Cluster and Kill: the Use of Clustering‐Triggered Emission Materials for Singlet Oxygen Photosensitization in Antimicrobial Photodynamic Therapy

Advanced Optical Materials, Volume 13, Issue 3, January 24, 2025.
Photosensitizers are one of the agents, together with oxygen and light, necessary for performing antimicrobial photodynamic therapy. Aggregation of those polymers is usually undesirable, however taking advantage of aggregated induced emission occurring in Clustering‐Triggered Emission (CTE) materials, hampers singlet oxygen formation which can be aimed

Nanoscale Operando Characterization of Electrolyte‐Gated Organic Field‐Effect Transistors Reveals Charge Transport Bottlenecks

Advanced Materials, Volume 36, Issue 13, March 28, 2024.
This study delves into the charge transport properties of electrolyte‐gated organic field‐effect transistors by employing in‐liquid scanning dielectric microscopy. By introducing a novel interpretation framework, the research achieves quantitative mapping of the local electric potential, facilitating a detailed assessment of charge transport ...

Rationally designed azobenzene photoswitches for efficient two-photon neuronal excitation

Nature Communications, 2019
Two-photon absorption capacity of azobenzene photoswitches usually comes with a reduction in thermal stability. Here, the authors developed photoswitches with high two-photon sensitivity and enhanced cis isomer thermal lifetime for the control of ...

Alzheimer’s Disease Mutant Mice Exhibit Reduced Brain Tissue Stiffness Compared to Wild-type Mice in both Normoxia and following Intermittent Hypoxia Mimicking Sleep Apnea

Frontiers in Neurology, 2018
BackgroundEvidence from patients and animal models suggests that obstructive sleep apnea (OSA) may increase the risk of Alzheimer’s disease (AD) and that AD is associated with reduced brain tissue stiffness.AimTo investigate whether intermittent hypoxia (

Opposing roles for ADAMTS2 and ADAMTS14 in myofibroblast differentiation and function

The Journal of Pathology, Volume 262, Issue 1, Page 90-104, January 2024.
Abstract Crosstalk between cancer and stellate cells is pivotal in pancreatic cancer, resulting in differentiation of stellate cells into myofibroblasts that drives tumour progression. To assess cooperative mechanisms in a 3D context, we generated chimeric spheroids using human and mouse cancer and stellate cells. Species‐specific deconvolution of bulk‐

Hha has a defined regulatory role that is not dependent upon H-NS or StpA

Frontiers in Microbiology, 2015
The Hha family of proteins is involved in the regulation of gene expression in enterobacteria by forming complexes with H-NS-like proteins. Whereas several amino acid residues of both proteins participate in the interaction, some of them play a key role.

Formation of an invasion-permissive matrix requires TGFβ/SNAIL1-regulated alternative splicing of fibronectin

Breast Cancer Research, 2023
Background As in most solid cancers, the emergence of cells with oncogenic mutations in the mammary epithelium alters the tissue homeostasis. Some soluble factors, such as TGFβ, potently modify the behavior of healthy stromal cells.
