Morphology of the patent arterial duct : features relevant to treatment [PDF]

, 2008
Patent ductus arteriosus (PDA), one of the most common congenital heart defects, is an abnormal persistence of a patent lumen in the arterial duct due to an arrest of the natural process of closure after it has served its function as a vital channel ...

Microvascular Damage Is Associated With Carotid Wall Structural Changes in Systemic Sclerosis: A Capillaroscopy and Ultrasound‐Based Observational Study

Arthritis Care &Research, EarlyView.
Objective Systemic sclerosis (SSc) is characterized by cardiovascular risk excess not fully explained by traditional factors. Whether the severity of microvascular damage correlates with structural subclinical atherosclerosis remains unclear. We investigated the relationship between nailfold videocapillaroscopy (NVC) abnormalities and carotid ...

Cross‐Scale Hierarchical Targeted Delivery System Based on Small‐Scale Magnetic Robots

Advanced Robotics Research, EarlyView.
This article reviews a cross‐scale hierarchical targeted delivery system that integrates magnetic continuum robots and magnetic microrobots. By combining rapid long‐range navigation with precise microscale targeting, the system overcomes key limitations of single‐scale approaches.

A randomized porcine study of hemorrhagic shock comparing end-tidal carbon dioxide targeted and proximal systolic blood pressure targeted partial resuscitative endovascular balloon occlusion of the aorta in the mitigation of metabolic injury

Intensive Care Medicine Experimental, 2023
Background The definition of partial resuscitative endovascular balloon occlusion of the aorta (pREBOA) is not yet determined and clinical markers of the degree of occlusion, metabolic effects and end-organ injury that are clinically monitored in real ...

Automating the determination of wave speed using the pu-loop method [PDF]

, 2005
The PU-loop (pressure-velocity loop) is a method for determining wave speed and relies on the linear relationship between the pressure and velocity in the absence of reflected waves.

Magnetic Micro‐ and Nanorobots for Precision Thrombolysis: Design Strategies and Translational Challenges

Advanced Robotics Research, EarlyView.
Micro‐ and nanorobots for targeted thrombolysis. This perspective elaborates on the clinical indication of blood clot disorders and current limitations for treatment. As a novel, alternative solution, micro‐ and nanorobots can be used to treat and break down thrombi.

Comparação e efeitos de dois diferentes tempos de oclusão da via aérea durante a mensuração da pressão inspiratória máxima em pacientes neurológicos na unidade de terapia intensiva de pacientes adultos Comparison and effects of two different airway occlusion times during measurement of maximal inspiratory pressure in adult intensive care unit neurological patients

Revista Brasileira de Terapia Intensiva, 2010
OBJETIVO: Verificar se os valores de pressão inspiratória máxima com o tempo de oclusão de 40 (PI 40) segundos são maiores do que no tempo de oclusão de 20s (PI 20) e as repercussões apresentadas pelo paciente por meio das variáveis fisiológicas ...

Intelligent Micro/Nanorobots for Targeted Interventional Therapy: From Bench to Clinic

Advanced Robotics Research, EarlyView.
Zirui Zhang et al. reviewed the application and challenges of mobile nanomachines in interventional therapy. By converting exogenous energy, including chemical, magnetic, optical, and ultrasonic sources, into mechanical forces, micro/nanorobots (MNRs) enable precise actuation at unprecedented scales. Evolving far beyond traditional drug delivery, these

Central command suppresses pressor‐evoked bradycardia at the onset of voluntary standing up in conscious cats

Experimental Physiology, 2023
It remains unclear whether cardiac baroreflex function is preserved or suppressed at the onset of standing up. To answer the question and, if cardiac baroreflex is suppressed, to investigate the mechanism responsible for the suppression, we compared the ...

Thermochemical Micro‐Explosion for Prompt Thrombolysis via Proximal Injection of Liquid Alkali Metal

Advanced Science, EarlyView.
We report a micro‐explosive thermochemical thrombolysis (METCT) therapy via injectable liquid alkali metal encapsulated in dimethyl silicone (LAM@oil). METCT enables prompt and safe vascular recanalization within 90 s. Critically, the LAM@oil system demonstrates significantly higher thrombolytic efficacy compared to clinically available thrombolytic ...
