Heart, Lung and Circulation, 2011
A year-old patient presented with a painful right leg at the emergency department. Her medical history revealed persistent atrial fibrillation and congestive heart failure. The patient was on adequate warfarin treatment. At physical examination, she had a cold right leg without pulsations and a discoloured and patched skin.

The Hydrodynamics of Jellyfish Swimming
Annual Review of Marine Science, 2021Jellyfish have provided insight into important components of animal propulsion, such as suction thrust, passive energy recapture, vortex wall effects, and the rotational mechanics of turning. These traits are critically important to jellyfish because they must propel themselves despite severe limitations on force production imposed by rudimentary ...

Proceedings of the 21st International Middleware Conference, 2020
Multi-version concurrency control is a widely employed concurrency control mechanism, as it allows non-blocking accesses while providing isolation among transactions. However, maintaining multiple versions increases the latency for both point lookups and ranged retrievals because of the overhead in finding the right version.

Jellyfish Model for Ototoxicity
Otology & Neurotology, 2015Pharmacologic ototoxicity is well described in the medical literature, yet efficient screening models are lacking. Aurelia aurita ephyrae, transparent jellyfish with identifiable hair cells, could be an effective model. Structural changes readily manifest behaviorally, and hair cells are easily stained and observed.

Granulomatous jellyfish dermatitis
JDDG: Journal der Deutschen Dermatologischen Gesellschaft, 2007SummaryThe induction of a granulomatous inflammation by jellyfish toxins is rare. More typically, acute toxic and urticarial reactions are seen. An 11‐year‐old boy developed a striated urticarial erythema on the left cheek after contact with a gelatinous mass while swimming in the sea in Croatia.

Jellyfish envenomation syndromes
Journal of the American Academy of Dermatology, 1986Jellyfish venoms are complex mixtures of polypeptides and enzymes pathogenic to man by means of their toxic or antigenic properties. With newer technology, more therapeutic agents will become available to treat the various envenomation syndromes caused by these animals.

The flow induced by a jellyfish
Journal of Visualization, 2008The purpose of this study is to understand the propulsion mechanism of a jellyfish during its swimming. We observed the motion of a jellyfish (Aurelia aurita) by a motion-capture camera, and measured the vector field of flow around a jellyfish by using a PIV (Particle Image Velocimetry) measurement. A jellyfish is considered to be principally propelled

Ophthalmology, 1992
Corneal stings from the sea nettle (Chrysaora quinquecirrha) indigenous to the Chesapeake Bay are usually painful but self-limited injuries, with resolution in 24 to 48 hours.Five patients who developed unusually severe and prolonged iritis and intraocular pressure elevation after receiving corneal sea nettle stings were followed for 2 to 4 years ...

Beware the malignant jellyfish
The Annals of Thoracic Surgery, 2001Small pleural effusions that cannot be assessed by thoracentesis prior to surgery may represent a diagnostic challenge in the patient with a resectable, non-small cell cancer of the lung. Even if the effusion is drained preoperatively and analyzed, the cytology may be falsely negative.

Can a Jellyfish Remember Being a Jellyfish?
Can an experience survive being “reborn”? The immortal jellyfish, Turritopsis dohrnii, is one of the few known organisms capable of reversing its life cycle, returning from an adult medusa to a juvenile polyp through a remarkable process of developmental rejuvenation.openaire +1 more source
