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 ...

Arterial Perivascular Space‐Mediated Solute Transport in the Mouse Brain

open access: yesExploration, EarlyView.
The mechanisms underlying solute clearance from the brain parenchyma remain debated, with competing hypotheses involving bulk cerebrospinal fluid flow versus perivascular transport. Using multimodal in vivo imaging and computational modeling in mice, this study demonstrates that arterial pulsation drives bidirectional solute movement within the ...

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 ...

Anisotropic Initial Damage and Its Effect on Tensile Response of Plain Concrete

open access: yesInternational Journal for Numerical and Analytical Methods in Geomechanics, EarlyView.
ABSTRACT Damage is often described as isotropic, implying that a scalar value describes its initial state. However, the prior micro‐cracking pattern at points of an existing building, that is, the initial damage, may be oriented by a preload. The degradation of the Volume Element due to oriented preloads shall be described as anisotropic and ...

Neuromuscular Monitoring of Rocuronium 0.6 mg/kg in Children Aged 3–24 Months With Electromyography and Acceleromyography: An Observational Study

open access: yesPediatric Anesthesia, EarlyView.
ABSTRACT Background Objective neuromuscular monitoring is essential to prevent residual neuromuscular block in patients receiving neuromuscular blocking agents. However, the small size of pediatric hands and the lack of appropriately sized neuromuscular equipment have made quantitative neuromuscular monitoring at the ulnar nerve (UN) difficult. In such

Nonwoven rCF/PA6 Thermoplastic Composites: Hybrid Commingled Fibers vs. Powder Impregnation—Effects on Microstructure and Mechanical Properties

open access: yesPolymer Composites, EarlyView.
Comparison of powder impregnation and hybrid commingled non‐wovens for PA6/rCF nonwoven composites. The two‐step powder route gives lower voids and higher properties, while the single‐step hybrid route is limited by precursor inhomogeneity and high void content.

Predictive Assessment of Progressive Damage in Mechanically Fastened Glass–Epoxy Composites

open access: yesPolymer Composites, EarlyView.
Progressive damage in mechanically fastened glass–epoxy composites. ABSTRACT Ensuring the structural integrity of advanced composites necessitates precise methodologies for forecasting the onset and progression of damage. This research focused on the predicting progressive damage (PD) for riveted joints composite laminates employing a combined ...
