Comparative Study of Gas and Liquid Flow in Packed Beds Using Phase‐Contrast MRI

Chemie Ingenieur Technik, EarlyView.
This work presents applications of phase‐contrast magnetic resonance imaging (MRI) to investigate fluid flow fields and temperature in packed beds. Comparison of ethane (C2H6) gas flow with that of water flow is done at similar flow conditions. The temperature of water is also measured using MRI.

Prevalence of transthyretin cardiac amyloidosis in undifferentiated heart failure with preserved ejection fraction

ESC Heart Failure, Volume 12, Issue 2, Page 1176-1182, April 2025.
Abstract Aims Transthyretin amyloid cardiomyopathy (ATTR‐CM) is an increasinglyrecognized cause of heart failure with preserved ejection fraction (HFpEF), which may be diagnosed non‐invasively using 99mTc 3,3‐diphosphono‐1,2‐propanodicarboxylic acid (DPD) scintigraphy‐based diagnostic criteria.

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

ESC 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

Venous blood lactate concentration as a predictor of intestinal viability in horses with acquired indirect inguinal hernia

Equine Veterinary Journal, EarlyView.
Abstract Background Acquired indirect inguinal hernia represents a life‐threatening emergency. Therapeutic decision‐making largely depends on intestinal viability, for which specific predictive parameters (such as venous lactate) have not been evaluated.

Pulsed wave tissue Doppler imaging of the left ventricle in foals: Feasibility, inter‐ and intra‐observer variability and wave pattern over the first days of life

Equine Veterinary Journal, EarlyView.
Abstract Background Tissue Doppler imaging (TDI) may improve the assessment of myocardial function in neonatal foals. Objectives To document the feasibility of left ventricular pulsed wave (PW) TDI, inter‐ and intra‐observer variability and wave pattern over the first 5 days of life. Study Design Prospective observational study.

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

FlexMat, 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 ...

Vascular Testing to Overcome Anatomical Contraindication: Fibula Free Flap in Bilateral Peronea Arteria Magna

Head &Neck, EarlyView.
ABSTRACT Background Peronea arteria magna (PAM) is an established contraindication for fibula free flap due to concern for vascular compromise of the lower leg. Methods This is a case of a 74‐year‐old male with a history of multiply recurrent oral cavity cancer who had undergone prior free flap reconstruction who presented with a new oral cavity ...
