A tomographic microscopy-compatible Langendorff system for the dynamic structural characterization of the cardiac cycle [PDF]
Frontiers in Cardiovascular Medicine, 2022 IntroductionCardiac architecture has been extensively investigated ex vivo using a broad spectrum of imaging techniques. Nevertheless, the heart is a dynamic system and the structural mechanisms governing the cardiac cycle can only be unveiled when ...

Active tactile discrimination is coupled with and modulated by the cardiac cycle [PDF]
eLife, 2022 Perception and cognition are modulated by the phase of the cardiac signal in which the stimuli are presented. This has been shown by locking the presentation of stimuli to distinct cardiac phases.

Cardiac Cycle Affects the Asymmetric Value Updating in Instrumental Reward Learning [PDF]
Frontiers in Neuroscience, 2022 This study aimed to investigate whether instrumental reward learning is affected by the cardiac cycle. To this end, we examined the effects of the cardiac cycle (systole or diastole) on the computational processes underlying the participants’ choices in ...

Parkinson’s Disease and the Cardiac Cycle: A Rapid Literature Review and Case Series [PDF]
Life, 2023 Background and Objectives: Cardiac function in patients with Parkinson’s Disease (PD) is not well understood. We conducted a review of the literature to summarize all available data on the cardiac cycle in patients with PD and followed up the review with

Dynamic Changes in the Aorta During the Cardiac Cycle Analyzed by ECG-Gated Computed Tomography [PDF]
Frontiers in Cardiovascular Medicine, 2022 BackgroundTo characterize the difference in aortic dimensions during the cardiac cycle with electrocardiogram (ECG)-gated computed tomography angiography (CTA) and to determine whether other parameters in comparison to diameter could potentially provide ...

Electrokymographic Studies of the Normal Cardiac Cycle [PDF]
Circulation, 1950 Normal subjects were studied by employing two electrokymograms simultaneously. By comparing the sequence of events in the carotid pulse, auricle and ventricle, measurements were made of the phases of the cardiac cycle. The normal electrokymogram is discussed and illustrated.

Automated segmentation on the entire cardiac cycle using a deep learning work-flow [PDF]
arXiv, 2018 The segmentation of the left ventricle (LV) from CINE MRI images is essential to infer important clinical parameters. Typically, machine learning algorithms for automated LV segmentation use annotated contours from only two cardiac phases, diastole, and ...

Over expression of Plk1 does not induce cell division in rat cardiac myocytes in vitro. [PDF]
PLoS ONE, 2009 BACKGROUND:Mammalian cardiac myocytes withdraw from the cell cycle during post-natal development, resulting in a non-proliferating, fully differentiated adult phenotype that is unable to repair damage to the myocardium, such as occurs following a ...
