    Abstract: Examples of heat exchanger systems for active radiative cooling are described. In one example, the system includes a heat exchanger and a spectrally selective surface material on at least one surface of the heat exchanger. The spectrally selective surface material exhibits high reflectivity at shorter wavelengths and high emissivity at longer wavelengths. The system can also include an active cooling system in some cases to actively transfer heat to the heat exchanger. The use of spectrally selective surfaces that operate at temperatures exceeding that of the outdoor ambient for which convective losses augment radiation losses have advantages over passive cooling, such as but not limited to: providing a better match to cooling loads, reducing the heat rejection surface area required to achieve a desired cooling rate, and increasing the heat transferred to deep space through the atmospheric window so as to simultaneously cool infrastructure, devices, buildings, and Earth.

    Abstract: A barrier system is provided for use in reducing infections associated with post-operative surgical incision and/or a percutaneous medical device, such as a catheter, that is disposed within the surgical incision. Such a barrier system may include: a barrier device having a skin-contacting surface and a catheter-receiving surface; and an adhesive composition configured for adhering to skin, the barrier device, and/or the catheter so as to form a barrier at or adjacent to an incision in the skin where the catheter is percutaneously inserted through the skin. A tensioning anchor and associated system of two or more tensioning anchors is provided for post-operative wound closure. A method for applying and removing the barrier device and tensioning anchors is also provided.

    Abstract: An implantable hydrogel precursor composition can include: a cross-linkable polymer matrix that is biocompatible; and a plurality of polymer particles in the cross-linkable polymer matrix. The cross-linkable polymer matrix can include a cross-linkable hyaluronic acid polymer that has cross-linkable functional groups. The hyaluronic acid polymer can be a methacrylated hyaluronic acid polymer. The methacrylated hyaluronic acid polymer can have a molecular weight from about 500 kDa to about 1.8 MDa. The polymer particles can include a cross-linked hyaluronic acid. The cross-linkable polymer matrix having the polymer particles has a yield stress. The cross-linkable polymer matrix having the polymer particles has shape retention at physiological temperatures. The composition can include live cells in the cross-linkable polymer matrix. The composition can include a biologically active agent in the cross-linkable polymer matrix.

    Abstract: Cyclic tetrapeptide stereochemical isomers of CJ-15,208, pharmaceutical compositions from such cyclic tetrapeptides, and methods of using such pharmaceutical compositions. The cyclic tetrapeptide compounds and pharmaceutical compositions disclosed herein are potent analgesics active in several pain models with generally minimal tolerance and reduced likelihood to induce addiction relative to other known opiates.
