Congenital anomalous bands at the proximal jejunum resulting in obstruction have been described sporadically in the literature and are otherwise rare. We present a case of an 8 year-old girl with a nine-month history of intermittent vomiting and no history of prior surgery. The imaging workup includes an abdominal ultrasound, a single contrast upper gastrointestinal series, and a dual contrast computed tomography of the abdomen and pelvis. Surgical intervention revealed the presence of dense bands at the proximal jejunum without evidence of malrotation. Our report reviews the embryology and radiologic findings of this entity using different imaging modalities.

Understanding vibrissal transduction has advanced by serial sectioning and identified afferent recordings, but afferent mapping onto the complex, encapsulated follicle remains unclear. Here, we reveal male rat C2 vibrissa follicle innervation through synchrotron X-ray phase contrast tomograms. Morphological analysis identified 5% superficial, ~32 % unmyelinated and 63% myelinated deep vibrissal nerve axons.

Lateral band snapping syndrome can be a debilitating condition involving the proximal interphalangeal (PIP) joint of the fingers. Although rare, it is thought to occur due to disruption of the finger extensor mechanism allowing inappropriate subluxation of the lateral bands over the PIP joint, leading to mechanical and painful symptoms.Here, we describe a woman in her early 40s with a painful, snapping PIP joint secondary to a work-related injury.

Intrasaccular flow disruption has become established for the treatment of wide necked and bifurcation aneurysms. The most successful current devices are the WEB (Microvention) and Contour (Stryker). The Artisse (Medtronic) is a novel intrasaccular device designed to treat a variety of aneurysm morphologies.

To understand karyotype variation in eight populations, detailed karyotypes were meticulously established using chromosomal measurements, fluorescence bands, and rDNA FISH signals. The number of 45S rDNA sites varies from one to five pairs per population, with the most common number per karyotype being four pairs. The 45S rDNA locus is predominantly located in the short arms and terminal regions of chromosomes, while the 5S rDNA locus is found mainly in the short arm and the terminal or proximal regions.
