Following severe Spinal Cord Injury (SCI), regeneration is inadequate, and functional recovery is incomplete. The occurrence of oxidative stress and the spread of inflammation play a crucial role in the failure to regenerate the injury site. In this way, we explored the neuroprotective effects of PhotoBioModulation (PBM), as the main factor in controlling these two destructive factors, on SCI. fifty-four female adult Wistar rats divided into three groups: sham group (just eliminate vertebra lamina, n = 18), SCI group (n = 18), and SCI-PBM group which exposed to PBM (150 MW, 50 min/day, 14 days, n = 18). After SCI induction at the endpoint of the study (the end of 8 week), we took tissue samples from the spinal cord for evaluating the biochemical profiles that include Catalase (CAT), Malondialdehyde (MDA), Superoxide Dismutase (SOD), Glutathione Peroxidase (GSH-PX) levels, immunohistochemistry for Caspase-3, gene expressions of Interleukin-1β (IL-1β), Tumor Necrosis Factor-alpha (TNF-α), and Interleukin (IL-10). Also, stereological assessments evaluated the spinal cord, central cavity volumes, and numerical density of the glial and neural cells in the traumatic area. The open-field test, rotarod test, Narrow Beam Test (NBT), Electromyography recording (EMG) test and the Basso-Beattie-Bresnehan (BBB) evaluated the neurological functions. Our results showed that the stereological parameters, biochemical profiles (except MDA), and neurological functions were markedly greater in the SCI-PBM group in comparison with SCI group. The transcript for the IL-10 gene was seriously upregulated in the SCI-PBM group compared to the SCI group. This is while gene expression of TNF-α and IL-1β, also density of apoptosis cells in Caspase-3 evaluation decreased significantly more in the SCI-PBM group compared to the SCI group. Overall, using PBM treatment immediately after SCI has neuroprotective effects by controlling oxidative stress and inflammation and preventing the spread of damage.

Mutations in Delta Like Non-Canonical Notch Ligand 1 (DLK1), a paternally expressed imprinted gene, underlie central precocious puberty (CPP), yet the mechanism remains unclear. To test the hypothesis that DLK1 plays a role in gonadotropin releasing hormone (GnRH) neuron ontogeny, 75 base pairs were deleted in both alleles of DLK1 exon 3 with CRISPR-Cas9 in human pluripotent stem cells (hPSCs). This line, exhibiting More than 80% loss of DLK1 protein, was differentiated into GnRH neurons by dual SMAD inhibition (dSMADi), FGF8 treatment and Notch inhibition, as previously described, however, it did not exhibit accelerated GNRH1 expression.

The thermal grill, in which innocuous warm and cool stimuli are interlaced, can produce a paradoxical burning pain sensation-the thermal grill illusion (TGI). Although the mechanisms underlying TGI remain unclear, prominent theories point to spinal dorsal horn integration of innocuous thermal inputs to elicit pain. It remains unknown whether the TGI activates peripheral nociceptors, or solely thermosensitive afferents that are integrated within the spinal cord to give rise to a painful experience.

Objectives: This study aimed to investigate the effects of repeated exposure to sevoflurane as an anesthetic agent during various developmental stages, namely neonatal, preadolescent, and adult, on behavioral, synaptic, and neuronal plasticity in male and female Wistar rats.
Methods: Rats were exposed to sevoflurane during three developmental stages: neonatal (PN7), pre-adolescence (PN28), and adulthood (PN90). Behavioral performance was evaluated with the Morris Water Maze.

Background: Immunotherapy holds significant yet underexplored potential for low-grade glioma (LGG) treatment. We therefore interrogated the role of Fanconi Anemia Complementation Group C (FANCC) as a novel immune checkpoint regulator given its spatial correlation with tumor microenvironments and clinical associations with immunosuppressive markers.
Objectives: FANCC is implicated in various tumor progressions; its role in LGG remains unexplored.
