UCP2 modulates cardiomyocyte cell cycle activity, acetyl-CoA, and histone acetylation in response to moderate hypoxia

JCI Insight, 2022
Developmental cardiac tissue is regenerative while operating under low oxygen. After birth, ambient oxygen is associated with cardiomyocyte cell cycle exit and regeneration. Likewise, cardiac metabolism undergoes a shift with cardiac maturation.

Three-dimensional structure of the flow inside the left ventricle of the human heart

, 2013
The laboratory models of the human heart left ventricle developed in the last decades gave a valuable contribution to the comprehension of the role of the fluid dynamics in the cardiac function and to support the interpretation of the data obtained in ...

Regional differences in APD restitution can initiate wavebreak and re-entry in cardiac tissue: A computational study [PDF]

, 2005
Background Regional differences in action potential duration (APD) restitution in the heart favour arrhythmias, but the mechanism is not well understood.

Learning the cardiac cycle with a puzzle

The FASEB Journal, 2012
In order to teach the phases of cardiac cycle for students from Dental School we developed a puzzle, with one table of 5 columns: 1. Phase of cardiac cycle, 2. Atrial state, 3. Ventricular state, 4. Atrio ventricular valves and 5. Pulmonary and aortic valves, painted in different colors: white, blue, green, yellow and pink, respectively. Figures of the

An Updated Rounds Checklist to Increase Appropriate Use of Telemetry Monitoring [PDF]

, 2015
Background: Telemetry monitoring is an essential tool to monitor cardiac electrical activity. Its overuse is costly in time and resources and leads to subsequent testing and treatments that are not necessary for the patient and, in addition, healthcare ...
