Additionally, the preparation of bio-based photo curable thermosetting resins that have tailorable thermal and mechanical properties is provided. All monomers and polymers described herein are useful in a variety of applications, including additive manufacturing applications.

Abstract: Described herein is a biocompatible injectable dosimeter. The injectable dosimeter comprises a polymer gel and a radiation dosimeter material distributed in the polymer gel. The dosimeter material in the injectable dosimeter, when radiated, generates a dosimetric signal, which can be used to evaluate the delivery of the radiation. Also described are methods of using the injectable dosimeter, such as to report radiation in real-time and to protect tissues adjacent to the disease sites being irradiated.

Abstract: A composition of matter including two optionally substituted phenol or optionally substituted aniline units separated by a furan spacer has been prepared. In particular, the chemical structure has a novolac bridge between the central furan ring and the two attached optionally substituted phenol and/or optionally substituted aniline units. These compounds can be modified to be used in various polymer resins. This new structure reduces toxicity relative to BPA/F, makes use of renewable chemicals, and produces certain beneficial polymer properties.

Abstract: The present disclosure provides a system and method for producing nanofibers. The system includes an automated track system including a first track having a first face; and a second track having a second face facing the first face of the first track. The first track and the second track are positioned to define a proximal gap and a distal gap. The first track and the second track are adapted and configured to transfer a nanofiber coupled to the first face and the second face from the proximal gap to the distal gap. The system also includes a roving belt that is positioned to be partially disposed within the distal gap and is adapted and configured to decouple the nanofiber from the first face and the second face.

Abstract: A method and computer-based system is provided that assists physicians in detecting early tumor growth and allowing modification of treatment to have a positive impact on medical management, patient morbidity, outcomes and survival times. The method comprises measuring tumor volumes from radiological images to predict growth by a statistical method. The methods allow detection of increases in tumor size earlier than is currently possible and, therefore, advantageous in modifying or optimizing treatment.

Abstract: Methods for detecting Multiple Sclerosis (MS) diagnostic autoantibodies in a subject and generating a subject-specific, MS diagnostic autoantibody profile are described. The methods include contacting an immunoglobulin-containing biological sample from the subject with a system comprising antigens that form immunocomplexes with MS diagnostic autoantibodies, the antigens including general transcription factor II-I, splicing factor 1, and inducible T-cell co-stimulator (ICOS), to form a reaction mixture, under conditions that allow for formation in the reaction mixture of an immunocomplex between each antigen and its corresponding MS diagnostic autoantibody, if its corresponding MS diagnostic autoantibody is present in the sample; and detecting presence or absence of immunocomplexes in the reaction mixture, wherein formation of immunocomplexes between the antigens and their corresponding MS diagnostic autoantibodies indicates presence of the MS diagnostic autoantibodies in the biological sample.
