Figure Lengend Snippet: Effect of treatments on neuronal and glial function biomarkers in the prefrontal cortex. (A) BDNF mRNA fold change and (B) GFAP mRNA fold change. Data are represented as mean ± SEM ( n = 7). One-way ANOVA followed by Tukey’s post hoc test. # = vs. Control; $ = vs. SI; @ = vs. SI&RUT-SeNPs; * = vs. SI&OLA; P < 0.05.

Article Snippet: To evaluate astrocytic activation and neuronal survival, paraffin embedded cortical sections were subjected to IHC staining targeting glial fibrillary acidic protein (GFAP) (Cat. No. NB300-141, 1:600, Novus Biologicals, Centennial, CO, USA) and nuclear factor Kappa-B (NF-kB) (Cat. No. NB100-56712, 1:200, Novus Biologicals, Centennial, CO, USA).

Figure Lengend Snippet: RUT-SeNPs protect against GFAP staining in the prefrontal cortex of rats with SI. Photomicrographs of the prefrontal cortex from each group. GFAP immunoreactivity was detected in tissues using DAB chromogen, resulting in a brown color (arrow) (DAB, X400, Scale bar = 50 µm). The control group (A) had normal cortical anatomy and mild GFAP staining. The SI (B) and SI&Na2SeO3-treated (E) groups showed strong GFAP immunostaining. In contrast, the (C) SI&OLA, (D) SI&RUT, and (F) SI&RUT-SeNP-treated groups demonstrated decreased GFAP staining. (G) Quantitative analysis of immunostaining area % for GFAP was expressed as mean ± S.E.M ( n = 7). Statistical analysis by one-way ANOVA with Tukey’s post hoc test. # = vs. Control; $ = vs. SI; @ = vs. SI&RUT-SeNPs; * = vs. SI&OLA; P < 0.05.

Article Title: Long-term brain pressure monitoring via a discrete microimplant; a first-in-human safety and initial efficacy trial in adults and children with hydrocephalus

doi: 10.1038/s41467-026-70864-8

Figure Lengend Snippet: A Immunohistochemistry of sheep brain tissue of the round shunt tubing adjacent to the sensor at 6 months post implantation (scale bar 2.5 mm) (6 sheep had histology performed). Green staining shows neurons stained with NeuN and indicates no widespread neuronal loss. Yellow shows quiescent microglia (IBA-1), indicating stabilisation of the tissue response at 6 months post-implantation. Pink shows astrocytes (GFAP) indicating minimal glial encapsulation. B Schematic showing the placement of the sensor directly within the parenchyma via a separate burr hole from the shunt. C Post-operative MRI image illustrating an approximate 22 mm artifact associated with the sensor. D Post-operative CT image showing the sensor adjacent to a shunt catheter within the cortex.
