Abstract: A microfluidic device includes a first layer of a porous material with pores having a first average pore size and a liquid-receiving area through which a liquid sample is received into the microfluidic device. A second layer of another porous material, with pores of a second average pore size, is stacked below the first layer and has a channel with a starting end positioned at least in part in an overlapping manner with the liquid-receiving area. The channel has a terminating end extending laterally at a predetermined wicking distance from the starting end. The first average pore size and the second average pore size cause a wicking effect in which at least some of the liquid sample flows along the channel at least a portion of the wicking distance between the starting end and the terminating end.

Abstract: Methods for improved imaging of internal tissue structures, such as lesions in the peritoneum, are disclosed employing color-weighted Polarization Enhanced Light (mPEL) imaging. A target tissue can be Illuminated with light of defined polarization at a plurality of wavelengths or wavelength bands. Scattered light from the tissue is collected and its polarization states analyzed and detected either via a polarization sensitive camera or a combination or polarizing filters and a standard camera. Light detected at distinct polarization states and colors is weighted by a factor and combined to yield an image that results in optimized visualization of lesions and/or discrimination of malignant from benign lesions. The factors may be identified based on a combination of Monte Carlo simulations and regression analysis to yield enhanced sensitivity to the tissue scattering power. Alternatively, the factors may be identified through machine learning based optimization algorithms to optimize tissue classification.

Abstract: Cell penetrating peptides that target many cells types including cells of the retina and cornea with high efficiency are provided herein. These peptides can be used to deliver cargo molecules across a plasma membrane, without the need for chemical conjugation. Compositions and viral vectors comprising these cell-penetrating peptides are also provided. Methods of using the peptides, compositions and viruses to deliver various agents to target cells and tissues are also provided.
Abstract: The tumor stroma, which accounts for a large part of the tumor mass, represents an attractive target for the delivery of diagnostic and therapeutic compounds. Here, the focus is notably on a subpopulation of stromal cells, known as cancer-associated fibroblasts, which are present in more than 90% of epithelial carcinomas, including pancreatic, colon, and breast cancer. Cancer-associated fibroblasts feature high expression of FAP, which is not detectable in adult normal tissue but is associated with a poor prognosis in cancer patients. The present invention provides small-molecule radiopharmaceutical and imaging agents based on a FAP-specific inhibitor.

Abstract: The inventions provided herein relate to compositions, methods, delivery devices and kits for repairing or augmenting a tissue in a subject. The compositions described herein can be injectable such that they can be placed in a tissue to be treated with a minimally-invasive procedure (e.g., by injection). In some embodiments, the composition described herein comprises a compressed silk fibroin matrix, which can expand upon injection into the tissue and retain its original expanded volume within the tissue for a period of time. The compositions can be used as a filler to replace a tissue void, e.g., for tissue repair and/or augmentation, or as a scaffold to support tissue regeneration and/or reconstruction. In some embodiments, the compositions described herein can be used for soft tissue repair or augmentation.

Abstract: An intelligent system, such as an autonomous robot agent, includes systems and methods to learn various aspects about a task in response to instructions received from a human instructor, to apply the instructed knowledge immediately during task performance following the instruction, and to instruct other intelligent systems about the knowledge for performing the task. The learning is accomplished free of training the intelligent system. The instructions from the human instructor may be provided in a natural language format and may include deictic references. The instructions may be received while the intelligent system is online, and may be provided to the intelligent system in one shot, e.g., in a single encounter or transaction with the human instructor.
Abstract: The disclosure provides methods and compositions for affecting the development of antigen presenting cell (APC, e.g., a macrophage or dendritic cell). The methods include maturing an APC, promoting anti-inflammatory phenotype, promoting development of a T regulatory cell (Treg) from a naive T cell. The methods generally include exposing an APC to a tryptophan derived microbiota metabolite (TDMM), such as an anti-inflammatory or pro-mucosal TDMM, and permitting the APC to mature. In some embodiments, the conditioned APC is exposed to a naive T cell to further promote development of a T regulatory cell (Treg). In some embodiments, the TDMM is selected from the group consisting of indole, indole-3-acetate, 5-hydroxyindole, and indole-3-pyruvate.
