The role of long non-coding RNAs and circular RNAs in bone regeneration: Modulating miRNAs function.

Although bone is a self-healing organ and is able to repair and restore most fractures, large bone fractures, about 10%, are not repairable. Bone grafting, as a gold standard, and bone tissue engineering using biomaterials, growth factors, and stem cells have been developed to restore large bone defects. Since bone regeneration is a complex and multiple-step process and the majority of the human genome, about 98%, is composed of the non-protein-coding regions, non-coding RNAs (ncRNAs) play essential roles in bone regeneration.

[Orographic Influences on the Spatial Distribution of PM on the Fen-Wei Plain].

Topography not only has an effect on the spatial distribution of pollutants by restricting populations and industrial activities, but also affects the formation, transmission, accumulation, diffusion, and sedimentation of PM. Topography is, therefore, an essential variable for understanding the spatial distribution of PM, especially in basin areas. Based on gridded data and both natural and human indexes, this paper examines orographic effects on the distribution of PM on the Fen-Wei Plain based on the change point method, regression, the geographical detector method, and bivariate spatial autocorrelation.
