spinal cord injury (sci) is one of the devastating conditions leading to functional and neurological deficits following road traffic accidents. to date, there is no definite treatment for repairing damaged spinal cord tissue. in this regard, cell therapy opens a new window in front of scientists by using different cells such as mesenchymal stem cells, olfactory ensheathing cells, schwann cells,...

Our challenge is clear: Instead of relegating teachers to the role of production workers—with no say in org a n i z i n g their schools for excellence— we need to enlist teachers as full partners, indeed, as co-managers of their schools. Instead of contracts that reduce flexibility and restrict change, we—and our schools— need contracts that empower and enable. This new collaboration is not abo...

Because of the limitation in arable lands and water resources, the development of agriculture sector is only possible by increasing of resources use efficiency with the minimum damage to production bed through effective use of modern technologies. Among these, nanotechnology has the potential to revolutionize the agricultural systems, biomedicine, environmental engineering, safety and security,...

MicroRNAs (miRNAs) are small, endogenous RNAs that regulate gene expression in plants and animals. In plants, these approximately 21-nucleotide RNAs are processed from stem-loop regions of long primary transcripts by a Dicer-like enzyme and are loaded into silencing complexes, where they generally direct cleavage of complementary mRNAs. Although plant miRNAs have some conserved functions extend...
