Endothelial cell (EC)-specific CTGF/CCN2 Expression Increases EC Reprogramming and Atherosclerosis.

Department of Surgery, Emory University, Atlanta, GA, USA; Wallace H. Coulter Department of Biomedical Engineering, Georgia Institute of Technology and Emory University, Atlanta, GA, USA; Research Services, Atlanta VA Medical Center, Decatur, GA, USA. Electronic address:
Arterial endothelial cells (ECs) reside in a complex biomechanical environment. ECs sense and respond to wall shear stress. Low and oscillatory wall shear stress is characteristic of disturbed flow and commonly found at arterial bifurcations and around atherosclerotic plaques.

Background: Electrographic flow (EGF) mapping allows for the visualization of global atrial wavefront propagations. One mechanism of initiation and maintenance of atrial fibrillation (AF) is stimulation from EGF-identified focal sources that serve as driver sites of fibrillatory conduction. Electrographic flow consistency (EGFC) further quantifies the concordance of observed wavefront patterns, indicating that a healthier substrate shows more organized wavefront propagation and higher EGFC.

January 2025
Department of Neurosurgery, Center of Pituitary Tumor, Ruijin Hospital Shanghai Jiao Tong University School of Medicine Shanghai China.
Background: Carotid endarterectomy (CEA) is widely used to treat carotid artery stenosis (CAS). However, the effects of CEA on unilateral CAS-induced cognitive impairment and the underlying mechanism remain poorly understood.
Methods And Results: Thirteen patients diagnosed with unilateral severe CAS underwent pre- and post-CEA assessments, including fluoro-2-deoxy-d-glucose positron emission tomography/magnetic resonance imaging, cognitive assessments, and routine blood tests before and after CEA.
Correlating autonomic physiology with symptoms of autonomic dysreflexia after spinal cord injury.

January 2025
Department of Physical Medicine and Rehabilitation, Mayo Clinic, Rochester, Minnesota, USA.
Background: Individuals with spinal cord injury (SCI) commonly have autonomic dysreflexia (AD) with increased sympathetic activity. After SCI, individuals have decreased baroreflex sensitivity and increased vascular responsiveness.
Objective: To evaluate the relationship between baroreflex and blood vessel sensitivity with AD symptoms.
An atrial septal defect (ASD) is a common congenital heart anomaly that results in irregular blood flow between the systemic and pulmonary circulations due to an opening in the atrial septum. Ostium secondum ASD accounts for a large proportion of these defects and often goes unnoticed during childhood and adolescence. Pulmonary hypertension (PH), affecting a significant number of patients with ostium secondum ASD, is associated with functional limitations, heart failure, and tachyarrhythmias.
