Abstract: Systems and methods for targeted gene modification, targeted insertion, perturbation of gene transcripts, and nucleic acid editing. Novel nucleic acid targeting systems comprise components of CRISPR systems and non-LTR retrotransposon elements.

Abstract: Devices and methods are provided for non-invasive sensing of tissue fluid distribution in a patient. The device includes one or more magnets configured to provide a static magnetic field source; one or more RF transmitter coils connected to a pulse sequence generator which are configured to apply a varying magnetic field to tissues of the patient; one or more RF receiver coils configured to detect a magnetic field generated within tissues of the patient; and a signal acquisition and processor system configured to acquire signals from the RF receiver coils and perform an NMR measurement of a relaxation parameter of hydrogen nuclei within a muscle tissue site of the patient. A single-sided MR sensor device may include permanent magnets arranged in a unilateral linear Halbach array; and RF coils and a processor which are configured to produce a depth-resolved, diffusion-weighted, multicomponent T2 relaxometry measurements of intramuscular fluid shifts in a patient.

Abstract: Methods for assessing steatosis and fibrosis in a patient's liver include (i) measuring a diffusion-weighted relaxometry signal of the liver, or portion thereof; and determining a fibrosis content of the liver or portion thereof based on the measured diffusion-weighted relaxometry signal, or (ii) measuring a relaxometry signal of the liver, or portion thereof; and determining a fat content of the liver or portion thereof based on the measured relaxometry signal. A system for such non-invasive sensing includes a static magnetic field source; RF transmitter coils connected to a pulse sequence generator; RF receiver coils configured to detect a magnetic field generated within liver tissues; and a signal acquisition and processor system configured to acquire signals from the RF receiver coils and perform a relaxation time (T2) relaxometry measurement, wherein the RF transmitter coils and pulse sequence generator are configured to apply a varying magnetic field to the liver tissues.
