Left atrial function in uraemic patients: Four‐dimensional automatic left atrial quantitative technology study

open access: yesESC Heart Failure, Volume 12, Issue 2, Page 1316-1325, April 2025.
Abstract Objective This study aimed to evaluate the utility of left atrial volume and function in uraemic patients using four‐dimensional automatic left atrial quantification (4D auto LAQ) technology. Methods Thirty‐four undialysed uraemic patients (U‐ND group), 60 dialysed uraemic patients (U‐D group), and 32 healthy volunteers (N group) were enrolled

Trendelenburg positioning with or without norepinephrine infusion for haemodynamic support in anaesthetised hypovolemic horses

open access: yesEquine Veterinary Journal, EarlyView.
Abstract Background Intraoperative haemorrhage during equine anaesthesia is a rare but potentially fatal complication requiring prompt haemodynamic support. Postural manoeuvres such as Trendelenburg (TL) positioning and vasopressor support augment venous return and improve cardiac output (CO), yet their efficacy in anaesthetised hypovolemic horses ...

Agreement between invasive and oscillometric blood pressure measurements during controlled haemorrhage in anaesthetised horses

open access: yesEquine Veterinary Journal, EarlyView.
Abstract Background Defining the reliability of oscillometry (NIBP) for measuring mean arterial pressure (MAP) during normotension and hypovolaemic hypotension could help with cardiovascular monitoring and management in horses anaesthetised in dorsal recumbency.

Flexible wearable electronics for cardiovascular monitoring from surface signals to deep physiological insights

open access: yesFlexMat, EarlyView.
This review organizes flexible wearable electronics for cardiovascular monitoring into four interconnected information layers: surface electrophysiology, hemodynamic sensing, vascular imaging, and biofluid biomarker analysis. This framework clarifies how electrical rhythm, vascular loading, structural and flow‐related features, and biochemical states ...

Association Between MRI‐Derived Right‐to‐Left Ventricular Volume Ratio and Regional Left Ventricular Myocardial Dysfunction in Patients With Pulmonary Arterial Hypertension

open access: yesJournal of Magnetic Resonance Imaging, EarlyView.
ABSTRACT Background Right ventricular (RV) to left ventricular (LV) end‐diastolic volume ratio (RV/LV) is a validated marker of RV dilation in pulmonary arterial hypertension (PAH), yet its impact on LV myocardial function and the underlying mediating pathway is incompletely characterized.

Effect of sonication on European and Peruvian lupin flours: impact on the technological quality of gluten‐free breads and as a partial substitute for wheat

open access: yesJournal of the Science of Food and Agriculture, EarlyView.
Abstract BACKGROUND A widely cultivated pulse, lupin, has garnered interest for its beneficial nutritional properties, especially for baking applications. The harmful alkaloid content and poor functional properties of lupin limit its wider use. Sonication is an ecofriendly technology used to modify molecular structures.

Knee joint line obliquity alters lateral meniscal root tension, tibiofemoral subluxation and compartment‐specific contact pressures

open access: yesKnee Surgery, Sports Traumatology, Arthroscopy, EarlyView.
Abstract Purpose The objective was to measure effects of joint line obliquity (JLO) on meniscus posterior root tension, tibiofemoral subluxation and contact pressures. It was hypothesised that a medial JLO would increase medial meniscal (MM) root tension, medial tibiofemoral subluxation and medial compartment contact pressure, and vice versa for ...

Thermoresponsive Gel‐Yarn Composites Enable Low‐Temperature Tensile Actuation in Twisted and Coiled Polymer Artificial Muscles

open access: yesMacromolecular Rapid Communications, EarlyView.
Thermoresponsive gel–yarn composites integrate poly(MAA‐co‐OEGMA) hydrogels with twisted and coiled polyester yarns to enable reversible tensile actuation between 25°C and 50°C. Hydrogel swelling and deswelling generate internal stresses that drive lengthwise actuation, achieving isotonic strains up to 39%.

Dynamic Analysis of Electrically Assisted Turbocharger Rotor Considering Contact Effects in Nut Structures

open access: yesInternational Journal of Mechanical System Dynamics, EarlyView.
ABSTRACT The rotor system of an electrically assisted turbocharger (EAT) is composed of multiple shaft components; The nonlinear connection and contact effects make it difficult to determine the system dynamic characteristics. To improve the modeling accuracy of EAT rotor system and evaluate the influence of contact between multi‐axis components and ...
