Most sea urchin species are indirect developers, going through a larval stage called pluteus. The pluteus possesses its own nervous system, consisting mainly of the apical organ neurons (controlling metamorphosis and settlement) and ciliary band neurons (controlling swimming behavior and food collection). Additional neurons are located in various areas of the gut.

These have been considered dormant until recently when resting cells of Skeletonema marinoi were shown to assimilate nitrate and ammonium from the ambient environment in dark, anoxic conditions. Here, we show that resting cells of S.

- The "ribbon" structure of connected Golgi stacks is typically thought to exist only in vertebrates, but this study suggests it might have originated earlier in animal evolution.
- Researchers found ribbon-like structures in various metazoans, indicating that this architectural feature predates vertebrates and may be linked to processes like embryogenesis.
- The study proposes that the evolution of specific proteins (GRASP) may have facilitated the formation of these Golgi ribbons, which could have important biological roles that are still not fully understood.
The early identification of a subclinical rejection (SCR) can improve the long-term outcome of the transplanted kidney through intensified immunosuppression. However, the only approved diagnostic method is the protocol biopsy, which remains an invasive method and not without minor and/or major complications. The protocol biopsy is defined as the sampling of allograft tissue at pre-established times even in the absence of an impaired renal function; however, it does not avoid histological damage.

Objective: To evaluate the fecal bacterial microbiota at the time of diagnosis (T0) and after 1 month of therapy (T1) in cats diagnosed with lymphoplasmacytic enteritis (LPE) or cats with low-grade intestinal T-cell lymphoma (LGITL) and to compare these findings with those of healthy cats.
Animals: 5 healthy cats, 13 cats with LPE, and 7 cats with LGITL were prospectively enrolled between June 2020 and June 2021.
Methods: Fecal samples were collected at T0 and T1, and DNA was extracted for 16S ribosomal amplicon sequencing.
