Cardiac magnetic resonance imaging (CMR) is an important clinical tool that obtains high-quality images for assessment of cardiac morphology, function, and tissue characteristics. However, the technique may be prone to artifacts that may limit the diagnostic interpretation of images. This article reviews common artifacts which may appear in CMR exams by describing their appearance, the challenges they mitigate true pathology, and offering possible solutions to reduce their impact. Additionally, this article acts as an update to previous CMR artifacts reports by including discussion about new CMR innovations.

Purpose: Homoarginine (hArg) is an arginine metabolite that has been known for years, but its physiological role in the body remains poorly understood. For instance, it is well known that high hArg concentrations in the blood are protective against several disease states, yet the mechanisms behind these health benefits are unclear. This review compiles what is known about hArg, namely its synthetic pathways, its role in different diseases and conditions, and its proposed mechanisms of action in humans and experimental animals.

This paper emphasizes the critical role of electrolyte selection in enhancing the electrochemical performance of nonaqueous Li-O batteries (LOBs). It provides a comprehensive overview of various electrolyte types and their effects on the electrochemical performance for LOBs, offering insights for future electrolyte screening and design. Despite recent advancements, current electrolyte systems exhibit inadequate stability, necessitating the urgent quest for an ideal nonaqueous electrolyte.

Adeno-associated virus (AAV) is a versatile viral vector technology that can be engineered for specific functionality in vaccine and gene therapy applications. One of the major challenges in AAV production is the need for a GMP-ready platform-based approach to downstream processing, as this would lead to a standardized method for multiple products. Chromatography has huge potential in AAV purification, as it is a scalable method that would enable manufacturing to a high degree of purity, potency, and consistency.
