Results of an analytical study of spacecraft deposition contamination by internal reflection spectroscopy [PDF]

open access: yes
Outgassing, deposition, and desorption kinetics of silicone compounds, are examined as examples of optical surface contaminants of spacecraft windows. Their behavior in a space environment after exposure to ultraviolet radiation is also examined. The use

Conditioned Media from Mechanically Stimulated Macrophages Upregulate Osteogenic Genes in Human Mesenchymal Stromal Cells

open access: yesAdvanced Healthcare Materials, EarlyView.
Bone fracture healing is a complex, timely orchestrated scenario involving multiple cell types and a plethora of cytokines and regulatory factors. To gain further insight, an in vitro model to a) study macrophage polarization under mechanical load in a fibrin hydrogel and b) subsequently assess the effect of conditioned media derived from macrophages ...

Immunomodulation With Local, Sustained Delivery of Pituitary Adenylate Cyclase Activating Polypeptide Results in Improved Functional Recovery in Stroke‐Injured Mice

open access: yesAdvanced Healthcare Materials, EarlyView.
The tissue and functional benefits are demonstrated with local, sustained delivery of an anti‐inflammatory peptide, pituitary adenylate cyclase‐activating polypeptide (PACAP), for stroke treatment in a mouse model. Prolonged PACAP treatment modulated astrocyte and microglia toward pro‐reparative phenotypes, enhanced neuroprotection and preservation of ...

Atomic oxygen effects on spacecraft materials: The state of the art of our knowledge [PDF]

open access: yes
In the flight materials exposure data base extensive quantitative data is available from limited exposures in a narrow range of orbital environments. More data is needed in a wider range of environments as well as longer exposure times.
