Matching model with mechanism: Appropriate rodent models for studying various aspects of diabetes pathophysiology.

Methods Cell Biol

January 2025

School of Cardiovascular and Metabolic Medicine & Sciences, King's College London, London, United Kingdom. Electronic address:

Many rodent models are available for preclinical diabetes research making it a challenge for researchers to choose the most appropriate one for their experimental question. To aid in this, models have classically been categorized according to which type of diabetes they represent, and further into whether the model is induced, spontaneous or the result of genetic manipulation. This fails to capture the complexity of pathogenesis seen in diabetes in humans.

Diabetes and Endocrinology, Birmingham Women's and Children's NHS Foundation Trust, Birmingham, UK

Introduction: The UK national pediatric diabetes audit reports higher HbA1c for children and young people (CYP) with type 1 diabetes (T1D) of Black ethnicity compared with White counterparts. This is presumably related to higher mean blood glucose (MBG) due to lower socioeconomic status (SES) and less access to technology. We aimed to determine if HbA1c ethnic disparity persists after accounting for the above variables.

Atrial fibrillation versus. atrial myopathy in thrombogenesis: Two sides of the same coin?

Trends Cardiovasc Med

January 2025

Liverpool Centre for Cardiovascular Science at University of Liverpool, Liverpool John Moores University and Liverpool Heart and Chest Hospital, Liverpool, United Kingdom; Department of Clinical Medicine, Aalborg University, Aalborg, Denmark; Medical University of Bialystok, Bialystok, Poland.

Atrial fibrillation (AF) and atrial myopathy are recognized contributors to cardiovascular morbidity, particularly ischemic stroke. AF poses an elevated risk of thrombogenesis due to irregular heart rhythm leading to blood stasis and clot formation. Atrial myopathy, marked by structural and functional alterations in the atria, is emerging as a crucial factor influencing thromboembolic events, independently of AF.

Challenges and compromises: Predicting unbound antibody structures with deep learning.

Curr Opin Struct Biol

January 2025

Oxford Protein Informatics Group, Department of Statistics, University of Oxford, 24-29 St Giles', Oxford, OX1 3LB, United Kingdom.

Therapeutic antibodies are manufactured, stored and administered in the free state; this makes understanding the unbound form key to designing and improving development pipelines. Prediction of unbound antibodies is challenging, specifically modelling of the CDRH3 loop, where inaccuracies are potentially worse due to a bias in structural data towards antibody-antigen complexes. This class imbalance provides a challenge for deep learning models trained on this data, potentially limiting generalisation to unbound forms.

Simulation of the performance of pillar array columns using the pore-throat ratio as efficiency descriptor.

J Chromatogr A

January 2025

Institute for Bioengineering, School of Engineering, The University of Edinburgh, Edinburgh, EH9 3BF, United Kingdom.

Traditional packed beds in chromatography suffer from increased band broadening due to the random nature of packing, leading non-ideal fluid flow and channeling. To address these challenges, pillar array columns have been developed, offering improved performance over random packing thanks to their homogenous fluid profiles. The study aims to i) evaluate fluid dynamics and chromatographic performance across different PAC morphologies, ii) establish the influence of column morphology on performance, and iii) assess the correlation between chromatographic performance and hydrodynamic parameters.

Reducing bias in source-free unsupervised domain adaptation for regression.

Neural Netw

January 2025

Luca Healthcare R&D, Shanghai, 200000, China. Electronic address:

Due to data privacy and storage concerns, Source-Free Unsupervised Domain Adaptation (SFUDA) focuses on improving an unlabelled target domain by leveraging a pre-trained source model without access to source data. While existing studies attempt to train target models by mitigating biases induced by noisy pseudo labels, they often lack theoretical guarantees for fully reducing biases and have predominantly addressed classification tasks rather than regression ones. To address these gaps, our analysis delves into the generalisation error bound of the target model, aiming to understand the intrinsic limitations of pseudo-label-based SFUDA methods.
