Abstract: A device (100) includes a leg engaging section (101) and a foot engaging section (102) intersecting at a heel receiver (103). The leg engaging section and the foot engaging section define a leg insertion aperture (104). A compressible cushion layer (402) is disposed at least in the leg engaging section. At least one bolster tube (401) is disposed interior the leg engaging section. The bolster tube (401) can be selectively removable through one or more apertures (1105,1106).

Abstract: A heel protector (100) includes a leg engaging section (101) and a foot engaging section (102) intersecting at a heel receiver (103). The leg engaging section (101) and the foot engaging section (102) define a leg insertion aperture (104). The leg engaging section (101) defines at least one aperture (203) disposed in an ankle region (205) to permit a connection tube (1002) extending from an inflatable bladder (901) of a compression device (800) to pass therethrough. The heel protector (100) and compression device (800) work together as a rehabilitation system (1300).

Abstract: Disclosed are nanostructures comprising a ribonucleic acid (RNA) scaffold comprising a hexameric tetrahedral core. The tetrahedral core may comprise four hexameric RNA nanorings linked together. Related pharmaceutical compositions, methods of modulating the expression of a target gene in a mammal, methods of treating or preventing a disease in a mammal, and methods of producing a hexameric tetrahedral RNA nanostructure are also disclosed.

Abstract: Disclosed are DNA/RNA hybrid nucleic acid nanoparticles comprising at least one trigger toehold or at least one exchange toehold, wherein each at least one trigger toehold and the at least one exchange toehold independently comprise DNA and/or RNA, and at least one single stranded RNA output strand, wherein no portion of the at least one trigger toehold hybridizes to any portion of the at least one output strand, the at least one trigger toehold is complementary and hybridizes to a first target sequence when the nanoparticle is in the presence of the first target sequence, and the nanoparticle does not contain the target sequence. Related pharmaceutical compositions, methods of treating a patient with a disease or condition, and methods of diagnosing a patient with a disease or condition are also disclosed.
