Sonosensitive dioleoylphosphatidylethanolamine-containing liposomes with prolonged blood circulation time of doxorubicin [PDF]
European Journal of Pharmaceutical Sciences, 2011 Ultrasound sensitive (sonosensitive) liposomes represent a drug delivery system designed for releasing a drug load upon exposure to ultrasound (US). Inclusion of dioleoylphosphatidylethanolamine (DOPE) in liposome membranes was previously shown to induce sonosensitivity.

15O-water PET for evaluation of cardiopulmonary perfusion in complex cyanotic heart disease
European Journal of Hybrid Imaging, 2020 Background Dynamic 15O-water PET may provide information about cardiopulmonary circulation complementary to MRI and CT in complex cyanotic heart disease. Case presentation We present a case in which a 15O-water PET scan was used for the first time to map

Brain stem death as the vital determinant for resumption of spontaneous circulation after cardiac arrest in rats. [PDF]
PLoS ONE, 2009 BACKGROUND:Spontaneous circulation returns to less than half of adult cardiac arrest victims who received in-hospital resuscitation. One clue for this disheartening outcome arises from the prognosis that asystole invariably takes place, after a time lag,

Real-Time Blood Circulation and Bleeding Model for Surgical Training
IEEE Transactions on Biomedical Engineering, 2013 Intraoperative management of bleeding is a critical skill all surgeons must possess. It is, however, very challenging to create a safe and realistic learning environment for its acquisition. In this paper, we propose a simple and efficient approach to integrate blood circulation to computerized surgical simulation systems and allow for real-time ...

Impaired coronary blood flow at higher heart rates during atrial fibrillation: investigation via multiscale modelling [PDF]
, 2019 Background. Different mechanisms have been proposed to relate atrial fibrillation (AF) and coronary flow impairment, even in absence of relevant coronary artery disease (CAD). However, the underlying hemodynamics remains unclear.

Control Strategy Design of a Microblood Pump Based on Heart-Rate Feedback
Micromachines, 2022 Based on the nonlinear relationship between heart rate and stroke volume, a flow model of left ventricular circulation was improved, and a variable-speed blood-pump control strategy based on heart-rate feedback was proposed.

Erythrocytes Nanoparticle Delivery: A Boon for Targeting Tumor [PDF]
Advanced Pharmaceutical BulletinAlthough nanoparticles (NPs) have many advantages as drug delivery systems, their poor stability in circulation, premature drug release, and nonspecific uptake in non-target organs have prompted biomimetic approaches to camouflage nano vehicles using ...
