Abstract: Local delivery formulations of the antineoplastic and microbicide agent acriflavine, and methods of making and using thereof are significantly more efficacious at increasing the median survival of subjects with proliferative disease than systemic administrations of acriflavine. The local delivery formulations of acriflavine show a dose-dependent increase in the median survival of subjects. The local delivery forms provide the increased efficacy without the toxicity associated with systemic administration of the agent.

Abstract: A motion-compensated injector system includes a handheld tool having a hollow shaft with a distal end for insertion into tissue of a subject. The system also includes an optical coherence tomography-based optical detection system having an optical fiber with a distal end at a fixed distance from the distal end of the hollow shaft, and an optical sensor to receive a signal from the optical fiber. The system further includes an actuator to move the hollow shaft in an axial direction, and a control unit to control the actuator. The optical detection system can monitor a distance between the distal end of the optical fiber and a reference portion of the tissue of the subject, and the control unit can control the actuator to move the hollow shaft to compensate for relative motion between the handheld tool and the portion of the tissue.

Abstract: Synthetic representative HCV subtypes, including a 1a and 1b genome, dubbed Bole1a and Bole1b, are provided using an inventive method of Bayesian phylogenetic tree analysis, ancestral sequence reconstruction and covariance analysis. Bole1a branches centrally among 390 full-genome sequences used in its design, a carefully curated 143 sequence full-genome dataset, and separate genomic regions including an independent set of 214 E1E2 sequences from a Baltimore cohort. Bole1a is phylogenetically representative of widely circulating strains. Full genome non-synonymous diversity comparison and 9-mer peptide coverage analysis showed that Bole1a is able to provide more coverage (94% and 78% respectively) than any other sequence in the dataset including H77, a traditional reference sequence. Bole1a also provides unsurpassed epitope coverage when compared to all known T cell epitopes.

Abstract: The present invention establishes a new standard for investigative studies of patient-specific, genetic cardiac diseases at a functional, tissue level by creating a novel platform for the study of cardiac related diseases, including cardiac conduction dysfunction, arrhythmias and depressed contractility for example. Provided herein are novel compositions of human engineered heart slices (EHS) formed from thin slices of decellularized cardiac tissue. Also included are compositions comprising a hybrid of decellularized tissue and organotypic organ slice technology. Intact mammalian hearts are precision cut to obtain thin slices in a range of thicknesses, decellularized, and seeded with various mammalian cells which can be from a variety of sources. Methods of investigation of many diseases and methods of use of these compositions for screening compounds for therapeutic purposes are also provided.

Abstract: The invention relates to N-hydroxysulfonamide derivatives that donate nitroxyl (HNO) under physiological conditions and are useful in treating and/or preventing the onset and/or development of diseases or conditions that are responsive to nitroxyl therapy, including heart failure and ischemia/reperfusion injury. Novel N-hydroxysulfonamide derivatives release HNO at a controlled rate under physiological conditions, and the rate of HNO release is modulated by varying the nature and location of functional groups on the N-hydroxysulfonamide derivatives.

Abstract: An embodiment in accordance with the present invention provides a new MRI method to image the buildup of exchange transfer processes from nuclei in mobile solute molecules in tissue via another molecule (e.g. solvent such as water). The pulse sequence can detect Chemical Exchange Saturation Transfer (CEST), relayed Nuclear Overhauser Enhancement (rNOE) CEST, and selective induced exchange transfer processes. Further, the proposed MRI pulse sequence involves acquiring two or more images with a difference in waiting period (delay) after a radiofrequency excitation, saturation pulse, or series of such pulses. This produces a series of exchange transfer images sensitive to the speed of transfer of changes in magnetization. Subtracting two images or fitting a time series produces maps with minimum interference from direct water saturation and from semi-solid magnetization transfer and other fast exchanging protons.

Abstract: A computational sensing array includes an array of sensing elements. In each sensing element, a first signal is generated from a transducer. A second signal is produced by a collection unit in response to receiving the first signal. The second signal may be modified, in a conditioning unit. A sensing element preprocessing unit generates a word representing the value of the modified second signal, and may produce an indication of change of the first signal. A current value of the word may be stored in a state holding element local to the sensing element, and a previous value of the word may be retained in a further state holding element local to the sensing element.
