Holobiont nitrogen control and its potential for eutrophication resistance in an obligate photosymbiotic jellyfish

open access: yesMicrobiome, 2021
Background Marine holobionts depend on microbial members for health and nutrient cycling. This is particularly evident in cnidarian-algae symbioses that facilitate energy and nutrient acquisition.

Biodiversity and spatial distribution of medusae in the Magellan Region (Southern Patagonian Zone)

open access: yesLatin American Journal of Aquatic Research, 2014
Epipelagic medusae collected in the Magellan Region (Southern Patagonian Zone) during spring 2009 were analyzed. A total of 27 species of medusae were identified (25 hydromedusae and 2 scyphomedusae).

Three‐Dimensional Biomimetic Aerogel Conduits with Electro‐Ionic‐Immune Coupling Reverse the Pathological Cascade of Spinal Cord Injury

open access: yesAdvanced Functional Materials, Volume 36, Issue 63, 6 August 2026.
A biomimetic aerogel conduit was engineered from a nanofiber of gelatin/poly(l‐lactic acid) doped with polypyrrole nanoparticles, integrated with tannic acid and Mg2+. This “electro‐ionic‐immune” strategy mimicked spinal cord properties, reduced calcium overload, inflammation, oxidative damage, promoted neural stem cell differentiation, suppressed ...

Upstream Foraging by Medusae

open access: yes, 2006
Convergence upon similar morphological traits is common among predators feeding on similar prey in similar environments. Aboral placement of tentacles during swimming appears to be such a trait and has evolved in parallel among several medusan lineages ...

Bleeding Stomal Varices and Vascular Interventional Radiology Management: A Case Report

open access: yesClinical Case Reports, Volume 14, Issue 8, August 2026.
ABSTRACT Stomal varices are a rare but life‐threatening complication of portal hypertension. While multiple approaches are used to treat these varices, clinicians often face significant diagnostic and therapeutic challenges. A 55‐year‐old woman with a history of cirrhosis and low rectal cancer presented with massive stomal variceal bleeding requiring ...

Associations between fishes and medusae

open access: yes, 2023
U radu su predstavljeni fakultativni simbiotski odnosi različitih vrsta riba i meduza iz reda Schypozoa. Odnosi koji ostvaruju ribe i meduze mogu biti obostrano korisni (mutualizam), korisni samo za jednu vrstu (komenzalizam), a u nekim slučajevima je ...

Propofol‐Facilitated Recovery Sleep Modulates Cognitive Function via Slow Oscillation‐Spindle Coupling After Acute Sleep Deprivation in Rats

open access: yesCNS Neuroscience &Therapeutics, Volume 32, Issue 8, August 2026.
This study examined how propofol‐supported recovery sleep shapes cognitive and sleep‐EEG outcomes after 48‐h SD. Rats received Barnes maze, 2‐h and 24‐h NOR testing, cortical EEG/EMG recording, and NKCC1/KCC2 expression analysis. Propofol increased slow‐oscillation density and restored precise SO–spindle alignment, accompanied by a shift in NKCC1/KCC2 ...
