Article Abstract
The growth of zebrafish's vessels can be used as an indicator of the vascular development process and to study the biological mechanisms. The three-dimensional (3D) structures of zebrafish's trunk vessels could be imaged by state-of-art light-sheet fluorescent microscopy with high efficiency. A large amount of data was then produced. Accurate segmentation of these 3D images becomes a new bottleneck for automatic and quantitative analysis. Here, we propose a Multi-scale 3D U-Net model to perform the segmentation of trunk vessels. The segmentation accuracies of 82.3% and 83.0%, as evaluated by the IoU (Intersection over Union) parameter, were achieved for intersegmental vessels and the dorsal longitudinal anastomotic vessels respectively. The growth of zebrafish vasculature from 42-62 hours was then analyzed quantitatively.

Neutrophilic Urticarial Dermatosis in Systemic Lupus Erythematosus: A Diagnostic Challenge.

Dermatology, Temple University Hospital, Philadelphia, USA.
Neutrophilic urticarial dermatosis (NUD) is a rare condition that clinically resembles urticaria but is distinguished histopathologically. Given the overlap of clinical and histopathologic features between NUD, urticaria, and urticarial vasculitis (UV), distinguishing between these diagnoses is crucial, as their treatments differ significantly. A 47-year-old woman with systemic lupus erythematosus (SLE) presented with a mildly pruritic, burning rash for one week.

Resistance arteries, which include small arteries and arterioles, play essential roles in regulating blood pressure and tissue perfusion. Dysfunction in these arteries can lead to various cardiovascular conditions such as hypertension, atherosclerosis, and heart failure, as well as neurovascular conditions. The examination of human resistance arteries is crucial for understanding cardiovascular disease mechanisms and developing targeted therapeutic strategies.

Background: Umbilical cord hemorrhage (UCH) is a rare but catastrophic obstetric emergency associated with nearly 50% fetal mortality, and its precise pathogenic mechanisms remain elusive in clinical practice. The pathophysiological cascade involves hemorrhagic expansion from ruptured umbilical vessels predominantly the umbilical vein which generates compressive forces on adjacent umbilical arteries within the constrained Wharton's jelly. This acute vascular compromise precipitates the sudden cessation of fetoplacental circulation, culminating in irreversible hypoxic-ischemic injury.

Background: Anatomical variations of the aorta-celiac trunk are highly relevant in abdominal surgery and interventional radiology. Traditional CT-A images may fall short in conveying these complex structures. This study investigates whether patient-specific 3D models can enhance resident-level understanding of aorta-celiac trunk anatomy and support surgical education.

Anatomical and clinical records were analyzed to identify cases of anomalous origins of the main renal artery. Instead of typically branching from the abdominal aorta at the vertebral level of L1-L2, the main renal artery can originate from the thoracic aorta, the inferior abdominal aorta (below the L2 vertebra), or from nearby arterial vessels such as the celiac trunk, superior mesenteric artery, inferior mesenteric artery, or common iliac artery.
