Does immunolocalization of serotonin in Onychophora argue against segmental ganglia being an ancestral feature of arthropods?
Our histological findings and immunolocalization experiments highlight the medullary organization of the onychophoran nerve cord and argue against segmental ganglia of the typical euarthropodan type being an ancestral feature of Onychophora. These results contradict a priori assumptions of segmental ganglia being an ancestral feature of arthropods and, thus, weaken the traditional Articulata hypothesis, which proposes a sistergroup relationship of Annelida and Arthropoda.
We propose that EUK-134 reduces renal I/R injury not only via reduction of oxidative stress, but also by reducing nitrosative stress caused by renal I/R.
