Embolic myocardial infarction associated with patent foramen ovale: a case series

Кардиоваскулярная терапия и профилактика, 2023
A patent foramen ovale (PFO) is a fairly common mild cardiac defect that causes a shunting across the atrial septum. PFO is also a known risk factor for cryptogenic stroke. Much less frequently, PFO is associated with non-cerebral systemic embolic events.

Tumor‐Specific Delivery of CD28 siRNA via Lyso‐PC C‐16 Modified Lipid Nanoparticles Overcomes Anti‐PD‐1 Resistance by Remodeling Tumor Microenvironment

Advanced Science, EarlyView.
This study develops 16:0 LPC‐modified lipid nanoparticles (LPC‐LNPs) with cancer cell specificity by exploiting altered tumor lipid metabolism. LPC‐LNPs encapsulating Cd28 small interfering RNA (LPC‐LNP‐Cd28) knock down cancer cell CD28 without affecting T cells, inflame the tumor microenvironment, and overcome anti‐PD‐1 resistance.

Spatiotemporal Targeting Randle Cycle and Immune Checkpoint for Potent Antitumor Therapy

Advanced Science, EarlyView.
A glucose oxidase‐based nanogel (GOX‐NG) system using catechol‐functionalized alginate, exhibits enhanced tumor penetration, prolonged retention, and sustained glucose depletion in the tumor microenvironment. When combined with a fatty acid oxidation inhibitor, it implements dual metabolic suppression, thereby enhancing ROS‐induced immunogenic cell ...

Successful surgical treatment of impending paradoxical embolism with pulmonary embolism and myocardial infarction

Journal of Cardiothoracic Surgery
Background Paradoxical embolism is a rare cause of acute arterial occlusion. This phenomenon arises when embolic material travels from the venous system crosses an abnormal shunt such as patent foramen ovale, atrial septal defects, ventricular septal ...

Paradoxical embolism in Ebstein's anomaly [PDF]

, 2001
A 26-year-old man with Ebstein's anomaly had cerebellar infarction due to paradoxical embolism. Ebstein's anomaly is characterized by a downward displacement of the tricuspid valve into the right ventricle due to anomalous attachment of the tricuspid ...

Overcoming Interfacial Hurdles in Solid‐State Aluminum Batteries for Safe and Energy‐Dense Storage

Advanced Science, EarlyView.
Solid‐state aluminum batteries (SSABs) promise high energy density and intrinsic safety but face severe solid–solid interfacial challenges. This review reveals the three core hurdles—anode passivation, cathode contact loss, and electrolyte grain boundary resistance and discusses strategies including artificial interphases, alloying, and composite ...

Paradoxical Embolism and a Patent Foramen Ovale. [PDF]

, 1998
Patients who sustain an unexplained stroke or peripheral ischemic event should be examined for paradoxical embolism via right-to-left shunting. The confirmation of a patent foramen ovale by echocardiography is simple and noninvasive, and should suggest ...

Giant Exfoliation Induced Magnetic Coercivity in Fe3GaTe2

Advanced Electronic Materials, EarlyView.
Mechanical exfoliation is shown to transform the van der Waals ferromagnet Fe3GaTe2 from a soft into a hard magnetic system. Reducing thickness drives a crossover to single‐domain behavior, dramatically enhancing in‐plane coercivity to near–permanent‐magnet levels at room temperature.

Patent Foramen Ovale: Is Stroke Due to Paradoxical Embolism? [PDF]

, 1993
Background and Purpose: A patent foramen ovale has been reported to be significantly more frequent in young stroke patients than in matched control subjects, and paradoxical embolism has been suggested as the main mechanism of stroke in-this situation ...
