Three-dimensional virtual refocusing of fluorescence microscopy images using deep learning

, 2019
Three-dimensional (3D) fluorescence microscopy in general requires axial scanning to capture images of a sample at different planes. Here we demonstrate that a deep convolutional neural network can be trained to virtually refocus a 2D fluorescence image ...

Simultaneous submicrometric 3D imaging of the micro-vascular network and the neuronal system in a mouse spinal cord [PDF]

, 2014
Defaults in vascular (VN) and neuronal networks of spinal cord are responsible for serious neurodegenerative pathologies. Because of inadequate investigation tools, the lacking knowledge of the complete fine structure of VN and neuronal systems is a ...

Structural biology of ferritin nanocages

FEBS Letters, EarlyView.
Ferritin is a conserved iron‐storage protein that sequesters iron as a ferric mineral core within a nanocage, protecting cells from oxidative damage and maintaining iron homeostasis. This review discusses ferritin biology, structure, and function, and highlights recent cryo‐EM studies revealing mechanisms of ferritinophagy, cellular iron uptake, and ...

Three-Dimensional Imaging in Orthodontics

Turkish Journal of Orthodontics, 2018
Orthodontic records are one of the main milestones in orthodontic therapy. Records are essential not only for diagnosis and treatment planning but also for follow-up of the case, communicating with colleagues, and evaluating the treatment outcomes ...

Reconstruction and physical fit analysis of fragmented skeletal remains using 3D imaging and printing

Forensic Science International: Reports, 2020
Physical fit analysis (PFA) entails physically fitting fragmented evidence together to determine shared origin. PFA can be challenging to conduct with bone fragments particularly when fragile, sharp, or embedded in other materials. Three-dimensional (3D)

3D elemental imaging of the crustacean Ceriodaphnia by means of SR confocal micro-XRF [PDF]

, 2011
Daphnia is a freshwater crustacean (0.2-5 mm height) used for investigating the toxic effects of toxins (e.g. metals) on an ecosystem. Synchrotron radiation based micro X-ray fluorescence (SR micro-XRF) allows the investigation of the trace level metal ...

The utility of the 3D imaging software in the macroscopic rendering of complex gynecologic specimens [PDF]

, 2015
A new generation of three dimensional (3D) imaging software for the anatomical rendering of the human body, and related surgical pathologies, is postulated.

The planar cell polarity protein Vangl2 interacts with the PDZ‐domains of Scribble but not with a unique PDZ‐like domain in Inturned

FEBS Letters, EarlyView.
Structural and biochemical characterisations show that the planar cell polarity (PCP) protein Inturned harbours a unique PDZ‐like domain that does not bind canonical PDZ‐binding motifs (PBMs) like that of another PCP protein Vangl2. In contrast, the apical‐basal polarity protein Scribble contains four PDZ domains that bind Vangl2, but one PDZ domain ...

Quantitative volumetric Raman imaging of three dimensional cell cultures [PDF]

, 2017
The ability to simultaneously image multiple biomolecules in biologically relevant three-dimensional (3D) cell culture environments would contribute greatly to the understanding of complex cellular mechanisms and cell-material interactions.

Cytoplasmic p21 promotes stemness of colon cancer cells via activation of the NFκB pathway

Molecular Oncology, EarlyView.
Cytoplasmic p21 promotes colorectal cancer stem cell (CSC) features by destabilizing the NFκB–IκB complex, activating NFκB signaling, and upregulating BCL‐xL and COX2. In contrast to nuclear p21, cytoplasmic p21 enhances spheroid formation and stemness transcription factor CD133.
