Physiological Control of Realheart Total Artificial Heart

Artificial Organs, EarlyView.
This study evaluates the Realheart Total Artificial Heart's preload‐based physiological controller, which dynamically adjusts heart rate and stroke volume to mimic the heart's natural responses during sleep, rest, and exercise using a hybrid mock circulation loop of the cardiovascular system.

New Findings on Pulsatile ECMO: Verification of the Potential to Improve Antithrombogenicity of a Membrane Oxygenator Using Pump‐Generated Pulsatile Flow in an Innovative Animal Model

Artificial Organs, EarlyView.
Compared to the steady flow circuit, the pulse flow circuit showed a clear trend of less thrombus formation inside the membrane oxygenator. ABSTRACT Background Extracorporeal membrane oxygenation (ECMO) provides mechanical circulatory and respiratory support.

Effect of anticholinergic eye drops on intraorbital, periorbital and brain pulsation power

Acta Ophthalmologica, EarlyView.
Abstract Purpose The study aims to investigate the effect of pharmacologically reducing parasympathetic activity on ocular and cerebral pulsations, inspired by recent discoveries of a glymphatic‐like system in the eye driven by physiological pulsations.

Morphological variations of the ovarian follicles and oviduct of commercial Lohmann Brown and indigenous Potchefstroom Koekoek breeds

Acta Zoologica, EarlyView.
Abstract Egg laying begins with the orderly development of follicles in the chicken ovaries and transportation through the oviduct with deposition of nutrients until the eggs are produced. However, the ovarian follicles and oviduct morphology of Lohmann Brown and Potchefstroom Koekoek laying hens have not yet been studied.

Carotid Artery Disease

2012
Familiarity with the extra- and intracranial vessel anatomy is decisive for successful treatment of carotid artery disease. The right common carotid artery originates from the bifurcation of the brachiocephalic trunk, while the left one arises directly from the aortic arch. The common carotid artery does not have any side branches. Usually at the level

Carotid artery disease and cognitive impairment

Journal of the Neurological Sciences, 2012
The term neurologic symptom usually relates to the loss of motor or sensory functions; cognitive deficit is mostly unrecognized in patients with severe carotid stenosis. In large population studies carotid stenosis has been shown as independent risk factor for mild cognitive impairment (MCI) and it was not due to underlying vascular risk factors.
