A Modular Bioinstructive Platform Reveals Mechanistic Insights into Additive‐Free, Topography‐Driven Osteogenesis

open access: yesAdvanced Healthcare Materials, EarlyView.
Engineered microparticle topographies direct human mesenchymal stem cell osteogenesis without biochemical additives. This osteogenic commitment is driven by canonical Hedgehog signaling and followed by temporal IGF‐II engagement. Two‐photon polymerization demonstrates spatial control, enabling the engineering of topographical gradients that pattern ...

Temporal Reliability of Willingness to Pay from the National Survey of Fishing, Hunting, and Wildlife-Associated Recreation [PDF]

open access: yes
The U.S. Fish and Wildlife Service's National Survey of Fishing, Hunting, and Wildlife Associated Recreation has been a source of information on wildlife-related recreation since 1955. The contingent valuation method has been used to estimate willingness

A Long‐Lived Human Neurovascular PENTA Culture Model Captures Incomplete Vascular Repair and Glia‐Associated Signaling After Traumatic Brain Injury

open access: yesAdvanced Healthcare Materials, EarlyView.
A long‐lived, five‐cell‐type human neurovascular (PENTA) model recreates vascular disorganization and incomplete repair after traumatic brain injury (TBI). By integrating endothelial, glial, neuronal, and immune components within a 3D scaffold, the platform enables time‐resolved analysis of neurovascular remodeling and provides a human‐relevant system ...

Enhanced Human Antigen‐Specific B Cell Responses Using In Vitro 3D Tonsil Cultures Containing Stromal Cells

open access: yesAdvanced Healthcare Materials, EarlyView.
We developed a fully human 3D tonsil cell culture system incorporating supportive stromal cells that better sustains and activates immune cells than conventional methods. The model generates stronger, more targeted antibody responses to viral antigens and vaccines, providing a physiologically relevant and entirely human platform for studying immune ...

THE NEW CARISSA SHIPWRECK: AESTHETIC IMPACT ON COASTAL RECREATION [PDF]

open access: yes
This paper uses a combination of techniques, including a stated-preference survey, random utility model, visitor count study, and benefits transfer, to estimate the aesthetic impact of the New Carissa shipwreck on coastal recreation.

Recreation in the ME or is it WE jungle [PDF]

open access: yes, 2006
At this years Thinking Recreation symposium I was inspired by the enthusiasm delegates shared for debating, rather than seeking solutions to, a range of issues such as youth deviance, physical inactivity, resource allocation, and managing the environment.

Melt Electrowriting High Resolution Poly(ethylene‐co‐vinyl acetate) Scaffolds for Soft Tissue Engineering

open access: yesAdvanced Healthcare Materials, EarlyView.
This work pioneers melt electrowriting (MEW) of polyethylene vinyl acetate (PEVA) to fabricate ultra‐compliant, high‐resolution scaffolds. By integrating microscale precision with soft tissue‐like biomechanics, PEVA overcomes stiffness‐driven limitations of conventional MEW polymers, establishing a mechanically biomimetic platform for soft tissue ...

Benefit Transfer over Time of Ecosystem Values: the Case of Forest Recreation [PDF]

open access: yes
We conduct a functional benefit transfer over 20 years of total willingness to pay based on car-borne forest recreation in 52 forests, using a mixed specification of a random utility model and geographic information systems to allow heterogeneous ...
