A mouse model of mechanical stress injury to the basal ganglia using thermosensitive PNIPAM hydrogel for intracerebral hemorrhage research

open access: yesAnimal Models and Experimental Medicine, EarlyView.
In this study, we established a novel mouse model of intracerebral hemorrhage (ICH) by stereotactically injecting thermosensitive PNIPAM hydrogel into the internal capsule to impose localized mechanical stress on the corticospinal tract, which provides a straightforward and reproducible tool for preclinical studies on focal mechanical stress–induced ...

Functional Polymer‐Engineered Magnetic Nanoparticles as Dual‐Modal Theragnostic Probes for Early Alzheimer's Disease Detection and Therapy

open access: yesAdvanced NanoBiomed Research, EarlyView.
The nanoparticle consists of a 3 nm iron oxide core functionalized with an amphiphilic polymer coating containing Aβ‐targeting DSA moieties and biocompatible PEG chains. This design supports measurable transport in a BBB‐related model and specific interaction with Aβ species, while providing MRI contrast enhancement for diagnosis and therapeutic ...

Scaffold‐Free Living Cellular Structure With Omnidirectional Architectures

open access: yesAdvanced NanoBiomed Research, EarlyView.
Hydrogel lumen confinement enables the direct formation of mechanically stable, scaffold‐free cellular filaments under entirely aqueous, phototoxicity‐free conditions. These processable living building blocks support omnidirectional assembly into complex three‐dimensional architectures, providing a simple and versatile platform for scaffold‐free ...

In Vivo Nb4C3Tx MXene‐Assisted Photothermal Therapy of Melanoma in Mice

open access: yesAdvanced NanoBiomed Research, EarlyView.
Nb4C3Tx MXene converts pulsed 1064 nm irradiation into localized heat, producing concentration‐ and time‐dependent melanoma cell killing in vitro and suppressing tumor growth in mice. Histology reveals extensive tumor damage, macrophage‐associated material clearance, and no detectable persistent deposits in examined visceral organs, supporting Nb4C3Tx ...

Modifications of Lysine Residues 294 and 311 Within the Microtubule‐Binding Region Alter Tau Aggregation and Tubulin Binding Equilibria

open access: yesAngewandte Chemie, EarlyView.
The molecular consequences of specific lysine modifications in Alzheimer´s disease remain insufficiently resolved in the context of full‐length protein. Here we integrate protein semisynthesis, segmental isotope labelling, and high‐resolution NMR spectroscopy to achieve residue‐resolved interrogation of site‐specific acetylation and carboxymethylation.

Supramolecular Assembly of an Antimicrobial Peptide Into a Pore

open access: yesAngewandte Chemie, EarlyView.
Supramolecular assembly of an AMP is linked to transport across the Staphylococcus aureus membrane. ABSTRACT Antimicrobial peptides (AMPs) have long been ascribed the ability to form pores. These structures, some observed, others inferred, vary in their mechanisms of action, though most are associated with lysis.

Light sheet fluorescence microscopy

Nature Reviews Methods Primers, 2021
Light sheet fluorescence microscopy (LSFM) uses a thin sheet of light to excite only fluorophores within the focal volume. Light sheet microscopes (LSMs) have a true optical sectioning capability and, hence, provide axial resolution, restrict photobleaching and phototoxicity to a fraction of the sample and use cameras to record tens to thousands of ...

3D Volume Rendering of Invertebrates Using Light-Sheet Fluorescence Microscopy

open access: yesPhotonics, 2022
Light-Sheet Fluorescence Microscopy has recently emerged as the technique of choice for obtaining high quality three-dimensional (3D) images of whole organisms, with low photo-damage and fast acquisition rates.

Practical considerations for quantitative light sheet fluorescence microscopy

Nature Methods, 2022
Fluorescence microscopy has evolved from a purely observational tool to a platform for quantitative, hypothesis-driven research. As such, the demand for faster and less phototoxic imaging modalities has spurred a rapid growth in light sheet fluorescence microscopy (LSFM).

Nonlinear light-sheet fluorescence microscopy by photobleaching imprinting [PDF]

open access: yesJournal of the Royal Society Interface, 2014
Abstract We present a nonlinear light-sheet fluorescence microscopy (LSFM) scheme based on photobleaching imprinting. By measuring photobleaching-induced fluorescence decay, our method simultaneously achieves a large imaging field of view and a thin optical section.
