Conformable Microelectrode Arrays Integrated with a Scoop‐Shaped Slide‐Well for Dynamic Electrophysiological Profiling of Patient‐Derived Cardiac Organoids

Advanced Science, EarlyView.
A flexible, ultrathin multi‐channel microelectrode array (MEA) conformally integrated onto a curved slide‐well enables stable electrical interfacing with 3D cardiac organoids. The geometry‐guided self‐alignment allows simultaneous recording of extracellular field potentials and contractile motion from irregular, beating tissues.

Systolic ejection murmurs and the left ventricular outflow tract in boxer dogs [PDF]

, 2007
Turbulence of various genesis in the left ventricular outflow tract (LVOT) causes systolic ejection murmurs. The prevalence of murmurs in adult boxer dogs is 50-80%, the majority of which are of low intensity.

Aberrant migration and surgical removal of a heartworm (Dirofilaria immitis) from the femoral artery of a cat. [PDF]

, 2018
A cat was evaluated for an acute-onset of right pelvic limb paresis. Thoracic radiographs revealed normal cardiac size and tortuous pulmonary arteries.

Optimization and verification of high‐fat diet formulation for establishing a rat model of obesity‐related precocious puberty

Animal Models and Experimental Medicine, EarlyView.
We identified 45% HFD as the optimal formulation to establish a juvenile rat model of obesity‐related precocious puberty. It elicits robust phenotypic (early vaginal opening, obesity), histological (advanced ovarian development), and endocrine (elevated HPG axis hormones) alterations, with leptin‐mediated GnRH secretion as a core mechanistic driver ...

Characterization and Normal Measurements of the Left Ventricular Outflow Tract by ECG-gated Cardiac CT: Implications for Disorders of the Outflow Tract and Aortic Valve. [PDF]

, 2012
RATIONALE AND OBJECTIVES: Studies suggest that electrocardiographically gated coronary computed tomographic angiography provides a clear definition of the left ventricular outflow tract (LVOT), and normal LVOT morphology may not be round, as assumed when

Dynamic left ventricular obstruction evoked by exercise: importance of outflow tract size [PDF]

European Journal of Echocardiography, 2009
We have read with interest the article by Zywica et al. 1 recently published in an issue of the European journal of Echocardiography. The authors analysed, in 300 patients referred for exercise echocardiography, the prevalence and predictive factors of dynamic left ventricular outflow tract obstruction on immediate post-exercise echocardiographic ...

Research progress on biomarkers of traumatic brain injury

Animal Models and Experimental Medicine, EarlyView.
Traumatic brain injury: From primary insult to secondary neuroinflammation and degeneration. Abstract Traumatic brain injury (TBI) is a common disorder of the nervous system and has become a leading cause of death and disability worldwide, imposing a substantial burden on patients and their social circles. Its main symptoms include dyskinesia, language

Late-onset dynamic outflow tract gradient in the setting of tako-tsubo cardiomyopathy: An interesting phenomenon with potential implications?

Indian Heart Journal, 2017
In clinical practice, dynamic left ventricular outflow tract obstruction (LVOTO) in the setting of tako-tsubo cardiomyopathy (TTC) has been regarded as an early-onset complication typically emerging in accordance with wall motion abnormalities.
