Current challenges in the diagnosis and treatment of cardiac myxoma [PDF]

, 2020
Cardiac myxoma is the most common benign cardiac tumor. It is located in the left atrium and typically arises from the foramen ovale in approximately 75% of the general patient population, in the right atrium in 23%, and in the ventricles in only 2 ...

Conjugated Porphyrin Polymer With Superior Charge Transfer for Photodynamic‐Immunomodulatory Prevention of CIED Infection in Diabetes

Advanced Healthcare Materials, EarlyView.
Under NIR irradiation, PTCPP generates ROS to eliminate MRSA biofilms and promote M1 macrophage polarization for phagocytosis. After bacterial clearance, the material is phagocytosed by macrophages, shifting their polarization to M2 phenotype via metabolic reprogramming, which synergistically enhances anti‐infection therapy and wound healing.

A Common Disease, an Uncommon Location: Left Ventricle Papillary Fibroelastoma

Oman Medical Journal
Cardiac papillary fibroelastoma (PFE) is a rare benign cardiac tumor, usually associated with cardiac valves. Cases of non-valvular, left ventricular (LV) cavity PFE are extremely rare. We report the case of a 75-year-old man with a history of exertional

Engineered Nanoplatforms Targeting Activated Hepatic Stellate Cells for Liver Fibrosis Therapy via TGF‐β Axis Inhibition and Ferroptosis Induction

Advanced Healthcare Materials, EarlyView.
FeS‐VA@lanifibranor (FVL), an activated hepatic stellate cell (aHSC)‐targeted nanoplatform comprising vitamin A‐functionalized two‐dimensional iron sulfide nanosheets and lanifibranor, is engineered for precision therapy of liver fibrosis. FVL suppresses the TGF‐β signaling pathway by inhibiting SMAD2/3 phosphorylation and induces ferroptosis in aHSCs,

The Indian Academy of Echocardiography practice guideline for the performance of transesophageal echocardiographic evaluation of a patient with cerebrovascular stroke

Journal of the Indian Academy of Echocardiography & Cardiovascular Imaging, 2018
Ischemic stroke remains a major cause of morbidity and mortality. Cardiac sources of embolism account for almost up to 40% of all the ischemic strokes. Accordingly, echocardiography is an important investigation in the evaluation of clinically suspected ...

Near‐Infrared Light‐Activated Polydopamine Nanoparticles Conjugated With Transferrin Peptides for Enhanced Brain Accumulation

Advanced Healthcare Materials, EarlyView.
This study demonstrates that Tf‐PDA NPs combine a receptor‐mediated targeting with mild photothermal activation to enhance nanoparticle accumulation in the brain. NIR‐activated Tf‐PDA NPs increase BBB permeability to NPs in vitro and in vivo without inducing cytotoxicity or adverse immune responses.
