This paper focuses on the modelling of fluid-structure interaction and wave propagation problems in a stented artery. Reflection of waves in blood vessels is well documented in the literature, but it has always been linked to a strong variation in geometry, such as the branching of vessels. The aim of this work is to detect the possibility of wave reflection in a stented artery due to the repetitive pattern of the stents. The investigation of wave propagation and possible blockages under time-harmonic conditions is complemented with numerical simulations in the transient regime.

Background: Studies suggest a potential link between stroke and Alzheimer's disease wherein stroke may serve as a trigger for the onset or acceleration of Alzheimer's pathogenesis as damage to the brain's blood vessels may lead to the accumulation of amyloid beta protein which is a hallmark of Alzheimer's disease. Recent research has shown that stroke treatment may hold the key to treating Alzheimer's disease. The anti-inflammatory potentials of Cholinergic signaling are a novel therapeutic target in memory decline associated with Alzheimer's.

Background: Luminal and hemodynamic evaluations of the cervical arteries inform the diagnosis and management of patients with cervical arterial disease.
Purpose: To demonstrate a 3D nonenhanced quantitative quiescent interval slice-selective (qQISS) magnetic resonance angiographic (MRA) strategy that provides simultaneous hemodynamic and luminal evaluation of the cervical arteries.

Background: Microvascular dysfunction (MVD) is a recognized sign of disease in heart failure progression. Intact blood vessels exhibit abnormal vasoreactivity in early stage, subsequently deteriorating to rarefaction and reduced perfusion. In managing heart failure with preserved ejection fraction (HFpEF), earlier diagnosis is key to improving management.

Non-functioning pituitary adenomas (NFPAs) are hormonally inactive benign tumors, usually diagnosed as macro-adenoma. The aim of our research was to analyze the clinical and hormonal characteristics of NFPAs using Knosp and revised Knosp classifications. Furthermore, we aimed to assess the possibility of predicting surgical remission after surgery.

Intracardiac migration of inferior vena cava (IVC) filter or stent is a rare but potentially fatal complication of endovascular venous device placement. There is no consensus whether migrated stents should be surgically removed by open cardiac surgery or retrieved by the percutaneous endovascular route and whether an intervention should be performed immediately or expectantly. Herein, we report a 39-year-old female who received emergent left lobe living donor liver transplantation (LDLT) owing to posthepatectomy liver failure.
