In this research, the hydrophilic structure of multi-walled carbon nanotubes (MWCNTs) was modified by synthesizing polycitric acid (PCA) and attaching folic acid (FA) to create MWCNT-PCA-FA. This modified nanocomplex was utilized as a carrier for the lipophilic compound curcumin (Cur). Characterization techniques including TGA, TEM, and UV-visible spectrophotometry were used to analyze the nanocomplex.

Pharmacological therapy options for spinal cord injury (SCI) in acute phase have so far been limited, thus we focused on Calcitriol, FDA-approved biologically active form of vitamin D whose neuroprotective effects are increasingly recognized, to ameliorating damage following acute SCI in rats. Calcitriol (1 μg/kg) treatment for 7 consecutive days after SCI was compared SCI control and Sham control rat groups. Calcitriol-treated group had significantly improved outcome in standard functional recovery evaluation test (BBB) 12 weeks after SCI compared to SCI control, which was confirmed by increased ventral horn motor neurons in Calcitriol-treated group.
