An optimized plasmalogen modulating dietary supplement provides greater protection in a male than female mouse model of dilated cardiomyopathy.

We previously reported that plasmalogens, a class of phospholipids, were decreased in a setting of dilated cardiomyopathy (DCM). Plasmalogen levels can be modulated via a dietary supplement called alkylglycerols (AG) which has demonstrated benefits in some disease settings. However, its therapeutic potential in DCM remained unknown.

The Proteomic Landscape of the Coronary Accessible Heart Cell Surfaceome.

Cell surface proteins (surfaceome) represent key signalling and interaction molecules for therapeutic targeting, biomarker profiling and cellular phenotyping in physiological and pathological states. Here, we employed coronary artery perfusion with membrane-impermeant biotin to label and capture the surface-accessible proteome in the neo-native (intact) heart. Using quantitative proteomics, we identified 701 heart cell surfaceome accessible by the coronary artery, including receptors, cell surface enzymes, adhesion and junctional molecules.

A Prospective Randomized Multicenter Study on the Impact of [F]F-Choline PET/CT Versus Conventional Imaging for Staging Intermediate- to High-Risk Prostate Cancer.

This study aimed to compare the efficacy of [F]F-choline PET/CT with conventional imaging for staging and managing intermediate- to high-risk prostate cancer (PCa). The primary objective was to assess the ability of PET/CT with [F]F-choline to identify lymph node and systemic involvement during initial staging. Secondary objectives included evaluating the impact of [F]F-choline PET/CT on unnecessary local treatments and assessing the safety of [F]F-choline agents.
