The circulatory system of represents an easily amenable genetic model whose analysis at different levels, , from single molecules up to functional anatomy, has provided new insights into general aspects of cardiogenesis, heart physiology and cardiac aging, to name a few examples. In recent years, the heart has also attracted the attention of researchers in the field of biomedicine. This development is mainly due to the fact that several genes causing human heart disease are also present in , where they play the same or similar roles in heart development, maintenance or physiology as their respective counterparts in humans. This review will attempt to briefly introduce the anatomy of the circulatory system and then focus on the different cell types and non-cellular tissue that constitute the heart.

A carnitine transporter at the blood-brain barrier modulates sleep via glial lipid metabolism in .
Proc Natl Acad Sci U S A

Department of Cell Biology, Emory University, Atlanta, GA 30322.
To regulate brain function, peripheral compounds must traverse the blood-brain barrier (BBB), an interface between the brain and the circulatory system. To determine whether specific transport mechanisms are relevant for sleep, we conducted a BBB-specific inducible RNAi knockdown (iKD) screen for genes affecting sleep in . We observed reduced sleep with knockdown of solute carrier , a carnitine transporter, as determined by isotope flux.

We analyse mathematical models of blood flow in two simple vascular networks in order to identify structural features that lead to the formation of multiple equilibria. Our models are based on existing rules for blood rheology and haematocrit splitting. By performing bifurcation analysis on these simple network flow models, we identify a link between the changing flow direction in key vessels and the existence of multiple equilibria.

Background: In previous efforts, health-related quality of life (HRQoL) improved for individuals at high risk of type 2 diabetes and cardiovascular disease after participation in community-based lifestyle interventions (LI) with a moderate-to-vigorous physical activity (MVPA) movement goal.
Purpose: It is unknown whether HRQoL improves with LI when the primary movement goal is to reduce sedentary behavior. HRQoL changes were examined among adults with overweight and prediabetes and/or metabolic syndrome randomized to a 12-month Diabetes Prevention Program-based Group Lifestyle Balance (DPP-GLB) community LI work with goals of weight-loss and either increasing MVPA (DPP-GLB) or reducing sedentary time (GLB-SED).
Prognostic utility of assessing ventricular-arterial coupling in arterial hypertension and cardiovascular diseases.

The assessment of myocardial function and its coupling with the arterial system, called ventricular-arterial coupling (VAC), is of paramount importance in many clinical fields, from arterial hypertension, which is the main cause of cardiovascular diseases and death, to heart failure. VAC has been the subject of studies for several decades both from an energetic cost and the impact it can exert on cardiovascular performance. Although more attention has been paid to the relationship between the left ventricle and the left arterial circuit in compromised hemodynamic stages, VAC has aroused interest in many other aspects of study, from its application in pathologies of the right sections of the heart to its clinical impact in prevention and cardiovascular risk factors.

Background: Chronic limb-threatening ischemia (CLTI) in patients with chronic kidney disease (CKD) has a high risk of poor outcomes. We aimed to compare the outcomes of lower extremity revascularization in patients with CLTI stratified by CKD severity in patients enrolled in the prospective, randomized Best Endovascular vs Best Surgical Therapy in Patients with CLTI (BEST-CLI) trial.
Methods: The BEST-CLI trial dataset was queried to categorize patients into three groups according to CKD stage.
