Cellular composition of the adult zebrafish (Danio rerio) optic tectal cortex was examined in this study. Morphological techniques such as 1 μm thick serial plastic sections stained with osmium tetroxide and toluidine blue, modified rapid Golgi silver impregnation, GFAP immunohistochemistry, confocal microscopy, as well as scanning and transmission electron microscopy were used. Neuronal and glial components are described and the layers of the cortex are revisited. Specific neuronal arrangements as well as unique glial/ependymal cells are described. A three dimensional rendering of the astrocytic fiber arrangement in the marginal zone is presented and a composite drawing summarizes the cellular composition of the optic tectum.

Exopolysaccharides (EPS) produced by lactic acid bacteria with immunomodulatory potential are promising natural food additives. This study employs small-scale, 250 mL bioreactors combined with a central composite design to optimise two important bioprocess parameters, namely temperature and airflow, to achieve high yields of biomass and EPS from Lacticaseibacillus rhamnosus LRH30 (L. rhamnosus LRH30).

Background: Liver cirrhosis represents a critical stage of chronic liver disease, characterized by progressive liver damage, cellular dysfunction, and disrupted cell-to-cell interactions. Glycosylation, an essential post-translational modification, significantly influences cellular behavior and disease progression. Its role in cirrhosis at the single-cell level remains unclear, despite its importance.

Background And Aim: Creeping fat (CF) in Crohn's disease (CD) is characterized by hyperplastic mesenteric adipose tissue (MAT) encasing fibrotic intestinal segments. CF exhibits disruptions in microbiota and lipid metabolism, particularly in lysophospholipids (LPC). This study aims to elucidate the impact of LPC on adipogenic differentiation of mesenchymal stem cells in CF and its effects on immune defense functions in the differentiated adipocytes.

Objective: This study investigated the use of oral rinse solutions formulated with boron-containing compounds, known for their antibacterial activity, as an alternative to chlorhexidine (CHX).
Material And Method: Boron nitride (BN), boric acid (BA) and sodium borate (SB) were used in the study. BN was used in nanosuspension (BN-NS) due to its low solubility in water.

Melanoma is more aggressive in male patients than female ones and this is associated with sexual dimorphism in immune responses. Taking into consideration the impact tumour metabolic alterations in affecting the immune landscape, we aimed to investigate the effect of the sex-dependent metabolic profile of melanoma in re-shaping immune composition. Melanoma is characterised by Warburg metabolism, and secreted lactate has emerged as a key driver in the establishment of an immunosuppressive environment.
