In-vivo digital wavefront sensing using swept source OCT

Biomedical Optics Express, 2017
Sub-aperture based digital adaptive optics is demonstrated in a fiber based point scanning optical coherence tomography system using a 1060 nm swept source laser. To detect optical aberrations in-vivo, a small lateral field of view of ~[Formula: see text] is scanned on the sample at a high volume rate of 17 Hz (~1.3 kHz B-scan rate) to avoid any ...

Exploring the Fragmentation of Sodiated Species Involving Covalent‐Bond Cleavages for Metabolite Characterization

Rapid Communications in Mass Spectrometry, EarlyView.
ABSTRACT Rationale Electrospray (ESI), the most popular desorption/ionization technique used in mass spectrometry‐based metabolomics, generates both protonated and deprotonated molecules, as well as adduct ions, sodium being the most frequent monoatomic cation entering their composition.

Swept-source OCT in patients with multiple evanescent white dot syndrome

Journal of Ophthalmic Inflammation and Infection, 2018
Background Swept-source optical coherence tomography (SS-OCT) has a higher scanning rate and longer wavelength in comparison with spectral-domain OCT (SD-OCT), allowing an improved imaging of retinal vascular plexuses and choriocapillaris.

Depth-encoded all-fiber swept source polarization sensitive OCT

Biomedical Optics Express, 2014
Polarization sensitive optical coherence tomography (PS-OCT) is a functional extension of conventional OCT and can assess depth-resolved tissue birefringence in addition to intensity. Most existing PS-OCT systems are relatively complex and their clinical translation remains difficult.

Step‐Ladder Bioprinting to Align Collagen Fibers for Anisotropic Tissue Fabrication

Small, EarlyView.
The step‐ladder printing platform includes successive segments of channels with varying widths in a custom barrel design. This design allows for improved anisotropy of collagen fibers during extrusion. To demonstrate its effectiveness, corneal constructs with high transparency and shape fidelity, as well as articular cartilage constructs, displaying ...

Revolutionising Glaucoma Care with Optical Coherence Tomography: A New Horizon

TNOA Journal of Ophthalmic Science and Research
Optical coherence tomography (OCT) has become a commonly utilised imaging modality in the detection and monitoring of structural glaucomatous damage. OCT has undergone several evolutionary phases, advancing from time-domain OCT, through spectral-domain ...

Renovating Neural Networks With Viral‐Mediated Gene Transfer From A Tissue Contacting Matrix Mimic

Small, EarlyView.
Fmoc‐DDIKVAV self‐assembling peptidemediated delivery of AAV‐BDNF significantly enhances neuroprotection in the striatum of a mouse model compared with AAV‐BDNF injection alone. This synergistic integration of biomaterial scaffolding and gene therapy holds substantial promise for slowing the progression of neurodegenerative diseases such as Huntington ...

Thermo‐Chemically Modified Silk Scaffolds Reveal Niche‐Driven Regulation of Hematopoiesis and Fibrosis

Small, EarlyView.
We introduce a versatile 3D platform that recreates key physical and biological features of the human bone marrow. By integrating tunable silk biomaterials, stromal cells, and human hematopoietic progenitors, the model captures both healthy and diseased microenvironments, analysis of blood formation, and its disruption in pathological conditions ...
