Double Helix Structure for Stable Flexural Actuation in Soft Robotics

Advanced Intelligent Systems, EarlyView.
This work introduces a double‐helical architecture for soft robotic actuators that enhances twisting resistance, increases output force, and minimizes undesired deformation. Actuators driven by shape‐memory alloy wires exhibit a roughly fivefold higher torsional/flexural stiffness ratio and 50% greater force output.

Experimental analysis and optimization of the variable valve timing on attaining high efficiency with low NOx emission of a direct-injected hydrogen engine

Fuel
The direct-injection hydrogen engine (DI-H2ICE) has demonstrated zero carbon emissions with high brake thermal efficiencies (BTE). Due to the high stoichiometric air–fuel ratio of hydrogen, with a lean burn strategy the gas exchange process of a hydrogen engine is different to a gasoline engine, and the valve timing controlling strategy requires ...

Small‐Scale Magnetic Peristaltic Soft Robot With Mobility and Transport Capabilities

Advanced Intelligent Systems, EarlyView.
This study introduces a miniature, untethered soft magnetic microrobot with peristaltic capabilities for both locomotion and cargo transport. Eight helically magnetized elastomeric strips deform under rotating fields (10–80 mT, 1–5 Hz), enabling movement across rods and lumina at up to 4.1 body lengths min‐¹.

Design and Characterization of a Dual‐Mode Soft Robotic Flapping Propeller With Pneumatic Stiffness Modulation

Advanced Intelligent Systems, EarlyView.
A novel soft robotic propeller overcomes traditional efficiency‐flexibility tradeoffs via a hybrid pneumatic‐cable actuation strategy. This architecture enables active stiffness modulation with dual‐mode locomotion: tunable biomimetic swimming and earthworm‐inspired wriggling for confined spaces.

Lymphatic Abnormalities in Noonan Syndrome Extend Beyond Clinically Apparent Disease

American Journal of Medical Genetics Part A, EarlyView.
ABSTRACT Lymphatic disease represents a well‐described manifestation of Noonan syndrome (NS), yet the full phenotypic spectrum remains incompletely characterized, especially in asymptomatic individuals. We conducted a cross‐sectional study including 10 individuals with NS (four with peripheral lymphedema and six without) and 10 age‐ and sex‐matched ...

Refining a preclinical model of viral myocarditis in accordance with biotech standards

Animal Models and Experimental Medicine, EarlyView.
This study aimed to refine a murine model of Coxsackievirus B3‐induced myocarditis by integrating dietary and imaging innovations to improve animal welfare, data quality, and clinical applicability. The refined diet significantly reduced animal health burden, reduced weight loss, and stabilized blood glucose during development of cardiac inflammation ...

TWEAK/Fn14 Signaling Drives Oxidative Cardiac Injury in Systemic Lupus Erythematosus: Evidence From Patient Biomarker Studies, Lupus Mouse Models, and Cardiomyocyte Assays

Arthritis &Rheumatology, EarlyView.
Objective Cardiac involvement is a major cause of morbidity in systemic lupus erythematosus (SLE). Tumor necrosis factor–like weak inducer of apoptosis (TWEAK) is elevated in SLE, but its contribution to lupus‐associated cardiac injury is unclear. We investigated the role of TWEAK/fibroblast growth factor–inducible 14 (Fn14) signaling in SLE‐related ...

MT‐RNR1 genotype testing for preventing aminoglycoside‐mediated ototoxicity: A guideline developed by the UK Centre of Excellence in Regulatory Science and Innovation in Pharmacogenomics (CERSI‐PGx)

British Journal of Clinical Pharmacology, EarlyView.
Aminoglycosides are broad‐spectrum antibiotics used in the management of severe infections. Aminoglycosides are associated with nephrotoxicity and ototoxicity. Although dosing strategies such as once‐daily administration and therapeutic drug monitoring have reduced the incidence of nephrotoxicity, ototoxicity remains unpredictable and may occur at ...
