Dimethyl Fumarate Mediates Sustained Vascular Smooth Muscle Cell Remodeling in a Mouse Model of Cerebral Aneurysm.

Cerebral aneurysms (CA) are a type of vascular disease that causes significant morbidity and mortality with rupture. Dysfunction of the vascular smooth muscle cells (VSMCs) from circle of Willis (CoW) vessels mediates CA formation, as they are the major cell type of the arterial wall and play a role in maintaining vessel integrity. Dimethyl fumarate (DMF), a first-line oral treatment for relapsing-remitting multiple sclerosis, has been shown to inhibit VSMC proliferation and reduce CA formation in a mouse model.

Single-Cell Transcriptome Analysis of the Circle of Willis in a Mouse Cerebral Aneurysm Model.

Background: The circle of Willis (CoW) is the most common location for aneurysms to form in humans. Although the major cell types of the intracranial vasculature are well known, the heterogeneity and relative contributions of the different cells in healthy and aneurysmal vessels have not been well characterized. Here, we present the first comprehensive analysis of the lineage heterogeneity and altered transcriptomic profiles of vascular cells from healthy and aneurysmal mouse CoW using single-cell RNA sequencing.

Torcular Herophili: A Review of the History of the Term and Synonyms.

The eponymous term torcular Herophili has been used for the confluence of sinuses. Although no original writings of Herophilus are extant, his accomplishments and descriptions live on in the writings of such authors as Galen. However, in regard to the torcular Herophili, there are some inconsistencies in the secondary sources and their translations regarding what was actually originally described by Herophilus.

Anatomy of the Dorsal Meningeal Artery Including Its Variations: Application to Skull Base Surgery and Diagnostic and Interventional Imaging.

Background: The blood supply to the skull base is important to surgeons and those performing interventional and diagnostic procedures in this region. However, 1 vessel with a vast distribution in this area, the dorsal meningeal artery (DMA), has had few anatomic studies performed to investigate not only its normal anatomy but also its variations. Therefore the current study aimed to analyze the DMA via cadaveric dissection.

Multisite Culinary Medicine Curriculum Is Associated With Cardioprotective Dietary Patterns and Lifestyle Medicine Competencies Among Medical Trainees.

Adherence to Mediterranean dietary patterns reduces the incidence of cardiovascular disease and other major chronic diseases. We aimed to assess the association between participation in kitchen-based nutrition education and Mediterranean diet intake and lifestyle medicine counseling competencies among medical trainees. The Cooking for Health Optimization with Patients (CHOP) curriculum is a hands-on cooking-based nutrition education program implemented at 32 medical programs (4125 medical trainees) across the United States.
