Lithium-loaded GelMA-Phosphate glass fibre constructs: Implications for astrocyte response
This study was also aimed at investigating the effects of lithium-loaded GelMA-PGFs hydrogels in alleviating astrocyte reactivity and glial scar formation offering novel perspectives for neural tissue engineering applications. The rationale behind introducing lithium is driven by its long-proven therapeutic benefits in mental disorders, and neuroprotective and pronounced anti-inflammatory properties. The optimal concentrations of lithium and LPS were determined in vitro on primary rat astrocytes. Furthermore, qPCR was conducted for gene expression analysis of GFAP and IL-6 markers on primary astrocytes cultured 3D into Gel...

The primate corticospinal system has a widespread cortical origin and an extensive range of different fibre diameters, including thick, fast-conducting axons. Direct cortico-motoneuronal (CM) projections from the motor cortex to arm and hand alpha motoneurons are a recent evolutiona...

A combined analytical and Monte Carlo method for detailed simulations of antiscatter grids in x-ray medical imaging: implementing scatter within the grid
Phys Med Biol. 2024 Feb 21. doi: 10.1088/1361-6560/ad2b93. Online ahead of print.ABSTRACTTo implement a hybrid method, which combines analytical tracking and interaction simulation using Monte Carlo (MC) techniques, in order to model photon transport inside antiscatter grids (ASG) for x-ray imaging.
Approach: A new tally was developed for PENELOPE (v.2018) and penEasy (v. 2020) MC code to simulate photon transmission through ASGs. Two established analytical algorithms from the literature were implemented in this tally. In addition, new hybrid method was introduced by extending one of the analytical algorithms to in...

Quantitation of circulating short-chain fatty acids in small volume blood samples from animals and humans
Talanta. 2024 Feb 3;272:125743. doi: 10.1016/j.talanta.2024.125743. Online ahead of print.ABSTRACTBACKGROUND: The role of gut microbiota in human health has been intensively studied and more recently shifted from emphasis on composition towards function. Function is partly mediated through formed metabolites. Short-chain fatty acids (SCFAs) such as acetate, propionate, and butyrate as well as their branched analogues represent major products from gut fermentation of dietary fibre and proteins, respectively. Robust and high-throughput analysis of SCFAs in small volume blood samples have proven difficult. Major obstacles com...

Influence of choroidal microvasculature dropout on progressive retinal nerve fibre layer thinning in primary open-angle glaucoma: comparison of parapapillary {beta}-zones and {gamma}-zones
Conclusions The presence of cMvD was significantly associated with a faster rate of RNFL thinning in POAG eyes with β-zone, but not -zone. The pathogenic consequences of cMvD in POAG eyes may depend on accompanying peripapillary structures. (Source: British Journal of Ophthalmology)
