Gene therapy targeting ischemic heart disease is a promising therapeutic avenue, but it is mostly restricted to viral-based delivery approaches which are limited due to off-target immunological responses. Focused ultrasound presents a non-viral, image-guided technique in which circulating intravascular microbubble contrast agents can reversibly enhance vascular permeability and gene penetration. Here, we explore the influence of flow rate on the microbubble-assisted delivery of miR-126, a potent pro-angiogenic biologic, using a custom acoustically coupled pressurized mesenteric artery model.

Arterial stiffness, as determined by pulse wave velocity (PWV), is a recognized marker of cardiovascular risk. Noninvasive technologies have enabled easier and more accessible assessments of PWV. The current gold standard for measuring carotid-femoral PWV (cfPWV)-a reliable indicator of arterial stiffness-utilizes applanation tonometry devices, as recommended by the Artery Society Guidelines.

Background: Inflammatory responses play a central role in myocardial ischemia/reperfusion (I/R) injury. Previous studies have demonstrated that the receptor for advanced glycation end-products (RAGE) is involved in the pro-inflammatory process of myocardial I/R injury by binding to diverse ligands. Thus, the inhibitory effects of soluble receptor for advanced glycation end-products (sRAGE), a decoy receptor for RAGE, on myocardial I/R injury may be associated with a reduced inflammatory state.

A 36-year-old male presented to the Emergency Department with clinical symptoms of blurred vision of progressive onset of two years of evolution. The ophthalmological examination revealed the existence of bilateral papilledema. Using cranial computed tomography and magnetic resonance imaging, the presence of a right occipital pial arteriovenous malformation was certified.

Infections with severe acute respiratory syndrome coronavirus 2 (SARS-CoV2) in pregnancy are associated with the development of preeclampsia and fetal growth restriction (FGR). Recently, preeclampsia was linked to impaired maternal hemodynamic function. This retrospective study evaluated singleton pregnancies with COVID-19 during pregnancy and healthy pregnant controls matched for gestational age from November 2020 to March 2022.
