Ammonia Dynamics in the Human Body: Insights in Biomedical Sensing Technologies

open access: yesAdvanced Sensor Research, Volume 4, Issue 7, July 2025.
Ammonia (NH3) is a significant biomarker in diagnostics, affecting the respiratory system, stomach, liver, kidneys, bladder, and gastrointestinal tract. NH3 detection, using sensors, has the potential to improve medical diagnosis. This review examines recent advancements in NH3 sensing technologies and explores future research directions, including ...

Assessment of the Nutraceutical Properties of Wild Strawberry (Fragaria vesca L.) Extracts on Human Colorectal Cell Lines

open access: yesMolecular Nutrition &Food Research, Volume 69, Issue 11, June 2025.
The study explores the nutraceutical potential of wild strawberry (Fragaria vesca L.) by assessing its effects on multiple colorectal carcinoma cell lines. Wild strawberry phytochemicals were able to reduce SW480 cell viability by inducing cell cycle arrest and by promoting programmed cell death in E705 cells, with no toxicity on healthy colorectal ...

Geometric modeling of phase ordering for the isotropic–smectic A phase transition

open access: yesFrontiers in Soft Matter
BackgroundLiquid crystal (LC) mesophases have an orientational and positional order that can be found in both synthetic and biological materials. These orders are maintained until some parameter, mainly the temperature or concentration, is changed ...

3D MR fingerprinting for dynamic contrast‐enhanced imaging of whole mouse brain

open access: yesMagnetic Resonance in Medicine, Volume 93, Issue 1, Page 67-79, January 2025.
Abstract Purpose Quantitative MRI enables direct quantification of contrast agent concentrations in contrast‐enhanced scans. However, the lengthy scan times required by conventional methods are inadequate for tracking contrast agent transport dynamically in mouse brain. We developed a 3D MR fingerprinting (MRF) method for simultaneous T1 and T2 mapping

QRAGE—Simultaneous multiparametric quantitative MRI of water content, T1, T2*, and magnetic susceptibility at ultrahigh field strength

open access: yesMagnetic Resonance in Medicine, Volume 93, Issue 1, Page 228-244, January 2025.
Abstract Purpose To introduce quantitative rapid gradient‐echo (QRAGE), a novel approach for the simultaneous mapping of multiple quantitative MRI parameters, including water content, T1, T2*, and magnetic susceptibility at ultrahigh field strength. Methods QRAGE leverages a newly developed multi‐echo MPnRAGE sequence, facilitating the acquisition of ...

Accelerated 3D metabolite T1 mapping of the brain using variable‐flip‐angle SPICE

open access: yesMagnetic Resonance in Medicine, Volume 92, Issue 4, Page 1310-1322, October 2024.
Abstract Purpose To develop a practical method to enable 3D T1 mapping of brain metabolites. Theory and Methods Due to the high dimensionality of the imaging problem underlying metabolite T1 mapping, measurement of metabolite T1 values has been currently limited to a single voxel or slice.

An analysis of high order FEM and IGA for explicit dynamics: Mass lumping and immersed boundaries

open access: yesInternational Journal for Numerical Methods in Engineering, Volume 125, Issue 16, 30 August 2024.
Summary We investigate the behavior of different shape functions for the discretization of hyperbolic problems. In particular, we consider classical Lagrange polynomials and B‐splines. The studies focus on the performance of the these functions as a spatial discretization approach combined with an explicit time marching scheme.
