Cardiovascular System Sonographic Evaluation Algorithm

open access: yes, 2015
Objectives: To evaluate the reproducibility and feasibility of the new cardiovascular system sonographic evaluation algorithm for studying the extended fetal cardiovascular system, including the portal, thymic, and supra-aortic areas, in the second ...

Degradation mechanism of the von Willebrand factor A2 domain by nattokinase

open access: yesFEBS Letters, EarlyView.
Nattokinase, a natto‐derived protease, exhibits potent antithrombotic effects. This study demonstrates that nattokinase directly cleaves the von Willebrand factor (vWF) A2 domain in vitro. Unlike the native regulator ADAMTS13, nattokinase degrades folded vWF independently of shear stress.

Microbiome‐blood–brain barrier interactions in aging — mechanisms and therapeutic potential

open access: yesFEBS Letters, EarlyView.
Aging reshapes the gut microbiome (↓SCFA‐producing commensals; ↑pro‐inflammatory outputs), shifting circulating metabolites (↓SCFAs; ↑LPS, ↑TMAO, ↑PAA) that act at the BBB to increase nonspecific transcytosis, alter transport, and promote astrocyte reactivity, heightening brain vulnerability.

Timely Management of Obstructive Prosthetic Valve Thrombosis

open access: yesJACC: Case Reports, 2019
Obstructive bioprosthetic valve thrombosis is associated with hemodynamic compromise, and evidence on management with fibrinolysis is limited. Echocardiography is required to assess thrombus size and its effects on valve gradients, area, and leaflet ...

Acute Myocardial Infarction With Cardiogenic Shock Due to Pericardial Constriction and Multivessel Coronary Obstruction

open access: yesJACC: Case Reports, 2020
We present a rare case of cardiogenic shock and multivessel coronary compression due to focal pericardial inflammation and constriction. The patient was treated in the acute phase with coronary stenting and temporary mechanical support.

Physician-modified aortic cuff to “stabilize” paravisceral aortic thrombus and minimize risk of distal embolization during pararenal aneurysm repair with fenestrated stent graft

open access: yesJournal of Vascular Surgery Cases and Innovative Techniques, 2022
As technology and surgeon experience evolve, endovascular repair of complex abdominal aortic aneurysms is often preferred in appropriately selected patients. However, the presence of pedunculated aortic thrombus represents a relative contraindication for

Leptin and the Cardiovascular System

open access: yesRecent Progress in Hormone Research, 2004
Obesity is associated with increased cardiovascular morbidity and mortality, in part through development of hypertension. Recent observations suggest that the cardiovascular actions of leptin may help explain the link between excess fat mass and cardiovascular diseases.

Partial depletion of plasminogen activator inhibitor‐1 decreases subcutaneous fat cell hypertrophy and liver cholesterol in high‐fat‐fed female mice

open access: yesFEBS Letters, EarlyView.
Obesity raises blood levels of PAI‐1, a protein linked to metabolic dysfunction‐associated steatotic liver disease in people with obesity. In female mice fed a high‐fat diet, partially lowering PAI‐1 led to smaller subcutaneous fat cells and lower liver cholesterol, without changing body weight or insulin sensitivity.

Hemostatic efficacy of a flowable collagen-thrombin matrix during coronary artery bypass grafting: a double-blind randomized controlled trial

open access: yesJournal of Cardiothoracic Surgery, 2023
Background Flowable hemostatic agents have the advantage of being able to be applied to irregular wound surfaces and difficult to reach areas. We sought to compare the effectiveness and safety of the flowable hemostatic sealants Collastat® (collagen ...
