Effect of αα2-adrenoceptor stimulation on the isolated rat heart after acute myocardial infarction

open access: yesКардиоСоматика
Background: α2-Adrenoceptors (α2-ARs) are a family of G protein–coupled receptors. They are located on presynaptic membranes of adrenergic fibers, postsynaptic membranes of cardiomyocytes and vascular smooth muscle cells, as well as in the peripheral and

Angina de Prinzmetal Angina de Prinzmetal Prinzmetal's angina

open access: yesArquivos Brasileiros de Cardiologia, 2009
Essa síndrome é causada por um espasmo focal de uma artéria coronária epicárdica, levando a isquemia miocárdica grave. Embora freqüentemente acredite-se que o espasmo ocorra em artérias sem estenose, muitos pacientes com angina de Prinzmetal apresentam ...

Direct effects of glucose administration on heart rate, myocardial contraction, and duration of cardiac cycle in frog's heart

open access: yesJournal of the Practice of Cardiovascular Sciences, 2018
Background: Recent and emerging evidences show that glucose ingestion causes prolonged Q-T interval and can trigger arrhythmia. Objective: The objective of this study is to examine the effects of administration of glucose solutions on the heart rate ...

Life‐Threatening Bradycardia in Anti‐NMDA‐Receptor Encephalitis and a Novel Use for Permanent Pacing

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Background Pediatric anti‐NMDA receptor encephalitis (pNMDARE) is an autoantibody‐mediated disorder that can cause severe autonomic dysfunction, including symptomatic bradycardia and asystole. Dysautonomia can last for years, making it very challenging to manage.

3D (Bio) Printing Combined Fiber Fabrication Methods for Tissue Engineering Applications: Possibilities and Limitations

open access: yesAdvanced Functional Materials, EarlyView.
Biofabrication aims at providing innovative technologies and tools for the fabrication of tissue‐like constructs for tissue engineering and regenerative medicine applications. By integrating multiple biofabrication technologies, such as 3D (bio) printing with fiber fabrication methods, it would be more realistic to reconstruct native tissue's ...

Changes in left atrial deformation in hypertrophic cardiomyopathy: Evaluation by vector velocity imaging. [PDF]

open access: yes, 2012
OBJECTIVES: Hypertrophic cardiomyopathy (HCM) represents a generalized myopathic process affecting both ventricular and atrial myocardium. We assessed the global and regional left atrial (LA) function and its relation to left ventricular (LV) mechanics ...
