25-Year Comparison of Coronary Lesions Anatomy in Two Cohorts of French Canadians with Familial Hypercholesterolemia.

Over the past decades, new treatments and guidelines have been introduced for the screening and management of familial hypercholesterolemia (FH). However, the impact of these medical and scientific advances on the characteristics and burden of coronary lesions over time in FH remains poorly documented. The primary goal of this study is to determine the characteristics of coronary lesions in HeFH patients who underwent coronary angiography within two distinct timeframes: the last five years versus those who had the procedure at the same hospital 25 years earlier.

Cardiopulmonary Impact of the Minimally Invasive Repair of Pectus Excavatum in Pediatric patients: A Prospective Pilot Study.

Introduction: The physiologic benefits of the minimally invasive repair of pectus excavatum (MIRPE) on cardiopulmonary function are poorly understood in pediatrics. We sought to examine the effects of MIRPE on exercise response during cardiopulmonary exercise testing (CPET).

Methods: A prospective-pilot study was conduct of patients ≤18 years who presented for pectus bar removal.

An Activity-Based Sensing Approach to Multiplex Mapping of Labile Copper Pools by Stimulated Raman Scattering.

Molecular imaging with analyte-responsive probes offers a powerful chemical approach to studying biological processes. Many reagents for bioimaging employ a fluorescence readout, but the relatively broad emission bands of this modality and the need to alter the chemical structure of the fluorophore for different signal colors can potentially limit multiplex imaging. Here, we report a generalizable approach to multiplex analyte imaging by leveraging the comparably narrow spectral signatures of stimulated Raman scattering (SRS) in activity-based sensing (ABS) mode.
