Bounded projections to the Z$\mathcal {Z}$‐factor graph

Journal of Topology, Volume 18, Issue 2, June 2025.
Abstract Suppose that G$G$ is a free product G=A1∗A2∗⋯∗Ak∗FN$G = A_1 * A_2* \cdots * A_k * F_N$, where each of the groups Ai$A_i$ is torsion‐free and FN$F_N$ is a free group of rank N$N$. Let O$\mathcal {O}$ be the deformation space associated to this free product decomposition. We show that the diameter of the projection of the subset of O$\mathcal {O}

Effects of cardiac motion on dose distribution during stereotactic arrhythmia radioablation treatment: A simulation and phantom study

Journal of Applied Clinical Medical Physics, Volume 26, Issue 5, May 2025.
Abstract Purpose Cardiac motion may degrade dose distribution during stereotactic arrhythmia radioablation using the CyberKnife system, a robotic radiosurgery system. This study evaluated the dose distribution changes using a self‐made cardiac dynamic platform that mimics cardiac motion. Methods The cardiac dynamic platform was operated with amplitudes

P21‐Activated Kinase 2 as a Novel Target for Ventricular Tachyarrhythmias Associated with Cardiac Adrenergic Stress and Hypertrophy

Advanced Science, Volume 12, Issue 17, May 8, 2025.
Ca2+/calmodulin‐dependent kinase II (CaMKII) activation is likely driven by oxidative stress, particularly excessive reactive oxygen species (ROS) production. This study identifies P21‐activated kinase 2 (Pak2) as a novel regulator of ROS‐induced CaMKII activation and abnormal Ca2⁺ dynamics in acute adrenergic and chronic pressure‐overload stressed ...

Successful Aspiration Thrombectomy for Cocaine‐Induced Right Coronary Artery Embolism Secondary to Left Ventricular Thrombus: A Case Report and Literature Review

Clinical Case Reports, Volume 13, Issue 5, May 2025.
ABSTRACT Coronary embolism (CE) is a rare yet significant contributor to acute myocardial infarction (AMI), particularly in younger patients. We report a 42‐year‐old male who experienced an AMI following recent cocaine use. Investigations revealed a left ventricular apical thrombus, identified as the source of a distal embolus occluding the right ...

Right Heart Obstructive Disease due to Tumoral Infiltration

Clinical Case Reports, Volume 13, Issue 5, May 2025.
ABSTRACT Cardiac tumor infiltration can present with right heart obstruction and peripheral congestion, mimicking other causes of heart failure. Early recognition through imaging is crucial, as surgical intervention may be lifesaving in select cases.

A Comprehensive Review of Two‐Dimensional Speckle‐Tracking Echocardiography in Assessing Right and Left Ventricular Function in Diabetic Patients

Clinical Cardiology, Volume 48, Issue 5, May 2025.
This figure illustrates the application of 2D speckle‐tracking echocardiography (2D‐STE) in assessing cardiac function in diabetes patients. At the center, a detailed anatomical representation of the heart is shown, highlighting the areas that can be evaluated using this advanced imaging technique.

Modeling Hemodynamic Effects of the Closure Procedure of Carotid Artery Endarterectomy

International Journal for Numerical Methods in Biomedical Engineering, Volume 41, Issue 5, May 2025.
In this study, computational fluid dynamics and geometrical analysis are applied to two patients postcarotid artery endarterectomy (CEA), each closed with a different method. The patch patient who restenosed exhibited a nonphysiological hemodynamic environment, in contrast to the successful primary closure patient.

Adrenal Insufficiency Associated Cardiomyopathy, From Molecule to Clinic: A Comprehensive Review

Health Science Reports, Volume 8, Issue 5, May 2025.
ABSTRACT Background and Aim Adrenal insufficiency (AI), the lack of glucocorticoids (GCs) production or function with or without a lack of mineralocorticoids (MCs) and adrenal androgens, can result in uncommon but life‐threatening complications like shock, circulatory failure, syncope, arrhythmias, dilated cardiomyopathy (DCM), and congestive heart ...

Application Value of Myocardial Segmental Thickness Variability Measured by Echocardiography in Distinguishing Ischemic and Nonischemic Dilated Cardiomyopathy

Journal of Clinical Ultrasound, Volume 53, Issue 4, Page 664-669, May 2025.
Echocardiographic measurement of myocardial segmental thickness variability (STV) effectively differentiates between ischemic and nonischemic dilated cardiomyopathy. STV, combined with regional wall motion abnormalities (RWMA), provides high diagnostic accuracy, offering a noninvasive alternative to coronary angiography for guiding treatment strategies.
