laser-driven spinning birefringent particles.

Growth cone-growth cone interactions in cultures of rat sympathetic neurons

open access: yesDevelopmental Biology, 1989
Growth cones of sympathetic neurons from the superior cervical ganglia of neonatal rats were studied using video-microscopy to determine events following contact between growth cones and other cell surfaces, including other growth cones and neurites. A variety of behaviors were observed to occur upon contact between growth cones.

Formation of Ionization-Cone Structures in Active Galactic Nuclei: I. Stationary Model and Linear Stability Analysis [PDF]

open access: yes, 2006
We discuss causes of the formation of the observed kinematics and morphology of cones of ionized matter in the neighborhood of the nuclei of Seyfert galaxies. The results of linear stability analysis of an optically thin conic jet where radiation cooling
