Abstract: An artificial chamber including a first conduit, a second conduit, a third conduit, and a wall defining a space; in which the first conduit and the second conduit are positioned opposite one another; in which the third conduit is opposite the wall; and in which the wall has a concave surface is disclosed. The chamber can be part of a system for providing pulmonary support. The system includes the chamber and a first pump connected to the third conduit, and connected to a fourth conduit; in which the chamber receives fluid via the first conduit and the second conduit, in which the first pump receives fluid from the chamber via the third conduit; and in which the fourth conduit transports fluid from the first pump to a first blood vessel. Methods of making a chamber and a system, and methods of using the chamber and system are also disclosed.

Abstract: A glomerulus on a chip (GOAC) to recapitulate the human glomerular filtration barrier, the structure responsible for filtering the blood and preventing the loss of proteins, is provided using human podocytes and glomerular endothelial cells seeded into microfluidic chips. In long-term cultures, cells maintain their morphology, form capillary-like structures and express slit diaphragm proteins. This system recapitulates functions and structure of the glomerulus, including permselectivity. When exposed to sera from patients with anti-podocyte autoantibodies, the chips show albuminuria proportional to patients' proteinuria, phenomenon not observed with sera from healthy controls or individuals with primary podocyte defects. Also shown is its applicability for renal disease modeling and drug testing.

Abstract: Zebrafish are a powerful model for investigating cardiac repair due to their unique regenerative abilities, scalability, and compatibility with many genetic tools. However, characterizing the regeneration process in live adult zebrafish hearts has proved challenging because adult fish are opaque and explanted hearts in conventional culture conditions experience rapid declines in morphology and physiology. To overcome these limitations, we fabricated a fluidic device for culturing explanted adult zebrafish hearts with constant media perfusion that is also compatible with live imaging. Unlike hearts cultured in dishes for one week, the morphology and calcium activity of hearts cultured in the device for one week were largely similar to freshly explanted hearts.

Abstract: Examples are described for dynamically applying a digital watermark to a file, such as a dataset of genomic sequencing data. In one example, a method of dynamically applying a watermark to at least a portion of a file includes generating, using a secret key, a first random seed, generating, using the first random seed, an ordered pseudorandom set of integers, generating, using entity information and timing information, a second random seed, selecting, using the second random seed, a subset of the ordered pseudorandom set of integers, and modifying data at data locations in the file corresponding to at least a portion of the identifiers included in the subset to generate a watermarked file. The method may further include performing a check to determine whether the watermark is present in a file using a sequence of watermark elements that are generated based on the secret key.

Abstract: The present disclosure relates in some aspects to chimeric signaling receptors containing an extracellular domain capable of binding a molecule, such as an immunosuppressive cytokine, and a MyD88-containing intracellular domain capable of engaging a signaling pathway to activate an immune cell. In some aspects, the disclosure further relates to engineered cells, such as T cells, and compositions comprising the chimeric signaling receptors or engineered cells, and methods and uses thereof. In some embodiments, the cells may further express a genetically engineered recombinant antigen receptor directed against an antigen, such as a chimeric antigen receptor (CAR) or recombinant T cell receptor (TCR) and, in some cases, secrete a recombinant molecule, for example, a bispecific antibody.

Abstract: The present invention provides an advancement in the art of cardiac pacemakers. The invention provides a novel and unobvious pacemaker system that comprises at least one pacemaker and that is, to a large extent, self-controlled, allows for long-term implantation in a patient, and minimizes current inconveniences and problems associated with battery life. The invention further includes a mechanism in which at least two pacemakers are implanted in a patient, and in which the pacemakers communicate with each other at the time of a given pacing or respiratory event, without any required external input, and adjust pacing parameters to respond to the patient's need for blood flow. The invention further provides a novel design for a pacemaker in which the pacemaker electrode is connected to the pacemaker body by a lead that is configured to allow the pacemaker to lie parallel to the epicardial surface and to reduce stress on the pacemaker and heart tissue.

Abstract: Examples are described for dynamically encrypting and/or decrypting a file formed of multiple blocks of ordered data. In one example, a method of dynamically encrypting a file to enable partial decryption of the file includes generating, using a secret key and one or more initialization vectors, a keystream for the multiple blocks of ordered data, encrypting the multiple blocks of ordered data of the file by performing a logical operation of the keystream with the multiple blocks of ordered data in a one-to-one correspondence, and building a file index of the file to identify location information of the multiple blocks of ordered data. The method may further include dynamically decrypting at least a portion of the file by decrypting at least one selected block of encrypted data of the file using a portion of the keystream, the portion of the keystream corresponding to the at least one selected block.

Abstract: An open coiled pacemaker lead is provided that has improved structural stability and functional life in vivo. The open coiled lead includes an electrically conductive material that is coated or covered by a thin layer of electrically insulative material. The coated coiled lead has adequate spacing between adjacent coils, and has a lumen of sufficient diameter, to allow for infiltration of biological connective tissue onto the surface of the coated coil when maintained in vivo for a sufficient amount of time. Infiltration of the connective tissue essentially uniformly along the entire coiled lead strengthens and lengthens the functional life of the coated coil lead.
