Multiscale computational model predicts how environmental changes and treatments affect microvascular remodeling in fibrotic disease.

Investigating the molecular, cellular, and tissue-level changes caused by disease, and the effects of pharmacological treatments across these biological scales, necessitates the use of multiscale computational modeling in combination with experimentation. Many diseases dynamically alter the tissue microenvironment in ways that trigger microvascular network remodeling, which leads to the expansion or regression of microvessel networks. When microvessels undergo remodeling in idiopathic pulmonary fibrosis (IPF), functional gas exchange is impaired and lung function declines.

Diagnosing Allergic Contact Dermatitis Using Deep Learning: Single-Arm, Pragmatic Clinical Trial with an Observer Performance Study to Compare Artificial Intelligence Performance with Human Reader Performance.

Allergic contact dermatitis is a common, pruritic, debilitating skin disease, affecting at least 20% of the population. To prospectively validate a computer vision algorithm across all Fitzpatrick skin types. Each participant was exposed to 10 allergens.

Decellularized porcine dermal hydrogel enhances implant-based wound healing in the setting of irradiation.

Acellular Dermal Matrix (ADM) provides mechanical and soft tissue support in implant-based breast reconstruction, and has shown to modulate the healing response. However, skin flap necrosis, edema, and previous radiation therapy can hinder ADM integration. Effective biomaterial integration requires regulating the immune response, fibrosis, and adipocyte-driven functionalization.

Pediatric Neural Changes to Physical and Emotional Pain After Intensive Interdisciplinary Pain Treatment: A Pilot Study.

Objective: Brain areas activated during pain can contribute to enhancing or reducing the pain experience, showing a potential connection between chronic pain and the neural response to pain in adolescents and youth.

Methods: This study examined changes in brain activation associated with experiencing physical pain and observing physical and emotional pain in others by using functional magnetic resonance imaging (fMRI) before and after intensive interdisciplinary pain treatment (IIPT). Eighteen youths (age 14 to 18) with widespread chronic pain completed fMRI testing before and after IIPT to assess changes in brain activation in response to physical and emotional pain.

Connecting transcriptomics with computational modeling to reveal developmental adaptations in pediatric human atrial tissue.

Nearly 1% of babies are born with congenital heart disease-many of whom will require heart surgery within the first few years of life. A detailed understanding of cardiac maturation can help to expand our knowledge on cardiac diseases that develop during gestation, identify age-appropriate drug therapies, and inform clinical care decisions related to surgical repair and postoperative management. Yet, to date, our knowledge of the temporal changes that cardiomyocytes undergo during postnatal development is limited.
