After a yearlong hiatus, Behind the Bench is back, listeners! In this episode, we welcome back our B2B co-hosts Dr. Charlotte Usselman and Dr. Tommy Martin, who get the story behind the story from the one and only Dr. DeWayne Townsend, corresponding author of the recently published study by Stevens et al. Trust me, you are going to love listening to DeWayne talk about science! As DeWayne rightly points out, if we want to understand a disease before it's a disease, we have to model it in order to figure it out. From the “dastardly Krebs cycle” to grinding up hearts and shouting “fire in the hol ..read more

In our latest episode, Associate Editor Dr. Amanda LeBlanc (University of Louisville) interviews author Prof. Pietro Modesti (University of Florence) and expert Dr. Alexandre da Silva (University of Mississippi Medical Center) about the new study by Pellegrino et al. that investigated the pattern of intraventricular hemodynamic forces associated with left ventricular function in women with uncomplicated twin pregnancy. The authors found that, in twin pregnancy, hemodynamic forces misalignment in the first trimester precedes a slight temporary decrease in left ventricular systolic function in t ..read more

Ready Player One? In our latest episode, Dr. Keith Brunt (Dalhousie University) interviews lead author Dr. Joanne DiFrancisco-Donoghue (New York Institute of Technology) and expert Dr. Saurabh Thosar (Oregon Health and Science University Hospital) about a new article published in the AJP-Heart and Circ Call for Papers on Exercise, Physical Activity, and Cardiovascular Health.

In our latest episode, Associate Editor Dr. Crystal Ripplinger (University of California, Davis) interviews author Dr. Tim Domeier (University of Missouri) and expert Dr. DeWayne Townsend (University of Minnesota) about the recent study by Haffner et al et al. The authors examined cardiac calcium mishandling and damage in the setting of Duchenne muscular dystrophy (DMD). Using a genetic mouse model of DMD crossed with a mouse that expresses a genetically encoded calcium indicator, Domeier and c ..read more

People living with HIV have an increased risk of developing cardiovascular disease, including coronary artery disease. Until now, it has been unclear why. In this episode, Guest Editor Dr. Ashley Walker (University of Oregon) interviews author Dr. Efthymios Ziogos (Johns Hopkins Medicine) and expert Dr. Jennifer Williams (McMaster University) about the recent study by Ziogos et al. published in the Call for Papers Impact of Aging on CV System. Ziogos and co-authors used advanced MRI to assess coronary endothelial function noninvasively and without contrast in order to compare endothelial-depen ..read more

In this episode, Associate Editor Dr. Keith Brunt (Dalhousie University) interviews author Dr. Stacy Hunter (Texas State University) and expert Dr. Annet Kirabo (Vanderbilt University) about the new study by Hunter et al., which examined the impact of hot yoga on sodium-induced pressor responses and endothelial function of Black women. In a randomized control trial that combined the thermal stress of hot yoga and a salt challenge, the authors investigated human homeostatic regulation in terms of whole-body physiology, cardiorenal responses, ph ..read more

What is the impact of female sex hormones on obesity, diabetes, and vascular dysfunction? In this episode, Deputy Editor Dr. Zam Kassiri (University of Alberta) interviews authors Dr. Bruna Visniauskas and Dr. Minolfa Prieto (both at Tulane University School of Medicine), along with expert Dr. Glen Pyle (IMPART Network at Dalhousie Medicine) about the new study by Visniauskas et al.
