A Case of Limb Ischemia Secondary to Paradoxical Embolism

, 2010
Paradoxical embolism is rarely considered a cause for acute limb ischemia. Although patent foramen ovales (PFOs) are often seen in young patients with stroke, clinicians may not consider evaluation for PFOs in young patients with acute peripheral ...

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.

Paradoxical pulmonary embolism with spontaneous aortocaval fistula

, 2012
Paradoxical pulmonary embolisms are uncommon emergencies and can occur as a consequence of an aortocaval fistula due to unrecognized dislodgement of thrombus from aortic sac into pulmonary circulation.

Almost a Double Whammy! Acute Pulmonary Embolism and an Impending Paradoxical Embolism

Journal of the Indian Academy of Echocardiography & Cardiovascular Imaging
Pulmonary embolism (PE) is a relatively common cardiovascular disorder with high early mortality rates, despite advances in diagnosis and treatment. The risk of mortality is quite high in case the diagnosis is missed.

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 ...

High-Risk Pulmonary Embolism with Impending Paradoxical Embolism Successfully Treated with Percutaneous Catheter-Based Thrombectomy

, 2011
Impending paradoxical embolism is a rare condition defined as the presence of an entrapped thrombus through the patent foramen ovale. This diagnosis is usually made from echocardiography or a thoracic-CT scan performed in patients with suspected ...
