Current nonsurgical treatments of discogenic lumbar radiculopathy are neither effective nor safe. Our prior studies have suggested that hydroxylated fullerene (fullerol) nanomaterial could attenuate proinflammatory cytokine tumor necrosis factor alpha (TNF-α)-induced neuroinflammation and oxidative stress in mouse dorsal root ganglia (DRG) and primary neurons. Here, we aim to investigate the analgesic effect of fullerol in a clinically relevant lumbar radiculopathy mouse model and to understand its underlying molecular mechanism in mouse DRGs and neurons. Surprisingly, single and local application of fullerol solution (1 M, 10L) was sufficient to alleviate ipsilateral paw pain sensation in mice up to 2 weeks postsurgery. In addition, microCT data suggested fullerol potentially promoted disc height recovery following injury-induced disc herniation. Alcian blue/picrosirius red staining also suggested that fullerol promoted regeneration of extracellular matrix proteins visualized by the presence of abundant newly formed collagen and proteoglycan in herniated discs. For in vitro DRG culture, fullerol attenuated TNF-α-elicited expression of transient receptor potential cation channel subfamily V member 1 (TRPV-1) and neuropeptides release (substance P and calcitonin gene-related peptide). In addition, fullerol suppressed TNF-α-stimulated increase in intracellular Ca concentrations in primary neurons. Moreover, Western blot analysis in DRG revealed that fullerol's beneficial effects against TNF-α might be mediated through protein kinase B (AKT) and extracellular protein-regulated kinase (ERK) pathways. These TNF-α antagonizing and analgesic effects indicated therapeutic potential of fullerol in treating lumbar radiculopathy, providing solid preclinical evidence toward further translational studies.
Objective. To evaluate the impact of animated videos of oral solid dosage form manufacturing as visual instructional aids on pharmacy students' perception and learning. Design. Data were obtained using a validated, paper-based survey instrument designed to evaluate the effectiveness, appeal, and efficiency of the animated videos in a pharmaceutics course offered in spring 2014 and 2015. Basic demographic data were also collected and analyzed. Assessment data at the end of pharmaceutics course was collected for 2013 and compared with assessment data from 2014, and 2015. Assessment. Seventy-six percent of the respondents supported the idea of incorporating animated videos as instructional aids for teaching pharmaceutics. Students' performance on the formative assessment in 2014 and 2015 improved significantly compared to the performance of students in 2013 whose lectures did not include animated videos as instructional aids. Conclusions. Implementing animated videos of oral solid dosage form manufacturing as instructional aids resulted in improved student learning and favorable student perceptions about the instructional approach. Therefore, use of animated videos can be incorporated in pharmaceutics teaching to enhance visual learning.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
