background and aims. connective tissue grafts with and without periosteum is used in regenerative treatments of bone and has demonstrated successful outcomes in previous investigations. the aim of present study was to evaluate the effectiveness of connective tissue graft with and without periosteum in regeneration of intrabony defects. materials and methods. in this single-blind randomized spli...

Subsurface structures and especially the interactions between pores, roots other organic matter elements have a strong impact on ecosystem functioning. Yet despite recent progress in application of X-ray Computed Microtomography (µCT) to soil structure agricultural science, applications more complex heterogeneous substrates found natural soils, specifically wetland remain sparse. We apply µCT h...

Suboptimal nitrogen (N) availability is a primary constraint for crop production in developing nations, while in rich nations, intensive N fertilization carries substantial environmental and economic costs. Therefore, understanding root phenes that enhance N acquisition is of considerable importance. Structural-functional modeling predicts that root cortical aerenchyma (RCA) could improve N acq...
