Cerebral Small Vessel Disease
Wednesday May 21, 2025
Wednesday May 21, 2025
What is cerebral small vessel disease and why is it such a critical area of research? In this episode, Associate Editor Dr. Scott Earley (University of Rochester) interviews author Dr. Anne Joutel (Université Paris Cité, Institute of Psychiatry and Neuroscience of Paris, INSERM) about the pathogenic diagnosis and molecular basis of cerebral small vessel disease (cSVD). Classified into two categories, cerebral amyloid angiopathy (CAA) and nonamyloid cSVD, cSVD is a major health problem responsible for about 25% of ischemic strokes, the vast majority of spontaneous intracerebral hemorrhage, and about 20% of all dementia cases. What role does the presence of lesions in small vessels play in exacerbating the burden of neurodegenerative diseases such as Alzheimer’s Disease? What is “silent cSVD” and how common is it? Listen now to find out more.

Tuesday May 20, 2025
In this episode, Dr. Jan Born (University of Tübingen) interviews his colleague and author Dr. Andreas Nieder (University of Tübingen) about his recent Review in Physiological Reviews on mathematical reasoning that incorporates neurobiology, comparative physiology, and neurophysiology. Mathematical skills can be described as falling into symbolic (arithmetic, number theory) and non-symbolic (set size) representations of numerical quantities. Infants as young as 2 days old can discriminate set size, for example, distinguishing between four dots and eight dots. And then, of course, there is the fascinating concept of zero, which is “rather like the eccentric uncle in the series of numbers,” as Dr. Nieder says. Understanding the concept of zero as the absence of something, represented as a number, is critical to understanding all other numbers. How does all of this work in the brain? Listen and find out.

Thursday Dec 05, 2024
In the episode, Dr. Sadis Matalon (University of Alabama Birmingham) interviews Dr. Catherine Dulac (Howard Hughes Medical Institute, Center for Brain Science, Harvard University) about the new Review in Physiological Reviews by Kaplan et al., which explores the neural basis of the complex social behavior of parenting. Parenting behavior is absolutely essential for the development of human beings and animal species. All humans and animals will experience the impact of parenting behavior on their lives, and parenting behavior is far more complex than simply the care of others. Parenting behavior is a unique physiological state that affects infant-to-adult interactions and adult-to-adult interactions, as well as a wide range of physiological changes related to food intake, sleep, and mood. We discuss essential questions related to the prevalence of postpartum depression disorder, genetic and environmental factors affecting the control of parenting behavior, and whether parenting behavior can improve over time with experience. Listen to this fascinating conversation to learn more.

Proteomics of the Heart

Thursday Nov 21, 2024
In the episode, Dr. Carol Ann Remme (University of Amsterdam) and Dr. Sadis Matalon (University of Alabama Birmingham) interview Dr. Jenny Van Eyk (Cedars-Sinai) about the Review in Physiological Reviews by Karpov et al. that dives into proteomics of the heart. Given that proteins are the building blocks of life, studying only genetic data or RNAseq data may offer researchers a somewhat narrow view. Proteomics looks broader, and broader is better, according to Dr. Van Eyk. However, this means that rigor at the proteomic technology level is critically important. Because the field of proteomics offers many different tools, using proteomics to study the heart necessitates matching the research question to the right tool. Dr. Van Eyk encourages researchers to develop a well-defined research question and then match it to the proteomics technology that is most appropriate, so that the output is as useful as possible. Pushing research to new frontiers allows researchers to find discoveries they never expected. Listen now and learn more.

Thursday Apr 25, 2024
In our latest episode, Dr. Farrah Kheradmand (Baylor College of Medicine) interviews Dr. Kevin Harrod (University of Alabama at Birmingham) about his article by Patton et al. on community-acquired bacterial coinfections and COVID-19. In the early days of the pandemic when physicians were treating critically ill COVID patients, there was no standard definition for bacterial coinfections in this cohort. However, as the field has moved forward with understanding how bacterial coinfections contribute to the mortality of COVID patients, Dr. Harrod and co-authors have worked to refine the definition of bacterial coinfections to provide a more unified way to report the prevalence of this important clinical problem. While it is often necessary to treat critically ill hospitalized COVID patients with antibiotics before sampling or culture results, Dr. Harrod and co-authors identify that this may mask the true prevalence of bacterial coinfections. Listen as Dr. Kheradmand and Dr. Harrod discuss linkages between carriage, viral infection, and secondary bacterial infections, as well as the pathophysiological ways that fungi may coinfect COVID patients. Are patients with underlying cystic fibrosis more prone to COVID infection? Listen now to learn more.
