Hydrogel platforms for 3D cardiac tissue engineering and fibrotic disease modelling

FEBS Open Bio, EarlyView.
Hydrogel‐based cardiac tissue models are advancing our understanding of heart health and disease. By incorporating electrical conductivity, aligned structures, and tunable mechanical properties, these platforms better replicate the complex environment of native heart tissue.

Engineering-Constrained Mixed-Encoding Genetic Algorithm Optimization of Bias Coils for Cold Atom Gravimeters

Applied Sciences
The sensitivity of cold atom gravimeters is strongly governed by the spatial uniformity of their internal bias magnetic field. This paper presents an engineering-constrained optimization framework based on a mixed-encoding genetic algorithm for designing

Neurochemical Endpoints to Inform Early‐Stage Trials of Spinocerebellar Ataxia 2 and 3 in a Multisite Setting

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Neurochemical levels measured by brain MR spectroscopy (MRS) have been proposed as endpoints for clinical trials in early‐stage spinocerebellar ataxia (SCA) trials. We tested their trial‐readiness by quantifying neurochemicals in three affected brain regions in early‐stage cohorts of SCA2 and SCA3, examining their reproducibility in ...

Magnetic Gradient edge magnetoplasmons in non-uniform magnetic field [PDF]

, 2012
We have theoretically studied two-dimensional electron gas placed in a strong laterally non-uniform magnetic field, which appears due to ferromagnetic film . We have found, that in this case 2DEG experiences static charge redistribution that strongly

Upper Cervical Cord Area as a Biomarker of Conversion to Secondary Progressive Multiple Sclerosis

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective This study assessed whether upper cervical cord area (UCCA) measured on routine brain MRI can serve as a biomarker of conversion to SPMS. Methods This is a single‐center retrospective cohort study of RRMS patients with cross‐sectional and longitudinal analyses of clinical and MRI data. Future SPMS converters were matched by age, sex,

An Optimal Design of an Electromagnetic Actuation System towards a Large Homogeneous Magnetic Field and Accessible Workspace for Magnetic Manipulation

Energies, 2020
Untethered nano-/microrobots have been appealing to biomedical applications under magnetic guidance. Numerous actuation systems are specifically designed to generate either uniform or non-uniform fields which are unable to support all actuating ...

Four‐Year Cognitive Outcomes in Multiple Sclerosis: Associations With Lesion Myelin Integrity

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objectives Cognitive impairment is prevalent in patients with multiple sclerosis (MS) but whether lesion myelin integrity influences future cognitive outcomes remains unclear. We investigated the relationship between baseline lesion myelin water fraction (MWF) and cognitive performance 4 years later.

THERMOMAGNETIC CONVECTION OF FERROFLUID IN NON-UNIFORM MAGNETIC FIELD ARROUND A CURRENT CARRYING WIRE

, 2017
In this paper, the induced thermomagnetic convection of a dilute ferrofluid in a non-uniform magnetic field induced around a current-carrying wire was theoretically studied, experimentally tested and numerically validated. The temperature rise of the hot
