MULTIPLE VARIATIONS OF THE SUPERFICIAL JUGULAR VEINS: CASE REPORT AND CLINICAL RELEVANCE

Acta Medica, 2014
The jugular venous system constitutes the primary venous drainage of the head and neck. It includes a profundus or subfascial venous system, formed by the two internal jugular veins, and a superficial or subcutaneous one, formed by the two anterior and ...

Unilateral external jugular vein aneurysm in a dog

Journal of Veterinary Cardiology, 2022
An 11-month-old Staffordshire Bull Terrier was referred with a two-month history of fluctuating unilateral jugular groove swelling, which appeared to enlarge after exercise. There was no history of trauma. Multimodal imaging findings (using transdermal and transesophageal ultrasound and dual phase computed tomography angiography) were consistent with ...

A Single‐Cell Transcriptomic Atlas of the Ovine Rumen Microbiome Characterizes Lineage‐Specific Metabolic Shifts Associated with Host Heat Tolerance

Advanced Science, EarlyView.
An optimized single‐cell transcriptomic framework profiles over 60 000 cells to map the ovine rumen microbiome, partitioning the ecosystem into seven cross‐species functional clusters. In heat‐resistant hosts, a lineage‐specific metabolic shift in Anaerovibrio lipolyticus toward a highly glycolytic phenotype contributes to a “nutritional sparing ...

A novel rat model of pulmonary artery embolism and the application value of lung ultrasound B‐lines in early‐stage pulmonary embolism

Animal Models and Experimental Medicine, EarlyView.
We report a novel embolus‐induced PE rat model prepared via the inferior vena cava under ultrasound guidance. The embolus employed featured a tubular plastic casing filled with thrombus. By minimizing the contact surface between plasmin and thrombus, it effectively restrains the elevated plasmin activity in rats.

Safety and Feasibility of Magnetic Separation‐Based Blood Purification

Advanced NanoBiomed Research, EarlyView.
We present the preclinical biological safety and translational feasibility of a magnetic nanoparticle‐based extracorporeal blood purification platform for removal of disease‐causing blood factors. ISO 10993‐compliant studies and exaggerated worst‐case exposure models demonstrate efficient nanoparticle extraction (≥99.9%), favorable biocompatibility ...

Lepromatous phlebitis of the left external jugular vein [PDF]

BMJ Case Reports, 2012
A painless lump over the left lateral aspect of the neck was the sole presenting complaint of a 54-year-old gentleman. On examination, the lump was cord-like, non-tender, non-pulsatile and mobile (figure 1). There were no other lumps or elsewhere in the body.

Osteological correlates of the respiratory and vascular systems in the neural canals of Mesozoic ornithurines Ichthyornis and Janavis

The Anatomical Record, EarlyView.
Abstract In birds, the neural canal houses a variety of anatomical structures including the spinal cord, meninges, spinal vasculature, and respiratory diverticula. Among these, paramedullary diverticula and the extradural dorsal spinal vein may leave behind osteological correlates in the form of pneumatic foramina and fossae, and a bilobed geometry of ...
