Background: Device-based embolization is a well-established medical procedure for treating several pathological conditions, including cerebral and peripheral pseudoaneurysms, congenital defects, and active bleeding. Nonetheless, an intriguing and relatively underexplored application of coils and microparticles involves the preoperative reduction of blood supply to ectopic masses.
Case Summary: A 58-year-old woman was admitted to our institution with nausea and confusion, with a suspected diagnosis of syndrome of inappropriate antidiuretic hormone secretion. A computed tomography scan revealed a large mediastinal mass receiving blood supply from both the bronchial and coronary arteries. The mass was successfully excised surgically, following the embolization of the major feeding vessels using a combination of coils and microspheres.
Discussion: An uncommon presentation of a paraganglioma characterized by both mass effect and endocrine activity required a "neoadjuvant" treatment to ensure safer surgical management.
Take-home Message: The percutaneous reduction of blood supply to tumoral mass could represent an effective strategy to guarantee a radical excision without major complications.

Purpose: This study aimed to investigate the effects of extraocular muscle recession performed as part of strabismus surgery on posterior retinal and choroidal blood flow.
Methods: A single-center prospective study was conducted on patients who underwent strabismus surgery. Optical coherence tomography, optical coherence tomography angiography, and laser speckle flowgraphy of the macula were performed before surgery and at one week, one month, and four months after surgery.

The engraftment of transplanted islets depends on the rapid establishment of a novel vascular network. The present study evaluated the effects of cord blood-derived blood outgrowth endothelial cells (BOECs) on the viability of neonatal porcine islets (NPIs) and the post-transplant outcome of grafted NPIs. Dispersed NPIs and human BOECs were reaggregated on microwell cell culture plates and tested for their anti-apoptotic and pro-angiogenic capacity by qRT-PCR and immunohistochemistry.

The anatomic and radiographic characteristics of the pediatric proximal femur, including the presence of an active growth plate, an immature femoral calcar, greater trabecular density and plasticity and a relatively immature blood supply are very different from those of the adult proximal femur. Treatment protocols for PFNFs must differ from those for adult femoral neck fractures.

Immunosenescence, age-related immune dysregulation, reduces immunity upon vaccinations and infections. Cytomegalovirus (CMV) infection results in declining naïve (T) and increasing terminally differentiated (T) T cell populations, further aggravating immune aging. Both immunosenescence and CMV have been speculated to hamper the formation of protective T-cell immunity against novel or emerging pathogens.

Introduction: Acute coronary syndrome refers to a group of diseases characterized by sudden, decreased blood supply to the heart muscle that results in cell death, also known as acute myocardial infarction. This results in severe chest pain or discomfort, with the subsequent release of cardiac biomarkers, and alterations in the electrocardiogram. It can cause diminished heart function and mortality if not treated properly with suitable measures.
