Calcium Imaging in Neuron Cell Death [PDF]

open access: yes, 2014
Intracellular Ca2+ is involved in control of a large variety of cell functions including apoptosis and neuron cell death. For example, intracellular Ca2+ overload is critical in neuron cell death induced by excitotoxicity. Thus, single cell monitoring of intracellular Ca2+ concentration ([Ca2+]cyt ) in neurons concurrently with apoptosis and neuron ...

A turquoise fluorescence lifetime-based biosensor for quantitative imaging of intracellular calcium

open access: yesNature Communications, 2021
Currently, genetically encoded calcium indicators are not suitable for direct quantification. Here the authors engineer a fluorescence lifetime imaging calcium biosensor, Turquoise Calcium Fluorescence LIfeTime Sensor (Tq-Ca-FLITS), and measure ...

Hierarchy of neural organization in the embryonic spinal cord: Granger-causality graph analysis of in vivo calcium imaging data

open access: yes, 2014
The recent development of genetically encoded calcium indicators enables monitoring in vivo the activity of neuronal populations. Most analysis of these calcium transients relies on linear regression analysis based on the sensory stimulus applied or the ...

Fast Calcium Imaging with Optical Sectioning via HiLo Microscopy.

open access: yesPLoS ONE, 2015
Imaging intracellular calcium concentration via reporters that change their fluorescence properties upon binding of calcium, referred to as calcium imaging, has revolutionized our way to probe neuronal activity non-invasively.

Estimating firing rates from calcium signals in locust projection neurons in vivo

open access: yesFrontiers in Neural Circuits, 2007
Combining intracellular electrophysiology and multi-photon calcium imaging in vivo, we studied the relationship between calcium signals (sampled at 500-750 Hz) and spike output in principal neurons in the locust antennal lobe.

IP3 mediated global Ca2+ signals arise through two temporally and spatially distinct modes of Ca2+ release

open access: yeseLife, 2020
The ‘building-block’ model of inositol trisphosphate (IP3)-mediated Ca2+ liberation posits that cell-wide cytosolic Ca2+ signals arise through coordinated activation of localized Ca2+ puffs generated by stationary clusters of IP3 receptors (IP3Rs). Here,

CaPTure: Calcium PeakToolbox for analysis of in vitro calcium imaging data

open access: yesBMC Neuroscience, 2022
Background Calcium imaging is a powerful technique for recording cellular activity across large populations of neurons. However, analysis methods capable of single-cell resolution in cultured neurons, especially for cultures derived from human induced ...

Detection of multivessel calcific disease progression in a patient with chronic limb-threatening ischemia using fluorine-18 sodium fluoride positron emission tomography imaging

open access: yesJournal of Vascular Surgery Cases and Innovative Techniques, 2023
Vascular calcification contributes to morbidity and poor clinical outcomes for patients with peripheral artery disease; however, the traditional assessment of the calcium burden using computed tomography (CT) imaging or angiography represents already ...

Continuous volumetric imaging via an optical phase-locked ultrasound lens

open access: yes, 2016
In vivo imaging at high spatiotemporal resolution is key to the understanding of complex biological systems. We integrated an optical phase-locked ultrasound lens into a two-photon fluorescence microscope and achieved microsecond-scale axial scanning ...
