Recapitulating Endochondral Ossification for Bone Repair: From Development to Engineering Strategy
Advanced Healthcare Materials, EarlyView.This review summarizes the developmental basis of endochondral ossification (ECO) and its applications in bone tissue engineering (BTE). It first outlines the key biological processes and signaling pathways underlying ECO, then discusses biomaterial‐based engineering strategies derived from these principles, and finally highlights future directions for

Matrix Viscoelasticity Regulates Dendritic Cell Migration and Immune Priming
Advanced Materials, EarlyView.Matrix viscoelasticity is a key mechanical feature of the tumor microenvironment but remains poorly understood in immune regulation. Here, we develop a tunable collagen platform to decouple viscoelasticity from stiffness and show that slow‐relaxing matrices constrain dendritic cell migration by limiting actomyosin‐driven matrix remodeling, thereby ...

Effect of heavy store dressing with rock phosphate on a fine sand soil
Agricultural and Food Science, 1969 Results are reported of a long-term field trial on acid fine sand soil in which the effects of store dressing with rock phosphate in amounts of 0, 4000, 8000, or 12000 kg/ha was studied comparing them with an annual application of 200 kg/ha of ...

Applying Hubbert Curves and Linearization to Rock Phosphate [PDF]
Rock phosphate is a critical, nonrenewable resource for which there is no known substitute in agriculture. Cordell, Drangert, and White (2009) use Hubbert methodology (1956) to estimate the peak--the year after which production will monotonically decline-
