Advancing collagen‐related pathology assessment through second‐harmonic generation imaging

Journal of Microscopy, EarlyView.
Abstract Collagen remodelling and dysregulation are the hallmarks of diverse pathological conditions. In this context, second‐harmonic generation (SHG) imaging has emerged as a powerful label‐free modality for assessing collagen. This offers submicron resolution, intrinsic optical sectioning, and deeper imaging capabilities without the need for ...

Chronic silencing of subsets of cortical layer 5 pyramidal neurons has a long‐term influence on the laminar distribution of parvalbumin interneurons and the perineuronal nets

Journal of Anatomy, Volume 246, Issue 4, Page 479-504, April 2025.
Chronic silencing of subsets of layer 5 projection neurons has distinct effects on the laminar distribution of PV interneurons and the perineuronal nets in the adult primary motor and somatosensory cortex. Abstract Neural networks are established throughout cortical development, which require the right ratios of glutamatergic and GABAergic neurons ...

The tympanic covering layer contributes to basilar membrane elasticity potentially influencing human frequency resolution and speech perception

Journal of Anatomy, EarlyView.
In this study we show for the first time that the human basilar membrane contains elastin produced by the so‐called tympanic covering layer. It is believed to play an important functional role in human cochlear tuning, particularly low frequencies linked to our remarkable speech and music perception.

Reconstruction of native cellular microanatomy in a novel bioengineered full thickness human nasal mucosal construct

Journal of Anatomy, EarlyView.
Bioengineered tissue constructs are vital technologies employed in in vitro testing of both fundamental biological principles and industrial screening practices. Current approaches to modelling the nasal mucosa in vitro are not representative and are associated with limitations that impact their reliability and predictive value.

Influence of nanohydroxyapatite mouthwash on the growth of Candida albicans biofilm on milled denture surfaces: An in vitro study

Journal of Prosthodontics, EarlyView.
Abstract Purpose There is a need for effective solutions for the persistent prevalence of denture stomatitis (DS) in denture‐wearing populations. This study assessed the impact of nanohydroxyapatite (nanoHAP) nanoparticles on Candida albicans biofilm formation on milled polymethylmethacrylate (PMMA) denture bases.

Novel Hydrurus species (Chrysophyceae) and their adaptations to high‐altitude European and Arctic snowfields

Journal of Phycology, EarlyView.
Abstract Colored snow caused by green algae (Chlorophyceae) is well known, but melting snowpacks can also harbor golden‐brown blooms consisting of Chrysophyceae. We collected 14 samples of cryoflora in the Austrian and Swiss Alps, the High Tatras in Slovakia, and in Arctic Svalbard. Eight laboratory unicellular flagellated strains were established from
