NiMoO4 nanosheets modified carbon paste electrode for simultaneous determination of epinine and dobutamine

Journal of Electrochemical Science and Engineering
In this work, a carbon paste electrode was modified with ionic liquids and NiMoO4 nanosheets (NMs/IL/CPE) for voltammetric epinine detection. The NMs/IL/CPE showed good electro­catalytic activity for epinine oxidation compared to unmodified CPE.

A Heart Stopping Case of the Bezold-Jarisch Reflex

Case Reports in Cardiology, 2015
The Bezold-Jarisch reflex is a parasympathetic reflex induced by intense mechanical stimulation of the ventricular myocytes. Exceptionally, cases have been described in patients receiving dobutamine infusion during a stress echocardiography.

Dobutamine does not influence inflammatory pathways during human endotoxemia

, 2006
OBJECTIVE: Catecholamines have anti-inflammatory and anticoagulant properties. Dobutamine is a synthetic catecholamine frequently used in patients with septic myocardial dysfunction.

Wall motion assessment by feature tracking in pediatric patients with coronary anomalies undergoing dobutamine stress CMR

Frontiers in Cardiovascular Medicine
BackgroundLeft ventricular (LV) wall motion assessment is an important adjunct in addition to perfusion defects in assessing ischemic changes. This study aims to investigate the feasibility and utility of performing feature tracking (FT) in pediatric ...

Cardiac Risk Assessment before Vascular Surgery: A Prospective Study Comparing Clinical Evaluation, Dobutamine Stress Echocardiography, and Dobutamine Tc-99m Sestamibi Tomoscintigraphy

, 1997
peer reviewedPreoperative evaluation for cardiac risk assessment before peripheral vascular surgery remains controversial. Between January and June 1994, a prospective open study was carried out in 156 patients scheduled for elective vascular procedures (

Dobutamine-induced alterations in internal carotid artery blood flow and cerebral blood flow in healthy adults

Brain Research Bulletin
Purpose: Dobutamine, a sympathomimetic agent, is widely used clinically, influencing cardiac output, heart rate (HR), and blood pressure (BP), which may impact cerebral blood flow (CBF), critical for brain metabolism.

Dobutamine enhances both contractile function and energy reserves in hypoperfused canine right ventricle

, 2000
Although the β1-adrenergic agent dobutamine is used clinically to provide inotropic support to the failing myocardium, it could jeopardize the myocardium by depleting energy reserves. This investigation delineated the contractile and energetic effects of

Uso de dobutamina para la inducción de arritmias durante estimulación eléctrica programada del corazón Dobutamine use for arrythmia induction during electrical programmed heart stimulation

Revista Colombiana de Cardiología, 2006
Introducción: el isoproterenol es el fármaco que se ha empleado tradicionalmente para incrementar la inducción de arritmias cuando durante la estimulación eléctrica programada del corazón en condiciones basales, no se logra su inducción. La dobutamina es
