2025
Borderline Personality Disorder is a complex and multifaceted mental health condition characterized by pervasive instability in interpersonal relationships, self-image, emotions, and impulse control. This instability manifests in extreme emotional reactions, fear of abandonment, and self-destructive behaviors. The disorder significantly impacts daily functioning, often leading to distress in both personal and professional domains. Genetic and Environmental Contributions Borderline Personality...

We present a protocol of personalized script-driven trauma-related imagery and clinical assessments within a comparison design for investigating peritraumatic dissociation (PD), psychophysiological reactions, i.e. heart rate (HR) and skin conductance (SC), and psychological features of often severely traumatized individuals with borderline personality disorder (BPD).

Classically, the endocardium of the mouse embryonic valve primordium has been analyzed using transversal, coronal, or sagittal sections. Our novel approach for en face, two-dimensional imaging of the endocardium at valvulogenic regions allows planar polarity and cell rearrangement analysis of the endocardium during valve development.

This protocol describes a method for the photoconversion of Kaede fluorescent protein in endocardial cells of the living zebrafish embryo that enables the tracking of endocardial cells during atrioventricular canal and atrioventricular heart valve development.
FAQs
Ultrasound visualization depends on the acoustic boundary between the blood pool and myocardium. When waves encounter this interface, reflected signals create a visible line that can be followed along the chamber interior. The clarity of that line determines how confidently an operator can identify chamber limits and use them for subsequent structural and functional measurements.
Tissue contrast, imaging angle, and blood-pool definition strongly influence how clearly the endocardial border appears. Poor contrast can make the boundary difficult to distinguish, while an unfavorable imaging angle may reduce the usefulness of reflected signals. These factors directly affect the reliability of tracing and the accuracy of measurements derived from the visible chamber boundary.
A clearly defined blood pool helps separate the chamber cavity from the myocardium, making the inner chamber limits easier to identify. This distinction supports more consistent assessment of chamber dimensions and ventricular volume. It also helps the observer follow the boundary when evaluating wall thickness or comparing motion in different myocardial regions.
When conventional echocardiographic images do not show the boundary clearly, ultrasound contrast agents may improve endocardial border delineation. Better visualization can make chamber tracing easier and increase the reliability of measurements based on that tracing. Their role is particularly relevant when limited blood-pool definition prevents confident assessment of cardiac structure or function.
During echocardiographic assessment, the visible boundary can be identified and traced to establish the limits of the cardiac chamber. Those traced limits support measurements of chamber dimensions and ventricular volume, while the relationship between the border and myocardium helps assess wall thickness. Accurate border identification therefore connects image interpretation with quantitative cardiac evaluation.
Endocardial border assessment contributes to evaluating cardiac performance by supporting measurements of chamber size, ventricular volume, and wall thickness. It also provides a reference for judging regional wall motion, allowing areas of abnormal movement to be recognized. These structural and functional observations help clinicians assess the heart and detect abnormalities during echocardiographic examination.
