Abstract: The invention is directed to methods and compositions for obtaining uniform sized muscle fiber fragments for transplantation. These muscle fiber fragments are able to reconstitute into long fibers that are oriented along native muscle. The implanted muscle cells integrate with native vascular and neural network, as confirmed by histology and immunohistochemistry. This invention is particularly advantageous because autologous muscle can be harvested from a donor site, processed and injected into target sites in the operating room. The fragmented muscle fibers can be readily integrated within the host.
Abstract: Provided herein are artificial lung organoids. The artificial lung organoids may include an epithelial cell layer comprising mammalian lung epithelial cells, a stromal cell layer comprising mammalian lung fibroblast cells and an endothelial cell layer comprising mammalian endothelial cells. The artificial lung organoids may optionally include a porous membrane between said epithelial cell layer and said stromal cell layer and/or between said stromal cell layer and said endothelial lung cell layer.
Abstract: A cell composition composed of spermatogonial stem cells, Sertoli cells, Leydig cells and optionally peritubular cells, is provided, as is a culture composition, artificial testicular construct, hydrogel composition, and device containing the same. A method for using the device as a physiologically relevant in vitro model of human testicular function to screen compounds for pharmacological or toxicological activity is also provided.

Abstract: Medical kits and methods for performing small incision DLEK include a corneal transplantation donor tissue graft formed into an implantable and compact rolled configuration using the flexible substrate.
Abstract: Post-image acquisition methods, circuits and systems for evaluating medical images of a subject register a region of interest in a first medical image taken at a first point in time to the region of interest in a second image taken before or after the first medical image with voxels from the first and second medical images having a voxel-wise correspondence. The methods, circuits and systems can use line and/or shape changes of defined 3-D finite elements to electronically determine directional, shear and volumetric changes of the voxels in the region of interest between the first and second medical images.

Abstract: Solid particulate measuring devices, systems, and methods for using the devices and systems are provided for easier and more accurate measurement of specific volumes. For example, a specific dose of a pharmaceutical multiparticulate composition can be measured out accurately and easily in a variety of settings using the devices and systems described herein.
Abstract: In some embodiments, thermoelectric apparatus and various applications of thermoelectric apparatus are described herein. In some embodiments, a thermoelectric apparatus described herein comprises at least one p-type layer coupled to at least one n-type layer to provide a pn junction, and an insulating layer at least partially disposed between the p-type layer and the n-type layer, the p-type layer comprising a plurality of carbon nanoparticles and the n-type layer comprising a plurality of n-doped carbon nanoparticles.
Abstract: Peptide constructs comprising a mitochondrial antiviral-signaling protein (MAVS) peptide and a cell penetration peptide are disclosed, which are useful for stimulating interferon production in vitro and in vivo. Lactate has been discovered to inhibit glycolysis-mediated retinoic acid-inducible gene I (RIG-I) like receptor signaling by directly binding to the MAVS transmembrane (TM) domain and preventing MAVS aggregation; peptide constructs according to the disclosure can prevent or reverse this inhibition to stimulate interferon production. Methods for stimulating interferon production in a cell are also described, as well as methods for the treatment of viral infections and cancer.
Abstract: Methods are disclosed for forming tissue engineered, tubular bowel constructs from intestinal circular smooth muscle cells and enteric neural progenitor cells. The intestinal smooth muscle cells and neural progenitor cells can be seeded on a mold with a surface texture that induces longitudinal alignment of the intestinal smooth muscle cells and co-cultured until an innervated aligned smooth muscle sheet is obtained. The innervated smooth muscle sheet can then be wrapped around a tubular scaffold to form an intestinal tissue construct.
Abstract: Methods are provided to produce optimal fractionations of charged keratins that have superior biomedical activity. Also provided are medical implants coated with these keratin preparations. Further provided are methods of treating blood coagulation in a patient in need thereof.
Abstract: Modified alginates are described herein along with hydrogels comprising the same. A modified alginate may be prepared by reacting alginate and an aromatic compound (e.g., an aromatic amine) and/or pH sensitive compound. The modified alginates, hydrogels, and/or methods described herein may be used to coat and/or encapsulate at least a portion of a bioactive substance, optionally for oral delivery in humans and other animals.
