Restricting excessive cardiac action potential and QT prolongation: a vital role for IKs in human ventricular muscle [PDF]
, 2005 Background - Although pharmacological block of the slow, delayed rectifier potassium current (I-Ks) by chromanol 293B, L-735,821, or HMR-1556 produces little effect on action potential duration (APD) in isolated rabbit and dog ventricular myocytes, the ...

Potential for Dose Reduction in CT-Derived Left Ventricular Ejection Fraction: A Simulation Study
Tomography, 2023 Background: Measuring left ventricular ejection fraction (LVEF) is important for detecting heart failure, e.g., in treatment with potentially cardiotoxic chemotherapy. MRI is considered the reference standard for LVEF, but availability may be limited and

External radiotherapy of thyroid cancer [PDF]
, 2001 Differentiated thyroid cancer comprises papillary, mixed papillary-follicular and follicular adenocarcinomas. They are mostly hormone-sensitive and respond to thyroid-stimulating hormone (TSH) suppression. The standard treatment is total thyroidectomy. I-

Randomized preclinical study of machine perfusion in vascularized composite allografts
BJS (British Journal of Surgery), EarlyView., 2020 This study was designed to identify the optimum machine perfusion parameters for preservation of limbs before transplantation, and determine whether this was better than cold storage. Normothermic machine perfusion at a pressure of 70 mmHg (NMP‐70) provided superior preservation to cold storage after transplantation.

Automatic segmentation of the left ventricle cavity and myocardium in MRI data [PDF]
, 2006 A novel approach for the automatic segmentation has been developed to extract the epi-cardium and endo-cardium boundaries of the left ventricle (lv) of the heart. The developed segmentation scheme takes multi-slice and multi-phase magnetic resonance (MR)

Cats with thermal burn injuries from California wildfires show echocardiographic evidence of myocardial thickening and intracardiac thrombi. [PDF]
, 2020 Recent increases in the prevalence and severity of wildfires in some regions have resulted in an increased frequency of veterinary burn patients. Few studies exist regarding diagnostics and management of burn wounds in veterinary patients and current ...

Morphological Study of Chordae Tendinae in Human Cadaveric Hearts
Heart Views, 2015 Objectives: The chordae tendinae (CT) are strong, fibrous connections between the valve leaflets and the papillary muscles. Dysfunction of the papillary muscles and chordae is frequent.
