Intrauterine growth restriction (IUGR) is the second most common obstetric complication after preterm labor. Appropriate trophoblast differentiation and placental structure, growth and function are key for the maintenance of pregnancy and normal fetal growth, development and survival. Extravillous trophoblast cell proliferation, migration and invasion are regulated by molecules produced by the fetomaternal interface, including autocrine factors produced by the trophoblast, such as insulin‑like growth factor (IGF)‑1.

Nile blue has been widely used in histological staining, fluorescence labeling, and DNA probing, with its intercalation behavior into the DNA helix being well documented. Here, we present a comprehensive investigation to address a current knowledge gap regarding the binding properties of Nile blue to two types of double-stranded RNA (dsRNA): poly(A·U) and poly(I·C), using various biophysical techniques. Absorption and fluorescence spectroscopic studies suggest a significant binding interaction between Nile blue and the two designated dsRNAs, specifically indicating an intercalation binding mode with poly(A·U) and demonstrating a noticeably higher binding affinity compared to poly(I·C).

Division of Cardiac Surgery, Department of Surgery, University of Chicago, Chicago, Illinois.
Background: Patient-specific, 3-dimensional printed, tissue engineered vascular grafts (3DTEVGs) are manufactured to optimize hemodynamic performance and to accommodate growth. We evaluate growth outcomes of 3DTEVGs compared with standard grafts for pulmonary artery reconstruction in porcine models.
Methods: Magnetic resonance imaging (MRI) with 4-dimensional flow data was acquired in porcine models (n = 8).
Maternal nutrition and offspring lung health: sex-specific pathway modulation in fibrosis, metabolism, and immunity.

Background: Maternal nutrition profoundly influences offspring health, impacting both prenatal and early postnatal development. Previous studies have demonstrated that maternal dietary habits can affect key developmental pathways in the offsprings, including those related to lung function and disease susceptibility. However, the sex-specific impact of a maternal high-salt diet (HSD) on offspring lung injury remains poorly understood.

Enthesitis, or inflammation specific to sites in the body where tendon inserts into bone, can arise in isolated joints from overuse or in multiple joints as a complication of an autoimmune condition such as psoriatic arthritis or spondyloarthritis. However, the pathogenesis of enthesitis is not well understood, so treatment strategies are limited. A clinically relevant animal model of enthesitis would allow investigators to determine mechanisms driving the disease and evaluate novel therapies.
