Polyglycolic acid (PGA) fibre meshes are attractive candidates to transplant cells, but they are incapable of resisting significant compressional forces. To stabilize PGA meshes, atomized solutions of poly(L-lactic acid) (PLLA) and a 50/50 copolymer of poly(D,L-lactic-co-glycolic acid) (PLGA) dissolved in chloroform were sprayed over meshes formed into(More)
We examine graphs that contain a nontrivial link in every embedding into real projective space, using a weaker notion of unlink than was used in Flapan, et al [5]. We call such graphs intrinsically linked in RP 3 . We fully characterize such graphs with connectivity 0 , 1 and 2 . We also show that only one Petersen-family graph is intrinsically linked in RP(More)
Intervention-based assessment, a systematic form of prereferral intervention, represents a viable alternative to "test and place" models for identifying and teaching children with a variety of learning-related problems in schools. Data obtained from 13 schools participating for a third year in a pilot study of statewide implementation of intervention-based(More)
Liver cell transplantation may provide a means to replace lost or deficient liver tissue, but devices capable of delivering hepatocytes to a desirable anatomic location and guiding the development of a new tissue from these cells and the host tissue are needed. We have investigated whether sponges fabricated from poly-L-lactic acid (PLA) infiltrated with(More)
Introduction: Stromatolitic structures preserved at two stratigraphic levels within the 3.47-3.43 Ga War-rawoona Group of Western Australia have been interpreted as some of "the least controversial evidence of early life on earth" and "the oldest firmly established biogenic deposits now known from the geologic re-cord" [1]. The structures were said to have(More)
Polymers of lactic and glycolic acid are attractive candidates to fabricate devides to transplant cells and engineer new tissues. These polymers are biocompatible, and exhibit a wide range of erosion times and mechanical properties. This manuscript describes the fabrication and characterization, in vitro and in vivo, of hollow, tubular devices from porous(More)
